Industrial utilization of these crops fruits is generated some under products that can be used in breeding. The aim of this study was to test the potentialities in the breeding of cattle-cake of coconut and cattle-cake of palm kernel when they are incorporated in diets of piglet fattening. 18 piglets teamed up into three homogenous groups (three males castrate and three females) were used. The control group was fed a diet made with 55% of maize + 10% of bran maize + 25% fish powder + 4% of ash + 3% of salt. The test 1 group called diet ESSAI 1 was fed a mixture of 70% of the control diet and 30% of cattle-cake of coconut. The test 2 group called diet ESSAI 2 was fed with a mixture of 70% of the control diet and 30% of cattle-cake of palm kernel. The analysis made showed that the two cattle-cake are nutritiously rich and their incorporation in diets at degree of 30% of the total diet induced growth performance similar to that obtained with the control diet. Animals of each group were in good health and diets EASSAI 1 and ESSAI 2 were cheaper than the control diet. Then, cattle-cake of coconut and cattle-cake of palm kernel can be recommended as part of the diet of piglet (about 30%) in order to enhance profit with the same growth performance.展开更多

The co-products include copra meal, copra expellers, palm kernel meal, and palm kernel expellers. All 4 ingredients are very high in fiber and the energy value is relatively low when fed to pigs. The protein concentration is between 14 and 22 % and the protein has a low biological value and a very high Arg：Lys ratio. Digestibility of most amino acids is less than in soybean meal but close to that in corn. However, the digestibility of Lys is sometimes low due to Maillard reactions that are initiated due to overheating during drying.Copra and palm kernel ingredients contain 0.5 to 0.6 % P. Most of the P in palm kernel meal and palm kernel expellers is bound to phytate, but in copra products less than one third of the P is bound to phytate. The digestibility of P is, therefore, greater in copra meal and copra expellers than in palm kernel ingredients. Inclusion of copra meal should be less than 15 % in diets fed to weanling pigs and less than 25 % in diets for growing-finishing pigs. Palm kernel meal may be included by 15 % in diets for weanling pigs and 25 % in diets for growing and finishing pigs.Rice bran contains the pericarp and aleurone layers of brown rice that is removed before polished rice is produced.Rice bran contains approximately 25 % neutral detergent fiber and 25 to 30 % starch. Rice bran has a greater concentration of P than most other plant ingredients, but 75 to 90 % of the P is bound in phytate. Inclusion of microbial phytase in the diets is, therefore, necessary if rice bran is used. Rice bran may contain 15 to 24 % fat, but it may also have been defatted in which case the fat concentration is less than 5 %. Concentrations of digestible energy（DE） and metabolizable energy（ME） are slightly less in full fat rice bran than in corn, but defatted rice bran contains less than 75 % of the DE and ME in corn.
