Abstract

In order to describe the proportion and pattern of culling in commercial goatherds, this survey was carried out in an industrialized goatherd in Torbat-e-Jam, Iran, over a period of 18 years from 1996 to 2013. In total, the data of 3945 goats were used in this study. Finally, out of all samples, 499 (12%) goats were culled. The involuntary culling was performed mainly due to shortage disorders (3.8%), viral disorders (3.3%), microbial diseases (2.8%), and other disorders (2.1%). Sheep pox was the most important reason (64%) for culling due to viral disorders. Tick paralysis was the most common parasitic disease that contributed to culling and responsible for 88% of parasitic disorders. On the other hand, enterotoxemia accounted for 55% of microbial disorders is considered the most common cause of culling. The high proportion of culling due to shortage disorders, especially nutritional deficiencies should be considered the most important cause of culling. It requires precautionary measures and planning in order to reduce the aforementioned rate.

Caractérisation et Modèle de Réforme (abattage) chez les Chèvres

Abstract [French]

Afin de décrire la proportion et le modèle de l'abattage chez les chèvres commerciales, cette enquête a été menée sur une période de 18 ans, de 1996 à 2013, dans un chevrier industrialisé. Au total, les données de 3945 chèvres ont été utilisées dans cette étude. Dans l'ensemble, 499 (12%) chèvres ont été abattues. L’abattage involontaire était principalement dû à des troubles de pénurie (3,8%), à des troubles viraux (3,3%), à une maladie microbienne (2,8%) et à d’autres troubles (2,1%). En raison de pénuries, les désordres ont représenté 30% des dispositions des chèvres abattues. La variole ovine était la principale raison (64%) de l'abattage en raison de troubles viraux. La paralysie due aux tiques était la maladie parasitaire la plus courante ayant contribué à l'abattage. En moyenne, elle était responsable de 88% des troubles parasitaires. En revanche, l'entérotoxémie représentait 55% des troubles microbiens. La forte proportion de réforme due à des problèmes de pénurie, en particulier de carences nutritionnelles, doit être considérée comme une perte économique importante et des mesures de précaution sont nécessaires pour réduire cette perte.
