Cut feather containing rachis as a sampling way for avian sexing
Abstract 10.1002/zoo.20083.abs Sex determination of birds is important to ensure successful breeding strategies, especially for endangered species. Most birds are vulnerable to stress during handling, however, so obtaining a sufficient amount of genomic DNA (gDNA) while causing the least amount of harm is a critical issue. Avian gender can be determined based on different CHD1 […]
Gender determination by body weight and linear measurements in American and Chilean flamingos, previously surgically sexed: Within-sex comparison to greater flamingo measurements
Abstract 10.1002/zoo.1430100506.abs Gender was determined by laparoscopic visualization of the gonads for 38 adult American flamingos (Phoenicopterus ruber ruber L.) and 36 adult Chilean flamingos (P. chilensis L.). Concomitant body weight (kg) and linear measurements (mm) of the culmen (bill), tarsus (tarsometatarsus), middle toe, and wing were taken. Statistical comparisons of body weight and linear […]
Sexing greater flamingos by weight and linear measurements
Abstract 10.1002/zoo.1430090407.abs The sex of 59 adult Greater Flamingos (Phoenicopterus ruber roseus L.) was determined by laparoscopic exam of the gonads. Concomitant body weight (kg) and linear measurements (mm) of the culmen (bill), tarsus, middle toe, and wing were taken and compared for males vs. females. Although an overlap between sexes existed in all measurements, […]
