Abstract

ABSTRACT Safaa Abd Allah Abd El-Monem Mohamed Hegazy: Productive and Immunological Performance of Ruminant Using Some Medicinal Plants as Feed Additives. Unpublished ph.D. thesis, Department of Animal Production. Faculty of Agriculture, Ain Shams University, 2022. This study was conducted in nutritional laboratory and farm of Animal Production Department Faculty of Agriculture, Ain Shams University at Shoupra El-Khema, Qalubia. This study divided into two stages, laboratory stage and field stage. Laboratory stage aimed to investigate the effect of experimental medicinal herbs with many doses on dry matter and organic matter disapperance and gas production emission to determine the best doses to use with field stage. Field stage, six trials was used to study the effect of garlic with doses 1 and 1.4, dill with dose 0.8, fennel 1.2 and marjoram 1gm/kg of ration DM compared control group, by using six experimental groups of Rahmani sheep to determine its effect on some rumen fermentation and blood biochemical parameters and nutrient digestibility. First stage (Laboratory stage) Four types of medicinal herbs, Garlic (Allium Sativium), Dill ( anethum graveolens), Fennel ( Foniculum Vulgare ) and Marjoram( Origanum majorana), with doses 0.6, 0.8, 1, 1.2, 1.4 and 1.6 gm /kg of ration DM used to evaluate the most effective doses to use with animals in field stage.
