“…At birth the concentration of serum proteins in most animals is quite low, due to minimal quantities of immunoglobulins and lower concentrations of albumin (Kaneko 1997). After colostrum intake total protein concentration rapidly increases (Loste et al 2008) and the intensity of changes is dependent on colostrum composition (Hashemi et al 2008). In our study the highest mean concentrations of TP were observed 24 h after birth in calves and lambs.…”

The objective of this study was to evaluate the influence of colostrum intake on the serum protein electrophoretic pattern in clinically healthy calves, lambs and kids during the first two weeks of life, as well as differences in the protein profile between these species of ruminants. The study included three groups of clinically healthy calves (n = 12), lambs (n = 10) and kids (n = 7). The first blood sampling was performed before the colostrum intake (day 0) and then at 1, 2, 7 and 14 days of age. Blood serum was analysed for the concentrations of total proteins, serum protein electrophoretic fractions and albumin/globulin ratio. Serum protein electrophoresis identified in calves 6 (albumin, α 1 -, α 2 -, β 1 -, β 2 -, and γ-globulins) and in lambs and kids 5 (albumin, α 1 -, α 2 -, βand γ-globulins) distinct bands. Significant changes were observed in the analysed parameters during the evaluated period in all groups of ruminants. Except of the concentration of total proteins in precolostral serum significant differences in the results were found also between ruminant species. The present study showed significant effect of colostrum intake on concentrations of total proteins and also relative and absolute concentrations of the major of protein fractions in all evaluated species of young ruminants. The results, analysis of which began already in precolostral time, indicate that colostrum feeding is the starting point for significant changes in protein profile in ruminant neonates followed by longer-lasting changes in the following days and weeks of their life.

“…De fato, a concentração de IgG não foi diferente entre machos e fêmeas, o que está de acordo com outras observações (Ciupercescu 1977, Hunter et al 1977, Sawyer et al 1977, Gilbert et al 1988, Bekele et al 1992, Ahmad et al 2000, Kahn et al 2006, Nunes 2006 (Mellor & Murray 1985, 1986. Porém a sua concentração de IgG não se reduz (Al-Sabbagh et al 1995, Nunes 2006, Hashemi et al 2008, Swanson et al 2008. O menor volume de colostro pode ser suficiente para permitir a TIP bem sucedida no cordeiro único, entretanto, aumenta o risco de FTIP no caso dos gêmeos.…”

“…Esses estudos apontaram que o sucesso da TIP pode ser comprometido no caso das ovelhas primíparas e das mais velhas (Halliday 1976, Gilbert et al 1988, dos partos gemelares (Halliday 1976, Hunter et al 1977, McGuire et al 1983, Christley et al 2003, da restrição alimentar das ovelhas durante a gestação (Halliday 1978, Mellor & Murray 1985, 1986) e do nascimento de cordeiros prematuros (Hough et al 1990) e de cordeiros com peso reduzido (Ahmad et al 2000, Christley et al 2003, Kahn et al 2006. Contudo, as contradições entre os resultados não são incomuns (AlSabbagh et al 1995, Hashemi et al 2008, Swanson et al 2008). …”

Aspects related to passive transfer of immunity (PTI) were studied in 290 newborn lambs, crosses of Texel, kept with their mothers on extensive management intropical weather. Blood samples were taken between 24 and 36 hours of life. Serum gamma glutamyltransferase activity, total protein concentration, measured by refractometry and colorimetry, albumin, alfa, beta and gammaglobulins concentrations, measured by agarose gel electrophoresis, and IgG concentration estimated by the zinc sulphate turbidity test were determined. The lambs were grouped according to sex, ewe number of parturitions and body condition scoring, number of lambs born, birth weight and vitality. The risk factors for failure of passive transfer of immunity (FPT) were identified and the association with lamb mortality was tested. Correlations between variables were established. There was no effect of sex, number of parturitions of ewes and ewe body condition scoring on PTI of lambs. However there were differences between singles and twins and between lambs born with good or lightweight (<3 kg). The FPT was infrequent (12.4%), more likely in twins (p=0.026) and in lightweight lambs (p<0.001), and was strongly associated with lamb deaths up to 60 days of age (p<0.001). The global mortality rate was 11.3%; and 30.5% of the lambs with FPT died, almost all in their first month of life. The total protein concentration, measured by refractometry, was correlated (p<0.001) with gammaglobulins (r=0.816) and IgG (r=0.810); and values ≤ 5.0g/dL can be accepted for the diagnosis of FPT. Under tropical weather conditions FTP must be considered infrequent in crossbred meat lambs. However the surveillance and care must be intensified with twins and lambs with low birth weight.

“…Isso ocorre pela alta correlação entre globulinas séricas e globulinas colostrais, especialmente imunoglobulinas G (IgG), inexistindo aumento dos teores séricos proteicos quando são fornecidos leite ou substitutos de colostro para ruminantes neonatos 30,31 . Além disso, estudos demonstram que os teores séricos proteicos relacionam-se diretamente à quantidade e ao tempo de fornecimento de colostro 32 e podem variar em função da qualidade da dieta consumida pelas ovelhas em lactação 33 . Os cordeiros deste estudo apresentaram alternância simultânea entre o predomínio das frações albumina e de globulinas totais, antes e após a ingestão de colostro, constatando-se decréscimo (P<0,05) da concentração de albumina após 72 horas de vida.…”

RESUMOO objetivo deste estudo foi verificar a influência do colostro nos parâmetros bioquímicos séricos em cordeiros recém-nascidos. Foram colhidas amostras sanguíneas de 28 cordeiros, determinando-se os indicadores proteicos, energéticos, de função renal, bilirrubinas e as enzimas aspartato aminotransferase (AST), gamaglutamiltransferase (GGT) e creatina quinase (CK), nos momentos pré e pós-colostro. Os dados foram analisados comparando-se a variabilidade dos parâmetros entre os dois momentos. Houve elevação (P<0,001) das concentrações de proteínas totais, em resposta ao forte aumento (P<0,01) dos teores de globulinas totais e ao leve decréscimo (P<0,05) da concentração de albumina, após a ingestão colostral. Também foram observados maiores valores de bilirrubinas total e direta (P<0,001), e variação dos metabólitos renais, com elevação dos níveis de ureia (P<0,01) concomitante à redução dos valores de creatinina (P<0,001), no momento pós-colostro. Houve aumento (P<0,001) da glicemia, de colesterol total e triglicerídeos, bem como das atividades enzimáticas (P<0,001) de AST e GGT, entre os momentos avaliados. Conclui-se que a dinâmica do perfil bioquímico em cordeiros recém-nascidos sofre o efeito da ingestão de colostro e da adaptação das funções fisiológicas à vida extra-uterina. Os valores dos parâmetros variam marcadamente no período pós-natal, sendo recomendável a utilização de valores de referência próprios para esta fase.

PRE AND POST-COLOSTRAL DYNAMICS OF BIOCHEMICAL PARAMETERS IN LAMBS ABSTRACTThis study aimed to verify the influence of colostrum in serum biochemical parameters in newborn lambs. Blood samples were taken of 28 lambs, determining the protein, energy and kidney function indicators, bilirrubins and the enzymes aspartate aminotransferase (AST), gammaglutamyl transferase (GGT) and creatine kinase (CK), in pre and post-colostrum moments. The data were analyzed comparing the variability of the parameters between the two moments. There was an elevation (P<0.001) in total protein concentrations, in response to substantial increase (P<0.01) in total globulin levels, and a slight decrease (P<0.05) in albumin concentration, after colostral intake. We also observed higher values of total and conjugated bilirubins (P<0.001), and variation of kidney metabolites, with an elevation of urea levels (P<0.01) concomitant to decrease of creatinine values (P<0.001) in the postcolostrum moment. There was an increase (P<0.001) in glycemia, total cholesterol and triglycerides, as well as of
