Приложение на системата за нето оползотворяване на енергията и протеина чрез индексите Кларкове в млечното говедовъдство
Димо Пенков, Ганчо Ганчев, Милена Михайлова
Резюме: Адаптирана е методика за изчисление на нето оползотворяването на енергията и протеина по веригата „фураж – краве мляко“ чрез използването на критериите Кларк на енергийна дистрибуция (КЕД) и Кларк на протеинова трансформация (КПТ). За основа са ползвани данни от опит с елитни крави от породата Българско Черно-шарено говедо през първите 100 дни от лактацията.
Получените КЕД (средно 0.5766 с варирания по периоди между 0.5275 и 0.6178) и КПТ (средно 0.9104 с варирания по периоди между 0.8324 и 0.9984) отразяват най – високите трансформации на нето енергия и протеин смилаем в червата от фуража в бруто енергия и суров протеин на директно консумируем от хората продукт в сравнение с други продукти от домашни животни.
Ключови думи: Кларк на енергийна дистрибуция; Кларк на протеинова трансформация; млечно говедовъдство
