EFFECTS OF ADDING ACETIC ACID AND FEED WITHDRAWAL PERIOD ON GROWTH PERFORMANCE OF BROILER CHICKENS DURING THE SUMMER SEASON

The present study evaluates the effects of feed withdrawal period and addition of acetic acid in drinking water on growth performance, physiological measurements, carcass traits, carcass chemical composition, intestinal microbial and economic efficiency of broiler chicks during the period of 22 to 42 days of age under Egyptian condition

Scholarcy highlights

  • Broiler chickens have a major share in the poultry production of Egypt
  • Long fasting periods after hatching have been shown to exert a strong influence on the performance of broilers, retarding growth rates and muscle growth, which may be due to delayed gastrointestinal maturation
  • This study was carried out at the Poultry Experimental Station, Faculty of Agriculture, Al‚ÄďAzhar University, Nasr City, Cairo, ARE This study was investigated the effect of feed withdrawal and addition of acetic acid in drinking water on growth performance, physiological measurements, carcass traits, carcass chemical composition, intestinal microbial and economic efficiency of Cobb broiler during the period from 22 to 42 days of age under Egyptian summer season condition
  • Vaccination program was applied during the experimental period; the conditions of housing and management of birds for all groups were similar during the experimental period
  • In 4, 5 and 6 weeks of age, skin temperature was significantly increased for control groups compared to the groups of feed withdrawal and the differences between and groups treated with acetic acid were insignificant
  • Supplementation acetic acids with feed withdrawal in broiler chickens diets improved growth performance, immunological status and reduced mortality rate without adverse effect on body functions, this may be due to realizing the best economic production for growing broiler chickens under the Egyptian condition
