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 hiding sheep.
Background technology
Hiding sheep and be mainly distributed in Tibetan Plateau and its adjacent regions, is one of Qinghai-Tibet distinctive Animal Genetic Resource.Owing to affecting by Qinghai-Tibet natural conditions, eco environment facto, define the ecological physiology characteristic of its uniqueness.Hiding sheep is the basic production means of livelihood of Alpine-arctic Pastoral, mainly provides nutritious, the mutton product of green non-pollution, the raw material of industry such as Yi Jimao, skin.
Hide sheep breeding be hide sheep produce in basic link, be increase to hide sheep quantity, improve the prerequisite of hiding sheep quality.Hide about the 150 days sheep ewe pregnancy duration, annual lambing 1 time, every tire 1 lamb, reproductive survival rate 50% ~ 70%.General ewe started to oestrus at 1.5 years old, breeding utilization periods 5 ~ 6 years.But hide sheep all the year round to herd, extensive management, significantly limit the production efficiency of hiding sheep.Therefore, develop a kind of raising to hide sheep reproduction rate, realize hiding the method that sheep produces for 2 years 3 and seem very important.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, there is provided a kind of and improve the method for hiding sheep reproduction rate, the inventive method utilize hide sheep ewe maternal instinct good, educate the strong feature of lamb ability, the seasonal production law of feature and Alpine-arctic Pastoral is herded in conjunction with Tibetan plateau sheep, realize hiding sheep to produce for 2 years 3, fully excavate the reproductive potential hiding sheep ewe, improve the reproductive efficiency hiding sheep, not only be conducive to adjustment and hide sheep composition of livestock herds, and in being convenient to Tibetan sheep 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 of hiding sheep reproduction rate, comprising: carry out at 3 breeding time control points breeding, carry out lambing at 3 lambing time control points, wean at 3 weaning time control points; Enforcement is needed to breed supplementary measures between described breeding, lambing and weaning time point; Described 3 breeding time control points are March, October and June in next year respectively; Described supplementary measures of breeding comprise breeding ram supplementary feeding, basic ewe nutrition regulation and weaned lamb and fatten.
Preferably, at described 3 ~ 7 years old ram age of breeding, body weight is not less than 50kg, and supplementary feeding scheme is: day feeds mixed concentrate (corn, oat or high-quality dregs of beans) 0.8 ~ 1.2kg, 1 ~ 2 piece, egg, carrot 0.5 ~ 1.0kg, green hay free choice feeding.
Preferably, breeding male and female sheep quantitative proportion 1: 30 ~ 40; Described breeding ram grows good, healthy, has Seed practical value.
Preferably, in 3 ~ 8 years old age sheep year of described basis female, body weight is not less than 48kg, nutrition regulation is take supplementary feeding measure May in October to next year, mixed concentrate (corn, oat or high-quality dregs of beans) 0.3 ~ 0.5kg, carrot 0.2 ~ 0.5kg, salt 5 ~ 10g and appropriate high-quality hay.
Preferably, described 3 lambing time control points are August, March in next year and November in next year respectively; 8 monthly output summer lambs, next year 3 produces spring lamb per month, next year 11 produces winter lamb per month.
Preferably, described 3 weaning time control points are October, June in next year and February in next year respectively; Described lamb more than litter weight at birth 3.5kg, and ensure to have colostrum, be born and train the material that pastures afterwards in 10 days, be born to mend every day after 20 days and feed fine fodder (oat or corn) 50 ~ 100g.
Preferably, described breeding time and weaning time interval 15 ~ 30 days; Described lambing time control point to the number of days at weaning time control point is: 50 ~ 60 days, summer lamb interval, 80 ~ 90 days, winter lamb interval, 60 ~ 80 days, spring lamb interval.
Beneficial effect of the present invention:
The Tibetan sheep breeding mode of the present invention's tissue, fully can excavate the breeding potential of breeding sheep, improves the reproductive efficiency hiding sheep, and be conducive to the quantity increasing flock of sheep, sheep composition of livestock herds is hidden in adjustment, improves and hides Productive Performance of Sheep.Its production efficiency produced system than 1 year one increase by 35% ~ 40%, and reproductive survival rate improves 10% ~ 15%.Within these 2 years 3, produce the method improving and hide sheep reproductive efficiency, be suitable in Tibetan sheep seed selection and use in producing.
