| Abstract |
A numbers of 15 local breed (Zaraibi) and 15 exotic breed (Damascus) goats were used in the present study. The daily feed intake per doe (control ration) composed of 1.250 kg concentrate mixture + 4 kg green berseem (Trifloium alexanrium) or 1.3 kg berseem hay for each doe. Goats in group 1 were fed control ration (G 1) ; goats in groups 2 and 3 were fed as a control ration but replaced by 5% or 10% of concentrate mixture with sunflower seeds (G2) and (G3) in order.
The highest milk yield was recorded with goat's fed on 10% sunflower (1.86 kg/day for Damascus and 1.77 kg/day for Zaraibi goats) and the lowest in the control one (1.45 and 1.36 kg/day for Damascus and Zaraibi, respectively). The daily milk yield was the highest at the beginning of lactation, being 1.76, 2.18 and 2.21 kg/day for Damascus and 1.90, 2.02 and 1.95 kg/day for Zaraibi control; 02 and 03, respectively, and decreased gradually up to the end of the 4lh month of lactation (July) to be 1.46, 1.58 and 1.88 kg/day for Damascus and 1.40, 1.51 and 1.86 kg/day for Zaraibi control, G2 and G3, respectively.
The averages of milk fat and protein were significantly different (P<0.05) among the experimental treatment groups. The minimum fat values were 3.33 and 3.08% for Damascus and Zaraibi control group, respectively, while the maximum values (4.02 and 3.86%) were recorded in goat's fed on 10% sunflower (G3). Protein . content was lower in Zaraibi goats fed on control diet and 5% sunflower (3.80% and 3.99%), respectively. Damascus control goats showed insignificant higher casein N/TN values (69.29%) than the others. The values of rennet clotting time and curd tension were insignificantly different between both goat breed groups or among treatments, while, the differences in curd syneresis (CS) values due to breed and treatment groups were significant (P<0.05). the PH value of milk with zabady starter after inoculating for setting were 4.96, 5.05 and 5.08 for Damascus and for Zaraibi goats were 5.04, 5.11 and 5.12 in case of control: G2 and G3 treatments, respectively.
