Technical Field

The invention relates to the technical field of animal husbandry and veterinarian, in particular to an artificial delivery assisting technology for alpaca dystocia.

Background

The alpaca belongs to camelidae animals of Artiodactyla in mammalia, has pregnancy period generally over 330d, produces single fetus, and can be bred for farrowing in all seasons. The large-scale introduction of Shanxi, Gansu, Xinjiang, inner Mongolia and the like is realized in China. The introduced land is generally dry and comfortable in summer and cold and dry in winter. Meanwhile, the grazing area is large, good grazing conditions are provided, and the alpaca forages and chases in the wild or the grazing place for a long time. The farrowing generally breaks away from the group, walks at any time on a large fence, a sports ground or a pasturing ground, lies when in time, continuously adjusts the body position, has long labor process, reports about the labor process within 2-5h, and rarely causes dystocia. In recent years, with the rise of alpaca fever, a few alpacas have been introduced to many southern areas to be raised in zoos or villages for viewing. Equipped with the necessary facilities, there are generally smaller houses and playgrounds with enclosures. Sometimes alpaca farrowing exists, whether the alpaca is difficult to judge when the alpaca farrowing occurs in hot summer, a treatment guide does not exist when the alpaca farrowing occurs, and veterinarians mainly refer to the alpaca farrowing time in the northern area and a method for treating the alpaca farrowing, and often miss the optimal farrowing exploration time; meanwhile, the operation difficulty is high by adopting a rear-drive bed-lifting artificial midwifery mode, and the fetal position is not easy to correct. The difficult-to-produce alpacas are mostly dragged into the cesarean section, resulting in low success rate and more death cases of female and young alpacas.

Disclosure of Invention

In order to solve the problems in the prior art, the invention aims to provide an artificial delivery assisting technology for alpaca dystocia.

In order to achieve the purpose, the invention provides an artificial delivery assisting technology for alpaca dystocia. The process comprises the following steps: and early-stage examination including the temperature and grazing condition, the health condition, the labor process environment and the labor process condition in the previous week of the labor process, so that the time node for exploring the difficult labor is determined, and the time node is the labor process 2h in the extremely hot and narrow environment. The posture control comprises the posture of the dystocia alpaca during delivery assistance and the standing position of delivery assistance personnel. Delivery-assisting manipulations, including in vitro muscle relaxation and delivery channel internal manipulations; postpartum care, including nursing female alpaca and nursing alpaca (figure 3).

Preferably, the weather condition, grazing condition, health condition and colony condition of the alpaca one week before delivery are traced for judging how long the alpaca is not delivered, and the fetal position inspection is carried out when the alpaca is not delivered for 2 hours after the delivery process under the environment temperature of 30-33.5 ℃ and the narrow space according to the case.

Preferably, when the artificial birth canal fetal position examination is determined to be implemented, the rear legs of the lying female alpaca are firstly bound by the ropes in an 8-letter method in a ring mode, the tightness is based on the distance between the two rear feet being 2 times of the distance between the two rear feet, and the tightness is proper. The alpaca is then lifted and held in a standing position (see fig. 1 a).

Preferably, the examiner stands on the side of the alpaca, cleans the hand with warm soap water, then trims the nail and grinds the nail to a round shape, cleans the alpaca water gate with warm soap water, and wipes the alpaca water gate dry. The five fingers are closed together (fig. 1b) and slowly extend into the alpaca birth canal. After reaching, the thumb and little finger are closed and the other three fingers are touched (FIG. 1 c).

Preferably, artificial delivery assistance is performed on the alpaca according to the feeling result. When the alpaca is kept standing, the user pushes backwards along the abdomen from the neck-back connection part of the alpaca by hand to relax the alpaca muscle, so that the alpaca initially shows pain but makes a kakakakakayake sound soon. Secondly, cleaning hands and arms with soapy water, enabling five fingers to be closed together (figure 1b), slowly extending into an alpaca birth canal, enabling the thumb and the little finger to be closed together (figure 1c), enabling the other three fingers to be combined together, slowly pushing inwards from the cross-connection part (figure 21 or 2) of the neck and the foot of the alpaca, loosening hands and appropriately pulling back slightly when the alpaca is painful, and repeating the steps for a plurality of times until the delivery assistance is successful. This method is particularly effective in the crouching of the alpaca fetal head (fig. 2a) and the retrobow of the fetal head (fig. 2 b).

Has the advantages that: the invention provides an artificial delivery assisting technology for alpaca dystocia, which is suitable for the artificial delivery assisting of alpaca dystocia in extremely hot and narrow environments. Under the condition of not having sufficient instruments and equipment, the kit can timely judge the alpaca labor process condition, greatly improve the success rate of fetal position resetting and delivery assistance of the alpaca, and improve the survival rate of female alpaca and alpaca young.

Detailed Description

The present invention is further described below with reference to specific examples, which are only exemplary and do not limit the scope of the present invention in any way. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. Such modifications and substitutions are intended to be within the scope of the present invention.

An alpaca difficult-to-produce case occurs in a certain alpaca farm in the Kyoto province, Zhuhai, Guangdong province, 5 months in 2019, the weather is extremely hot in one week continuously before delivery, and the birth is 8 in the morning: 00 outdoor temperature up to 31 ℃, 10:00 reaches above 33 ℃, and has no wind, cloud and intense heat.

Librarian and store conditions: library area 50m²Left and right, separate structure, wooden floor with leaks. The temperature can only be controlled below 33.5 ℃ under the situation of full weather conditions when 3 air conditioners are installed. Two big columns and one small column are arranged in the device, and a walkway is arranged in the device. Including farrowing female alpacas, 1 male alpaca, 3 adult female alpacas and 2 young female alpacas. When female alpacas are born, due to high outdoor temperature, the grazing area is not shielded, so that other alpacas cannot be grazed and can only stay in a librarian; therefore, a hurdle is set aside for farrowing female camels, other llamas are closed on the other hurdles and walkways, and male llamas are closed independently.

Feed management and epidemic conditions

The grazing time of the alpaca flock one week before farrowing of the female alpaca is 6: 00-8: 00, 18: 00 until the automatic return of the fence, and the latest return time is generally 20: 00. The feed is normally fed, the farrowing female alpaca is shut down, the action of the spout water of the alpaca group becomes more, and the health condition is good.

Farrowing conditions. Alpaca 8: 30, beginning farrowing; 8:50 double-pin first-out and positive position; the baby can stand and walk in the process of farrowing and can be adjusted to get up and lie down. Until 10:00, the exposed part is not increased, the female sheep has slight weakness, the rising and lying adjustment times are slow, and all the others are normal. 10:40, the female sheep can be adjusted in lying state but not in standing state, and the fatigue state is obvious. 11:30, the exposed hoof part becomes cold, and the alpaca is no longer blame.

Changes in body temperature and respiration (hourly monitoring)

The body temperature is mainly detected by a groin touch method, and low temperature is mainly prevented. The body temperature is slightly increased in the early stage, and tends to be decreased after the alpaca is adjusted to lie.

Breathing changes: the number of breaths starts to rise slowly and then falls slowly as the effort becomes smaller.

TABLE 1

Mental state change conditions: compared with the alpaca born on the grassland at the beginning of the year, the mental states of the female alpaca born in the high-temperature narrow environment are obviously different.

Mental status of grassland farrowing ewes: the infant is firstly held in the four positions for inspection, then reaches the selected farrowing positions in the previous days, or gets up or lies down or walks around the farrowing points within 20m, is calm and is slightly excited. The delivery distance is as long as 5 hours, and finally alpacas are successfully delivered, and other alpacas are not observed in the grazing place.

Mental state of female sheep and camel born in the library house: in the early stage, it is also the east-dress west-desire with the desire to go to the fence, or to get up or lie down and adjust the posture. In the later period, the labor is exhausted, almost still, the state of mind is helpless and panic exists; other alpacas can look at and spray the mouth water mutually, but can not spray the mouth water to the farrowing female alpacas.

Diagnosis of a condition

Insufficient productivity, malposition, dystocia, and the alpaca has died.

Handling a condition

Artificial midwifery

Prenatal preparation. Midwife washes clean both hands with warm soap water, cuts short nails and grinds flat. Cleaning the ewe camel water gate with warm soapy water, and wiping to dry.

And detecting the tire position by touch. The 8-shaped ring binding method binds the two legs behind the alpaca, is loose and proper, and lifts the alpaca to keep the alpaca in a standing position, and the fingers are closed together and slowly extend into the alpaca from the birth canal. After entering the birth canal, the thumb and the little finger are closed together, and the fetal position of the alpaca is explored by the other three fingers. Checking to find the feet are in correct position and in proper order; but the head is not orthostatic with both feet, but is instead bowed backwards.

Midwifery

Adjusting the position of the midwifery. Keeping the alpaca standing, pushing backwards along the abdomen from the neck-back connection part of the alpaca by hand to relax the alpaca muscle, so that the alpaca initially shows pain and quickly generates a kakakake sound.

Methods for assisting delivery. Continuously washing hands and arms with soapy water, slowly extending into the alpaca birth canal, holding the thumb and the little finger together, slowly pushing inwards from the neck and foot cross-linking part of the alpaca baby with the other three fingers, loosening hands and slightly pulling back when the alpaca shows pain, repeating the steps for 3 times, and successfully helping the alpaca to give birth.

Female alpaca condition. The female sheep has fatigue, and the initial breathing is relatively fast, sitting posture and no lying down.

Anal temperature and respiration change after female alpaca delivery

TABLE 2

	Successfully help postpartum for 0.5h	Successfully help postpartum for 2 hours
			Anal temperature (. degree.C.)	36.5	35
Breathing (times/min)	33.5	30

Alpaca young condition. The death time of the alpaca is short, the tissue is soft, and the placenta is fresh.

Postpartum treatment and nursing of ewe camel

The veterinary lincomycin hydrochloride injection (10 ml: 0.6g) and the veterinary houttuynia cordata injection (10 ml) are injected intramuscularly and are used for two days once a day.

The alpaca has extremely strong recovery capability, and the proper delivery assisting technique basically has no harm, does not need special care and only needs to keep one single pen. The inspection of the next day and the third day shows that the water gate has no abnormal secretion and no odor; the female alpaca can recover health quickly.

In a very hot environment, the female sheep has a very fast decline in productivity, and after 2 hours, the female sheep is extremely tired. The alpaca farrowing has the self-body position adjusting capacity, generally moves around the center within the range of 20-30m, and limits the body position adjusting capacity of female alpaca in a narrow environment. Therefore, under a hot and narrow environment, the alpaca production condition can be judged within 2 hours, and the alpaca can be timely treated.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all the equivalent alpaca dystocia manual midwifery posture control or equivalent manipulation made by using the contents of the present specification and the attached drawings are included in the scope of the present invention.
