SUMMARY OF THE INVENTION: the method consists in mating a sheep in two stages within the reproductive season, embracing in the second stage aborted or selected from the reproduction lines of queens and rock. In queens who have rotted in non-traditional terms, one week before weaning, they reduce feeding rates by 40-45%. On the fourth day after weaning, the oppression of these uterus is transferred to high-protein feed. And weaning is carried out at two months of age.

Description

Изобретение относитс к сельскому хоз йству , в частности к способам воспроизводства овец.The invention relates to agriculture, in particular to methods for reproducing sheep.

Целью изобретени вл етс обеспечение высокого выхода полноценных гн т и уменьшение затрат на воспроизводство. Поставленна цель достигаетс тем, что в пределах полового сезона провод т случку овец в два этапа, охватыва во втором этапе абортировавшихс и выбившихс по различным причинам из линий воспроизводства маток и рок, а гнение провод т в пределах сезона и вне сезоне окота.The aim of the invention is to provide a high yield of full yoghurt and reduce reproduction costs. The goal is achieved by the fact that during the reproductive season sheep are mated in two stages, embracing in the second stage aborted and dropped out of the reproduction lines of uterus and rock for various reasons, and rotting is carried out within the season and out of lambing season.

Согласно предложенному способу в половой сезон на 40 - 45 день случки прекращают осеменение и дальнейшую дочистку овец баранами. А в конце полового сезона (декабрь) провод т осеменение не оплодотворившихс или не созревших на первом этапе, а также абортировавшихс маток и дочистку их баранами..According to the proposed method, during the reproductive season, 40 to 45 days of mating, the insemination and the further cleaning of the sheep are stopped by sheep. And at the end of the sexual season (December), insemination of the non-fertilized or not matured at the first stage, as well as the aborted queens and their cleaning by sheep are carried out.

Ягнение основной группы маток провод т в течение 45 - 50 дней в прин тые в хоз йствах сроки (декабрь - нварь).Lambing of the main group of uterus is carried out for 45-50 days at the time taken at the farm (December - January).

В начале ма из поголовь маток, слученных в конце полового сезона, отбираютAt the beginning of the ma, from the stock of queens that occurred at the end of the sexual season, they are selected

котных за 10 дней до начала гнени и формируют отару оплодотворившихс маток. Отъем гн т, который по времени совпадает с началом полового созревани овцематок, провод т в двухмес чном возрасте. При этом за 6 дней до отъема гн т к маткам подпускают баранов и уменьшают нормы кормлени маток на 40 - 45%, одновременно в таком же соотношении увеличивают энергетическую ценность рационов гн т. kittens 10 days before the start of the nest and form a flock of fertilized queens. Weaning, which in time coincides with the onset of puberty of the ewes, is carried out at two months of age. At the same time, 6 days before weaning, the rams are allowed to enter the uterus and the uterine feeding rate is reduced by 40-45%, while at the same time the energetic value of the rations diets is increased.

На четвертые сутки после отъема маток перевод т на кормление высокобелковыми кормами. При этом происходит эффект фланшинга на фоне искусственно заниженного уровн кормлени . С этого же периода начинают выборку маток в охоте и осеменение.On the fourth day after weaning, the mothers are transferred to high-protein feed. In this case, a flushing effect occurs against the background of an artificially lowered level of feeding. From the same period, sampling of queens in hunting and insemination begin.

Предложенный способ позвол ет повысить выход гн т на 10 голов в расчете на 100 голов овцематок, уменьшить затраты на выращивание молодн ка до 7 рублей в расчете на одну голову.The proposed method allows to increase the yield of breeders by 10 goals per 100 heads of ewes, and reduce the cost of rearing young animals to 7 rubles per one head.

Случка овцематок, объ гнившихс вне сезона, мину традиционные сроки подготовки матки к случке (40 - 45 дней) и исключа стимул цию охоты с гормональнымиA case of ewes that rotted out of season, bypassing the traditional time for preparing the uterus for a mating (40 - 45 days) and excluding the stimulation of hunting with hormonal

Пример Наовцекомплексе колхоза Путь Ленина Прохоровскогоо района Белгородской области в половой сезон с 10 июл по 11 сент бр проводили случку овец. В отаре Маслова А.В. за этот период было случено 996 овцематок из 1030 голов. С 25 но бр по 8 декабр были случены овцематки , неоплодотворившиес в основной случ- ной период и абортировавшиес . В этом цикле были случены 94 головы, повторно пришедшие в охоту, и 36 голов, не пришедшие в охоту на первом этапе. С 18 декабр по 13 феврал объ гнилось 834 овцематки, которые принесли 940 гн т,An example of the Navovsekomplex of the collective farm Lenin's Prokhorovsky District of the Belgorod Region during the sexual season from July 10 to September 11, carried out the mating of sheep. In the flock Maslova A.V. during this period, 996 ewes out of 1030 animals were killed. From 25 November to 8 December, ewes were infertilized in the main random period and aborted. In this cycle, 94 heads that repeatedly came to the hunt, and 36 goals that did not come to the hunt in the first stage, were observed. From December 18 to February 13, 834 ewes were rotten, which brought 940 gn,

В конце апрел отобрали котных маток и сформировали отдельный сакман. Из 140 голов, пришедших в охоту в конце полового сезона, объ гнилось 106 голов, которые принесли 119 гн т.At the end of April, the kitten queens were selected and a separate sackman was formed. Of the 140 goals that came to the hunt at the end of the sexual season, 106 were rotted, which brought 119 gn.

В целом в течение сезона гнени и вне сезона гнени объ гни ось 940 овцематок и принесли 1068 гн т. Из них 884 гненка были отбиты от маток на первом этапе в возрасте 2,5-3,0 мес. Ягн та второго циклаOn the whole, during the nest season and outside the nest season, the axis rotted 940 ewes and brought 1068 gn. Of these, 884 gnats were repelled from the uterus at the first stage at the age of 2.5-3.0 months. The lamb of the second cycle

-в количестве 115 голов были отбиты в возрасте 2,0 мес. При этом за 6 дней до отъема к маткам подпустили 3 барана, уменьшили рацион кормлени маток с 1,8 кор.ед. в расчете на одну голову в сутки до 1,2 корм.ед.-in the amount of 115 goals were repulsed at the age of 2.0 months. At the same time, 3 sheep were allowed to enter the uterus 6 days before weaning, and the uterine feeding ration was reduced from 1.8 bark units. per one head per day, up to 1.2 feed units

Claims

SUMMARY OF THE INVENTION A method for reproducing sheep, including mating of ewes, their rotting and weaning, characterized in that, in order to increase the yield of males, the mating of ewes is carried out in two stages during the reproductive season by repeatedly involving aborted or knocked out males

At the same time, the nutritional value of the diet was increased from 0.4 to 0.6 feed units. On the fourth day after weaning (from July 15), the uterus was transferred to abundant

feeding with high-protein feed with the inclusion of feed and alfalfa in the diet.

From July 20, they begin sampling of queens in hunting and insemination. 40 days of insemination

out of 820 heads rotted in the first cycle, 869 goals or 98% came into the hunt. This rate among the uteri that were rotten in the second cycle was 95%. The total percentage of sheep who came to the hunt in the flock was also 95%.

A comparative analysis of the effectiveness of this method and technology adopted in the economy showed the advantages of the former. In the first case, the total yield of prey for weaning was 996 goals, or 97%. Weight oppression for weaning, per head was 23.4 kg.

In the control flock, when organizing the reproduction of sheep according to the technology adopted by the economy, the yield of yam at birth was 93%, and the safety of yam from birth to weaning was only 88%, and therefore the yield of yam to weaning was only 83% . Mass oppression to weaning in this

the flock amounted to 21.1 kg.

lines of reproduction of ewes, while in uterus that have rotted in an unconventional time, a week before weaning, they reduce feeding norms by 40–45%, on the fourth day after weaning, they are transferred to high-protein feeds, and weaning carried out at two months of age.
