Genetic parameters for production and feeding behaviour traits in crossbred steers fed a finishing diet at different agesDownload
Because cattle can be raised postweaning under several feeding regimes, this study examined the consistency of phenotypic and genetic parameters of some production and feeding behaviour traits between two feeding periods that beef cattle received a finisher diet. Crossbred steers (n=851) were...
Genetics of feed efficiency and feeding behavior in crossbred beef steers with emphasis on genotype-by-environment interactionsDownload
This study examined whether crossbred steers had different production, feed efficiency and feeding behavior performances when they were fed a grower or finisher diet or both, in successive feeding periods. Major feed efficiency traits were residual feed intake (RFI) and gain to feed ratio (G:F)...
Goldfish ghrelin: Molecular characterization of the complementary deoxyribonucleic acid, partial gene structure and evidence for its stimulatory role in food intakeDownload
Complementary deoxyribonucleic acid (cDNA) encoding goldfish preproghrelin was identified using rapid amplification of the cDNA ends (RACE) and reverse transcription (RT)-polymerase chain reaction (PCR). The 490 bp cDNA encodes a 103 amino acid preproghrelin which has a 26 amino acid signal...
Residual feed intake adjusted for backfat thickness and feeding frequency is independent of fertility in beef heifersDownload
This study examined the effects of residual feed intake (RFI), RFI adjusted for off-test backfat thickness (RFIfat) and RFI adjusted for off-test backfat thickness and feeding event frequency (RFIfat & activity) on heifer fertility and productivity. Beef heifers (n=190) were monitored for...
