Nine keys should be grasped in the recommendation of raising sheep.

"stationmaster Li, this year we want to expand the scale of raising Nanjiang yellow sheep, but there is a shortage of forage resources. We are going to plant some forage grass. Please tell me how to grow forage grass." Recently, when Li Mingquan, director of the animal husbandry station and pastor of Shahe Town, Nanjiang County, Sichuan Province, came to Wulang Village, several sheep farmers surrounded the stationmaster Li not only to raise sheep technical materials, but also asked him to talk about forage planting techniques. Stationmaster Li simply gave a lesson on forage planting technology on the spot. Lao Li said that there are "six keys" to forage planting.

The first thing to choose to plant forage grass is to choose a more fertile field, not to use barren and thin soil just because it is recommended. At the same time, the fields close to the sheepfold should be selected. if the grass is far away from the farm, it will require a lot of labor to collect grass and increase the cost.

The varieties were selected from March to May in spring, mainly planting Gaodan grass and a small amount of ryegrass, and mainly planting ryegrass and forage radish from August to October in autumn.

Planting method: 2 kg ~ 3 kg seeds per mu for Gaodan grass and 2 kg ~ 2.5 kg seeds per mu for ryegrass. The land where forage grass is planted must be fully fertilized before ploughing and leveling, and then sowed or sown with 1 meter open box or strip sowing. The sowing depth is 3cm ~ 4cm, if it is too deep, the seed should not grow up.

Field management Gramineae forage grass in jointing, heading, cutting, mainly nitrogen fertilizer, urea 5 kg per mu, weeds must be controlled. Artificial weed control is mainly used for small area plots, and herbicides can be selected for large area plots, but the operation should be carried out in strict accordance with the instructions. Timely irrigation of forage grass is needed in arid areas and dry season. Irrigation after mowing combined with topdressing can promote forage regeneration and increase grass yield.

The best cutting height for forage harvesting and storage Gaodan grass is more than 1 meter, and ryegrass is cut at heading time. The grass planted in spring is mainly sun-dried hay, supplemented by silage, and fed mainly by fresh grass to sheep in autumn.

The method of making hay is to mow the grass in summer and autumn, spread the grass in the same place or another highland, and turn it every other day to accelerate water evaporation. Generally mowed forage grass can be bundled and stored in a ventilated and dry place after drying for 3 ~ 4 days.

Silage is a technology that uses microbial anaerobes to ferment and restrain the growth of harmful microorganisms to preserve the nutrition of high-quality artificial forages. First, it is necessary to prepare the silage pond to ensure that there is no water leakage and air leakage, and build the silage pond according to the feeding scale, usually in the range of 10 cubic meters to 30 cubic meters. Second, the forage grass must be cut at the right time and cut into 2 cm ~ 6 cm sections to ensure that the moisture is about 70%. Third, the silage must be filled and compacted in the silage tank, which must be packed into a circle, the dome must reach 10 cm ~ 20 cm from the mouth of the pool, and the dome must be sealed with a polyethylene film 0.2 mm thick, which can be used after 40 ~ 50 days of fermentation. silage must continue to be sealed after it is removed.

If the forage grass after harvest has dew or high moisture content, it should be dried before feeding. If the sheep are fed with more grass, some high-quality hay should be added. Goats are mainly fed with forage grass and an appropriate amount of fine fodder. generally, each goat is fed with 5 kg ~ 8 kg fresh grass and 150 g ~ 250 g concentrate per day, and the forage is fed regularly and freely, usually 2 ~ 3 times a day. Feed concentrate once, feed less frequently, grass first and then feed. In addition, it is necessary to set up a drinking tank to let the sheep drink freely, and the hay had better be beaten into grass powder and mixed into the concentrate for feeding.

Supplementary feed concentrate reference formula corn 60%, soybean cake 10%, rapeseed meal 5%, wheat bran 13%, rice bran 10%, salt 1%, calcium bicarbonate 1%. 1-week-old lambs can be induced with high-quality grass or hay. After 20 days of age, a small amount of concentrate was fed, initially 5 grams per day, then increased day by day, and weaned from 2 months to 3 months old.
