What are the feeding standards for mutton sheep farming?

1. Lamb fattening feed formula

Corn 62%, wheat bran 12%, soybean meal 8%, cottonseed meal 12%, limestone powder 1.8%, calcium hydrogen phosphate 1.2%, urea 1%, salt 1%, premix 1%. This formula contains 18% protein and 12.94 MJ/kg sheep digestible energy.

2. Intensive fattening concentrate formula

Early stage 20 days: corn 46%, wheat bran 20%, cottonseed meal or rapeseed meal 30%, limestone powder 1%, calcium hydrogen phosphate 1%, salt 1%, premix 1%. This formula contains 18.5% protein and 12.78 MJ/kg sheep digestible energy.

Mid stage 20 days: corn 55%, wheat bran 16%, cottonseed meal or rapeseed meal 25%, limestone powder 1%, calcium hydrogen phosphate 1%, salt 1%, premix 1%. This formula contains 16.8% protein and 13.00 MJ/kg sheep digestible energy.

Late stage 20 days: corn 66%, wheat bran 10%, cottonseed meal or rapeseed meal 20%, limestone powder 1%, calcium hydrogen phosphate 1%, salt 1%, premix 1%. This formula contains 15% protein and 13.20 MJ/kg sheep digestible energy.

The feeding standards for farming mutton sheep are formulated according to the nutrient requirements of Boer goats. They are the basis for guiding the feeding of mutton sheep. In production practice, the response of mutton sheep after being fed a Boer goat diet based on the feeding standard should also be observed at any time. Necessary corrections should be made. Theoretically, the feeding standard for mutton sheep consists of two parts: maintenance feeding and production feeding.

Maintenance feeding for mutton sheep is the nutrition required for mutton sheep to maintain unchanged body weight, good health, and a zero balance of various nutrients, without producing any product. The nutritional requirements for maintenance feeding vary with body weight, beef cattle, and management methods. The greater the body weight, the greater the requirement, and the maintenance requirement under housed feeding methods is lower than that under grazing feeding.

The nutrient requirements of Boer goats also differ significantly with age, whether pregnant or not, different stages of lactation, dry period, and other factors, so when specifically applying the feeding standard, necessary corrections and supplements should be made according to the specific conditions of the mutton sheep.
