Abstract: | Three sweet potato varieties (TIS-87/0087; TIS-8164; TIS-2532.OP.1.13) and Green panic (Panicum maximum) were evaluated for forage quality in a completely randomized design (CRD) using 12 sole-fed lactating White Fulani cows
for 21 days, and 12 growing White Fulani and White Fulani x Brown Swiss calves for 77 days. Dry matter intake of cows ranged
(p < 0.05) between 131 g/Wkg
0.734 in TIS-87/0087 and 152 g/Wkg
0.734 in TIS-8164. Daily milk yields increased (p < 0.05) in TIS-87/0087 (2%) and TIS-8164 (5%), but decreased in TIS-2532.OP.1.13 (5%) and Green panic (19%). Mean (±SEM)
milk total solids (13.16 ± 0.05 g/100 g), ash (0.78 ± 0.01 g/100 g), protein (3.79 ± 0.07 g/100 g), fat (3.98 ± 0.06 g/100 g),
and lactose (4.62 ± 0.14 g/100 g) were significantly different (p < 0.05) among treatments. The White Fulani x Brown Swiss calves recorded about 10, 25 and 29% higher birthweight, milk intake
and bodyweight gains respectively, but about 3% lower dry matter intake than the purebred White Fulani calves. The rumen degradation
rates were similar (p > 0.05), while the rest rumen dry matter degradation characteristics were lowest (p < 0.05) for Green panic. Sweet potato forage could be used as sole feed or supplement for dry-season Green panic. |
