Different combinations of monensin and narasin on growth performance, carcass traits, and ruminal fermentation characteristics of finishing beef cattle

Frontiers in Veterinary Science, 2023
The objective of this study was to evaluate the effects of different combinations of monensin and narasin on finishing cattle. In Exp. 1, 40 rumen-cannulated Nellore steers [initial body weight (BW) = 231 ± 3.64 kg] were blocked by initial BW and ...

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 ...

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.

Freeze‐dried Lactobacillus spp. improved average daily liveweight gain and reduced methane intensity in growing lambs

Journal of the Science of Food and Agriculture, Volume 106, Issue 6, Page 3857-3865, April 2026.
Abstract BACKGROUND Direct fed microbials (DFM) are natural and safe enteric methane mitigants for ruminant livestock systems. While previous studies have demonstrated the effect of Lactobacillus spp. on methane mitigation, challenges remain in effectively delivering DFM in extensive grazing systems. The objective of this experiment was to evaluate the

Productive performance of Holstein calves finished in feedlot or pasture

Anais da Academia Brasileira de Ciências
The use of animals from dairy farms is an alternative to meat production since it provides an increment of total income for farmers. This study aims to evaluate the performance of Holstein calves finished in two feeding systems (feedlot or pasture ...

Elevated quinolizidine alkaloid content in grains of sweet narrow‐leaved lupins when intercropped with oats

Journal of the Science of Food and Agriculture, Volume 106, Issue 5, Page 2917-2927, 30 March 2026.
Abstract BACKGROUND Narrow‐leaved lupins (NLL, Lupinus angustifolius L.) is recognized as a climate‐resilient protein crop but its use in food and feed is frequently limited by toxic quinolizidine alkaloids (QAs). The effect of intercropping with spring oat (Avena sativa L.) on grain QA content has not yet been quantified.

Strategic Advocacy for Higher Education Research: Insights From US Agricultural Experiment Station Funding

Applied Economic Perspectives and Policy, Volume 48, Issue 1, Page 251-265, March 2026.
ABSTRACT Amidst dwindling state funding and the legislative withdrawal from public university research support, a heightened political process shapes the allocation of scarce tax dollars. This article explores how advocacy within the political process influences funding support for higher education from state legislatures.

Performance and carcass characteristics of lambs fed a solution of cheese whey during feedlot and pre-slaughter lairage

Revista Brasileira de Zootecnia, 2018
The objective of this study was to evaluate performance and carcass and meat characteristics of lambs fed a solution of cheese whey plus water (100 g kg−1 dry matter) (CW) during feedlot and pre-slaughter lairage. Data were analyzed as a 2 × 2 factorial (
