Breeding and Management techniques of Black Goat

When ordinary people raise black goats, they cannot ignore the pregnant goats and manage them well. The smooth production of pregnant goats can save a lot of trouble and effectively improve the economic benefits, so breeders should strengthen the management of pregnant goats. Next, let's take a look at the management of pregnant black goats and the fattening techniques of sheep shelves.

Management of pregnant Black Goat

Farmers must be aware of the seasonal pregnancy characteristics of black goats and the matters needing attention. Teacher Liang Chunting of Weiyan Black Goat breeding Base said that seasonal changes have a significant impact on the reproductive capacity of black goats.

1. From March to May, ewes are in good body condition, normal estrus, normal follicular development and easy conception after a winter's feeding.

2. From June to August, the weather is hot and the temperature is high, and some ewes are often in estrus, such as wig, intermittent estrus and so on. In this season, the conception rate of ewes is not high, and the embryo mortality rate is high.

3. From September to October, ewes are normal in estrus and easy to conceive. Winter is relatively cold in the northern region, ewes often appear irregular estrous cycle, false estrus and other phenomena, especially the ewes who often drink cold water will appear reproductive dysfunction. At this time, we should pay attention to the living environment of ewes, keep warm in the shed, get enough light, and drink plenty of warm water. Ewes imported from other places should pay more attention to the impact of environmental changes on them.

Fattening Management Technology of Black Goat frame Sheep

To raise black goats well, it is necessary to understand the fattening of shelf goats. Teacher Liang Chunting shared the fattening points of black goats with farmers:

1. Select taller black goats for fattening, and thoroughly deworming black goats before entering the fattening pen. There are many drugs for deworming black goats, such as levamisole, trichlorfon, apomidine and so on. Deworming is generally required to be carried out on an empty stomach in black sheep, which can achieve better results. When deworming with levamisole, the oral dose is 8 mg / kg body weight, when "Chong Kexing" is used, the oral dose is 100 mg / kg body weight, and the hypodermic dose of injection is 0.2 mg / kg. 3 days after deworming, sheep should be treated for stomach-strengthening, and artificial salt is commonly used as stomach-strengthening medicine.

2. The fattening methods of black goat shelf sheep mainly include distiller's grains fattening method, silage fattening method, ammoniated straw fattening method and high-energy diet intensity fattening method.

① distiller's grains fattening method: distiller's grains, bean curd dregs and beet dregs are all good feeds for fattening sheep, and wine trough fattening is a traditional method for fattening mutton sheep in China. Distiller's grains is a by-product of brewing industry, which is rich in yeast, glycerin, alanine, cellulose, ash and B vitamins. Therefore, distiller's grains is a good feed for mutton sheep. At the beginning, because the black goat did not like to eat distiller's grains, it was given only a little, mainly hay and coarse materials. Half a month later, gradually increase distiller's grains, reduce hay feed, to the middle of fattening can be matched with a small amount of concentrate and palatable feed to ensure a good appetite. When feeding lees, be sure to feed hay and silage straw first, and finally feed concentrate, and drink water 1 hour after feeding. Fattening sheep are required to feed an appropriate amount of concentrate. In addition, 0.002%-0.003% monensin and 0.5% sodium bicarbonate are added. Vitamin An and salt are better at the same time.

② silage feeding method: silage corn and fresh grass is one of the good methods for fattening mutton sheep. The digestibility of high quality silage fresh grass is very high, and the dry matter digestibility can reach 70%. When silage corn is used to feed mutton sheep, a better daily gain effect can also be obtained. With the increase of daily concentrate amount, the feed intake of silage corn decreased, although the daily gain increased, but the daily concentrate consumption also increased significantly. For the mutton sheep that only ate silage corn, the proper addition of a small amount of urea to the diet was beneficial to weight gain. When feeding silage corn, it is required from less to more, and then increase the feeding amount after lambs are accustomed to it, while adding 2-10 grams of sodium bisulfate to reduce the harm of organic acids.

③ ammoniated straw fattening method: ammoniating crop straw can improve the nutritional value of straw and improve the palatability and digestibility of feed. Allowing black goats to feed freely and adding appropriate amount of concentrate can achieve the purpose of gaining weight of meat goats, but because it is a feeding mode with low concentrate and high coarse feed and a long fattening time, it is not suitable for the scale feeding mode of fast turnover and early fattening. For heavy shelf sheep, short-term rapid fattening can be achieved if ammoniated straw is selected as the basic coarse material, proper amount of green coarse material and high-quality hay are added, and the proportion of concentrate is increased appropriately. The proportion of concentrate is: corn 65.9%, bean cake 9.3%, bone meal 1%, shell powder 2.5%, mineral and vitamin additive 0.5%, salt 0.8%. High-energy diet intensity fattening of black goats: this is a fattening method with high concentrate and low roughage. For shelf goats weighing 60 kg and aged 1.5 to 3 years, the proportion of concentrate in the diet should not be less than 70% of the concentrate for 15 days or a month after the transition period to adapt the black goats.
