Recommended techniques for raising sheep

Sheep is one of the livestock that people are familiar with, and its breeding has a history of more than 5000 years in our country. As a green breeding model, sheep breeding is becoming more and more popular, so there will be many farmers looking for better recommended sheep breeding technology. Actually, it is not so simple to do a good job of recommended sheep raising. There are many aspects that need to be paid attention to. Let's take a look at the recommended sheep raising technology.

Recommend the common sense of raising sheep

1. Suitable varieties: you can choose alfalfa, 70 pairs of rye for each grazing, and pine vanilla with leaves. Clover, Juhui grass, Rumex and other forage varieties with high yield, high quality and strong adaptability.

2. Appropriate scale: the breeding scale should be determined according to the family labor and equipment conditions, and then the planting area should be determined by the breeding scale. In general, three mu of forage grass can be used for 15-20 adult rate feed for the whole year. The breeding speed of sheep is slow, and the annual growth rate is only about 3 times of the number of ewes at the beginning of the year, so the planting area of forage grass depends on the base number of sheep and the speed of development, so that it can not only meet the supply but also avoid waste.

3. Appropriate stubble: the principle of determining the distribution of forage stubble is to increase the forage yield per unit area and ensure that fresh forage grass can be eaten all the year round. The reasonable combination of alfalfa and Dongmu 70 rye can ensure the balanced supply of four-season green feed for sheep in a year. Rumex Kmurl hybrid acid mold field interplanting Italian ryegrass or Dongmu 70 rye.

4, moderate feeding: adult sheep need about 4 kg of green feed every day, too much fresh forage is easy to cause diarrhea. In the case of sufficient fresh feed, it is necessary to appropriately increase the proportion of bran in concentrate (bran should account for about 40% of the total concentrate). Rumex K-1 hybrid Rumex has higher water content and should be properly controlled during feeding. Single feeding of alfalfa and clover is easy to cause swelling and pain, so it should be fed with other forages. The seedlings of Sudan grass and Mexican corn contain hydrocyanic acid, which should be dried and fed after harvest.

Fresh feeding and utilization technology

The main results are as follows: 1. The harvest period of legume forage used for fresh feeding is earlier, and it is generally suitable to be cut from early bud stage to bud stage, harvesting 3-4 times a year. Sudan grass, its hybrids and forage sorghum should be harvested at the early or early booting stage, and the growth period of the final harvest should not exceed the late heading stage, harvesting 1-3 times a year. Barnyardgrass should be mowed at booting stage, and the final growth period should not exceed the milk stage, harvesting 2-3 times a year.

2. Feeding method: after a little drying, the timely harvested forage grass is directly put into the barn for sheep to feed, this feeding method is not scientific, although it is convenient to use, but the loss and waste is serious. In production, the newly harvested fresh grass is generally properly processed and then fed to sheep. There are two main processing methods.

① mechanical shortening: use the cutting machine to cut it properly and then feed the sheep with a length of 2 cm to 3 cm.

② forage crushing: for forage sorghum, sorghum, sorghum and other grasses with high crude fiber content, crushing machine can improve the crude fiber digestibility, palatability and utilization rate of roughage. It is suitable to feed 10 kg of sheep and 8-9 kg of goat every day. The feeding proportion is 30%-40% for leguminous forage, 60%-70% for forage sorghum, Sudan grass and their hybrids, and barnyard weeds.

Hay utilization technology

1. Hay processing: alfalfa, barnyard, Sudan grass and their hybrids can be processed into high quality hay. The dry matter of forage sorghum has low crude protein content and high crude fiber content, so it is generally not suitable for processing hay products. The suitable harvest time of alfalfa for processing hay is generally from budding stage to early flowering stage, when the harvest can ensure the quality and yield of hay products. The suitable cutting period for barnyardgrass, Sudan grass and their hybrids is heading stage. The hay processing method generally adopts the natural drying method, that is, after the grass harvested in the right time is cut, the grass is cuddled along the ridge, spread out in the sun on the spot, spread evenly as far as possible, and turn in time according to the drying condition, so that all the grasses in the grass can be fully exposed to the dry air. After drying for 6 hours and 7 hours, the alfalfa was bundled into bundles weighing about 1 kilogram and grasses into bundles weighing about 4 kilograms, and the local code was made into a "human"-shaped haystack. After drying for 36 hours, the forage stalk was easily broken by hand and was prepared into hay with a moisture content of 15% 17%.

2. Feeding methods: there are mainly two kinds of hay feeding methods, one is hay direct feeding, the other is short feeding. After the processed hay is stored for a period of time, the sheep are fed according to their daily needs. Generally, the hay bundles are opened and thrown directly into the sheep shed or trough, where the sheep are free to feed. This feeding method is simple, but the forage loss is about 510%. In production, it is generally adopted to cut short and feed, first cut the hay into hay sections by using a grass guillotine, and then feed it. Gramineous forages are generally cut into 2 cm and 1 cm for sheep and legumes respectively. The proportion of leguminous hay fed to sheep is generally no more than 30% of the diet, and gramineous forage is free to feed.

Silage utilization technology

1. Harvest time: perennial legume grasses such as alfalfa and Astragalus adsurgens are generally not the main raw materials for individual variety silage, but they should still be preserved by silage in some cases. The most suitable harvest time for legume silage is the early flowering stage, which should not exceed the full flowering stage at the latest, and the crude protein content is higher in the early flowering stage. although the crude protein content decreased and the crude fiber content increased in the full flowering stage, the forage yield was the highest. after the crude fiber was decomposed by silage fermentation, its palatability and utilization rate were still very high. Sudan grass and its hybrids, forage sorghum and barnyard should be harvested from early booting to early flowering stage and at the latest to milk stage.

2. Silage method: leguminous forage is generally not suitable for individual silage, but can be mixed with Sudan grass and its hybrids, forage sorghum and barnyard to make mixed silage. The mixed ratio is leguminous forage: Gramineae forage is 30-40%-60-70%. Low moisture silage can also be carried out, that is, the water content of the raw material is reduced to 450.55% for silage. Sudan grass and its hybrids, forage sorghum and barnyard can be made into silage separately. The commonly used silage facilities are silage cellar, plastic bag silage and stretch film silage.

3. Feeding method

The daily feed quantity of ① sheep and goats is 4 5kg and 3 4kg respectively.

When feeding pregnant sheep with ② silage, it should not be fed 20-30 days before and after delivery, and frozen silage should not be fed to avoid miscarriage.

③ silage can not be fed to livestock alone, but should be mixed with other feed according to a certain proportion, generally no more than 50% of sheep diet.

④ is taken out every day according to the actual feed intake of sheep and taken as soon as possible to minimize the storage time and avoid secondary fermentation. The silage left uneaten by livestock in the trough should be removed in time and cannot be put back into the silage container.
