“…Properly ensiled silage from high moisture by-products can replace costly feeds such as maize silage in ruminant diets (Itavo et al, 2000;Lallo et al, 2003;Pirmohammadi et al, 2006). However, ensiling of potato hash requires substantial amounts of fermentable sugars to produce sufficient lactic acid to reduce the pH and stabilize the product (McDonald, 1981;Wilkinson, 2005).…”

________________________________________________________________________________ AbstractThe aim of the study was to determine the effect of whey or molasses on the fermentation quality when added to potato hash silage. In addition, lamb performance, digestibility and feed intake of diets containing potato hash silage were compared with a diet containing maize silage (MSd). Potato hash silage (treated with no additive, or whey, or molasses) and MS were produced in 210 L drums for 90 days and the fermentation quality of the silages was determined thereafter. Diets were formulated and fed ad libitum to 32 South African Dorper lambs (23.5 ± 0.873 kg live weight) for 63 days. A digestibility study was conducted during the last week of the study. The untreated potato hash silage (UPHS) was poorly fermented as indicated by higher concentrations of butyric acid, ammonia-N and pH compared to the other silages. Higher dry matter intake (DMI) and daily weight gains (218 and 250 g/d) were obtained with MSd and molasses treated potato hash silage diet (MPHSd) compared to the other diets. Nutrient digestibility was lower in the UPHS diet compared to the other dietary treatments. It was concluded that the fermentation quality of potato hash was improved with the addition of whey and molasses. Furthermore, growth performance was higher with the MSd and MPHSd than of the other treatments, suggesting that MPHSd can safely replace MSd in a lamb diet at a dietary inclusion level of 20% without any adverse effect on animal performance. ________________________________________________________________________________

“…Also, AP is a natural source of pectic substances. [1,10,11] On the other hand, oranges contribute around 10% of the world fruit production according to the Food and Agriculture Organization of the United Nations Statistical Databases (FAOSTAT). [8] During orange juice production only approximately half of fresh orange weight is transformed into juice, while the other half is considered as production waste.…”

The potential of important agro-industrial wastes, apple pomace (AP) and orange peel (OP) as C sources, was investigated in the maximization of polygalacturonase (PG), an industrially significant enzyme, using an industrially important microorganism Aspergillus sojae. Factors such as various hydrolysis forms of the C sources (hydrolysed-AP, non-hydrolysed-AP, hydrolysed-AP + OP, non-hydrolysed-AP + OP) and N sources (ammonium sulphate and urea), and incubation time (4, 6, and 8 days) were screened. It was observed that maximum PG activity was achieved at a combination of non-hydrolysed-AP + OP and ammonium sulphate with eight days of incubation. For the pre-optimization study, ammonium sulphate concentration and the mixing ratios of AP + OP at different total C concentrations (9, 15, 21 g l −1 ) were evaluated. The optimum conditions for the maximum PG production (144.96 U ml −1 ) was found as 21 g l −1 total carbohydrate concentration totally coming from OP at 15 g l −1 ammonium sulphate concentration. On the other hand, 3:1 mixing ratio of OP + AP at 11.50 g l −1 ammonium sulphate concentration also resulted in a considerable PG activity (115.73 U ml −1 ). These results demonstrated that AP can be evaluated as an additional C source to OP for PG production, which in turn both can be alternative solutions for the elimination of the waste accumulation in the food industry with economical returns.

“…O material sólido, composto de cascas, sementes e polpa, gerado nesta etapa, é denominado bagaço de maçã. Este material possui elevada quantidade de carboidratos e fibras, constituídas de biopolímeros de alta massa molar, possui baixo conteúdo de proteínas, aminoácidos essenciais, vitaminas e sais (Albuquerque et al, 2006;Pirmohammadi et al, 2006;Sudha et al, 2007;Vendruscolo et al, 2008;Zheng & Shetty, 1998). Atualmente, este material é vendido aos agricultores da região pelo valor simbólico de U$ 1,50 t -1 para ser utilizado como adubo orgânico ou ração animal.…”

RESUMOO tratamento biológico do bagaço de maçã pelo fungo Gongronella butleri, através do processo de fermentação em estado sólido e adição deste material na alimentação de tilápias do nilo, é parte fundamental do estudo ora apresentado, razão pela qual se avaliaram a fonte de nitrogênio, a umidade inicial e a granulometria no tratamento biológico do bagaço de maçã, obtendo-se as melhores condições com uréia como fonte de nitrogênio, umidade inicial de 70% e granulometria na faixa de 0,85 a 1,68 mm, produzindo 19,63% de proteína solúvel. Os peixes submetidos a dieta contendo 30% (p p -1 ) do material tratado biologicamente na ração convencional, apresentaram aumento de 44% na massa corporal com diferenças significativas a nível de 0,05 quando comparados com os alevinos alimentados apenas com ração convencional. Palavras-chave: resíduos agroindustriais, fermentação em estado sólido, Oreochromis niloticus, Gongronella butleriBiological treatment of apple pomace and addition in diet for fish ABSTRACTThe biological treatment of the apple pomace by Gongronella butleri in solid state fermentation and the addition of this material in fish feeding (Nile tilapia) was the fundamental part of this study. The source of nitrogen, initial moisture and granulometry in the biological treatment were appraised. The best conditions being obtained with urea, initial moisture of 70% and granulometry from 0.85 to 1.68 mm, producing 19.63% of soluble protein. The fish submitted to the diet containing treated apple pomace (30% wb) presented an increase of 44% in the corporal mass presenting significant differences at the level of 0.05.
