Parakeets (Melopsittacus undulates) are classified parrot order Psittaciformes. Parakeets are monomorphic birds whose sex is difficult to be distinguished. Sex identification is very important for breeding efforts in order to increase the parakeet population. External morphology was determined to identify the sex of the birds. This research was conducted to determine the sex of parakeets (male and female). This study used five male and five female parakeets aged 4 months as the study objects. This study used the quantitative and qualitative method. Results of this study was verified by performing surgery to determine the sex of parakeet based on their reproductive organs. The t-test results of morphometric characteristics showed no significant different in the length of body, upper bill, lower bill, wing, tail, femur, tibial-tarsus, tarsometatarsus and digits as well as the body weight between male and female parakeets. The color of the cere was useful to accurately determine sex in parakeets (blue in males and white in females). This research provided information to the public about the differences between male and female parakeets for the selection of good broodstock in order to increase their population in captivity.
Turmeric powder supplements contain curcumin and essential oils that can increase parakeet production. The aims study to analyze effect supplementation turmeric powder (Curcuma longa L.) on duodenal female parakeets (Melopsittacus undulates). This research used ten female parakeets aged four months. Research used a randomized design complete with two treatments and five replications. The treatment was P1 as control and P2 with supplement turmeric powder dose 35 mg/bird/day for 30 days. The result using t-test showed that effect turmeric powder did not make significant (p> 0.05) on body weight, feed consumption, gastrointestinal length, and duodenal histomorphometry (villi height, villi width, crypt depth, and mucosal muscular thickness). The conclusion is supplementation turmeric powder on female parakeets (Melopsittacus undulates) not effect on body weight, feed consumption, gastrointestinal length, and duodenal histomorphometry (villi height, villi width, crypt depth, and mucosal muscular thickness). Supplementation turmeric powder dose 35 mg/bird/day not positive impact on the digestive system of parakeets.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
