Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

Acta Zoologica, EarlyView.
ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.

Estrous characterization in cross-bred heifers (Bos taurus indicus x Bos taurus taurus) by radiotelemetry

, 2006
O jerked beef é oficialmente descrito como carne bovina salgada, curada e dessecada. Os parâmetros físico-químicos utilizados na determinação do seu padrão oficial de identidade e qualidade são a atividade de água e os teores de umidade, matéria mineral (ou cinzas) e nitrito residual.

Assessing soil and native high Andean grassland quality under grazing: A case study from the wet Puna of Peru

Grassland Science, EarlyView.
Abstract High Andean grasslands are vulnerable to changes in their nutritional quality and carbon sequestration capacity, especially in grazing systems. This study evaluated soil quality and native grasses by measuring carbon, physicochemical parameters, and the nutritional quality of predominant species in the wet Puna of Junín, Peru.

Blood parameters of Angus and Nellore young bulls fed diets with or without forage.

Revista Brasileira de Zootecnia
We evaluated blood parameters of Angus and Nellore bulls fed diets with and without forage. Forty animals with initial body weight (BW) of 380±16.2 kg were housed in individual stalls.

Expressão de genes ligados à maciez da carne em bovinos da raça Nelore. [PDF]

, 2015
Dentre as características da carne, a maciez é a mais desejada pelo consumidor. Bovinos de origem Bos taurus indicus são conhecidos por produzirem carne de menor maciez quando comparado às raças de origem taurina.

Reproductive consequences of mate retention and divorce in a short‐lived migratory passerine

Ibis, EarlyView.
In socially monogamous birds, pair‐bond duration varies across species, from single‐breeding associations to long‐lasting, multi‐year bonds. Studies of pair retention and divorce have focused on long‐lived and sedentary species rather than short‐lived and migratory species.

Genomic Analysis of Inbreeding Depression on Productive Traits in Rubia Galega Beef Cattle Breed

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In autochthonous livestock breeds with small populations, such as the Rubia Galega from Galicia (Spain), mating between relatives is common and can lead to inbreeding depression. Genomic inbreeding coefficients were estimated for 4984 animals using ~63,000 SNPs to assess inbreeding depression in four key traits: age at first calving (AFC) with

Genetic Parameters of Methane Emission, Feed Efficiency, Feeding Behaviour, and Growth Traits in Beef Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus , especially Nellore cattle, remain limited.

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.
