ABSTRACT

         The experiment was designed in incidental conjugation method for 20 cross-bred cows HF (Holstein Friesian) with the target of comparing the effects between fermented total mixed ration (FTMR) food rationand the traditional feeding method on milk production. Maize stem, rice bran, cornmeal, groundnut oil cake, sugarcane molasses, beverage residue, cassava residue and concentrate have been used in the experiment. Milk production has been monitored individually every day. Milk quality (dry matter, fat, protein and lactose) has been analyzed with 1 sample/cow by Funke Gerber Lactostar 3510-123303 machine. The results have been shown. The costfor feed (each kg of milk) force sapplied with FTMR and the traditional feeding method considerably reduced (4734 VND in FTMR and 5381 VND in the traditional method). Indicators on feed quantities, milk capacity and quality show no difference between experimented samples and counter samples. Conclude, FTMR can be popularly applied in reality of cow feeding to help peasants to make use of agricultural raw materials in the region and food can be preserved in long time. This method also actively assists us to prepare food source for cows in dry season without any breeding efficiency.
