Effect of Jatropha cake on milk yield, milk composition, some physiological body reaction, blood composition, estrus incidence and pregnancy rate in Zaraibi dairy goats
Abstract: The aim of this study was to investigate milk yield. milk composition physiological body reaction. blood composition. regulation oestrus and pregnancy rate as affected by replacement of soybean with treated jatropha cake in Zaraibi dairy goat's rations. Twenty-four Zaraibi dairy goats showing healthy were divided into two groups. The control group (n=12) was fed basal ration contained concentrate feed mixture (CFM) with fresh berseem (Trifolim alexandrium). while the treatment group received (CFMJ=concentrate fed mixture with treated jatropha cake) where, replacement of 50% soybean meal with treated jatropha cake (TJC). Nutrient digestibility and nutritive value were determined by using Acid Insoluble Ash.
Results of digestibility coefficients of DM. OM. CF. EE and nutritive values (TDN) showed insignificant differences among tested groups. Meanwhile, digestibility coefficient of CP and DCP for R2 was significantly (P<0.05) higher than the control group (R1)., No significant differences were recorded among the tested groups in daily milk yield and milk composition. The physiological measurements were physiological body reaction included: rectal temperature (RT), skin temperature (ST). coat temperature (CT), respiration rate (RR) and heart rate (HR). Moreover, Blood samples. regulation of oestrus and pregnancy rate were evaluated. The results indicated that significant differences (P<0.05) between RT, ST and RR but. non-significantly with CT and HR. The blood parameter reported significant (P<0.05) for jatropha goat compared to control in total protein, albumin, glucose. zinc. calcium. phosphorus and magnesium. The differences in regulation of oestrus activity was significantly higher (P<0.05) for treated group than control. Pregnancy rate in group fed jatropha was more than the control group (P<0.05).Feed cost decreased 11.8% as compared to control group. Mean while. the return was increased by 8.14% for G2 group. In conclusion that the substitution of soybean with treated jatropha cake has a very low risk of anti-nutritional factors and can improve reproductive performance and this will improve stockholder income.
