PHYSICO-CHEMICAL AND PREFERENCE EVALUATION OF ENSILED CORNCOB-LAYERS DROPPING BY YANKASA RAMS
Keywords:Corncobs, Ensiling, Layers droppings, Preference, Yankasa Rams
This study was carried out to evaluate the effect of ensiling graded levels of corncob and layers dropping (CCLD) on fermentative and nutritional characteristics of ensiled CCLD, short time intake and preference by Yankasa rams. Ground corncob was ensiled with poultry dropping in a ratio of 50:50, 60:40, 70:30 and 80:20, each ratio serves as treatment. The physical characteristics, pH and chemical composition of the ensiled CCLD were determined after 21 days of ensiling. Five Yankasa rams aged between 10 – 12 months with live weight ranged between 17 – 20 kg were used to evaluate acceptability and preference of the ensiled CCLD in a cafeteria feeding style in a completely randomized design (CRD). Data obtained were subjected to analysis of SAS and significant means were compared. The chemical content ranges between 9.12-10.84%. The changes in fibre fractions indicated that neutral detergent fibre ranges from 15.60-16.81% and acid detergent fibre ranges from 9.92-22.79% with increasing level of corncob in the mixture. Percent acid detergent lignin also ranges between 12.61-19.03%. The pH values ranged between 4.4-4.68. CCLD mixture with 70:30 ratio has a pleasant smell. Ensiled CCLD score revealed that the best physical attributes were attained at 70:30 and 80:20% inclusion levels. Percent preference of Yankasa sheep significantly (P<0.05) varied from 18.85 – 36.22 % and the order of preference was 70:30 > 80:20> 60:40 > 50:50. The coefficient of preference (CoP) and percent preference indicated that ensiled CCLD with 70:30 and 80:20 were more acceptable and preferred by Yankasa rams than the other graded levels. This finding suggest that ensiling corncob with layers dropping improves its nutritive value hence, it is recommended that farmers could ensile corncob with layers dropping at the ratio of 70:30 and 80:20 to the extent that it can be utilized as an alternative livestock feed.
