Resumen
Trichobezoars (formations of hair balls that can not pass through the pyloric valve) are responsible of some of deaths observed in Angora rabbirs. A total of 160 trichobezoar deaths corresponding to 28.6% of total deaths were recorded during a reported period of five years. The highest mortality due to hair balls was recorded in 2001 (36.4 %) and was least in 1999 (9.4%). Of the four breeds, the highest trichobezoar death records were obtained in Russian Angoras and the lowest in German Angoras. Trichobezoars occur more frequently in winter months than other months. Besides trichobezoars, other causes of death recorded were pneumonia, suppurative pneumonia, peritonitis, rupture of stomach, gastroenteritis, cardiac failure and a small number of miscellaneous causes. In most of the cases, large, single trichobezoars were located in the stomach. The stomach contents of the trichobezoar deaths were mainly watery and scanty faeces and hard semisolid faeces. The ball obstructed the stomach occupying the opening of the pyloric valve. Pathomorphological lesions were noted in stomach, liver, lungs, heart and kidney.
