Preference of Broiler Chickens for Feed Color
Studying broiler preference to feed color is important for improving comfort and welfare of broilers and it may be beneficial for improving performance. The aim of the first experiment was to examine day-old chick's preference in different light colors to different feed colors. One hundred and sixty Ross 308 newly hatched broilers, never exposed to feed, were allocated into pens illuminated ...
متن کاملVariation in feed intake of broiler chickens
With many broiler diets, particularly wheat–based diets, rate of passage of digesta limits intake and growth. In many trials, the relationship between feed intake and apparent metabolizable energy (AME) was negative or insignificant. In some trials, the limitation to voluntary intake was so severe that negative relationships existed between it and FCR. This is a consequence of the diversion of ...
متن کاملFeed Restriction in Broiler Chickens Production
The feed restriction program is on of the main techniques in growth curve manipulation for increasing production efficiency in broiler chicken. Quantities and qualitative feed restriction are procedures that can be used to manipulate the feeding strategies of poultry in order to decrease growth and metabolic rate to some extent and so alleviate the incidence of some metabolic diseases such as a...
متن کاملThe natural feed additive caprylic acid decreases Campylobacter jejuni colonization in market-aged broiler chickens.
Campylobacter causes human foodborne illness, and epidemiological evidence indicates poultry and poultry products as a significant source of human infection. Decreasing Campylobacter in the poultry intestinal tract would decrease contamination of poultry products. Caprylic acid is a medium-chain fatty acid reported to be effective in killing a variety of bacterial pathogens, including Campyloba...
متن کاملEffects of feed additives on ileal mucosa-associated microbiota composition of broiler chickens.
The effects of dietary supplementation with 2 recently developed feed additives on the composition of the mucosa-associated microbiota of the ileum were studied in growing broiler chickens. A total of 48 male 1-d-old broiler chickens of the Cobb 500 strain were distributed in 4 treatments with 2 replicates of 6 birds each. The 2 additives tested were a di-d-fructose dianhydride–enriched caramel...
