Lamb can be divided into lambs larger than 12 months of age and lambs less than 12 months old by age. Among them, lambs of 4-6 months of age are also called fat lambs. Due to the fact that fat lamb meat is more tender and lighter than adult lamb, so with the continuous improvement of people’s living standards in recent years, fat lamb meat has become popular among consumers and the demand has been increasing.
Fat lamb production has the following characteristics:
One is that lambs grow fast, have high feed returns, and have low production costs. The 1-month-old lambs had the fastest weight gain, and their feed remuneration was 3:1-4:1. The feed ratio of the adult sheep was 6:1-8:1, and nearly half of the feed was saved.
The second is that lambs were born that year, fattened in the same year, slaughtered that year, can increase the slaughter rate of the lamb, and can shorten the production cycle, the economic benefits are very obvious.
The third is to engage in lamb production as an effective measure to adapt to the seasonal changes in forage grass, which can reduce the weight loss of the sheep during the weedy period.
Fourth, the lamb meat market has a large demand, good prices, and high prices. In some places, it is 1/3-1/2 higher than the adult lamb price, and lambskin is of good quality and high in price. Due to the best economic benefits and social benefits produced by fat lambs, countries all over the world are actively researching and vigorously developing fat lamb production.
In the production of fat lambs, methods of intensive, industrialized, and large-scale feeding can be implemented. In the production, advanced production technologies can be fully utilized and practical experience for many years can be taken.
First, extensive use of modern breeding techniques
Sheep are single fetuses, and only one lamb is born per child. Propagation according to traditional methods can not meet people's needs for lamb production. Modern breeding techniques are widely used in fat lamb production. Such as adjusting the light to promote estrus early estrus, early mating, early weaning, induced childbirth, concentrated intensity fattening and other measures to better shorten the non-breeding period of the sheep, engage in one-year second or third child breeding. In particular, the use of estrus technology for the same period, so that the ewes at the same time estrus, unified breeding, can make large quantities of mutton production, so that a balanced listing, supply throughout the year.
Second, the early weaning of lamb
Postpartum lambs were weaned early, then dewormed and forced to grow for 2 to 3 months. Minimize activities and light during the fattening period. There are two ways for lambs to be weaned early. a. Weaning at 3–4 days of age and transfer to dry feeding period; b. Lambs were weaned 45–50 days after birth and transferred to dry feeding period. Because colostrum is rich in protein, fat, minerals and vitamins, especially magnesium ions and various antibodies, it has a special effect on promoting meconium excretion and enhancing disease resistance. Therefore, colostrum as the key to fattening The stage is essential.
Third, the use of artificial milk to raise lambs
IV. Feeding of fat lambs
After lambs were weaned for 56 days, each sheep was fed 3-5 kg ​​of green grass and 0.5 kg of concentrate. 20 days after weaning, 2.5 kg of the mixture (80% of hay powder and 20% of concentrate) were fed on each sheep day. The live weight of fat lambs was increased from 37.4 kg to 47.2 kg, and the average daily weight gain was 173 g. One kilogram consumes 8.2 kilograms of feed units.
Hungary uses large, double-layered, ground-floor hens to fatten lambs that can accommodate 3,000 to 5,000 lambs per house. The upper layer has a seam to facilitate the dropping of the droppings. A scraper conveyor is provided to transport the pelleted feed and a long-flowing drinking fountain. The lower deck is equipped with a scraper-type cleaning machine. Lambs were weaned 60-120 days after birth, and after 76 days of fattening, the average daily weight gain reached 230 grams. After finishing the fat, the weight reached 34-40 kg and the slaughter rate was 47.6%. The Czech Republic used merino and crossbreeding sheep to intensively fatten lambs. After birth, lambs are usually weaned after 3 days, and are fed with artificial milk on the 4th day. After 18 days, artificial milk and artificially cultivated pastures or mixed semen are added to forage grasses. The animals are bred to 82 days of age and the lambs can weigh up to 32. -35 kg.
