Abstract
The invention relates to a method for improving the reproductive rate of yaks. The method for improving the reproductive rate of yaks includes the following steps that a hybridization time control point, a calving time control point and an ablactation time control point are set; breeding supporting measures are implemented among the hybridization time control point, the calving time control point and the ablactation time control point; the hybridization time control point ranges from 7-9 months, the calving time control point ranges from 4-5 months and the ablactation time control point ranges from 7-8 months. The breeding supporting measures include that feed is supplemented for hybridization male yaks, nutrition of basic female yaks is regulated and controlled and ablactation calves are bred. The technology and the method are comprehensive, convenient to operate, capable of making full use of reproduction potentials of female yaks, capable of achieving the purpose that reproduction of yaks can be performed once a year, improving the number of the yaks and effectively improving the reproduction efficiency of the yaks and suitable for being used in breeding and reproduction of yaks.
Description
Technical field
The present invention relates to a kind of method that improves animal reproduction rate, particularly a kind of method that improves the reproduction rate of yak.
Background technology
Yak Shi Yi China Qinghai-Tibet Platean is the genetic resources of the specialty economies animal of area of origin and view Niu Zhong，Shi China preciousness of the roof of the world.The high and cold grassland Forage Germplasm Resources that China is billions of mu can only rely on yak, Zang Yanglai to be converted into animal product, Qinghai-Tibet Platean Alpine-arctic Pastoral herdsman's production, life, culture, religion etc. have close relationship with yak, and yak has irreplaceable ecology, society, economic status in Distribution Area.
Yak reproduction is the basic link in production of yak, is the prerequisite that increases yak quantity, improves yak quality.In natural breed cows, reproduction rate is generally 60%～75%, and reproductive survival rate is 45%～75%.Female yak puberty,, just joining the age was 2.5～3.5 years old generally at 1.5～2.5 years old.Yak reproduction power is low, within general 2 years 1, produces or produces for 3 years 2, connects productive rate lower than 55%.Female average 255d of pregnant yak (250～260d), possesses the primary condition of producing for 1 year 1.But yak be take all the year round and herds as main, extensive management, has greatly limited the production efficiency of yak.Therefore, develop and a kind ofly improve yak reproduction rate, realize the method that yak produces for 1 year 1 and seem very important.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, a kind of method that improves yak reproduction rate is provided, the inventive method is utilized yak reproductive physiology feature, in conjunction with yak in Qinghai-tibet, herd the seasonal production law of feature and Alpine-arctic Pastoral, realize yak and produce for 1 year 1, fully excavate the reproductive potential of yak, improve the reproductive efficiency of yak, not only be conducive to adjust yak and hold group structure, and organization and administration and drove turnover in being convenient to yak seed selection and producing.
For achieving the above object, the present invention is by the following technical solutions:
A method that improves yak reproduction rate, comprising: breeding time point is that 7～September, calving time point are that 4～May of next year, weaning time point are calving 7～Augusts then then; Between described breeding, calving and weaning time control point, implement to breed supplementary measures; The described supplementary measures of breeding comprise breeding male and female yak supplementary feeding, basic cow nutrition regulation and Weaned calves cultivation; Preferably, described method is to carry out on Qinghai-Tibet Platean.
In a preferred embodiment of the present invention, described weaning time is a minute puerperium 90～100d, fatten to deliver calf for sale and take to herd+supplementary feeding intensity fattens measure, sufficient fine fodder and green grass is provided; The calf of selecting and remain is carried out and lacks phase wean measure, lacks phase weaning time interval 5～10d, day supplementary feeding fine fodder 0.7～1.0kg.
In a preferred embodiment of the present invention, at public 4～9 years old yak age of described breeding, body weight is not less than 320kg; At female 4～10 years old yak age, body weight is not less than 210kg.
In a preferred embodiment of the present invention, described stock bull supplementary feeding scheme is: day supplementary feeding mixed concentrate 1.5～2.0kg, free choice feeding while herding, returns and herd rear supplementary feeding nutrition lap brick and high-quality green grass or hay.
In a preferred embodiment of the present invention, described breeding male and female yak quantity is than being 1:5～20; The public Yak Growth of described kind physically well develops, health, has kind by value.
In a preferred embodiment of the present invention, described basis female yak nutrition regulation is taked supplementary feeding measure: breeding season average daily supplementary feeding fine fodder 0.5kg, the average daily supplementary feeding fine fodder of latter half of gestation 1.0kg, lactation average daily supplementary feeding fine fodder 1.0～1.5kg, simultaneously supplementary feeding nutrition lap brick and high-quality green hay.
In a preferred embodiment of the present invention, described calf breeding measure is: after birth 10d, train the material that pastures, after birth 30d, mend and feed fine fodder 0.4～0.8kg every day.
Beneficial effect of the present invention:
The yak breeding mode of the present invention's tissue, can fully excavate the breeding potential of Reproductive Female yak, improves the reproductive efficiency of yak, is conducive to adjust yak composition of livestock herds, increases yak quantity, improves production of yak performance.Its production efficiency was produced than 2 years 1 or 3 years 2 product systems increase by 30%～40%, and reproductive survival rate improves 10%～15%.Within this 1 year 1, produce the method that improves yak reproduction efficiency, be suitable in yak seed selection and in producing and use.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention flow chart.
In figure: 1, rutting time control point; 2, childbirth calving time control point; 3, calf weaning time control point; 4, cow nutrition regulation time-critical point; 5, calf breeding time-critical point; 6, yak supplementary feeding time-critical point; 7, enter next production cycle.Wherein rutting time control point 1, childbirth calving time control point 2 form 1 year 1 product with calf weaning time control point 3; Yak nutrition regulation time-critical point 4 is key periods that pregnant cow nutrition supply and normal fetal are grown; Calf breeding time-critical point 5 is the key periods that guarantee that calf grows with calf seed selection; Yak supplementary feeding time-critical point 6 is that stock bull keeps production fine quality seminal fluid, basic cow to recover body condition and keeps breeding the normal key period of physiology; Wean starts post-partum estrus by the female yak of 5～10d, enters next production cycle 7.
