Green Forage Affect Fattening And Fat Deposition In Wanxi White Goose

Feed composition affects fat deposition in animals.Goose poultry feed as herbivores,cy feed ratio influence of goose fat deposition,due to the lack of standard goose feed nutrition standards,which led to the current process of feed material proportion of fattening geese by no standard.To this end,the same batch of young Wanxi White Geese in the same feeding condition concentrate were raised to 70 days of age,select the similar weight of 240 geese,half male and half female,were randomly divided into 4 groups,with3 replications per group,20 chickens in each replicate.Green feed and concentrate group 1to group 4 were fed with concentrate,concentrate,concentrate feed add dry matter content of 15% add dry matter content of 30% add dry forage substance content of 45%,finishing30 days,a comparative analysis of green feed additive on the subject refers to the influence of goose fattening and carcass weight the performance and blood lipid.Body weight of male geese at 80 d of age increased significantly with the proportion of green forage addition(P=0.016).Body weight of female geese at 80 d of age first increased and then decreased(P=0.039).Geese fed 30% green forage exhibited highest body weight.Body weight in geese at 90 and 100 d of age were not affected by green forage addition.Serum lipids VLDL,HDL,FFA,and CM content decreased with the green forage addition.Green forage exhibited no significant affection on serum lipid content among groups,and the fattening time and green forage interaction also exhibited no significant effects on serum lipid content in Wanxi White goose.No significant correlation was observed between serum lipd and IMF content.The semi-eviserate,eviscerate,breast percentage,and liver percentage were not affected by green forage addition in Wanxi White geese.However,leg percentage decreased with the green forage addition.Leg percentage and liver percentage exhibited higher in female geese as compared to male geese(P=0.0004).In summary,green forage addition affected body weight of Wanxi White Goose at 80 d of age.Adding 15-30% green fodder is helpful to improve fattening effect,Thirty percent of green forage exhibited highest body weight.Serum VLDL,HDL,FFA and CM content was affected by fattening time.No significant correlation between IMF content and serum lipid was observed.Green forage addition decreased leg muscle percentage in Wanxi White Goose.
