Embodiment 1

[0022] The raw material ratio of the Chinese herbal medicine additive is as follows: 8 parts of Huoxiang, 5 parts of Poria cocos, 4 parts of Ophiopogon japonicus, 6 parts of hawthorn, 4 parts of cassia seed, 3 parts of reed root, 5 parts of mint leaves, 5 parts of gentian, and loofah peel 6 parts, 3 parts Acanthopanax, 4 parts Yinqiao, 3 parts licorice.

[0023] The preparation method of the anti-heat stress feed additive for pregnant sows comprises the following steps:

[0024] (1) Weigh the raw materials of traditional Chinese medicine, mix them, add 6 times the total weight of raw materials of traditional Chinese medicine, soak for half an hour, heat and extract, the extraction time is 2 hours, filter, add water 6 times the total weight of raw materials of traditional Chinese medicine to extract, extract The time is 2 hours, filter, and combine two filtrates;

[0025] (2) The obtained filtrate is concentrated under reduced pressure, dried and pulverized to obtain a Chinese...

Embodiment 2

[0029] The feeding test was carried out with the anti-heat stress feed additive prepared in Example 1.

[0030] In a pig farm in Hebei, 48 sows with the same parity in the late pregnancy (89 days after mating) were selected and randomly divided into two treatments, 24 in each group. The control group was fed with corn-soybean meal based diet, The test group added 0.2% of the anti-heat stress feed additive prepared in Example 1 on the basis of the control group. The test period was from 89 days to 21 days after weaning. The inspection indicators included the litter size of sows, the number of live piglets, the birth weight of piglets, the time interval from weaning to estrus of sows, and the weaning litter weight (results are shown in Table 1).

Abstract

The present invention relates to an anti-heat stress feed additive for pregnant sows, wherein a Chinese herb additive, sodium bicarbonate, citric acid, lysine, aminobutyric acid, fructooligosaccharide and wheat bran are used to prepare the anti-heat stress feed additive. With the anti-heat stress feed additive of the present invention, the problems of heat stress and constipation of pregnant sows can be effectively alleviated, the sow feed intake can be increased, the embryonic death caused by heat stress can be prevented, and the litter size is increased.

Description

technical field [0001] The invention relates to the field of animal feed additives, in particular to an anti-heat stress feed additive for pregnant sows. Background technique [0002] The sow's gestation period is from the fertilization of eggs to the end of farrowing, with an average of 114 days (111-117 days). The growth and development of the fetus depends entirely on the mother. The feeding and management of pregnant sows is directly related to the growth and development of the embryo, litter size, birth weight, survival rate of piglets, daily gain, lactation ability and estrus breeding in the next cycle. Good feeding and management of pregnant sows can increase the weight of sows during pregnancy, ensure good fetal growth and development, minimize the death of embryos, and produce piglets with a large number of heads, large birth weight and strong vitality. Pigs have healthy body condition and good lactation performance after delivery, thereby improving the production ...
