Description
Technical field
The present invention relates to a kind of composite premixed feed for pigs that improves the anti-heat stress ability, belong to field of fodder.
Background technology
Heat stress typically refers under the influence of environment temperature above the thermophilic district upper limit (being higher than 23 ℃ like boar, big pig) of animal, because of heat production in the body and unbalance a series of physiology that cause of heat radiation and the negative performance on the ethological function.The place that the middle part of China's length and breadth of land (Hubei, Henan, Hunan, Jiangxi, Anhui) and their edges close on; All be in Northern Hemisphere monsoon climate zone; Annual have approximately reach five months daily mean temperatures and surpass 22 ℃ season, have to reach three months daily mean temperatures and surpass 28 ℃ time.Along with the trend of global warming, this continuous high temperature weather prolongs, and the zone is also enlarging.
Megathermal climate, particularly continuous high temperature high humidity weather are produced to live pig and are brought quite serious consequence.Heat stress shows as to the influence of boar reproductive capacity that semen volume reduces, abnormal spermium increases, sperm motility descends; Influence to fertility of sow shows as not obvious or out of heat, the ovulation minimizing of oestrusing.Heat stress can influence Farrowing, causes that bradytoia, stillborn foetus increase, retention of afterbirth, PNI probability rise; Also cause simultaneously lacking postpartum breast or agalasisa, constipation, uterine involution postponement, post-partum estrus postponement, return phenomenons such as feelings increase; Heat stress also can cause miscarriage.Heat stress makes pig reduce the activity of hypophysis and neuroendocrine system by the light of nature, and gastrointestinal peristalsis is slowed down, and digestive juice secretions such as gastric juice reduce, and appetite reduces, thereby decreased growth, and the material anharmonic ratio rises.Under the heat stress influence, pig body immunity degradation, the incidence of disease of infectious diseases raises.
Summary of the invention
In order to alleviate and to eliminate the influence that heat stress is produced live pig, the present invention starts with from the nutrition angle, and a kind of composite premixed feed for pigs that improves the anti-heat stress ability is provided.
The technical scheme that the present invention adopted is:
A kind of composite premixed feed for pigs that improves the anti-heat stress ability contains in per 1 kilogram of premix: 98.5% threonine 40g, 98.5% coated vitamin C 40g, composite B vitamin 80g, probiotic 80g, complex enzyme formulation 40g, 1.23% chromium picolinate 12g, sodium bicarbonate (food-grade) 500g, anti-oxidant 0.3g, thick litter shell powder 100g, medical stone 107.7g.
Said composite B vitamin is one or more in vitamin B6, cobalamin, nicotinic acid, folic acid and the biotin.
Said probiotic is a bacillus subtilis.
Said complex enzyme formulation is one or more in zytase, cellulase, amylase and the dextranase.
Said anti-oxidant is an ethoxyquinoline.
But threonine balanced ration amino acid promotes the synthetic and deposition of protein; It has certain regulating action to feed intake, and feed intake and daily gain increase with the rising of threonine level; Threonine lacks can suppress immunoglobulin (Ig) and lymphocytic generation, thereby influences immunologic function; Metabolism has tangible influence to body fat in the animal daily ration, to add threonine, and it can promote the synthetic and fatty acid oxidation of phosphatide; Threonine plays an important role in safeguarding particularly newborn intestine of young pigs health of pig and intestinal mucosa function, can reduce the grice diarrhoea rate.
The function that vitamin C is alleviated heat stress has the following aspects: 1, the output of corticosteroid increases during heat stress, and the synthetic vitamin C that needs of corticosteroid hormone.2, high temperature stress the time, need to consume significant amount of energy through the heat radiation of breathing, replenishing vitamins C help anti-stress.Because vitamin C is that synthetic carnitine is necessary, and carnitine is to supply requisite a kind of metabolic factor to muscular energy.3, in the heat stress process, vitamin C helps to keep higher feed intake, thereby guarantees the adverse effect of enough nutrition supply opposing heat stresses.
Enzyme preparation is applied in the animal feed; The degradable plant cell membrane, eliminate ANFs, reduce the chyme viscosity, change archenteric flora, improve nutrient digestibility, influence endogenous digestive enzyme activity, thereby improve efficiency of feed utilization, improve breeding performonce fo animals.
Probiotic is meant under the animal microecology theoretical direction and adopts known beneficial microbe, is used for biologic product or the active bacteria formulation that animal produces through what special process such as cultivation, fermentation, drying were processed.It has the growth of animal of promotion, suppresses the pathogen breeding, improves the interior microbial balance of enteron aisle to keep functions such as intestinal health, control disease of digestive tract and enhance immune function, also has nutritional supplementation and the effect that improves efficiency of feed utilization simultaneously.
Chromium is a kind of trace element, and it assists insulin to participate in the carbohydrate metabolism of body through forming organic chelate-glucose tolerance factor with niacin, glutamic acid and glycine etc.; Its scalable protein metabolism promotes protein synthetic thereby promote amino acid to get into cell, helps the deposition of muscle and other histones; Chromium also plays an important role to lipid metabolism, can reduce cholesterol and triglycerides in the fattening pig serum, reduces abdomen fat rate, improves carcass quality, improves reproductive capability.The various Blood cortisol concentration that stress make raise, and immune system is produced inhibitory action, and chromium picolinate is participated in immunoregulation in the body, but the ability of enhancing body immune response, thereby strengthen body to stress resistance.
Sodium acid carbonate is a kind of common additive agent electrolyte and acid-base modifier, adds the cushion effect that sodium acid carbonate helps enhancing body in the daily ration, improves the storage of blood pH and alkali, helps internal system operate as normal under stress situation, improves the anti-heat stress ability.
In the feed some composition easy because of with airborne oxygen, feed in the contacting oxidation deterioration, lost efficacy or become sour of peroxide and unrighted acid etc.; Make nutritive value decline, the palatability variation of feed; The peroxide of its formation simultaneously also has toxic action to animal, and is particularly more obvious at high temperature season.An amount of anti-oxidant that adds can effectively postpone or prevent the effect of this type oxidative rancidity, particularly under the environmental condition of higher season of temperature or other easy oxidations.
Medical stone is a kind of through alteration, weathering or half weathering; Intermediate acidity magmatic rock mineral matter with spot shape or porphyritic-like texture; Can produce a large amount of acid ions that has negative electrical charge when water-soluble; This structures shape it strong selection adsorptivity is arranged, can reduce in the animal body some pathogen and harmful heavy metal etc. to the infringement of animal body.
Beneficial effect of the present invention is: premix of the present invention can improve resistance and the feed intake of pig under hot climate; The balance gut flora is also kept intestinal health; Assist to strengthen pig digesting and assimilating to food; Thereby improve the production performance of pig, can avoid also can adjusting the acid-base balance of fluid of inside and outside cell body environment because of heat stress causes that sow is out of heat, the situation of embryonic death and miscarriage.
