“…for overall adaptation of neonatal calves to the new environmental factors after birth related to the drastic change from primarily parenteral nutrition during the fetal period to exlusively enteral provision of nutrients at birth (Blum and Hammon, 2000;Blum and Baumrucker, 2002;Levieux, 1999). However, in neonatal calves "gut closure" with respect to protein macromolecules such as globulins occurs in neonatal period Georgiev, 2005), this could explain the decrease of á-globulins that we observed during the first month of life.…”

The authors studied the course of serum proteins during the first week and the first month of life in the calf in order to obtain useful information for neonatal care. Eight Limousine calves, four males and four females, clinically healthy, were used. From all animals blood samples were collected from the external jugular vein from the day after the birth every day for one week and every five days for thirty days. Blood samples were taken at the same hour (09:00), and the serum concentrations of albumin, globulins (α1-globulins, α2-globulins, β- globulins, γ-globulins) and total proteins were determined by means of automated multiparametric agarose gel electrophoresis system. One-way repeated measures analysis of variance (ANOVA), followed by the Bonferroni's test, was used to determine significant differences. Data analysis of variance showed a significant effect of days of life, with p < 0.05, only on albumin, α1-globulins and α2-globulins during the first month of life. These results confirm that despite the fact that newborns must adapt to various environmental factors after birth, including nutrition that can influence the serum protein profile during neonatal period, the evaluation of electrophoretic's parameters during the first months of life results useful for the diagnosis and treatment of neonatal diseases

“…In our study, the contents of lysozyme, peroxidase, IgA, and IgM were higher in commercial milk than those in colostrum. It could be explained by Levieux ( 29 ), who revealed that trace elements decrease abruptly during the first milking postpartum and then increase in late lactation that may be due to the udder involution before calving. In addition, it also has been confirmed that lactoperoxidase content in bovine colostrum is low and reaches its maximum concentration between 3 and 5 days postpartum ( 30 ).…”

The Blood Immune Cell Count, Immunoglobulin, Inflammatory Factor, and Milk Trace Element in Transition Cows and Calves Were Altered by Increasing the Dietary n-3 or n-6 Polyunsaturated Fatty Acid Levels

Transition dairy cows experience sudden changes in both metabolic and immune functions, which lead to many diseases in postpartum cows. Therefore, it is crucial to monitor and guarantee the nutritional and healthy status of transition cows. The objective of this study was to determine the effect of diet enriched in n-3 or n-6 polyunsaturated fatty acid (PUFA) on colostrum composition and blood immune index of multiparous Holstein cows and neonatal calves during the transition period. Forty-five multiparous Holstein dairy cows at 240 days of pregnancy were randomly assigned to receive 1 of 3 isoenergetic and isoprotein diets: 1) CON, hydrogenated fatty acid (control), 1% of hydrogenated fatty acid [diet dry matter (DM) basis] during prepartum and postpartum, respectively; 2) HN3, 3.5% of extruding flaxseed (diet DM basis, n-3 PUFA source); 3) HN6, 8% of extruding soybeans (diet DM basis, C18:2n-6 PUFA source). Diets containing n-3 and n-6 PUFA sources decreased colostrum immunoglobulin G (IgG) concentration but did not significantly change the colostrum IgG yield compared with those with CON. The commercial milk yield (from 14 to 28 days after calving) was higher in the HN3 and HN6 than that in the CON. Furthermore, the n-3 PUFA source increased neutrophil cell counts in blood during the prepartum period and increased neutrophil percentage during the postpartum period when compared with those with control treatment. Diets containing supplemental n-3 PUFA decreased the serum concentration of interleukin (IL)-1β in maternal cows compared with those in control and n-6 PUFA during prepartum and postpartum. In addition, the neonatal calf serum concentration of tumor necrosis factor (TNF) was decreased in HN3 compared with that in the HN6 treatment. The diet with the n-3 PUFA source could potentially increase the capacity of neutrophils to defend against pathogens in maternal cows by increasing the neutrophil numbers and percentage during the transition period. Meanwhile, the diet with n-3 PUFA source could decrease the pro-inflammatary cytokine IL-1β of maternal cows during the transition period and decline the content of pro-inflammatary cytokine TNF of neonatal calves. It suggested that the highest milk production in n-3 PUFA treatment may partially be due to these beneficial alterations.

“…The composition of ruminant colostrum is quite different from that of milk in established lactation. Proteins secreted by the mammary gland such as βlactoglobulin (β-lg), α-lactalbumin (α-la) and lactoferrin, or proteinase inhibitors and proteins derived from blood such as albumin, α # -macroglobulin and transferrin are present in higher concentrations in colostrum (reviewed by Levieux, 1999). However, colostrum is mostly characterized by its very high level of immunoglobulin G (IgG), essentially from the IgG " subclass which is actively concentrated from the serum to the mammary gland during the last weeks prior to parturition (Pahud & Mach, 1970 ;Micusan & Borduas, 1976 ;Butler, 1981).…”

Colostrum and milk samples from 20 goats were analysed for concentrations of immunoglobulin G (IgG), β-lactoglobulin (β-lg), α-lactalbumin (α-la) and serum albumin (CSA) throughout the first 14 milkings post partum (7 d of lactation) using single radial immunodiffusion assay. Concentrations (mg/ml, means±SD) at first milking were IgG 47·9±25·5, β-lg 30·7±10·4, α-la 2·77±0·82 and CSA 2·97±2·46 mg/ml. Large variations were recorded for IgG concentrations (19·9–94·5 mg/ml) and β-lg (9·3–49·8 mg/ml). Concentrations of IgG, β-lg and CSA dropped abruptly in the subsequent milkings and α-la concentration decreased slowly. Mean IgG concentration was <2 mg/ml after 7 milkings and <1 mg/ml after 11 milkings. However, IgG concentration does not differ significantly, at the 1% level, from milkings 7–14. The contribution of β-lg to the increase in whey proteins in early milks was greater than that of IgG from milkings 5 to 14. The results were tabulated to make it possible to calculate the excess of whey proteins that would be obtained if early milks were illegally added to milk supply.
