Biotin dependency due to a defect in biotin transport.
We describe a 3-year-old boy with biotin dependency not caused by biotinidase, holocarboxylase synthetase, or nutritional biotin deficiency. We sought to define the mechanism of his biotin dependency. The child became acutely encephalopathic at age 18 months. Urinary organic acids indicated deficiency of several biotin-dependent carboxylases. Symptoms improved rapidly following biotin supplemen...
متن کاملOptimization of dry period in Karan Fries cow
AIM The objective of this study was to optimize dry period (DP) length that can maximize the production across adjacent lactations and overall lifetime yield. MATERIALS AND METHODS Performance records with respect to DP spread over a period of 15-year in Karan Fries (KF) cattle maintained at Livestock Research Centre (National Dairy Research Institute), were collected for the study. Data of 6...
متن کاملDiurnal variations in milk macro-mineral concentrations in Holstein dairy cows in Urmia, Iran
Milk samples from high and low milk producer Holstein cows, were obtained during the morning and afternoon milking over a one week period. Overall, 1064 samples were tested within 14 times sampling in Urmia, Iran. Milk macro-mineral concentrations in the morning milking and in low producers were greater than in the afternoon and in high producers. The highest and lowest concentrations were obse...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Effects of dietary biotin supplementation on performance and hoof quality of Chinese Holstein dairy cows
The objective of study was to determine the effects of supplemental biotin on lactation performance and hoof quality in dairy cows. Forty-five multiparous Chinese Holstein dairy cows (4076 d in milk) were randomly divided in three groups according to parity, previous lactation milk yield and days in milk. The experimental diets were identical for three treatments except for the level of biotin:...
