  Five types of silage were made from Vegetable and Fruit Market Wastes (VFMW) to evaluate silage quality. The different types of silage were, VFMW (S1), VFMW+5% ortho-p-acid (S2), VFMW+5% formic acid (S3), VFMW+5% 1: 1 ortho-p-acid: formic acid (S4) and VFMW+5% sodium acetate (S5). After 21, 42 and 64 days the siloes were opend and the silages characteristics were examined. Supplementation of chemical agents to VFMW silage (S2, S3, S4 and S5) were significantly increased dry matter, organic matter, crude protein, ether extract and nitrogen free extract contents, while crude fiber content was significantly decreased (p<0.01) with treated silage compared with control (S1). In vitro dry matter (p<0.01) and organic matter (p<0.05) disappearances were significantly higher with formic acid+ortho-p-acid and sodium acetate (S4 and S5) treated silage followed by ortho-p-acid and formic acid (S2 and S3) and then control (S1). Silage pH value was decreased (p<0.01) with adding ortho-p-acid and sodium acetate to silage, while, silage butyric acid concentration was increased (p<0.01) with ortho-p-acid and decreased (p<0.01) with the combination of acids adding to silage compared with control. On the other hand, ammonia-N, lactic acid were not among treatments. Silage pH, ammonia-N, butyric acid and lactic acid concentrations were increased (p<0.01) with time of ensiling. Nine castrated goat's male average (26.2 kg and 4 years age) were divided into three groups using 3x3 Latin square design with 30 day periods to study the effect of treatments on rumen activity and nutrient digetibilities. DM, OM, CP, CF, EE and NFE digestibilities were increased (p<0.05) with treated groups compared with control. Rumen total nitrogen, true protein nitrogen and non protein nitrogen contents were increased (p<0.05) while, ammonia-N content was decreased (p<0.05) with treated groups compared with control. Fifteen lactating Zaraibi goats after seven days of parturition were ranked to three groups using 3x3 Latin square design with 30 day periods to study the effect of treatments on milk yield and composition. Animals were fed on Concentrate Feed Mixture (CFM): VFMW silage (S1), CFM: VFMW treated with 5% formic acid (S2) and CFM: VFMW treated with 5% sodium acetate (S3). Milk yield and 4% FCM were increased (p<0.01) with treated silage. Yields of milk contents were higher (p<0.05) in treated group compared with control. However in milk, total protein, fat, lactose and solids not fat contents were not differed significantly among treatments. Chemical treated silage improved (p<0.05) feed efficiency (milk Yield/Dry Matter Intake (DMI) and 4% FCM/DMI) of VFMW silage. Blood serum glucose increased (p<0.05) while, urea and total lipids decreased (p<0.05) with treated groups compared with control.

  Fifteen lactating buffaloes after seven days post-parturition were divided randomly into three groups (of 5 animals each) to study the effect of adding By-Pass Cement Dust (BCD) level to the buffalo’s diets on the coefficients of nutrient digestibility and milk yield and composition using complete random block design experiment with 90 days period. The control group was given a basic diet consisting of (60% Concentrate Feed Mixture (CFM): 20% berseem clover: 20% rice straw), the second and third groups were fed the control ration plus 7.5 and 15 g/head/day BCD, respectively. The CFM for each animal was offered individually once daily at 8.00 am, while berseem clover and rice straw were offered at 10.00 am. Individual milk samples were collected every two weeks of the experimental period for chemical analysis. After 4 h of the morning meal, grab samples and blood serum samples were collected in the last day every month for chemical analysis. Nutrients digestibility coefficient of organic matter, crude protein and crude fiber were significantly higher with animals fed low level followed by high level of BCD and then control. Also, dry matter, ether extract and nitrogen free extract digestibilities followed the same trend while the effects of treatments failed to be significant. Supplementation of low level of BCD to buffaloes rations increased yields of milk (p<0.05), 4% FCM (p>0.05) and milk constituents (p>0.05) compared with other treatments. Milk fat, protein and lactose contents were insignificantly increased with animals fed BCD compared with control. While, total solids, ash and solids not fat contents were not differed among treatments. Milk P, Mg and K contents were significantly higher with animals fed BCD compared with control. Feed efficiency as Milk yield/dry matter intake (DMI) (p<0.05) and FCM/DMI (p>0.05) were higher for animals fed BCD than that fed control. Blood serum total protein, urea and glucose were higher (p<0.05) in animals fed on low BCD supplemented rations, while, other blood serum parameters were not affected by treatments. Also, blood serum Ca, Na and Fe were significantly higher in animals fed on low BCD supplemented rations compared with control. It could be concluded that low BCD supplementation (7.5/head/day) to diets improved nutrients digestibility coefficients, milk yield and milk constituents than other treatments.
