Fresh feed using TXY China Feed Industry Information Network - based on feed, serving animal husbandry
1. During the harvesting period, the leguminous forages used for fresh feeding are harvested earlier, generally in the early bud stage to the bud stage, which is suitable for castration, and harvested 3 to 4 times a year. Sudan grass and its hybrids and forage sorghum should be harvested at the beginning of the booting stage or earlier. The final harvesting period should not exceed the late heading stage and harvest 1 or 3 times a year. Scorpion should be castrated at the booting stage, and the final cut-off period should not exceed the maturity period, harvesting 2 or 3 times a year.

2, feeding method timely harvested pastures after a little drying and directly into the animal house to feed the sheep, this feeding method is not scientific, although convenient to use, but the loss is serious. In the production, freshly harvested fresh grass is generally processed and then fed to the sheep. There are two main processing methods: one is to use a chopping machine to properly cut and then feed the sheep, and the cut length is 2 to 3 cm. The second is that the grass is smashed. For grasses with high crude fiber content such as sorghum and high danshen, the mashing with a soft crusher improves the digestibility of crude fiber, increases palatability, and improves the utilization of roughage. It is suitable to feed 10 kg of sheep per day and 8 to 9 kg of goats. The proportion of feeding is generally 30-40% for leguminous grasses, and 60-70% for feeding sorghum, Sudan grass and its hybrids and medlar.

Silage uses TXY China Feed Industry Information Network - based on feed, serving animal husbandry
1. During the harvest period, perennial leguminous grasses such as alfalfa and Sha Dawang are generally not the main raw materials for silage of individual varieties, but in some cases they must be preserved by silage. TXY China Feed Industry Information Network - based on feed, serving animal husbandry
The most suitable harvesting period for the production of silage legumes is the initial flowering period, which should not exceed the flowering period at the latest. The crude protein content in the early flowering stage is high. Although the crude protein content decreases and the crude fiber content increases during the full flowering stage, the forage yield is the highest. After the crude fiber is decomposed by silage fermentation, its palatability and utilization rate are still high. Sudan grass and its hybrids, forage sorghum and scorpion are best harvested from the earliest to the early flowering stage, and harvested at the latest.

2, silage method legumes grass is generally not suitable for silage alone, can be mixed with silage and its hybrids, forage sorghum, scorpion, silage, mixed ratio for legumes grass: grass forage 30 to 40% during the day: night 60 ~70%. Low-moisture silage can also be carried out, that is, the moisture content of the raw material is reduced to 45-55% for silage. Silage can be produced separately from Sudan grass and its hybrids, forage sorghum and scorpion. Commonly used silage facilities mainly include silage, plastic bag silage and stretch film silage.

3, feeding method TXY China feed industry information network - based on feed, service animal husbandry
(1) The daily feeding amount of silage, the daily feeding amount of sheep is 4 to 5 kg, and the goat is 3 to 4 kg. TXY China Feed Industry Information Network - based on feed, serving animal husbandry
(2) Silage, when feeding pregnant sheep, it should be noted that it is not suitable for feeding 20 to 30 days before and after delivery, nor can it be fed with frozen silage to avoid abortion. TXY China Feed Industry Information Network - based on feed, serving animal husbandry
(3) Silage, which cannot be fed separately, should be mixed with other feeds in a certain proportion, generally not exceeding 50% of the sheep diet. TXY China Feed Industry Information Network - based on feed, serving animal husbandry
(4) Take out the actual feed intake of the sheep every day, and use it as needed to minimize the storage time and avoid secondary fermentation. Silage that has not been eaten by livestock in the trough should be removed in time and cannot be returned to the silage container.

Hay uses TXY China Feed Industry Information Network - based on feed, serving animal husbandry
Hay refers to the forage that can be preserved for a long time after natural or artificial drying, so that the water is reduced to 17% or less. It is the main roughage for the winter and spring of the sheep. TXY China Feed Industry Information Network - based on feed, serving animal husbandry
1, hay processing TXY China feed industry information network - based on feed, service animal husbandry
Alfalfa, medlar, sudangrass and their hybrids can be processed into high-quality hay. After drying with sorghum, the dry matter in the dry matter has low crude protein content and high crude fiber content, which is generally not suitable for processing hay products. TXY China Feed Industry Information Network - based on feed, serving animal husbandry
Alfalfa is used for processing hay. The harvest period is generally from the bud stage to the initial flowering stage. At this time, the harvest can ensure the quality and yield of the grass product. The suitable cutting period for scorpion, Sudan grass and its hybrids is the heading date. TXY China Feed Industry Information Network - based on feed, serving animal husbandry
The hay processing method generally adopts the natural drying method, that is, after the suitable harvesting of the forage grass, the ridges are sown into grass scorpions, spread out on the spot, spread as much as possible, and turn over the sun according to the dry condition, so that all the grasses in the grass scorpion They are fully exposed to dry air. After drying for 6 to 7 hours, the alfalfa shall be bundled into bales weighing about 1-2 kg, and the grasses shall be bundled into bundles weighing about 4 to 5 kg, and the grass shall be piled into a "human" shaped haystack and dried. After 36 to 48 hours, the forage stalks are easily broken by hand, and the green hay with a water content of 15 to 17% is prepared.

2, feeding method TXY China feed industry information network - based on feed, service animal husbandry
There are two main types of hay feeding, one is direct feeding of hay and the other is short feeding. After the processed hay is stored for a period of time, it is fed according to the daily demand of the sheep. Generally, the hay bales are opened and directly thrown into the sheep house or trough, and the sheep are free to eat. This feeding method is simple, but the loss of pasture is about 5-10%. In production, generally take short feeds, first use the grass mower to cut the hay into grass segments, and then feed. Grazing grasses are usually cut into 2 to 3 cm and legumes are 1 to 2 cm. The proportion of legume hay fed sheep is generally no more than 30% of the diet, and grasses are free to eat. TXY China Feed Industry Information Network - based on feed, serving animal husbandry
