What should we pay attention to when raising young sheep?
Breeding sheep refers to the young sheep from weaning to the first mating. 3-4 months after weaning, the growth and development is fast, the intensity of weight gain is high, and the feeding conditions are high. After 8 months of age, the growth and development intensity of sheep decreased gradually.
The key points of feeding and management in the early stage of breeding in this period, especially in the newly weaned lambs, the growth and development is fast, the rumen volume is limited and the function is not perfect, and the utilization ability of roughage is poor. Therefore, during this period, the diet of sheep should be based on concentrate, and be able to supply high-quality hay and green succulent feed, and the crude fiber content of the diet should not exceed 15% and 20%.
The main points of feeding and management in the later stage of breeding during this period, the rumen function of sheep was basically perfect, and a large number of forage grass, silage and microsilage straw could be eaten. The proportion of roughage in the diet can be increased to 25%, 30%, and concentrate or high-quality silage hay must also be added.
The management of sheep in the breeding period directly affects the early reproduction of sheep, which must be paid attention to. The female lamb weighs 40 kg at 6 months and can be mated at the age of 8 months. Therefore, in order to make 80% of the female lambs participate in the mating of the same year, the feeding during the breeding period is very important.

The following antibiotics are available for treatment: lincomycin, 11 mg per kilogram of body weight per day, oxytetracycline, 25 mg per kilogram of body weight per day, and ampicillin 15 mg per kilogram of body weight daily for 5 days. If the medication does not improve for three consecutive days, another antibiotic should be used. Complete recovery takes 3 ~

Cattle feeding distiller's grains has many advantages.
Distiller's grains is the direct leftover in the process of brewing, it not only contains a certain proportion of grain (can save the concentrate for feeding cattle), but also contains rich crude protein, which is about 2-3 times higher than that of corn. at the same time, it also contains a variety of trace elements, vitamins, yeasts and so on, in which lysine, methionine and tryptophan are also very high, which can not be provided by crop straw. Compared with crop straw, the coarse composition of distiller's grains is also higher. Because the distiller's grains are all formed by fermentation and high temperature cooking, so it is thick.
