Variações diurnas da temperatura corporal, proteínas plasmáticas e eritrograma de cabras não prenhes

Hemogram values may have variations caused by intrinsic or extrinsic factors, which can take healthy animals to present values outside of the normal reference ranges and it is important to the veterinarian to know these variation factors for a correct results interpretation. The influence of the period of the day is among them. The objective of this study was to test the hypothesis that there are hematological parameters variations, such as erythrogram and plasmatic proteins during the day. The study was carried out with 10 non-pregnant adult goats in Araçatuba/SP/Brazil. The blood sampling and physical exam occurred at three moments between 07:00 and 08:00 a.m. (M1), 12:30 and 01:30 p.m. (M2), 5:00 and 6:00 p.m. (M3). We noted differences in the values of packed cell volume (PCV), hemoglobin, and rectal temperature through the moments, with reduction of PCV and hemoglobin were related to increase in rectal and air temperature, leading to water intake increase and, consequently, decreasing blood concentration. These variations could lead to an error of interpretation of the results due to values below the reference ranges.

Proteinograma sérico de bezerros recém-nascidos alimentados com colostro de vacas com mastite

The aim of this study was to evaluate the serum protein concentration in newborns fed with colostrum derived from healthy cows (n = 10), cows with subclinical mastitis (n = 10) and cows with clinical mastitis (n = 10). 30 Holstein cows were assigned to their respective groups according to macroscopic examination of colostral secretion, somatic cell count, CMT and presence of bacteria in colostrum samples. Blood samples of the calves were collected immediately after birth, at 24 and 48 hours after ingestion of colostrum. The total protein was measured by the biuret method and the concentrations of immunoglobulin A (IgA), immunoglobulin G (IgG), transferrin, albumin and haptoglobin was determined by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). No differences were obser- ved amongst groups in the concentrations of albumin, total protein and IgA. In animals from cows with subclinical and clinical mastitis haptoglobin concentrations were higher than those of healthy animals. The concentrations of IgG and transferrin were significantly lower in calves from cows with mastitis. We concluded that the ingestion of colostrum from infected and uninfected glands from cows with mastitis (GII e GIII) is unlikely to be an important contributor to the high rate of failure of passive transfer of immunoglobulins in calves.

Fisiologia da termorregulação e estresse térmico em ovinos lanados

The introduction of wool sheep in warm temperature regions of Brazil has also raised concerns regarding the warm stress and its consequent decrease in animal production. The understanding of the physiology of thermal balance in sheep, as well as the consequences of this phenomenon, should be studied in order to improve animal thermal comfort in association with the production and reproduction indices of these animals. The majority of available research findings related to thermal balance in sheep is derived from countries with temperate climates and therefore might be different from those performed in our climate conditions. This essay presents a literature review that intends to discuss this theme.
