Abstract
Provided is a vagina embolism device for yak synchronization of estrus and a preparation method of the vagina embolism device for yak synchronization of estrus. The vagina embolism device of yak synchronization of estrus is in a Y shape and is composed of a plastic skeleton, silicon rubber medicine slow release caps and a plastic digging rope. Two cylinder slice layer shape silicon rubber medicine slow release caps are sleeved on two upper forks of the Y-shaped plastic skeleton. The cylinder slice layer shape silicon rubber medicine slow release caps are prepared by mixing silicon rubber, flurogestone acetate powder and stearic acid modifier according to a ratio and through injection molding. Flugestone hormone is utilized to inhibit natural estrus action of the yak, when the action is relieved, the yak group can rut synchronously and a goal of artificial control of animal estrus can be achieved.
Description
Technical field
The invention belongs to the animal husbandry field, relate to a kind of for yak estrus synchronization vaginal suppository plug device and preparation method.
Background technology
Yak is the peculiar cattle kind of extremely frigid zones, the phytophage ruminant domestic animal.Yak is the mammal that lives in the world the height above sea level highest point.Chinese Qinghai-Tibet height above sea level is mainly originated in regional more than 3000 meters in nearly 1,200 ten thousand of China.Adapt to high and cold ecological condition, anti-thick, endure hardships, be apt to away danger road, abrupt slope, snow mountain marsh, can swim the river torrent of crossing a river, the title of " yak " is arranged.
The yak whole body is all precious.The Tibetan people clothing, food, lodging and transportion--basic necessities of life are burnt to plough and are all be unable to do without it.People drink yak milk, eat Carnis Bovis grunniens, burn the yak excrement.But its hair tailoring or tent, skin is the good material of process hides.It both can be used for agro-farming, again can be at high original work means of transport.
The breeding of yak has obvious seasonality, and rutting concentrates on 7,8,9 three months, and female yak is in whole sexual season, and majority is only oestrused once, and the estrus cycle is very inconsistent, individual variation great disparity, and short person 5～6 days, elder be more than 60 days, average 21 days.Duration of estrus, is the same with the estrus cycle inconsistent, average out to 41.6 hours.2 years tires of common female yak or 3 years two tires, 1, every tire, the 2nd year rutting after general calving.Cause with first-class reason yak the difficulty of becoming pregnant, breeding potential is low.Therefore, do a good job of it the breeding work of oestrusing for the first time, significant to the breeding potential that improves yak.
In addition, Alpine Grasslands, autumn in summer herbage growth is in great numbers, supply more sufficient, Winter-Spring herbage quanlily wretched insufficiency, Quality Down.the natural meadow herbage quanlily, the quality supply has very large undulatory property in the whole year, this contradiction has caused the forage grass supply uneven season, it is to live in pastoral area, the grassland grazer summer, autumn is fertile, winter is thin, the immanent cause that spring is dead, avoid high temperature or severe cold season, make yak concentrate on benign climate, the calving in season that fodder grass is abundant, estrus time that will the manual control cow, reach concentrated rutting, concentrate the purpose of calving, so greatly improve the survival rate of calf yak, facilitate feeding and management, use manpower and material resources sparingly, this is also the main cause that present technique is implemented.(analysis of Chinese grass-land deterioration and Preventing Countermeasures thereof, 05 phase of " ecological economy " nineteen ninety-five).
Summary of the invention
Cause in order to solve yak become pregnant difficulty and inconsistent problem of estrus cycle, the invention provides a kind of yak estrus synchronization vaginal suppository plug device and preparation method, be characterized in that embolization device is " Y " shape structure, is comprised of plastic skeleton, silicone rubber medicine slow release cap and plastic pull tie.Plastic skeleton keeps the thromboembolism global shape, moulds on material skeleton two forks at " Y ", overlaps two cylindrical silicon rubber medicament slow release caps, the effect of silicone rubber medicine slow release cap performance biological function.
The preparation of silicone rubber medicine slow release cap mixes injection molding by two component vinylsiloxane rubbers, silicone rubber crosslinking agent, flurogestone acetate powder and stearic acid modified dose by proportioning and forms.The base molecule structure of two component vinylsiloxane rubbers is HO (MeRSiO) n, silicone rubber crosslinking agent molecule formula Si (OR)

Mould on material skeleton two forks at " Y " during use, overlap two cylindrical silicon rubber medicament slow release caps, plastic pull tie is fixed on " Y " and moulds material skeleton lower fork, then be placed on the intravaginal deep of female yak that oestruses, the general sustained release of placing after 9～12 days is completed, and holds plastic pull tie thromboembolism is pulled out.
Description of drawings
Fig. 1 is yak estrus synchronization vaginal suppository plug device method schematic diagram of the present invention
As shown in Figure 1, the combination of this embolization device is " Y " type, plastic pull tie 1 is fixed on the lower fork foot of Y plastic skeleton 2, two silicone rubber medicine slow release caps 3 of cover on 2 two upper fork feet of Y plastic skeleton, three kinds of unit constructions become yak estrus synchronization vaginal suppository plug device, during use, two silicone rubber medicine slow release caps, plastic skeleton and plastic pull tie assembling parts are got up to get final product.
The specific embodiment
Silicone rubber medicine slow release cap is the funtion part of embolization device, cylindrical lamellar structure, long 7cm, diameter 3cm, preparation mixes injection molding by double-component high-strength vinylsiloxane rubber, silicone rubber crosslinking agent, acetic acid progesterone powder and stearic acid modified dose by the quality proportioning and forms.During making at normal temperatures with the high strength vinylsiloxane rubber approximately 25～35g, silicone rubber crosslinking agent approximately 25～35g, flurogestone acetate powder 1000～600mg and stearic acid modified dose of 2～4g mix and blend are mixed well, notice that stirring reduces air as far as possible and enters, then inject the approximately steel die of 50 ℃, after solidifying through 5～10 minutes, demoulding takes out.
Plastic skeleton and plastic pull tie are to form with the vinyon mold injection.Plastic skeleton is " Y " shape, length and width 12 * 10cm, two long 9.5cm of clubfoot.The long 30cm of plastic pull tie.
Yak estrus synchronization vaginal suppository plug device gets up two silicone rubber medicine slow release caps, plastic skeleton and plastic pull tie assembling parts in use, smear lubricant on the cap surface, input yak intravaginal external os of vervix place, medicine slowly releases in intravaginal, by the vaginal mucosa absorbed into serum, play a role, generally place after 9～12 days drug release and complete, hold plastic pull tie thromboembolism is pulled out.
The invention has the beneficial effects as follows, by yak estrus synchronization vaginal suppository plug device is installed, flurogestone acetate suppresses the yak spontaneous estrus, and in a single day this effect is removed, and the yak group energy is oestrused simultaneously.Estrus synchronization is a kind of method that manual control animal oestruses, and the large activation of the cow that a group different times is oestrused is oestrused in same time, can accomplish like this to breed simultaneously, calving simultaneously, save labour, material resources, improve the efficiency of management, improve the survival rate of young stock.
