Abstract

This trial was designed to investigate the effects of corn stocking on growth performance, slaughter performance and serum cytokine content of meat geese. One thousand 2 to 3 weeks of age meat geese were randomly divided into two groups, the control group was feeding in house, the trial group was stocking in corn field which in corn jointing stage. Five geese were selected on 2, 4, 8 and 12 weeks respectively for each group, total 40 geese, weighed the weight, collected blood for the test of serum cytokine content. At the end of fattening, 12 geese which were selected randomly in well-distributed physical condition from two groups were made test for slaughter performance. The results showed that the average daily gain, dressing percentage, percentage of half-eviscerated of stocking geese were higher than that of housing geese, the content of interleukin-2 (IL-2), interleukin-6 (IL-6), interleukin-12 (IL-12), interferon-α(IFN-α) and interferon-γ (IFN-γ) of serum of stocking geese were higher than that of housing geese. The content of IL-2, IL-6 and IL-12 of serum of stocking geese and housing geese on different age had significant difference (P<0.01), the serum IL-4 content of stocking geese was significantly higher than that of stocking geese at 2 and 12 weeks (P<0.01), the serum IFN-α content of stocking geese was significantly higher than that of housing geese at 8 and 12 weeks (P<0.01), the serum IFN-γ content between the two modes had no significant difference (P>0.05). In conclusion, the corn stocking pattern can improve the growth performance and slaughter performance of geese, increase the serum cytokine content of geese, improve the immunity of geese. It is a new cultivation pattern which deserved to promote.
