Understanding forage quality is essential for meeting animal demands and optimizing production. This study aimed to: (i) test the applicability of machine learning models with tabular data such as climate variables, light interception (LI), nitrogen dose (N dose), interval between grazing (G...
Animal production in the tropics is done mostly on native and cultivated pastures. Brazil is predominantly tropical and is the fifth largest country in the world with about 20% of its area covered by pastures (174 million ha). It has a natural aptitude for livestock produ...
Pastures of Brachiaria decumbens cv. Basilisk radically changed the scenario of central Brazil livestock production from the early 1970s and allowed the development of this vast region. Despite of the reasonable biomass yield and nutritional value, susceptibility to grassland spittlebugs limits&#...
ABSTRACT - This study assessed the economic feasibility of supplementation leveIs for beef catt1e grazing tropical pastures during the dry season. The central question was whether higher supplementation rates could improve system profitability and what leveI would provide the most advantageous&#x...
RESUMO - Objetivou-se determinar a composição, termogravimetria e calorimetria exploratória diferencial dos farelos de crambe e de soja destinados à alimentação de ruminantes. Foram avaliados o farelo de crambe, proveniente dos grãos cultivar FMS-Brilhante, e o farelo de soja, obtidos após e...
ABSTRACT - This large-scale study evaluated 25,512 Nellore bulls raised under tropical field conditions to elucidate multivariate determinants of breeding soundness and to derive a data-driven risk stratification framework based on BSE outcomes. Macro- and microscopic semen traits (e.g., progressive&#...
ABSTRACT - Background/Objectives: Antimicrobial resistance (AMR) is a global health threat, with raw milk serving as a potential reservoir for antimicrobial resistance genes (ARGs) and mobile genetic elements (MGEs). This study characterized the resistome and mobilome of raw milk from cows&#...
RESUMO - Objetivou-se selecionar variedades de cana-de-açúcar de ciclo médio-tardio para a alimentação animal, sob as condições edafoclimáticas de Mato Grosso, utilizando-se como parâmetros a digestibilidade da matéria orgânica (DIVMO), os nutrientes digestíveis totais (NDT), a quantidade de matéria o...
RESUMO - Objetivou-se avaliar a qualidade nutricional de concentrados protéicos contendo diferentes teores de farelo de crambe em substituição ao farelo de soja, tradicionalmente usado como fonte de proteína básica, na nutrição de ruminantes. Para isso, realizou-se análises para determinação da&#...
RESUMO - Objetivou-se determinar o valor nutricional do farelo de crambe em comparação ao farelo de soja, tradicional fonte de proteína na nutrição de ruminantes. Os farelos de crambe e soja foram obtidos após extração do óleo contido nos grãos em prensa mecânica do tipo ...
