The Impact

The paper demonstrates the results of applying some doses of probiotic specimen “Propionovyy” when feeding broilers. Propionovyy specimen was developed by the staff of the Laboratory of Microbiology of the department “Siberian Research Institute of Chemistry” of Federal Altai Center of Agricultural Biotechnologies. It includes multi strain propionate of Propionibacterium freudenreichii type taken from the Siberian collection of microorganisms. The scientific and economic experiment was conducted at the poultry farm of LLC Kuzbass Broiler in the Kemerovo region. The researchers arranged four groups of broiler chickens; each group contained 198 broilers. The control group received a basic diet without probiotics. In the experimental groups, different dosages of Propionovyy specimen were added to the main diet instead of feed antibiotic. The experiment explores the effect of “Propionovyy” specimen on livestock farming and physiological parameters of broiler chickens. The following indicators were considered: live weight, absolute and average daily gain of live weight, poultry liveability, feed costs per 1 kg of gain, morphological and biochemical indicators of blood at the age of 28 and 39 days. The researchers observed the chickens of experimental groups who received probiotic specimen “Propionovyy” and found out an increase in live weight by 0.49-1.94%, an absolute and average daily increase of up to 2.00%. The safety of the chickens receiving the probiotic was increased by 1.00-2.02% compared to the control group. Hematological parameters of blood in chickens of all groups varied within the limits of physiological standard that testifies to the healthy physiological condition of the poultry. The authors found out the decrease of glucose and cholesterol concentration in blood serum in the experimental groups. According to the research results the authors elaborated the appropriate and efficient dosage of “Propionovyy” specimen, rendering the greatest positive effect on productive qualities of poultry and reducing expenses of forages on 1 kg of growth on 0,05 kg.

Studies were conducted on the use of oil obtained from rapeseed cultivar 'Podmoskovnyj' selection of Federal Williams Research Center of Forage Production and Agroecology in feeding broiler chickens. The experiments were carried out on chickens cross-country "ROSS-308". They were grown in a cell battery. For the experiment, 5 groups were formed. In the start and finish periods, the control group received 2.5 and 3.3% sunflower oil. In the experimental groups, sunflower oil was replaced with rapeseed in the following amounts: the first — 1.0 and 1.0%, the second — 1.5 and 1.7%, the third — 2.0 and 2.5% and the fourth — 2.5 and 3.3%. Feeding was carried out with dry loose feed from a day old. Studies have found that rapeseed oil had less saturated and polyunsaturated fatty acids, but more unsaturated fatty acids. The amount of erucic acid was 0.20%. The digestibility of nutrients was high and practically did not differ from the control variant, as was the use of nitrogen. The inclusion of rapeseed oil in the composition of feed for broilers did not have a significant impact on the increase in live weight and feed costs. The cost of feed with increasing rapeseed oil in their composition decreased, and the efficiency of converting feed into products increased slightly. Compound feeds with rapeseed oil were not inferior in terms of the efficiency of using compound feed containing sunflower oil.

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.

Aimed to study the effective use of different doses of cuprum proteinate in the diet of broiler chickens, three groups of animals were formed with 50 chicks in each. Chickens from the 1st control group received cuprum sulphate as a part of compound feed, and animals from the 2nd and 3rd experimental groups received cuprum proteinate. The concentration of Cuprum in the feed in the 1st and 2nd groups was identical, and in the 3rd experimental group the amount of Cuprum was reduced by 25% compared to the control. During scientific and economic experiment, it was found that the replacement of cuprum sulphate with its proteinate with the same concentration in the feed has a positive effect on the average daily gain of broiler chickens, and therefore a live weight. Thus, the animals from the 2nd experimental group exceeded control analogues by 7.5% in average daily gain and by 9.4% in body mass at the end of the experiment. Reducing the concentration of Cuprum in the feed of chickens from the 3rd experimental group by 25% (the source of the microelement is cuprum proteinate) compared to the control also had a positive effect on the productivity of these animals. They exceeded control analogues in terms of average daily weight gain by 3.8%, and in terms of live weight by 5.8%. At the same time the direct correlation between animal productivity and quantity of the consumed feed was noted. Thus, broilers from the 2nd experimental group consumed more feed by 3.3% compared to control peers. The chickens from the 3rd experimental group exceeded controls by 1.5% in this index. Thus, cuprum proteinate is a more efficient source of Cuprum for broiler feed. The concentration of this microelement in the feed of these animals aged 5-21 days should be 18.2 g/t, 22–35 days - 16.8 g/t, 36–42 days - 12 g/t or 16.5 g/t on average during the experiment.

This study evaluated the effect of two concentrate supplementation strategies on performance, metabolic profile and economic evaluation of suckling lambs and ewes in ryegrass (Lolium multiflorum) pasture. Twenty-seven ewes and 45 lambs were divided into three groups: (1) ryegrass pasture without supplementation - control (CON); (2) CON plus supplemented ewes and lambs at 1% of live weight (SEL), and (3) CON plus creep feeding supplemented lambs at 1% of live weight (CSL). Concentrate use increased (p<0.05) average daily gain (ADG) by 19.95% over CON (21.6 and 18.3% for SEL and CSL, respectively). Concentrate use contributed to minimizing forage quality fluctuation and provided greater ADG stability, mainly when ryegrass nutritional content and digestibility decreased. Blood metabolites profiles did not differ between groups, with exception of phosphorus which was higher for CON than SEL, and calcium which was higher for CSL than CON (p<0.05). Compared to CON, stoking rate values were greater to SEL (p<0.05). Compared to CSL, ewe and total stocking rate were greater (p<0.05) to SEL. Considering the control group as break even feed investment, SEL strategy had a positive economic return, while CSL showed economic losses. Concentrate use increased ADG of lambs and decrease the impact of nutrient quality changes of forage on daily gains, but must be considered that supplemental strategy used could affect negatively economic return.

Poultry Farming

The intensifi cation of modern industrial poultry farming as the most progressive and dynamically developing branch of agriculture aimed at raising productivity and increasing production volumes, inevitably leads to numerous problems related to poultry health. One of the most common ways to solve this problem is to use antibacterial drugs. The results of scientifi c and economic experiment on the use of the phytobiotic additive “Farmatan VSO (Butitan)” in feeding broiler chickens of cross Cobb-500 have been provided in the article. The inclusion in the poultry diet of the phytobiotic “Farmatan VSO (Butitan)” in the amount for compound feed Start 800 g/t, Growth and Finish – 400 g/t leads to increase in the live weight of broilers by 3,0 % compared to the control group. At the same time the average daily gain of live weight in the 4th experimental group was 73 g, which was by 2,8 % more than in the control group. The use of phytobiotic additives in the feeding of broiler chickens contributes to the highest livability of poultry (98,1 %). It has been found that the best indicators for feed expenditures have been noted in the 3rd and 4th experimental groups 1,47 and 1,48 kg, which were 3,3 and 2,6 % lower than in the control group. Thus, the authors have found that the highest live weight, average daily gain, livability and lowest expenditures of feed per unit of production diff ered in broiler chickens of 4th experimental group where in the compound feed antibiotic Flavomycin has been replaced on phytobiotic feed additive “Farmatan VSO (Butican)” in the compound feed Start 800 g/t, Growth and Finish- 400 g/t. Production testing of the use of “Farmatan VSO (Butitan)” has shown the high eff ectiveness of phytobiotics as a mean of replacing the feed antibiotic and improving the livestock indicators of broiler chickens rearing.

Improving the efficiency of pig farming requires biologically complete feeding in accordance with the age, physiological and sexual characteristics of animals based on the knowledge of composition and nutritional value. The health and productivity of animals depends on the use of protein, fat, carbohydrates and minerals, and high-quality vitamins. Traditional feed does not provide animals with a sufficient and optimal ratio of minerals and vitamins. One of the factors providing young pigs with these nutrients may be the inclusion of the DKB vitamin-mineral energy supplement in the diet. The article analyzes the influence of DKB on the productivity of young pigs. The aim of the study was to justify an increase in productivity indicators of large white pigs feeding with DKB. In order to trace the impact of DKB on the productivity of pigs, we took into account the change in their live weight. During the experiment (60 days), 54 kg of the vitamin-mineral complex worth 3300 rubles was spent on the 20 piglets of the experimental group. This entailed an increase in the total costs. The results of the study indicate a positive effect of the additive on the dynamics and growth rate of the piglets of the experimental group and on the cost of feed and nutrients, which favorably affects the profitability and economic efficiency of pork production.

The article reviews the effectiveness of the usage of enzyme-probiotic preparations “Rumit” and “Cellobacterin+” in feeding lactating cows. The test of enzyme-probiotic additives was carried out in the fall of 2019 in the conditions of JSC “Plemzavod Rodina” of the Vologda region. To study the impact of additives on the level of milk productivity, three groups of animals were formed by the method of balanced groups taking into account live weight, age, blood count, and productivity. The group of animals that received “Cellobacterin +” as an additive of 50 g per day for each head exceeded the control in terms of daily milk yield by 2.9% with a higher fat content of 0.01% and protein by 0.05% at lower food costs per product unit of 5%. High efficiency was also observed while using“Rumit” in feeding, the daily milk yield of cows’ basic fat contentin the experimental group exceeded the control by 7.4%, the yield of milk fat – by 4.7%, and protein – by 5.6%. Feed costs for products in this group were 7% lower in comparison with the control group. Due to the increase of per day milk productivity from one head, it is possible to get additional profit while feeding “Rumit” in the amount of 24.50 rubles, and while using “Celobacterin+” – 15.44 rubles.
