An experiment has been conducted to determine the effectiveness of growing broiler chickens when whole wheat grain has been included in the compound feed. The purpose of the research was to develop an appropriate scheme and dose for feeding whole wheat grain depending on the age of broilers, while observing the normative content of metabolic energy and nutrients in the diets, and to determine the economic effectiveness of rearing of broilers. To determine the effectiveness, data on live weight, growth rate, livability, uniformity of broiler population by live weight and variability of live weight of chickens have been studied. In the course of the work, the livability, average daily gain, feed conversion, homogeneity and variability coefficients, and the productivity index have been calculated. An increase in the live weight of broilers, as well as the rate of growth in pre-slaughter age when using whole grains in poultry diets, as well as a decrease in feed consumption per unit of live weight gain has been revealed. In conclusion, the economic effectiveness of broiler meat production has determined when whole grain has been included in diets. The use of whole wheat grain as an additive to the main diet in broiler feeding allowed to increase profits and increase the level of profitability. It has been found as a result of research that it is advisable to add whole wheat grain to the main diet for broilers at the age of 8–14 days in an amount of 5 % of the feed weight, at the age of 15–21 days – 15 %, at the age of 22–28 days – 20 %, at the age of 21–29 days – 30 % of grain without reducing the overall nutritional value of the diet.

In order to increase the meat productivity of broiler chickens, increase production volumes and reduce the prime-cost of poultry products, it is necessary not only to ensure balanced feeding and compliance with production technology but also to include in the poultry diet non-traditional additives, biologically active substances that contribute to the normalization of metabolic processes and improve the digestibility of feed nutrients. One of these dietary additives is Betulin extracted from birch bark, which has antioxidant and immunomodulatory properties. In this regard, the purpose of the research was to study the influence of compound feed with the introduction of 2 % feed additive based on a synthetic microspherical nanoporous carbon carrier containing biologically active Betulin in its composition on the productivity of broilers. The results of studies on broiler chickens using compound feed with 2 % feed additive have been presented in the article. It has been found that the feed consumption per 1 kg of live weight gain in poultry of the experimental group have been lower by 9,5 % due to better absorption of nutrients, the live weight of broiler chickens of the experimental group at the age of 42 days was 2625,6 g and it was higher than the control group by 3,68 %. The digestibility of crude protein and fat reached 92,73 and 88,03 %, which exceeded the control group by 1,03 and 3,03 abs.%, respectively. It has been found that the use of compound feed with 2 % of the feed additive with the biologically active substance is of practical importance in connection with the increase in the productivity of broilers and the level of profitability of meat production by 8,2 abs.%.

Effect Of Feeding

The results of the effect of feeding the chelated form of Zinc on the safety, productivity and slaughter parameters of broiler chickens are presented. The aim of this study was to determine the safety, productivity and slaughter parameters of broilers on the background of feeding chelated form of Zinc. Materials and methods. Experimental studies were conducted during 2020 on broiler chickens cross Cobb-500 in the vivarium of the Veterinary Faculty of Sumy National Agrarian University (Ukraine), divided into two groups on the principle of analogues (control and experimental) of 50 broilers each. The source of zinc for chickens in the control group was their sulfates. Chelated forms of Zinc were used for broiler chickens of the experimental group. All groups of broiler chickens were administered the compound with compound feed in a dose that corresponded to the daily requirement of the bird in this trace element. The duration of the experiment is 42 days. The growth and development of broilers were evaluated on the basis of determining the relevant zootechnical indicators. Live weight of birds was determined by individual weighing on scales of the VNC type with an accuracy of ±1 g at the age of 7, 14, 21, 28, 35 and 42 days. Both scientific and economic experiments also determined the preservation of livestock - daily by the number of culled and dead birds. Feed consumption was recorded daily, for each week of cultivation and for the entire period of the experiment. At the end of the experiment, the cost of feed per 1 kg of live gained weight was calculated. Results. According to the results of the conducted researches, it was established that feeding of the chelated form of Zinc probably increased both the average daily gain and the total live weight of broiler chickens at different age periods of rearing. The live weight of chickens at the beginning of the experiment was almost the same, but at 7 days of age it tended to increase in chickens of the experimental group, although a significant difference between groups in this indicator was not found. It was found that the weight of uneviscerated, semi-eviscerated and eviscerated chicken in poultry of the experimental group was greater than similar indicators in the young animals of the control group by 9.3, 9.2, and 9.8 %, and this difference was significant (p<0.01). The yield of semi-eviscerated carcasses was higher in ones of the experimental group (84.19 %), and the difference was significant (p<0.05). Conclusions. It was found that the live weight of chickens of the experimental group (consumption of feed with a chelated form of Zinc) prevailed at 7 days of age by 1.1 g; on the 14th day – on 22.1 g (p<0.01); at 21 days – 35.4 g (p<0.01); at 28 days – 94.5 g (p<0.05); at 35 days – 133.6 g (p<0.01); at 42 days – at 218.9 g (p<0.05). Preservation of young animals in the experimental group, which used chelated compounds of Zinc, was higher and amounted to 96 %, compared with the control – 92 %. By age, feed costs per unit weight gain were lower in the experiment, respectively: 0.05; 0.08; 0.12; 0.06; 0.07 and 0.05 kg, compared to the control group. Growing broiler chickens on compound feed with a chelated form of Zinc by 9.8 % (p<0.01) increases the weight of the eviscerated carcass.

The authors studied productivity and product quality under industrial poultry production technology. The productivity of broiler chickens of Ross-308 and Hubbard Iza-F-15 was different during floor rearing. Broiler chickens of Ross-308 outperformed Iza-F-15 chickens in body weight and average daily gain. The live weight at the slaughter of Ross-308 chickens was 2,360 g. The live weight of the chickens of Iza-F-15 was 2088 g. The conversion of feed to produce was higher in the chickens of Ross-308 cross by 0,06 kg compared with the chickens of Iza-F-15 and amounted to 1.64 kg per 1 kg of live weight gain. The survival rate was high for Ross-308 chickens (95.8%). The safety of the flock of the Izu-F-15 chickens was 2.2 per cent lower and was 93.6 per cent. Slaughter yield in the chickens cross Ross-308 is higher than in the group of chickens cross Iza-F-15. Meat quality is also better in Ross-308 chickens. Growing broiler chickens of Ross-308 cross for meat under industrial technology allowed to get more profit compared to the use of poultry of Iza-F-15 cross. At the exact cost of feed, 1 kg of live weight gain was 7.1 roubles, and per 1 head of chick was 19.1 roubles. The profitability level is also 12.6% higher for the broiler chickens of Ross-308 cross. The cumulative indicator the European productivity index is higher for chickens of Ross-308 breed, compared with chickens of Iza-F-15 breed on 56 units. This index was 341 and 285, respectively.

New Phase

A new phase system of feeding pheasants at their intensive rearing for meat, enhanced by factors of amino acid and energy influence on the young poultry growth rate into account its feeding preferences has been developed and allowing to obtain the live weight of pheasants at the age of 17 weeks at the level of 900 g and more. With the use of this system the yield of gutted carcass of pheasant reaches 60–61 % of the pre-slaughter weight with a sufficiently high specific weight of valuable parts-breast (40–42 %) and legs (29–30 %). In the proposed system of poultry feeding the same type of corn grain component of compound feed is more effective when it is 55 % by weight,. The experimental data confirm that the corn type of feeding pheasants intensively reared for meat, contributes to the activation of feeding behavior of young poultry. At the same time, the total time of feed consumption by poultry per head in comparison with the use of a set grain feeds (wheat – 15 %, barley – 11 %, corn – 31 %, peas – 8 % by weight) significantly increases by 12–13 minutes per day. The increase in feed activity is one of the factors allowing to increase the live weight at 17 weeks by 112,9 g or 14.5 % (P < 0,001) and the weight of pheasant legs after slaughter by 20,0 g or 14,7 % (P < 0,05). At the same time feed expenditures per 100 g of growth are reduced: dry matter by 0,12 kg (22,2 %), metabolic energy by 1,51 MJ or 20,8 %, and raw protein by 0,03 kg or 25 %. The preferential use of corn for fattening makes it possible to reduce the sale price of young poultry of meat purpose in live weight by 53–54 rubles or 15–16 %, and in the form of gutted carcass by 58–59 rubles or 9,5–10,0 %, which increases the effectiveness of pheasant meat production technology.

It has been established that eimeriosis intensively infects chickens aged from 7 days to three months with floor keeping, unbalanced monotonous feeding, a decrease of the general resistance of the organism and crowded housing, coccidiosis is difficult and is accompanied by a large mortality of birds. Despite the large number of methods and means of preventing of this disease in poultry farms of Dagestan Republic bird eimeriosis is widespread and causes significant economic damage to poultry farms and personal subsidiary farms of citizens. In this regard, the search and use of available anti-eimer drugs in combination with probiotics with immunochemical prophylaxis properties that meet modern requirements is a very urgent task. To study the effectiveness of therapy of eimeriosis in broiler birds, the drug Eimeterm was used in combination with the probiotic vet. It was found that eimeterm-2.5% ih dose 1 ml per 1 liter of water during 48 hours in combination with Vet 1.1.in dose 75 mg / kg, twice a day, during 7 days with feed, in eimeriosis of chickens - broilers has a pronounced anti-eimer effect, the effectiveness of the drugs - 98.2%. The combination of the schemes used contributed to the reduction of mortality from 7 to 1 head from 11.2 to 4.0%, i.e. exceeded 6.74 times, the effectiveness of treatment. Feed consumption of 1 kg of live weight gain in the control and experimental groups was 2.3 and 1.4 kg, respectively, which significantly reduces the cost of production. The average live weight of one chicken of the end of the experiment in the control and experimental groups -1710, 2040 g, respectively, or on 330 g (16.1%) more, than the chickens in the control . The productivity index in the first group - 72.60, in the experimental group, 265.0 points, which is on 3.65% higher than in the control.

It is known that necessary to replace the components of organic acids, which are part of acidifiers when drinking water to poultry in order to prevent the adaptation of microbes in the gastrointestinal tract. In the poultry industry organic acids are widely used, which are used as acidifiers to preserve the properties of water consumed. The purpose of this work was to evaluate the efficiency of broiler meat production when using acidifying agents of drinking water Aquasafe and Veleguard. The experimental part of the work has been performed in JSC “Kurinoe Tsarstvo-Bryansk” broiler area “Roshcha” in the Pochepsky district. The object of research was the livestock of broiler chickens cross Cobb 500 at floor housing. The effect of water acidifiers on meat productivity has been studied. Groups of chickens have been formed on the principle of pairs-analogues. Broiler chickens of experimental groups have been separated from the main livestock by a grid in the corner of the room for 100 heads in each group. It has been found by a result of research to be optimal dose usage of acidifying agents water Aquasafe and Veleguard to drink to broiler chickens. The positive effect of these acidifiers on the digestion of crude protein, crude fat, crude fiber, contributing to the effective use of nitrogen, which led to an increase in the intensity of growth, young animals’ livability and improved feed conversion. Slaughter yield in the control group was 55,1 %, and in the experimental group 57,2 and 58,4 %, which was by 2,1 and 3,3 % higher with the same level of metabolic energy and nutrients. In chickens that consumed acidifi ers more intensively used nutrients feed for deposition in the body of the components of the carcass, which affected the production. A positive impact of acidifying agents Aquasafe and Veleguard on meat quality in broiler chickens has been found.

The aim of this research was the visual characterization and investigating the effects of Alternaria spp. contaminated wheat grains in the starter stage of broilers nutrition on productive parameters and oxidative stress. The research was divided into two phases. Bunches of wheat in post-harvest period of year 2020 was collected from a various locality in Serbia and Albania. In the first phase, collected samples were visual characterized by Alternaria spp. presence by color measurement methods. Gained results are conferred in the range of the color properties of grain color properties of Alternaria toxins. Wheat grain samples were significantly different (p < 0.05) in terms of all measured color parameters (L*, a*, b*). Classification of field fungi in analyzed wheat grain samples showed that the significant field fungi were Rhizopus spp., followed by Alternaria spp., and Fusarium spp. In the second phase, biological tests with chickens were carried out during the broiler chickens’ dietary starter period in the first 14th days of age. At the beginning of the experiment, a total of 180-day-old Ross 308 strain broilers were equally distributed into three dietary treatments, with four replicates each. Dietary treatments in the experiments were as follows: basal diet without visual contamination of Alternaria spp. with 25% wheat (A1), a basal diet with visual contamination of Alternaria spp. with 25% wheat from Serbia (A2), basal diet with visual contamination of Alternaria spp. with 25% wheat from Albania (A3). The trial with chickens lasted for 14 days. After the first experimental week, wheat infected with Alternaria spp. in treatment A2 and A3 expressed adverse effects. The highest body weight of chickens of 140.40 g was recorded in broilers on control treatment A1 with statistically significant differences (p < 0.05) compared to treatments A2 (137.32 g) and A3 (135.35 g). At the end of the second week of test period, a statistically significant (p < 0.05) difference in body weight of broiler chickens could be noticed. The highest body weight of 352.68 g was recorded in control treatment A1, with statistically significant differences compared to other Alternaria spp. treatments. The lowest body weight of chickens was recorded in treatment A3 (335.93 g). Results of feed consumption and feed conversion ratio showed some numerical differences between treatments but without any statistically significant differences (p > 0.05). Alternaria spp. contaminated diet increased glutathione (GSH), glutathione reductase (GR), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) and decreased peroxidase (POD) and superoxide dismutase (SOD) serum levels, respectively. Built on the achieved results, it can be concluded that the wheat contaminated with Alternaria spp. in broilers nutrition negatively affected growth, decreased oxidative protection and interrupted chicken welfare in the first period of life.

Own performance traits of boars were average daily gain (ADG) from birth to 100 kg live weight, backfat thickness (BF) and lean meat content (LMC) in field conditions. Progeny of boars was housed in pairs (gilt and barrow) and fed standardized feed mixture semi ad libitum. Progeny test lasted from 30 to 100 kg live weight. There were evaluated following parameters: ADG and feed consumption/kg gain (FC) at test from 30 to 100 kg live weight, slaughter weight (SW), proportion of meaty cuts (PMC) proportion of ham (PHAM), eye muscle area (EMA), and BF. At Bucany and Nitra was found the effect of genotype of boars on progeny BF and/or FC respectively. Better tested boars from own performance test individually as well as a group achieved in progeny better fattening and carcass traits than worse tested boars at Bucany (+33 g ADG, -0.21 cm BF, +2.34 % PMC). Progeny performance from better evaluated boars at Nitra did not exceed the progeny performance from worse tested boars. There was found significant effect of dams on progeny performance.

UTILIZATION OF “GEDI LEAF (Abelmoschus Manihot (L) Medik) AS“ADDITIVE” IN DRINKING WATER RELATED TO THE PERFORMANCE OF INDONESIAN SUPER NATIVE CHICKEN. Research was done to evaluate the performance of Indonesian super native chicken treated with “Gedi” leaf (Abelmoschus Manihot (L) Medik) as“Additive” in drinking water. Study was conducted using hundred individuals of the Indonesian super native day old chicken. The juice of “Gedi” leaf (Abelmoschus Manihot (L) Medik) was given as in forms of the four treatments as follows, drinking water without “Gedi” leaf as control (P0), drinking water with 10 ml juice of “Gedi” leaf per liter of drinking water (P1), drinking water with 20 ml juice of “Gedi” leaf per liter of drinking water (P2), and drinking water with 30 ml juice of “Gedi” leaf per liter of drinking water (P3). Treatments were applied to the birds at 6 weeks old by completely randomized design five replications at each treatment. Data were taken during 5 weeks. Feeds were using 73 percents of commercial feed added by 10 percents of corn and 17 percents of rice bran with nutritional composition of crude protein 19.49 percents, crude fiber 4.66 percents, fat 3.63 percents, Calcium 1.02 percents, Phosphorus 0.66 percents and metabolic energy of 2920 kcal/kg, all given ad libitum. Variables measurement were focused on feed consumption, drinking water consumption, average daily gain, and feed conversion. Results showed that drinking water with 30 ml juice of “Gedi” leaf per liter of drinking water (P3) was not significantly different with other treatments for feed and drinking water consumption, except for average daily gain and feed conversion. The treatments of P1 and P2 were not significantly different for average daily gain, but these treatments were higher in average daily gain compared with control (P0). The highest value of feed conversion was obtained at treatment P3 and the lowest value was found at treatment P1. These values indicated that the best feed conversion was treatment P1. Therefore, it can be concluded that juice of “Gedi” leaf can be used as the alternative additive feed in drinking water up to 20 ml juice of “Gedi” leaf per liter of drinking water in term of high average daily gain and feed conversion of Indonesian super native chicken. Key words: Drinking water, “Gedi” leaf, Indonesian super native chicken.

A comparative assessment of the fattening qualities of rabbits of different breeds on a farm with an intensive technology of rabbit meat production was carried. The material for the study was a herd of rabbits of meat and skin breeds: Gray Giant Flander, Californian, Silver Fox. The experiment was carried by the group method. For this purpose, 30 rabbits were selected at 45 days of age and 3 groups of 10 heads were formed. Analogue rabbits were selected by breed, age, live weight, sex. The experimental livestock was housed in a shed-type room equipped with 4 rows of mesh cages arranged in two tiers, in which bunker feeders and nipple drinking bowls were installed. The animals were fed with pellets compound feed with the addition of leguminous Herbal hay. Compound feed was distributed from bunker self-feeders, Herbal hay – from feeders (mangers). The rabbits were watered from nipple drinkers, which provided the animals with constant access to food and water. In the course of the research, the live weight of rabbits, absolute and average daily gain, relative growth rate and feed costs were studied. It has been found that the Californian rabbits fulfill their growth potential better than the Silver Fox and Gray Giant Flander rabbits. Average daily gains in rabbits of the Californian breed were 1.8 g higher compared to analogs of the Silver Fox breed and 1.18 g higher than in the Gray Giant Flander. In terms of live weight, at the end of the experiment, the Californian rabbits were dominated by analogs of the Silver Fox breed by 116.7 g and by 90 g of Gray Giant Flander rabbits. The level of profitability of raising young rabbits for meat of the Californian breed was 12.2 %, and the Gray Giant Flander and Silver Fox breeds, respectively – 3.8 and 4.0 %. Key words: fattening qualities, Gray Giant Flander, Silver Foxy breed, Californian breed, average daily gains, economic efficiency.
