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.

Modern research shows that several plant extracts containing tannins can improve the nutrition and the health status of farm livestock. In view of the fact that there is a certain dependence of the tannin activity on the source, geographical distribution, the assessment of their effects on changing the intestine microbiota is poorly studied. Experimental studies were conducted on 120 heads of 7-day-old broiler chickens (4 groups, n = 30, 4 replications). The control group received the main ration (MR); the first experimental group – MR + extract 1 (1 ml/kg of live weight); the second experimental group – MR + extract 2 (2 ml/kg of live weight); the third experimental group – MR + extract 3 (3 ml/kg of live weight). An extract from Quercus cortex was additionally included in the composition of experimental groups’ rations. Sequencing the content of samples from the small and cecal intestine was carried out at the second generation sequenator MiSeq Illumina (the United States). As the concentration of the extract increased, micro-organisms of phylum Bacteroidetes shrunk (I) and then disappear (II, III). The maximum concentration found a decrease of phylum Firmicutes (p ≤ 0.05) and an increase of Proteobacteria (p ≤ 0.05). This group also revealed a decline of representatives of class Bacilli (p ≤ 0.05). In groups I and II, representatives of class Clostridia decreased by 14.6-50.5% in comparison with the control. The ratio of representatives of microorganisms in the intestine depends on the number of tannin-containing substances in the extract, which reveals the need for a more detailed examination of this factor as a source of such substances.

A study of the safety of the use of feed additive Liaform for the target species – broiler chickens. Liaform is a yellowish liquid with a specific odor. The feed additive contains lactic acid, formic acid, sodium formate, propionic acid and water. Given the composition of the additive, it can be attributed to two functional groups: preservatives – substances or microorganisms that protect feed from damage by microorganisms or their metabolites, acidity regulators – substances that regulate the pH of feed. For the study was formed on the principle of analogues of 3 groups of broiler chickens of 15 heads (control and 2 experimental) from 8 days of age. Feeding of chickens of the control group was carried out by standard complete feed. Feeding of chickens of the first experimental group was carried out with standard complete feed, in which the feed additive Liaform was added at the rate of 2 g / kg, feeding of chickens of the second experimental group was carried out with standard complete feed, in which feed additive Liaform was applied in 10 times the recommended dose of 20 g/kg. During the experiment, the general condition of the bird, the safety of the bird, zootechnical and hematological parameters were monitored. It was found that the studied feed additive in 10 times the recommended dose does not have a negative impact on productivity, growth and development of broiler chickens, feed absorption. As a result of the use of Liaform feed additive in 10 times the recommended dose, the live weight of broiler chickens in the experimental group was higher compared to the control and lower compared to the recommended dose. The use of a feed additive in 10 times the dose did not have a negative effect on hematological parameters and serum protein levels, did not cause a negative effect on the condition of internal organs.

The expediency of using the probiotic drug Biolax-U in the rations of lactating and dry cows of Black-and-White breed has been studied and scientifically proved. The influence of this drug on the morphological and biochemical parameters of animal blood has been determined. The composition of the probiotic drug Biolax-U consists of eight strains of a balanced complex of living lactic acid bacteria, yeast and actinomycetes, as well as biologically active substances. For experimental studies conducted on 2 groups of cows have been selected by the method of pairs-analogs, the influence of feeding of feed have been prepared with the use of the microbiological drug with probiotic action Biolax-U on feed consumption, morphological and biochemical changes in blood has been studied. Analysis of the rations of cows indicates that the content of calcium, phosphorus, magnesium, sulfur and trace elements such as manganese, copper, zinc and cobalt in the feed has been reduced. It has been found by studies that the use of probiotic drug Biolax-U had the positive influence on the feed intake, digestibility and better assimilation of feed nutrients and contributed to the improvement of blood morphological and biochemical parameters. For example, in animals of the experimental group hemoglobin has increased by 3,6 % (Р < 0,05), red blood cells by 10,1 (P ≤ 0,05), the content of leukocytes by 4,43, carotene by 9,6, glucose by 3,4; reserve alkalinity by 15,6, calcium by 19,4 (P ≤ 0,01), and phosphorus by 18,4 % compared with the control group of animals. During the lactation significantly improved hematological parameters including alkalinity reserve by 5,11 %, calcium level by 11,1, phosphorus by 8,6, hemoglobin by 14,2 %, the content of erythrocytes by 12,3, leukocyte by 3,86, and carotene 11,1 % against the parameters of animals of control group. The improvement of morphological and biochemical parameters of blood of cows indicates about stimulating effect on hematopoiesis and the general clinical condition of animals that contributes to the improvement of metabolic processes when using feed prepared with the use of microbiological drug with probiotic action Biolax-U.

The article is devoted to the solution of an urgent problem- influence of different lighting modes on the dairy productivity of cows. 2 groups of cows with 20 heads each were formed. In control group, light in the cowshed was 50-75 Lux for a light period of 7.5 h in January to 16.5 h in June, and in experimental group - 150-200 Lux and 16 h, respectively. It was found that the intensity and duration of illumination affects physiological state, reproductive ability and milk productivity of cows. In the experimental group of cows, compared with the control group, hemoglobin content in blood increased by 4.6% (P < 0.01), red blood cells - by 20.6% (P < 0.05), total protein - by 11.2% (P < 0.001), glucose - by 39.1% (P < 0.05). There was a tendency to increase the total calcium and inorganic phosphorus in blood serum of cows of the experimental group. The level of alkaline phosphatase in blood serum of cows in the control group was 71.5% (P < 0.01) higher than that of cows in the experimental group. Milk yield per 1 cow in the experimental cowshed was 433 kg more than in the control. The cost of 1 kg of milk in the experimental group was 0.94 rubles lower, and the profitability of milk production and sales is 9.42% higher than in the control group. To increase the milk productivity of cows, it is recommended to increase light level in barns for tethered keeping to 150-200 Lux, with the duration of lighting in the winter and transition periods of year up to 16 hours per day.

The reproductive traits of sows are of paramount importance in the production of high-quality pork. The world experience of pig farming shows the need to solve first of all the feed problem. Diets unbalanced in the content of vitamins restrain the manifestation of genetically inherent high prolificacy of sows. The purpose of the research was to study the influence of feeding the vitamin feed additive “LipoCar” on the reproductive traits of sows and the biochemical parameters of blood serum. The results of research on the introduction of vitamin feed additive “LipoCar” into the diet of pregnant sows have been presented in the article. The experiment has been carried out in the production conditions in JSC “Linevsky pedigree farm” on sows of Large White breed. Pregnant sows have received a basic diet, balanced for all the normalized elements of nutrition. Sows of the experimental group in the composition of the basic diet fed the feed additive “LipoCar”. The dosage of the drug “Lipocar” was 2,1 g/head/day. “Lipocar” has been fed for 20 days. The total duration of the experiment was 3 months. When introducing the vitamin feed additive “LipoCar” into the main diet of sows in the second half of pregnancy the increase in the number of piglets in the litter by 1,6-6,8 % and the weight of the litter – by 5,6-56,2 % (P ≤ 0,001) have been revealed in comparison with the control group of animals. There was a higher content of carotene in the blood serum of sows of the experimental group by 50,0 % (P ≤ 0,01), vitamin A - by 48,7 % (P ≤ 0,05), and total protein – by 4,9 % (P ≤ 0,05).

Purpose: to study the effect of ethanol on the parameters of THC, the percentage of granulocytes and total protein in the hemolymph of the Red claw crayfish (Cherax quadricarinatus).Materials and methods. The object of this experiment was 26 males of the Australian red-clawed crayfish (Cherax quadricarinatus) weighing from 23 to 83 g. The individuals were evenly divided into two experimental groups - with an injection of ethanol and a control group without an injection of 13 crayfish for each group. The injection dose was 2515 mg per 100 g of body weight. A day after the introduction of ethanol, hemolymph was taken with a syringe from the ventral sinus, the syringe was pre-washed with a 4% EDTA-Na2 solution. Three parameters were determined: the total hemocyte count (THC), percent granulocytes and percent total protein content. Counting of hemocytes and determination of granulocytes were performed in a Goryaev chamber under a light microscope. The total protein was determined by the refractometric method.Results. Differences in THC and total protein between the groups were statistically unreliable (p>0,05). THC in the experimental group is 36% more than in the control group. The total protein after the introduction of ethanol actually increased by 0,7%, and relatively by 14%. There were statistically different indicators of the proportion of granulocytes (p<0,05) - the average value of 33,1% in the experimental group versus 24,5% in the control group. A reliable (p<0,05) strong feedback was revealed between the total protein and the mass of individuals in both experimental groups, while in the experimental group there is a visible shift in the values of dependent hemolymph indicators towards an increase in smaller individuals.Conclusion. A single injection of ethyl alcohol with a dosage of 2515 mg per 100 g of body weight into the hemolymph of C. quadricarinatus does not cause significant changes in the THC and total protein after 24 hours. At the same time, the proportion of granulocytes actually increases by 9%, relative to 37%. This may indicate that granulocytes are involved in the formation of cancer defense mechanisms when exposed to toxic substances. The effect of different dosages of ethanol injections and the duration of its effect on hematological parameters requires additional consideration. It is necessary to investigate its effect on other indicators, such as the pH and buffer capacity of the hemolymph, the concentration of hemocyanin, glucose, lactates and calcium.

The aim of the study is to increase the productive qualities of broiler chickens by including ultrafine silicon oxide into main diet. During the experiment, the biological effect of ultrafine silicon oxide on broiler chickens was estab-lished. Use of ultrafine SiO2 particles for poultry feeding contributed to an increase in the number of red blood cells and content of total protein and albumins. By the end of the experiment, the number of red blood cells in birds in-creased by 17.43% (P≤0.001) – in the blood of birds of the first experimental group, 16.51% (P≤0.01) – the second one, 20.80% (P≤0.001) – the third experimental and 21.71% (P≤0.001) – the fourth experimental group, compared with the indicator of the control group. The amount of total protein in blood serum of chickens of the first and the second experimental groups increased by 1.36-1.39 %, in the third and fourth ones there was a significant (P≤0.05) increase by 5.45 and 3.05%, respectively. The blood glucose content of chickens in the experimental groups is higher by 8.04-23.65% compared to this indicator with ones in the control group. During the experiment feed con-sumption per 1 kg gain of live weight decreased: in the first experimental group by 3.00 % in the second by – 0.50 %, the third – 6.00 % the fourth– by 4.50 %, compared to this with the control group. The chicken’s vibrancy of the first the experimental group was higher by 4.77 %, the second – by 6.20 %, the third – by 19.25 % and the fourth– by 11.59% than in the control one. Consequently, when converting the feed energy into the body energy of a broiler chicken, the energy conversion coefficient of the experimental group of poultry is higher than that of the control one by 7.16-21.76 %. Thus, the most optimal dose for further research was determined.
