The objectives of this study were to determine the effects of high-forage diets with and without added dietary palm oil (high in palmitic acid) fed at equalized ME intakes on performance, plasma lipids, and carcass characteristics of growing ram and ewe lambs. Thirty-one Hampshire or Suffolk lambs (35.7 kg BW) were used in a 2 x 2 factorial arrangement of the following treatments: 1) rams, no palm oil (R-NPO); 2) ewes, no palm oil (E-NPO); 3) rams, 10.7% dietary palm oil (R-PO); and 4) ewes, 10.7% dietary palm oil (E-PO). Both diets consisted of 77% forage and 23% concentrate. Diet DM contained 15.0% CP and 2.14 Mcal of ME/kg (NPO) or 2.62 Mcal of ME/kg (PO). Lambs were fed individually specified amounts of diet based on BW to equalize ME intake (.20 Mcal of ME/kg of BW.75) for both dietary treatments. Lambs were weighed and feed intakes were adjusted weekly. Lambs were bled by jugular venipuncture on d 28, 56, and 84 and were slaughtered after they had been fed the diets for 90 d. Lambs fed PO had greater (P < .01) ADG and efficiency (ADG/ME intake) than lambs fed NPO. Plasma concentrations of cholesterol, high-density lipoprotein cholesterol, triglycerides, and nonesterified fatty acids were increased (P < .01) by feeding PO. Lambs fed PO were fatter than lambs fed NPO, as evidenced by greater subcutaneous fat thickness and kidney and pelvic fat. Ewes had greater (P < .01) subcutaneous fat than did rams.(ABSTRACT TRUNCATED AT 250 WORDS)
