Time-Budgets of Turkeys (Maleagris gallopavo) Reared Under Confinement and Free Range Rearing Systems

چکیده
Time budget of turkeys (Maleagris gallopavo) reared under free-range and confinement rearing systems was recorded and compared from day old chick to sixth months of age. Throughout the study period, M. gallopavo reared under free-range rearing system spent relatively greater time in litter pecking (23.51%) followed by walking (19.99%), feeding (16.33%), preening (13.72%), feather pecking (6.07%), aggression (5.94%), drinking (5.90%), immobility (2.36%), standing (2.29%) and jumping (1.96%). Similarly, the birds reared under confinement rearing system spent relatively greater time in lying (17.82%) followed by litter pecking (15.71), preening (12.93%), walking (11.47%), standing (8.35%), drinking (8.31%), aggression (6.85%), feeding (6.46%), feather pecking (6.04%), immobility (4.59%) and jumping (1.46%) behavior. It was observed during present study that the birds reared under free-range rearing system spent significantly greater time in litter pecking, walking and feeding behaviors as compared to the birds reared under confinements. These behaviors are indicators of good health of the animals, therefore free-range system is recommended over confinement rearing system for farming of M. gallopavo.

An experiment was conducted to determine the effect of range and confinement rearing on behavior and tonic immobility of four genetic lines of turkeys. Lines of turkeys utilized were selected for increased body weight, or increased shank diameter, or were randombred control lines developed in 1966 and 1986. Birds from the four lines were brooded lines and sexes intermingled to 8 wk of age in co...

Line by environment interactions complicate interpretation of results from long-term selection experiments. To investigate the potential effects of such interactions, a study was conducted in which birds from four genetic lines were reared in two environments. Birds from four turkey lines were brooded in confinement housing. At 8 wk of age, half of the birds from each full-sib family were moved...
