Effects of feeding systems during late pregnancy and post-partum periods on feed intake and milk yield of 50 % Thai Native-Anglo Nubian crossbred does
The objective of this research was to study the effects of feeding systems on feed intake and milk yield of 50 % Thai Native-Anglo Nubian crossbred does. Twenty four does at 90 days of pregnancy werekept in individual pens and fed Napier grass (Pennisetum purpureum) ad libitum. They were alloted to...

Twenty four does at 90 days of pregnancy werekept in individual pens and fed Napier grass (Pennisetum purpureum) ad libitum. They were alloted to 3 groups of different feeding systems according to a completely randomized design: 1) no supplementedconcentrate during late pregnancy period but supplemented with 14 % crude protein (CP) concentrate ad libitum during post-partum period; 2) supplemented with 14% CP concentrate ad libitum both during latepregnancy and post-partum periods; and 3) as group 2 but the concentrate contained 18% CP. Feeding systems significantly (P<0.05) affected feed intake of Napier grass during late pregnancy period. Dry matter intake of Napier grass of group 1 (865.32 g/d or 62.27 g/BW0.75/d or 1.73 %BW) wassignificantly (P<0.05) higher than those of groups 2 and 3 (225.72; 310.58 g/d or 15.34; 21.12 g/BW0.75/d or 0.43; 0.60 %BW, respectively).
