Innate immune response in neonate Holstein heifer calves fed fresh or frozen colostrum

Abstract: The aim of this research was to evaluate the influence of maternal cells from colostrum on the development and function of the innate immune response in Holstein calves. Calves were divided into 2 groups: COL+ (n=10) received fresh colostrum; and COL- (n=10) which received frozen colostrum containing no viable cells. The calves were assessed before colostrum intake (D0), 48h of age (D2), and weekly from D7 up to D28. Blood samples were collected for analysis of the distribution of leukocytes, cellular phenotyp… Show more

“…This cytokine induces neutrophil recruitment and activation (Roark et al 2008, Garraud et al 2012). The enhanced IL-17 production reported here could be responsible for the rapid recruitment of neutrophils to mediate bacterial clearance observed in the COL-group, reported by Costa et al (2017).…”

“…The neonate calves have a great ability to absorb immunoglobulins M. Lefkaditis, et al Preventive Veterinary Medicine 176 (2020) 104904 and growth factors from the gut (e.g. IgA, IgM, IgG, IGF-1, lactoferrin, and lysozyme) (Costa et al, 2017). Quality of colostrums is always a crucial factor which ensures that there is sufficient amount of antibodies for absorption by the calves.…”

“…Diversos autores têm pesquisado a respeito do comportamento de fagocitose e metabolismo oxidativo de granulócitos de bovinos jovens e adultos em ensaios ex vivo, visando compreender tal comportamento diante de diferentes variáveis (KAMPEN et al, 2006;AZEDO, 2007;BATISTA, 2011;GOMES, 2016;COSTA et al, 2017). Os linfócitos T CD4 + , chamados auxiliares, atuam reconhecendo antígenos processados (STEVENS & LOWE, 2001;SUETAKE et al, 2006) e possuem receptor para moléculas de MCH tipo II, presentes nas superfícies de células apresentadoras de antígenos.…”

“…presença de produção de EROs sem estímulo verificada no ensaio ex vivo tem sido descrita por diversos autores(AZEDO, 2007;BATISTA et al 2015;COSTA et al, 2017). Tal fato pode ser fundamentado no estímulo natural que ocorre constantemente in vivo; particularmente no período estudado (neonatal), onde o bezerro tem seu sistema imune sendo desafiado a todo o momento pela presença de microrganismos do ambiente.…”
