Sheep farmers hope that their own sheep can bring greater economic benefits. In fact, as long as the key farming techniques are mastered, it is not difficult to improve the efficiency of mutton farming. Today, Hui Nong Network Xiaobian will talk to you about the key technologies to improve the efficiency of mutton sheep breeding.
1. Site selection and construction of sheep farm
When selecting a site for a sheep farm, it should be as close as possible to a distance of 500 m or more between the residential area, the water source and the main road. Choose a place with a strong shelter from the wind, the sun, and the grassland, and improve the water, electricity and traffic roads. Infrastructure construction.
The construction of the sheep farm requires a distance of 2~3 m between the ground and the height of the sheep house, and the slatted plate is installed inside the sheep house at a distance of 50 cm from the ground. The movable plate can be installed to facilitate cleaning and cleaning. At the same time, the fattening house, the breeding house and the nursing house should be isolated and a sports field should be set up.
2, the choice of sheep
Breeding breeds of mutton sheep must be considered in combination with the local hydrology, climate and grassland resources, and select better breeding species. The breeding methods of meat sheep are mainly divided into the following two types.
(1) Mountain-fed mutton sheep breeding
In the case of mountain stocking, it is generally possible to select a variety of heat resistance, wide adaptability, high economic value and hybridity advantage, and a hybrid of Boer goat or Boer goat can be selected. Boer goat is known as the “King of Meated Goats†and is a relatively famous goat breed. Its characteristics are: large size, fast growth, strong fertility, high meat production efficiency, resistance to rough feeding, high slaughter rate and disease resistance. Strong and hereditary stability.
(2) Variety selection of sheep in the shed
In the shed culture of mutton sheep, sheep can be selected for breeding, such as small-tailed Han sheep and Charolais sheep. Small-tailed Han sheep has the characteristics of maturity, multiple births, fast growth, large body, large meat production, hereditary stability, strong adaptability, etc. It can be used for fattening at 4 months of age, and the annual output rate can reach more than 400%. It is a famous animal in China. Good seed. Xialuo has the characteristics of early maturity, rough feeding, strong feeding ability and good fattening performance. The slaughter rate is 50%, which is one of the best meat sheep breeds.
3, lamb fattening and slaughter
(1) Adjust lamb feed and nutrients
Lamb feed should be adjusted according to its growth stage. For example, lambs under one month of age should be weaned in advance. In daily feeding, attention should be paid to the supplement of protein powder, fried soybean powder, wheat flour, cod liver oil, salt and various trace elements. The lamb grows and increases the nutrients in the feed. Lambs that are not weaned early can feed their own grass at 10 days of age, and can be reared at 20 days of age with wheat flour or corn flour supplemented with trace element additives.
During the feeding process, it is necessary to pay attention to the cleanliness of the lamb's drinking water to avoid disease. Within 2 weeks of the birth of the lamb, the lambs need to be injected with sodium selenite and VE in a scientific and reasonable way. After that, the lambs need to be supplemented with selenium regularly. The artificial injection method or the additives can be mixed into the feed.
(2) Scientific weaning of lambs
After the lamb grows to 7 weeks of age, the rumen can digest the roughage, so the weaning of the lamb can be carried out after it grows to 2 months of age. At the same time, the lamb after weaning needs to adjust its feed ratio, pay attention to the supplement of various nutrients. .
(3) Proper grazing
When the lamb grows to a stage where grazing can be carried out, the grassland with abundant grass can be selected for grazing. The daily grazing time can be controlled at around 8h, and the feed structure can be scientifically and reasonably adjusted according to the different stages of its growth. nutrient.
4. Feeding and management of adult meat sheep
(1) Breeding and lambing schedule
In the breeding of mutton sheep, it is necessary to pay attention to the rationality of breeding and lambing time. In the breeding season, the seasons with relatively mild climate and temperature change should be selected to arrange the lambing time, and the breeding time will be arranged in August-October. Make sure the lamb is born in a season where climate and temperature are more appropriate.
(2) Feeding and management of pregnant ewes
Ewes need more scientific and rich nutrients during pregnancy, which has a greater impact on the growth of lambs. In the gestation stage of the ewes, it is necessary to fully supplement the nutrition, pay attention to the timely supplement of calcium, selenium, phosphorus and other elements to ensure the lamb's strong physique and improve disease resistance.
(3) Disease prevention and control methods for mutton sheep breeding
In the breeding of mutton sheep, it is necessary to pay attention to the living environment of the flock, clean up and clean the pastures and pens in time, ensure the clean environment of the living environment, and reduce the chance of disease in the sheep.
The above is the key technology to improve the efficiency of mutton sheep breeding by Huinong. In the end, Xiaobian wants to say that the breeding of mutton sheep has the characteristics of less investment and less risk. As the market demand for mutton sheep continues to increase, the science of mutton sheep Farming is becoming more and more important. In the breeding work of mutton sheep, it is necessary to combine the local conditions as much as possible, reasonably select the breed of mutton sheep, carry out scientific site selection and construction of the sheep farm, and raise the sheep according to the different growth stages of the sheep in a scientific way. Breeding benefits.
