粗饲料在反刍动物消化道被吸收利用遵循的一个原则是,养分所含能量的利用率主要取决于粗饲料的质量。劣质粗饲料同优质粗饲料相比,对消化道的刺激作用更加明显,促进消化道器官质量的增加,使这些器官的活动量增加,从而加大了奶牛的维持... 粗饲料在反刍动物消化道被吸收利用遵循的一个原则是,养分所含能量的利用率主要取决于粗饲料的质量。劣质粗饲料同优质粗饲料相比,对消化道的刺激作用更加明显,促进消化道器官质量的增加,使这些器官的活动量增加,从而加大了奶牛的维持需要。 展开更多

NDF消化率在奶牛日粮中扮演着十分重要的角色。很多困扰着牧场的营养问题都与粗饲料质量、日粮NDF消化率有着密不可分的关系。通过测定牛粪NDF含量可以在一定程度上反应日粮NDF的消化情况,下面谈一谈日粮NDF消化率及牛粪NDF那些事。

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
