The objective of the present study was to evaluate the effect of nutritional management treatments during the rearing period on the performance and carcass traits of Hereford steers finished either on pasture or in feedlot. Two hundred and forty male Hereford calves, weaned at 8 months of age with an average weight of 17017 kg, were used. After weaning, four nutritional treatments were imposed on the calves so as to obtain different daily liveweight gains (LWGs, kg/day) during the first winter (winter-growth phase). The nutritional management groups were high LWG in feedlot (HF), low LWG in feedlot (LF), high LWG on pasture (HP) and low LWG on pasture (LP). Finishing phase began when each group reached a mean liveweight (LW) of 35028 kg. During this phase, one half of the HF, LF,HPand LP animals were finished on pasture and the other half in feedlot. The animals were slaughtered when each group attained a meanLWof 500 kg. The carcass traits ribeye area (cm2) and backfat thickness (mm) were measured by ultrasonography. Liveweight, LWG and ultrasonography records were analysed by repeated-measures analysis.DMintake as a percentage ofLWand feed conversion ratio (FCR; kg DM/kg LW) during feedlot were analysed by ANOVA. Least-square means for LWGs of pasture-finished animals were
0.807, 0.799, 0.819c and 0.782 kg/day for HF, LF, HP and LP respectively. Least-square means forLWGof feedlot-finished animals were 1.569, 1.554, 1.484 and 1.431 kg/day for HF, LF, HP and LP respectively. Least-square means for FCR in feedlot were 7.12, 7.20, 7.97 and 8.92 for HF, LF, HP and LP respectively. Hot carcass weight had a similar trend as did LWG. Feedlot-finished animals attained heavier hot carcass weights once they received a better nutritional management during the first winter. The growth-group management did not affect (P> 0.05) dressing percentage. The carcasses of feedlotfinished animals showed higher (P < 0.05) dressing percentages than did carcasses of pasture-finished animals. Nutritional feeding management during thefirst winter had permanent effects on growth, carcass andFCRtraits; however, the prevalence of these effects depended on the feeding system during the finishing phase. On the basis of the results obtained in the study, it is recommended that animals receive an adequate nutritional management during the first winter so as to maximise their future performance, especially for intensive beef-cattle growing?finishing systems. However, if the animals have been subjected to restriction during early growth, they should be finished under pasture conditions.

ABSTRACT.
The aim of this study was to estimate variance components and to identify genomic regions and pathways associated with maternal related traits in Santa Inês sheep breed adapted to tropical climate. Phenotypic records for maternal efficiency (ME), metabolic maternal efficiency (MME), twin lambing (TL), adult weight (AW), metabolic adult weight (MAW), and body condition score (BCS) from 1,333 ewes from Santa Inês breed were used. A total of 576 animals were genotyped with the Ovine SNP12k BeadChip (Illumina, Inc.), that contains 12,785 bialleleic SNP markers. The variance components were estimated using a single trait animal model by single step genomic BLUP procedure. For AW, MAW, BCS, ME, MME and TL the mean values were 50.30 (±9.76), 19.2 (±2.33), 2.76 (±0.72), 34.6 (±15.95), 91.8 (±42.52), and 1.27 (±0.44) respectively. The heritabilities estimated were moderate for AW (0.32) and MAW (0.33) and low for BCS (0.04), ME (0.07), MME (0.08), and TL (0.10). A total of 7, 8, 13, 16, 19, and 09 candidate regions for ME, MME, TL, AW, MAW and BCS traits were identified respectively. AW and MAW had a total of 15 regions in common, while AW and BCS had a common region on chromosome 21. ME and MME had six candidate regions in common, and TL had no common regions with any other features. The maternal indicator traits have genetic variability to respond to selection in Santa Inês breed, and it would be expected higher genetic gain for ewe adult weight when compared to the others studied traits. Several candidate regions related to growth, reproduction, lactation and enviromental adaptability were identified in this study. These candidate regions would give support to identify and select animals with higher maternal efficiency and fitness, and consequently, increase the productivity of Santa Inês sheep. Moreover, the results of this study should help to understand the genetic and physiologic mechanism associated with maternal related traits in Santa Inês breed.
