Utilization of rice straw for feeding ruminants: 4economic and nutritional study of corn stalks and green rice straw silages in partial replacement of berseem in winter feeding of lactating buffaloes
Abstract: Five scenarios (rations) were formulated by computer to evaluate com stalk silage (CSS) and rice straw silage (RSS) when they replaced part of berseem in winter rations for lactating buffaloes. The scenarios were used each type of silage by two levels to compare with control ration. Three scenarios out of five were selected to apply in vivo through a comparative feeding trial at Mehallet Mousa Research Station. Five lactating buffaloes averaged 550 kg LBW at the 2nd to 5th of its lactation seasons and after 8 weeks of calving were used through Swing-over design. The experimental rations were: control ration (CR) represented traditional winter ration: 34.0% concentrate feed mixture CFM) + 49.0% berseem (B) + 17.0% rice straw (RS): TR1 and TR2 were 34.0% CFM + 34.0% Berseem + 32% CSS and 34.0% CFM + 34.0% Berseem + 32% RSS respectively. Milk yield for the three experimental groups were 11.17, 11.66 and 11.85 kg/animal/day with no significant differences among them while the corresponding values of yield as 7% FCM were 9.57. 10.10 and 10.82 kg/head/day for CR, TR1 and TR2 respectively. Feed cost of the three scenarios were L.E. 16.59, 15.22 and 13.88/head/day, while three applied rations cost were L.E.16.8. 15.0 and 14.25/animal/day. The differences regarding revenue from milk yield seem to be significant between CR and both TR1 and TR2 being L.E. 16.70 vs. L.E. 20.35 and 23.62 respectively. Regarding S2 and S3 that formulated by computer, the costs reduction were 9.00% and 19.52% compared with scenario one (CR) Whereas S2 and S3 (TR1 and TR2) that applied in vivo its costs were reduced by 11.00% and 15.00% compared with control ration. From the present results it could be concluded that inclusion either CSS or RSS in the rations of lactating Buffaloes led to markedly reduce its feeding cost. Also applied proposed scenarios could be reduced berseem areas by 29.69% at national level, which be contribute to increases wheat production.
