Production Performance of Hubbard Broilers with Different Stocking Densities under Hot Climatic Conditions of Pakistan.
ABSTRACT: The experiment was conducted to investigate the effect of four stocking densities on the production performance i.e. weight gain, feed consumption, feed conversion ratio (FCR) and mortality of Hubbard broilers chicks under hot climate. The ambient temperature 35ºC to 45ºC caused the increase in actual experimental house temperature irrespective of set point house temperature, as naturally ventilated open sided house with extraction fans was used for the experiment. Four of the stocking density treatments; 10 birds/m², 12 birds/m², 9 birds/m² and 8 birds/m² were provided to the four groups A, B, C and D, respectively. The experiment was conducted for 2 to 6 week of age of the birds (7 days adaptation period and 35 days experimental period). Water and feed were provided ad libitum. Twenty-three hours light was provided. Weight gain per bird (2-6 weeks) of groups A, B, C and D was...
