Feed for improving lactation capacity of lactating sows and preparation method of feed

Abstract

The invention discloses a feed for improving the lactation capacity of lactating sows and a preparation method of the feed. The feed is prepared from the following raw materials in parts by weight: 30-40 parts of corn, 20-30 parts of bran, 10-15 parts of sorghum bran, 5-10 parts of olive cake, 3-6 parts of yolk powder, 4-8 parts of corn glucose residue, 3-5 parts of cowherb seed powder, 2-4 parts of barley pest powder, 5-10 parts of bermuda grass, 8-14 parts of lespedeza bicolor leaf, 10-15 parts of malachium aquaticum, 4-8 parts of sesame leaf, 3-4 parts of cane molasses, 2-3 parts of grapefruit juice, 4.5-6.5 parts of squid organ meal, 6-9 parts of black ant powder, 0.4-0.8 part of radix scrophulariae leaf powder, 0.3-0.6 part of moringa seed powder, 0.2-0.5 part of ginseng powder and 3-5 parts of modified mountain flour. The feed disclosed by the invention is good in palatability, and is capable of improving the diet intake of the lactating sows, ensuring that the lactating sows absorb enough nutrient elements such as energy, proteins, vitamins, mineral substances and the like, significantly improving the lactation capacity of the lactating sows, ensuring enough milk amount and good milk quality, improving the weight of weaning litter and the survival rate of piglets, reducing the weight loss of the lactating sows in the lactation period, and promoting normal oestrus, ovulation and further pregnancy of the lactating sows after nursing, so that the market value is great.

Description

technical field [0001] The invention relates to a feed for improving lactation ability of lactating sows and a preparation method thereof, belonging to the technical field of feed. Background technique [0002] In recent years, with the rapid development of the pig industry, single feed has been increasingly unable to meet the nutritional needs of pig growth. Therefore, in the development of aquaculture production, rational use of limited feed resources, changing the traditional single feed feeding method, adopting scientific and reasonable compound feeds, and scientific feeding can improve breeding benefits. [0003] The feeding management of lactating sows plays a pivotal role in the whole process of sow feeding and management, and its management level directly affects the production efficiency of the whole pig farm. According to the characteristics of the nutritional needs of lactating sows, we know that in addition to maintaining normal metabolism and growing body tissu...

Problems solved by technology

Negative nutritional balance during lactation will lead to reduced milk production of sows (especially primiparous sows) and affect the production performance of the next reproductive cycle. Insufficient intake of energy, protein, amino acids, vitamins and minerals during lactation will lead to lactation Lack of milk, less milk, poor milk quality, excessive weight loss, prolonged post-weaning estrus interval and low mating conception rate and other reproductive obstacles in sows increase the culling rate of sows
