Impact of wet feeding wheat-based diets with or without enzyme on broiler chick performance

Abstract

Scott, T. A. 2002. Impact of wet feeding wheat-based diets with or without enzyme on broiler chick performance. Can. J. Anim. Sci. 82: [409][410][411][412][413][414][415][416][417]. Two studies were conducted to determine the effect of wheat source on voluntary feed intake when diets were offered in a wet or dry form. The first experiment was designed to establish if a mould inhibitor was necessary. The second experiment allowed more extensive screening of wheat types to determine if there is a genetic component in wheat that explains the differences observed in exp. 1. Experiment 1 was based on two wheat cultivars [Hard Red Spring (HRS) and Durum]. Each wheat was ground, one portion was used as is, the other pelleted and re-ground. The four wheat sources were included at 80% of a standard bioassay diet (with enzyme) and each diet was fed with or without propionic acid. The eight diets were fed ad libitum as is or with 1.2 g water per gram of feed. The wet diets were prepared daily and all diets were fed to four groups of six male broilers from 1 to 17 d of age. The second experiment utilized three cultivars each of HRS and Durum wheat fed in similar bioassay diets with no pre-pelleting or added mould inhibitor; each diet was fed with or without enzyme. Each of the 12 diets in the second experiment was fed with and without 1.2 g water per gram of feed to six groups of eight male broilers from 1 to 21 d of age. For both experiments, the daily intake of feed, on an air-dried basis, was determined for each diet and used to calculate feed conversion for the respective feeding periods. Experiment 1 showed no effect of supplementing the wheat-based diets with propionic acid. This same experiment also clearly showed that feed intake was increased with wet feeding and there were significantly greater effects when HRS as compared to Durum wheat was fed. Experiment 2 clearly established that there are distinct differences in voluntary feed intake with wet feeding utilizing HRS as compared to Durum wheat. This experiment indicated that wet feeding mimics enzyme supplementation with regard to lowering digesta viscosity, but it is clearly unique from enzyme supplementation with its large effect on feed intake and growth. These studies support our hypothesis that variability in hydration rate of cereal-based diets may limit intake.Key words: Wheat, wet feeding, enzymes, feed intake, broilers Scott, T. A. 2002. Rendement des poulets de chair nourris de blé humide enrichi ou pas d'enzymes. Can. J. Anim. Sci. 82: 409-417. L'auteur a effectué deux expériences en vue d'établir quelle incidence le blé a sur la prise alimentaire quand on humidifie ou pas la ration. La première expérience devait indiquer s'il faut ajouter un inhibiteur de moisissures aux aliments; la seconde a permis une sélection plus précise du blé et servi à déterminer si certains paramètres génétiques expliquent les variations observées dans l'expérience antérieure. Pour la première expérience, l'auteur a utilisé deux cultivars (blé roux vitreux de printemps (R...

Effect of soaking, fermentation with lactobacillus and enzyme treatment on nitrogen‐corrected apparent metabolizable energy values of wheat in cockerels and quails

“…Scott () confirmed observations by others (Svihus et al., ; Scott and Campbell, ) that wet‐feeding wheat‐based diets mimicked the effect of supplementing the diets with a commercial xylanase enzyme, except that wet feeding substantially increased feed intake and growth rate in all wheat‐based diets and not just those with high levels of soluble NSP. Yasar and Forbes () speculated that pre‐soaking wheat‐based diets activated endogenous enzymes as well as increased the time when these enzymes were active before the feed was consumed.…”

Effects of dietary moisture content of extruded diets on physical feed quality and nutritional response in Atlantic salmon (Salmo salar)

“…Texture of the feed interfered with feed intake in pigs (Sola-Oriol et al, 2009) and chickens (Picard et al, 2000). Interestingly, dietary moisture content has an impact on feed intake and nutrient utilization of poultry (Scott, 2002) and weaning piglets (Schellingerhout, 2002) and is also important for physical quality of pellets (Gilpin et al, 2002, Lundblad et al, 2011, Moritz et al, 2001. It can therefore be hypothesized that feed moisture content can be used as a mean to adjust pellet quality of feed for Atlantic salmon.…”

Using Wet Feed in Feeding Japanese Quail Under Summer Conditions

“…In the hot climate, Dei and Bumbie, (2011) found that reducing the heat stress and then enhance feed consumption improve the growth performance. Scott (2002) and Afsharmanesh et al, (2010) found that the offered hydrated feed allowed decreasing the rates of passage of feed enhanced markedly nutrients retention. Als, Yasoar and Forbes, (2000) found that feeding in wet feed form lowed (digesta viscosity with crypt cell proliferation) and increased intestinal villus height, consequently digestion to start immediately, and may enhance the digestibility of nutrient.…”

“…Improved performance in wet feeding is attributed to a decrease in feed wastage, energy spent for eating, increased digestibility and improved palatability (Mortazavi andAfsharmanesh 2017 andFarghly et al, 2018d). The addition of water to dry feed mash before birds feeding stimulate greater intake by enhancing the feed flavor and the hydrated diet would become soluble in the gut, thereby facilitating faster digestion (Bailey 1999;Scott 2002;Farghly and Abou-Kassem 2014). These effects may be due to the changes in the physical parameters or feed forms and to allowing more fast penetration of digestive juices (Awojobi et al, 2009(Awojobi et al, , 2011.…”
