Relationship of residual feed intake on specific hematological and biochemical parameters in Rambouillet sheep

ALBERTO MURO REYES (2011)

Relationships of Residual Feed Intake (RFI) on hematological and biochemical parameters were determined in Rambouillet sheep. After feeding period of 42 days (research period), RFI was calculated in 1 6 rams and 24 ewes. Lowest negative and highest positive RFI (< 0.5 SD below the mean and> 0.5 SD above the mean, respectively) rams (n= 8) and ewes (n= 12) were selected. From RFI-categorized sheep, hematological and biochemical parameters were evaluated at day 0, 21 and 42 and at day 0 and 42 of the feeding period, respectively. Positive RFI ewes (less efficient) tended (p< 0.10) to have more red blood cells (RBC, IO6 uL)(9.66 vs. 7.68) and less Mean Corpuscular Hemoglobin (MCH, pg)(9.59 vs. 12.95) than negative RFI ewes. Positive RFI rams have (p< 0.05) more RBC (9.27 vs. 6.67) and White Blood Cells (WBC, 103uL)(10.25 vs 7.77), less Mean Corpuscular Volume (MCV; 30.98 vs. 44.11£ L …
