Description

A kind of feed alleviating beef cattle heat stress

Technical field

The invention provides a kind of cattle feed, beef cattle heat stress problem can be alleviated, belong to field of animal feed.

Background technology

Beef contains rich in protein, and amino acid composition geometric ratio pork needs closer to human body, can improve body resistance against diseases, to grow and Post operation, aftercare people to lose blood and suitable especially in repair tissue etc. supplementing.Severe winter eats beef, has warm stomach effect, is help in severe winter good merchantable brand.During the last ten years, China's economy obtains develop rapidly to reform and opening-up three, and maximum embodiment is that people's living standard is improved.Therefore the consumption demand of people to beef increases year by year, and beef price rises for continuous 13 years.China has been the large Beef production in third place in the world and consumption big country, is only second to the U.S. and Brazil.But China per capita beef consumption figure has a long way to go compared with developed countries, to China in 2012 per capita beef year consumption figure be 4.1 kilograms, not only well below the U.S. (44.1 kilograms/people), and the half of too late world average level, market development space is huge.

Have benefited from smooth vast grassland, the north, the north is the traditional plant-eating animal advantage producing region of China always.But due to long-term overgraze, natural meadow herding bearing capacity, considerably beyond warning line, causes grass-land deterioration, desertification.And boreal climate severe cold, in a herbage long season, stopping for three seasons, is the bottleneck of grassland animal husbandry.And southern climates is warm moist, be very applicable to pasture growing, therefore south is the new hope of grassland agriculture development.Therefore, for grassland agriculture, the viewpoint that expert proposes " northern breeding, south is fattened ".Make full use of the sufficient Niu Yuan in the north exactly and breed experience, growing and fattening is carried out in south herding cub being forwarded to forage grass abundance.

In recent years, domestic beef demand rose year by year, saw lucrative, and some capitals have poured in steer ration industry.The particularly southern provinces and cities such as Guangxi, Jiangxi, Guizhou, Yunnan, Hainan, Chongqing, Hunan, big and small steer ration field is set up like the mushrooms after rain.Because the beef breed build in the north is large, fast growth, the price of deed are high, the kind overwhelming majority of southern steer ration field cultivation from Jilin, Inner Mongol, the northern province such as Liaoning introduce.The ox cold resistance of north kind is strong, but heat-resisting difference, particularly at the First Year of south cultivation, occur various stress, particularly heat stress, causes beef cattle in poor growth in summer, even dead, cause heavy losses to raiser, a lot of plant all loses money operation.For reply beef cattle heat stress, fan, spraying exhausting system have been installed by some plants, and even install an air-conditioner to cowshed, aquaculture cost is very high.Report shows according to the study, and so long as not direct sunlight with it the ox, ox can be resistance to 40 DEG C, the even high temperature of 42 DEG C.Therefore, solve the heat stress problem of ox, not only set about from improving breeding environment, feed formula is also very crucial.

Alleviate beef cattle heat stress problem, most of document is set about from additives such as giving Niu Tianjia multivitamin, trace element, potassium chloride, sodium acid carbonate, and some documents give and add heat-clearing Chinese herbal medicine as peppermint, wrinkled giant hyssop, dried orange peel etc. in feed.These methods, because cost is high, are difficult to promote the use of.

Summary of the invention

The invention provides a kind of feed can alleviating beef cattle heat stress, feed cost of the present invention is low, ensures that beef cattle is in the normal feed intake of hot summer and certain speed of growth, effectively solves the problem that beef cattle is fattened summer, reduces cultivation risk, provide culture benefit.

Feed of the present invention, is made up of the raw material of following percentage by weight:

Corn 30 ~ 40%; Wheat bran 30 ~ 40%; Dregs of beans 16%; Callicarpa nudiflora 5%; Mung bean 2 ~ 5%; Chinese mesona herb 2 ~ 4%; Potassium chloride 0.5%; Salt 0.5%; Sodium acid carbonate 1%; Magnesia 0.5%; Vitamine C sodium 1.5%.

Described corn, the dry son of the maturation for grass Zea mays is real.Corn is the basal feed of animal, and effective energy value is high, and metabolizable energy is 14.06MJ/kg, is the soprano in the real feed of paddy, is known as the king of feed.Corn good palatability, energy is high, generally a large amount of in the fine fodder of ox, but due to beef cattle search for food in a large number after quantity of heat production increase, be alleviate beef cattle heat stress, in the Concentrate formula of summertime beef cattle, should content be reduced.

Described wheat bran, is commonly called as wheat bran, is the accessory substance obtained during wheat processing flour.Wheat bran good palatability, the salt containing laxative qualits, the effect contributing to gastrointestinal peristalsis and relax bowel.The metabolizable energy of wheat bran is 6.82MJ/kg, and metabolizable energy is lower, can alleviate the heat stress phenomenon of ox.

Described mung bean, the dry son of the maturation for legume Vigna radiata (Linn.) Wilczek. is real.Mung bean has detumescence ventilation, and clearing heat and detoxicating effect, can be used for prevention and therapy heatstroke.

Described Chinese mesona herb is the dry herb for labiate Mesona chinensis Benth. (have another name called: Mesona chinensis Benth, celestial being is frozen, celestial grass).Chinese mesona herb is one of the main component of cold tea king Lao Ji of getting angry, and has effect that is clearing heat and detoxicating, clearing away summerheat.

Described callicarpa nudiflora be the dry aerial parts of Verenaceae Callicarpa plant Callicarpa nudiflora Hook.et Arn. or dry complete stool.Callicarpa nudiflora there is antiphlogistic antibacterial, hemostasis, detoxify, protect the liver antipyretic effect.Because mosquito, fly bite the various courses of infection and inflammation that cause during effectively can treating beef cattle summer, also can treat beef cattle stomach inflammation and hemorrhage of digestive tract, thus strengthen beef cattle physique, improve the harm of heat stress to ox.

Described dregs of beans is a kind of byproduct obtained after soybean extracting bean oil, and protein content is greater than 40%, is one of main protein feeds of animal.

Potassium ion is the mineral matter element that animal body intensive amount accounts for the 3rd, plays very important effect at animal body.In the summer of sweltering heat, the increase of animal amount of sweat, amount of drinking water and urine volume increase, and potassium content in blood is declined, thus makes animal easily occur heat stress.So in the summer of sweltering heat, will supplement potassium element to animal, the present invention adopts the form of adding potassium chloride to alleviate the heat stress of beef cattle.

Bibliographical information, vitamin C has the effect for the treatment of beef cattle heat stress.But the easy oxidation deterioration of vitamin C, particularly in moist hot summer, ascorbic preservation bothers very much.Vitamine C sodium is ascorbic sodium salt, and after being absorbed by body, the effect of generation is equal to vitamin C, but its stability is better than vitamin C.Therefore the present invention adopts vitamine C sodium to be prevention, the additive alleviating beef cattle heat stress.

Sodium acid carbonate and magnesia are alkalescent material, have cushioning effect to beef cattle rumen ph environment.Meanwhile, magnesium elements has the effect suppressing N&M excitement and maintain heart normal function, and the activator of the multiple enzyme such as magnesium elements or pyrophosphatase, cholinesterase, adenosinetriphosphataes, peptase.Therefore adding magnesia can regulate beef cattle metabolic normally in summer, and prevention is gentle separates heat stress.Described salt, chemistry sodium chloride by name, supplements sodium and chlorine element to animal, can improve the feed intake of beef cattle and improve the digestibility of roughage.

The good effect that the present invention produces:

1. reduce the corn content that quantity of heat production is high in feed formula, adopt the low wheat bran of effective energy value can either ensure the normal weightening finish in beef cattle summer, prevent again and alleviate beef cattle to occur heat stress.

2. the wheat bran in feed formula has and stomach invigorating the spleen, the effect that contributes to gastrointestinal peristalsis and relax bowel, can increase beef cattle amount of drinking water and defecation, has positive role to opposing heat stress.

3. callicarpa nudiflora in feed formula is Guangxi Common Chinese Herbs, has antiviral, anti-inflammatory, hemostasis, detoxifies and protect the liver antipyretic effect.Because mosquito, fly bite the various courses of infection and inflammation that cause during effectively can treating beef cattle summer, also can treat beef cattle stomach inflammation and hemorrhage of digestive tract, thus strengthen beef cattle physique, prevention and therapy beef cattle heat stress.

4. the potassium chloride in feed addictive can prevention and therapy heat stress; Sodium acid carbonate and magnesia play cushioning effect to rumen ph environment, and ensure the stable of ox digestive system, magnesium elements can regulate beef cattle at the eubolism of hot summer simultaneously, the generation of prevention heat stress.Finally, adopt vitamine C sodium to replace the vitamin C of easy oxidation deterioration, the validity of the feed of guarantee, strengthen the effect of the prevention and therapy heat stress of feed.
