Pig fattening is the last important part of pig production, and it is also the ultimate goal of pig production. Its central task is to use the pig's growth and development laws, apply scientific feeding management techniques, and use the least amount of input to improve pork quality, maximize pork production, and increase the economic benefits of pig production. In the breeding process of growing pigs, the following nutritional needs need to be strengthened. Energy energy is one of the most important nutrients for finishing pigs. Generally, the higher the energy level, the faster the pig's daily weight gain and the higher the feed utilization rate. The energy feed should be added. The common energy feed is mainly maize, Barley, sorghum, oats, etc. Protein protein is not only the nutrient element of muscle growth, but also the main component of enzymes, hormones and antibodies. It plays an important role in maintaining the body's life activities and normal growth and development. For the average lean-type pig diet, the crude protein level in the early stage (20 kg to 60 kg stage) is 16% to 18%, and the later stage (60 kg to 90 kg stage) is appropriate to 14% to 15%. Commonly used protein feeds include legume seeds such as soybeans, broad beans, and peas. Minerals and Vitamins The requirements for minerals in pigs are very stringent. Consider the supply of calcium, phosphorus and salt in conjunction with diets. good fresh frozen octopus Delicious Sliced Octopus,Frozen Flower Octopus,Fresh Flower Octopus,Flower Frozen Octopus Zhoushan Junwei Aquatic Products Co., Ltd. , https://www.junweiaquatic-intl.com
The amount of coarse fiber in the early stage of the coarse fiber finishing pigs should not exceed 4%, and it should not exceed 8% in the later period.
