“…However, enzyme treated FLPH diets had a higher (P < 0.05) CP than untreated FLPH diets. Nkosi et al (2015) also reported higher CP content on enzyme-treated diets which are consistent with the results of the current study. The CP increase could be due to the disappearance of dietary components (easily fermentable carbohydrates) during fermentation (Scholten et al, 2002;.…”

“…The reduction in fibre content (NDF and ADF) with enzyme treated fermented liquid potato hash could be attributed to hydrolysis of hemicelluloses (Muck & Kung, 1997). These results, support studies that recorded reduced fiber content with enzyme treatment (Nkosi et al, 2011(Nkosi et al, , 2015. There was no difference (P > 0.05) between treated and untreated FLPH diets on gross energy (GE) and ether extract (EE) concentrations.…”

“…The hash is produces at a rate of ±50 tons per day and is currently dumped (Nkosi & Meseke, 2010) and is polluting the environment. However, this by-product contains 150 g/kg dry matter, 105 g/kg crude protein and 58.5 g/kg crude fiber (Nkosi et al, 2015) and can be useful as pig feed. According to Charmley et al (2006) and Okine et al (2005), high moisture content of potato by-products such as potato hash is limiting the utilization of the by-products in pig nutrition.…”

“…Also, Brooks (2008), and Canibe and Jensen (2003) reported higher growth performances when pigs were fed LFF. Enzymes have been used as additives, and have been incorporated in high moisture by-products to reduce DM losses and improve nutritive value of the diet (Nkosi et al, 2015;Urriola et al, 2010). Addition of exogenous enzymes in the diet degrade fiber to fermentable water-soluble carbohydrates (WSC) for use by LAB (Eun & Beauchemin, 2007).…”

The study aimed to evaluate growth performance of grower pigs fed fermented liquid potato hash with or without exogenous enzyme. Diets containing either 200 (LFLPH) g/kg potato hash (enzyme treated or not); 400 (HFLPH) g/kg potato hash (enzyme treated or not) or no fermented potato hash (control) were formulated to provide 14 MJ/kg digestible energy (DE), 180 g/kg crude protein (CP) and 11.6 g/kg lysine. Dietary treatments were control (no FLPH), enzyme treated LFPHE and HFLPHE, and untreated LFLPH and HFLPH. The exogenous enzyme was added in treated diets to provide minimum of 560-840 TXU/TDU xylanase per kg feed, at an inclusion rate of 100 g/tonne. Diets were mixed with water at 1:2 ration and fermented for 8 hours at 25 °C room temperature before being fed to pigs. Back-slopping fermentation approach was followed to prepare diets. Twelve pigs (25±2.3 kg) per diet that were individually housed were fed ad-lib for eight weeks. Pigs were allocated to diets in complete randomized design. Average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) were measured. The enzyme treated FLPH diets had higher (P < 0.05) CP, lower (P > 0.05) NDF and ADF concentrations compared to untreated FLPH diets. The LFPHE diet had higher (P < 0.001) final weight, ADG and lower (P < 0.001) ADFI and FCR compared to LFPH, HLFPH and HLFPHE. It was concluded that LFPHE diet may be an alternative feed source for growing pigs as indicated by higher gain and lower intake compared to LFLPH, HFLPH and HFLPHE.

“…Generally, the DM content of forages influences fermentation quality of the silage; and optimal DM content ranges from 30% to 40% for good quality silage making [ 13 , 27 ]. If dry matter content is less than 20%, the fermentation process would be dominated by clostridium, resulting in low quality silage production [ 28 ]. In this study, the DM content of fresh Guinea grass and Napier grass were lower than 18%, which was not ideal to preserve the forage.…”

ObjectiveTo find out ways of improving fermentation quality of silage, the comparative analysis of fermentation characteristics and in vitro digestibility of tropical grasses silage applied with cellulases produced from Acremonium or Tricoderma species were studied in Thailand.MethodsFresh and wilted Guinea grass and Napier grass silages were prepared with cellulases from Acremonium (AC) or Trichoderma (TC) at 0.0025%, 0.005%, and 0.01% on a fresh matter (FM), and their fermentation quality, chemical composition and in vitro digestibility were analyzed.ResultsAll silages of fresh Napier grass were good quality with lower pH, butyric acid, and ammonia nitrogen, but higher lactic acid content than wilted Napier grass and Guinea grass silage. Silages treated with AC 0.01% had the best result in terms of fermentation quality. They also had higher in vitro dry matter digestibility and in vitro organic matter digestibility at 6 and 48 h after incubation than other silages. Silages treated with lower levels at 0.005% or 0.0025% of AC and all levels of TC did not improve silage fermentation.ConclusionThe AC could improve silage fermentation and in vitro degradation of Guinea grass and Napier grass silages, and the suitable addition ration is 0.01% (73.5 U) of FM for tropical silage preparation.
