  Owing to the beneficial effects of a carotenoid called lycopene in tomatoes, the present work was undertaken to study the effect of dietary unboiled (UT) and boiled tomato (BT) waste in broiler chicken on performance, internal organ development and serum lipid profile. One hundred fifty Arbor Acress strain broiler chicken of one week age were used for the study. The experiment was performed in a completely randomized design with different combination of UT and BT (0% UT: 0% BT; 25% UT: 75% BT; 50% UT: 50% BT; 75% UT: 25% BT; 100% UB and 100% BT) to completely replace rice-bran and altering the levels of yellow corn and coconut oil in diet. Each treatment was repeated five times. The results revealed that feed consumption, daily weight gain and feed conversion of broiler chicken were not significantly (p>0.05) affected by various dietary combinations of UT and BT waste. The weights of said internal organs of broiler chicken did not vary significantly (p>0.05) by various combination of dietary UT and BT waste. Further, except for HDL, there was a significant (p<0.05) effect on serum total cholesterol, LDL and triglyseride values of broiler chicken fed different combinations of UT and BT waste in diet. In conclusion, boiled tomato waste up to 7% level in the diet of broiler chicken is highly effective in regulation of lipid metabolism in a positive manner and could prove as an important tool for health conscious people in the prevention of atherosclerosis or coronary heart diseases.

  Objective: An experiment had been conducted to study the effects of boiled tomato waste utilization in the diet on the serum lipid profile: total cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL) and the egg quality (egg yolk cholesterol, egg yolk lipid and egg yolk color index) of 200 Isa Brown laying-hens of 60 weeks-old fed diet containing boiled tomato waste powder and to determine the appropriate level of boiled tomato waste in the diet. Materials and Methods: The experiment was performed in a completely randomized design with five different levels of boiled tomato waste powder in diets (0, 3, 6, 9 and 12%) as treatments and each treatment was replicated four times. Measured variables were total cholesterol, LDL and HDL of blood serum and total cholesterol, fat contents of egg yolk as well as egg yolk color index of laying-hens. Results: The experiment showed that the total cholesterol, LDL and HDL of laying-hen’s blood serum and fat content of egg yolk was not affected (p>0.05) by different levels of boiled tomato waste powder in diets, while the egg yolk total cholesterol and egg yolk color index were significantly influenced (p<0.05). The increase in the level of boiled tomato waste powder in the diet reduced the total cholesterol in egg yolk but increased the egg yolk color index. Conclusion: The inclusion of 12% boiled tomato waste powder in laying-hen’s diet was the best level for lowering egg yolk total cholesterol and improving egg yolk color index.

  Background and Objective: Areca catechu L. is an herbal plant that contains polyphenol (flavonoids and tannin) and alkaloid (arecholine, arecolidine, guvacoline, guvacine and isoguvacine) compounds. Both polyphenols and alkaloids are known to be anthelmintic as well as antibacterial, antifungal, anti-inflammatory, antioxidant and cholesterol lowering compounds for poultry and dogs. When Areca catechu L. seeds are harvested, they produce 76% Areca catechu L. peel waste, which can be potentially used as a poultry feed additive to increase poultry performance. Areca catechu L. peel waste contains as much as 1.693% total polyphenols, 1.383% total alkaloids, 1.466% catechins and 456.59 mg/100 g tannins. The utilization of Areca catechu L. peel waste as a poultry feed additive is limited due to the high crude fiber content, which can be as high as 47.02%; the poultry digestive tract does not produce cellulase to hydrolyze crude fiber. The fermentation of Areca catechu peel waste with a local microorganism solution that produces cellulase is one solution for lowering crude fiber in Areca catechu L. peel waste. This experiment was performed to select the best local microorganism solution from different sources as a crude fiber digester in Areca catechu peel waste to produce poultry feed additives. Materials and Methods: This experiment was performed with a completely randomized design using five different sources of local microorganism solutions derived from bamboo sprouts, banana corms, mixed fruit waste, mixed vegetable waste and rice waste. As much as 500 mL of each local microorganism solution was used to ferment 200 g of Areca catechu L. peel waste for 2 weeks and each treatment was repeated four times. Crude fiber and dry matter were the parameters in this experiment and the total number of colonies of bacteria and fungi was calculated before and after fermentation with each local microorganism solution. Results: The fermentation of Areca catechu L. peel waste with different sources of local microorganism solutions significantly lowered crude fiber and dry matter (p<0.05) and the total number of colonies of bacteria and fungi decreased after the fermentation process, except for the colony of bacteria and fungi in the local microorganism solution from bamboo sprouts, which increased. Conclusion: Mixed vegetable waste was the best source of local microorganism solutions for lowering crude fiber in Areca catechu L. peel waste and the crude fiber decreased from 47.02-25.95%.
