Abstract
The present invention provides a kind of coconut oil micro-capsule fatty powder and the applications in the big perinatal period daily ration of sow.Coconut oil micro-capsule fatty powder of the invention can improve sow in big perinatal period negative energy balance, quickly provide energy for sow, will not cause the excessive fat deposition of sow antenatal, in postpartum raising feed intake, will not excessively lose flesh, to improve sow Growth Results.
Description
Technical field
The present invention relates to field of feed, particularly, are related to a kind of coconut oil micro-capsule fatty powder and enclose production greatly in sow
Application in phase daily ration.
Background technique
Sow big perinatal period refers to what sow bred from latter half of gestation (pregnancy 86 days or 90 days) to sow postweaning estrus
This period.This period management target is to make sow secure delivery, smoothly farrowing, fecund young, lactation living and promote sow postpartum extensive
It is multiple to breed again.Sow gestation later period fetus Rapid development is higher to energy nutrient material requisite, therefore needs to attack in actual production
Tire attacks tire and generally uses lactation material.On the one hand meets the needs of fetus Rapid development is to energy nutrient as far as possible when attacking tire, but another
Aspect controls the body fat over-deposit of sow as far as possible again.For both balances, the energy of sow is to be in negative balance state,
In addition sow also meet with it is various stress (environmental management stress, childbirth stress wait), consumption energy stress be also required to resist.It is female
The childbirth of pig is a very complicated process, and which includes the contraction of uterine smooth muscle, the contraction of muscle is to need energy
It maintains, and needs energy supply form faster.The sow for closing on term reduces insulin sensitivity, insulin resistance
Can gradually increase, cause maternal tissue for glucose utilization rate reduce, energy nutrient state occur negative balance (Zeng Lingyi,
2016).Long-term negative energy balance causes sow stages of labor too long (especially farrow more sows), sow postpartum fatigue, in turn
Resistance, which is deteriorated, easily occurs hysteritis, mammitis, shows as sow postpartum anorexia, milk quality variation piglet white scour, sow falls
Fat, the inter oestrual period time is long again after wean.In addition, piglet struggles in birth canal since stages of labor is too long, more energy is consumed,
To influence piglet vigor of being born, the teat that piglet competition has sufficient breast milk is influenced, piglet slow growth is eventually led to and survives
Rate decline.In the production of modern intensive sow, common about 8% birth piglet because in sow birth canal anoxia asphyxia due to it is dead,
These stillborn foetus numbers account for the 20-25% of dead piglet sum in 3d after birth.
Currently, for mainly passing through because the problems such as stages of labor caused by the big perinatal period negative energy balance of sow is too long in production
Treated and prevented using medicated premix postpartum fatigue brought by a series of defect, without specially with feed link overnutrition source with
The adjusting control of trophic level carrys out shortening labor, relieves fatigue, alleviates disease symptoms and influence degree.The present invention is big for sow
Perinatal period physilogical characteristics and its crucial feeding objective, need feature in particular for energy nutrient demand and fat, big in sow
Coconut oil micro-capsule fatty powder is added in perinatal period daily ration, is balanced long chain fatty acids and medium chain fatty acid, is quickly energized, mainly solve
Because the sow gestation later period attack tire it is unreasonable it is equal caused by energy deficiency, overfertilization, digestive disorders, and lead to that sow stages of labor is too long, production
The problems such as anorexia, sow milk are bad afterwards, postweaning estrus postpones.
Summary of the invention
It is an object of that present invention to provide a kind of coconut oil micro-capsule fatty powder and in sow big perinatal period, (the sow gestation later period is attacked
Tire to sow postweaning estrus is bred) application in daily ration, with solve to attack because of the sow gestation later period tire it is unreasonable it is equal caused by energy
Measure deficiency, overfertilization, digestive disorders, and cause sow stages of labor it is too long (first piglet of Farrowing to afterbirth be completely exhausted out when
Between), the technical problems such as bad, the postweaning estrus delay of postpartum anorexia, sow milk.
It to achieve the above object, is by following weight percent meter the present invention provides a kind of coconut oil micro-capsule fatty powder

Selected sow starts to test when attacking tire within 86 days, terminates after breeding to the wean of all sows.Test group (B group) and control
Group (A group) feeds corresponding daily ration respectively, attacks every sow of tire phase all by 3.5kg/d Diet, single column position limiting fence raising.
The just before giving birth preceding 7d of sow is uniformly transferred to childbirth house, every sow separated raising after the disinfection of pig body, and Farrowing same day unification is fed
0.5kg feeds 2kg in second day, increases 0.5kg on the basis of the previous day daily later, is freely eaten until 26 within puerperal 7th day
Age in days wean, presses every sow 3.5kg/d Diet after wean.In second day (after colostrum) of giving a birth, between daily ration processing group
Adjustment suckling pig number (every sow lactation 11, litter weight is close as far as possible) is to promote intensity stimulation of uniformly sucking the breast, before wean
Every nest piglet is not providing feed supplement.
Immune disinfectant program is carried out by pig farm conventional method, and swinery health status is checked daily.
Record data:
1) weight when record sow starts test, after childbirth, when weaning；
2) daily sow feed intake is recorded；
3) with P2 point back-fat thickness when wean when recording Farrowing: last rib cage is P2 point at dorsal line 5-6cm,
By back fat analyzer；
4) litter size, number born alive, strong young number (weight > 1kg), delivery time, piglet Birth weight；
5) survival rate when weight, weaned piglet when weaned piglet；
6) 7 days Oestrus rates after 5 days and wean after sow wean.
Experiment effect data obtained are shown in Table 2.
2. test result of table
Note: ± indicate standard deviation；Alphabetical a, b, alphabetical difference person's significant difference (p < 0.05) of going together.
From upper table data it is found that the Farrowing time slightly shortens, the production process piglet death rate is reduced, nursing period feeding
Amount has small size raising, and milk is more sufficient, and suckling pig average daily gain is improved, and sow lactation weightlessness is reduced, wean to heat
Time shortens, and produces parity per year and increases, and sow utilization rate improves, and year provides piglet number and improves, and overall economic efficiency improves.
