Early weaning piglet diet formulation
Early weaned piglets diets are generally prepared according to age and body weight. The first stage: weaning to 7 kg body weight, this stage of training slot + milk replacer. The early weaning piglets should first feed milk substitutes and gradually transition to milk replacer+cutter materials, and gradually increase the ratio of teaching materials, use 10 to 15 days, and then gradually transition to teaching materials. The feed content of the chute is mainly about 15% of extruded soybean meal, about 30% of whey powder, 1.5% of sprayed plasma protein powder, 20% of lactose, addition of growth promoters, and about 35% of expanded corn; high-concentration diets Nutrition: crude protein 20% -22%, lysine 1.38%, digestive energy of 3450-3600 kcal / kg. The second stage: weaning transitional material 15-28 days, diet composition: corn about 40%, soybean meal 20%-25%, spray plasma protein powder 3%-5%, whey powder 20%-25%, lactose 10% -15% Add growth-promoting agent, feed form small particles; diet nutrient concentration: crude protein 20%, lysine 1.35%, digestive energy 3450-3600 kcal / kg. The third stage: 7-12 kilograms of piglets, diet composition: 50-60% of corn, about 25% of soybean meal, spray plasma protein powder 5%, whey powder 15%-20%, add growth-promoting agent, granular material injection Feeding; dietary nutrient concentration: crude protein 20%, lysine 1.10%, digestive energy of 3450-3600 kcal / kg. Stage IV: 12-20 kg of piglets, diet composition: more than 65% of corn, about 25% of soybean meal, plasma protein powder 5%, whey powder 15%, material type as granular material or powder; dietary nutrient concentration: Crude protein 18% -20%, lysine 1.00%, digestive energy of 3350-3 450 kcal / kg. In early weaning pig diets, a small amount of antibiotics can be added to promote piglet growth, and 0.9% to 3% of mixed acid can be added, which can effectively improve intestinal pH, which is beneficial to the growth of beneficial bacteria and is beneficial to the health of pigs.
"Steroids are a general term for a large group of derivatives widely distributed in the biological world, which can also be called steroidal or steroidal compounds. Steroid hormones are mainly synthesized and secreted by various parts of the body, and a small part can be synthesized artificially. They play an important auxiliary role in the functional activities of organs, tissues and cells of the body. Steroid hormones mainly include adrenal cortical hormones secreted by the adrenal cortex and gonadal secretion of sex hormones, when taking a large number of steroid hormones, will produce swollen face, nausea and other side effects
