Gestation and puerperium influence over ter blood proteinogram of bovines of the black and white Dutch breed

Abstract

The variances in the serum proteic picture of bovines in gestation were studied in 75 black and white Dutch breed heifers. At the end of the gestation period there was noticed a significant increase in the contents of albumin and albumin/globulin relationship and a significantly statistical decrease in the values of total protein, globulins and gamma-globulin. The plasmatic fibrinogen presented an evidently higher value in the recent puerperium (up to 3 months after parturition). The results obtained for the group of empty heifers, animals in their initial gestation phase, between 4 and 6 months of gestation, heifers at the end of their gestation, and for cows during their puerperium period were respectively as follow: Total protein: 6.16g%; 6.51g%; 6.20g%; 5.72g%; and 5.87g%. Albumin: 1.75g%; 1.65g%; 1.69g%; 2.25g% and 1.85g%. Globulins: 4.40g%; 4.86g%; 4.54g%; 3.47g% and 4.01g%. Gamma-globulin: 2.32g%; 2.54g%; 2.29g%; 1.99g% and 2.29g%. Albumin/globulin relationship: 0.41; 0,35; 0,38; 0.64 and 0.49. Fibrinogen: 622.5mg% 741.6mg%; 665.9mg%; 625.7mg% and 762.3mg%.
