Nitrogen balance of Pregnant WAD ewe fed Mexican Sunflower leaf meal (MSLM) Based diets

Anthony Henry Ekeocha, Patience Olusola Fakolade.

Fifteen days prior to parturition, a study was conducted using sixteen West African Dwarf (WAD) ewes (Initial BW 24.4151.615kg) were used in a completely randomized design to study the effects of increasing level of mexican sunflower leaf meal (MSLM) on nitrogen balance. The experimental animals were assigned to 4 treatment groups A,B,C and D of 4 replicates each and were fed with grass (Panicum maximum)plus concentrate diet mixture of MSLM and wheat bran (WB) such that 0%,15%,30% and 45% of wheat bran was replaced by weight with MSLM gravimetrically. The experiment lasted for one week. Digestibility was determined using a 6-d total urine and fecal collection. Ewes were given adlibitum access to feed and water and routine vaccination and medication followed standard procedures. The 16 ewes were previously brought to heat (Oestrus) by synchronization and served by two rams (1:8). Parameters measured were nitrogen intake, nitrogen balance, nitrogen apparent digestibility and nitrogen retention. Data were analyzed using descriptive statistics and ANOVA. Animals on treatment B had the highest N-intake (17.4g/d), N faecal (1.5g/d), N absorbed (15.9g/d) and N balance (15.9g/d) and this was significant (P
