Ingestion of indigestible foreign bodies in both domestic and wild ruminants are very common. Indigestible foreign materials can be ingested during free range grazing or under captivity in zoos or game parks. There are different types of bezoars in literature. The most common in animals are phytobezoars, trichobezoars, lactobezoars, phytotrichobezoars, lithobezoars or pharmacobezoars. This is a case study of an adult (4 years old), 40 kg body weight female Fallow Deer (Dama dama) which was reared with other four more Fallow Deer does at Riyadh Zoological Garden. The doe was found sluggish and weak. On presentation the veterinarian of the zoo noticed the anorexia, pale mucous membranes and dullness. There was Normocytic Normochromic anaemia, low RBCs and Haematocrit level, high neutrophil count and leucocytosis. The doe was subjected to medicinal and supportive therapy but she could not recover and found dead on very next day. On post-mortem examination, an unusual large polythene bezoar along with calcified stony mass recovered from the rumen. The results suggested that the rumen impaction in the Fallow Deer might be due scavenging on refused Plastic dumps in the premises left over by visitors to the zoo and that the blood biochemical alterations, alongside clinical signs, might be of some diagnostic assistance.

D airy farmers introduce highly productive animals (exotic breeds), but the environmental condition of the area (Pakistan) cannot allow them to attain their peak production that limit the farmers dream on their feasibility report (Rashid et al., 2018). Intestinal parasites are the major constraints for economic losses in productive animals at dairy farms. They cause anorexia, anemia, retarded growth, weight loss, delayed sexual maturity, low productivity (milk and meat) and increased susceptibility of animals to other infections (Yadav et al., 2004). Gastrointestinal parasitic problem is the worldwide (Regassa et al., 2006). Ruminants gastrointestinal nematodes of cattle includes, Trichuris, Haemonchus, Oesophagostomum, Bunostomum, Ostertagia, Trichostrongylus, Cooperia, Capillaria (Hosking et al., 2008). The reported prevalence of helminths in Pakistan ranges from 33.68-51% (Khan et al., 2010). The use of broad spectrum anthelmintic of benzimidazole (albendazole) group was evaluated its effect on milk production, body condition score and eggs per gram (EPG). Reported albendazole efficacy against Ostertagiaostertagi, adult, DL4 and EL4 is 99.00, 95.50 and 84.90%, respectively. The current study was performed on a Holstein Friesian cattle with the history of decrease production, diarrhea and weight loss with anorexia. The studied animal was purchased from local market. Fecal samples from normal and infected animals were taken for the diagnosis of anthelmintic, its efficacy and effect on milk production and body condition score for a period of one month. The normal animal was dewormed with albendazole one month
