In this session Dr. Garry Waghorn updated the membership on research pertaining to feeding fodder beet to cows. Some of the key messages include: Not all fodder beets are created equally; nutritional composition varies considerably. Feed testing is warranted. There are still a lot of unknowns when it comes to how fodder beet behaves within the rumen. Individual cows with rumen
There are 5 key points to success in lameness control: Record keeping – both incidence and type Early detection and prompt effective treatment Prevention of damage – cow flow and cow comfort Hygiene – low infection pressure Good horn quality and foot shape – good nutrition and genetics The main lesions for cows on pasture
Noemi shares work from her masters thesis about Johne’s disease in cattle comparing analysis from New Zealand and Germany. Some key themes from her work include: calving management needs to be more hygienic – ‘healthy’ milk is an essential culled animals should not end up “in the hole” clinically suspicious animals need to be examined
