The Quality of Carcass and Meat from Geese Fed Diets with or without Soybean Meal.

ABSTRACT: The aim of the study was to compare the carcass and meat quality of geese fed with soybean meal or yellow lupin. In total, 210 White Ko?uda® geese were divided into 2 groups (1, soybean meal (SBM); 2, yellow lupin (YL), potato protein, and brewer's yeast) of 5 replications (21 birds per each). After 16 weeks, 10 geese (5 females, 5 males) from each group were slaughtered. Carcass dissection was done, and major physicochemical traits were analysed (pH, water holding capacity, drip loss, color, and chemical composition of muscles). Weight of leg muscles and their proportion in the carcass were higher (p < 0.05) in SBM. Breast muscles from SBM were characterized by increased (p < 0.05) drip loss, enhanced (p < 0.05) content of protein, water, collagen and connective tissue, and lower (p < 0.05) fat content. Leg muscles from SBM were characterized by higher (p < 0.05) protein and water content but decreased (p < 0.05) salt and fat content compared to YL. The addition of YL (approx. 28%), potato protein, and brewer's yeast had no negative effect on most meat traits and could partly replace SBM as a protein source in geese feeding. Hence, yellow lupin, potato protein and brewer's yeast can be used in geese rearing followed by fattening with oats. Some producers do not have the option of using soybean meal. Small-scale farms use their own crop resources, so lupins can be an alternative source of protein for soybean meal.

Project description:The purpose of this study was to evaluate the effects of nicotinic acid (NA) supplementation on the meat quality, carcass characteristics, lipid metabolism, and tibia parameters in Wulong geese. A total of 360 twenty-nine-day-old Wulong geese were randomly divided into 6 treatments, and each treatment included 6 pens with 10 birds per pen. Birds were fed a basal diet supplemented with 0, 20, 40, 60, 80, or 100 mg/kg NA for 12 wk. Dietary NA supplementation linearly decreased L* value and increased pH and water-holding capacity in the breast muscle (P < 0.05). Increasing NA levels linearly and quadratically decreased shear force of breast muscle (P < 0.001). Dietary NA supplementation linearly reduced the thickness of subcutaneous fat plus the skin and percentage of abdominal fat, and enhanced the width of intermuscular fat band (P < 0.001). Dietary NA addition linearly and quadratically increased intramuscular fat (IMF) content (P ≤ 0.001). Increasing NA levels decreased serum total cholesterol and low-density lipoprotein cholesterol levels and increased serum lipase activity and hepatic mRNA expression of lipoprotein lipase in a linear manner (P < 0.05). There were linear and quadratic effects in serum triglycerides and high-density lipoprotein cholesterol (HDL-C) levels and malate dehydrogenase activity with the NA addition (P < 0.05). Feeding the NA-supplemented-diets linearly increased tibia length, circumference, fat-free dry weight, and ash content (P < 0.001). There were linear and quadratic increases in Ca and P contents with the NA supplementation (P < 0.05). According to the quadratic regression analyses fitted to shear force, IMF content, serum triglycerides and HDL-C levels, and tibial Ca and P contents, the optimal dietary NA supplementation was 80 to 90 mg/kg. In conclusion, NA addition enhanced meat quality and IMF content, regulated lipid metabolism, and increased tibia quality of Wulong geese. The dosage of 80 mg/kg NA in Wulong geese aged 5 to 16 wk was recommended.
