Abstract
The present invention relates to an anti-heat stress feed additive for pregnant sows, wherein a Chinese herb additive, sodium bicarbonate, citric acid, lysine, aminobutyric acid, fructooligosaccharide and wheat bran are used to prepare the anti-heat stress feed additive. With the anti-heat stress feed additive of the present invention, the problems of heat stress and constipation of pregnant sows can be effectively alleviated, the sow feed intake can be increased, the embryonic death caused by heat stress can be prevented, and the litter size is increased.
Description
Technical field
The present invention relates to animal feed additive field, be specifically related to a kind of in-pig anti-heat stress feed additive.
Background technology
The sow gestation phase terminates to giving a birth from ovum fertilization, average 114 days (111-117 days).Growing of fetus relies on parent completely, and the feeding and management of in-pig is directly connected to growing of embryo, litter size, birth weight, piglet survival ratio, daily gain, the rutting in milking capacity and next cycle.Good feeding and management is carried out to gestational period sow, sow can be made to increase in pregnancy duration body weight, guarantee embryo growth and development is good, reduce the death of embryo to greatest extent, produce to lift one's head and count the piglet many, birth weight is large, vitality is strong, the body condition of sow unsoundness in postpartum and good milk performance, thus improve Swine Production level.Pig belongs to homeothermal animal, and sweat gland is undeveloped, and in body, heat energy distributes comparatively slow, and when the heat production of pig is greater than heat radiation, body temperature raises, and easily physiological responses to heat stress occurs.Research shows, before and after insemination of sows, 1-3 week is responsive especially to high temperature, be subjected to the sow of heat stress in rear 1-3 week with breeding before and after breeding, its conception rate obviously reduces, and occur that embryo absorbs and death in early days, thus litter size obviously reduces, latter half of gestation is the critical period that fetal weight increases, high temperature can affect the normal development of fetus, and the in-pig later stage stands heat stress, has certain influence to sow to the passive immunity of fetus.In addition, summer high temperature also can cause sow while causing sow heat stress water and salt metabolic disturbance, gastrointestinal peristalsis is slowed down, thus cause prevention of sow constipation, the harm that constipation brings to sow is mainly manifested in: Farrowing increased periods is even had difficult labour, sow is by the impact of heat stress, the adrenaline of body hypercrinism, uterine vascular is caused to shrink, thus the oxytocins of arrival uterine smooth muscle is reduced, uterus muscle can not get enough oxygen, causes uterotonic frequency and intensity to reduce, causes delivery time to extend.Produce weak stillborn foetus number to increase, sow produces strong young number and declines, and young rate of living reduces; Postpartum, appetite reduced, dysgalactia, milk production minimizing etc.
At present the prophylactico-therapeutic measures of in-pig heat stress is comprised and take measures of heat control, nice and cool environment is provided to sow, increase the fat content in feed, vitamin C, vitamin E, sodium bicarbonate, trace element chromium and electrolyte etc. are added in feed, but, existing measure is all partial rcsponse, does not have reasonable effect.In the urgent need to developing the anti-heat stress feed additive of a kind of in-pig, providing technical support for alleviating in-pig heat stress, making the level of production on pig farm not be subject to serious impact under the environment of sweltering heat, obtaining maximum value.
Summary of the invention
For problems such as the heat stress existed in existing in-pig cultivation and constipation, the present invention aims to provide a kind of in-pig anti-heat stress feed additive.
For solving above technical problem, the present invention adopts following technological means:
A kind of in-pig anti-heat stress feed additive, is made up of the raw material of following weight portion: Chinese herb feed additive 45-55 part, sodium acid carbonate 2-9 part, citric acid 3-6 part, lysine 3-5 part, g-aminobutyric acid 4-8 part, FOS 7-11 part and wheat bran 20-25 part are made;
