Determination Metabolizable Energy content and nutritive value of pomegranate peel and pulp, using adult cockerels
Abstract:
The present experiment was conducted to determine metabolizable energy of pomegranate peel and pulp by adult cockerels. The pomegranate peel and pulp samples were gathered from three industries. This study had two experiments. Each experiment was done in a completely randomized design with 4 treatments and 4 replicate (1 cockerel each). The cockerels fed conventional addition method (CAM). The data were revealed that the pomegranate pulp had 91.18-93.41% dry matter (DM) 4.04-4.28 % crude proteins (CP), 1.38-1.72% ether extract (EE) and 15.48- 19.21% crude fiber (CF) and 4.62% ash. The apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), true metabolizable energy (TME) and nitrogen-corrected true metabolizable energy of pomegranate peel were 2219.84-2443.21, 2201.09-2424.13, 2250.13-2482.69, and 2249.56, 2481.56 kcal/kg, respectively. The pomegranate pulp had 91.07-92.63% DM, 10.21-11.80% CP, 9.72-10.83% EE and 31.51-35.94% CF. The apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), true metabolizable energy (TME) and nitrogen-corrected true metabolizable energy of pomegranate pulp were 2357.71-2581, 2355.83-2579.2, 2452.62-2642.93 and 2451.11 -2641.52 kcal/kg, respectively. The estimated AMEn of pomegranate pulp and peel based on prediction equation were 2419.19-2540.8, 2166.02-2533.67 kcal/kg. The best eqution for estimating of AMEn were Nascimento, AMEn = 2707.71 5.863EE− 1.606aNDFom. It is concluded that the pomegranate pulp may had a good feed to use in poultry diet, but the manager may be consider the tannin and other anti-nutrition factor in pomegranate.
