Effects of different diets on milk yield and quality of lactating buffaloes: maize versus sorghum silage
Sixteen pluriparous lactating buffaloes were divided in two groups homogeneous for parity, lactation stage, milk yield and weight. The diets assigned to two groups, based on maize silage (M group) and sorghum silage (S group), had the same energy-protein level (0.90 Milk FU/kg DM and 155 g/kg DM of...

| Summary: | Sixteen pluriparous lactating buffaloes were divided in two groups homogeneous for parity, lactation stage, milk yield and weight. The diets assigned to two groups, based on maize silage (M group) and sorghum silage (S group), had the same energy-protein level (0.90 Milk FU/kg DM and 155 g/kg DM of crude protein). Five records of milk yield and quality during lactation were carried out. The physical-chemical characteristics (pH, fat, protein, lactose and urea), somatic cell count, coagulation properties and nutritional parameters (cholesterol, alfa tocopherol, 13 cis and trans retinol and 13 cis/trans retinol ratio) were analysed. Statistical analysis was performed using a factorial model. The average daily milk yield during experimental period was similar: 9.29 and 9.55 kg respectively in M and S groups. Fat and protein content were not different, while the urea content was significantly different varying from 39.13 mg/dl in M group to 45.55 mg/dl in S group. The coagulation properties, the estimated Mozzarella yield, somatic cell count and the nutritional parameters analysed were not different between the two groups. These results indicate that the sorghum silage diet utilised did not affect the milk yield and quality, then it could be adopted in lactating buffaloes. |
