Dr Megan Abeyta recently completed her PhD under the supervision of Lance Baumgard focused on the impact of inflammation. To set the scene, Dr. Abeyta outlines the importance of the GIT in every animal. With 70% of the immune system located in the GIT, any damage to the protection barrier throughout the track can lead
Management for improved fertility and lifetime productivity in grazing dairy cows: latest NZ research – Claire Phyn, Dairy NZ
Claire Phyn, senior scientist at DairyNZ presented about an 8 year research programme funded by MBIE and NZ dairy farmers through DairyNZ Inc. It aimed to provide management and genetic solutions to improve cow health, fertility and longevity. Claire reported about 1. Effect of carbohydrate type (starch vs fibre) on reproduction 2. Hyperketonaemia (subclinical ketosis) and 3. Feeding synthetic zeolite pre-calving
Analytics is the next scientific breakthrough.
This presentation covers the potential for protein supply, feed quality and bio-active forages to reduce reliance on anthelmintic drenches.
In the 1970’s in mid-west US, most cows were kept in tie stall barns where physical contact between cows and the spread of M bovis were very limited. The death rate of young calves was reduced with the move to individual hutches and no physical contact, and pasteurising milk. In the 1980’s if mastitis didn’t
Mycotoxins exist as they compete for advantage over other micro-organisms. In doing so they weaken plant cells, animal tissues and the host’s internal defence mechanisms.
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
