Effect of Feeding Olive Cake Supplemented With or Without Bentonite on Performance of Growing Rabbits

Abstract

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.

Influence of Using Olive Cake Meal With or Without Sodium Bicarbonate on Productive Performance of Growing New Zealand White Rabbits

“…They noted that the highest FI was recorded by rabbits fed control group (basal diet without additives), whereas the lowest FI was for rabbit groups fed diet with 10% OCM without CA. Also, Walaa et al (2016) reported that feeding rabbits on diets with 30% OCM plus 1% bentonite significantly resulted in the best final body weight, daily weight gain and feed conversion ratio. However, feed intake was not significantly affected by the different treatments when growing NZW rabbits fed diets with 30 and 60% of OCM without or with bentonite at 0.5 or 1%.…”

“…Similarly, Azazi et al (2018) reported that carcass, liver, heart, giblets and dressing percentages in rabbits fed 10% OCM recorded higher values compared with other dietary treatments. Also, Walaa et al (2016) showed that carcass traits were significantly affected by OCM inclusion. While, Bakr et al (2019) showed that olive pulp inclusion in growing rabbits diets at varying levels (15, 20 and 25%) did not show any significant effect on all carcass traits.…”

“…Also, Mehrez and Mousa (2011) noted that total protein, albumin, globulin, cholesterol, urea-N, AST and ALT for rabbits fed diets containing olive pulp at levels of 20, 25 and 30% were not significantly affected. Furthermore, Walaa et al (2016) reported that globulin significantly increased in rabbit diet contained 30% OCM with or without bentonite. While, the values of plasma cholesterol and total lipids for rabbits fed diets with 30% olive cake plus 0.5 and 1% bentonite are significantly reduced.…”

“…In addition, The diets contain 10 % or 20 % OCM without citric acid recorded lower digestibility coefficients in comparison to diets supplemented by citric acid. Also, Walaa et al (2016) decided that the inclusion of OCM in rabbit diets resulted in non-significant differences in dry matter (DM), organic matter (OM), crude protein (CP) and crude fiber (CF) digestibility coefficients. However, the differences were significant for the ether extract (EE) and NFE digestibility coefficients.…”

“…On the other hand, rabbits fed on the diet supplemented with 10% olive cake meal without NaHCO3 had the lowest values of all traits. Salama et al (2016) showed that carcass traits were significantly affected by olive cake meal inclusion. While, Bakr et al (2019) showed that olive pulp inclusion in growing rabbits diets at varying levels (15, 20 and 25%) did not show any significant effect on all carcass traits.…”
