Abstract
The present invention relates to a kind of feed addictive for alleviating heat stress of cow in summer, belong to animal feed additive technical field.The additive includes powdered oil, vitamin C, Tea Polyphenols, honeysuckle, cordate houttuynia, maltodextrin, the additive is added in cow concentrated feed according to mass percent for 5%~12% additive capacity, it is well mixed, whole day feeding is carried out to milk cow in summer.The present invention improves milk cow to altithermal tolerance, strengthen oxidation resistance, effectively alleviate the heat stress of milk cow, solve the problems, such as that China causes dry matter intake decline, postpartum negative energy balance in summer high temperature season cow heat stress, the output of milk and dairy products quality of heat stress milk cow are improved, is had broad application prospects.
Description
(1) technical field
The present invention relates to a kind of feed addictive for alleviating cow heat stress and its application, belong to animal feed additive skill
Art field.
(2) background technology
Cow heat stress is that during the broiling summer, milk cow is by the excessive temperature stimulation more than Thermoregulation ability itself
When, act on hypo_pit_adr cortex, the nonspecific defense reaction of caused body and specific disorder
A series of summation of biochemical reactions inside.Domestic dairy bread is generally Chinese holstein cattle, and it is noteworthy characterized by fearness
Heat is cold-resistant, and extremely sensitive to summer high temperature, main cause is that its build is larger, and the surface area of per weight is small, body surface hair and
The good heat insulating of body tissue, the undeveloped heat dissipation capacity for causing skin to evaporate of sweat gland is few.Heat stress can cause milk cow anorexia,
Feed intake declines, and significantly reduces milk cow dry, crude protein, crude fat, NDF, ADF and Ca and P digestibility.During heat stress
Milk cow produces to reduce heat, it will usually reduce the feed intake of roughage；Meanwhile, accelerated breathing, body protein, fat and
The catabolism enhancing of carbohydrate, anabolism reduction；And under the conditions of heat stress, the percent of pass of food is slack-off in stomach, can
Reflectivity causes rumen activity and convergent force to decline, and the Ruminant behavior of milk cow is suppressed by a certain degree of, reduces milk cow
Ruminate efficiency, Rumen Internal Environment changes, pH value rise, ammonia-nitrogen content and general volatile fatty acid concentration reduction, body
Negative balance state in energy and nitrogen metabolism, the blood flow volume that milk cow flows to breast is reduced, and ultimately results in the body nutrition of milk cow
Insufficiency of intake, output of milk reduction.
Heat stress has had a strong impact on the reproductive capability of bull, under normal circumstances, and scrotum has certain thermal conditioning ability, testis
Ball can keep 3~7 DEG C lower than body temperature of preference temperature.The weather of summer high temperature, high humidity, can cause bull radiating not smooth, body temperature
Rise, beyond the regulating power of testis itself, causes the gentle testis temperature of scrotum skin to rise, causes germinal epithelium to be denatured, make
The maturation and storage, gonadal hormone secretion amount and its composition of sperm change, and cause summer sterility bull to increase.Heat stress
It is the principal element for causing torridity summer cow reproduction performance to reduce.Cause follicle-stimulating hormone and luteotropin to be secreted to decline, progesterone
With estrogen level reduction, shorten estrus time, sexual cycle extension, ovulate slow, folliculus depauperation and ovarian follicle form
It is abnormal.Under the conditions of heat stress, the dark heat of cow increases, and is unfavorable for development of fertilized ova and attached plant, rate of embryonic death increase, fertilization
Rate, pregnancy rate decline, cause milk cow it is infertile, miscarriage.
In summary, cow heat stress causes the principal element of milk cattle cultivating decline in benefits as summer, explores effective
Control heat stress technical measures be development of dairy industry in the urgent need to.
(3) content of the invention
It is an object of the invention to provide a kind of feed addictive for alleviating heat stress of cow in summer, it can effectively prevent and treat gentle
Cow heat stress is solved, milk cow appetite and feed intake is improved, improves the production performance of milk cow under heat stress state.
The technical solution adopted by the present invention is：
A kind of feed addictive for alleviating cow heat stress, is mixed by the following component of mass content：
Surplus is maltodextrin.
Powdered oil is also known as cream, fatty powder, is to refine hydrogenated vegetable oil and numerous food auxiliary material as raw material, through adjusting
Match somebody with somebody, emulsify, sterilizing, being spray-dried and form.
By above-mentioned recipe calculation and each component raw material dosage (wherein honeysuckle and cordate houttuynia are dry product powder) is weighed, with life
The feed addictive of the well mixed alleviation cow heat stress that can be obtained by the present invention of the mixer of production premix.
It is preferred that, the feed addictive quality composition is as follows：
Surplus is maltodextrin.
It is more highly preferred to, the feed addictive quality composition is as follows：
Surplus is maltodextrin (48.3%).
The beneficial effect of the feed addictive of the alleviation cow heat stress of the present invention is mainly reflected in：
(1) physiological responses to heat stress of milk cow is significantly alleviated, the average daily output of milk improves 9.1%, and the protein ratio of Dairy Cows In Summer is carried
High by 4.3%, butterfat percnetage improves 2.6%.
(2) daily ingestion amount of Dairy Cows In Summer is improved, the digestibility of feed is improved.
(3) oxidation resistance and resistance against diseases of milk cow are improved, improves the physiological status under the conditions of cow heat stress, reduction
The mastitis incidence of disease, improves cow reproduction rate.
(4) easily, preparation technology is simple, and easy to use, financial cost is relatively low, is conducive to promoting in production for material source
Utilize.
(4) embodiment
With reference to specific embodiment, the present invention is described further, but protection scope of the present invention is not limited in
This：
Embodiment 1：Prepare the feed addictive for alleviating cow heat stress
Accurately weigh material powder grease (Yang Lin greases group of Heilongjiang Province) 25kg (50%), vitamin C 75g
(0.15%), Tea Polyphenols 175g (0.35%), honeysuckle 350g (0.7%), cordate houttuynia 250g (0.5%), are mended with maltodextrin
Enough to 50kg.Above-mentioned raw materials are stirred with portable agitato, added the feed of obtained alleviation cow heat stress when using
Plus agent is mixed into cow concentrate (Chengdu Wei Laite Science and Technology Ltd.s) according to 8% (w/w) ratio, for feeding cow.
Embodiment 2：Alleviating the feed addictive of cow heat stress is used to prevent and treat cow heat stress
Choose that body weight, age, parity, the output of milk be close and holstein cow 50 without mammitis, in heat stress condition
Lower to be tested, temperature range is 32~40 DEG C, and relative humidity was 72~79% (mid-Julys~mid-August, Jinhua, Zhejiang
Area).50 cow heads are divided into two groups, and one group is control group, the conventional daily ration of feeding；Another group is test group, and feeding contains the present invention
The daily ration of feed addictive.After long run test 15 days, the daily ingestion amount and daily yielding of 3 days each group milk cows of record calculate each group
The average daily milk production of milk cow.The part milk sample of each group collection is used for the measure of milk constituents, while determining milk cow with CMT methods
Recessive mastitis incidence.Result of the test shows：Compared with control group, test group daily ingestion amount improves 12.4%, the output of milk
9.1% is improved, protein ratio improves 4.3%, and butterfat percnetage improves 2.6%, mammitis incidence of disease reduction by 13.7%.Above-mentioned experiment knot
Fruit shows, the feed addictive of the present invention is added in milk cow forage, the output of milk of heat stress milk cow can be significantly improved, and improves
The protein ratio and butterfat percnetage of milk, reduce the mastitis for milk cows incidence of disease triggered by heat stress, prepare simple, price is relatively low,
With wide market promotion prospect.
