to evaluate the effects of garlic on some blood metabolites in pre-partum dairy goats, the ration was supplemented with raw garlic at the doses of 0, 30, 50 and 70 g kg-1 of dry matter (dm) in eight pregnant mahabadi breed goats (59 ± 1 kg initial live weight) in a replicated latin square design during the last two months of pregnancy. each experimental period lasted 14 days with the first 12 d...

reproductive efficiency in dairy cattle has been decreased over the last 5 decades despite significant gains in genetic selection, improved reproductive technologies and nutritional care. in high-yielding dairy cattle, the negative energy balance (neb) during the first week post-partum adversely affects ovarian activity, mainly follicle growth and steroidogenesis. circulating levels of non-este...

The composition of plasma non-esterified fatty acids was investigated during glucose tolerance tests to determine changes in individual fatty acid concentrations after glucose administration and to determine whether differences existed between the individual fatty acid concentrations of maturity-onset diabetic and non-diabetic men. The mean fasting total nonesterified fatty acid concentration o...

Background: Evaluation of energy metabolism indices in mid-lactation Holstein cows is critical to monitor health status. Aims: The objective of this study was to assess the effects of low (≤0.75) vs. high (>0.75) drops in body condition score (BCS) until day 60 post-partum on energy metabolism indices during mid-lactation in Holstein cows. Meth...

We describe a relatively rapid radiochemical assay for determining plasma non-esterified fatty acids, by use of a Dole-type (J. Clin. Invest. 35: 150, 1956) extraction and formation of 57Co soaps. Results correlated well (r = 0.957) with those by gas-liquid chromatography. The between-batch CV for 1.12 mmol of non-esterified fatty acids per liter was 7%; the sensitivity is estimated to be 22 mu...

HOLLENBERG, C. H., AND A. ANGEL. Relation of fatty acid structure to release and esterijication of free fatty acids. Am. J. Physiol. 205(5): 909-912. I g63.-After incubation of rat adipose tissue with corticotrophin in buffer-albumin, the composition of the free fatty acids (FFA) in the tissue and in the medium was determined; the medium contained proportionately more myristic, palmitoleic, lin...

abstract         background and objective: the relationship between diabetes mellitus and increased risk of cardiovascular diseases has been demonstrated. the aim of this study was to determine the fatty acid profile of epicardial adipose tissue in diabetic and non-diabetic patients with cardiovascular disease.          methods: in this study, 28 diabetic and 40 nondiabetic patients were evalua...

background: the modern dairy cows, due to intensive selection for higher milk production during past decades, have become more resistant to insulin. accompanied with dmi depression in per parturient dairy cow, insulin resistance may lead to a massive release of non-esterified fatty acids (nefa) to bloodstream which might act as a start point for development of other diseases. objectives: the pu...
