  This paper deals with egg output of Paramphistomata in dairy cattle. Six dairy cattle, four Chinese Holstein and two Simental cows whose ages were 4.1, 6.4, 6.8, 7.3, 7.8, 9.1 years, were examined. Total egg amounts of Paramphistomata were calculated in total fecal quantity of a cow per day. The results were 1.8×106, 4.1×106, 1.8×107, 9.0×106 , 1.5×107 and 4.3×105 eggs. Dissection was used to collect paramphistomata samples from rumen, omasum, rectum and cecum of the six dairy cows completely. The results were that total worm numbers were 1660, 1180, 5047, 3115, 4463 and 132 showed that egg output of paramphistomatata were 1084, 3458, 3524, 2907, 3360 and 3258 per worm per day, respectively. The average egg output was 2932 eggs/worm/day. On the other hand, the slide samples of 371 paramphistomatata worms from the six autopsied cows were identified f.. View More»
