“…Economic efficiency was higher with 50% DLF-ration (R3) than that of the other rations. The present results are in harmony with those recorded by Paek et al (2005) who showed that income per head was higher in 50% substitution level of DLF. Ration containing different levels of DCLO was economically feasible than that free from it respecting cost effective diet for pigs.…”

“…Further study conducted by Westendorf et al (1998)revealed that cafeteria food waste (CFW) plus energy supplement at 50% of the level of corn/soybean meal (CSM) resulted in gains not different from pigs fed the CSM diet in the finishing period of pigs. Paek et al (2005) reported that daily gain was not affected by dried leftover (DLF) substitution level up to 75%of formula feed. While, daily was gain markedly decreased at 100% substitution level.…”

his experiment was conducted to study the nutritional and economical evaluation of inclusion of hotels leftover food in growing lambs rations. Fifteen crossbred lambs (Ossimi × Finnish) with 23.5±0.3 kg average live body weight of, and 7 months of age were distributed into 3 similar groups (5 lambs each) and randomly assigned to 3 experimental rations. The experimental rations were formulated from concentrate feed mixture (CFM) that partially substituted by 0, 25 and 50% of dried leftover food (DLF) for CFM1, CFM2 and CFM3, respectively, plus corn silage. The experiment lasted 120 days. Results indicated that most nutrient digestibilities were markedly improved with increasing level of DLF in ration. Feeding values expressed as DCP did not significantly differ among the experimental rations, while TDN values were significantly improved with increasing the level of DLF. Ruminal pH values were significantly decreased with increasing DLF level at 3 hrs post feeding, however, concentrations of ruminal NH 3 N and TVFA´s were not affected by inclusion of DLF. No significant differences were observed in blood constituents among the experimental groups. Moreover, improving in average daily gain and the lowest feed cost to get one kg gain were observed with ration containing 50% DLF (R3), recording 10.97% and 12.44%, respectively. At the same time, the positive percentage of DLF gave the highest economic efficiency. It was concluded that inclusion of DLF in growing crossbred lambs' rations up to 50% in CFM improved their performance.

“…The improvement of economic efficiency for diets contained FWOC 30% could be related to the high feed conversion as well as to the positive effect of including FWOC on feeding value and decreasing feeding cost /h/d. The present results are in harmony with those recorded by Paek et al (2005) who reported that income per head was highest in 50% substitution level of dried leftover food (DLF).

his study aimed to evaluate the effects of diets composed of ecological food waste (mixture of food waste from hotels and olive cake(FWOC)) on lactating goats productivity compared with traditional diets. The effect of inclusion mixture of food waste and olive cake in diets of Zaraibi goats on nutrients digestibility, rumen function, milk yield, milk composition and some blood parameters were studied. A feeding trial was conducted using twenty four Zaraibi goats (32.33+0.2Kg LBW and aged 3-4 years) at late pregnancy (one month before parturition). Animals were assigned into three similar groups (8 animals each) using the randomized complete block design. They were fed as groups on a basal ration, where concentrate feed mixture (CFM) was 50% of requirements according NRC (2007); while berseem as a roughage was offered at libitum.The tested rations were formulated from concentrate feed mixture (CFM) that partially substituted by 0, 15 and 30% of FWOC for CFM1, CFM2 and CFM3, respectively, along with berseem as a roughage portion to formulate the experimental rations R1 (Control), R2 and R3 as tested one. Results showed that nutrient digestibility coefficients and feeding values were improved with the higher level of FWOC (30%) in ration, than R2 and R1 (control). NH3-N values and TVF'A concentrations in the in rumen liquor were increase with increasing the level of FWOC up to 30% (R3) in ration. The vice versa trend was found among dietary treatment respecting pH values in rumen liquor. Actual milk yields were significant higher with R3 (1269.1g/d.) than control ration (R1 1047.6 and R2 1130.0 g, respectively). Concerning milk composition, R2 rations significant increased fat percentage compared with R3 ration and control one, while insignificant differ was observed with milk protein percentage among treatments, the highest value in R3. Improvement respecting milk TS was observed with FWOC rations compared with control ration with insignificant differences. No significant differences among experimental rations regarding all offspring performance measurements. At the end of the experimental period, plasma total protein was affected significantly (P<0.05) by the experimental rations with the highest value (7.75g/dl) was occurred with R3 and the lowest one (6.85g/dl) was with R1. Economic efficiency was improved by feeding ration that contained30% FWOC (R3) in comparison with R1. This study concluded that considerably to use mixture of food waste and olive cake up to 30% level could be recommended for formulation the rations of lactating Zaraibigoats. It was concluded that use 30% of mixture food waste and olive cake was more effective in lactating goats. It can pronounced enhance feed intake, digestibility, feeding values, milk production, feed efficiency, some blood parameters and economic efficiency evaluation of lactating goats.

“…In relation with this point, McClure et al (1970) found that when 50% of DLF was proportion for commercial diets in ruminant, nutritional quality of final feed was good enough to meet nutrient requirement. Further study achieved by Paek et al (2005) reported that average daily gain was not affected by (DLF) substitution level up to 75% of formula feed. While, the daily gain markedly decreased at 100% substitution level.…”

Aim of this study was to evaluate the effect of inclusion dried leftover food (DLF) in the ration of crossbred calves (Balady x Friesian), on their growth performance, rumen function and blood parameters through a comparative feeding trial. Fifteen male crossbred calves (258±1 kg), were randomly assigned into three similar groups (five in each) and fed the tested rations for 16 weeks, as an experimental period. The tested rations were formulated from concentrate feed mixture (CFM) that partially substituted by 0, 20 and 40% of DLF for CFM1, CFM2 and CFM3, respectively, plus bagasse as a roughage portion for formulate the experimental rations R1 (control), R2 and R3 as tested one, respectively. Results showed that most nutrient digestibility coefficients and feeding values were improved with the higher level of DLF (40%) in ration, than R2 and R1 (control). NH3-N and pH values in rumen liquor were decreased with increasing the level of DLF up to 40% (R3) in rations. The vice versa trend was found among dietary treatments respecting TVFA´s concentrations in the rumen. Insignificant differences among tested rations in respect of most blood metabolites were found. Total body weight gain and daily gain were significantly higher only with (R3) than those of R1 (control). Economic efficiency was improved by feeding ration that contained 40% DLF (R3) in comparison with R1. This study concluded that considerably to use dry leftover food up to 40% level could be recommended for formulation the rations of crossbred cow calves.
