ABSTRACT

Consistent dry matter and nutrient intake is very important in attaining good milk quality and high milk production. Hence, there is a need for a ration that will overcome the variable supply and quality of feed. Total Mixed Ration (TMR) is a form of complete feed formulation that provides consistent supply of nutrients to sustain high milk production. This study aims to compare the yield and quality of milk produced by Holstein-Sahiwal cows fed with either HD-TMR or LD-TMR. Physical and chemical properties of the two TMR formulations were analysed. Its effect on the yield and quality of milk were also examined. Results of the TMR analysis established the contrasting physical and chemical composition of the two TMR formulations. Milk quality analysis showed significant differences in the fat contents of the two groups of cows fed the two types of TMR. Milk from cows fed with HD-TMR had lower fat compared with the cows fed the LD-TMR. Cows fed high density TMR produced more milk during the first 90 days of lactation compared with those cows fed LD-TMR. All cows have the same body condition (BCS = 3) after the 90- day feeding period.
