Abstract
Three summer green forages were studied (Sesbania Sesban, Sesbania-
Sorghum mixture and Sesbania-Millet mixture) compared with control in four
rations: Ration A (control): 100% from requirements according to NRC from
Concentrate Feed Mixture (CFM)+Rice straw. Ration B: 50% from requirements
ofNRC from CFM+Sesbania ad lib. Ration C: 50% from requirements ofNRC
from CFM+Sesbania-Sorghum mixture ad lib. Ration D: 50% from requirements
of NRC from CFM+Sesbania-Millet ad lib. Four digestibility trials were
conducted to evaluate the experimental rations. Twenty four growing lambs
averaged 22.5 kg body weight were divided into four groups to evaluate the four
rations.
The differences among all rations in digestion coefficients of DM, OM,
CP, NFE and nutritive values as TDN of tested rations were not significant, but
DCP% of control was significantly lower than other rations .The nitrogen balance
was positive in all rations. The ruminal pH values after feeding ranged from 5.88
to 6.45. The NH3-N and TVFA’s were significantly higher post feeding than
before feeding. The differences of total number of protozoa and microbial protein
at 4 hrs post feeding were not significant among all rations.
The daily body gain of all treatments were nearly similar but the differences
among four groups were not significant. The feed conversion of rations containing
green forages was better than control. The best economical efficiency was showed
in Sesbania-Sorghum mixture + CFM and Sesbania-Millet mixture + CFM.
It concluded that the Sesbania-Sorghum mixture or Sesbania-Millet mixture
cultivated in new reclaimed sandy soil.
