Abstract
:
This study was to investigate the effect of 4 concentrate:roughage (C:R) ratios on productive and reproductive performance of Harri ewes. Forty eight ewes devided into four groups (12 each). group A given 80%C+20%R; B given 60%C+40%R; C given 40%C+60%R; D given 20%C+80%R. Data analysis was carried out using SAS, 2006 software. The increase in R ratio increased (P<0.05) crude protein production and rumen pH. Increaed C ratio improved estrus; total number of follicles, ovulation rate (95 and 90.9%) in A and B vs. (70.8 and 66.7%) in C and D. In contrast, increased R ratio improved conception rate (83.3 and 50%) for C and D vs. (20 and 27.3%) for A and B; twining rate (60 and 66.7%) for C and D vs. (14.3 and 16.7%) for A and B. improved but not significantly lambing (90 and 71.4%) for C and D vs. (50 and 66.7%) for A and B; prolificacy and reduced embryonic loss and increased P4 in C and D. Increased R ratio increased albumin, decreased urea and cholesterol, increased lambs body weight not weaning weight, increased milk yield in D and increased the yield of milk fat, protein, SNF, lactose and minerals. The increase in R ratio increased C18:2c, total PUFA and C16:0 fatty acid in milk.
