1. Suppressing dust Due to the improvement of processing technology, the residual oil rate in the cake raw materials is reduced. When the concentrated feed is not refueled, the appearance is dry and easy to dust, resulting in energy loss. After refueling 1%-1.5%, the concentrated feed has a moist appearance and inhibits the flying of dust.
2. Reduce the cost When the ambient temperature exceeds 30 °C, the internal circulation of the chicken is obviously accelerated, and the demand for nutrients is increased. The main increase is the energy demand. However, the problem of insufficient energy intake is more prominent, and in this case, only the increase in the concentration of nutrients in the feed, especially the increase in energy content, can solve the problem of egg production decline. When the temperature is too low, if the ambient temperature is lower than 2 °C, the chickens maintain a normal body temperature and the energy demand is significantly increased. At this time, chickens can increase their feed intake by increasing their feed intake, while increasing the loss of protein feed. In the feed ingredients, the protein raw materials have been relatively scarce, and the energy raw materials are relatively loose. If the energy content is increased in the feed, the loss of the protein raw materials can be reduced, and the production cost can be reduced.
3, make up the energy content of energy and fat is more than twice as much as protein and carbohydrates, adding oil to the feed, it is easier to make up for the lack of energy in the feed.
4. Reducing pollution Adding oil and fat to the feed increases the nutrient concentration of the feed, improves the utilization rate of the feed, and reduces the pollution of the livestock and poultry excrement and the environment.
