Abstract: The work on the crossbreeding of local cows with Murrah bulls was started in 1971 in Sichuan and to 1985 about 55,000 crossbred were produced. The first filial generations are generally recognized as being superior to local breeds in size, working ability, meat production and milk producing ability. It has been found that the milk in 1st lactation of F₁ female amounts to 1096.65 kg and contains 8.5% milk fat, which corresponds to 1836.96 kg of standardized milk, but that a local cow only 441.41 kg of milk and with 9.57% of milk fat, which corresponds to 810.16 kg of standardized milk. In the 1st lactation the former produces 127% more than the latter. Therefore, buffaloes are a potential genetic resource, and the crossbreeding scheme may be suggested as an efficient way of improving the indigenous buffaloes for milk purpose.
