Postnatal hypoglycemia and blood glucose concentrations in neonatal tropical goat kids.

Abstract

This study aimed to evaluate the influences of breed, sex, litter size, and birth weight on the incidence of postnatal hypoglycemia and blood glucose concentrations in neonatal tropical goats. A total of 160 neonatal goat kids belonging to Red Sokoto (n&#xa0;=&#xa0;98), Sahel (n&#xa0;=&#xa0;40), and West African Dwarf (n&#xa0;=&#xa0;22) breeds, were categorized after birth based on glycemic status, sex, litter size, and birth weights (high or low). Blood samples were collected on postnatal days 0, 1, 2, 3, 10, and 20 to determine blood glucose concentrations. Results revealed that the incidence of hypoglycemia at birth among neonatal goat kids was 22.5% (36/160) and was significantly (P&#xa0;<&#xa0;0.05) higher in the Sahel breed kids, twin kids, and kids born with low birth weights. After 24&#xa0;hours, all hypoglycemic kids became normoglycemic but maintained lower (P&#xa0;<&#xa0;0.05) blood glucose levels than those that were normoglycemic at birth, until day 10, when both groups had comparable blood glucose levels. In all groups, blood glucose concentrations increased significantly 24&#xa0;hours postnatal, and kids with high birth weights had significantly higher values than those with low birth weights, while the buck kids had higher values than the doelings. There was a negative correlation (r&#xa0;=&#xa0;-0.31; P&#xa0;<&#xa0;0.0003) between the blood glucose concentration of dams and those of their kids. In conclusion, the incidence of hypoglycemia in tropical goat kids was markedly influenced by breed, birth weight, and litter size. Furthermore, the hypoglycemic kids maintained lower blood glucose concentrations until day 10 postnatal, suggesting the need for relevant nutritional provisions for hypoglycemic kids during this critical period.
