“…The results indicated that 30% olive cake with 1% bentonite followed by 60% olive cake with 0.5% bentonite and 30% olive cake with 0.5% bentonite as a partial replacement for clover hay improved the REE of diets by 121.83, 118.86% and 115.09%, .respectively when compared with the control diet. The results of this study are in agreement with those of Mehrez and Mousa (2011) found that feeding growing rabbits on diets containing 20, 25 and 30% olive pulp decreased the cost of feed per kg gain by 9.30, 19 and 21.5%, While economic the efficiency values were raised with olive pulp supplementation by 15.99, 36.86 and 42.96% respectively, compared with rabbits fed the commercial diets. The same trend was noticed for the Mostafa et al, (2003) who found that the feed cost per kg gain were relatively lower than the control when lambs were fed rations contained 15-35% olive cake.…”

“…In this respect, Mousa (2000) observed no significant differences in serum concentrations of albumin, globulin, total lipid, glucose, creatinine, AST, ALT and urea-N-by feeding the growing lambs 25% olive pulp. Also, Mehrez and Mousa (2011) found that concentration of total protein, albumin globulin, cholesterol, urea-N-, AST and ALT did not differ significantly with olive pulp inclusion in rabbit diet at levels of 20, 25 and 30%. Elkerdawy (1997) reported that levels of total protein, AST, ALT and creatinine were not significantly affected by olive pulp inclusion.…”

This study carried out to determine the effects of substitution with 30 and 60% of olive cake instead of dietary clover hay in the diet without or with bentonite at levels of 0.5 or 1%on growing rabbit performance. Eighty-four weaning New Zealand White (NZW) rabbits about 6 weeks old and 789 ± 37.59g average live body weight were randomly assigned to seven groups, each with three replicates (of 4 rabbits) in a growth trail lasted for 8 weeks. Experimental diets were as follows: diet 1: A control without olive cake, diets 2, 3 and 4: 30% of clover hay was replaced with olive cake and diets were supplemented with zero, 0.5 and 1% bentonite respectively, diets 5, 6 and 7: 60% of clover hay was replaced with olive cake and diets were supplemented with zero, 0.5 and 1% bentonite, respectively. Results could be summarized as follows: 1-Feeding rabbits on diets with 30% olive cake plus 1% bentonite significantly resulted in the best final body weight, daily weight gain, feed conversion ratio, dressing %, ether extract digestibility coefficient, nitrogen balance and DE also it gave the highest relative economic efficiency. However, feed intake, digestibility coefficients of DM, OM, CP, CF and nutritive value in terms of TDN and DCP were not significantly affected by the different treatments. 2-Feeding rabbits on diets with 30% olive cake plus 1% bentonite significantly resulted in the best total volatile fatty acids concentration. However, ammonia concentration was not significantly affected by the different treatments. 3-Data showed significantly increased in globulin with 30% olive cake with or without bentonite. However, there were significantly decrease in the value of plasma cholesterol and total lipids for rabbits fed on diets 30% olive cake plus 0.5 and 1%. 212WALAA SALAMA et al.Conclusively, it could be recommended to incorporate olive cake with nucleus at the rate of 30%of the rabbit diets to replace clover hay provided that supplementing the diet with 1% bentonite to improve the performance and economic return of the rabbit production.

“…Otherwise, a high fat content in the olive cake might lead to nutritional and technological problems that should be checked in future research in order to assess safe maximal inclusion limits. Preliminary results obtained with local breeds (Kadi et al, 2004;Mehrez and Mousa, 2011) have shown that use of olive cake in fattening diets is safe up to dietary levels of 25%.…”

Olive cake is one of the main agro-industrial co-products in the Mediterranean area of Spain, with high availability almost all year round. In addition, most of the product is dehydrated, which increases its interest in monogastric species such as rabbits. Nineteen samples from various Spanish oil mills using different processing methods were analysed for their chemical composition and in vitro digestibility. The average composition was [in dry matter (DM) basis]: ash (9.64%), neutral detergent fibre (52.0%), acid detergent fibre (36.8%), acid detergent lignin (19.1%), crude protein (CP) (11.3%), insoluble neutral (8.0%) and acid detergent crude protein (5.15%), ether extract (10.9%) and gross energy (21.9 MJ/kg). DM and CP in vitro digestibility were, on av., 53.4 and 41.4% respectively. High variability was observed among the samples for most of the traits studied. Fibrous fractions were highly correlated among them and negatively with ether extract content, whereas CP was little related to other feed components. A stepwise regression analysis allowed us to determine regression equations to predict DM and CP in vitro digestibilities from chemical composition (R 2 =0.80 and 0.91, respectively). As regards the current results, olive cake has a potential use for rabbits as a source of insoluble fibre and lignin. Crude samples (not oil extracted) combined with sieving to retain the smaller particles have an additional interest, because of their higher energy value and significant supply of high quality fat.

“…The olive and olive-derived industries are of an special importance in the Mediterranean area (Martin Garcia et al, 2003). Olive pulp has high nutritive value and is available in large quantities in North Sinai (Mehrez and Mousa, 2011). Olive is extensively cultivated in the new reclaimed area in Egypt (Moustafa et al 2008).…”

“…Olive by-products have been successively fed to rabbits (El-Kerdawy, 1997;Abd El-Galil, 2001;Abd El-Ghaffar, 2002;Mousa and Abdel-Samee, 2002;Abdel-Samee et al, 2005 andMehrez andMousa , 2011). Therefore, the present study was carried out to investigate the effects of partial substitution of barley grains by olive pulp in does and growing rabbit's diets on nutrients digestibility, nitrogen balance, productive and reproductive performance, growth performance and economical efficiency, under the conditions of North Sinai, Egypt.…”

The effects of feeding four dietary treatments containing 0, 20, 25 and 30% olive pulp without nucleolus as replacement for barley grains to does and growing rabbits on nutrients digestibility and nutritive values, productive and reproductive performance, growth performance and economical efficiency were studied. The digestibility of DM, CP and CF significantly (P<0.05) decreased with increasing olive pulp level up to 30%. However, digestibility of OM was not significantly affected by olive pulp inclusion. The gestation period, litter size at birth and at 28 days and litter weight at birth were insignificantly affected by olive pulp inclusion. The results indicated significant differences (P<0.05) among treatments in bunny weight at birth, at 21days and at 28 days, litter weight at 21days, at 28 days and at 35 days of age (weaning age), daily gain from birth to 21 days and from birth to 28 days and viability (%) from birth to 21 days, from birth to 28 days and from birth to weaning. No significant differences were observed in total milk yield among doe rabbits fed olive pulp (OP). The growth performance traits, the daily body weight gain significantly (P<0.05) decreased by increasing OP level more than 25%. Rabbits fed diets containing olive pulp can reduce production costs. Accordingly, olive pulp without nucleolus could be used successively and safely instead of barley in feeding doe rabbits during gestation period up to 25% , up to 20% during lactation period, and up to 25% for growing rabbits without adverse, under North Sinai conditions.
