Description
Technical field
The invention belongs to field of fodder, particularly a kind of in-pig mixed feed and preparation method thereof.
Background technology
The production performance performance of sow directly affects the benefit of raising pigs.In China; no matter be large-scale pig farm or middle-size and small-size pig farm or professional raiser; all have in various degree the low problem of sow production performance, as not up to standard in constipation, body condition, out of heat, not obvious, nonpregnant, the miscarriage of postponing to oestrus, to oestrus, lactation are few etc.These problems are all closely related with the nutritional need of sow, and 114 days sow gestation phases, whole process is fed and is divided into early stage, mid-term, later stage three phases.The feeding capacity in each stage must strict be controlled, and should satisfy embryo growth and development, also to satisfy sow self and keep, for sows in perinatal period ready.Rise since on January 1st, 2013, European Union's regulation large-scale pig farm gestation, milking sow ban use of the position limiting fence setting, but this animal welfare measure also is difficult to promote in China in a short time.The time of sow gestation phase 90% will be spent in position limiting fence, and serious constipation phenomenon appears in sow, except the cause of above-mentioned gestation, and does not move for a long time, and the enteron aisle dehydration also has much relations, so prevention of sow constipation is a technical barrier that needs to be resolved hurrily.Acidulant can improve the local flavor of feed, covers in feed because having added the bad smell after the minerals and vitamins, increases the interest of searching for food of sow, replenishes that the gastric acid secretion that causes because of gestation is not enough waits effect.But add the acidulant without protection in sow feed, all acid all can discharge under one's belt, can suppress on the contrary the function of sow secretion acid itself, and most of acid also may be neutralized by the alkali in feed in addition.
At present internal feed factory only adds acidulant in sucking pig and nursery-stage pig feed, and sow and growing-finishing pig use less, and the quality of acidulant is very different.General acidulant kind is single, and irritant smell, and compound acidulant is fed and can not be arrived enteron aisle fully, and action effect is not good.
Use the existing long time of Chinese herbal feed additive in livestock-raising, Chinese herbal medicine stimulates little to animal, safety, and noresidue, and more easily buying, cost is low, and preparation is simple.Multiple Chinese herbal medicine is used in conjunction with can bring into play drug effect jointly.
