Comparative species utilization and toxicity of sulfur amino acids.
Animal studies have shown that several methionine (Met) and cysteine (Cys) analogs or precursors have L-Met- and L-Cys-sparing activity. Relative oral bioavailability (RBV) values, with the L-isomer of Met and Cys set at 100% (isosulfurous basis), are near 100% for D-Met for animals but only about 30% for humans. Both the OH and keto analogs of Met have high RBV-sparing values, as does N-acetyl...
متن کاملthe effect of the utilization of electronic dictionaries on depth and breadth of vocabulary knowledge: a case of iranian efl learners
مطالعه حاضر تلاشی است برای بررسی تأثیرات به کارگیری فرهنگ لغات ، یکی از مهمترین ابزارهای یادگیری واژگان درفراگیری زبان خارجی، بر روی دانش لغوی. دراین تحقیق فرهنگ های الکترونیکی در قیاس با فرهنگ های چاپی مورد بررسی قرارگرفته اند که آیا این فرهنگ ها تاثیرقابل توجهی بر روی دوبعد کمی و کیفی دانش لغوی یعنی عمق و گستره لغات می گذارند. همچنین مشخص گردیده است که آیا تفاوت قابل ملاحظه ای میان عمق و گستر...

15 صفحه اولProtein and fat utilization in lactating sows: II. Challenging behavior of a model of metabolism.
The objective was to challenge the behavior of an existing mechanistic model of sow metabolism using data from a study that determined effects of fat and amino acid intakes on milk production, body and mammary composition in sows nursing 10 to 12 pigs. Sows were second through fourth parity; litter size was standardized at 12 pigs within 3 d of farrowing, and lactation was for 20 d. Diets were ...
متن کاملProtein utilization and amino acid digestibility of canola meal in response to phytase in broiler chickens.
The regression method was used in a 14-d broiler chicken study to determine the true ileal digestibility of amino acid (AA) and protein utilization in canola meal (CM, 388 g of CP/kg) without or with added phytase. Experimental treatments consisted of 2 factors, phytase at 2 levels (0 or 1,500 phytase units/kg) and CM at 3 levels (125, 250, or 375 g/kg). Birds received a standard starter diet f...
