Performance of lactating buffaloes fed rations containing cotton gin trash
|
|
Abstract: Seven lactating buffaloes-averaged 620 kg live body weight in 3rd to 4th partities were used after 7 weeks of calving for a 144 days experimental period using "Swing over” method to investigate the effect of partial replacing of concentrate feed mixture by cotton gin trash (CGT) on feed intake, nutrients digestibility, milk yield and its composition and economic impact for lactating buffaloes using the following experimental rations:
Control ration (CR): 60% of TDN and CP requirements from concentrate feed mixture (CFM) + rice straw (RS) ad lib.
1st tested ration (TR1): 50% of TDN and CP requirements from CFM + 10% of TDN and CP requirements from cotton gin trash (CGT) + RS ad lib.
2nd tested ration (TR2): 40% of TDN and CP requirements from CFM + 20% of TDN and CP requirements from CGT + RS ad lib.
The main results are summarized as follows:
1- the quantity of DM intake increased with increasing CGT ratio in the tested rations with no significant difference.
2- The OM and CP digestibilities of TR2 were significantly (P<0.05) lower than those of CR. While the DM digestibility was insignificantly (P<0.05) decreased with increasing CGT ratio in the tested rations (TR1 and TR2). 3- The CF digestibility of TR2 was significantly (P<0.05) higher than the others while the NFE digestibility of CR was significantly (P<0.05) higher than the others.
4- The nutritive value as TDN of TR2 was significantly (P<0.05) lower than that of CR while DCP of CR was significantly (P<0.05) higher than the others.
5- The differences of daily fat corrected milk (FCM) and chemical composition of milk between tested rations were not significant (P<0.05).
6- Inclusion of CGT in the buffaloes rations TR1 and TR2 tended to a decrease in feed cost as P.T./Kg FCM by 9.92 and 20.70% and increased in return /kg FCM .10.43 and 21.76% compared to animals fed CR (CFM + RS), respectively.
Cotton gin trash could be used safely, economically and successfully in formulating rations of lactating buffaloes up to 20% from requirements as a cheap ingredient.
