With the growing use of crossbred cattle in Brazilian feedlots and increasing pressure to reduce antibiotic as growth promoters, this study examines impact three feed additives—monensin (MON), monensin with Lithothamnium calcareum (LCM), a blend essential oils (BEO)—on performance Nellore (NEL) (CROSS) cattle. A total 90 bulls were assigned completely randomized block design 2 × 3 factorial for 112 days, all received same diet varying additives. Their methane (CH4) emissions estimated. All...
Two experiments were conducted to assess the effects of water medication technology on beef cattle behaviour and performance in tropical conditions. Experiment 1 involved 30 Droughtmaster yearling steers monitored over seven days a controlled environment. Feed consumptions with Smart Pro® systems, three treatments administered via uDOSE® technology. The results indicated an average intake 13.6 L/head/d. 2 had 120 from four genetic groups grazing extensive pasture system. Throughout 24-day...
Abstract Two experiments were conducted to determine the potential for essential oil blend Agolin Ruminant L (Agolin) reduce enteric methane (CH4) emissions from beef cattle when delivered via drinking water. Experiment 1 evaluated aqueous solutions of (50 mg/L) and a nonprotein nitrogen mineral solution (uPRO ORANGE [uPRO]; 1.7 mL/L) individually in combination, where was added concentrated uPRO at 3%, 4.5%, 6% (w/w) prior dilution with water mL/L, total 5 treatments. These incubated 48 h...
Water-based nutrient injection technology, widely used in sectors like viticulture, hydroponics, and intensive animal systems, has previously seen limited application livestock production. Early mechanical dispensers for nutrients, such as non-protein nitrogen (NPN) phosphorus (P), were prone to malfunction, leading inconsistent dosing potential health risks. This contributed skepticism slow adoption among producers. However, recent technological advancements have renewed interest...

Knowledge of animal behavior can be indicative the well-being, health, productivity, and reproduction animals. The use accelerometers to classify predict a tool for continuous monitoring. Therefore, aim this study was provide strategies predicting more less frequent beef cattle grazing behaviors. activities observed were grazing, ruminating, idle, water consumption frequency (WCF), feeding (supplementation) walking. Three Machine Learning algorithms: Random Forest (RF), Support Vector (SVM)...
Heifer early calving (HC) plays a key role in beef cattle herds' economic sustainability and profitability by reducing production costs generation intervals. However, the genetic basis of HC Nelore heifers at different ages remains to be well understood. In this study, we aimed perform multi-trait weighted single-step genome-wide association (MT w-ssGWAS) uncover mechanism involved 24 (HC24), 26 (HC26), 28 (HC28), 30 (HC30) months age heifers. The MT w-ssGWAS pointed out four shared windows...
The identification of genomic regions associated with reproductive traits as well their biological processes allows a better understanding the phenotypic variability these traits. This information could be applied to animal breeding programs accelerate genetic gain. aim this study was evaluate association between single nucleotide polymorphisms (SNP) scrotal circumference at 365 days age (SC365) and 450 (SC450), gestation length (GL) calf trait, first calving (AFC), accumulated productivity...
This study aimed to evaluate population parameters and describe the genetic diversity of Quarter Horse breed (QH) in Brazil, reported for first time literature. The pedigree data comprised 131,716 animals representing total (TP), with records born between 1747 2008. reference (RP) last generation was applied this considering 47,861 2000 average interval 9.6 10.8 years TP RP, respectively. equivalent complete generations (EG) were 5.09 (TP) 6.24 (RP). inbreeding coefficient (F), relatedness...
The Tabapuã breed is a beef cattle Brazilian known for its sexual precocity and desirable characteristics tropical conditions. However, this newly formed few studies have been conducted regarding genetic parameters trends reproductive traits. objective of the present study was to estimate parameters, trends, relative selection efficiency weaning weight adjusted 210 d age (W210), at first calving (AFC), average interval (ACI), (CI1), accumulated productivity (ACP) among cattle. Pedigree data...
The aim of this study was to evaluate the level introgression breeds in Canchim (CA: 62.5% Charolais-37.5% Zebu) and MA genetic group (MA: 65.6% Charolais-34.4% cattle using genomic information on Charolais (CH), Nelore (NE), Indubrasil (IB) breeds. number animals used 395 (CA MA), 763 338 37 (IB). Bovine50SNP BeadChip from Illumina panel estimate levels considering Maximum likelihood, Bayesian, Single Regression method. After genotype quality control, 32,308 SNPs were considered analysis....
Animal behavior monitoring is an important tool for animal production. This strategy can indicate the well-being and health of animals, which lead to better productive performance. study aimed assess most effective accelerometer attachment position (on either halter or a neck collar) data transmission time intervals (ranging from 6 600 s) predicting behavioral patterns, including water food intake frequencies, as well other activities in young beef cattle bulls within feedlot system. A range...
Understanding economic scenarios is crucial in all production chains. Tropical pastures are Brazil’s primary food source for beef cattle production, and current pasture management not ideal due to land degradation. An evaluation assists farmers with improving using novel techniques, such as nitrogen (N) fertilization, which straightforward practical. The effects of different N fertilizer levels were evaluated. This study was conducted over three years (2014/2015, 2015/2016, 2016/2017) four...
Abstract This study compared imputation from lower-density commercial and customized panels to high-density a combined panel (Illumina Affymetrix) in Nelore beef cattle. Additionally, linkage disequilibrium haplotype block conformation were estimated individual with corresponding values the after imputation. Overall, 814 animals genotyped using BovineHD BeadChip (IllumHD), 93 of these also Axion Genome-Wide BOS 1 Array Plate (AffyHD). In general, customization considering minor allele...
