Factors affecting colostrum quality of ewes and immunostimulation

Occurrence Patterns and Population Density of Barking Deer (Muntiacus Vaginalis) in the Southern Slopes of Himalaya Foothills, Punjab, Pakistan

“…In addition, there is another factor that affects the concentration of colostral IgG, in which is the age of ewes. Adult ewes could produce more colostrum with higher concentration of IgG than younger animals (Yilmaz and Kasikci, 2013), this finding supported our results because ewes in the present study were middleaged animals. Also, another important factor is the ewes' udder condition.…”

“…In the present study, IgG was measured in both serum and colostrum samples, but there are two other classes of Igs that are usually synthesized during the last few weeks of pregnancy by the plasma cells, which are located in the sub-mucosa of the mammary gland epithelium (i.e. IgM, and IgA) (Yilmaz and Kasikci, 2013). In small ruminant's colostrum, IgG accounted for more than 70 to 85% of the total Igs in the body.…”

Case report: failure of passive transfer and neonatal infections in a cohort of lambs

“…Colostrum intake can also be indicated by γ-Glutamyl Transferase (GGT) levels in lamb plasma, as GGT levels are high in colostrum and are readily absorbed by neonatal lambs (Maden et al 2003;Britti et al 2005). Low ZST but adequate GGT results in lambs in this case indicated that either the colostrum quantity, quality or time of intake were inadequate (Yilmaz and Kasikci 2013). Neonatal deaths often increase towards the end of lambing (Casellas et al 2007), although one study has shown an association between early lambing season births and reduced lamb serum immunoglobulin (Christley et al 2003), as was seen in this case.…”

“…Staff were advised to check ewe udders for milk immediately after parturition and check whether lambs had suckled within two hours of birth. The probiotic supplement was not to be given before lambs had colostrum, to reduce the risk of introducing bacteria before acidification of the abomasum or the arrival of colostral antibodies (Yilmaz and Kasikci 2013).…”

Immunoglobulin profile of ovine biological body fluids

“…Концентрация каждого класса иммуноглобулинов в сыворотке крови овец свидетельствует о той роли, которую они играют в защите организма от инфекции. Основным иммуноглобулином сыворотки крови является IgG, обладающий выраженными защитными свойствами, его уровень определяет иммунный статус и степень защиты организма от различных патогенов и неблагоприятных факторов окружающей среды, он -индикатор эффективности передачи иммуноглобулинов через молозиво [3,7,11]. В слюне и носовом секрете доминирующим классом иммуноглобулинов является IgA, на долю которого в этом секрете приходится соответственно 79,9 и 62,6%.…”
