Description
Technical field
The invention belongs to sow feed technical fields, and in particular to a kind of sow feeding mould for improving sow reproductive performance
Formula and matched sow feed.
Background technique
In recent years, with the continuous development of the research of domestic and international pig breeding technology and deeply, the reproductive performance of sow is obtained
It is obviously improved.Especially in terms of the Farrowing Traits of sow, by 10-11 piggys of past one viviparity of sow promoted to
14-15 piggys.At the same time, the raising and improvement of pig industry feeding and management level are but also above-mentioned sow reproductive performance is latent
Power is more fully played.However, another direction of pig breeding technology is the lean meat percentage for improving market pig, the thickness of backfat is reduced
Degree, under the influence of this Breed dirction, the back fat deposition capability of the sow of current many outstanding kinds is also declined, and state
Outer many research and practice have shown that, suitable sow back-fat thickness is presented with extremely strong correlation with its reproductive performance.Therefore,
The nutrition of high yield sow and feeding management scheme are also required to correspondingly make improvement and optimization.
In addition, finding in the physiology of pig and nutrient research field, the 0-30 days stages of sow gestation early stage are embryo's hairs
The critical period educated and survived.It can promote to secrete the special egg in more uterus in sow body by the supply of low nutrition concentration in this stage
White, this Special Proteins have the function of significantly protecting embryo survival.Based on this research mechanism, raised in traditional sow
Strictly limit would generally be carried out in management mode, in 0-30 days after sow gestation to pregnant sow to raise, daily pregnant sow is raised
The scale of feeding of material is only 1.8-2.0kg or so.This traditional sow feeding mode is for the sow of lower reproductive performance
Survival rate of embryo can be effectively improved to improve litter size, but its nutrition for the sow of high reproductive performance of this mode
Supply amount can wretched insufficiency, and according in recent years research discovery sow gestation be in early days back fat restore best period,
Therefore the too low scale of feeding of First Trimester also can further influence the efficiency that entire gestation backfat restores.In addition, from health and
For the angle of animal welfare, traditional agent of feed for pregnancy sow nutrition design and too low scale of feeding also result in sow enteron aisle and are good for
Kang Du is difficult to maintain, it is easier to constipation and the accumulation of vivotoxin occur, so that sow reproductive life and breeding achievement are by shadow
It rings.
Based on the above background, a kind of feeding management mode for being suitable for high reproductive performance sow and its mating is researched and developed
Each stage feed nutrition scheme seem particularly necessary.
Summary of the invention
The purpose of the present invention is mainly based upon the nutritional need and physiological property of current high yield sow, and it is female to provide a kind of raising
The sow feeding mode of swine reproduction performance and matched sow feed, make a set of new nutrition for more meeting production requirement and
Managed Solution, so that the reproductive performance potentiality on pig farm are able to larger play and embody, to improve culture efficiency.
Technical scheme is as follows:
A kind of sow feeding mode for improving sow reproductive performance of the present invention is as follows:
(1) pregnant sow through producing only carries out stringent limit in 0-5 days and raises, feed matched first half period of gestation after breeding
Feed, every sow feed 2.0-2.2kg daily；
Suprapubic arch sling fed matched first half period of gestation feed within the 6-50 days gestational period, and every sow feeds 2.5- daily
2.7kg；
It is to feed matched first half period of gestation feed in the 0-50 days gestational period in 0-50 days after breeding for the first-born sow,
Scale of feeding is controlled in 2.0-2.3kg.
(2) in the 51-85 days sow gestation phase (second trimester of pregnancy), matched first half period of gestation feed is fed, every sow is daily
2.3-2.5kg is fed, and monitors sow back-fat thickness with back fat instrument, is maintained at back-fat thickness within the scope of 16-18mm；For body
The sow of condition overfertilization (back-fat thickness>18mm) or excessively thin (back-fat thickness<16mm), in the basis 2.3-2.5kg scale of feeding level,
Back-fat thickness is often less than (i.e. less than 16mm) or beyond (i.e. beyond 18mm) 1mm, scale of feeding accordingly decreases or increases 0.2-0.3kg
(preferably 0.25kg), but feed intake need to be in the range of 2-3.5kg scale of feeding after adjusting.
(3) in the 86-110 days sow gestation phase (latter half of gestation), matched latter half of gestation feed is fed, every sow is daily
Feed 3.0-3.5kg feed.
(4) in the 111-115 days sow gestation phase (expected date of childbirth), matched agent of feed for nursing sow is fed, scale of feeding is from 3.0-
3.5kg starts to be reduced 0.5kg daily, until scale of feeding reduces to, 2-2.2kg is horizontal to maintain the scale of feeding to the same day of giving a birth later.
(5) first day matched agent of feed for nursing sow of feeding 2-2.2kg after Farrowing increases the food in one's mouth of 1kg daily later
Wet nurse's pannage scale of feeding comes into effect free choice feeding after reaching within postpartum the 5th day the feed intake of 6-6.2kg, is freely eaten
State maintains to 25-28 days sow postpartum to wean.
(6) enter the empty phase after milking sow wean, until 5-7 days breed next time before, latter half of gestation feed is fed,
And it is freely eaten by sow.
Innovation point of the present invention on feeding pattern essentially consists in:
(1) it is directed to sow gestation early period, distinguishes the first-born sow and Suprapubic arch sling.Suprapubic arch sling first half period of gestation is divided into two ranks
Section uses low scale of feeding 2-2.2kg, pregnant 6-50 days raising scales of feeding to 2.5-2.7kg in pregnant 0-5 days.The first-born sow, 0-50
Its scale of feeding 2.0-2.3kg.
(2) scale of feeding is improved during Suprapubic arch sling first half period of gestation 6-30 days is key technology, because of the rank under normal circumstances
Duan Tigao scale of feeding will lead to number born of sow decline, if expectation improves feed intake and do not influence litter size, even improve
If litter size, it must just be realized using fermentable fibres control technique.
(3) in pregnant 51-85 days (second trimester of pregnancy), scale of feeding is adjusted according to back fat instrument, and provide specific adjustment standard such as:
1mm back fat difference corresponds to 0.2-0.3kg (preferably 0.25kg) feed adjustment amplitude.
(4) it is directed to sows in perinatal period, there is specific feed mode standard, antenatal to be gradually reduced, postpartum gradually dosage.

It (1) is based on accurately net energy and apparent digestible lysine system, application in the formula design of first half period of gestation feed
Suitable net energy and apparent digestible lysine ratio control technique are prepared, and are come so that more nutrition are used for the recovery of sow back fat,
Rather than the growth of body.Meanwhile using the high fermentable fibres daily ration configuration technology of low nutrition concentration, so that sow is in gestation
There are early period more nutriments to absorb acquisition by the microbial fermentation of enteron aisle rear end, can obviously slow down sow feeding in this way
The infiltration rate of nutriment after daily ration plays the short-term fluctuation of insulin and blood sugar concentration in control blood, and sow
Internal insulin and blood sugar concentration are about steadily more conducive to the survival of embryo.Meanwhile lower scale of feeding is used in pregnant 0-5 days,
The generation of Gilt Uterus Special Proteins can be effectively excited and promote, to play the role of preventing miscarriage.Therefore, this nutriment is slow
The synchronization modulation technology for releasing absorption and physiological hormone can make sow equally maintain higher embryo on the basis of high feed intake
Survival rate breaches First Trimester scale of feeding in traditional feeding pattern and excessively drops so that litter size when making Farrowing improves
The problem of low survival rate of embryo.
(2) in the formula design of latter half of gestation feed, it is same based on accurately nutrition system and net energy with can digest it is bad
Propylhomoserin ratio control technique is prepared, and the nutriment in feed is made more to meet development and the late embryogenesis of sow self-reproduction organ
The dual requirements of fast-growth.In addition, feed mineral control accurate technology is applied to this stage, with pregnant age in days
In the case that the requirement of increase calcium is stepped up, the level for designing calcium in feed just meets 110 days gestational periods sow to calcium
Requirement, and slightly below gestation daily requirement during 111-115 days can shift to an earlier date 3-5 days and allow sow body antenatal in this way
Start to employ the calcium in bone inside to meet the requirement of pregnant final stage embryo fast-growth, sow employs bone after childbirth
The efficiency of bone calcium is directly in higher level, so as to avoid just starting gradually to employ caused by the calcium in bone after childbirth
Postpartum paralysis and postpartum milk is hydropenic happens.
(3) in the formula design of agent of feed for nursing sow, using fatty acid control technique, by agent of feed for nursing sow
Adipose-derived regulation improves unsaturated fatty acid especially linoleic acid content, and using linoleic acid content as matching
Square nutritive index sets minimum limit value, to ensure that corresponding fatty acid composition more efficiently can utilize conversion by sow in feed
For the composition of breast milk, while it can also promote the output of milk of sow.
