Effect of replacing maize silage with sweet potato vines silage in sheep ration
Abstract: This study was carried out to evaluate different levels of sweet potato vines silage (SPVS) compared with maize silage (MS) in sheep rations offered at different levels to determine silage quality, nutrients digestibility, nutritive values and some rumen parameters. Three adult rams in each were random distributed with an average of 59 Kg body weigh. The experimental rations were composed of: 1st ration (T1) :100 %MS, 2nd ration (T2) :(75%MS +25 %SPVS, 3rd ration: (50 %MS +50 %SPVS) 4th ration :( 25 %MS +75 %SPVS) and 5th ration: 100% SPVS, an rations were fed ad lib.
The results revealed that, SPVS was characterized by high contents of CP and NFE and low contents of CF and Ash than MS. MS silage had higher values of ammonia - N; acetic acid; butyric acid and lactic acid but SPVS had higher value of total acidity. The daily DM intake decreased with increasing SPVS ratio in experimental rations without any differences among all treatments. Digestibility of nutrients and nutritive values as TDN and DCP increased (P<0.05) with increasing SPVS ratio in the experimental treatments.
This investigation demonstrated that SPVS was a good substitution for MS Feeding SPVS with MS up to 75 %in sheep rations improved digestibility of nutrients, nutritive values and daily feed intake.
