Abstract:

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 controlled broiler house. Data collected from the two experiments were pooled together for statistical analysis. The results indicated that body weight gain significantly decreased with increasing stocking density (P

Effects of stocking density on growth performance, carcass traits, and foot pad lesions of White Pekin ducks.

Two experiments were conducted to study the effects of stocking density on growth performance, carcass yield, and foot pad lesions of White Pekin ducks from hatch to 14 d of age (experiment 1) and from 14 to 42 d of age (experiment 2), respectively. All ducks were reared in raised plastic wire-floor pens with a pen size of 30 m(2), and males and females were mixed at a ratio of 1:1 in each pen ...

Cool 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)...

Growth performance, carcass quality, and noncarcass components of indigenous Caribbean goats under varying nutritional densities.

Studies were conducted to determine the effects of feeding regimens on growth and carcass quality of the Creole goat, a genotype indigenous to the Caribbean. Forty kids weighing 9.0 +/- 1.2 kg of BW were reared indoors after weaning. Four supplement amounts were compared (10 kids per treatment): the G0 group received the basal diet (tropical forage, 8.8 MJ of ME and 108 g of CP/kg of DM) withou...

The 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...

Evaluation of mango saponin in broilers: effects on growth performance, carcass characteristics, meat quality and plasma biochemical indices

OBJECTIVE The objective of the present study was to determine whether mango saponin (MS) could be used as a feed additive in broiler chicks by evaluating growth performance, carcass characteristics, meat quality, and plasma biochemical indices. METHODS A total of 216 1-d-old Arbor Acres male broiler chicks were randomly assigned into three dietary treatments supplemented with 0 (control), 0.1...

Effect of different stocking densities on hematological parameters and growth performance of great sturgeon (Huso huso)

A 5 weeks study was conducted to determine the effects of different stocking density on hematological parameters of great sturgeon. Fish were cultured in duplicates of fiberglass tanks under stocking densities of 50, 75, 100 and 125 fish/m3 as T1, T2, T3 and T4 respectively. Based on the results significant increase (p<0.05) in total body weight and total length were related to low density grou...
