Effect of including filter cake blocks in lactating goats rations on digestibility ansd productive performance
Abstract: This experiment was carried out to investigate the effect of partial substitution of concentrate feed mixtures (CFM) with filter cake blocks (FCB)'(with different level of filter cake (FC), in rations for lactating does on digestibility milk yield and milk composition. Thirty Egyptian Baladi lactating does averaged 33030 ±1.5 kg live body weight (LIBW) and aged 3-4 years were divided randomly into three similar group's
The control ration (RI) consisted of concentrate feed mixture (CFM) 50 % , berseem hay (BS) 30% and wheat straw (WS) 20% as (control group), whereas the second and third groups received the same control ration with 50% of CFM protein was substituted by FCB I (with 40% FC) as group RII or by FCB2 ( with 48% FC) as group RIII. respectively. Animals were fed according to NRC.(1989) allowances for goats. Three
digestibility trials were conducted with 9 mature bucks to evaluate the nutritive value of tested rations.
Results showed that the digestibility coefficients of CP,CF and nutritive value as TDN, ME and DCP for RII group were significantly (P<0.05) improved as compared with the Rl group (control). Milk yie1d and fat corrected milk yield significantly (P<0.05) increased with FCB I substitution. milk composition was no significantly affected -by -FCB substitution. whereas both fat and protein milk yields of goats fed RII ration were significantly higher (P<0.05)- than those fed control ration (RI). No, significant differences were detected among most tested blood constituents of all groups of lactating goats. except urea-N which was higher on tested groups (RII & RIII) than the control group RI. 1'vloreover, feed cost decreased by 8.82 and 14.71%, leading to an economical efficiency improvement by 41.30 and l2.32% , with RII (With 40% FC) and RIII (with 48% FC), respectively than with RI group (control). In conclusion. partial substitution with FCB 1 (with 40% FC) could be recommended for lactating does rations as this wi1l improve stockholders income.
