| A study was conducted in Ruminant Research Station/Public Authority for Agricultural Research/Ministry of Agriculture. The experiment lasted for 93 days. twenty crossbred growing male goats weighted 21.7 ±0.91 kg and 7-8 month old were used in the study, the goats were equally divided into five groups (4 animals/treatment) received the dietary treatments were as follows:T1:Concentrated diet without ground dates stone ,T2:Concentrated diet contain 30% ground dates stone and 0.08% urea,T3:Concentrated diet contain 30%ground dates stone and 1.20% urea,T4:Concentrated diet contain 30% ground dates stone and 5.8% Soybean meal, T5 Concentrated diet contain 30% ground dates stone and 7.8% Soybean meal, animals were fed concentrate at 2.5% of body Weight, alfalfa hay was given on an ad libitum basis as the roughage, It was found that: here were significant increase (P<0.05) in rations content 30% dates stone in rations content soybean meal than rations content urea regarding rumen pH during periods 0,3 and 6 hrs of morning feeding, significant increase (P<0.05) in rations 1 and 5 in rumen pH during periods 3 hrs and in ration 1 during periods 6 hrs, Ruminal ammonia-nitrogen (NH3-N) increased (P<0.05) in rations contents 30% dates stone than rations not content dates stone during all periods, significant increase (P<0.05) in soybean meal rations than rations content urea during all periods, significant increase (P<0.05) in ration 5 with interaction during periods 3 and ration 4 and 5 during periods 6 hrs of morning feeding compared with treatment groups. The Results indicated significant variations (P<0.05) in volatile fatty acids, where the higher concentrate value (acetic, propionic and butyric acids) in ration contents 30% dates stone than rations not content dates stone, significant increase (P<0.05) in acetic acid with rations content soybean meal than rations content urea, While the higher value of acetic acid in T3 ,T4 and T5, Propionic acid in T5, higher value of Butyric acid in T2,T3,T4 and T5. While protozoal populations were significant Increased (P<0.05) in goats fed T5 in the comparision with other treatments. | ||
