|Title:||Gross response and meat yield of broiler chickens fed different levels of digestible methionine||Contributor(s):||Amin, Jahanur Rahman (author); Mercier, Yves (author); Iji, Paul (author)||Publication Date:||2013||Handle Link:||https://hdl.handle.net/1959.11/14508||Abstract:||The current focus of genetic selection of broiler lines is on cut part yield. There is therefore a need to ascertain the methionine requirements to increase such yield. Three hundred and twenty male broiler chicks were randomly assigned to four dietary groups (digestible methionine levels) - 4.0, 5.8, 6.7 and 7.6 g/kg; 3.5, 5.1, 6.0 and 6.8g/kg , and 3.2, 4.6, 5.4 and 6.1 g/kg in the starter, grower and finisher diets, respectively. There was no significant effect of digestible methionine levels on growth response. However, breast meat yield was improved (P < 0.014) by increasing digestible methionine levels up to 6.7, 6.0 and 5.4 g/kg in the starter, grower and finisher stages. There were also improvements in weight of thighs (P < 0.012), drumsticks (P < 0.001) and wings (P < 0.013) with increased levels of digestible methionine. The results suggest that increasing digestible methionine levels could improve meat yield without altering the growth response of broiler chickens.||Publication Type:||Conference Publication||Conference Name:||ESPN 2013: 19th European Symposium on Poultry Nutrition, Potsdam, Germany, 26th - 29th August, 2013||Source of Publication:||Proceedings of the 19th European Symposium on Poultry Nutrition, p. 151-151||Publisher:||German Branch of WPSA: World's Poultry Science Association||Place of Publication:||Potsdam, Germany||Field of Research (FOR):||070204 Animal Nutrition||HERDC Category Description:||E3 Extract of Scholarly Conference Publication||Statistics to Oct 2018:||Visitors: 521
