Nutritional and physical characteristics of commercial hand-feeding formulas for parrots

Hand-rearing is a common practice for the propagation of psittacines, however, research on their nutrition is limited and the neonatal requirements are not well understood. We analyzed the nutrient composition and physical characteristics of 15 commercially available parrot handfeeding formulas. Formulas were compared with the average nutritional content of the crops of free living Scarlet Macaw (Ara macao) chicks. When the formulas were prepared...

Growth curves and their implications in hand-rearing monk parrots (Myiopsitta monachus)

Monk parrots (Myiopsitta monachus) were hand-reared over two chick seasons spanning from 2010-2011. Information on the growth curve of chicks hand-raised in 2010 was used to develop a feeding protocol for the 2011 season. This protocol was focused to address the problem areas of delayed growth and then excessive growth experienced by the baby parrots hand-reared in 2010. The 2011...

Comparative protein requirements of three species of parrots with distinct dietary specializations

Highly specialized nectarivorous and frugivorous birds have overcome the constraints of low dietary protein levels. Proposed physiological mechanisms that enable such specialists to subsist on low-protein diets include low protein requirements, low endogenous protein losses, high feed intake, and high protein digestibilities. These traits were compared among nectarivorous red lories (Eos bornea), frugivorous Pesquet’s parrots (Psittrichas fulgidus), and granivorous budgerigars...

Nutritional requirements of adult palm cockatoos

The nutrition section is based on a questionnaire that was distributed in 1992 to facilities that have bred or displayed palm cockatoos, on general knowledge of the nutritional requirements of birds (in particular successful diets and practices with psittacines), and on what has been observed with palm cockatoos at ABRC over the years.
