Breeding techniques of Nubi Goat

Nubi goat is a meat and milk type, also known as Nubian goat, because it is native to the Nubian area in the upper reaches of the Nile in Egypt, it has good heat resistance and poor adaptability to cold and humid climate. it is used to improve the meat performance and reproductive performance of local goats. This breed has been introduced in Guangxi, Sichuan and other places in our country. Let's take a look at the breeding techniques of Nubi goats.

Feeding and Management of Nuby Goat

The main results are as follows: 1. Breeding methods: Nubi goats are often raised in captivity or bolted in hilly areas, mainly in mountain areas, captive and tethered by most farmers, and there are leaking sheep beds, sinks, food troughs and other facilities in the sheep house.

2. Feed configuration: the forage grass of Nubi goat is mainly wild forage grass, leaf branches, vines, farmers' manuscripts and artificially planted forage grass, and the concentrate feed is mainly corn, wheat and wheat bran, and appropriate feed additives are added.

3. Disease prevention: Nubi goats are vaccinated twice a year, and seasonal deworming can ensure the healthy development of Nubi goats.

Multi-lamb feeding of Nuppi Goats

1. Lamb foster care: if an ewe gives birth to a prolific lamb (or ewe dies accidentally after birth), a litter of lambs with more lambs can be divided into a portion of the ewes with fewer lambs. In order to ensure the success of foster care, it is generally required that the delivery dates of the two ewes differ within 3 to 5 days, and there is little difference in individual weight between the two litters of lambs. In addition, ewes have a sensitive sense of smell and refuse to breast-feed in order to prevent ewes from sniffing out the smell of farmed lambs. Generally, foster lambs are recommended to be carried out at night. Before foster care, two litters of lambs are sprayed with drugs with the same smell, such as stinky potion or alcohol, or smeared on the milk and urine of the foster ewes, and then the two litters of lambs are fed together for 30 minutes, so that the farmed ewes can not tell the truth from the false. In order to achieve the purpose of foster care.

2. Breastfeeding in batches: if the suckling lamb exceeds the number of nipples of the ewe, the lamb can be divided into two groups and breast-fed in turn. When adopting the method of breastfeeding in batches, the feeding and management of lactating ewes must be strengthened to ensure the upper-middle nutrition level of ewes, so that ewes have enough milk for lambs to lactation. The lambs in groups should be rationally distributed according to their size and strength, and at the same time, do a good job in the early feeding of suckling lambs, so as to reduce the lactation burden of ewes as much as possible and ensure the balanced development of the whole litter of lambs.

Prevention of dystocia in Nubi Goat

1. Prevent premature mating: from a physiological point of view, ewes generally reach sexual maturity at the age of 5-6 months, have the ability to reproduce, and have the first estrus, but at this time the ewes are not yet mature. In this way, mating will curb its growth and development, naturally its pregnancy will also be seriously affected, the consequence of this effect is to increase the occurrence of dystocia. Therefore, for goats, the time for the first mating of ewes should be chosen when the sheep has reached maturity, so that not only the health of ewes will not be affected, but also strong young sheep can be obtained.

2. The principle of body size selection: in the cases of dystocia, about 50% are related to the excessive size of the fetus, and most of them are related to the use of large breed rams, especially when the ewes are not yet mature, the incidence of dystocia is higher. Therefore, we should adhere to the correct principle of all-in-one selection. The correct body size selection principle should be at that time: large size, large size, medium size, small size, never large size and small size. The result of large matching with small often leads to too large fetus and increases the occurrence of dystocia, and the consequence of premature mating is more serious.

3. Management of pregnancy: goat dystocia, in addition to the above two factors, poor feeding and management during pregnancy is also an important factor. Malnutrition in pregnant goats is one of the causes of dystocia. Obese or malnourished ewes during pregnancy can lead to lack of fertility and induce dystocia. At the same time, exercise is indispensable to pregnant ewes, and quite a few dystocia ewes are related to the lack of exercise during pregnancy. Lack of exercise in pregnant sheep may not only lead to fetal malposition, but also lead to insufficient productivity, both of which are the direct causes of dystocia. For ewes, reasonable exercise should be moderate and moderate. It is usually 2 hours a day.

Breeding advantages of Nuppi Goat

1. Tall and tall: the general weight of adult rams of Nubi goats can reach more than 300 jin, and adult ewes can reach more than 200 jin. At the age of 2 months, the weaning weight of rams and ewes is 28.16 kg and 21.20 kg, which is 50% higher than that of other domestic breeds.

2. Strong fecundity: the initial mating time of Nubi goat is 6-9 months old, the mating time of ewe is 5-7 months old, the lactation period is 70 days, the survival rate of lamb is 96.98%, the lambing rate is 2.65, and the number of births is 2 times a year.

3. High meat production rate: the slaughter rates of adult rams and ewes of Nubi goats were 51.98% and 49.20% respectively, and the net meat percentage were 40.14% and 37.93%, respectively.

4. Strong adaptability: Nuby goat has good adaptability and good production capacity, and the effect of improving transferred ewe is remarkable, among which the effect of improving Jianyang big-ear sheep is the most significant.
