Description
Technical field
The present invention relates to a kind of method improving animal reproduction rate, particularly a kind of method improving the reproduction rate of yak.
Background technology
Yak is with China Qinghai-Tibet Platean for the specialty economies animal of area of origin and the view ox kind of the roof of the world, is the genetic resources of China's preciousness.The high and cold grassland Forage Germplasm Resources of billions of mu, China can only rely on yak, Zang Yanglai is converted into animal product, the production, life, culture, religion etc. of Qinghai-Tibet Platean Alpine-arctic Pastoral herdsman 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 increasing yak quantity, improve yak quality.In natural breed cows, reproduction rate is generally 60% ~ 75%, and reproductive survival rate is 45% ~ 75%.Yak cow 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, connect productive rate lower than 55%.The Yak cow pregnancy duration average 255d (250 ~ 260d), possesses the primary condition of producing for 1 year 1.But yak is all the year round to herd, and extensive management, significantly limit 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 improving yak reproduction rate is provided, the inventive method utilizes yak reproductive physiology feature, the seasonal production law of feature and Alpine-arctic Pastoral is herded in conjunction with yak in Qinghai-tibet, realize yak to produce for 1 year 1, fully excavate the reproductive potential of yak, improve the reproductive efficiency of yak, not only be conducive to adjustment yak and store group structure, and in being convenient to yak seed selection and producing, organization and administration and drove have enough to meet the need.
For achieving the above object, the present invention is by the following technical solutions:
Improve a method for yak reproduction rate, comprising: breeding time point is that 7 ~ September, calving time point are 4 ~ May of next year, weaning time point is calving 7 ~ August then then; Described breeding, between calving and weaning time control point implement breed supplementary measures; 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 carried out on Qinghai-Tibet Platean.
In a preferred embodiment of the present invention, described weaning time is a point puerperium 90 ~ 100d, fatten to deliver calf for sale and take to herd+supplementary feeding intensity fattens measure, provides sufficient fine fodder and green grass; 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 described breeding public 4 ~ 9 years old yak age, body weight is not less than 320kg; At 4 ~ 10 years old Yak cow 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 when herding, and returns and herds 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 number ratio is 1:5 ~ 20; The public Yak Growth of described kind physically well develops, health, has Seed practical value.
In a preferred embodiment of the present invention, described basis female yak nutrition regulation takes supplementary feeding measure: breeding season average daily supplementary feeding fine fodder 0.5kg, latter half of gestation average daily supplementary feeding fine fodder 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: train the material that pastures after birth 10d, and after birth 30d, every day mends and feeds fine fodder 0.4 ~ 0.8kg.
Beneficial effect of the present invention:
The yak breeding mode of the present invention's tissue, fully can excavate the breeding potential of Reproductive Female yak, improves the reproductive efficiency of yak, is conducive to adjustment yak composition of livestock herds, increases yak quantity, improve production of yak performance.System was produced or produced for 3 years 2 to its production efficiency than 2 years 1 increase by 30% ~ 40%, and reproductive survival rate improves 10% ~ 15%.Within this 1 year 1, produce the method improving yak reproduction efficiency, be suitable for and use in yak seed selection with production.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention flow chart.
In figure: 1, rutting time controling point; 2, childbirth calving time controling 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, next production cycle is entered.Wherein rutting time controling point 1, childbirth calving time controling point 2 form 1 year 1 with calf weaning time control point 3 and produce; 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 ensures that calf grows and key period of calf seed selection; Yak supplementary feeding time-critical point 6 is that stock bull keeps production fine quality seminal fluid, basic cow recovers body condition and keeps breeding the physiology normal key period; Start post-partum estrus through 5 ~ 10d Yak cow after wean, enter next production cycle 7.
