Modeling growth characteristics of meat-type guinea fowl.
This study was conducted to describe the growth pattern of the French guinea fowl, a meat-type variety. Using BW data from hatch to 9 wk, 2 nonlinear mathematical functions (Gompertz and logistic) were used to estimate growth patterns of the French guinea fowl. The French guinea fowl did not exhibit sexual dimorphism for growth characteristics. From the Gompertz model, the asymptotic BW, growth...

15 صفحه اولTestis development and daily sperm output in guinea-fowl raised under constant daily photoperiods.
The testicular growth of guinea-fowls in relation to age was compared under 3 constant photoperiods (7L: 17D; 14L: 10D; 20L: 4D) from 3 weeks of age. Although long daylength (14L or 20L) caused precocious development of the gonads, it also limited total adult gonadal weight to around 1 800 +/- 200 mg. Short daylengths (7L) delayed the development of the gonads but their adult weight was enhance...
