A study was carried out to examine the prevalence of pregnancy toxemia due to inadequate feeding of local breeds of goats in India. Three hundred goats of local breeds in pregnancy were selected. They were assessed for feeding management through questionnaire, body condition score and pregnancy for number of fetuses with ultrasonography. The blood samples were collected and assayed for blood glucose level and β-hydroxy butyric acid (BHBA). The Body condition score (BCS) less than 2, blood glucose < 40 mg/dl and BHBA > 0.8 mg/dl were considered positive indicator for pregnancy toxemia. The feeding regime was documented in sub clinical pregnancy toxemia goats and the feed and fodder samples were collected from 10% of these animals. The predominant feeding regime for pregnancy toxemia in the survey was identified and further studied for Dry matter intake (DMI) and nutrient intake. The overall prevalence of pregnancy toxemia was 36.7 %. The incidence of subclinical pregnancy toxemia increased significantly (P < 0.01) in late stage (34.3 %) than in early stage of pregnancy (2.7 %) and was found to be significantly (P < 0.01) higher in animals bearing twins. The average DMI of pregnancy toxemia does (2.79 %) was significantly (P < 0.01) lower than the actual requirement of DMI 3.82 % during pregnancy. The average Metabolizable energy (ME) and protein intake were 1940 kcal and 45.2 gms which was significantly (P < 0.01) lower than the actual requirement of ME and protein intake of 2400 kcal and 58.6 g respectively, during late stage of pregnancy. Hence, the pregnant goats should be fed with adequate nutrients and twins carrying animals should be assessed for their BCS, blood glucose and BHBA to prevent the incidence of pregnancy toxemia disorder.
