Application of cottonseed meal in poultry feed

YuanChao et al. (2014) studied the effects of cottonseed meal on laying hens’ egg production performance, egg quality, and residual free gossypol in eggs by adding cottonseed meal to chicken feed. The results showed that the egg production rate and egg production rate of the group adding 8% expanded cottonseed cypress were The average egg weight was significantly higher than that of the 6% cottonseed meal group (P<0.05), and the yolk color of the latter was significantly lighter (P<0.05). In addition, the addition of 6% cottonseed meal significantly increased the free cotton in the yolk and egg white. phenol concentration. Batonon–Alavo et al. (2015) used cottonseed meal to replace soybean meal in broiler feed. When the replacement amount reached 40%, the feed intake of broiler chickens increased and their growth performance decreased. However, this substitution had no effect on the growth performance of young chickens in the early growth period. No negative effects. Qiu Liangwei et al. (2012) fermented cottonseed meal through two processes. The crude protein content of fermented cottonseed meal increased to 59.64% and 60.88% respectively, and the small peptide content increased to 19.41% and 23.59% respectively, and Leghorn Egg Rooster was strong. Feed metabolism test results showed that the energy utilization rate and nutrient digestibility of fermented and enzymatically hydrolyzed cottonseed meal were higher than those of unfermented cottonseed meal. Feng Jiangxin et al. (2015) showed that the apparent metabolic rate, average daily weight gain, and feed conversion rate of yellow-feather broilers in the cottonseed meal group were significantly increased in terms of crude protein, calcium, and phosphorus.

Cottonseed meal in stock

From May to July, due to reasons such as rising temperatures, the moisture of the cottonseed meal in stock is lost rapidly, and the aflatoxin B1 content is also increased rapidly. It is not recommended to store cottonseed meal outdoors from May to July and should be stored indoors instead.

The moisture content of cottonseed meal in stock increases or decreases by 1.0%, and the protein content decreases or increases by 0.5% accordingly. From this, the moisture and protein content can be appropriately adjusted in actual production according to the sales plan and theoretical moisture loss, so that the product quality when shipped meets customer needs.
