| The histological changes of the liver in ewes with pregnancy toxemia were characterized. Ten ewes were fed on grass ad libitum, and another ten were starved from day 130 of pregnancy for up to four days. Liver puncture biopsies were performed at days 70, 100, 130, and 140 of pregnancy, and at day 45 in postpartum. Seric hydroxybutyrate (HB), non-esterified fatty acids (NEFA), aspartate aminotransferase, and alkaline phosphatase were dosed. Histological preparations revealed similar incidence and intensity of mild liver steatosis in both groups at day 130. Starved ewes become toxemic (as indicated by HB), and at day 140 exhibited more severe injury in a higher proportion (9/9 vs. 4/10; P<0.01). Almost all of them (7/9) had large amounts of small lipid... |

| The aim of this study was to determine the effect of prepartum rbST injection on the metabolic profile of pregnant ewes induced to subclinical ketosis, as well as the metabolism until seven days of life and weight gain until seven weeks of life of the lambs. Twenty seven pregnant ewes of the pantaneiro genetic group were used, divided into two groups: rbST group (n = 14) and control group (n = 13). The rbST group received two applications of 1 mg/kg of rbST, at 97 and 111 days gestation, while the control group received placebo injections. There were significant differences between groups in levels of GGT in the ketosis post induction period and BHB concentrations in the postpartum period. Concentrations of glucose, urea, phosphorus, albumin, cholesterol,... |
