Abstract

The blood glucose and the plasma non-esterified fatty acids (NEFA) and insulin concentrations were estimated in jugular blood samples from 18 Alpine×Beetal and Sannen×Beetal goats during pregnancy and compared with samples from non-pregnant goats and from goats during the periparturient period. The blood glucose levels in the pregnant goats rose to a peak of about 60±1.36 mg/ml at 42–56 days and then declined to about 46±2.37 mg/ml at 112–126 days. In non-pregnant goats, the blood glucose levels were significantly (p<0.01) higher="" than="" in="" pregnant="" goats,="" except="" between="" days="" 42="" and="" 70="" (59±1.36="" mg/ml).="" on="" the="" day="" of="" kidding,="" the="" levels="" declined="" significantly=""><0.01), increasing="" again="" thereafter.="" the="" plasma="" nefa="" concentrations="" were="" significantly="" higher="" in="" pregnant="" than="" in="" non-pregnant="" goats="" from="" days="" 56="" to="" 126.="" the="" nefa="" concentration="" increased="" on="" the="" day="" of="" kidding,="" followed="" by="" a="" transient="" fall="" by="" day="" 3.="" the="" plasma="" insulin="" concentration="" was="" usually="" higher="" in="" pregnant="" than="" in="" non-pregnant="" goats,="" except="" between="" days="" 56="" and="" 70="" and="" from="" day="" 126="" onwards.="" the="" insulin="" concentration="" fell="" late="" in="" pregnancy,="" but="" there="" was="" a="" transient="" increase="" 2="" days="" after="" parturition.="" the="" blood="" glucose="" and="" plasma="" nefa="" concentrations="" can="" be="" used="" as="" indices="" of="" nutritional="" status="" during="" pregnancy="" in="" goats.="">
