Morphological blood parameters and productivity of broiler chickens under t-2 toxicosis and the application of the bioadsorbent "biobon"
One of the pressing issues frequently encountered in modern poultry farming is the emergence and spread of mycotoxicoses, which can negatively affect the health of farm birds and cause significant economic losses for poultry producers. One of the most dangerous mycotoxicoses in industrial poultry farming is T-2 mycotoxicosis, caused by the trichothecene mycotoxin produced by fungi of the Fusarium genus. It is known that T-2 toxin has pronounced cytotoxic, immunosuppressive, and hematotoxic effects, leading to reduced productivity indicators in poultry, a weakened immune status, and increased susceptibility to infections, which often develop as a result of the negative impact of mycotoxins on the bird's body. The aim of our study was to investigate the effect of T-2 toxin on the morphological parameters of blood and the productivity of broiler chickens, as well as to assess the effectiveness of the feed bioadsorbent “BioBon” in preventing T-2 toxicosis. The experiment included three groups of broiler chickens, each consisting of 30 birds: a control group, an experimental group 1 (with the addition of 0.2 mg/kg of T-2 toxin to the feed), and an experimental group 2 (with the addition of T-2 toxin and the bioadsorbent "BioBon"). From days 15 to 28 and then to 35, the hemoglobin content in the blood of all groups increased, followed by a decrease on day 42. However, we observed a tendency for an increase in hemoglobin levels in the blood of the birds in the second experimental group by 2.40% compared to the control group. On day 28, the broiler chickens in the first experimental group showed a marked decrease in leukocyte count by 22.88% and lymphocyte count by 18.04%, indicating a pronounced immunosuppressive effect of the T-2 toxin when added to the diet of broiler chickens in this group. The bioadsorbent “BioBon”, when added to the compound feed at a dose of 2 kg/ton, neutralized the negative effects of the T-2 toxin on the experimental broiler chickens, resulting in an increase in slaughter weight up to 2917 g, and also contributed to a reduction in the feed conversion ratio to 1.690 kg/kg.
Performance indicators and broiler chicken livability when using yeast cell wall in feeding
Since 2006, the European Union has implemented a ban on the use of feed antibiotics in poultry farming, creating the need to find alternative methods for preventing infectious diseases in commercial poultry. The aim of this study was to evaluate the effectiveness of the prebiotic preparation "Ist Sel Vol", produced by "Angel Yeast LTD", whose active ingredient is a yeast cell wall derived from Saccharomyces cerevisiae, in broiler chicken production. An analysis of its impact on the growth and safety of broiler chickens was conducted. A production trial lasting 38 days was conducted on 74,410 "Cobb-500" broiler chickens, which were divided into two groups. The only difference between the experimental group and the control group was the addition of the prebiotic yeast cell wall preparation "Ist Sel Vol" at a dosage of 1 kg per ton of feed. At the end of the production cycle, a positive stimulatory effect of the tested preparation on the growth and development of broiler chickens was observed. As a result of using the yeast cell wall preparation, the average daily weight gain of broilers in the experimental group was 0.81% higher compared to the control group, and the average carcass weight of chickens from the experimental group was 1.17% higher than the average carcass weight of the control group. The application of the tested prebiotic also contributed to an improvement in feed conversion by 2.4%. The European Efficiency Factor in the experimental group was 3.3% higher than in the control group. Additionally, an increase in the livability rate by 0.5% was recorded in the experimental group. The obtained results demonstrate the effectiveness of the "Ist Sel Vol" yeast cell wall preparation in industrial broiler production and highlight its potential for preventing bacterial diseases and reducing the negative effects of mycotoxins in broiler farming.
Meat quality of broiler chickens using a probiotic preparation
The development of science and new technologies created on the basis of its achievements open up alternative ways to solve food security problems. The priority in this aspect may be the development of new technologies for the creation of combined probiotic preparations. These technologies allow solving existing problems with fundamentally new means, in particular, obtaining a sufficient amount of food that is safe for human health. The development and testing of effective natural preventive preparations and schemes for their application to broiler chickens, especially in the production of organic and functional products, is an urgent issue today for the development, improvement of the efficiency and profitability of the poultry industry. We investigated the effect of the combined probiotic preparation “TIMM-P” on the meat of broiler chickens. The preparation “TIMM-P” was given in courses for 1-5 days, 21-25 and 30-35 days of poultry farming. Determination of the chemical composition of meat in 42-day-old experimental broiler chickens indicates a probable increase in the content of total protein in the muscle tissue of the bird with the use of a probiotic. A probable effect of the probiotic preparation on extending the shelf life of poultry meat was established based on the study of organoleptic and chemical indicators of broiler chicken meat during refrigerated storage. On the 7th and 9th day of storage of carcasses of the experimental group, which was treated with a probiotic, a probable decrease in the pH value, acid and peroxide value of fat in meat was recorded. Thus, oral administration of the probiotic preparation improves the quality indicators of broiler chicken meat and extends its shelf life. Therefore, the complex probiotic preparation “TIMM-P” can be recommended for use during broiler chicken breeding, as well as an alternative to antibiotics in organic poultry farming.
Energy nutrition and nutrient digestibility of high-protein sunflower concentrate in feeding broiler chickens
The studies were conducted on broiler chickens of the cross "Kobb 500" in the research laboratory of "Feed Additives" and "Animal Nutrition and Feed Quality" of the Department of Animal Nutrition and Feed Technology named after P.D. Pshenychny National University of Life Resources and Environmental Sciences of Ukraine. The aim of the study was to investigate the actual energy content and nutrient digestibility of high- protein sunflower concentrate in feeding broiler chickens. The digestibility of nutrients in high-protein sunflower concentrate was carried out in a simple way, with two modifications: by the direct method and by the method of inert substances. Lignin, a natural component of plant-based feeds, was used as an inert substance. The determination of digestibility in broiler chickens was carried out on 12 broilers aged 32-42 days. The chickens were kept in individual cages. The area per head was 0.2 m2, the feeding front was 25 cm, and the watering was 3 cm. The experiment lasted 10 days. During this time, various methods were used to determine digestibility in a group of experimental chickens. The physiological experiment consisted of preparatory and primary periods. During the preparatory period, which lasted 5 days, the bird was accustomed to consuming the studied feed and new conditions of detention, and the level of feed consumption was established. The digestibility of crude protein was relatively high, at 95%. Moreover, the discrepancy between the indicators obtained for determining digestibility by the direct method and the method of inert substances was minimal, less than 1%. The same picture was observed for the digestibility of crude fat; the indicator was within 85%. The discrepancy between the two methods was minimal – 0.5%. The digestibility of structural carbohydrates was low, which is typical for poultry, especially young birds. The total energy value of high-protein sunflower concentrate for broiler chickens is 11.624–13.968 MJ/kg.
Chicken crosses of the breeding company Dominant Genetika s.r.o.
Breeding poultry companies offer chickens of their own selection, the breeding of which is advisable under various technologies, including organic production. The analysis of the gene pool of chickens of the Czech company DOMINANT Genetika s.r.o. allowed to substantiate the advantages of using certain hybrids. The diversity of the proposed hybrids is due to the use of the source material: 14 hybrids were obtained by crossing separate lines of Rhode Island, Sussex and Plymouth breeds, Dominant leghorn D229 – 4 populations of white leghorns, 4 hybrids – leghorns with different plumage colors, 6 hybrids – using the Araucana breed, Dominant darkshell DS109 – the Maran breed, 2 hybrids – the Naked Neck line. The color of the plumage and eggshells varies considerably among the hybrids. The final hybrids are autosexual in plumage coloration or growth rate of flight feathers. The age range for reaching 50% egg production is 22-28 weeks, with a peak egg production of 88-94% at 29-30 weeks of age, with no difference between parent and commercial flocks. The egg production of hens in the commercial flock is 240-320 eggs in 59 weeks, and that of the parent flock – up to 275 eggs with a hatching egg yield of up to 250 eggs in 49 weeks. The hybrids with the highest (62-63 g) and lowest (58 g) egg weight were identified. Egg weight in birds of the parent flock is characterised by greater uniformity. During the productive period, the average daily feed intake was 105-132 g. The liveability rate of the parent flock chickens is 94-97%, and that of the final hybrids is 93-97%. Slow-growing roosters are offered for meat production, which reach a weight of 1842 g on the 77th day with a feed conversion of 2.79 kg and a high content of α-tocopherol and an optimal ratio of fatty acids. The company's chicken crosses can satisfy producers of food eggs and poultry meat for keeping them in households, farms, organic farming, and intensive farming.
Growth of young turkeys at different levels of lysine and methionine in feed
The article examines the effect of using complete feed with different levels of lysine and methionine on the growth of turkeys. Experimental studies were performed on young turkeys of the BIG 6 cross-breeding meat direction. Five experimental groups of birds were formed by the method of balanced groups at the age of one day. The experiment lasted 126 days and was divided into two periods: comparative (7 days) and main (119 days). During the comparative period, the experimental youngsters consumed compound feed of the control group. In the main period of the experiment, the amount of lysine and methionine relative to the poultry feed of the control group decreased or increased proportionally by 5 and 10% according to the periods of cultivation. It was established that different levels of lysine and methionine in compound feed for young turkeys affect its productivity in different ways. In particular, at the end of the experiment, at the age of 126 days, the highest live weight was achieved by turkeys that consumed compound feed with an increase in the amount of lysine and methionine by 5 and 10% – they outnumbered the counterparts of the control group, respectively, by 5.9 (P<0.01) and 3.6%. Poultry that received compound feed with a reduced amount of lysine and methionine were inferior to control peers by 5.6 (P<0.05) and 2.7%, respectively, according to the mentioned indicator. The description of the growth of young turkeys using mathematical methods confirmed the S-shaped ascending shape of the growth curve with high coefficients of determination for each experimental group. It has been proven that in almost all periods of the experiment, young turkeys that consumed compound feed with a higher level of lysine and methionine prevailed in terms of average daily live weight gains of their counterparts, which were fed compound feed with a lower proportion of lysine and methionine. In general, turkeys that consumed compound feed with increased levels of lysine and methionine by 5 and 10% were characterized by higher average daily live weight gains – they exceeded control analogues by the mentioned indicator by 6.1 and 3.6%, respectively. Experimental birds that received combined feed with a reduced amount of lysine and methionine by 10 and 5% were inferior to peers of the 1st group by 5.9 and 2.7%, respectively. It was established that the relationship between different levels of lysine and methionine in compound feed for young turkeys and its average daily weight gain is described by a polynomial line with a reliable approximation coefficient R2=1. At the same time, the correlation analysis showed that there is a direct average relationship between these phenomena (rs=0.6, P<0.005).

Growing of young turkeys with different ratios of lysine and methionine in combined feeds
The article examines the effect of feeding complete ration compound feed with different ratios of lysine and methionine on the productivity of young turkeys. Experimental studies were performed on young turkeys of the "Big-6" cross-breeding meat direction. By the method of balanced groups, five sub-experimental groups of birds were formed at the age of one day. The experiment lasted 126 days and was divided into two periods: comparative (7 days) and main (119 days). During the comparative period, the experimental turkeys consumed compound feed of the control group. In the main period of the experiment, the share of methionine relative to lysine in compound feed decreased or increased by 5 or 10% according to the periods of cultivation. It was established that the different ratio of lysine and methionine in compound feed for young turkeys affects its productivity in different ways. So, at the age of 126 days, turkeys that received compound feed with an increase in the proportion of methionine relative to lysine by 5 and 10% had the highest live weight – they outnumbered the counterparts of the control group by 5.9 (Р<0.05) and 3.6%, respectively. The turkeys, which consumed compound feed with a reduced share of methionine relative to lysine by 10 and 5%, were inferior to the control peers by 4.4 and 2.2%, respectively, according to the mentioned indicator. Increasing the proportion of methionine relative to lysine by 5 and 10% in compound feed for turkeys at all stages of their growth contributes to a reduction of feed costs per 1 kg of live weight gain by 4.5 and 2.2%, respectively. It is proved that the relationship between the ratio of lysine and methionine in compound feed for young turkeys and its costs per 1 kg of live weight gain is described by a polynomial line with a reliable approximation coefficient R2=1. Correlation analysis shows that there is a reliable (р<0.05) strong inverse relationship between these two indicators (rs= – 0,9). The rate of preservation of poultry in all experimental groups was close (94-96%), however, the probable influence of different ratios of lysine and methionine in compound feed for growing poultry on the rate of its preservation was not established.
Epizotic situation regarding chicken infectious bronchitis virus and bacterial co-infection
Considering the significant variability of the chicken infectious bronchitis virus and the complication of the pathological process due to secondary bacterial infection, which in the complex leads to significant economic losses, the assessment of the epizootic situation of this disease is relevant for the improvement of existing and the introduction of the latest control methods. That is why the aim of the work was to assess the epizootic situation regarding the infectious bronchitis virus in meat and egg poultry farms in some regions of Ukraine, as well as to investigate the impact of infectious bronchitis on the development of secondary bacterial infection. The study was conducted in 2024 at four egg and meat producing poultry farms in Khmelnytskyi, Lviv, Rivne, Chernivtsi, and Odesa regions. Blood serum were collected from broiler chickens at the slaughter period, as well as from laying hens, to assess the level of antibodies against the infectious bronchitis virus. Regarding the results of the serological examination, clinical, and pathomorphological examination, it was performed PCR with subsequent typing of the circulating infectious bronchitis virus. The presence of bacterial co-infection was determined using a routine microbiological examination. 432 samples of blood sera were analyzed. Clinical signs and pathological lesions were found only in 50% of the examined samples. Fibrinous tracheitis and edema, kidney hyperemia were main detected at broiler farms however the kidney atrophy and the formation of follicular constrictions were identified in laying hens. The main histological changes characteristic for the infectious bronchitis virus were atrophy of the ciliated layer of the mucosal epithelium and thickening of the submucosa of the trachea due to lymphocyte-macrophage infiltrates, as well as in the case of infection with variant strains – nephrosis and nephritis. The assessment of the epizootic situation and the significance of the infectious bronchitis virus in the pathological process is possible only with a comprehensive analysis of the results of serological, histological, and molecular biological research, which allows to assess the intensity of immunity, the nature and degree of pathomorphological lesions, as well as to detect the RNA of the pathogen.
Technology for the production of hatching eggs of “Novogen Brown” chickens
Currently in Ukraine, crosses of chickens imported from abroad are used for industrial egg production. The most common crosses are “Lomann Brown”, “Lomann White”, “Hy-Line White”, “Hy-Line Brown”, “Novogen White”, “Novogen Brown” and others. To complete the commercial laying flock, the company uses replacement stock obtained from the parent flock, which is kept in a second-order reproducer. LLC "Slovyans" (Kyiv region) has the status of a second-order reproducer for breeding “Novogen” chickens. In this regard, the aim of the study was to investigate the technology of production of hatching eggs of “Novogen Brown” chickens in the conditions of LLC "Slovyans". Day-old chicks of the parental forms of these crosses are supplied to the farm by the French breeding company “Novogen”. The productivity of chickens of the parent flock of the “Novogen Brown” cross was studied when they were kept in “Salmet” cage batteries. Seven 4-tiered batteries are installed in a room measuring 120x18.2 m (2184 m2), which provides accommodation for 38770 hens and roosters with a sex ratio of 8.6:1. The hens of the parent flock are fed with dry complete feed, with a nutritional value in accordance with “Novogen” recommendations. The content of crude protein and other substances in the feed changes three times during the productive period, depending on the age of the hens. As for crude protein, this indicator tends to decrease. The recommended minimum level of total fiber is 4.0%. The farm uses parent stock up to 72 weeks of age. At the same time, the actual egg production per initial laying hen is almost the same as the standard (298.6 eggs) and amounts to 299.2 and 298.3 eggs. The preservation of chickens in the farm is slightly lower than the recommendations (by 0.9-1.2%), and the feed consumption per egg is higher (by 3.08 and 3.59 g).
The effect of walnut leaves as a substitute for antibiotics on the productivity and safety of chickens
In connection with the introduction of a ban on the use of feed antibiotics in poultry farming in the European Union since 2006, the search for alternative means of preventing poultry diseases is urgent. The effectiveness of the use of walnut leaves in the form of a decoction, alcohol tincture and dry powder in the cultivation of repair young chickens was investigated, and their effect on the growth and development of the bird was evaluated. To carry out the research, day-old chickens of the Birkivska Barvysta Ukrainian selection were randomly divided into 5 similar groups of 60 heads each. All groups were fed standard full-rational compound feed in accordance with the direction of productivity. Chickens of the control group (С) received the basic diet without additives. The birds of the first experimental group (D1) received a synthetic antibiotic with drinking water (according to the manufacturer's instructions for use), the chickens of the second experimental group (D2) had 10% alcohol tincture of walnut leaves added to their drinking water in the amount of 10 ml/l, the third experimental group (D3) – instead of water they drank a 1% decoction of walnut leaves, the fourth research group (D4) – were additionally fed 1% dry ground walnut leaves. The period of action of the supplements is during the first week of rearing young animals, the observation period is 10 weeks. It was established that the studied phyto-additives have a positive effect on the growth and development of chickens, contribute to the improvement of feed absorption. As a result of the application of walnut leaves during the first 7 days of life, its stimulating effect on the bird was noted, the live weight of the chickens during the period of action of the additives in the experimental groups was 0.3-8.3% higher compared to the control counterparts, at the end of the experiment – by 2.8-8.7%. The use of the investigated phyto-additives contributed to the improvement of the average daily growth of chickens by 3.1-9.1%, feed conversion – by 3-8.3%. According to the results of the experiment, among the groups that received walnut leaves in various forms, the best indicators were found in group D2 under the influence of alcohol tincture. The average daily gain of live weight, feed conversion and survival of young animals were similar to the indicators of group D1 after drinking a synthetic antibiotic. This stimulating effect and the confirmed antibacterial activity of the alcoholic tincture of walnut leaves against the background of improving the zootechnical indicators of birds demonstrate the potential of its use for the prevention of bacterial diseases in the first week of rearing of repair young chickens.

Genetic potential of productivity of egg crosses of “Lohmann Breeders GmbH”
Now, crossbred chickens imported from abroad have been used in Ukraine for the industrial production of food eggs. Lohmann Breeders GmbH (Germany) is one of the leading breeding companies specializing in the creation of crosses of laying hens. However, not all crosses of this company are used in poultry farms in Ukraine. It should be taken into account that the genetic potential of poultry productivity is manifested under certain conditions of keeping and feeding. In this regard, the purpose of the research was to analyze the main directions of selection and breeding work in egg poultry farming and to study the productive indicators of modern egg crosses of poultry selected by Lohmann Breeders GmbH. Currently, the company offers the following crosses of chickens for the industrial production of food eggs using classical technology: "Lohmann brownclassic", "Lohmann brown-extra", "Lohmann brown-lite", "Lohmann LSL-classic", "Lohmann LSL-extra", "Lohmann LSL-lite", "Lohmann LSLultra lite", "Lohmann sandy", "Lohmann silver", "Lohmann tradition". By using industrial poultry up to 72 weeks of age, you can get from 317 eggs (cross "Lohmann silver") to 335 (cross "Lohmann LSL-ultra light") for one initial laying hen. In the productive period up to 80 weeks of life, the laying capacity per initial laying hen is 361-381 eggs. "Lohmann LSL-ultra lite" cross of chickens (381 eggs) is characterized by the highest egg production during the specified period. When keeping hens up to 100 weeks of age, their laying capacity is from 442 to 482 eggs. The hens "Lohmann brown extra", "Lohmann LSL-extra" and "Lohmann tradition" have the largest mass of eggs. Hybrid laying hens of all studied crosses have an optimal live weight, which correlates with feed consumption per unit of production. At the same time, hens that lay eggs with a white or cream shell consume 1.9-2.1 kg of feed per 1 kg of egg mass, and 2.0-2.2 kg with a brown shell.
