The sequential feeding of growing chickens.
1. Male chickens, I week old, were fed alternately for 6 or 12 h periods with diets complementary in their amino acid composition. The isonitrogenous, isoenergetic diets were based on fish meal or sunflower meal as the sole source of protein, or fish meal-sunflower (40:60, w/w); each diet contained 120 g crude protein/kg. Other groups of chickens were given these diets ad lib. 2. Net protein ut...
متن کاملPerformance, Carcass Characteristics and Immune Responses of Broiler Chickens Subjected to Sequential or Wet Feeding Programs Subsequent to Early Meal Feeding Regime
The current study was conducted to evaluate effects of sequential or wet feeding programs subsequent to and early meal feeding regime on performance, carcass characteristics and humoral immunity in broiler chicks. 192 Ross 308 chicks (seven-day old) were allocated to four treatments at four replicates (12 chicks per plot) based on a Completely Randomized Design. Treatments were included: contro...
متن کاملThe feeding dynamics of broiler chickens.
Contrary to a commonly held belief that broiler chickens need more space, there is increasing evidence that these birds are attracted to other birds. Indeed, commercially farmed birds exhibit a range of socially facilitated behaviours, such as increased feeding and preening in response to the presence of other birds. Social facilitation can generate feedback loops, whereby the adoption of a par...
متن کاملSequential feeding with variations in energy and protein levels improves gait score in meat-type chickens.
Feeding broilers by alternating different diets for 1 or 2 days is known as sequential feeding, and it possibly reduces leg problems since it slows down early growth and may enhance general activity. The present study compared continuous feeding with a standard diet (C: metabolisable energy = 12.55 MJ/kg, crude protein = 190 g/kg) with alternations of a high-energy/low-protein diet (E+P-:+7% ME...
متن کاملSequential feeding programs for broiler chickens: twenty-four- and forty-eight-hour cycles.
Sequential feeding programs (Seq) of 2 feeds, 1 protein rich-energy poor and 1 energy rich-protein poor, during the same day or every other day were compared with a control complete diet for male broiler growth and body composition from 15 d to market weight. In experiment 1, BW gain and breast meat yield were significantly lower than those of controls for 24-h-cycle Seq with extreme protein co...
