2. Mycotoxin risk management for dairy cows by monitoring blood parameters, reproduction status and SCC in milk
RESUMO O objetivo deste estudo era determinar a eficácia do manejo de micotoxinas com aditivo alimentar através do monitoramento de parâmetros bioquímicos do sangue, estado de reprodução e saúde do úbere em vacas. Durante os primeiros 1-12 meses, o desempenho de reprodução foi avaliado. As vacas foram alimentadas apenas com ração total mista (TMR

4. Errata
Abstract Cheese production is one of the most common forms of valorization of dairy production, adding value and preserving milk. Various types of cheese produced from raw and pasteurized milk are known worldwide. In the present work, we are interested in studying the effect of the type of milk (raw and pasteurized) of two species (cow and goat) on the yield

6. Identification of Methicillin-Resistant Staphylococcus aureus in Bulk Tank Milk
Abstract Staphylococcus aureus is the leading cause of intoxications in humans. Also, methicillin-resistant S. aureus (MRSA) is an emerging problem in food-producing animals. The presence of MRSA in milk may create a risk to public health. The aim of this study was to evaluate the presence of MRSA in bulk tank milk samples. One hundred and twenty bulk tank m

8. Diferentes momentos de aplicação de gonadotrofina coriônica equina em protocolo de inseminação artificial em tempo fixo para vacas de leite
RESUMO Avaliaram-se diferentes momentos de aplicação da gonadotrofina coriônica equina (eCG) em protocolos de inseminação artificial em tempo fixo (IATF) para vacas de leite. Foram utilizadas 76 fêmeas, as quais receberam, no dia zero (D0) do protocolo, dispositivos intravaginais de progesterona, sendo esses retirados no D9, e os animais foram, então,

9. Pre-TAI protocol strategies to increase reproductive efficiency in beef and dairy cows
Abstract Ovulation synchronization protocols are well established in beef and dairy cows. However, the protocol response rate is around 70-90%. In beef cows, factors such as inadequate nutrition and calf presence negatively impact the response of progesterone (P4)/estradiol-based ovulation synchronization protocols by interfering with GnRH release and conseq

10. Inflammation: friend or foe of bovine reproduction?
Abstract Inflammation is not only the first line of defense of the organism but is also required in many reproductive processes such as ovulation, corpus luteum development, luteolysis, uterine clearance after insemination and post partum. Nevertheless, if excessive or persistent, inflammation can switch from a positive mechanism to a deleterious process, im

11. “It’s no longer the same job”: robotization among breeders and dairy cows
Resumo Na agricultura, mecanização e robotização são dois termos geralmente associados a processos usados para caracterizar a “revolução verde”; industrialização, redução dos custos e “racionalização”, aumento da produção e modernização. Neste artigo, proponho uma reflexão, a partir de uma etnografia realizada junto a criadores de v
