Effects of TMR Feeding of Different Nutrition Level for Growing Dairy Goats
The objective of this experiment was to evaluate growth performance in dairy goats (Saanen) fed total mixed ration (TMR) of different nutrition levels. Twenty four growing female goats of 8 months of age were randomly assigned to one of four TMRs; low energy-low crude protein (CP) TMR (control), high energy-low CP TMR (T1), low energy-high CP TMR (T3) and high energy-high CP TMR (T4). The content of total digestible nutrients (TON) and CP in the control diet were 64% and 12%. The TON content of the high energy TMR was 72% and the CP content of the high CP TMR was 14%. Feed intakes were 1,194g, 1,060g and 1,124g for T1, T2 and T3, respectively, being higher than control (1,039g). Average daily gain was also numerically higher for T1 (170.2g), T2 (114.5g) and T3 (154.9g) than for control (109.0g). The difference of average daily gain between T1 and control was statistically significant (P<0.05). Although there were no significant differences in feed intake (% of body weight) between treatments, feed conversion ratios showed different responses; T1 (7.01) and T3 (7.26) being higher than T2 (9.26) and control (9.53). The increases of heart girth were 11.8cm, 10.0cm and 11.4cm for T1, T2 and T3, respectively, being higher than control (8.1cm).
