| Abstract |
This study was conducted to estimate the in vitro capacity of absorption and release of ammonium ion of 11 different types of Egyptian clays as alumino silicates and to study the effect of tafla clay in urea ration on some rumen and blood parameter of 12 Ossimi male lambs. The results showed that the different types of clays could be classified to three groups according to their capacity to adsorp ammonium ion. Tafla (Bilbis ) and bentonite (Alex.) classified in the group which have high capacity, while5 different types of kaoline showed the lowest capacity. Meanwhile, Aswan, bentonite and Fayoum River clays showed intermediate values . Also, the absorped ammonium ion increased by increasing clay level in the solution from 3 to 6 groups. From another point of view, four pelleted complete feeds were formulated which were 2%urea (U),2%urea plus 3% tafla (UT),2.5%urea plus 3% tafla (HUT) and the control feed without urea and tafla ( C).the ruminalNH3 -N showed higher(P< 0.01) values with U group than with UT and HUT groups at 1h up to 4h post feeding .no significant differences were detected in ruminal pH and TVFA,s values of tested feeds. However ruminal microbial protein improved with adding tafla than urea alone. Also, lambs fed urea plus tafla showed higher ( P< 0.01) heamatological parameters, blood glucose, and mineral contents ( Na, Cl, K and Ca ) and lower urea- N, and GPT than urea without talfa. The ion exchange capabilities of tafla clay make this natural alumino silicate attractive for use as a dietary supplements to prevent ammonia toxicity and improve N- utilization by rumen microorganism specially when relatively high level of NPN source are used in ruminant feeds.
Keywords: clay, ammonia adsorption, rumen and blood parameters.
