This study was aimed at discovering what to use agricultural and food by-product, and investigating how to use them for monogastric animal(pigs, and poultry) feed materials. We examined effects of feeding soybean curd meal, Korean traditional brewers meal, and feed residues in stomach of unfasted finisher pigs on their productivity. And also the nutrient availability of fiber-rich materials were compared between Duroc and hybrid pigs for establishing crieterions for feed formulation. In poultry, we examined effects of re-refined soybean oil that was distilled and recovered from wasted soybean oil on egg qualities in
layers, and effects of feeding plum by-products, red-ginseng marc, and Ulva pertusa kjellman extract or powder on immunocompetence of broilers.
In results, the supplemental levels of soybean curd meal and Korean traditional brewers meal that did not negatively affect growth performance of finisher pigs were 5%, respectively. And their fermentation process by lactic acid bacteria could decrease feed/gain ratio with no significance. Nutrient values of feed residues in stomach of unfasted slaughter pigs was similar with those of conventional finisher diets. And any levels of Salmonella and mycotoxin were not detected in our samples. But for the safety issue, their use as animal feed should be further examined. Mushroom media waste had lower palatability and digestibility for both pig and poultry, but its digestibilites of crude ash, ether extract and carbohydrates were improved by fermenting and pelleting them. Recently, for its relatively lower price, palm kernel meal became very popular in feed industry. We evaluated their nutrient digestibilities in two breeds such as Duroc and hybrid pigs. Interestingly, digestibilities of crude ash, calcium and phophorus were higher in Duroc pigs than in hybrid pigs. This suggests that Duroc breed could use calcium and phosphorus of lower quality feed materials more efficiently, which was very helpful in respect to environmental pollution.
There were no negative effects of feeding re-refined wasted soybean oil to layer chicks on their egg qualities. And it was subject to replace soybean oil with them for increasing poly-unsaturated fatty acid concentration of egg yolk. In the feeding trials that supplemented plum meals and red-ginseng marc into broiler's diet under heat stresses, LPS-induced antibody production was lowered in treated group than in control group. This suggested that plum meal and red-ginseng marc could relieve LPS-induced inflammations. And in transcriptomic study of broilers fed Ulva pertusa kjellman extract as a feed additive,
the gene expression of proinflammatory cytokines in their spleens were lowered in supplemented group than control one under LPS challenge. It implied that Ulva pertusa kjellman extract could be a good candidate of feed additives for improving
immunocompetence of broilers.
