Twenty lactating cows of two to five parity having an average live weight of 290.00 to 330.00 kg and an average milk production of 4.54 kg/head/day to 4.66 kg/head/day were selected from the Central Cattle breeding St... Twenty lactating cows of two to five parity having an average live weight of 290.00 to 330.00 kg and an average milk production of 4.54 kg/head/day to 4.66 kg/head/day were selected from the Central Cattle breeding Station and Dairy Farm. The four dietary treatment were: SlooTo (Straw 100: Triticale 0 as control); $5oT5o (Straw 50: Triticale 50); $25T75 (Straw 25: Triticale 75) and SoTloo (Straw 0: Triticale 100). It was observed that the roughage dry matter intake (DMI) (2.61 ~ 0.07 kg) in percent live weight was significantly (P 〈 0.05) higher in $25T75 and the lowest (1.76 ~ 0.018 kg) in the control group (SlooTo) and the differences were significant among the dietary treatments except $5oT5o and SoTloo. The total DMI was significantly (P 〈 0.05) higher in SoT^oo (13.36 i 0.13 kg) followed by $25T75, $5oT5o and SlooTo, respectively. The digestibility of crude protein (CP) was slightly higher in $25T75 (75.48 ~ 0.96) compared to SoTtoo (75.31 ~ 1.45) and the difference was non-significant (P 〉 0.05). Milk production was significantly (P 〈 0.05) the highest in $5oT5o and the lowest in SlooTo followed by SoTloo, $25T75, respectively. The percent increased in milk yield was also the highest in $5oT5o (67.68%) and the lowest in SlooTo (28.85%). The 4% fat corrected milk was also significantly (P 〈 0.05) higher in $5oT5o followed by SoTloo, $25T75 and SlooTo, respectively. Therefore, it can be concluded that triticale and straw at a ratio of 50:50 may be fed for better production performance of dairy cows. 展开更多
