Embodiment 1-5

[0035] Select 48 grown binary sows with 75 days of gestation, and randomly divide them into 6 groups. The diets of each group are added according to the weight of the components of each premix in Table 1. The feeding time is 39 days (75 days - parturition). Each experimental sow is injected with 20-30 units of oxytocin at parturition. After about 10 minutes, 50 ml of milk samples are collected, centrifuged at 3000 g for 30 minutes, and the skim milk is stored in a refrigerator at -20 ° C. As a spare, the levels of prolactin (PRL) and growth hormone (GH) in milk were measured by radioimmunoassay, and the kit was provided by Nanjing Jiancheng Bioengineering Institute. The sows drank water freely, and recorded the litter size, birth weight and weaning weight of the sows respectively. The test results are shown in Table 2.

Embodiment 6

[0047] This embodiment is used to improve the premix of sow production performance. The premix includes the following components and the content of parts by weight in 1000 parts by weight: 23 parts of arginine, 7 parts of L-carnitine, 10 parts of folic acid, 8 parts of fructo-oligosaccharide, 110 parts of astragalus polysaccharide, 105 parts of glyceryl butyrate, 100 parts of Bifidobacterium bifidum probiotic powder, 0.15 part of chromium picolinate, and the rest as carrier.

[0048] Among them, the effective live bacteria content of Bifidobacterium bifidum probiotic powder is ≥2.5×10 6 CFU / g. The mass content of the active ingredient in the chromium picolinate is ≥99%, the mass content of the chloride is ≤0.03%, and the loss on drying of the chromium picolinate is ≤2%.

Abstract

The invention relates to a premix for improving the production performance of a sow as well as a preparation method and application of the premix. The premix is prepared from the following components in parts by weight: 10-30 parts of arginine, 5-12 parts of L-carnitine, 1-15 parts of folic acid, 5-20 parts of fructose-oligosaccharide, 50-150 parts of astragalus polysaccharide, 50-150 parts of butyrin, 50-120 parts of bifidobacterium bifidum probiotic powder, 0.1-0.2 part of chromium picolinate and the balance of carrier based on 1,000 parts by weight, wherein the premix is added to a basic ration of the sow at 1-4% of total mass of the basic ration of the sow. Compared with the prior art, the premix has the advantages that the sow feed intake and the lactation yield can be effectively promoted by the premix; the weight loss and the backfat loss of the sow at the lactation period can be reduced; the heat interval after weaning is shortened; the whole production performance of the sow is improved; and the problems of insufficient sow feed intake, insufficient milk, postpartum diseases and low production performance are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of pig breeding, and relates to a premix for improving the production performance of sows, a preparation method and application thereof. Background technique [0002] Intensive, standardized and large-scale farming has become the main development direction of the pig industry at home and abroad. The rapid development has also caused a series of problems, among which sow PSY and sow nutrition are increasingly concerned by people. Modern sow breeding also has more demanding nutritional requirements, which makes sow feeding the key link that requires the most advanced technology in modern pig production; at the same time, the pressure to increase milk production makes sows more and more trapped in nutritional stress , The satisfaction of nutrition directly affects the full play of its reproductive potential. [0003] The physiological factors affecting sow production performance are very complex. Therefore, it...
