Profitability of diets, nutritive value, performance and cecal activity of growing rabbits fed bean vein hay

Abstract

A feeding trail was conducted to study effect of bean viens hay (BVH) on the growing rabbit’s performance, nutritive value and cecum activity and economic return of experimental diets that. Seventy two New Zealand White (NZW) rabbits (6 week of age) were divided into 6 groups and were fed 6 experimental diets inclusion BVH and Galzym® enzyme contains cellulase, xylanase, lipase, amylase, protease, pectinase, arabinase, phytase, α-galactosidase, and β-glucosidase additives. Group 1 fed negative control (basal diet without both BVH and Galzym®) and group 2 fed positive control diets (basal diet without BVH and with Galzym®). The 3rd and 4th groups fed 25% BVH substitution of clover hay without Galzym® (T3) and with Galzym® (T4). The 5th and 6th group’s rabbits fed 50% BVH substitution of clover hay without Galzym® (T5) and with Galzym® (T6). The crude fiber, NDF, ADF, ADL and cellulose were higher in BVH than those in clover hay while, CP% and digestible energy (Kcal/kg) were lower in BVH than those in clover hay. Results of interaction between BVH and Galzym® additives (treatment effect) had significant (P<0.05) effect on rabbits productive performance, all nutrients digestibility except EE and DCP%, blood biochemical (TP, albumin, globulin, albumin/globulin ratio, cholesterol, ALT, and urea), and cecum activity (TVFA’s and NH3). Moreover, main effect of BVH was significantly (P<0.05) improved of rabbits productive performance, nutrients digestibility (DM, OM, CP, CF, and NFE%), blood constituents (TP, albumin, globulin, and ALT), and TVFA’s in cecum. Enzyme main effect decreased (P<0.05) FI and formation of NH3 in rabbit’s cecum. In conclusion, the dietary BVH improved the productive performance of growing rabbits without negative effect on health status. Enzyme addition increases the BVH utilization and diets profitability.
