Embodiment 1

[0031] To verify the improvement effect of a feed additive of the present invention that solves the constipation and production performance of pregnant sows on sows within one month of pregnancy, the applicant conducted a test on the effect of constipation on a pig farm in Ruicheng County. The test date is April-May 2018. The proportion of additives used is 0.30%, and the basic feed is feed for pregnant sows. The 50 newly mated pregnant sows in the control group were fed with basal feed, and the 50 newly mated pregnant sows in the test group were fed with basal feed+3.0kg / ton of additives. According to the overall body condition of the sow, the feed intake is controlled at 2.0-2.1kg. The test period is 30 days.

[0032] The experimental breeding and management were carried out in accordance with the normal norms of the farm. Record the feces of each sow every day. The criterion for judging sow constipation is that the sow pulls dry hard spherical feces. The specific manifes...

Embodiment 2

[0038] To verify the effect of a feed additive to solve the constipation and production performance of pregnant sows in the present invention on the body condition regulation effect of sows in the second trimester, the applicant conducted a test on the body condition regulation effect of sows in a pig farm in Tongguan County, Shaanxi Province. The test date is May-July 2018. The proportion of additives used is 0.30%, and the basic feed is pregnant sow feed (energy concentration 3.0MJ / kg). Select 100 mid-pregnancy (about 40 days) sows to measure backfat thickness at point P2. These 100 sows were fed with basic pregnant sow feed+2.5% feed additive of the present invention.

[0039] Measure the backfat thickness of sows at point P2 (6.5 cm from the last rib of the pig to the midline of the back). This test selects all multiparous sows. The backfat thickness in the second trimester of pregnancy should be controlled at about 19 mm. Body condition score 3 points.

[0040] The tes...

Embodiment 3

[0048] To verify the improvement effect of a feed additive for solving the constipation and production performance of pregnant sows of the present invention on the production performance of pregnant sows, the applicant conducted a test on the delivery effect on a pig farm in Weinan City, Shaanxi Province. The test date is January-May 2018. Additive use ratio 0.50%, control group, 50 farrowing sows, fed basic feed, test group, 50 farrowing sows, fed basic feed+0.5% additive of the present invention. Pregnant sows were mated to farrowing during the test period.

[0049] The test data was statistically analyzed using SPSS12.0 statistical software, and the results were expressed as "mean ± standard deviation" after single-factor variance comparison.

[0050] The test results are as follows

[0051]

[0052] Different suffix letters of data in the same column indicate significant difference (P<0.05).

[0053] The above results show that adding a feed additive provided by the ...

Abstract

The invention relates to a feed additive capable of treating constipation of pregnant sows and strengthening production properties and a preparation method of the feed additive, and belongs to the field of feed additives. The feed additive capable of treating constipation of pregnant sows and strengthening production properties comprises the following raw materials of 20-30 parts of dietary fibers, 20-30 parts of yeast culture, 10-20 parts of xylooligosaccharide, 5-10 parts of radix codonopsis, 5-10 parts of radix angelicae sinensis, 3-5 parts of bighead atractylodes rhizomes and the balance of zeolite powder complemented as carriers. The preparation method of the feed additive comprises the following steps of weighing the dietary fibers, the yeast culture, the xylooligosaccharide, the radix codonopsis, the radix angelicae sinensis, the bighead atractylodes rhizomes and the zeolite powder, crushing the weighed dietary fibers, the weighed radix codonopsis, the weighed radix angelicae sinensis and the weighed bighead atractylodes rhizomes, performing screening through a sieve, and uniformly mixing the raw materials, so that the feed additive is prepared. The addition quantity of theadditive provided by the invention to a complete compound feed in the proportion being 0.25%-0.30% during the period from the breeding of sows to pregnancy time being 90 days, and the addition quantity of the additive is 0.40%-0.50% during the period of pregnancy time being 91 days to childbirth. The palatability of the sows can be improved, the intestinal microecology of the sows is promoted to be balanced, the constipation of the pregnant sows can be prevented and treated, the body condition can be improved, and the production properties of the sows can be strengthened.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a feed additive for solving the constipation and production performance of pregnant sows and a preparation method thereof. Background technique [0002] At present, constipation in pregnant sows is ignored by managers because it does not produce direct benefits. According to the conventional feeding management process, the pregnancy period of sows is divided into the first stage: the implantation stage of fertilized eggs (gestation 0-30 days), at this time, the feeding amount should be controlled to reduce the impact of gastrointestinal peristalsis on the uterus. The second stage: sow body condition adjustment stage (gestation 31-70 days), according to sow body condition, feed reasonably. The third stage: mammary gland development stage (71-90 days of pregnancy), energy and protein requirements are sufficient. The fourth stage (91-110 days of pregnancy): the period of rapid fetal ...
