the role of russia in transmission of energy from central asia and caucuses to european union
پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولInteractions between forage and wet corn gluten feed as sources of fiber in diets for lactating dairy cows.
Twelve early lactation Holstein cows (4 fistulated) were used in replicated 4x4 Latin squares with 4-wk periods to determine the effective neutral detergent fiber (NDF) content of wet corn gluten feed and to measure the effect of forage particle size on ruminal mat consistency and passage rate of wet corn gluten feed. Diets were 1) 23.3% NDF (17.4 percentage units of NDF from alfalfa silage), 2...
متن کاملFactors Affecting Feed Efficiency of Dairy Cows
Feed efficiency (FE) is a concept that has gained popularity in recent years in the dairy industry. Monitoring FE is becoming a more common benchmark for monitoring the profitability of milk production relative to dry matter (DM) intake. In today’s markets, feeds and commodities are becoming more costly, which is driving the requirement for more efficient utilization to maintain profitability. ...
متن کاملEffective Fiber for Dairy Cows
Unlike other nutrients, such as protein and calcium, where requirements are provided in grams per cow per day for specific body weight and milk production levels, fiber “requirements” are merely minimum guidelines (NRC, 2001) aimed at maintaining normal ruminal pH, fiber digestion and milk fat test and preventing sub-acute rumen acidosis (SARA), laminitis and displaced abomasums (LDA). NRC (200...
متن کاملDefining Effective Fiber and Fiber Recommendations for Dairy Cows
Introduction Current NRC recommendations for dairy cattle provide only minimum recommendations for chemically measured fiber. However, physical characteristics of fiber can influence animal health, ruminal fermentation, animal metabolism, and milk fat production independently of the amount of chemically measured fiber. Using ground fibrous by-product feeds or finely chopped forages in rations t...
