What are the advantages and disadvantages of lake sheep? What are the characteristics of different f

1. One of the advantages: the lake sheep has high fecundity, under the condition of good feed conditions, the female lake sheep can give birth to 2 3 litters a year, the number of lambs in a litter is 2 3, there are 4 5, the lambing rate is very high, higher than the Boer goat, second only to the small-tailed Han sheep. Advantage 2:

The growth rate is fast, the 6-month-old Hu sheep can weigh 60 catties, and the 10-month-old can exceed 90 catties, which is quite fast. Advantage three: strong adaptability, Hu sheep has the characteristics of high temperature resistance, high humidity resistance, and cold resistance, in the Jiangnan region, the temperature is 37 39 degrees Celsius, the relative humidity is more than 80% of the environment, Hu sheep can adapt.

In addition, it can be cultivated in the northwest alpine region, and it can still grow well. Advantage 4: Hu sheep not only has good meat quality, but also has a high meat yield.

The meat of Hu mutton is delicate and delicious, the taste is light, and the net meat rate is high. In terms of net meat rate, Hu sheep can reach it, which is higher than that of small-tailed Han sheep.

2. In the process of breeding, the most headache for farmers is the disease. At present, the most common diseases found in Hu sheep mainly include dry and thin disease, cold, diarrhea, rotten mouth disease, pneumonia and death disease. Therefore, farmers must have a basic understanding of these diseases and know how to prevent them.

Breeding lake sheep is not as good as breeding small-tailed Han sheep, although the resistance of lake sheep is faster than that of small-tailed Han sheep, but its disadvantages are.

Slow rise, low reproduction rate, low meat rate, in these aspects of the small-tailed Han sheep are better than the lake sheep, the benefit of the output value is also much higher than the lake sheep. Small-tailed Han lamb 600-900 yuan, adult ewe.

Lake mutton is of average quality.

Hu sheep belongs to the sheep breed, which has strong adaptability, fast growth, clever file or early maturity, high reproductive rate (year-round breeding), more meat, and average meat quality. However, lake sheep are easy to raise but not easy to sell. Hu sheep is one of the important livestock in the Taihu Plain, and it is a first-class protected local livestock and poultry breed in China.

The lake sheep has a medium physique, both male and female have no horns, a narrow head, and a raised nose bridge; Most of the ears are large and drooping, the neck is slender, the body is long, the back and waist are straight, and the abdomen is slightly drooping; tail oblate, tail tip upturned, limbs thin and high; The coat is all white, and the abdominal hair is coarse, thin and short, and has the characteristics of high temperature and high humidity resistance. Lake sheep generally give birth to 2 to 3 lambs in a litter.

Lake sheep

Hu sheep, a genus of bovine sheep, is a first-class protected local livestock and poultry breed in China. It is mainly produced in Jiaxing and Taihu Lake areas in Zhejiang. Lake sheep have a long history as a precious lambskin breed.

According to historical records, the breeding of lake sheep in Zhejiang began in 1126 AD. The formation of Hu sheep was the early northern immigrants who carried Mongolian sheep southward, and changed grazing to captivity under the condition of lack of natural pastures in the south.

The long-term feeding of Hu sheep has formed a stupid habit of "grass to open its mouth, and no grass to call". In the absence of external factors interference, hearing the whole flock of sheep to make a "bleating" filial piety cry, most of them are caused by hunger, and the grass should be fed in time. It is quiet at night, less disturbing, and has a large amount of grass (about 2 3 of the daily grass requirement).

Farmers who have been raising lake sheep for a long time have summed up the experience of "sheep should bark when there is a lack of grass during the day, and they will not grow fat when there is no grass at night".

The key step in feeding Hu sheep is mainly to choose the right feed, and then I will introduce to you the characteristics of different feed for Hu sheep.

Lake sheep concentrate feed

Lake sheep do not need to be fed concentrate feed. Farmers usually do not feed concentrate, generally in ram breeding, ewe pregnancy, lactation, lamb weaning and sheep when the body is thin to feed some concentrate, as supplementary feed.

The supplementary concentrate feed is mainly the seeds of the grass family and leguminous family, such as soybeans, barley, wheat, broad beans, etc., as well as processing by-products such as soybean cake, rapeseed cake and cottonseed cake, etc., the concentrate feed is rich in nutrition, protein, fat and vitamin content is higher, crude fiber content is less, and there is aromatic odor, palatability is better.

However, rapeseed cake and cottonseed cake are toxic, so we should pay attention to detoxification and dosage, and mix with other feeds.

Bran feed for lake sheep

Bran feed is the main by-product of cereal seed husk processing. Bran feed has high nutritional value, more fat and protein content, especially phosphorus and vitamin content is higher than cereals, and less calcium content.

Bran feed is loose in texture, large in size, and good palatability, but has a laxative effect, so pay attention when feeding. Fast-growing bran feed lambs, rams, and pregnant ewes should not be fed more. Bran feed, because it contains more fat, is stored for too long and is easy to deteriorate, so it should be stored in a dry and ventilated place.

Roughage for lake sheep

All crop straw such as straw, wheat straw, bean straw, corn stalk and seed husks, as well as various weeds, leaves, etc., can be used as roughage for Hu sheep.

These roughages are low in protein, fat and minerals, and their nutritional characteristics are coarse and hard, and they contain more crude fiber. However, Hu sheep have a strong ability to use roughage, and are more selective about the quality of wild grasses, and prefer short, short and delicate leguminous and grassy weeds.

Nutritional characteristics of green feed for lake sheep

1*** Lake sheep green feed has a lot of moisture content.

Generally, it is 60%-80%, and aquatic feed can reach 90%-95%.

2*** Lake sheep green feed nutrition is more comprehensive.

In terms of dry matter, the crude protein content generally accounts for l***j% to 2u%, and the content of lysine and histidine is more, and the essential amino acids are more comprehensive, so the protein quality is better.

Rich in vitamin content, containing a large amount of carotene and rich in thiamine, riboflavin, niacin and other U vitamins, as well as more vitamin E, vitamin C and vitamin Jing rock head K, etc., carotene contains about 50-80 mg per kilogram of jujube, higher than any other feed, containing all kinds of enzymes and hormone-like substances.

3*** Lake sheep green feed has good palatability.

High digestibility, green feed is tender, Hu sheep like to eat, can be fed directly after mowing; The crude fiber content accounts for about 18%-30% of the dry matter, and the nitrogen-free extract content is high, accounting for about 40%-50%, which is easy to digest and absorb.

When feeding, it is also necessary to ensure regularity, try to ensure that the feeding is fixed every day, and ensure the amount when feeding, which is twice a day. We should also pay attention not to feed the same feed for a long time, which will lead to insufficient nutrition, it is recommended that you can add a little salt to the feed or drinking water, which can effectively help the sheep digest food, and can also increase their desire to eat. The last point to mention is disease.

Especially now that summer is coming, it is easy to cause some infectious diseases and some toxic bacteria in summer. The healthy growth of Hu sheep in the later stage is inseparable from the breed with the growth rate. Here it is recommended that you can choose a breeding ram that grows faster, and it is best to have a more well-proportioned body shape.

I feel that there is no big difference between the breeding of Hu sheep and ordinary sheep, but Hu sheep need more careful care when raising, for example, the forage they eat is fresher, and they will choose some more tender grass to eat.

Lake sheep living habits.

Suitable for house feeding: The ancestors of Hu sheep were originally grazing Mongolian sheep, and they have migrated to Jiangsu and Zhejiang to be raised in captivity for more than 800 years. This characteristic of the lake sheep is conducive to the factory production of fat lambs.

Goat habits.

Goats are brave and lively, agile and witty, like to climb, good at loaming, are lively small ruminants, and love gladiatorial fights.

Lake sheep breeding. The breeding season of Hu sheep is generally arranged in April and May in spring, and lambs are born in September and October in autumn, and two litters a year. However, some sheep can also appropriately adjust the breeding season, arrange breeding in September and November, and lamb in February and April of the following year, so as to achieve "three litters in two years". However, the sheep produced in autumn and spring should not be retained, and they are only allowed to be used for meat sheep production.
