Sustainability of animal production system depends mostly on feed used. Therefore, the utilization of agricultural by product is one of the safe ways to attempt this goal. For this end, a study on the level of incorporation of cocoa pod husk on growth performance, haematological and biochemical parameters were carried out. A total of 80 young rabbits composed of 40 males and 40 females with an average weight of 824.30 ± 53.8 g and 826.09 ± 40.61g respectively. There were randomly assigned to 5 experimental rations in a complete randomized designed with 8 rabbits per treatment and each rabbit served as experimental unit. From the control ration R (0-);0% cocoa pod husks and R (0+);20% of untreated hulls, 3 other rations of which three (R1, R2, R3) were formulated with respectively 20%, 25%, and 30% husks treated with ash from bean haulms at concentrations of 12.5 kg/100 litters of water. The results revealed that the initial weight, feed consumption, feed conversion ratio, were not significantly affected (p > 0.05) by the different treatments. However, total weight gain, daily weight gains and final body weight of rabbit fed R1 ration were significantly (p 0.05) was observed in the relative weights of some parts, organs and those of the abdominal fat of the rabbits. Similarly, no significant difference (P > 0.05) was observed for haematological and biochemical parameters studied. cocoa pod husks treated at 12.5% with bean haulm ash extracts can be incorporated up to 20% - 25% to improve growth performance of rabbits witho

Cellulose, hemicellulose and lignin from cocoa pod husks were fractionated by alkali solution by using 0.5 mol/L 1.0 mol/L 1.5 mol/L concentration of NaOH for 3 hours in total. The raw materials were pretreated by 1-Cycle and 2-Cycle to obtain cellulose hemicellulose and lignin. The effects of three different concentration extraction solutions and two extraction methods on cellulose yield were compared and chemical and physical properties including water retention capacity, oil retention capacity were analyzed. In this paper, the high yield(52.8%-90.5%) of the total dietary fiber was extracted by alkali extraction. The relatively high total dietary fiber(> 50%) content of cacao pod husks indicates good dietary fiber potential. The hemicellulose(7%-15.8%) extracted in 2-Cycles was less than the hemicellulose extracted in 1-Cycle(7.6%-13.7%). The chemical and physical properties including water retention capacity and oil retention capacity were also characterized. Describe the monosaccharides composition of hemicellulose extracted by 1-Cycles. Results showed that the WRC(4.37 g-6.80 g/g) of hemicellulose increased as the concentration of the alkaline solution increased during the extraction process. Conversely, as the concentration of the alkaline solution increased, the ORC decreased(from 6.30 g to 3.76 g). Hemicellulose extracted by 1.5 mol/L NaOH showed shear thinning property, while hemicellulose extracted by 0.5 M NaOH observed more Newtonian fluid property. Methods Alkali extraction previously is shown as a promising method for the separation. 5 g of the dry mill sample was and mixed with 200 mls of three different concentrations of alkali solutions(0.5 mol/L NaOH, 1.0 mol/L NaOH and 1.5 mol/L NaOH) and stirred at 200 rpm, 50 °C. The project designed two extraction methods. 1-Cycle: extraction once. 200 ml NaOH was added in one portion, and extracted at 50 °C, 200 rpm for 3 hours, and then the next step centrifugation was carried out. 2-Cycle: extracted twice.
