The present study was conducted to evaluate the effect of commercial exogenous fibrolytic enzyme (EFE) mixture added at 1.5 and 3.0 g (cellulase 4,000 microM glucose/g/h + xylanase 7,990 microM xylose/g/min; 50:50 w/w) per kilogram of dry matter (DM) of feed on nutrient digestibility, milk production, milk composition, and some blood constituents in lactating Murrah buffaloes. Eighteen buffaloes were allotted to three dietary treatments, on the basis of milk yield (8.48, 8.52, and 8.53 kg/day) and days in lactation (68.5, 80.33, and 82.00) for 90 days. The buffaloes were fed a total mixed ration (TMR) comprising of 45% chaffed wheat straw, 15% chopped green maize, and 40% concentrate on DM basis (control group), the same TMR plus EFE at 1.5 g/kg DM (T-1 group) and the same TMR plus EFE at 3.0 g/kg DM (T-2 group) supplemented through the concentrate mixture. There was no effect of fortifying EFE mixture on DM intake and crude protein intake (grams per day) whereas total digestible nutrients intake (kilogram per day) was higher by (P < 0.05) 12.53% in T-1 group over that of control, and there was no significant difference between T-2 and control groups. The average daily milk yield and 4% fat-corrected milk (FCM) yield was higher (P < 0.05) by 12.99% and 15.17% in T-1 group as over that of control, and there was no difference between T-2 and control groups. There was no (P > 0.05) difference in blood glucose and blood urea nitrogen concentration in different experimental groups. It is concluded that supplementation of cellulase and xylanase mixture at 1.5 g/kg of DM of TMR containing wheat straw (45%), green maize (15%), and concentrate (40%) on DM basis significantly increased (P < 0.05) the average daily milk yield and FCM yield in Murrah buffaloes due to improved dietary fiber digestion.

“…An increase in CP level might be resulted in increased ruminal ammonia N (NH 3 -N) concentration. Increased DMI with increased in dietary CP level might be due to high concentration of ruminal NH 3 -N that led to increased ruminal microbial proliferation, fermentation, and digestibility, and thus, enhanced nutrient intake (Javaid et al 2008). The DMI was also influenced (P<0.05) by interaction between energy and protein.…”

“…Energy supplementation might cause a depression in ruminal pH. The low NDF digestibility in lambs fed highenergy diets might be attributed to their low ruminal pH because reduced ruminal pH is known to depress fiber digestion (Javaid et al 2008). Firkins et al (1986) reported that when roughage based diets high in energy content were fed; ruminal pH was reduced resulting in decreased NDF digestibility.…”

“…Enzose (corn dextrose), corn steep liquor, maize bran, maize oil cake, and maize gluten 30% are the products of maize industry and are potential sources of protein and energy for ruminants Sarwar et al 2004;Javaid et al 2008) and are generally used in fattening ruminants. Supplementation of these sources not only enhances the protein and energy contents of diet but also results into increased nutritional worth of corncobs ).…”

Thirty-six Thalli male growing lambs were used in a completely randomized design with 2 x 2 factorial arrangement of treatments to evaluate the effect of varying levels of energy and protein on nutrient intake, digestibility, weight gain, and gain to feed ratio. Four experimental diets, i.e., low energy-low protein (LE-LP), low energy-high protein (LE-HP), high energy-low protein (HE-LP), and high energy-high protein (HE-HP) were formulated. The low- and high-energy diets contained 2.3 and 2.7 MJ/kg dry matter (DM) with 12% and 14% of crude protein. The lambs were fed ad libitum. Dietary energy and protein levels and their interactions influenced the nutrient intake. Maximum dry matter intake was noted in animals fed LE-HP diet followed by LE-LP, HE-HP, and HE-LP diets. Digestibility of DM and N increased (P < 0.01) and that of neutral detergent fiber decreased (P < 0.01) linearly with increasing levels of dietary energy and protein. Digestibility of N was only affected by protein level and interaction between energy and protein levels. Average daily gain was higher (P < 0.01) in lambs fed HE-HP diet followed by LE-HP, LE-LP, and HE-LP diets. Dietary energy and protein levels and their interaction had significant effect (P < 0.01) on gain to feed ratio.

“…These may be due to that the three experimental rations were balanced in their chemical composition, specially crude protein (Table 1) which the protein contain in animal diets is the main limiting factor that affect blood proteins concentration and as reported in other studies (Chumpawadee et al, 2006;Javaid et al, 2008), blood urea concentration correlated to ruminal ammonia concentration. Thus, the present results clearly indicate that protein metabolism is mostly unaffected by inclusion biologically treated rice straw in ewe-lambs rations as well as the level of dietary protein is satisfactory to cover animal allowances.…”

This study aimed to investigate effects of inclusion biologically treated rice straw with Trichoderma viride or Trichoderma reesei in ewe-lambs ration on its productive and some physiological response. Thirty crossbred (Rahmany X Romanof) ewe-lambs (three months old and 17±1.13 kg body weight) were assigned randomly to three groups (10 animals each). The first group was fed ration contained 55% concentrate feed mixture and 22.5% clover hay plus 22.5% Untreated Rice Straw (URS), group two and three were fed rations contained rice straw treated with T. reesei (TRSR) or T. viride (TRSV), respectively. No significant differences were observed in nutrients digestibility, Total Digestible Nutrients (TDN), nitrogen retention and nitrogen utilization efficiency among the experimental groups. Treatments did not record differences in TVFA's, ammonia concentration and pH value of rumen liquor at 0, 3 and 6 h post feeding. Also no significant differences were observed among the experimental groups in blood metabolites, while albumin, cholesterol and progesterone concentration increased (p<0.05) as animal age increased. Groups fed TRSV and TRSR recorded lower (p>0.05) values in total gain, average daily gain and worst (p>0.05) feed conversion as DM and CP compared to the control group. It could be concluded that using biologically treated rice straw in ewe-lambs ration had no adverse effects on nutrients digestibility and nitrogen balance as well as physiological response, while insignificantly decreased (p>0.05) growth performance.
