    Silage characteristics and preference of sheep for wet brewer's grain ensiled with maize cob
    (Fundación CIPAV, Cali, Colombia, 2015) Ososanya, T. O.; Olorunnisomo, O. A.
    In order to meet the shortfall in feed supply and provide adequate nutrition for sheep during the dry season, wet brewer’s grain (WBG) was ensiled with 0, 10, 20, and 30 % of crushed maize cob (MC). The physical characteristics, pH and chemical composition of the silage mixtures were determined at 21 days of ensiling. Acceptability and preference of sheep among the silage mixtures were determined in a cafeteria feeding trial using eighteen West African dwarf (WAD) sheep. The experimental design adopted was the completely randomized design. The colour, smell and texture of the mixtures showed that all silages had acceptable physical attributes. The pH of silage varied from 3.40 - 3.80, indicating that the silage mixtures were adequately fermented. Silage scores however revealed that the best physical attributes were attained at 20 % inclusion of maize cob to WBG. Dry matter (DM) content of silage was 26.88, 31.44, 36.69, 43.50% while crude protein (CP) content was 23.44, 19.11, 14.00, and 12.00% for silage with 0, 10, 20 and 30% of maize cob respectively. Neutral detergent fibre increased from 40.33 - 62.67 % and acid detergent from 25.00 - 39.67% with increasing level of maize cob in the mixture. The coefficient of preference (CoP) and percent preference showed that WBG silage with 10% MC was more acceptable and preferred by sheep than other silage mixtures. While physical attributes of silage showed that the optimum level of MC inclusion was 20%, animal preference indicate that this level was less acceptable to sheep. Sheep may require more time to adapt to higher levels of MC in the silage mixture.

    An experiment was conducted to compare the utilization of tephrosia candida and leucaena leucocephala in mixtures with Panicum maximum as feed for small ruminants, using the artificial bag technique of feed evaluation. Three West African dwarf (WAD) sheep with rumen cannula were used for the experiment. T. candida was formulated into diets with P. maximum as diets A, B and C while L. leucocephala was formulated into diets with P. maximum as diets D, E and F in the ratio 3:1, 1:1 and 1:3 respectively for both legumes. The degradation characteristics indicated L. leucocephala – based diets as being more (P < 0.05) degradable in the rumen than the T. candida – based diets, with diet D having the highest potential degradability (a+b) value.

    Information needs of small ruminant rearers in peri-urban areas of Southwest Nigeria
    (2010-07) Abu, J. Z.; Adekoya, A. E.; Abu, O. A.
    The study aimed at recognizing the information needs of small ruminant rearers within households in three peri-urban areas of Oyo state and Ile-Ogbo in Osun state. The respondents were purposively selected and snowball technique was used to identify them. Focus group discussion and questionnaire/interview schedule were used to collect information for the study. It was discovered that 51.3% of respondents were aged 50years and above indicating that the rearing of small ruminants was also suitable for the more settled and slower citizens and that 73.6% of the respondent had some form of education. Majority of the respondents (87.6%) earned less than N5,000.00 monthly from small ruminants and 94.2% of them think rearing small ruminants is profitable. In addition, 77.7% of them reared small ruminants primarily for income generation. The study also revealed that the most important constraints to small ruminant production were theft, death from vehicles and pests and disease infestations and that the respondents needed information on small ruminant rearing in areas like feeding, management System, housing, disease Identification and record keeping.
