Abstract

An experiment was conducted to observe the effect of different diets containing different level ofnon-starch polysaccharides (NSP) on performance and cannibalism of laying hens. Six diets (wheatbased,rice hull-based, plant protein-based, millrun-based, MOS, and bentonite) were used and wererandomly given to 6 groups of ISA Brown hens, with 18 replicates per group and 5 birds per replicatefor 8 weeks. The results showed that diets did not have a significant effect (P>0.05) on cannibalismmortality, but numerically the rice hull diet gave the lowest effect, the millrun gave the intermediateeffect, whereas the plant protein diet gave the largest negative effect. Diet significantly affected feedintake (P<0.01), egg production (P<0.01), feed to egg ratio (P<0.01) and egg weight (P<0.05). Birds onmillrun diet had the lowest intake, but the feed to egg ratio was superior and egg production was thehighest compared to those fed other diets. In contrast, the feed to egg ratio in rice hull diet was inferior,and egg weight was also lighter than those fed other diets. In conclusion, fibre sources have beenverified as contributing factors involved in the outbreak of cannibalism in laying hens. Diets containinghigh insoluble NSP had a potential to decrease the mortality due to cannibalism.

Abstract

An experiment was conducted to observe the effect of dietary fiber given in mash form onperformance and cannibalism mortality in laying hens. Three different diets: a wheat-based diet, a guargum diet (a wheat-based diet + 20 g/kg guar gum) and a lucerne meal diet (a wheat-based diet + 40 g/kglucerne meal) in mash form were offered for 12 weeks. The results showed that birds fed guar gum diethad the lowest intake (p<0.01), egg weight (p<0.05), body weight (p<0.05) and the lowest eggproduction (p<0.01) compared to those fed other diets. Diets did not have a significant effect (p>0.05)on feed to egg ratio and cannibalism mortality, but numerically the birds fed the guar gum diet had thehighest mortality (11.3%) and the lucerne diet had the lowest (6.9%). The lack of profound differenceswas probably due to the diets were given in mash form. In conclusion, diets containing high soluble NSPreduced the performance and increased the mortality due to cannibalism in laying hens. The use of mashform may have a potential in reducing the negative effect of soluble NSP on cannibalism.

Abstract

An experiment was conducted to observe the effect of non-starch polysaccharides (NSP) onperformance and digestive activity of laying hens. Thirty-two ISA Brown hens were individually cagedand offered four diets (wheat-based, millrun-based, barley-based, and barley-enzymes diets) for 10weeks. The present experiment was assigned in a completely randomized design with 8 replicates perdietary treatment. Wheat- and barley diets caused significantly higher (P<0.05) viscosity than otherdiets. Increased viscosity caused lower digesta dry matter (DM) (P<0.01) and higher excreta moisture(P<0.05). The wheat diet did not cause a negative effect on intestinal starch digestibility, feed intake, andbird performance (P>0.05). Birds fed the barley-based diet had lower weight gain (P<0.05) and highercaecal weight (P<0.05) than those given other diets. Enzyme supplementation on barley dietssignificantly (P<0.05) reduced jejunal digesta viscosity and caecal weight, increased weight gain(P<0.05) and ileal digesta DM (P<0.01), and numerically reduced excreta moisture. The current studydemonstrated that NSP have a profound effect on digesta viscosity, performance, and digestive organs ofbirds; however, the NSP action may be modified by an interaction with each other and with other cellwallcomponents of grains in the gut. Enzyme supplementation reduced the negative effect of digestaviscosity.
