The objectives were to conduct a genetic evaluation of residual feed intake (RFI) and adjusted for fat (RFIFat) analyse the effect selection these traits on growth, carcass reproductive traits. Data from 945 Nellore bulls in seven efficiency tests feedlot analysed. Genetic was performed using an animal model which test age at beginning considered as systematic effect. Direct additive effects random effects. Correlations gains estimated by two-trait analysis between measures (RFI RFIFat)...
ABSTRACT: The study of the genetic evaluation residual feed intake adjusted for fat (RFIFat) is important appropriate use efficiency in selection programs. objective was to analyze influence RFIF at on carcass and performance traits by estimating various parameters. Data were analyzed from five tests efficiency, which conducted with 677 Nellore males. Genetic performed Bayesian inference using an animal model via single- two-trait analyses. Variables dry matter intake, average daily gain,...
Our objective was to verify if genetic differences (i.e., additive variation) among animals classified in different residual feed intake adjusted for fat (RFIfat) groups occur, and selecting RFIfat impacts carcass traits. Ribeye area, backfat thickness, rump cap ('picanha' Brazilian Portuguese) subcutaneous marbling score were evaluated relation the high, medium low groups. Tri-trait analyses performed using animal model. The estimated values heritability high no difference found between...
This study evaluated the relationships of postpartum uterine disease, parity and body condition score (BCS) to their influence on pregnancy per artificial insemination (P/AI) at first service crossbred dairy cows. A total 588 Holstein × Gir cows from 20 farms were monitored during 35 days diagnose retained placenta, metritis clinical endometritis. Cows subjected timed AI after end voluntary waiting period. Uterine scores time AI, between 65 postpartum, grouped according size position: small...
Context There are contradictory results concerning the relationship between antral follicle count (AFC) and reproductive traits for different breeds of cattle. Understanding this could be useful to selecting animals breeding. Aims We evaluated effects AFC on parameters related in vitro embryo production (IVP), influence sexual precocity conception rate at first fixed timed artificial insemination (FTAI) Senepol females. Methods Ovarian ultrasound was performed follicles, females were...
A meta-análise permite que dados provenientes de vários estudos sejam combinados, considerando a variância existente entre os estudos. Nesse contexto, objetivou-se estimar herdabilidade (h²) combinada para peso ao nascimento (PN), à desmama (PD), ano (PA) e sobreano (PS) bovinos da raça Nelore por meio aplicação meta-análise. Foram utilizados 65 trabalhos atenderam aos critérios exigidos referem-se 215 estimativas direta as características crescimento obtidas em populações (29 PN, 74 PD, 36...
Resumo Objetivou-se avaliar em vacas leiteiras mestiças que pariram um bezerro vivo, o efeito do tipo de parto (normal ou assistido) na ocorrência desordens uterinas puerperais e no número inseminações artificiais (IA) por concepção taxa prenhez 150 dias pós-parto (DPP). As foram monitoradas durante foi classificado como normal assistido. O não precisou interferência humana, enquanto assistido auxílio para retirada via vaginal. Foram registrados 825 partos, sendo 7 natimortos (0,85%) 17...
Abstract The aim of this study was to evaluate the effect type calving (normal or assisted) on occurrence puerperal uterine disorders and number artificial inseminations (AI) per conception pregnancy rate at 150 days postpartum (PPD). Cows were observed during parturition classified as normal assisted. Normal required no human interference, while assisted a calf removal aid via vaginal access. There 825 births, 7 stillbirths (0.85%) 17 twins (2.06%). We analyzed 801 single from which 766...
