Problems solved by technology

[0004] Lack of nutrition in lactating sows will lead to a decline in the quality and quantity of milk, poor disease resistance, diarrhea, and high mortality in piglets, and the weaning weight of surviving piglets is small, which affects post-weaning growth
At the same time, sows lose a lot of body reserves during lactation, which prolongs the time of estrus after weaning, which directly leads to a longer production cycle, which affects the number of annual litters

[0033] The preparation method of fresh-keeping feed for lactating sows of the present invention, it comprises the steps:

[0034] (1) Preparation of fermented and acidified feed: crush corn and soybean meal until the particle size is less than 2mm, then mix corn, soybean meal, fermentation broth and water evenly according to the formula ratio, and carry out airtight fermentation at 20-30°C until the acidity (with pH value meter) when it reaches less than 4.5, vacuumize the package;

[0035] (2) Preparation of powdery premixed feed: mix bran, soybean meal, stone powder, calcium hydrogen phosphate, salt, baking soda, antioxidant, super sweetener, choline chloride, lysine, Virginia The mycin, enzyme preparation, vitamin premix and trace element premix are evenly mixed and packaged;

[0036] (3) Mixing: mixing the prepared fermented acidified feed and powdery premixed feed to prepare the fresh-keeping feed for lactating sows.

Embodiment 1

[0038] Preparation of fermented and acidified feed: Grind 30% corn and 40% soybean meal until the particle size is less than 2mm, then mix 30% corn, 40% soybean meal, 0.05% fermentation liquid and 29.95% water according to the formula ratio, and put them under the condition of 20-30℃ Carry out airtight fermentation under the hood, and carry out vacuum packaging when the acidity (in terms of pH value) reaches less than 4.5;

[0039] Preparation of powdery premixed feed: 7.7% bran, 10% soybean meal, 25% stone powder, 30% calcium hydrogen phosphate, 15% salt, 2.0% baking soda, 0.1% antioxidant, 0.2% super sweetener, 3.5% choline chloride, 1.5% lysine, 0% virginiamycin, 0% enzyme preparation, 1.0% vitamin premix and 4.0% trace element premix are evenly mixed and packaged;

[0040] Mixing: the prepared fermented acidified feed and powdered premixed feed are mixed according to the weight ratio of 4:3 to prepare the fresh-keeping feed for lactating sows.

Abstract

The invention aims to disclose freshness-retaining feed for lactating sows and a preparation method thereof. The freshness-retaining feed for lactating the sows is formed by mutually mixing fermented acidulated feed with powdery pre-mixture feed, wherein the weight ratio of the fermented acidulated feed to the powdery pre-mixture feed is 4: 3; compared with the prior art, when the obtained freshness-retaining feed is used for feeding the sows, the feed is sour and sweet in taste and good in food calling effect, and the sow has healthy intestinal canal and small possibility of constipation; besides, the sow is high in daily feed intake during lactation period, good in body condition, good in milk quality and high in quantity; roasters are healthy, high in rate of survival and high in weaning weight. Furthermore, the sow is low in weight loss and short in heat interval after weaning; and therefore, the purposes of the freshness-retaining feed are achieved.

Description

technical field [0001] The invention relates to a fresh-keeping feed and a preparation method thereof, in particular to a fresh-keeping feed for lactating sows and a preparation method thereof. Background technique [0002] my country is the largest pig raising country in the world. However, in terms of production level, there is still a big gap with countries such as Europe and the United States. Taking the number of weaned piglets provided per sow as an example, the current average level in my country is about 20, while that in Europe and the United States can reach 30, and better ones can even reach more than 35. [0003] There are three factors that affect the number of weaned piglets provided by sows per year: one is the litter size of sows, the second is the survival rate of piglets, and the third is the number of litters per year. As far as the litter size of sows is concerned, the level between my country and foreign countries is not much different, and the litter s...
