Black goats have the highest feed utilization rate, the largest production volume and the lowest feeding cost in a suitable warm environment. The temperature is lower than the critical temperature, the metabolic rate of the sheep is increased, the feed intake is increased, and the feed is increased

Black goats have the highest feed utilization rate, the largest production volume and the lowest feeding cost in a suitable warm environment. The temperature is lower than the critical temperature, the metabolic rate of the sheep increases, the feed intake increases, and the feed utilization rate decreases. Low temperature often accelerates gastrointestinal peristalsis, shortens the time of feed residence, and affects the digestion and absorption of sheep; On the contrary, the temperature is too high, the energy loss of the sheep is reduced, and the energy maintenance is low, although the feed intake decreases and the feed utilization rate has an upward trend. Sometimes the temperature rise and fall does not change the digestibility or metabolic energy of the feed, but the increase in temperature can reduce the net energy. #黑山羊 #
