Gastrointestinal development of male and female domestic canary (Serinus canaria) in the starter and grower periods

Abstract

Abstract The nutritional requirements of domestic canary (Serinus canaria) for life is determined by one of the roles of gastrointestinal organs. Thus, the evaluation of the development of canary gastrointestinal organs of males and females needs to know. The research method used was an observational survey with purposive sampling. The study used forty-eight canaries divided into two groups (twenty-four males and twenty-four females). Each group was taken a sample of six birds discontinue every month for four months. One-way ANOVA analyzed data at 95% confidence level. An Independent t-Test was used to see differences in gastrointestinal development between the two groups. A correlation test was used to determine the relationship between body weight with the development of gastrointestinal. The results showed that proventricular weight, ventricular weight, liver weight, small intestine weight, jejunum length, and ilium length for the two groups were significantly different between data collection times (P<0.05). The development of proventriculus, ventriculus, liver, small intestine, duodenum was significantly different (P<0.05) between the two groups. The growth in body weight correlates with the development of all gastrointestinal organs. Thus, it is concluded that the weight and size of the gastrointestinal organs increases with canaries age and gastrointestinal development differs between male and female groups.
