Abstract. The research was carried out in IE «Babyni kozy» of Kyiv region at a goat farm where stable-pasture system goats is used. In winter, are kept free-stall housing on deep litter and during the grazing period, forage area. Goats milked milking parlor into milk line. article presents results researches influence ambient temperature thermo neutral period high temperatures productivity, dai...

The basic objective of the dairy goat farmers is to produce healthy and fertile animals at appropriate age, with maximum genetic expression long productive duration. Longevity an important economical parameter in breeding program goats. There are various factors which directly influence production longevity newborns such as age birth, season, herds flock breed. present study aimed effect parity...

Abstract The chemical composition of goat milk, especially fatty acid profile is recently renewed due to the role monosaturated and polyunsaturated acids in human nutrition. These nutrients are important analysed connection with different breeds receiving same breeding feed. aim this study was analyse milk relation breeds. Specimens for analyses were collected from individual animals like Latvi...

BACKGROUND A clear association of amino acid variation in the prion protein gene (PRNP) with susceptibility and resistance to classical scrapie exists in sheep, but not in goats. In this study we examined DNA sequence variation in the PRNP of 149 animals from two scrapie-infected herds of Saanen dairy goats, and identified 6 non-synonymous variants in the coding region. RESULTS In the larger ...

Ten multiparous crossbred goats, ®ve each of alpine beetal (AB) and saanen beetal (SB) were selected from the National Dairy Research Institute goat herd immediately after parturition. These were managed as per the practices followed in the institute's goatherd. Blood and milk samples were collected at biweekly intervals from day 14 post-kidding for 22 weeks (154 days). Somatic cell count, elec...

Caprine arthritis encephalitis (CAE) is a retroviral infection of goats. CAEV is closely related to the virus which causes MaediVisna in sheep and AIDS in humans. The first survey of the seroprevalence of CAEV in Hungarian goats was performed. Parallel with it we tried to ascertain whether there is any association between either the susceptibility of CAE or the appearance of clinical symptoms i...

The objective of this study was to estimate genomic breeding values for milk yield in crossbred dairy goats. The research was based on data provided by 2 commercial goat farms in the UK comprising 590,409 milk yield records on 14,453 dairy goats kidding between 1987 and 2013. The population was created by crossing 3 breeds: Alpine, Saanen, and Toggenburg. In each generation the best performing ...
