Growth is a key characteristic of animals and can be defined as any change in body size per
time unit, and is influenced by genotype and environment. Mathematical functions called …

Abstract The four-parameter Unified Richards model has been applied to the growth of
different animal taxa. Traditionally researchers of animal growth have favoured three …

OBJECTIVE While there is a long history of interest in measuring brain growth, as of yet
there is no definitive model for normative human brain volume growth. The goal of this study …

Poultry is subject to varying degrees of feather loss and feather pecking during production,
which seriously affects the live appearance and carcass appearance of their commercial …

Feathers play a critical role in thermoregulation and directly influence poultry production.
Poor feathering adversely affects living appearance and carcass quality, thus reducing …

This study compared four nonlinear models to describe growth parameters of broiler chicken
fed on different levels of corn bran. Two experiments were designed for this purpose. In the …

It has been hypothesised that, for post-hatching domestic birds reared under good
conditions, the relative growth rate R=(dW/dt)/W= dlnW/dt is a linear function of lnW; W is …
