“…The high number of neutrophils at D7 might be explained by the release of maternal and fetal cortisol in late pregnancy and delivery, or the maturation and release of bone marrow stores of neutrophils following signals from tissues interacting with microbes. This pattern with age has previously been published by Mohri et al (2007), Brun-Hansen et al (2006) and Novo et al (2015).…”

The objective of this research was to evaluate the influence of cells from colostrum on the health of neonate calves. Animals were distributed in 2 groups: COL+ (n=9) which received fresh colostrum from their own damns; and COL- (n=10) which received frozen colostrums from donors. Heifers were assessed before colostrum intake - D0; D2; D7; D14; D21 and D28. Heifers were monitored by clinical examination, hematological profile and serum iron. COL- had a higher diarrhea intensity score (typically 3) on D7. Moreover, a single case each of bronchopneumonia and navel inflammation were observed in COL- calves. COL- had fewer red blood cells (RBC) (6.5±0.8×10/μL) and less hemoglobin (Hgb) (8.3±1.4g/dL) than COL+ (RBC=7.2±0.8×10/μL; Hgb=9.6±1.3g/dL) at D14 (P≤0.05). COL- had more anemia on D21 (P=0.03) and on D28 (P=0.02). Iron was lower in COL- (5.6±2.7μM/L) than COL+ (10.7±6.2μM/L) (P=0.03) on D7. Lymphocytes was lower in COL- than COL+ on D7 (3.8±1.0×10/μL COL+ and 5.4±2.2×10/μL COL-, P=0.02). COL- calves had more anemia and lower serum iron concomitant with diarrhea on D7. The number of leukocytes was relatively consistent in the COL+ calves, while COL- calves showed an increasing number of of lymphocytes starting on D7.

“…Indeed, high levels of cortisol were found in calves soon after birth (KNOWLES et al, 2000;PAIVA et al, 2006). It is important to note that the increase observed in leukocyte counts from lambs and calves was due to the number of neutrophils, supporting the hypothesis that stress is involved (NOVO et al, 2015).…”

“…This may be due to stress at the time of delivery and/or the passage of maternal cells into the neonate's circulatory system during birth. Novo et al (2015) confirmed that the increase in the number of leukocytes in the first hours of life was due to the effects of cortisol. The period after birth is very challenging for lambs because adaptations occur in both the respiratory and circulatory systems.…”

Article history The first months in the life of mammals are marked by many challenges, such as acquisition of maternal antibodies, immunological maturity, environmental exposure and food adaptation. These challenges may lead to changes in the concentration of inflammatory markers, as the acute phase proteins (APPs) and leukocytes. The better understanding of these markers behavior in physiological conditions is fundamental for diagnosis, monitoring, and prognosis of diseases. Therefore, the aim of this study was to determine the changes in the APPs and leukogram profile in Dorper lambs from birth until the sixth month of life. Samples were collected from 12 clinically healthy lambs at 0, 6, 12, 24, 48 hours and then at 7, 15, 30, 60, 90, 120, 150 and 180 days of age. All lambs were born with a low concentration of haptoglobin and ceruloplasmin. Significant increases occurred in the 48 th hour and on the 7 th day of life (P<0.05), respectively. The highest APPs concentration was observed on the 90 th day. All leukogram cells varied throughout the experimental period. It was possible to characterize the changes in APPs and leukogram profile from birth to six months of life in Dorper lambs. This study offers new perspectives on the use of APPs in lambs during the first months of life.

“…Durante o período neonatal a tendência ao aumento dos valores de eritrócitos, Hb e VG, observada no presente trabalho, para a raça Aberdeen Angus (Red Angus) e Crioula Lageana variedade mocha (exceto para a variável Hb) [Tabela 1], assemelha-se com observações realizadas em bezerros da raça Holandesa [19]. Entretanto, bezerros holandeses apresentaram diminuição nos valores destas variáveis a partir do nascimento (> 6 h) até o terceiro e quarto dia para o número de eritrócitos e Hb, e até o quinto e sexto dia para o VG.…”

“…As flutuações com tendência a diminuição de seus valores para a variável VCM no período neonatal, em ambas as raças (Tabela 1), corroboram com observações realizadas por outros autores em bezerros da raça Holandesa [3,19]. Tendência a diminuição dos valores de HCM no período neonatal também foi observado em bezerros da raça Holandesa [19], semelhante ao encontrado no presente trabalho para a raça Aberdeen Angus (Red Angus). No entanto, para a raça Crioula Lageana variedade mocha os valores desta variável apresentaram diminuição seguido por aumento neste período.…”

Background: Neonatal period in bovine presents important variations in hematologic and immunologic parameters, and the resulting mortality rates may be due to increased susceptibility to disease. Race, age, environmental, climate and management factors are sources of CBC's parameters variation in cattle. The objective of this study is to evaluate and compare the CBC variables and concentrations of total protein (PTP) and plasma fibrinogen calves of Criolo Lageano Breed variety hornless and Aberdeen Angus (Red Angus) in the first six months of life, which are produced under extensive management at the Planalto Serrano Catarinense (southern Brazil). Materials, Methods & Results:Two groups were selected, comprising 11 calves of Hornless Criolo Lageano and 14 calves of the Aberdeen Angus breed (Red Angus). Blood samples were collected for complete blood count and determination of total protein concentrations, and plasma fibrinogen in the periods between 24 h and 36, 15, 30, 60, 90, 120, 150 and 180 days of life. The statistical analysis was performed using analysis of variance for repeated measures (ANOVA) and Tukey's test (P < 0.05). During the experimental period infestations by ticks in both races were observed. In the first month of life, blood smears revealed the presence of blood parasites of the genus Babesia spp. and Anaplasma sp. The fluctuations seen for erythrocyte in the neonatal period (30 days), although not significant, consisted of raising the number of values of erythrocytes, hemoglobin (Hb) and packed cell volume (PCV), and reduction in mean corpuscular volume values (MCV). From 90 days of age there was a significant reduction in number of red blood cells and VG values, and elevated MCV values and mean corpuscular volume (MCHC) for the Aberdeen Angus (Red Angus). For the WBC, the neonatal period was marked by increase in the number of lymphocytes and decrease in neutrophil ratio: lymphocyte (N, L) with respect to the inversion of 15 days. In the age group 90 days of life was evident increase in the number of leukocytes and lymphocytes in both races. The plasma fibrinogen concentrations showed no significant variations during the trial period. The plasma total protein (PTP), had higher values on the second day of life, with reductions up to 60 days and gradual increase in subsequent times. Discussion: The fluctuations related to the values of erythrocyte variables in the neonatal period are consistent with results reported by other authors in calves of other races. Changes in erythrocyte values observed from 90 days of age on race Aberdeen Angus (Red Angus) can be attributed to infection by blood parasites and consequent hemolysis. As for the leucocyte count, increasing the number of lymphocytes and inversion of N:L is the neonatal period in a physiological variation and confirms observations made by other authors in calves of other races. In the age group 90 days, leukocytosis by lymphocytosis was related to natural premonition against Babesia spp. and Anaplasma spp., which is documented in cattle i...
