The article is an analysis of the results of three years of work with sexing sperm in one of the two farms of the Kuban region which have implemented this tech-nology

The article provides the analysis of the most relevant causes for premature weeding of the experimental training farm “Kuban” (KSAU) cows’ basic herd and other farms of the Krasnodar region

The article provides an overview of materials of conferences on problems and prospects of the industry of cattle breeding

Growth of mini-zoos popularity urges production increase of the most demanded young growth species and this is complicated because of polietiological nature of wild carnivorous reproductive function insufficiency in captivity conditions

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

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 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 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

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

The article reflects information characterizing the significance of mastitis and endometritis in the indicator of premature disposal of cows from herds of large farms in the western regions of the Krasnodar region: an average of 30% of the total culling of cows. The effectiveness of veterinary measures in Pravoberezhny JSC of the Temryuk district for mastitis and endometritis in cows was assessed: 81-95%; fertilization index value ‒ 1.8; the duration of the service period exceeds the requirements by 20 days. The studies the nature of the influence of the drugs called Sepranol and Uteroton on the calving process and the occurrence of postpartum complications in cows from the herd, which was formed with violation of breeding principles. The use of the drugs Uteroton and Sepranol contributed to a 50% decrease in the calving index in calving cows by 50% compared with the results of the combined use of estrophan and oxytocin. The use of Uteroton reduced the damage from the lack of milk by 87880 rubles, and the use of Sepranol - by 171164 rubles. We have given practical recommendation on the use of Uteroton and Sepranol for veterinary effects on the body of cows in the early postpartum period in order to reduce the occurrence of complications
