Abstract
Provided is a vagina embolism device of cow synchronization of estrus. The vagina embolism device of cow 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 vinyl silicon rubber, silicon rubber cross-linking agent, flugestone powder and stearic acid slow-release formulation according to a ratio and through ejection molding. When the vagina embolism device of cow synchronization of estrus is used, all parts are assembled and placed in the vagina of a cowinestrus and taken out in 10 to 15 days. Flugestone hormone is utilized to inhibit natural estrus action of the cow, when the action is relieved, the cow group can rut synchronously, and a goal of controlling animal estrus through manual work can be achieved.
Description
Technical field
The invention belongs to the animal husbandry field, relate to a kind of for milk cattle estrus synchronization vaginal suppository plug device and preparation method.
Background technology
Milch cow is the phytophage domestic animal that China mainly raises, and milch cow is drawn mainly take Fresian as main by China, is the unique milk cattle kind of China, and this varietal adaptation is strong, have a very wide distribution, milk yield is high, crude feed tolerance.The milch cow puberty, is at 6～9 monthly ages, and is different and variant with environmental condition with raising, estrus cycle 15～24d, and the average pregnant natural law of 21d Queensland, female calf is 277.5d, bull calf is 278.7d.Since 1972 begin to use frozen semen artificial insemination, all generally used to the Fresian in big and medium-sized cities, the nineteen eighty-two whole nation and suburb.
Estrus synchronization is a kind of method that manual control animal oestruses.By utilizing the HORMONE TREATMENT milch cow, the large activation of the cow that a group different times is oestrused is oestrused in same time, and the problem of simultaneously the solution milk cow recessive being oestrused produces effect very much.Its method has two kinds: the one, use the progestogens drug treating, and the estrus cycle of cow is extended; Another kind is to process with dissolving corpus luteum class preparation, and the estrus cycle of cow is shortened.The present invention introduces a kind of milk cattle estrus synchronization vaginal suppository plug device and preparation method of processing with progestational hormone medicine.
Summary of the invention
The present invention relates to a kind of milk cattle estrus synchronization vaginal suppository plug device and preparation method, be characterized in that thromboembolism 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 cylinder lamella shape silicone rubber medicine slow release caps, the effect of rubber medicament 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 hormone powder and stearic acid modified dose by proportioning and forms.Silicone rubber is two component vinylsiloxane rubbers, and the base molecule structure 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 is placed on the intravaginal deep of cow in estrus, the general drug release of placing after 9～12 days is completed, and holds plastic pull tie thromboembolism is pulled out.
Description of drawings
Fig. 1 is milk cattle estrus synchronization vaginal suppository plug device 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 milk cattle 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 this device, cylindrical lamellar structure, and long 7cm, diameter 3cm, preparation mixes injection molding by double-component high-strength vinylsiloxane rubber, acetic acid progesterone hormone powder and stearic acid modified dose by the quality proportioning and forms.During making at normal temperatures with the high strength vinylsiloxane rubber approximately 35g, silicone rubber crosslinking agent approximately 35g, flurogestone acetate hormone powder 1500～2000mg and stearic acid modified dose of 3～5g 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 15 * 12.5cm, two long 12.5cm of clubfoot.The long 30cm of plastic pull tie.
Milk cattle 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 10～15 days drug release and complete, hold plastic pull tie thromboembolism is pulled out.
The invention has the beneficial effects as follows, by milk cattle estrus synchronization vaginal suppository plug device is installed in the milch cow intravaginal, the flurogestone acetate hormone slowly discharges, and suppresses the milch cow spontaneous estrus.After taking out thromboembolism, inhibitory action is removed, and the milch cow 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.
