Influence of high temperatures on the behavior, productivity and bioenergetic characteristics of goats

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, daily behavior bioenergetic characteristics Saanen goats. A group breed 3rd lactation formed yield increasing. performed (average air up to + 22.3 °C) load an average 27.6 °C. Each lasted 12 days. It has been found that responded change by reducing productivity 10.70 % (0.35 kg). Hereby, mass fraction fat goat's this increased 0.09 %. During temperatures, spent little less time eating food, watering walking, but rested more supine position compared period. general, both periods, duration main acts corresponded physiological norms. decrease feed consumption caused number reactions chewing cuddy energy index, i.e. amount net feed, which transfers decreased 1.42 MJ Net per 1 0.62 MJ. Key words: goats, temperature, metabolic energy, behavior, bio-energy.
