Precocidade sexual em bovinos Nelore avaliada por ultrassonografia testicular

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2014
The present study aimed to evaluate if there are differences in testicular parenchyma echogenicity between pre-pubescent and pubescent animals at the same age. Ultrasound examinations were performed in longitudinal and transversal planes of the testicles

Genetic Parameters for Novel Feedlot Profitability‐Related Traits in Nelore Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT This study aimed to estimate (co)variance components and genetic parameters for accumulated profitability (AFP) and profit per kilogram of liveweight gain (PFT), and their relationships with weight at 450 days of age (W450), scrotal circumference at 365 days of age (SC365), age at first calving (AFC), probability of precocious calving at 30 ...

Impact of Model Parameterisation and Variance Component Estimates on Genomic Predictions of Carcass Traits in Montana Composite Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT This study evaluated the influence of variance component (VC) estimates, obtained from different models and two relationship matrices, pedigree‐based (BLUP) and genomic information‐based (ssGBLUP), on genomic predictions of carcass traits in Montana composite cattle.

Genomic Prediction Ability Using Linear and Threshold Approaches for Different Stayability Definitions in Nellore Females

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Enhancing female longevity through regular calvings improves herd replacement rates and reduces the costs associated with replacing low reproductive efficiency animals. Stayability (STAY), defined as a cow's ability to remain productive in the herd, is a categorical trait that challenges traditional genetic evaluation due to its non‐normal ...

Contribution of Fat Adjustment to Residual Feed Intake Estimation in Beef Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Including fat thickness as a covariate in the regression model used to calculate residual feed intake (RFI) could help preserve carcass quality traits, such as marbling, flavour and juiciness, by accounting for variation in fat deposition.

Mother-infant relationship in the slender loris (Loris tardigradus lydekkerianus) [PDF]

, 1980
Close observations under caged conditions were made on the behaviour of four mother lorises towards their own and alien infants. There appears to be no mutual recognition between the mother and her infant, and the relationship appears to be less specific.

Genetic Parameters and Genome‐Wide Association Studies for Fertility and Reproduction Traits in U.S. Katahdin Sheep Based on the Single‐Step GBLUP Methodology

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Sheep production contributes to a secure and diverse food and fibre supply in the United States, with growing ethnic diversity strengthening demand. Katahdin is a composite hair‐type sheep breed developed in the United States that has become the most popular breed in many regions of the country and the first one to have genomic selection ...

Do the biological characteristics of trout (Salmo trutta) smolts influence their spring migration timing and maiden marine sojourn duration?

Journal of Fish Biology, EarlyView.
Abstract Anadromous salmonids migrate seaward to exploit feeding and growth opportunities in marine habitats, yet how smolt biological characteristics influence their marine migratory behavior remains poorly understood. This study used 9 years of trout (Salmo trutta) population monitoring data from 15,595 tagged age‐0+ parr, 1033 smolts detected ...
