Bovine subclinical mastitis (SCM) is the costliest disease for dairy industry. Technologies aimed at early diagnosis of this condition, such as infrared thermography (IRT), can be used to generate large amounts data that provide valuable information when analyzed using learning techniques. The objective study was evaluate and optimize use machine by applying Extreme Gradient Boosting (XGBoost) algorithm in bovine SCM, based on udder thermogram analysis. Over 14 months, a total 1035 milk...
Haemonchus contortus, a gastrointestinal nematode parasite of sheep, is mainly controlled by anthelmintics; the occurrence anthelmintic resistance leads to treatment failures and increases economic burden. Because molecular mechanisms involved in drug can be elucidated genomic studies, an extreme quantitative trait locus (X-QTL) mapping approach was used identify co-segregation phenotype with genetic markers detect genome-wide variants associated monepantel H. contortus.A cross between...
Resumo: A inflamação da glândula mamária é uma das principais causas de prejuízo na ovinocultura. Este estudo teve como objetivo investigar as taxas cura do tratamento mastite subclínica após infusão intramamária princípio ativo antimicrobiano no momento secagem, em formulações convencional e nanoparticulada. Os rebanhos estavam localizados São Carlos, Paulo, Brasil. Analisou-se um total 584 glândulas mamárias 307 ovelhas aptidão para produção carne. Triagem prévia dos casos subclínicos foi...
ABSTRACT: Coagulase-negative Staphylococcus spp. (CNS) are the main microorganisms involved in ovine mastitis. Treatment at end of lactation can contribute towards cure and prevention subclinical cases during subsequent lactation. However, virulence factors resistance mechanisms presented by CNS decrease rates. The aims study were to identify species milk mastitic ewes with without antimicrobial treatment, investigate presence genes relating β-lactam antimicrobials, formation biofilms,...
The aims of this study were to determine the occurrence subclinical mastitis in sheep different breeds and values for somatic cell count (SCC) milk diagnosis disease at lactation weaning, a fundamental prerequisite identifying animals need control measures. Milk samples obtained from 1,457 mammary halves Santa Inês, Texel, Ile de France, Dorper two periods, during second week weaning. After teats antisepsis, collected, identification infectious etiology determination SCC performed....
ABSTRACT: Mastitis negatively influences the survival and weight gain of ovines for meat production. The purpose this study was to investigate, in sheep production, occurrence subclinical mastitis ewes at end lactation beginning consecutive assess composition cellular characteristics milk as a function different rainfall indices. Mammary halves (821) Santa Ines (479) Morada Nova (342) were examined. Milk samples collected two moments lactation: weaning postpartum lactation. Sample collection...
O objetivo desse estudo foi avaliar a ocorrência da mastite subclínica ovina em duas lactações e evolução doença consecutivas. As amostras de leite foram originadas um rebanho com 160 ovelhas raça Santa Inês. Na primeira lactação, colheram-se aos 14 dias pós-parto no período próximo ao desmame. segunda as colhidas dos mesmos animais pós-parto, 52 A triagem casos feita preliminarmente por meio do California Mastitis Test (CMT). para investigação microbiológica obtidas metades mamárias...
II SIMPÓSIO DE QUALIDADE LEITE O Simpósio de Qualidade Leite aconteceu nos dias 05, 06 e 07 setembro 2014, no Centro Convenções da Faculdade Ciências Agrárias Veterinárias, Unesp, Câmpus Jaboticabal, SP. Foi um evento organizado por pós-graduandos do Departamento Medicina Veterinária Preventiva, sob a supervisão Prof. Dr . Antonio Nader Filho (homenageado V Congresso Brasileiro Leite, 2013, pelos importantes trabalhos desenvolvidos na área). Tendo em vista o sucesso obtido edição anterior,...
