| Abstract |
This study was carried out in Sids Experimental Station. The objective was to compare the effect of feeding rice straw or corn stalks either treated mechanically (by cutting) or chemically (by urea) or biologically (by fungus penicillium funiculisium) on the performance of growing Ossimi lambs. A feeding trial of 154 days was carried out with 36 female Ossimi lambs divided into 6 similar groups of26.00 kg initial body weight, on average. Groups were randomly assigned to the foil wing feeding. Gr. (I) mechanically treated rice straw. Gr. (2) the mechanically treated corn stalks, Gr. (3) chemically treated rice straw. Gr. (4) chemically treated corn stalks. Gr. (5) biologically treated rice straw and Gr. (6) biologically treated corn stalks. Roughages were fed Ad-Lib. In addition, concentrate was fed to all groups at 2% of their body weight. Moreover. 6 digestibility trials were carried out with 18 Ossimi rams to evaluate the six experimental rations.
Some rumen liquor and blood parameters were measured at successive Post feeding sampling hours. The efficiency of feed utilization, as well as economic evaluation was determined.
The results showed the following:
Groups fed the biologically and chemically treated roughages showed higher daily body weight gain, efficiency of feed utilization and lower feed cost to produce live body weight gain than groups fed mechanically treated roughages.
Values obtained for rumen liquor and blood parameters for all groups were within normal range for healthy rams.
From the results, it can be concluded that we can use either fungus penicillium funiculisums or urea in treating poor-quietly roughages to improve both their protein and energy contents.
