Feeding techniques of Boer Goat

Recently, Boer goats have become the highlight of the breeding industry, and many farmers do not hesitate to spend a lot of money to buy Boer goats. As a matter of fact, this practice is not scientific and cost-effective enough. If you are not careful, you may be deceived. Here, let me tell you a cost-effective way.

If the funds are limited, you can only buy 3 purebred Boer goats, and use this kind of sheep to mate with local female goats. After conception, the male lambs of the first generation of Boer goats can only be raised as meat goats and fattened after castration. When the ewes of the first generation of Boer goats grow up, they will mate with another purebred ram and give birth to the second generation of Boer goats. Note: a generation of Boer goats are in estrus, do not use its "father" to avoid inbreeding. The second generation of Boer goat males are still unable to breed, and when the second generation female lambs grow up and mate with other purebred Boer goats, they can give birth to three generations of Boer goats. At this time, it has been identified that the ram and ewe with good performance can be used as breeding sheep, and if there are conditions, they can be further improved. Generally speaking, using this method to breed Boer goats, a large number of purebred Boer goats can be bred in 2-3 years, which is much cheaper and more cost-effective than directly buying Boer goats. A purebred ram can breed at least 500 ewes in a year, and tens of thousands of ewes can be mated with artificial insemination. Using this method to breed Boer goats must also pay attention to: ewes used for mating must be larger, small "native goats" are not allowed, small goats are very likely to cause dystocia after breeding with purebred sheep, and the lives of female offspring are in danger. Only large ewes can mate with purebred rams, which should be borne in mind.

Goats raised in rural areas weigh only 15 kg at the age of 12 months, while native sheep weigh about 25 kg at the age of 12 months. The reasons for the slow growth rate: first, inbreeding, physical degradation; second, do not pay attention to deworming, consuming a lot of nutrition; third, there is no scientific ingredients, can not meet the nutritional needs of sheep growth and development. If you want to make mutton sheep grow fast, you must master the following techniques:

The main results are as follows: 1. There is no meat sheep breed in our country, only by introducing foreign breeds with large size and good meat production performance, domestic improved breeds and local native sheep by artificial insemination to obtain hybrid commercial mutton sheep. For example, Boer goat crosses with local goat. The hybrid sheep showed strong heterosis, fast growth, strong disease resistance and high feed conversion rate.

2. Parasites should be expelled before sheep are fattened. Levamisole, a highly effective deworming drug, is dissolved in warm water according to 8 mg per kg body weight, and 5% aqueous solution is prepared for intramuscular injection, which can dispel a variety of roundworms and nematodes in sheep; thio-dichlorophenol, 80 mg per kg body weight, add a little flour to 250 ml of water, and fishy administration can dispel sheep liver trematodes and tapeworms; after shearing, 1% trichlorfon solution is used to eliminate external parasites. This avoids the extra nutritional loss of sheep and ensures the fattening effect.

3. Scientific ingredients now introduce the more practical feed formula as follows: corn meal 45%, rice bran 20%, bean cake 10%, cottonseed cake 15%, wheat 12%, bean cake 30%, salt 1%, fish crushing%. Lambs are fed 150 grams a day after weaning. With the increase of age, the daily feeding amount can be increased to 200 grams, 400 grams at 6 months and 500 grams at 7-8 months old.

4. The commonly used additives are as follows: (1) Sheep fertilizer compound feed additive. It is composed of trace elements, rumen metabolic regulators, growth promoters and so on. It is suitable for fattening sheep in the same year and eliminating rams, old and weak adult sheep. The grazing sheep were fattened with concentrate and mixture for 90 days, and the average daily gain was 137g, which could significantly improve the fattening effect and economic benefit, shorten the fattening period and save feed. (2) monensin sodium, also known as ruminin. The function is to control and improve the rumen fermentation efficiency, so as to improve the weight gain rate and feed conversion rate. The dosage is 25-30 mg per kilogram of diet. (3) olaquindox, also known as Kuaiyuling, is a synthetic antibacterial agent. It can promote protein assimilation by adding 50 mg per kg diet. (4) urea. The aim is to supplement the lack of protein in the feed and mix it in the concentrate at 1.5% Mel 2%. The daily feeding amount accounts for 0.02% of the body weight of sheep, that is, the daily feeding amount of adult ewes is 10-15 grams, and that of young sheep over 6 months old is 6-8 grams. The first feeding amount can only be fed according to a specified amount of 1 gram 10, gradually increasing. It can be added to the specified amount after 10 days. In order to prevent urea poisoning, urea can not be fed alone, nor soluble in water, do not drink water within half an hour after feeding. Little or no feeding to sick and weak sheep, in case poisoned sheep are found, they can be saved by filling them with 0.5% vinegar 200-500 ml or 1-2 kg yoghurt.

5. Epidemic prevention and control of common diseases in mutton sheep production are: lamb dysentery, the symptoms are loss of appetite, diarrhea, stench of feces, lying on the ground can not afford. Prevention and treatment: 0.15-0.2 grams of mycin were given to sheep 12 hours after birth, and dysentery was given to diseased lambs, 0.01 grams per kg body weight. Enterotoxemia is characterized by rapid diarrhea, lying on the ground, dyspnea, white taste at the mouth and head back. During prevention and treatment, sheep fast epidemic and enterotoxic blood vaccine were injected regularly, and sick sheep were injected with penicillin 80-1.2 million units intramuscularly. In addition, prevention and treatment of rumen dyspnea and pneumonia should also be strengthened.
