Factors of a flock itself The utilization of feed is different for chickens in different stages of growth. For example, chickens are low and chickens are high. Differences between individual chickens also have differences in feed utilization. 2 feed factors Different types of feed, the digestibility of nutrients is not the same. Soybeans contain anti-nutritional substances such as trypsin, saponin and hemagglutinin. These substances will affect their digestion and utilization and some physiological and biochemical processes of chickens. If heated properly, anti-nutrients can be destroyed. Rapeseed cakes contain glucosinolates, which are hydrolyzed by sinazymes to produce toxic substances such as thiocyanate or oxazolidinethione. These two compounds can affect energy metabolism and feed conversion rate, and some other feed ingredients (such as Solid, green feed, grass powder, feather meal, blood meal, etc. also contain some unfavorable factors that affect feed utilization. The scientific formulation of the three feed formulas, when formulated for feed, only the various nutrients (such as energy, protein, amino acids, vitamins, minerals, etc.) can meet the nutritional needs of chickens, and achieve the optimal ratio level before they can make use of feeds. The rate reaches the highest; otherwise, it will inevitably result in the waste of feed nutrients. Four feeds are processed and stored in the same feed. Because of different processing methods, their nutritional value is not the same. If the pressed cake has a lower protein content than the extracted quail protein, high temperatures may also denature the protein and reduce the nutritional value. The longer the feed is stored, the lower the nutritional value of the feed will be, and when it is severe, it will become mildewed and even cause animal diseases. 5. Feeding environment and feeding environment for stressed chickens, such as changes in temperature, humidity, ventilation, light, and harmful gas content in the air, can all cause chicken stress, thus reducing feed utilization.
