“…Cottonseed meal contains gossypol which is a polyphenolic compound that is toxic to monogastric animals, and this has lead producers to limit the presence of CSM in feeds for both poultry and pigs (Berardi and Goldblatt, 1980, Tanksley, 1990, Swiatkiewicz et al., 2016, Duodu et al., 2018). Even though the acute oral toxicity of gossypol is relatively low, if even small amounts of free gossypol are ingested over a prolonged period, it can be fatal (Berardi and Goldblatt, 1980).…”

This study was to determine the apparent ileal nitrogen (N) and amino acid digestibilities of cottonseed meal (CSM) and soybean meal (SBM) in simple carbohydrate-based and more complex wheat-based diets. Twenty five Large White × Landrace boars (40.9 kg) were randomly allocated to one of 5 dietary treatments: a wheat diet, 40% CSM in either a sugar:starch (1:1) or wheat-based diet, or 40% SBM in either a sugar:starch or wheat-based diet for 14 d. All diets contained vitamins, minerals, and contained acid-insoluble ash (AIA) and Cr2O3 as indigestible markers. Rations were offered (1,800 g/pig per d) in 3 meals/d on d 1 – 11 and 8 meals/d on d 12 – 13. On d 14, the pigs were fed hourly for 8 h. After the 8th meal, pigs were anaesthetised with isoflurothane, and ileal and faecal digesta sampled from the terminal ileum and rectum before lethal injection of barbiturate. Apparent ileal digestibility (AID) of N was greater (12.1%) when CSM was fed in the wheat-based diet as compared to the simple carbohydrate-based diet, whereas apparent ileal N digestibility of SBM was slightly lower (−4.5%) in the wheat-based diet as compared to the sugar:starch-based diet. Apparent ileal amino acid digestibility generally respondeds similarly to N. Therefore, while there was a wide difference in apparent N and amino acid digestibilities of SBM and CSM when they were fed in the sugar:starch-based diets, these differences were less apparent when they were fed the wheat-based diet. There was an apparent net release of N into the hindgut of pigs fed CSM in both base diets. Conversely, there was quite substantial apparent digestion of N in the hindgut of pigs fed SBM in both base diets. The use of Cr2O3 as an indigestible marker resulted in lower apparent ileal and faecal digestibilities than using AIA, particularly for diets containing CSM. These data demonstrate that the basal diet and choice of indigestible marker can substantially influence the estimate of apparent N digestibility, this response can differ for different protein meals.

“…The inclusions of plant ingredients in aquafeeds usually result in high levels of indigestible dietary fibre, non-starch polysaccharides (NSPs) and anti-nutritional factors (Duodu et al, 2018;Francis, Makkar, & Becker, 2001). The observed growth differences among the fish groups could be directly attributed to the differences in nutrient digestibilities.…”

“…The observed growth differences among the fish groups could be directly attributed to the differences in nutrient digestibilities. The inclusions of plant ingredients in aquafeeds usually result in high levels of indigestible dietary fibre, non-starch polysaccharides (NSPs) and anti-nutritional factors (Duodu et al, 2018;Francis, Makkar, & Becker, 2001). Most fish lack the enzymes to hydrolyse NSPs and complex dietary fibre resulting in decreased gastro-intestinal transit time for ingested feeds and leading to poor hydrolysis and reduced nutrient absorption in the gut (Bairagi, Ghosh, Sen, & Ray, 2002;Obirikorang et al, 2015d).…”

The study assessed the effect of oilseed meal mixtures on the biological value, faecal matter output, ammonia excretion rates and serum biochemistry of Nile tilapia over 63 days. The experimental diets (PPB 1, PPB 2 and PPB 3) were formulated using four selected oilseed meals that were mixed in different protein proportions to contribute 80% of total dietary crude protein. In each diet, either one or two of the oilseed meals were the dominant protein contributor. A commercial tilapia feed was used as the control diet (CTRL). Sex‐reversed Nile tilapia fingerlings (35 g) were stocked at 20 fish per tank in a recirculation system and fed at 3% body weight of their respective diets. At the end of the study, ADCs of dry matter, crude lipid and ash were significantly (p < .05) lower in all the plant‐based diets compared with the control diet. Fish fed the control diet had significantly higher weight gain and SGR compared with the plant‐based diets. Egesta output was 127% higher in the plant‐based diets compared with the control diet. All dietary treatments exhibited a similar trend in changes in ammonia nitrogen. Nevertheless, serum metabolites levels indicated no significant differences among treatments. Although the PPBs did not affect ADC of protein and serum profile, fish growth was reduced while faecal output increased.

“…Silage making reduces fibre fractions in forages owing to the activity of enzymes during fermentation (McDonald et al, 2010). Fermentation during silage production is a simple cost-effective and efficient way of improving the nutritional value of oilseed by-products (Duodu et al, 2018). Feeding pigs silage is a practice that has been carried out for years but is less common to emerging pig farmers in South Africa.…”

In this experiment, the effects were evaluated of various dietary inclusion levels of avocado oil cake (AOC) silage on growth performance, nutrient digestibility, and carcass characteristics in pigs. A mixture of 70% AOC, 25% wheat bran, and 5% sugarcane molasses was ensiled in 200 L drums for 90 days. It was then incorporated at 0%, 3% and 5% in the experimental diets. Twenty-seven Large White cross Landrace (LW x LR) weaner pigs, with an average live weight of 22 kg, were stratified by weight and randomly allocated to the three experimental diets (9 pigs/diet). Pigs were weighed individually each week throughout the trial. Daily feed intake, average daily gain (ADG) and feed conversion rates (FCRs) were recorded. A nutrient digestibility study was carried out on completion of the growth trial. At the end of the experiment, pigs were fasted for twelve hours and weighed to determine the final weight. The pigs were then slaughtered, and carcass samples were collected and analysed. The growth performance of pigs was not affected by diet, irrespective of fibre levels in the AOC silage. However, the addition of 3% AOC silage improved the digestibility of fibre fractions. The weights of the cold carcass, chops, and backfat thickness were reduced with AOC silage addition.
