What kind of crops should be fed when raising cattle and sheep? Which have high nutritional value?

In rural areas, cattle, sheep and chickens are the most common kinds of poultry raised by farmers, but because of their large feed intake, and many of them are mainly forage grass, so if you want to raise powerful sheep, you need to understand the feed collocation. When raising cattle and sheep, what crops should be fed? Which have high nutritional value?

Summer green feed

To solve the problem of green fodder in summer, it is best to plant Yugu, followed by Sudan grass, Gaodan grass and so on. Yugu has strong resistance to drought, high temperature and regeneration. It can be mowed 3 or 4 times a year, and the yield of fresh grass can reach more than 5000 kg per mu.

1. Yugu

Yugu is a drought-resistant, heat-resistant and saline-alkali-tolerant crop that is not resistant to waterlogging. The row spacing of strip sowing is 60-65cm and the plant spacing is 20-30cm. It can also be sown in square holes where the row spacing is 70cm, leaving 2-3 basic seedlings in each hole. Yugu is very sensitive to fertilizer. After setting the seedlings, the chemical fertilizer with nitrogen content of 45 kg per hectare is applied, and in the land with medium fertility, the grain can be harvested about 3000kg per hectare.

The grain protein content of most varieties is higher than that of wheat, rice, corn and sorghum. It is 8.3-20.9%, with an average of 16%.

The seeds of Imperial Valley are used for grain. Dry Imperial Valley is ground into powder or wet into paste to make cakes or bread and other forms of cakes. Its stalks are used as livestock feed, fuel or building materials for cottages. In developed countries and regions, grains are mainly used as feed or fillers for poultry and livestock.

2. Sudan grass

Grazing and utilization: Sudan grassland can be grazed and fed by cattle, sheep, pigs, horses and other livestock without fear of swelling disease. Generally, the first grazing is at the early jointing stage, the second is at the booting stage, the third is at the heading stage, and the fourth is before or after the frost.

Green forage: Sudan grass can be cut by stages as a high-quality green and succulent feed for horses, cattle, sheep, pigs, rabbits and fish. Generally, it can be cut for the first time when the plant height is 50-70 cm, and then once every 20-30 days. If the young fresh grass of Sudan grass is fed to pigs, it can account for 1x3-1 of fresh grass, which can be beaten or crushed. Cattle should be fed with 30-40kg of fresh grass every day; sheep and rabbits can be fed whole or cut short; when feeding fish, the fresh grass can be crushed and fed, the effect is better.

3. High single grass

The percentage of crude protein and crude fat in fresh weight of Gaodan grass is 2.49% and 0.6% respectively, which is a good feed for cattle, horse, sheep and fishing. It can be used for silage or silage, or it can be made into hay.

Gaodan grass is a temperature-loving plant, which is not resistant to drought at seedling stage, and the suitable growth temperature is 24 ℃ ~ 33 ℃. It has strong disease resistance and strong regeneration ability, and can cut 3-4 crops a year. Hay contains more than 15% crude protein and high sugar content, so it is suitable for silage. All kinds of livestock and poultry like to eat, and the grass supply period is from May to October.

Hay feed in winter and spring

1. Silage

To solve the hay in winter and spring, it is best to choose silage. The silage is compacted and sealed, resulting in lack of oxygen inside. After lactic acid bacteria fermentation decomposes sugars, the carbon dioxide produced further removes the air, and the lactic acid secreted makes the feed weakly acidic (pH value 3.5-4.2), which can effectively inhibit the growth of other microorganisms. Finally, the lactic acid bacteria were also inhibited by the lactic acid produced by themselves, the fermentation process stopped and the feed entered stable storage. But at this time, the loss of nutrients such as sugar in the raw materials is not great.

The main nutritional quality of high-quality silage is similar to that of its silage raw materials, which is mainly manifested in that the silage has good palatability, and its ruminant feed intake, organic matter digestibility and effective energy value are similar to those of silage raw materials. The vitamin content and energy level of silage are higher, and the nutritional quality is better. Silage is the basic feed for herbivores, and it is generally appropriate to feed no more than 30% of the diet, 50% of the diet.

2. Barnyard valley

Its plant height can reach more than 2 meters, and the grass quality is better than any kind of gramineous forage crop. The crude protein content of hay reaches 6.66% to 8.70%, which is better than that of millet. The yield of hay per mu can reach more than 1000 kg, which is more than twice that of millet. The seed can reach more than 350kg. It is a rare supplementary feed for cattle and sheep.

Barnyardgrass is an excellent annual forage grass of Gramineae. It has a well-developed whisker root system, erect stem, 1.9-2.1 m plant height, strong tillering ability, wide stripe leaves, 3 cm wide and 60-70 cm long. It has wide adaptability, strong resistance, late maturity, growth period of about 135 days, abundant leaves and good palatability. it is suitable for feeding cattle, sheep and geese. It can produce hay 1.5-2 tons / mu and seed yield 400-500 kg / mu once a year. Spring sowing, one kilogram of seed per mu. It can be used for silage, silage and drying hay.
