Compound feed for weaned piglets

Abstract

The invention relates to a compound feed for a weaned pig. The compound feed is prepared from the following raw materials in parts by weight: 25-40 parts of corn, 15-20 parts of extruded corn, 15-20 parts of bean pulp, 2-5 parts of whey powder, 7-11 part of soybean peptide, 2-6 parts of plasma protein powder, 1-5 parts of soya bean lecithin, 1-5 parts of palm kernel oil, 0.012-0.015 part of 5000-unit phytase, 1-2 parts of mountain flour, 0.4-0.5 part of monocalcium phosphate, 0.05-0.2 part of choline, 0.1-0.5 part of salt, 2-5 parts of saccharose, 1-3 parts of vitamin premix, 1-3 parts of microelement premix, 0.2-0.8 part of lysine, 0.1-0.3 part of methionine, and 0.1-0.3 part of threonine. The compound feed can well meet nutritional requirement of the weaned pig, improves the digestibility of the weaned pig for nutrient substance, improves the immunity of the weaned pig, promotes rapid and healthy growth of the weaned pig, and guarantees the survival rate of the weaned pig.

Description

technical field [0001] The invention relates to the field of livestock and poultry feed, in particular to a compound feed suitable for the intestinal characteristics of weaned piglets. Background technique [0002] At present, with the development of animal husbandry, my country's pig production is gradually developing in the direction of scale and intensification, and the weaning age of piglets is gradually reduced from the traditional 60 days to 35 days. The weaning age of pig farms with higher technology is about 21 days. Early weaning of piglets can increase the reproductive rate of sows, reduce the transmission of diseases from mothers to piglets, and improve the growth performance and carcass quality of piglets during the growth period. As the age decreases, the weaning syndrome of weaned piglets becomes more and more obvious. Because the digestive organs of piglets are not yet mature, the functions are not perfect, and the activity of digestive enzymes in the body is lo...

Problems solved by technology

[0002] At present, with the development of animal husbandry, my country's pig production is gradually developing in the direction of scale and intensification, and the weaning age of piglets is gradually reduced from the traditional 60 days to 35 days. The weaning age of pig farms with higher technology is about 21 days. Early weaning of piglets can increase the reproductive rate of sows, reduce the transmission of diseases from mothers to piglets, and improve the growth performance and carcass quality of piglets during the growth period. As the age decreases, the weaning syndrome of weaned piglets becomes more and more obvious. Because the digestive organs of piglets are not yet mature, the functions are not perfect, and the activity of digestive enzymes in the body is low, the digestion, absorption and utilization of protein and fat containing long-chain fatty acids The rate is poor, small peptides composed of 2-3 amino acids and fats rich in medium and short-chain fatty acids can be better digested and absorbed, and directly enter the tissue for utilization, resulting in poor digestion and stress resistance of piglets, loss of appetite, A series of problems such as digestive disorders, diarrhea, and low feed utilization
