Metabolism, productive performance of bright breeds of lacquer for feeding in the diet of aquaculture supplements

The paper examines the search and development of effective ways to reduce the proportion of grain in feed due to non-grain raw materials and partial or complete replacement of such high-value ingredients as animal proteins, fats, phosphatides, macro-and micronutrients and vitamin-mineral premixes through the use of natural resources of the local raw material base. The main nutrients contained in the protein-mineral supplement of the Dniester River indicate its unique, natural multicomponent composition, so it can be widely used, in particular, as a source of protein, amino acids, vitamins, macro-and micronutrients and possibly others. biologically active substances not yet identified by us. It was found that the brightness of the experimental groups in terms of live weight slightly exceeded the animals of the control group. Bright experimental groups made slightly better use of feed nutrients. Feed costs per 1 kg of live weight gain, they were 6.5-8.4% lower. When feeding the bright research groups aquaculture of the Dniester River, there is a tendency to increase the strength of their wool. The inclusion of aquaculture additives in the feed helped to increase the concentration in the blood of bright experimental groups of hemoglobin by 0.13-0.38 g (P> 0.05) compared with the control, which indicates an increased level of redox processes in the body. Moreover, the highest content of hemoglobin (12.01 vs. 11.63 g%) was observed in the blood of bright IV experimental group, in the diet of which was compound feed with the inclusion of 15 wt.% Additive. However, the difference in this indicator between the animals of the IV experimental and I (control) groups (0.38 g%) is statically unlikely (P> 0.05)

Adaptive changes in the ornithine cycle and amino acid synthesis in sheep liver with different meat productivity

The aim of the research was to study the ornithine cycle as the process of fixing ammonia and the formation of urea in the body of highly productive animals. In our experiments, we used a protein-deficient diet and urea as a nitrogen substitute for nitrogen-containing materials in the diet to reveal the mechanism of action of urea on animals, in particular on the biochemical processes of the ornithine cycle. There are some differences between Bukovinian sheep of the Askanian meat-wool breed and outbreds in terms of the ability to build muscle tissue. Our study reveals that the slaughter yield and the average daily gain consumption of Bukovinian-type meat of the Askanian meat-wool breed were higher in summer and in autumn, compare with purebred sheep. Sheep of the Bukovynian type of Askanian meat-wool breed have the intensity of enzymatic formation of urea in liver homogenates that is much higher in all experiments than in outbred sheep. A sharp drop in the activity of all stages of urea formation and glutamic acid synthesis in liver homogenates and significantly weakened urea formation was found in all experiments of the fourth series in comparison with the experiments in the third series. Increased muscle growth, high nitrogen deposition, and a much lower percentage of urinary excretion of ammonia and urea nitrogen, as well as higher activity of enzymes of the ornithine cycle and glutamic acid synthesis in the Bukovinian sheep type of Askanian meat-wool breed compared to outbreeds allow concluding that ammonia and urea in highly productive animals act less as finishing products of nitrogen metabolism than in low-productive animals

Modeling of Microbiological and Biochemical Processes under the Conditions of Steam Contact Sterilization in Containers of Turkey Meat Pate

The article proposes modes of sterilization of meat pate from turkey meat, which was determined by the method in which the actual lethality Ff relative to the microflora should be equal to or exceed the required lethality of the sterilization process Fn (Ff ≥ Fn) canned turkey pate. The results of the study of the dependence of the kinetics of biochemical reactions on the thermal, chemical and mechanical sensitivity of the processed product, on pressure, temperature  and chemical potential are presented. One of the effective ways to intensify the heat transfer process is the contact heating of the product by means of steam supply, which has a technological effect on the processed products. When comparing the results of the simulated results with experimental data, it is established that the solution of the problem of calculating the temperature field of the product on a computer gives quite satisfactory results between the calculated and experimental data. It is established that as a modification for the processed products it is necessary to solve thermohydromechanical equations with the corresponding initial and boundary conditions in addition to the transfer equation for each scalar quantity
