Evaluation of Growth Performance, Carcass Characteristics, Litter Quality and Foot Lesions of Broilers Reared under High Stocking Densities
Two repeated experiments were conducted to investigate the effects of different stocking densities onbroiler performance, carcass characteristics, litter quality and foot lesionsusing 5224 one day-old Ross 308 broilers. In each experiment, a total of 2612 one day-old broilers were allocated in 16 floor pens at densities of 16, 18, 20 and 22 birds/m2 of floor space in an environmentally controll...
متن کاملCool perches improve the growth performance and welfare status of broiler chickens reared at different stocking densities and high temperatures.
The present study investigated the interaction of stocking density and cool perch availability on broiler chickens raised at high ambient temperature (>30.8°C). Behavior, live performance, and the incidence of footpad and hock burns and abdominal plumage damage were investigated over a 4-wk experimental period. A total of 1,152 one-day-old Arbor Acres chicks were subjected to a 2 (cool perches)...
متن کاملThe Effect of Different Photoperiods and Stocking Densities on Fattening Performance, Carcass and Some Stress Parameters in Broilers
211 Effect of Photoperiods and Stocking Densities on Broilers INTRODUCTION High stocking densities and long lighting periods are two major environmental factors common to broiler production (1). The control of these factors at an optimum level not only increases commercial profitability, but also contributes to securing the supply of the human population with adequate food and animal protein. W...
متن کاملA Study on culture of Litopenaeus vannamei (preparation, water quality parameters) compared with different stocking densities using standard operational procedures
In India, the shrimp culture today has industrialized into an improved farming system and is evolved day by day into a well talented for the management. Present work was carried out in the shrimp Litopenaeus vannamei culture in Sattanathar aqua farm in the east coast of Nagai District, Tamil Nadu, India from April 2015 to August 2015. Water quality parameters for the entire culture ponds was pr...
متن کاملIncreasing dietary vitamin D3 improves the walking ability and welfare status of broiler chickens reared at high stocking densities.
A study was conducted to evaluate the effects of varying dietary vitamin D3 and stocking density on growing performance, carcass characteristics, bone biomechanical properties, and welfare responses in Ross (308) broilers. Experimental diets, containing 1, 10, or 20 times the NRC recommended level of vitamin D3 (200 IU/kg), were formulated with low, medium, or high vitamin D3 levels for 3 growi...
