The aim of this study was to evaluate secondary clinical disease, milk production efficiency and reproductive performance heifers cows persistently infected (PI) with bovine viral diarrhea virus type 2 (BVDV 2). PI animals (n = 25) were identified using an antigen capture ELISA ear notch samples. They distributed into three age groups: ≤ 12 8), 13 24 6) 25 34 11) months old. A control group BVDV negative female cattle that matched the utilized from same herd. had a 1.29 higher odds ratio for...
Background: Infections are caused by Bovine Viral Diarrhea Virus and still continue to be a worldwide plague in cattle industry. It is responsible for sudden death syndromes adult with high mortality rates, abortions, acute gastrointestinal respiratory diseases. The BVDV infection occurs early pregnancy (40-142 days), immunosuppressed females or cows results 100% of persistently infected (PI) calves that seronegative asymptomatic at birth. Evidences suggests contributes BRD complex...
ABSTRACT: The early use of antimicrobial therapy has been introduced in many farms to prevent diarrhea and respiratory disease young calves; however, there is controversy about whether this practice a beneficial effect on the health these animals. This study evaluated influence antimicrobials performance neonatal Holstein calves. Twenty-six calves were screened divided into two groups, according administration (ATB+), or not (ATB-) tulathromycin (2.5mg/kg, subcutaneously) within first 12...
O objetivo desta revisão é trazer informações atualizadas sobre o papel dos fatores imunes do colostro, além das imunoglobulinas (Igs), na proteção direta ou indireta bezerros. Os recém-nascidos são hipogamaglobulinêmicos e imunossuprimidos, de possuírem sistema imune adaptativo näive. Desta forma, consensual que a colostragem prioridade no criação bezerras, entretanto as novas descobertas atuação leucócitos maternos seus subprodutos (citocinas), amplificando os mecanismos da resposta inata...
ABSTRACT: We evaluated some indicators of innate and humoral immune response in persistently infected (PI) Holstein calves cows from 1 to 36 months age matched with controls the same herd. The effects were cataloged by grouping animals into following groups: <12 months, 13 24 25 age. Blood samples collected once each animal measure total serum protein, haptoglobin, neutralizing antibodies titers induced respiratory virus vaccination. Total protein (g/dL) was lowest PI younger until old,...
