PEAR AS A SOURCE OF BIOLOGICALLY ACTIVE SUBSTANCES FOR PRODUCTS OF FUNCTIONAL PURPOSES
06.00.00 Agricultural sciences
DescriptionBiochemical quantitative and qualitative indices of pear fruit have been investigated in six varieties of pears grown in Prikybanskoy horticultural zone of the Krasnodar region. The investigation has been done with pear fruit in the stage of maturity for harvesting and after 90 days after storage in refrigerator. Quantitative content of dry matter, sugars, vitamins C and P and fraction pectin content in fruits and squeezing of fruits as well as changes in the process of storage have been established

ECONOMIC-BIOLOGICAL FEATURES AND EXTERIOR MAINTENANCE OF YOUNG CATTLE IN THE KRASNODAR REGION
06.00.00 Agricultural sciences
DescriptionIn 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

PECULIARITIES OF NON-INFECTIONAL ARTHRITIS IN GROWING POULTRY IN AN INDUSTRIAL ENVIRONMENT
06.00.00 Agricultural sciences
DescriptionThe 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

INFLUENCE OF IMMUNIZATION ON THE DEVELOPMENT OF INTERNAL ORGANS OF YOUNG EGG HENS
06.00.00 Agricultural sciences
DescriptionAssessment 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
