Effects of Different Levels of Expanded Blood Powder on Production Performance and Meat Quality of Fatting Goose
Effects of different levels of expanded blood meal on production performance and meat quality of fatting goose was studied. Three hundred 56-day-old Huoyan geese which initial BW was 2412.85 ± 68.37 g were randomly divided into 3 groups, 5 replications each group, 20 geese each replica-tion. 1.5%, 3.0% and 4.5% expanded blood powder was added to the 3 groups, respectively. The experi-ment lasted 14 days. The results showed that compared with group Ⅰ and group Ⅲ, the average daily gain of group Ⅱ was improved by 5.15% and 8.14% (p<0.05), the feed to gain ratio (F/G) of group II was de-creased by 3.36% and 4.64% (p<0.05), the content of DM and CP in leg muscle of group II was increased by 6.02% and 8.16%, 8.08% and 11.52% (p<0.05). In addition, the content of 12 amino acids in leg mus-cle of group Ⅱ was significantly higher than group I and group Ⅲ (p<0.05), of which the content of Met, Lys and Glu was increased by 7.32% and 8.37%, 3.73% and 4.21%, 3.00% and 4.06% (p<0.05). It sug-gested that the optimal supplementation of expanded blood meal in the fatting goose diets was 3.0%. It could greatly improve production performance and meat quality of fatting goose.
