the role and efficacy of cotton seed:
reasonable addition of cotton seed in dairy cow diet can not only increase the food intake, milk yield and milk fat percentage, but also increase the natural estrus rate and conception rate of cows, reduce the interval between cows calving and indirectly increase breeding benefits.
although the cotton seed has a high fat content, it produces less heat in the body, which can effectively alleviate the heat stress of the cow in a hot and humid environment. in addition, compared with other measures to supplement fat, feeding cotton seed can overcome the postpartum nutritional deficiency problem of dairy cows.cotton seed provides energy, protein and effective fiber to the lactating cow diet. these three characteristics make cotton seed a unique feed ingredient. in addition, the special structure of cotton seed can also control the release rate of fat in the seed, which greatly enhances its value as a source of energy for dairy cows.
application of cotton seed:
under normal circumstances, each cow is fed 1 to 2 kg per day, and the maximum is 2.5 kg. if the cotton seed product in the dry matter of total daily feed is no more than 15%, since the cotton seed is too light, the uniformity of tmr mixing should be ensured, it is best to cast cotton seed after the long grass is finished to achieve balanced feeding of the cow.
