Intestinal microbiota profiles associated with low and high residual feed intake in chickens across two geographical locations
Intestinal microbe-host interactions can affect the feed efficiency (FE) of chickens. As inconsistent findings for FE-associated bacterial taxa were reported across studies, the present objective was to identify whether bacterial profiles and predicted metabolic functions that were associated with residual feed intake (RFI) and performance traits in female and male chickens were consistent acro...
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 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 کاملResidual Feed Intake and Feed Efficiency: Differences and Implications
In the beef production system, 70-75% of the total dietary energy is used for maintenance (Ferrell and Jenkins 1984; NRC 1996; Montaldo-Bermudez et al. 1990). Thus, while only 5% of the total life cycle dietary energy consumption is used for protein deposition in beef cattle, swine and poultry are more efficient at 14 and 22%, respectively. The relatively large size, slow maturity and slow repr...
متن کاملCorrelated responses in sow appetite, residual feed intake, body composition, and reproduction after divergent selection for residual feed intake in the growing pig.
Residual feed intake (RFI) has been explored as an alternative selection criterion to feed conversion ratio to capture the fraction of feed intake not explained by expected production and maintenance requirements. Selection experiments have found that low RFI in the growing pig is genetically correlated with reduced fatness and feed intake. Selection for feed conversion ratio also reduces sow a...
