Embodiment Construction

[0017] A feed for pregnant sows that increases the birth weight of piglets. The weight (jin) of each raw material component is: charcoal 60, montmorillonite 60, isatis root 40, iron horsewhip 10, salvia miltiorrhiza 30, shrimp shell 30, big belly skin 40 , Wujiapi 30, wolfberry leaves 10, Jianqu 60, hawthorn 60, red dates 30, green tea 10.

[0018] Take each raw material according to the above weight, and stir the above raw materials evenly. When feeding pregnant sows, the feed is mixed into daily pig feed to obtain mixed feed for pregnant sows, and the added amount of the feed is 1.5-1.7% of the weight of daily pig feed. The daily intake of pregnant sows is more than 2 kg of mixed feed, and the amount is gradually reduced to 0 kg three days before farrowing.

[0019] In order to verify the feeding effect of the formula of the present invention for pregnant sows, a 4-month feeding test was carried out in the farmer's pig farm. The experiment adopted a single-factor comparati...

Abstract

The invention discloses pregnant sow feed capable of improving piglet birth weight. The pregnant sow feed comprises, by weight, 50-70% of charcoal, 50-70% of montmorillonite, 30-50% of isatis root, 5-15% of lespedeza pilosa, 20-40% of salvia miltiorrhiza, 20-40% of shrimp shell, 30-50% of pericarpium arecae, 20-40% of cortex acanthopanacis, 5-15% of boxthorn leaves, 50-70% of medicinal fermented mass, 50-70% of hawthorn, 20-40% of red dates and 5-15% of green tea. By means of adsorption and removal of toxin in pregnant sows and using of stomach invigorating crude drugs, the pregnant sow feed capable of improving the piglet birth weight enables the sows to absorb nutritional ingredients conveniently, improves immunity of the sows, and can improve number born alive of the pregnant sows and the piglet birth weight.

Description

Technical field: [0001] The invention mainly relates to the field of pig feed, in particular to a feed for pregnant sows which improves the birth weight of piglets. Background technique: [0002] With the improvement of people's living standards, the demand for livestock products continues to increase, and the breeding industry is developing in the direction of scale and standardization. However, the key to restricting the development of the pig industry at present is the low production capacity of sows. During pregnancy, the number of live piglets is small and the weight of piglets is low, resulting in a small amount of pigs and slow production speed. To increase the number of piglets born alive and the weight of piglets, it is necessary to provide sufficient nutrition for pregnant sows. Invention content: [0003] The purpose of the present invention is to make up for the defects of the prior art, and to provide a feed for pregnant sows that increases the birth weight o...
