Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.
The invention provides a feed additive for improving the productivity of sows, which comprises, by weight, 20-30% of N-carbamylglutamic acid, 12-20% of valine, 12-20% of nucleotide, 10-16% of L-carnitine, 15-25% of compound vitamin and 15-25% of compound plant components.
The N-carbamylglutamic acid can effectively improve the utilization rate of protein, has lower degradation rate in animal bodies, is beneficial to the balance and absorption of amino acid, saves essential amino acid, has stable physicochemical property at normal temperature and normal pressure, is convenient to store and is easy to add. Because the shortage of protein feed resources and the low utilization efficiency are bottlenecks which plague the development of animal husbandry, the improvement of the utilization rate of the protein can reduce the feeding cost and protect the environment. Arginine (Arg) is often used in the prior art to improve the utilization rate of protein, and is one of functional amino acids, which is widely involved in the metabolism of body tissues and closely related to the protein metabolism, immunity and the like of the body. The arginine is expensive and is very easy to degrade in animal bodies, so the dosage of the arginine is relatively large, and the effective dosage of the N-carbamylglutamic acid used in the application is about one tenth of the relative cost of the arginine.
Valine in this application is a branched amino group. One of the acids (BCAAs), is also one of the essential amino acids of pigs. Among all amino acids, valine is an amino acid having the highest oxidation rate in mammary tissue, and as the milk yield of sows increases, the demand for valine of sows is likely to increase. According to the application, the valine demand of the lactating sow can be effectively met by setting the valine weight percent to be 12-20%.
Nucleotide is an important low molecular compound in organisms, is a precursor substance for synthesizing DNA and RNA, and has important physiological functions. The nucleotide has strong food calling effect on lactating sows, and meanwhile, the nucleotide has quick repairing effect on intestinal tracts, so that the storage of nutrient substances by the lactating sows can be improved.
L-carnitine is also called carnitine, and can promote lactation of sows by supplementing L-carnitine in the lactation period of sows, and meanwhile, the L-carnitine has certain influence on the concentrations of protein, fat and lactose in colostrum, so that the nutrient content of milk is improved.
The addition of the compound vitamin can meet the vitamin requirement of the sow and improve the immunity of the sow. Specifically, in the present application, the following components are included in each kilogram of the multivitamin: 2000000-3000000IU vitamin A, 1000000-1500000IU vitamin D3, 600-1000mg vitamin E, 200-300mg vitamin K3, 800-1200mg vitamin B1, 1300-1600mg vitamin B2, 15000-20000mg vitamin B6, 15-20mg vitamin B12, 2500-3500mg pantothenic acid, 15000-20000mg nicotinamide, 130-180mg folic acid, 3000-3500mg taurine and 100-200mg biotin.
Preferably, the vitamin complex comprises the following components per kilogram: 2200000-.
The compound vitamins in the proportion can balance the nutrient components of the sows and effectively supplement the vitamins.
In addition, the composite plant component provided by the present application comprises cowherb seed, four-leaf ginseng, codonopsis pilosula, motherwort herb, astragalus and glossy privet fruit. Wherein, the organic matters (polysaccharide, polyphenol, flavone, alkaloid, volatile organic acid, etc.) of the composite plant components can greatly inhibit harmful bacteria and viruses, resist inflammation and oxidation in vivo, and improve the anti-stress and health of sows. In particular, the cowherb seed and the four-leaf ginseng are used as main medicines, and have the effects of clearing away heat and toxic materials, promoting blood circulation, removing blood stasis, enhancing mammary gland development, stimulating the menstrual flow and promoting lactation. The codonopsis pilosula and the motherwort are ministerial medicines and can nourish blood, promote lactation and promote milk secretion. The astragalus root which has the functions of nourishing blood, benefiting qi and improving immunity is taken as an adjuvant, and the glossy privet fruit is taken as a guide to coordinate with the medicaments so as to achieve the effects of enriching blood, removing stasis, dispelling wind, dredging collaterals, promoting the production of body fluid, quenching thirst, restoring menstrual flow and promoting lactation.
The inventor researches and discovers that the components have better lactation effect when being matched according to a specific weight ratio. Specifically, in the application, the weight ratio of the cowherb seed, the four-leaf ginseng, the codonopsis pilosula, the motherwort herb, the astragalus mongholicus and the glossy privet fruit is 18-25: 10-15: 18-25: 15-25: 18-28: 8-15.
Preferably, the feed additive for improving the productivity of the sows, which is provided by the application, comprises 22-28% of N-carbamylglutamic acid, 13-15% of valine, 13-15% of nucleotide, 10-16% of L-carnitine, 15-18% of compound vitamin and 15-18% of compound plant components in percentage by weight.
The feed additive for improving the productivity of the sows is used as an additive in feed, and the addition amount of the feed additive in the basal ration of the pigs is 1-5 kg/t.
In addition, the invention also provides a preparation method of the feed additive for improving the production performance of the sows, which is characterized in that the raw materials are directly and uniformly mixed, and the components of the composite plant components are crushed into superfine powder and then mixed, so that the utilization rate and the absorption rate of the composite plant components can be effectively improved by the superfine powder.
