The results of the analysis of the level of implementation of the method of cattle breeding by embryo transfer in an agricultural company from the Krasnodar region with a developed sector of cattle breeding. We have assessed the level of development of all stages of the method in the household, identified errors in the selection of animals and the increased value of culling donor cows and recipients, reduced duration of using recipient cows and high cost of all phases of the transplant process. We have raised a question of the need to change the criteria of economic evaluation of the results of the method

The article contains information that allows us to assess the importance of intermuscular abscesses in the range of indicators that affect the quality of pork produced in modern pig breeding complexes with flow technology. Calendar periods with increased rates of carcass rejection at a meat processing plant due to intermuscular abscesses were identified; the numerical value of rejection was established: from 2-3 carcasses from a batch in the "safe" months to 20-30 in the "unfavorable" ones. The article presents opinions of researchers on the causes of intermuscular abscesses are given; the importance of violations of vaccination technology is highlighted; an officially approved immune-prophylaxis scheme used at a large meat processing enterprise in the Krasnodar region. The analysis of the specialist's actions during the implementation of vaccine injections in growing animals was performed, and possible causes of process violations that can lead to the occurrence of an abscess were determined. The work justifies use of in vivo and post-slaughter ultrasound diagnostics of an abscess as a pathological object with certain characteristics. We have also noted the necessity of economic justification for the purchase of a mobile or stationary ultrasound device by a company

The article contains complex research results dedicated of reproduction the cattle of the animal breeding industry in the agricultural holding called “Kuban”. Key indicators characterizing reproductive function at cows were set; they were estimated in terms of the plans of the economy in the milk cattle breeding industry. The reduced values of the birth-rate of calves were revealed on 100 cows and in the term of the production use of cows, their main reasons were set. The performed calculations prove the possibility of increasing the profitability of milk production

The article contains generalized information on the activities of peasant farms in cultivation of turkey for meat using outdoor technologies. The production is cost-effective, although the rates of live weight gain and the cost of feeding do not reach the requirements for the cross. There are some reserves to improve the profitability (introduction of floor cell technology, optimization of feeding and participation in government support programs)

The article contains the summarized information on the activity of a farm having a sector of “Agrotourism”. There was revealed the positive dynamics of development of agricultural tourism in the Krasnodar region, the extension of offered services in this direction; there was set the obstacles restraining the development of the present sector. There were named the reserves to increase the profitability: (domestic milk production and participation in programs of state support

The article contains data on results of calving and blood tests of heifers moved from the Astrakhan region in the Temryuk district of the Krasnodar region in the condition of early pregnancy. According to the accompanying documents, cell blood count, hemoglobin and biochemical parameters were consistent with species and age normal. Calving took place without complications and did not require delivery; received 36 of 36 calves from cows. The quality of the calves found to be satisfactory. On the 45th day of service period, clinical signs of impaired health status were present in 2 animals, however biochemical markers of liver disease, inflammation, and anemia was identified in 7 heifers. In the context of work on creation of livestock combined milk and meat productivity of inseminated heifers and heifers of the Simmental breed the Simmental semen (25 cows) and Aberdeen Angus (34 cows) breeds. Fruitfully inseminated 55 out of 60 animals; indicator of severity of calving was 8 % for Simmental cows. Calves of Simmental breed and Simmental-Aberdeen Angus cross-breeds meet the requirements for live weight at birth and the exterior. Farming on the formation of herds of milk and meat direction of productivity are found to be effective

The problem of industrial poultry farming is the emergence of a growing birds’ arthritis. Inflamed joints are usually seen in poultry and accompanied by the inability to take food and water. The most characteristic of this problem in broiler chickens, young chickens of egg cross, i.e. birds of a short period of use. This is the reason for their rejection of the herd. Culling chickens are 10%, which furthermore reduces the total amount of livestock and leads to a reduction in the cost-effectiveness of growing birds. The analysis of our data gives a reason to believe that the main reason for culling poultry is acute inflammation of the joints or arthri-tis. According to the authors to ensure optimal rearing program, which should include the prevention of premature retirement of birds not only due to infectious diseases, but also the prevention of metabolic disorders and the exclusion of factors that could cause disruption of immunological reactivity. Currently, this program needs to be improved, which is particularly important in relation to vaccine pre-vention

The article contains a synthesis of modern views on the problem of ketosis and related metabolic disorders. We have given evidences of the exceptional role of hypoglycemia in the development of progressive metabolic diseases of cows during the transition period. The necessity of implementing a program for critical period with mandatory control of glycemia was substantiated

Assessment of the nature of the impact of preventive immunization of growing chickens on the results of cultivation and state agencies involved in immune reactivity is the first step in finding ways to eliminate the negative effects of immunization. The results show that the healthy birds posses two sharp peaks of exceeding norms by weight of the liver – aged 50 days and 84 days - more than 20%. Spleen weight at the age of 40 days exceeds 20%, and 50 days shows the greatest deviation from the norm. In the future, the relative weight of the spleen de-creased, and 84 days of age comes into compliance with the norm. The most significant change in the relative weight of the spleen and liver of poultry is set at the age of 50 days. The authors attribute this fact with a forced need to implement an immune response in a specified bodies accumulating overload antigenic incentives

The article contains research results on the influence of duration of the first lactation period of sows on reproductive qualities. The authors have detected basic problems which reduce indices reproduction of purebred pigs of the breed of Yorkshire and hybrids of F1 (Yorkshire x Landras) under conditions of a new complex. It was found that because of the increase in duration of lactation period of the sows it is impossible to increase the safety of the piglets with a reduced live mass (from big nests and slow in growth) and improve the reproductive quality of sows. This method has been used in the economy what led to a notable improvement in the indices of pig breeding
