Description
Technical field
The present invention relates to feedstuff industry, particularly relate to and a kind ofly improve feed addictive of sows farrowing ability and preparation method thereof.
Background technology
The bearing capacity of sow is one of key point of pig industry, and it directly decides production efficiency and the economic benefit of pig industry.Domestic and international sows farrowing ability has very large difference, and according to relevant data display in 2013, the such as developed country such as Denmark, America and Europe sow annual provided piglet number more than 24; And Chinese live pig is delivered for sale and is about 7.19 hundred million, sow amount of livestock on hand is about 5,100 ten thousand, and annual provides piglet number at about 14.1, and domestic and international sow annual provides piglet number to differ more than 9.9.
Affect the many factors of sows farrowing ability, as feed formula, breed difference, aquaculture management, disease etc., wherein feed formula is one of factor of most critical.According to statistics, within 2013, national pig feed total output reaches more than 8,000 ten thousand tons, wherein more than 500 ten thousand tons, sow material, therefore promotes feed formula by the research and development of feed addictive and have great market significance to raising sow material use value.Practitioner has use feed addictive to promote sow material formula all the time, attempt to solve sows farrowing capability problems, and by adding antibiotic, Chinese herbal medicine, probiotics, functional additive in a large number, or even hormone solves problem, but effect is unsatisfactory, although partial solution has certain effect, fail effectively to promote also deficient in stability.
Concrete limitation is as follows:
Use antibiotics to carry out medicinal health-care in a short time, to lifting sows farrowing ability, there is certain effect, but antibiotic is mainly through liver metabolism, RE, sow body is not only caused to produce a large amount of antibody-resistant bacterium after Long-Time Service, also can produce direct or indirect impact to sow genitals system, cause degradation problem under sows farrowing ability;
Chinese herbal medicine is one of focus of feed addictive research in recent years, has effect of many uniquenesses, but the Chinese herb feed additive that current domestic sow material uses often faces, and medicament categories is too much, the compatibility problems such as science, use amount are comparatively not large, palatability is poor; If Chinese Patent Application No. is 201210377192.9, patent name is a kind of feed addictive improving Suprapubic arch sling reproductive performance, by comprise actinolite, Chen Aiye, saline cistanche, prepared rhizome of rehmannia, rhizoma cyperi, Radix Angelicae Sinensis, Rhizoma Sparganii, the bark of eucommia, fennel and the fruit of glossy privet raw material be prepared from.This technical scheme is the combination of full Chinese herbal medicine, does not make full use of the synergy between Chinese herbal medicine and non-Chinese herbal medicine; Secondly prepared rhizome of rehmannia and rhizoma cyperi can produce bitter substance after decocting, but without any subsequent treatment improving palatability in scheme, can affect product palatability;
Probiotics has the effect of regulating intestinal canal, develop immunitypty, the comprehensive reproductive performance of lifting, but domesticly used at present mostly be traditional probiotics, as the multiplex Bacillus acidi lactici of probiotics and bacillus subtilis in the additive of existing lifting sows farrowing ability, wherein Bacillus acidi lactici non-refractory, in mixed feed pelletization, loss late is at 30%-60%, and Bacillus acidi lactici resistance is poor, culture presevation, transport all bring certain trouble;
