ABSTRACT
The purpose of the reconnaissance experiment was a series of preliminary studies aimed at breeding aspects of increasing the down output of goats of local breeds and reducing the cost of manual labor in the technology for obtaining down. The research was carried out at the “Aiganym” farm of the Zhambyl district on one-year-old goats of the Kazakh coarse-haired and Gorno-Altai downy breeds as well as their crossbreeds. Animal groups were formed according to the principle of analogue groups, taking into account age and live weight. Animals downy breed were more than 2.5 times higher than the animals of the local Kazakh coarse-haired breed in terms of down output. Crossbred animals obtained by crossing animals of the Gorno-Altai downy and Kazakh coarse-haired breeds occupied an intermediate position between the original breeds in terms of most down indicators. For 5 days, the goats of the experimental groups underwent intramuscular injection of the cyclophosphamide drug at a dose of 7 ml/kg of body weight. The results showed one-year-old goats of the Kazakh coarse-haired and Gorno-Altai downy breeds subjected to an intramuscular injection did not show a molt of down, but the output during their brushing was, respectively, 14.3 and 7.8% higher than that of the peers in control groups due to better separation of down. The down output in experimental animals partially increased and its technological qualities improved – the thickness of the down fiber was 0.3 and 0.5 microns thinner in experimental animals, and, as a result, had a higher comfort factor.
