The effect of dietary supplementation of selenium in an organic form on performance, carcass traits and selenium content in tissues of broiler cockerels Ross 308 was studied. The soya-wheat-maize diet contained 50 mg vitamin E/kg. The experiment was conducted on 810 straight-run broiler cockerels randomly divided into 3 groups: group I – control, without selenium supplement; experimental group: II – 0.3 mg Se/kg, Se-enriched yeast was applied as a Se source; III – 0.3 mg Se/kg, Se-enriched alga Chlorella as a Se source. The broiler chickens were slaughtered at 42 days of age. In performance traits higher (P ≤ 0.05) live weight of broiler chickens was recorded in the experimental groups (II – 2 430.6 g and III – 2 425.2 g). There were no significant differences between the groups in feed conversion and mortality. Se-enriched alga had the best feed conversion, and selenium supplementation slightly increased mortality in both experimental groups. No significant differences between the groups were found out in carcass traits and dressing percentage. The content of selenium in breast and thigh muscle, feathers and excrements increased (P ≤ 0.05) in both experimental groups compared to the control group. Higher values in breast and thigh muscle and in feathers were measured in the group supplemented with selenium from Se-enriched yeast, also in comparison with the group supplemented with selenium from Se-enriched alga Chlorella. The broiler chickens receiving Chlorella had a higher (P ≤ 0.05) selenium content in excrements compared to the group with Se-enriched yeast. The selenium concentration in liver was higher (P ≤ 0.05) in both experimental groups compared to the control. The supplement of selenium from Se-yeast and Chlorella in the diet for broiler chickens increased the microelement concentration in muscle.

Combined Feed

Introduction. In recent years, the production of feed additives of animal origin in Ukraine has declined sharply, and the cost of imported additives is very high. At the same time, in our country, the industry of industrial poultry farming has recently received intensive development, in particular, the cultivation and processing of broiler chickens for meat. At the same time, a significant amount of non-food waste from poultry slaughter in many poultry farms is not processed for feed purposes. Currently, an urgent problem is the organization of processing of non-food waste of poultry for feed purposes at poultry farms of industrial type of cultivation for meat of broiler chickens, primarily from blood and hydrolyzed raw materials. Processing of these wastes for feed purposes will not only give the opportunity to increase the production of high-grade protein feed, but also to significantly improve environmental safety. The purpose of our research is to study the meat productivity, safety, slaughter yield and quality of broiler chicken meat when feeding a combined feed additive from blood and hydrolyzed raw materials. Materials and methods of research. Development of an innovative technological line for the production of a combined feed additive from blood and hydrolyzed raw materials was carried out in LLC "Complex Agromars" (village of Havrylivka, Vyshgorod district of Kyiv region), and research on the effectiveness of feeding a combined feed additive from blood and hydrolyzed raw materials was performed in the production conditions of LLC "Bila Hora" Sniatynskyi district of Ivano-Frankivsk region. Research result. Development of innovative technological line was carried out in cooperation with engineering and technical staff of LLC "Complex Agromars". The innovative technological line is designed and installed using devices and mechanisms of the company "Haarslev Industries". In order to study the effectiveness of feeding a combined blood-feather feed additive for the experiment, four groups of broiler chickens of the Cobb 500 cross were formed, 50 heads in each, according to the following scheme: one group of broiler chickens was taken as a control group, and the next three groups – as research groups. Cultivation of broiler chickens in the experiment was carried out according to the traditional technology of feeding on standard compound feeds adopted in industrial broiler poultry farming, which, depending on the age and growth of chickens, includes 3 phases: "Start" – 14 days, "Growth" – 18 days, "Finish" – 12 days. According to the scheme of experience, the control group of chickens received standard feed without blood-feather feed additive. The difference in feeding of the broiler chickens of the experimental groups was in different levels of feeding with experimental combined feed additive from blood and hydrolyzed feather raw materials, which, depending on the age and growth of chickens, included in the feed of the I group from 4 to 12%, of the II group – from 3 to 10%, of the III group – from 2 to 8%. As a result of the studies it was found that at the end of the experiment at 44-day age the average live weight of broiler chickens of the control group was 2630 g, of the experimental group I – 2885 g, of the group II –2790 g, of the group III – 2680 g. For 44 days of experience the following amounts died: in the control group – 2 chickens, in the experimental group I – 1 chicken, in the group II – no chickens, in the group III – 1 chicken. Slaughter of broiler chickens and meat tasting was carried out in the company "Bilyi Bereh" of Ternopil region at the age of 44 days. It was established that the average slaughter yield of 1 carcass of broiler chicken meat was: in the control group – 1920, in the experimental group I – 2106 g, in the group II – 2037 g, in the group III – 1956 g. The difference in quality of meat of broiler chickens of control and experimental groups by results of tasting was not revealed. Summary: In LLC "Complex Agromars" (village of Havrylivka, Vyshgorod district of Kyiv region) designed and implemented an innovative technological line for production of ecologically safe combined feed additive from blood and hydrolyzed feather raw materials from non-food waste slaughter of broiler chickens when growing for meat. In the course of scientific and economic experiment it was found that the inclusion in the standard traditional feed in different phases of cultivation of broiler chickens for meat of about 4 to 12% of the combined feed additive from blood and hydrolyzed feather raw materials increased their average live weight from 2630g in the control group to 2885 g, and the average slaughter yield of 1 meat carcass – from 1920 g in the control group to 2106 g.

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.

The objective of our study was to test amaranth grain or dried biomass in the diet for broiler chickens as a resource of protein replacing animal protein. Further, the effect of amaranth on broiler performance, carcass characteristics and meat quality were assessed in a feeding trial. The experimental groups of broilers were fed feed mixtures with crude amaranth grain (AC), heat processed amaranth grain (AP) or dried above-ground biomass (AB). Control groups (C) received the diet containing animal proteins. The results obtained in the experimental groups of broiler chickens can be compared to the control group in all the production indicators under investigation. On day 42 of the experiment, live weight (g) of female broilers ranged from 2 205.1 ± 152.5 (AP) to 2 254.0 ± 136.5 (C), and that of male broilers from 2 375.1 ± 233.0 (AC) to 2 506.0 ± 286.0 (C). Feed conversion ranged from 1.80 kg in control group of male broiler chickens to 1.91 kg in experimental group of male broilers (AB). Percentage yield in female broiler chickens ranged from 70.8 ± 1.74 (AB) to 72.4 ±3.34(AC) or 72.4 ± 1.98 (C), and in male broilers from 72.8 ±3.55(AP) to 75.1 ±2.44(AB). Our results showed that amaranth can fully replace meat-and-bone meals in the diets for broiler chickens.

The purpose of research is increase of beef productivity and beef quality of Simmental calves at introduc-tion in a diet of feeding different doses of the drug Vetosporin suspension. Of the half-yearly animals, 40 males were selected and formed into group IV for the experiment. The differences were only in feeding. The young were fed the studied additive Vetosporin suspension. In this case, the supplement was an addi-tion to the basic diet of animals of the experimental II-IV groups. The volume of the additive added was 0.1; 1.0; and 2 ml per 10 kg of live weight, respectively. Control group I, consumed exclusively a diet that does not contain an additive. Based on the results of the experiment at the age of 18 months. The prevalence of bulls of the experimental live weight over peers was observed, which was 4.4-25.3 kg (0.78-4.67%). The study of the studied indicators after control slaughter in the context of groups showed the superiority of bulls of experimental groups in all the periods studied. It is established that at the age of 15 months. The size of the removable live weight of the youngest of the control group was less by 8.0-19.7 kg (1.75-4.29%) than in the animals of the test groups. In this case, the leading position was occupied by the youngest of group III, the prevalence of which was 0.7-11.7 (0.14 -2.51%). It should be noted that after 3 months a simi-lar picture of the distribution of the studied quantities was observed. As for the output of carcass, we can note the following. Outsider among the animals of the experimental groups was the control group. So the bulls of group I were inferior to those who received the additive by 0.7-1.3%. At 18 months, as well as at 15 months, the dominant position was occupied by gobies of experimental groups. It should be noted that among the animals of the experimental groups the leading place was occupied by the bulls receiving the feed additive in a dose of 1.0 ml per 10 kg of live weight, that is, the youngest of the III group.

Ad Libitum

Two hundred and twenty five day old straight run broiler chicks were utilized in completely randomized design to test the effect of restricting feed intake of four groups of chicks to 92.5% 85.0%, 77.5% and 70.0% of the unrestricted (control) group in the starter phase and following adlibitum feeding for all groups in the finisher phase. The treatments were simply designated as A, B, C, D and E. The starter phase in which the restriction was carried out lasted 28 days and the finisher phase 42 days. Parameters evaluated during the starter and finisher phases included; growth rate, feed conversion ration and mortality rate. Results show gain in weight among all groups while the group fed diet B and the control had comparable weight gain at the starter phase. The percentage weight difference between the control and each of the other dietary groups was: 4.4%, 8.4%, 8.6% and 10.4% for the treatments B, C, D and E respectively. Feed gain ration improved as the level of restriction became stricter. Following ad-libitum feeding of all grops at the finisher phase, the feed restricted groups at the starter phase voraciously increased their feed intake, thus, producing comparable performance values with the unrestricted (control) group in weight gain in the 8th week of the study. Although birds in all groups averaged more than 2000g final live weight in 10weeks, significant differences exist between groups that were fed diets C, D, and E that were restricted at the starter phase, an indication that complete compensatory growth was not obtainable. Feed gain ration improved for restricted groups. Mortality rate did not show any trend attributable to levels of feed restriction. This study shows that broiler chicks fed restricted levels of balanced diet at the starter phase but later fed ad-libitum at the finisher phase could attain a finished weight of about 2000g or more at a market age of 10 weeks (70 days) with an improvement in feed gain ration.

Overall Mortality

As an alternative to feed antibiotics for saving poultry livestock and increasing productivity the acidifiers based on organic and inorganic acids are used more and more frequently. The article represents the results of study of effectiveness of Fidacid acidifier usage for breeding broiler chickens. The study has been conducted on two groups of broiler chickens of Ross 308 breed. The chickens of the experimental group except the full feed–stuff have been given the acidifier at a rate of 1 liter per 1 ton of water. The watering has been carried out from the 27th day of feeding for 10 days (27 – 31 and 34 – 38 days). It has been established that the acidifier watering from the 27th day of breeding chickens has contributed to the increase of preservation of livestock in 4.6%. The overall mortality of chickens has decreased in 2 times (P ≤ 0,001) and amounted to 4.3%, with the permissible limit up to 5%. It has been found that the application of the acidifier has promoted the economy of feed at higher productive indices. There has been a decrease in cost of feed per 1 head in 8.7% (P ≤ 0,01) and a decrease in feed conversion in the experimental group in 0.19 units. This is the evidence of better digestibility of feed and its taking by the bodies of chickens. The live weight of broiler chickens of the experimental group on the 43rd day of breeding increased in 47 grams and carcass weight increased in 30 grams, that is in 1.8% and 1.6% (P ≤ 0,01), respectively. The European index of efficiency in the experimental group has been 56.5 units higher than in the control group of chickens.

The poultry industry in Russia has significant prospects for the development of domestic production of eggs and poultry meat. Insufficient attention is paid to the practical application of enzyme drugs, although numerous studies have proven the effectiveness of these substances in feeding animals and poultry. The purpose of the research was to determine the feasibility and effectiveness of using the multi-enzyme drug Axtra XAP 101 produced by DuPont as part of compound feed for growing broiler chickens. A scientific and economic experiment has been carried out and various doses of the multi-enzyme drug Axtra XAP 101 have been experimentally studied as part of compound feed and the optimal dose in the amount of 7–9 % of the dry matter of the compound feed has been identified. Multi-enzyme drug Axtra XAP 101 influences on indices of meat productivity of broiler chickens. It has been found that this drug increases the average daily increase in live weight of broiler chickens, reduces feed conversion and has a positive effect on the livability of livestock. The highest value for livestock livability has been observed in the 3rd experimental group, where it was 97,67 %, which was by 0,32 % higher than in the control group, by 0,5 % higher than in the 1st experimental group and by 0,57 % higher than in the 2nd experimental group. The European productivity index was the highest in the 3rd experimental group and amounted to 412 points. This indicator was higher than in other groups: higher than the control group by 20 points, the 1st experimental group – by 12 points, the 2nd experimental group – by 5 points. Thus, the effect of using enzymes in wheat and barley diets is to increase and equalize the nutritional value of different varieties and batches of grain. Changing the location and mechanism of microbial fermentation as a result of adding an enzyme also has a positive effect on the health of poultry.

The effects of an exogenous emulsifier, glyceryl polyethylene glycol ricinoleate, on performance and carcass traits of broiler chickens were assessed. The emulsifier was added to the diet at dose rates of 0 (control), 1 (E1) and 2 (E2) % of added fat (saturated palm oil). Live weight gain () and feed conversion ratio () in 39 days were higher in the E1 dietary group. Gain: ME intake and gain: protein intake during the grower phase improved quadratically (). Gross carcass traits were not affected. Body fat content and fat accretion increased () and liver fat content decreased () linearly with the level of emulsifier in diet. Fat excretion decreased () leading to increased ileal fat digestibility () in the E1 group (quadratic response). Metabolizable intake of N () and fat () increased quadratically due to supplementation of emulsifier in diet. Metabolism of trace elements and serum lipid profiles were not affected. The study revealed that supplementation of exogenous emulsifiers in diets containing moderate quantities of added vegetable fats may substantially improve broiler performance.

A study of the effectiveness of the use of feed additive Liaform in relation to its effect on the growth and development of broiler chickens. For research, 2 groups of broiler chickens of 55 heads (control and experimental) from 8 days of age were formed on the principle of analogues. Feeding of the control group was carried out with standard complete feed. Feeding of the experimental group was carried out with standard complete feed, in which the feed additive Liaform was added at the rate of 2 g / kg. During the experiment, the general condition of the bird, the safety of the bird, zootechnical and hematological parameters were monitored. It is established that the studied feed additive has a positive effect on the productivity of broiler chickens, improves feed absorption. As a result of the use of feed additive Liaform live weight of broiler chickens in the experimental group was 4.3 % higher compared to the control. The average daily gain of chickens in the experimental group exceeded this figure of chickens in the control group by 4,1 %. The use of feed additives helped to increase feed conversion. The use of Liaform feed increased the protein level in poultry meat

The Stability

The paper presents the effects of temperature and feed composition on the stability of lipids in breast and thigh muscles of COBB 500 meat hybrids. The chickens were reared in accordance with the technological procedure. The diet of experimental groups contained Proenergol in combination with Energol; the diet of control group chickens contained Proenergol and soybean oil. In the control groups and in half of the experimental groups, the temperature was reduced in agreement with the technological procedure, while it was kept at the constant level of 31 °C in other groups. The feeding continued up to the age of 42 days. The level of lipid oxidation was determined using malondialdehyde assays. No differences between individual groups of chickens were found in the breast muscle. In the thigh muscle, the introduction of Energol resulted in non-significant differences between the control and chickens kept in heat stress conditions. Negative correlation between lipid oxidation and live weight was established in control chickens fed soybean oil (p < 0.05). This correlation was positive (p < 0.05) in young male chicks fed Energol and kept at constantly increased temperature.
