Embodiment 1

[0012] A gestation feed for sows, consisting of the following components by weight percentage:

[0013] 50.8% corn, 8% soybean meal, 35% bran, 2% konjac flour, 1% calcium carbonate, 0.5% calcium hydrogen phosphate, 0.5% table salt, 0.2% antifungal agent and 2% Trace element premixes,

[0014] The trace element premix contains 10 mg of copper; 100 mg of iron; 30 mg of manganese; 60 mg of zinc; 0.6 mg of iodine; 0.25 mg of selenium; 2.24 mg of vitamin A; Vitamin B22mg; Vitamin B61mg; Vitamin B120.014mg.

Embodiment 2

[0016] A gestation feed for sows, consisting of the following components by weight percentage:

[0017] 54.2% corn, 10% soybean meal, 30% bran, 2.2% konjac flour, 1.1% calcium carbonate, 1% calcium hydrogen phosphate, 0.4% table salt, 0.1% antifungal agent and 1% Trace element premix.

[0018] The trace element content in the premix is ​​the same as in Example 1.

Embodiment 3

[0020] A gestation feed for sows, consisting of the following components by weight percentage:

[0021] 52.75% corn, 15% soybean meal, 25% bran, 3% konjac flour, 2% calcium carbonate, 1.5% calcium hydrogen phosphate, 0.2% table salt, 0.05% antifungal agent and 0.5% Trace element premixes,

[0022] The trace element content in the premix is ​​the same as in Example 1.

[0023] Physicochemical properties and fermentability of embodiment 1-3 feed:

[0024] 1. Determine the viscosity (mPa·s), water swelling (ml / g) and water binding capacity (g / g) of the feed using the methods in the reference literature.

[0025] 2. The reference method was used to determine the concentration of short-chain fatty acids produced by in vitro fermentation of feed.

[0026] The results are shown in Table 1:

Abstract

The invention discloses a feed for breeding sows at a gestation period. The feed is composed of following components in percentage by weight: 50-60% of corns, 8-15% of soya bean meal, 25-35% of bran, 2-3% of konjaku flour, 1-2% of calcium carbonate, 0.5-1.5% of calcium hydrogen phosphate, 0.2-0.5% of table salt, 0.05-0.2% of a mildew preventive and 0.5-2% of a microelement premix. The feed disclosed by the invention has very high viscosity, water absorption expansibility, water binding force and fermentation property, and is suitable for pregnant sows; the feed intake of the breeding sows at a lactation period can be obviously improved; the feed is good for improving the individual weight and the litter weight of piglets and is an effective manner for improving the fertility of the breeding sows; the great economic benefits can be brought to the production of large-scale pig farms.

Description

technical field [0001] The invention belongs to the field of feed, in particular to a feed for sows during pregnancy. Background technique [0002] The nutrient intake of sows during lactation has a significant impact on the growth and survival rate of piglets, the litter size of the next litter, and the interval between weaning and estrus of sows. However, due to the low feed intake of sows during lactation, the nutrient intake Insufficient income leads to generally low reproductive capacity of sows, which directly affects the economic benefits of large-scale pig farms. According to statistics, the number of weaned piglets provided by sows in my country's large-scale pig farms is about 17, which is lower than the average level of foreign large-scale pig farms. [0003] At present, there are two main ways to increase the nutrient intake of lactating sows: one is to increase the concentration of dietary nutrients by adding fat to the lactation ration or increasing the protei...
