  • A total of thirty-six gilts $(24.78{\pm}1.39kg)$ were employed for 38 days (Exp. 1), and twenty-four gilts $(46.50{\pm}1.90kg)$ for 43 days (Exp. 2) to determine growth performance and carcass characteristics in pigs fed dried food waste (DFW). Pigs were allocated by dietary treatments: 0%, 20% and 40% DFW. For nutrient digestibility, twelve female pigs $(50.20{\pm}0.52kg)$ were used in individual pens to collect feces. Food wastes were collected from restaurants and apartment complex areas and dried in a drum-type dryer at $115{\pm}2{^{\circ}C}$. Experimental diets for feeding trials were formulated to contain 3,400 kcal DE/kg and 17% crude protein. The tested DFW contained 2,858 kcal DE/kg, 25.0% crude protein, 17.3% crude fat, 1.37% Ca, 1.28% P, and 3.28% NaCl. As compared to crude protein content, the limiting amino acids (i.e., 0.90% lysine and 0.52% methionine) were low. The digestibilities of energy, ash, calcium and phosphorus in the DFW were generally lower than those in the grower diets, but the digestibilities of crude protein and crude fat were higher in DFW than the grower diet. Feeding DFW in pigs had a linear (p<0.01) effect on ADG and feed/gain as the inclusion levels of DFW were increased (Exp. 1). The ADG of pigs fed 40% DFW was also poorer (p<0.05) than that fed the control diet (Exp. 2). Carcass characteristics in terms of backfat and dressing percentage were not affected by dietary treatments. In conclusion, it seems that the optimal dietary inclusion level of the DFW is about 20% in the diet for growing-finishing pigs.

  • Five type of formulated diet from agricultural by-products (ABP) were fed to four breedtype of cattle in feedlot. The ABP used are palm kernel cake (PKC), palm press fibre (PPF), palm oil mill effluent (POME), cocoa pod (COP), coffee pulp (COF) and pineapple waste (PAP). The formulated diets are PS (52% PKC, 15% PPF and 30% POME), PF (57% PKC, 20% PPF and 20% POME), PA (2% PKC and 55% PAP), CO (42% PKC and 55% COP) and CF (67% PKC and 30% COF) with 1% urea, 1% NaCl and 1% vitamins premix. The cattle breedtypes are Kedah-Kelantan (KK), Brahman-KK (BK), Hereford-KK (HK) and Sahiwal-Friesian (SF). The result showed that breedtype significantly affect all the carcass characteristic except dressing percentage. Each breedtype has it's specific carcass characteristics. HK cattle gave high marbling, BK has high % of carcass bone, KK has high % of carcass meat and low % of carcass fat (lean meat type) and SF has high % of carcass fat. Diet-type significantly affect the deposition of fat in the carcass. High moisture diets (PA and CO) produced significantly higher % carcass bone, the lowest % carcass fat and the highest % carcass meat (65.3%). PF, CF, PA and CO diets produced 63.4%, 59.9%, 55.3% and 54.1% carcass meat respectively.

  • As the world population growth and economy develops, the importance of eco-friendly organic waste resource treatment and up-cycling increases. Black soldier fly (BSF) (Hermetia illucens) treats organic waste resources that allows it to be recycled as a feed resource. In this study, we analyzed the nutrients composition, amino acid, and fatty acids of BSF larvae fed three agricultural by-products, namely apple pomace, mandarin waste, and oriental melon waste (mainly generated in South Korea). The highest BSF larvae crude protein and amino acid content was obtained in those fed mandarin waste compared with the other two diets (apple pomace and oriental melon waste). BSF larvae fed apple pomace had the highest crude fat, fatty acid, and lauric acid content compared with the other BSF larvae. Furthermore, all crude protein and fat content of BSF larvae fed the three agricultural by-products exceed that of the original agricultural by-products.

  • Animal welfare is often neglected by livestock productionists when considering the utilization of animal wastes for livestock feeds. The present review has been carried out to examine the nutritive value of poultry wastes for ruminants, the health risks involved with feeding it, the treatment and feeding methods and the production responses of animals fed on it. It was found that mineral, crude protein, crude fibre and metabolisable energy concentrations are influenced by the system of poultry production, the storage of the waste and the treatment method. Heating at $60^{\circ}C$ kills all pathogens apart from Clostidium botulinum whereas proper ensiling kills all. Apart from the kidney fat and the liver, animal tissues have not shown residues of drugs or heavy metals from poultry wastes. Palatability is affected when the moisture is more than 200 g/kg. Production responses are satisfactory when poultry wastes replace portions of concentrates. It was concluded that poultry litter generally has higher metabolisable energy contents than poultry manure, but research is needed to classify poultry litters on their energy values. The adverse effects of toxic minerals and drug residues are negligible in balanced poultry waste feeding systems.

  • Bakery waste (BW) is much cheaper than barley (20 to 40% the price of barley). Bakery waste and barley grain have similar chemical composition; they contain 99 and 97% organic matter (OM), 1.1 and 1.8% fat, 18 and 15% neutral detergent fibre (NDF) and 14.0 and 14.5% crude protein (CP), respectively (DM basis). The objectives of this study were to determine the effect of substituting BW for barley grain in high concentrate fattening diets for lambs on nutrient intake, growth and carcass characteristics. Forty Awassi lambs (21.75${\pm}$1 kg) weaned at the age of 65 days were assigned randomly to four experimental fattening diets differing in BW ratio in a completely randomized design. The control diet (CON) contained 20, 60, 11, 7, and 2% (DM basis) wheat straw, barley grain, soybean meal, corn grain, and minerals and vitamin mix, respectively. Bakery waste substituted barley grain by 10, 20 and 30% of the diet DM in the LBW, MBW and HBW diets, respectively. The experiment lasted for 56 days. Dry matter intake (DMI) decreased (p<0.05) in LBW diet compared to the CON diet by approximately 10%. No further reduction in DMI was observed with the higher substitution levels. Metabolizable energy intake for the CON diet (3.6 Mcal/d) was also reduced (p<0.05) compared with LBW, MBW and HBW diets (3.4, 3.4 and 3.3 Mcal/d, respectively). Final body weight for lambs fed the CON diet (34.8 kg) was higher (p<0.05) compared with lambs fed the LBW, MBW and HBW diets (30.6, 32.0 and 31.1 kg, respectively). Growth rate for lambs fed the CON diet (232 g/d) was also higher (p<0.05) compared to lambs fed the LBW, MBW and HBW diets (170, 189, and 167 g/d, respectively). Feed to gain ratio was higher (p<0.05) for lambs fed the LBW, MBW and HBW diets (7.2, 6.6 and 7.3, respectively) compared with lambs that consumed the CON diet (5.7). Body weight gain cost was reduced by approximately 8% by the MBW and HBW diets as compared with the CON diet. Dressing percentage, full gut weight, empty gut weight and liver weights were all unaffected by the BW addition to the diets and averaged 48.9%, 6.8 kg, 2.8 kg and 0.444 kg, respectively. However, fat tail weight was increased (p<0.05) with the higher levels of the BW inclusion. In conclusion, substituting BW for barley grain reduced DMI and growth performance. However, when BW substituted barley grain at the 20 and 30% of the diet DM, body weight gain cost was reduced by approximately 8%.

  • The effect of dehydrated food waste product (DFWP) inclusion in diets of Taiwan native chickens on the growth performance, carcass traits, clinical blood chemistry and nutrient digestibility was investigated with 320 male Taishi Native Chickens (Taishi No. 13). They were randomly allocated into four levels of DFWP inclusion (0, 5, 10, or 20%) treatment. Each treatment had 80 chickens with four replicates. At 15 weeks of age, 8 chickens were selected from each group for the nutrient digestibility trial. The results showed that body weight gain during the 0 to 4 week period decreased as the feed intake and feed conversion rate (FCR) increased linearly with increasing level of DFWP inclusion. During the 4 to 8 week period, greater body weight gains were recorded for the birds on the 5% DFWP inclusion level than for the control (p<0.05). During 8 to16 weeks, the feed intake and FCR increased linearly (p<0.05). Interestingly too, results of the carcass analysis showed that DFWP inclusion up to 20% in the diet significantly decreased the relative abdominal fat weight but increased the relative proventriculus and gizzard weights of the birds. However, other carcass parameters, meat quality and sensory scores were not significantly influenced by the dietary DFWP inclusion levels (p>0.05). Higher serum aspartate aminotransferase, ${\gamma}$-glutamyltransferase activity and crude protein digestibility, and lower gross energy digestibility were observed in the 20% DFWP group compared to the control (p<0.05). Dietary DFWP inclusion was inappropriate during the 0 to 4 week period. During 4 to 8 weeks, there was no adverse effect on chicken performance in the 20% group. There was no disadvantage on carcass properties and in the meat panel test. This result would not affect consumer determination.

  • Objective: This experiment was conducted to investigate the effects of crude glycerin from waste vegetable oil (CGWVO) on performance, carcass traits, meat quality, and muscle chemical composition. Methods: Twenty-four crossbred (Thai Native${\times}$Anglo Nubian) uncastrated male goats ($16.8{\pm}0.46kg$ body weight [BW]) were assigned to a completely randomized design and subjected to four experimental diets containing 0%, 2%, 4%, and 6% of CGWVO (63.42% of glycerol and 47.78% of crude fat) on a dry matter (DM) basis. The diets were offered ad libitum as total mixed rations twice daily. The feed intake, feeding behavior, growth performance, carcass and meat traits, and muscle chemical composition were evaluated. Results: Based on this experiment, there were significant differences (p>0.05) among groups regarding DM intake, growth performance, and carcass traits where goats receiving 6% of CGWVO had lower daily DM intake, growth performance, and carcass traits than those fed on 0%, 2%, and 4% of CGWVO. There were no effects of CGWVO on carcass length, carcass width, Longissimus muscle (LM) area, Warner-Bratzler shear force, pH and color of LM at 45 min after slaughter, as well as on other carcass cut and muscle chemical composition. Conclusion: In conclusion, the addition of up to 4% of DM in the diets for crossbred finishing goats seems to be the most interesting strategy, since it promotes greatest animal performance. Moreover, this study was a suitable approach to exploit the use of biodiesel production from waste vegetable oil for goat production.
