摘要

Abstract A 90 - day feeding trial was conducted to evaluate Mexican Sunflower leaf (MSL) as dietary fiber source in sheep diets. Straight diets were formulated to contain the MSL at dietary levels of 0%, 15%, 30% and 45% as replacement for wheat bran. Sixteen (16) West African dwarf ewe weighing 19.50 to 22.46kg were allotted to the 4 diets containing four replicates per treatment with 1 ewe per replicate in a completely randomized design (CRD). Ewes were given ad libitum access to feed and water and routine vaccination and medication followed standard procedures. Parameters measured were changes in feed intake during early, mid and late lactation, Feed Conversion Ratio (FCR) and DM : LW %. Data were analyzed using descriptive statistics and ANOVA. There were significant (p diet A (17.80kg) > diet D (17.60kg) although no statistical significance (P>0.05) was observed. There was no significant correlation between live-weight at mating and duration of pregnancy or live-weight at mating and lambs birth weight. Inclusion of up to 30% MSLM in the diets of lactating ewe appeared most beneficial to sheep as it had no negative effects on dry matter and nutrient intake.
