The volume should be appropriate
Excessively large feed composition will cause too much burden on the digestive tract of livestock and poultry, which will affect the digestion and absorption of feed. When the volume is too small, even if the nutrients meet the needs of livestock and poultry, the livestock and poultry do not eat enough to satisfy the fullness of livestock and poultry. Abdominal sensation, therefore, is also not conducive to normal growth and development. Therefore, the feed composition volume should be adapted to the digestive tract of livestock and poultry.
Raw materials must be diverse
When formulating compound feed, the raw materials shall not be less than 4 kinds in general. Only a certain amount and type of raw materials can be combined to achieve mutual complementarity of nutrients and improve the utilization of feed. Self-made compound feeds should generally be prepared with sufficient raw materials: energy feeds such as corn, dried sweet potatoes, sorghum, etc.; protein feeds such as fish meal, bean cakes, peanut cakes, rapeseed cakes, cottonseed cakes, etc.; mineral feeds such as bone meal, shell powder , stone powder, salt, etc.; bran feed, such as bran, sweet potato powder, peanut meal, etc. The raw materials used need to be fresh, non-toxic, non-deteriorating, good palatability, and have no adverse impact on the quality of livestock and poultry products. For certain toxic feeds such as rapeseed cakes, cottonseed cakes, etc., they must be detoxified before use.
Standards are suitable
Feeding standards are based on a large number of repeated scientific tests and production verification results. For animals of different species, sex, age, weight, production use, and production level, the daily energy, protein, vitamins, and minerals of each poultry are specified. The supply of other nutrients. When rearing households with self-provisioned feed, they should choose appropriate breeding standards according to the specific conditions of the livestock and poultry they support. According to the production practice, the proportion of various types of feed in pigs and chickens' compound feed: energy feed 55% to 65%, protein feed 10% to 20%, mineral feed 1% to 7%, salt 0.3% to 0.5% , Bran, sweet potato meal feed 10% to 30%.
Matching is reasonable
Feed additives are various amino acids, vitamins, minerals and antibacterial agents added to the feed. There are two commonly used categories: one is a nutritional feed additive, including amino acids, vitamins and trace elements additives, etc., and its role is to supplement the lack of nutrients in the feed. One is to promote metabolism such as antibacterial agents, hormones, insect repellents, and Chinese herbal feed additives, etc. Its role is to stimulate the growth of livestock and poultry, increase the utilization of feed and the production capacity of livestock and poultry, and prevent diseases. Professional households must be properly selected according to their needs and strictly follow the instructions for use.
