Biochemical changes in serum and milk constituents during postpartum period in Saudi Ardy goats

Active Dry Yeast Culture Supplementation Effect on the Blood Biochemical Indicators of Dairy Goats

“…However, stronger fluctuations were observed in the control group than in the experimental one. The low level of glucose in both groups probably indicates a metabolic disorder, ketosis, which is a consequence of an imbalance of energy and protein in feed and, as reported by Amer et al [9], it has already developed at the end of pregnancy when malnutrition occurred. In study Amer et al [9], when the nutrient contents were above recommended level for goats, the average content of blood glucose was slightly above reference values (5.8 mg/l on days 7 and 28 of lactation).…”

The higher stability of blood glucose content in the experimental group in our study could mean that yeast supplementation slightly improves glucose metabolism, even when the goats are underfed.…”

“…A high level of TP indicates dehydration, inflammation, or chronic infection, while a low level indicates inter alia, intestinal malabsorption, liver disease, and losses through the kidneys. Moreover, a decrease in blood serum protein is caused by increased protein turnover due to stress [9] (http://www.9sites.org/pigcare/bloodwork.htm). The level of TP in the present study was at the lower limit of the reference value.…”

Plasma biochemical and minerals parameters in Arbia goats of a semi-arid region of North-Eastern Algeria during different stages of production

“…In this study, the total cholesterol plasma values were not significantly influenced by the physiological status of Arbia goats as was also found by ANTUNOvIć et al (2011a; 2011b) in ewes. However, in previous studies, the cholesterol level was higher in goats and sheep during late pregnancy (NAZIFI et al, 2002;BALIKCI et al, 2007;WAZIRI et al, 2010;IRIADAM, 2007), it decreased during the last 2 weeks of pregnancy, at 10 days post-partum (SKOTNICKA et al, 2011), at 7 days (AMER et al, 1999), and 21 days (IRIADAM, 2007); at 2 weeks of lactation (SADJADIAN et al, 2013), and it was higher in lactating than pregnant non-lactating does and even peaked on day 42 postpartum (SADJADIAN et al, 2013), or on 7 th day after parturition (WAZIRI et al, 2010). From our results we can deduce that the growing requirement for energy during lactation is well equilibrated.…”

“…There was no significant increase during these two periods compared to late gestation. AMER et al (1999) found that not all milk proteins are formed from the breakdown of plasma proteins but all major milk proteins are formed from free amino acid precursors in the blood. Moreover, the values of plasma total protein in our study were in the range of values reported by BAGNIKA et al 2014, KANEKO et al (2008), andSADJADIAN et al (2013).…”
