Milking procedures and prevalence of mastitis and mastitis specific-pathogens in selected smallholder dairy herds in Zimbabwe

A cross-sectional study was carried to collect milk samples for bacteriological examination and somatic cell counting in diary cows in Zimbabwe. Of the total animals tested, 172 (29.5%) had mastitis with 84% (144/172) of them having subclinical and 16% (28/172) clinical mastitis. The mean somatic cell count for culturally positive samples (738.1x103 ± 58.1) was significantly higher compared to that of negative samples (34.7x103 ± 2.8). Most of the farmers practiced normal milking routine although a few occasionally did not follow routine milking practices. Thus, the control of this type of mastitis should focus on measures to prevent animal-to-animal transmission.
Une étude d’échantillons représentatifs a été portée pour rassembler des échantillons de lait pour un examen bactériologique et un comptage de cellules somatiques des vaches laitières au Zimbabwe. De l’ensemble d’animaux examinés, 172 (29.5%) ont eu la mastite avec 84% (144/172) d’entre eux ayant la mastite sub-clinique et 16% (28/172) ayant la mastite clinique. Le compte moyen de cellules somatiques pour les échantillons culturellement positifs (738.1x103 ± 58.1) était sensiblement plus haut comparé à celui des échantillons négatifs (34.7x103 ± 2.8). La plupart des fermiers ont pratiqué la routine de traite normale bien qu’un petit groupe d’entre-eux parfois n’aient pas suivi de pratiques de traite routinières. Ainsi, la surveillance de ce type de mastite devrait se concentrer sur des mesures d’empêcher la transmission d’un animal à l’autre.

About the RUFORUM 2010 Biennal Conference
"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholders in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme of Animal Science"
