Non-perforating abomasal lesions in veal calves

Non-perforating abomasal lesions in veal calves,  styczeń 2010 r. : The objective of study was to assess the prevalence of             pyloric and fundic abomasal lesions in Swiss veal calves at             slaughter and to compare the occurrence of non-perforating             abomasal lesions between two different production programs             'Naturafarm' and             'conventional'.             'Conventional'-production             settings met the minimal standards as defined by the Swiss             animal welfare legislation, whereas             'Naturafarm' production             complied with increased animal welfare requirements. A total             of 125 abomasa were randomly selected in one large abattoir.             They were examined macroscopically, and the occurence of             lesions in either the fundic or pyloric region of the             abomasum was recorded separately. Animals raised in the             'conventional'-             production setting revealed a significantly higher prevalence             of lesions in the fundic part. Factors significantly             affecting the prevalence of non- perforating lesions in the             fundic part were the             'conventional'-production             environment, including missing access to an outside pen,             missing access to water and straw as the only roughage,             feeding by bucket and the liquid milk by-product Protofit in             combination with the powder Sprayfit.
