In the Krasnodar region there is a unique gene pool of animals both for dairy and meat. To assess the heifers the authors formed five experimental groups of animals, the most common species in the region. The authors studied the main economic, biological and exterior features: live weight, measurements, assessment of the exterior. The studies found that among intensive species with the largest body weight throughout the growing period, in 8-month old Charolais heifers superior Simmental ones at 17.4 kg. In one year old Simmental heifers were 9.2 kg (R˂0,05) ahead of Charolais and in 15 months – 10 kg (R˂0,05). Over the entire period of growth the highest rates of relative growth rates of heifers were obtained by red steppe breed type named Kuban, which had an advantage over the Aberdeen-Angus – 19.1%, Charolais – 5.6%, Hereford – 6.2%, and the difference between them and Simmental weren’t fixed. When growing, the animals become less tall, more stretched, wide and massive. We have noted that during the period of cultivation we had increased indices: stretch (9% – Red Steppe, 13.8% – Charolais, 16.1% – Hereford); chest (5.4% Aberdeen Angus). This reduces the index of long legs of red steppe – 5.6%, 10.9% for Charolais. The study of linear growth of animals confirms that the animal meat breeds of live weight increase was due to the extension of the body and increase the width of the pelvis and chest. Some different facts were observed in heifers of Red Steppe breed. For them, the most characteristic increase in the width of the chest was 1.44 times, as well as increasing the depth of the chest and chest girth behind the shoulders
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

Newest technical black berry variety named Piste (“Faith” in Greek) with colored flesh and juice breeded at Athens Institute of Viticulture (Greece) by researchers Zamanidi P., L. Troshin and P. Radchevskii in 2007 by crossing the Greek varieties Afoos (Mavrodafni x Alicante Boucher) with Ukrainian variety Odessa black (Alicante Bouchet x Cabernet Sauvignon). Duration of production period is 146-155 days. Growth of shoots is strong (2,1-3,0 m). The percentage of productive shoots is more than 90. The yield is very high: 25-30 t / ha. The average weight of clusters is 250 g. It can be characterized by high winter hardiness, drought resistance and increased resistance to fungal diseases in comparison with varieties of Vitis vinifera. Flower is hermaphrodite. Cluster is medium, conical, sometimes with wings, medium density. Berry is small, round, blue-black color with a thick waxy coating. The skin is medium thickness, dense and durable. Pulp and juice are intensely colored. Very high sugar content. Variety is intended for the production of intensely colored dry red wines of excellent class, as well as high-quality sparkling wines, dessert, sweet and liqueur wines; suitable for the manufacture of high-quality strong colored juices. When used in blends with other varieties enhances color, full flavor and enhances the bouquet of the wine
