| Abstract |
The present experiment was carried out to investigate the effect of biological treatment of rice straw and sugar cane bagasse on their digestibility, feeding value, rumen and blood parameters and change of ruminal microorganisms (total bacterial, cellulolytic bacterial, protozoal and differential protozoal counts%). Rice straw (RS) and sugar cane bagasse (SCB) were treated with either yeast (Saccharomyces cerevisia) plus bacteria (Cellulomonas cellulans ) (YB) or yeast plus fungi (phanrocheate chrysosoporiun) (YF) or with the three organisms together (YBF). Twenty seven ossimi x Merino crossbred mature rams were used in nine digestibility trials (three rams in each trial ) to determine the digestibility coefficients and feeding values for the nine experimental fed rations. The treatments were : (I)- concentrate feed mixture (CFM) + berseem hay (contyrol). (2)-CFM + untreated RS ad lib.(3)- CFM + treated RS with (YB) ad lib. (4)-CFM+ treated RS with (YF) ad lib. (5) –CFM+ treated RS with (YBF) ad lib. ( 6)- CFM + untreated SCB ad lib. (7)- CFM + treated SCB with (YB) ad lib. (8)- CFM+ treated SCB with (YF) ad lib. (9) – CFM + treated SCB with (YBF) ad lib. Both roughages were chopped into (3-5 cm) before treated with one of the biological treatments. And a concentrate feed mixture to provide 50% of the recommended CB requirements for sheep. From the obtained results, it was found that Rs and SCB treated with (YB,YF and YBF) increased CB content and decreased CF and its fractions content compared with those of the untreated roughage. The biological treatments increased also nutrients digestibility coefficients and thus increased their feeding values as TDN and DCP of both RS and SCB compared with those of the untreated roughage and the control ration. Concerning ruminal parameters and change in ruminal microorganisms, it was found that the biological treatment (YBF) of RS increased ruminal PH value, while all other biological treatments of SCB decreased rumen PH values at 3hrs post feeding. However, all biological treatments of both Rs or SCB increased also ammonia- N and total volatile fatty aciddds (TVFA’s) at 3hrs post feeding . RS and SCB treated with(YBF or YF )increased total bacterial counts at 3hrs post teeding . RS treated (YBF or YF ) increased total cellulolytic bacterial counts, while SCB treated with (YB) at 3hrs post feeding. However , untreated RS, control ration, RS and SCB treated with (YBF) increased the protozoal counts at 3hrs post feeding. Concerning protozoa types it were found that Diplodinium, Epidinium and Entodinium had higher percentage in RS treated with (YB) untreated RS and control ration at 3hrs post feeding. Higher Diplodinium percentage was found in SCB treated with (YF), untreated SCB and control ration, while higher percentage of Epidinium was founf in SCB treated with (YBF,YF) and control ration. Higher percentage of Entodinium was found in SCB treated with (YBF,YF), untreated SCB and control ration at 3hrs post feeding than all the other treatments. Concerning blood parameters (Hb%, total protein, albiumin, urea, GOT and GPT) they were within the range of the normal values for healthy rams.
It was concluded that the biological treatments of roughages using yeast plus either bacteria or fungi or both microorgannnnisms could increase nutrient digestibility coefficients and their feeding values as TDN and DCP which can replace berseem hay in the control ration without any adverse effect on animal health and performance and can reduce cost of ruminants feeding.
