The article gives results of a comparative study of the growth and development of young cattle of Holstein breed belonging to the Reflection Sovering and Vis Baidial lines, born with the method of transplantation of embryos, and their coevals born with a standard method. Technology of growing of young cattle in both groups was identical, accepted in the economy. During suckling period, the heifers got 300 kg of full-milk. During a period from 3 to 8 months, they were contained in cages for small group maintenance, from an 8 month age, they were contained loose, on pasture grounds. Living mass and average daily increases of experimental heifers changed differently. The rates of height and average daily increases in an experimental group turned out to be higher, than for coevals of the control group. It is proved by the researches, that heifers born with the method of transplantation of embryos are equal to ones who were born with a traditional method in the rates of height and development and even excel coevals at the certain periods. In the age of the first insemination, living mass of heifers of the experimental group was 365 kg, which was 14 kg more compared to coevals of the control group. In all studied age-related periods, heifers of the experimental group excelled coevals of the control group in average daily increases. From their birth and up to 14-th month age, exceeding on increases was 37gr; to the age of the first insemination, heifers of the experimental group were more developed. Taking into account the genetic potential in heifer embryos and their best height and development, it proves the expediency of the use of transplantation of embryos
The authors of this article have developed a questionnaire for pet owners and conducted a research on the nutrition and health of domestic dogs and cats in the urban environment. By results of researches, it is concluded that in the conditions of the city, cats are a preferable type of pets. The preferred type of food is mixed one, with using dry, natural and wet food. Food standards are followed by 46% of owners of 100% participants of the survey and only 43.3% from consulters with veterinary specialists in the field of feeding of a pet. Among non-communicable diseases, urological diseases are more common: urolithiasis, cystitis, endometritis and ovarian cyst
This article is devoted to the study of various laboratory tests for the diagnosis of viral peritonitis of cats, conducted in 2014-2018. The study was subjected to 278 cats of both sexes, different breeds and mongrel, of different ages, which were taken to the veterinary clinic «Vita» and the veterinary clinic «Noah's Ark» in Krasnodar. Analysis of the results showed that in the diagnosis and differential diagnosis of viral peritonitis of cats, the most resultant is a combination of studies of Globulin in serum and a test for antibodies to coronavirus, or a solid enzyme immunoassay (tIFA) on IgG to coronavirus. In addition to clinical symptoms, routine laboratory studies, instrumental studies for the diagnosis of viral cat peritonitis, it is necessary to use additional research methods, although many of them have a number of shortcomings in sensitivity and specificity
