First of all, food restriction methods and precautions should be based on achieving the best ratio of feed to meat. Lambs before 50 kg are not suitable for use, and after 50 kg, different feed intake limits can be set according to the variety.
Precautions for feeding restriction are as follows: lambs in the same column must be similar in weight, otherwise it will easily lead to the law of the jungle; There should be enough feed trough and lamb pen area so that lambs can eat feed at the same time (generally, the fattening feed trough for lambs weighing 60 ~ 100 kg needs to be 30 cm long); Excessive feeding restriction will prolong the selling age, so the building capacity of the lamb house should be corresponding; Feed formula should use high-quality raw materials; When food restriction is implemented, it is better to raise males and females separately; For feeding restriction, male lambs need more than female lambs, poor breeds need more than good breeds, and cool seasons need more than hot seasons. If you want to delay the sale, you can reduce the feeding amount by about 5%, but it should be noted that if the feeding restriction is too serious, the weight gain and meat exchange rate will become worse, and the lean meat rate will not necessarily increase.
Second, separate feeding of males and females If your lamb farm is large enough and easy to manage, you can separate feeding of males and females. Feeding male and female separately can make your lambs neat and consistent. More importantly, the nutritional requirements of castrated male lambs and female lambs are different. Different nutritional requirements can give castrated male lambs cheaper feed to achieve the purpose of reducing costs.
Third, the types of lambs should be fed as usual, and inferior feed or reduced intake should not be used. People who have this idea might as well not have lambs. Raising lambs is the locomotive of sheep farm. Feed quality and feeding amount directly affect reproductive performance, so it is unnecessary to lack two Jin. Otherwise, once the reproductive performance declines, the cost shared by each lamb will eventually increase, which will definitely outweigh the benefits.
