Abstract The objective of this study was to determine the impact of dihydroquercetin from Siberian larch and dry distilled rose petals (DDRP) on growth performance, carcasses characteristics and blood parameters of lambs from the Bulgarian Dairy Synthetic population sheep. For the purpose of the study there were used 30 clinically healthy male lambs aged 65 days, levelled by live weight. They were housed in a totally indoor barn and were divided into one control and two experimental groups, each consisting of 10 animals that were fed for 50 days. The control group (C) was fed ground alfalfa + granulated compound feed. The experimental groups (D) and (R) were fed on the same diet supplemented either with 7.5 mg dihydroquercetin/kg/day or with 545 mg DDRP/kg/day respectively. The carcass yield of lambs having consumed dihydroquercetin or DDRP compared to lambs from control group C do not have significant differences (p > 0.05). The carcass conformation of C or R groups lambs do not differ (70% - class P, 30% - class O). The 90% of lamb's carcasses from the experimental group D were classified in class P. The dihydroquercetin feeding increases the relative fat content (p ≤ 0.01) of lamb carcasses but adversely affects their conformation. No significant differences (p > 0.05) were found between 1st h and 24th h post-mortem pH of control group C and experimental group D. Compared to them the pH values of the experimental group R were by 0.14-0.15 pH units lower (p ≤ 0.05). No significant differences (p > 0.05) were found in the blood count of the three studied groups of lambs. Exceptions were made for haemoglobin (HGL) in the experimental group D which were with 6-7 g/l higher (p ≤ 0.05) than these in control group C and experimental group R and the blood glucose (GLU) in the experimental group R which is with 0.25-0.28 mmol/l lower than determined in control group C and experimental group D.

Abstract The objective of this study was to determine the impact of dihydroquercetin from Siberian larch and dry distilled rose petals (DDRP) on growth performance, carcasses quality and blood characteristics of lambs from the Bulgarian Dairy Synthetic population sheep. For the purpose of the study there were used 30 clinically healthy male lambs aged 65 days, levelled by live weight. They were housed in a totally indoor barn and were divided into one control and two experimental groups, each consisting of 10 animals that were fed for 50 days. The control group (C) was fed ground alfalfa + granulated compound feed. The experimental groups (D) and (R) were fed on the same diet supplemented either with 7.5 mg dihydroquercetin/kg/day or with 545 mg dry distilled rose petals (DDRP)/kg/day respectively. The experimental group D had 5.45% and 8.78% higher slaughter weight comparing to the control group C and experimental group R, respectively. The carcass yield of lambs supplemented with dihydroquercetin was 1.28% and 2.19% higher compared to control group C or the lambs that had consumed DDRP. The carcass yield of lambs having consumed dihydroquercetin is higher by 1.28% and 2.19% respectively compared to lambs from control group C or those having consumed DDRP. The carcass conformation of C or R groups lambs do not differ (70% - class P, 30% - class O). The 90% of lamb's carcasses from the experimental group D were classified in class P. No significant differences were found in the fatness degree. The dihydroquercetin feeding increases the relative fat content (P ≤ 0.01) of lamb carcasses but adversely affects their conformation. No significant differences (p > 0.05) were found between 1st h and 24th h post-mortem pH of control group C and experimental group D. Compared to them the pH values of the experimental group R were by 0.14 - 0.15 pH units lower (p ≤ 0.05). No significant differences (p > 0.05) were found in the blood count of the three studied groups of lambs. Exceptions were made for erythrocytes (RBC) and haemoglobin (HGL) in the experimental group D which were higher (p ≤ 0.05) than these in control group C and experimental group R. The conclusion made was that the use of the dihydroquercetin had a positive effect on the lamb's fattening, slaughter weight and carcass yield. Such an effect was not detected when DDRP was used.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.

The purposes of determining the influence of the light and sexing on growth performance and slaughter results atyoung quails from Balotesti population, was organized an experiment on 150 quails, betwen age of 28 and 70 days. The chicks were divided into two groups (control and experimental), and growth and slaughter performance were determined separately by sex. Have studied 2 lighting programs, a program of continous lighting with photoperiod duration of 16 hours (16 L + 8 N, control group) and a program with lighting with asymetric hours intervals with photoperiod duration of 16 hours (10L+2N+6L+6N, experimental group).Males and females from the experimental group were recorded average performance of growth high during the period 28 - 70 days. Live weight at age of 70 days was higher with 7.54 %, average weight gain was higher with 14.86 % and feed conversion rate was lower with 13.51 % at males from experimental group compared to males from the control group. Also, the live weight at the age of 70 days was higher with 18.09 %; average weight gain was higher with 35.12 %, while feed conversion rate was reduced with 30.08 % on females from the experimental group compared to females from the control group.The results of the slaughter at 70 days were superior in the caseof females from the both groups versus males. The average weight of the carcase was higher with 17.53 % in case of the females than that of males from the experimental group, and the carcase yield was 65.37 % at the females and 65.56 % for males. Also, the average weight of the carcase was higher with 5.08 % in case of females compared to that males from the control group, and the carcase yield was 64.20 % to females 66.70 % on males.Superior results recorded in the case of females and males from the experimental group recommended the program of lighting with asymmetric hours intervals in the growth of youth quail. Also, the higher slaughter results recorded in the case of females of the two groups recommended them in the meat production through a broiler of quail that combine advantages in the production of both males and females.

It is known that one of the most important reasons for the birth of weak calves is the impact of adverse factors on the physiological status of the cow, which in turn affects the intrauterine and postnatal development of the fetus and newborn. The results of studying the introduction of different doses of tissue biostimulator to cows during the dry period and its effect on the development of the conformation of calves received from them have been presented in the article. The experiment was carried out in 2019 on cows of Priobsky type of Black-and-White breed and calves obtained from them. In order to conduct the experiment four groups of dry cows-analogs have been formed with 10 heads in each for 55–60 days before the expected calving at the age of III lactation and older. When selecting animals the live weight and milk productivity of cows for the previous lactation have been taken into account. The highest growth rate has been observed in calves from cows the 2nd experimental group, which exceeded the control by 24,4 % (P ≤ 0,001). The best indicators of conformation development have been also observed in calves obtained from cows of the 2nd experimental group, which were injected subcutaneously with 22,5 ml of tissue preparation. So, oblique body length have been greater by 12,6 % (P ≤ 0,001), chest girth by 17,3 % (P ≤ 0,001), width of hook bones by 21,0 % (P ≤ 0,01), the width of the pin bones by 15,0 % (P ≤ 0,05). The lengthiness index was by 11,5 % higher (P ≤ 0,001), the blockiness index was by 4,1 % higher (P ≤ 0,05), and the boniness index was by 10,6 % lower (P ≤ 0,05) than in the control group herdmates.

The paper demonstrates the results on the effect of new specimen Vetom 20.76 on concentration of leukocytes in the blood of geese on the basis of the predatory fungus Artusbotus oligospora. In order to achieve the goal of the experiment, one control group and six experimental groups were arranged on the principle of paired analogues. Each group contained 10 geese aged 1 month. The geese from the experimental groups received Vetom 20.76 in different doses in the morning with water once a day: the geese of the 1st experimental group - dose of 0.5 ppm/kg of live weight during 15 days; 2nd experimental group - 1 ppm/kg of live weight during 15 days; 3rd experimental group - 2 ppm/kg of live weight during 15 days, 4th experimental group - 0.5 ppm/kg live weight during 30 days, 5th experimental group - 1 ppm/kg live weight during 30 days and 6th - 2 ppm/kg live weight during 30 days. The geese of control group didn’t receive the specimen. The concentration of leukocytes in the blood of experimental geese increases in the period of specimen application as well as in the period of its aftereffect. If Vetom 20.76 is prescribed for 15 days, the effect of leukopoiesis stimulation finishes on the 30th day. If the specimen is applied during 30 days, the leukocytes in the blood continue to increase up to the 60th day. This long-term application of Vetom 20.76 dosed 0.5ppm/kg increases leucocytes within the physiological norm. Application of higher doses (1 and 2 ppm/kg) the leukocyte concentration conforms to the physiological norm

The paper reveals the scientific and research experience when exploring the impact of Nabikat (nanobiological catalyst, a product of mechanochemical synthesis of silicon compounds of rice husks and green tea, produced by the Centre for Technology Implementation inNovosibirsk) on the carp organism. The experiment was conducted in May-November of 2017 at Troitsk Fish Factory. The researchers selected 500 specimens of Scaly Carp of which 2 similar groups were arranged. The first group served as a control group and received the feed from the fish factory, while the second group of carps received Nabikat dosed2 kgper 1 ton of feed. The researchers took blood of 10 fish from each group for morphological biochemical analysis. Hematological analysis included the following indicators exploring: hemoglobin content, number of red blood cells and total number of leukocytes. The researchers determined total protein, albumins, urea, glucose, total lipids, calcium, phosphorus and magnesium as biochemical parameters. All the indicators were within the standard before the experiment, except for albumins and calcium, which concentrations were low. When applying Nabikat, the authors observed changes of the main microelements in the blood: lower calcium concentration by 20.68% (P<0.001), magnesium – by 8.51% and higher phosphorus concentration in comparison with the control group. The carps of the experimental group had higher concentrations of albumins by 10.08%, erythrocytes by 4.76 and haemoglobin by 31.51% compared to the control group. Application of Nabikat results in improvement of physiological and biochemical blood parameters of the fish from the experimental group. This was revealed in facilitating of the blood respiratory function.

Abstract Improving pig growth performance, nutrient digestibility and pork quality is a continual goal of the pig breeding. For this reason, an increasing interest in using phytonutrients has been observed recently. The objective of this study was to determine the impact of Larix sibirica dihydroquercetin or dry distilled Rosa damascena petals on growth performance, carcass composition, meat quality, blood characteristics and histological changes in ovaries and liver in native Danube White fattening pigs. A total of 120 pigs were used in the experiment with duration of 45 days prior to harvest. The pigs were divided into five groups. The control group (C) was fed basal diet. The other four experimental groups were fed with the same diets containing either 3.5 or 7.5 mg dihydroquercetin/kg/d and 0.255 or 0.545 g dry distilled rose petals/kg/d. The supplementations with dihydroquercetin or dry distilled rose petals increased average body weight by 7.74-9.05%, average daily gain by 27.06-30.13%, and feed to gain ratio by 12.53-15.99% and decreased feed consumption by 5.24-13.84% and average liver weight by 10.53-21.12% compared to the control group. Two supplementations didn't cause pathological changes in histological structure of pigs' liver and ovaries, and didn't influence pH values and proximate composition of m. Longissimus thoracis and m. Semimebranosus. No pH determined stress-induced muscle damage was found and the pork carcasses were classified in classes E and U. The two used supplements reduced the blood LDL cholesterol by 13.27-14.29% as well as increased erythrocytes, platelets, haematocrit, mean red blood cell count, mean haemoglobin concentration in erythrocytes, triglycerides and total cholesterol.

This study was done to determine the impact of monieziosis infection combined with hypomicroelementosis on some hematological, biochemical and hormonal parameters of Soviet Merino sheep in the Astrakhan region. 20 sheep, aging 3 years old and average 43±1.6 kg body weight were used. Sheep were divided into two groups. First group contained 10 sheep and these sheep were naturally infected with monieziosis and clinically were suffered from hypomicroelementosis, emaciation, reduced growth rate, anemia, diarrhea and pale mucosa. Second group contained 10 sheep were apparently healthy and free from internal parasites and they were used as a control group. The first group was given Praziver (praziquantel and ivermectin) for treatment monieziosis, while they intramuscularly injected with Sedimin (selenium, iodine and iron) and were introduced daily into the feed with CoCl2. Faecal and blood samples from both groups were collected, before and 30 days after treatment, and analyzed for some hematological, biochemical and hormonal parameters. Our results revealed that there was a significant decrease in Hb and RBCs values, while total WBCs and eosinophils were significantly increased in the diseased group than in healthy one. Biochemical analysis showed a significant decrease in serum antioxidant enzymes (CAT, SOD and GSH-Px) and a significant increase in serum DC and MDA in the diseased group as compared with the control group. Hormonal analysis showed a significant increase in ACTH, TSH, Cortisol and a significant decrease in serum T4 and T3. After treatment with Praziver, Sedemin and CoCl2, there was a significant effectiveness to maintain blood parameters within normal levels in the experimental group and increase reproductive outcome from these sheep

The effect of the vitamin and mineral supplement "Kostoprav" on the level of erythrocytes and biochemical parameters of blood, as well as on indicators of live weight, absolute and relative growth and exterior indicators was studied. As a result of the research, it was established that the piglets of the experimental groups, which were fed the supplement "Kostoprav" at a dose of 20 g / kg against the background of the main diet, for 21 days. feed and 30 g/1 kg feed contributed to an increase in the live weight of weaned pigs by 15.6 and 18.4 % than in the control. The blood parameters of the weaning pigs were within the physiological norm and in the third experimental group were accompanied by an increase in the level of erythrocytes by 17.6 %, calcium by 18.7 %, phosphorus by 16.7 %, sugar by 13.2 %, compared with the control. group. This indicates an improvement in the digestive function of the gastrointestinal tract and an increase in metabolic processes in the body. The use of the vitamin and mineral supplement "Kostoprav" contributed to an increase in the measurements of the body length in the 3rd experimental group by 2.3 %, chest girth by 3.3 %, height at the withers by 0.9 % than in the control group.

Currently it has become popular to use different feed additives that allow us to increase the indicators of live weight gain by accelerating the metabolic processes in the body of animals, which allows us to take everything from the feed and to the maximum. With the advent of this trend in the market the range of feed additives in different directions has increased. For the research we have selected Vermiculite Expanded as a feed additive. The purpose of the research was to search the dynamics of changes in blood parameters in experimental steers in comparison with the control group against the background of the use of the feed additive Vermiculite Expanded. An assessment of blood parameters of Kazakh White-headed steers against the background of the use of mineral feed additive has been presented in the article. Three groups of steers have been formed for the research: the 1st group has been as a control and received the main economic ration; the 2nd and 3rd experimental groups received the feed additive to the main feeding ration in doses of 10 and 15 g/head for the groups, respectively. On the laboratory base blood tests we were able to search the correlation between morphological and biochemical parameters of blood and the growth rate of experimental steers. The steers of the 2nd and 3rd groups during the experiment had an advantage in blood serum indicators in terms of both total lipids and glucose, in the end, the difference in percentage ratio with the control group was 14,08 % in the 2nd group and 12,60 % in the 3rd experimental group. It is worth noting that the concentration of phosphorus and calcium in the blood was at the high level, which in our opinion reflects the influence of the feed additive Vermiculite Expanded.
