In the prevention and treatment of cow ketosis, the regulation of glucose and fatty acids is the main focus, while ammonia intoxication is largely ignored. The intensity of formation of the rumen ammonia can be reduced by ionophore antibiotic monensin. Hop cones contain a number of biologically active components including phytoionoрhores: prenylated polyphenols lupulon, humulon and their derivatives. Therefore, hop cones can be considered as a potential substitute for antibiotics-ionophores. Vitamin E, fed to ruminants in large quantities, stimulates the cellulosolytic bacteria of the rumen. Accordingly, co-feeding cows with hops and vitamin E supplements can reduce ammonia formation without inhibition the carbohydrate fermentation in the rumen. The experiment used two groups of dry Ukrainian dairy black-and-white breed cows with productivity 6–7 thousand kg of milk for previous lactation, 10 animals per each group. The trial was performed during the last 3 weeks of dry period and the first 3 weeks after calving. Animals were fed a standard balanced diet containing: grass silage, corn silage, barley grain, corn grain, soybean meal, molasses, salt, mineral and vitamin premix. The first group was the control. The diet of second group was supplemented with 300 mg of α-tocopherol acetate (0.6 g of Rovimix E-50) and 1g of dry hop cones per kg of DM. Prior to calving, the tested feed additive reduced the concentration of lipid peroxidation products (P < 0.05) in the blood plasma without affection other parameters. More significant changes were detected after calving. An increase in glucose concentration (P < 0.05), triacylglycerol (P < 0.05), cholesterol esters (P < 0.05) and a decrease in the concentration of NEFA (P < 0.05) were found in the blood of cows of the experimental group in a week after parturition. One month after calving, differences between control and experimental blood plasma parameters were significantly less pronounced. Therefore, addition of 300 mg of α-tocopherol acetate and 1 g/kg of dry hop cones per kg of dry matter of the diet during the transition period stimulates liver glucose synthesis and reduces the rate of fatty acid release from adipose tissue. The specified feed additive can be used to prevent metabolic disorders in early-lactation dairy cows.

The possibilities of increasing the productivity of different poultry species by increasing the absorption of feed nutrients can be realized through the use of new biologically active components that are usually added to traditional feed based on live cultures of microorganisms of the normal microflora of the gastrointestinal tract. The effectiveness of different probiotic drugs varies depending on the types and strains of microorganisms that are included in their composition, the dose of the drug, the scheme of its use, age, type, physiological state and productivity of animals. The research has been carried out to study the influence of the use of the probiotic feed additive Amilocin in the diets of laying hens of the cross Hisex Brown on their productivity. The positive influence of the studied feed additive on the live weight and livability of laying hens, egg productivity, quality and quantity of eggs obtained, morphological and biochemical parameters of the blood of experimental poultry, slaughter parameters and chemical composition of the meat of experimental laying hens has been established. The optimal rate of introduction of probiotic feed additive Amilocin into the diet of laying hens has been determined (0,5 g/head/day at the beginning of egg laying during 10 days, 1,0 g/head/day at the peak of egg laying during 10 days, followed by 1 g/head/day monthly for 10 days until the end of egg laying). The economics effectiveness of using the probiotic feed additive Amilocin per 1,0 ruble of costs was 1,24– 1,35 ruble. According to the research data recommendations for the use of the probiotic feed additive Amilocin have been proposed.

AbstractIntroduction: The transition period is the most challenging time for dairy cattle, which is characterised not only by negative energy balance but also by fatty tissue mobilisation.Material and Methods: The efficiency of energy pathways, β-oxidation in WBC and glycolysis in RBC (based on deoxyglucose transmembrane transport) were estimated. Insulin in blood plasma was determined using ELISA.Results: After calving and up to one month after delivery, a significant drop in blood plasma level was noticed, simultaneously with a rise in β-oxidation from 18.93 ±3.64 to 30.32 ±5.28 pmol/min/mg protein in WBC. A strong negative correlation between these two indices (r = −0.68) was found. During the period of transition to lactation an increase in glucose cross-membrane transportation from 41.44 ±4.92 to 50.49 ±6.41 μmol/h/g Hb was observed. A strong positive correlation between glucose transportation in RBC and β-oxidation in WBC (r = 0.71) was noticed. These data are in agreement with results of studies on dairy cows using liver slices from dairy cows in late pregnancy and different stages of lactation, in which changes in gene expression were analysed.Conclusion: It seems that measuring fatty acids oxidation and glycolysis using isolated blood cells may be an adequate and relatively simple method for energy state analysis to estimate the state of dairy cow metabolism and animal health.

Abstract The transition period is the most stressful for dairy cows in terms of metabolic rate and characterized by dynamic changes in the hormonal profile, loss of appetite, negative energy balance, nutrient and vitamin deficiencies, compromised immunity and oxidative stress. The aim of the research was to balance the increase in cows’ productivity and the consumption of nutrients from the feed during the transition period through the use of energy feed additives (EFS), high protein feed concentrate (PFC) in combination with biologically active (BA) substances. Thirty-six dairy cows of black-motley breed were divided into 3 groups: (1) The main diet (G0, n = 12), not supplemented with additives, (2) additive 1 (G1; supplemented with 0.5 kg EFS / cow per day, n = 12), (3) additive 2 (G2; supplemented with 0.5 kg EFS; 0.5 kg PFC and 0.06 kg BA / cow per day, n = 12). The experimental part of the feeding lasted for 20 days before calving and the first 100 days after calving (DPP). Blood samples were collected during the first and the third months after calving. The biochemical analyzer was used to measure blood serum components. The milk yield was recorded monthly throughout lactation. BCS losses from 7 days prior to calving to 28 DPP were -0.29 for Gr2, -0.42 for Gr1 and -0.60 for Gr0. Feeding with additive 2 (Gr2) increased milk yield (p≤0.05) in the first 100 DPPs and (p≤0.001) 305 DPPs compared to G0. The number of samples with SCC ≥ 500 000 / ml. per 100 DPP was 51% in the Gr0 group, 27% in Gr1, 25% in Gr2. Also, microbiological control showed an excess of Bacterial cells in the milk of cows from group G0, which correlates with SCC indicators. Cows from Gr2had a lower content of ketone bodies (P≥0.001) and higher (P≥0.001) antioxidant activity of blood serum compared to Gr0. Cows from Gr2 had an increase in ALT activity by1.4 times (P &lt;0.05) from the first to the third months after calving.

During fish farming, significant attention should be paid not only to the quantity, but also to the quality of marketable carp, primarily its physiological condition and high adaptive plasticity. Recently, increasing importance is attached to fish farming by industrial methods using various types of feed. A characteristic feature is the almost complete absence of natural food organisms. Significant success has been achieved in the creation of various starter compound feeds that can replace live feed when the larvae switch to exogenous nutrition [1]. During the development of artificial rations, attention was paid to the balance of basic structural elements of nutrition and, to a lesser extent, to various biologically active substances. For the majority of farmed fish, the need for protein and essential amino acids, fat and certain fatty acids, carbon and minerals has been established, on the basis of which, starter and production feeds, as well as various vitamin and mineral premixes, were developed [2]. However, natural food contains a wider range of biologically active components that are the regulators of many metabolic processes of body. Therefore, live food in fish nutrition, even in small proportion, can supplement the energy components of artificial feed and thereby significantly increase the balance of the diet [3].

The purpose of this research was the study of selenium (Se) and vitamin E (vit. E) concentrations in dairy cows blood within the region of Thessaloniki. The survey included 65 dairy cow farms in the region of Thessaloniki from which samples of blood were collected from 10 female adult animals from every farm. Out of the total 650 cows examined in the 65 farms, 40% presented deficient concentration of Se in blood (<0,08 μg/ml), 29% marginally deficient concentration (0,08-0,12 μg/ml) and only 31% normal concentration (>0,12 μg/ml). Regarding vit. E, only 4%, out of the 650 cows examined, had deficient concentration in the blood plasma (<2 μg/ml). It was concluded from the above that, in the region of Thessaloniki, a significant percentage of the dairy cows run the risk of Se deficiency diseases. On the contrary, the case of vit. E deficiency, should be regarded as improbable for these animals.

The use of different feed processing methods using exogenous feed additives to improve the digestibility of plant feed ingredients in pig feeding has been studied for decades. In the research laboratory of the Institute of Forage and Agriculture of Podillya NAAS, compositions of enzymes with cellulase and amylase activity were studied. They are able to effectively break down non-starch polysaccharides in cereals, increase digestibility and absorption of feed nutrients. The purpose of this work was to study the zootechnical efficiency of the use of biologically active in the composition of feed pigs for fattening. In the presented material, the influence of feeding cellulose amylolytic enzyme additive on the productive qualities of pigs for fattening is highlighted. The cellulose amylolytic additive contained α-amylase with an activity of 9342 IU/h and cellulase with an activity of 540 IU/h. Studies in pigs were performed in two stages: the equalization period (15 days) and the main (71 days). For feeding pigs, a feed mixture was used, consisting of feed grown directly on the farm – barley, wheat, soybeans. The diet of the control group consisted of 63 % barley grain, 27.5 % wheat grain, 9 % soybean meal 0.5 % mineral supplement. Pigs of the experimental group were fed cellulose amylolytic feed additive at the rate of 5 g of cellulase and 1 g of amylase per 1 kg of feed. Feeding supplements determines the intensity of the process of digestion of proteins, fats and carbohydrates. Cellulose-amylolytic additive affects the absorption of carbohydrates in the diet, providing an increase in the digestibility of the control and experimental groups, respectively, neutral-detergent fiber (38.2 and 46.7 %), acid-detergent fiber (18.7 and 36.5 %), the amount easily hydrolyzed carbohydrates (85.4 and 90.2 %), hemicellulose (65.7 and 61.5 %), cellulose (13.2 and 21.4 %). The decision on the feasibility of including cellulose-amylolytic additive in the diet can be confirmed on the basis of its use during the scientific and economic experiment. In the control group, the average daily increase in live weight was 725.07 g, and in the experimental group by 19.7 % more at the level of 902.53 g. It was also noted a positive effect on the formation of body biomass, development of individual organs and their systems.
