Publication Journal of Equine Veterinary Science
Finally, I can proudly announce the official publication of my Master Thesis work in the Journal of Equine Veterinary Science: Fecal pH and Microbial Populations in Thoroughbred Horses during Transition from Pasture to Concentrate Feeding. This research was conducted at the Massey University in New Zealand.
Abstract:
Abrupt dietary transitions and feeding of rapidly fermentable diets are common practices in the horse industry and have been associated with digestive and metabolic disorders that can impair the performance of horses. The present study investigated the effect of dietary transition from pasture grazing to confinement with concentrate feeding, and back, on fecal pH and bacterial populations of Streptococcus spp and Lactobacillus spp. Six Thoroughbred fillies, previously grazing perennial ryegrass and white clover-based pasture, were housed in individual stalls and fed an increasing ratio of concentrate to conserved forages for 13 days (days 1-13), followed by an abrupt transition back to only pasture-grazing for 3 days (days 14-16). The concentrate was initially offered at 0.83 kg dry matter (DM)/d and increased to 5 kg DM/d, whereas ensiled alfalfa was initially offered at 0.61 kg DM/d, increasing to 1.22 kg DM/d. Meadow hay was initially offered at 6.73 kg DM/d, decreasing to 1.6 kg DM/d. Fecal specimens were collected daily for determination of pH, and every 2 days for quantitative analysis of Streptococcus spp and Lactobacillus spp. Mean fecal pH increased significantly from pasture baseline values (pH 6.18) during the initial confinement and supplementation on day 1 (6.37), day 2 (6.52), day 3 (6.58), and day 4 (6.43) (standard error of mean [SEM]: 0.056; P < .001). By day 5, mean fecal pH values had decreased to, and remained at, baseline values until the horses returned to pasture, when another increase occurred at day 15 (6.45). Fecal colony forming units (cfu) of Streptococcus spp and Lactobacillus spp increased linearly (r = 0.94; P < .001) from 6.0 and 6.1 log10 cfu/g on day -4, to 7.8 log10 cfu/g on day 14 (SEM: 0.2 P < .001), respectively. Fecal cfu decreased on return to a pasture-only diet (P < .001). In this study, the increment of bacterial populations was associated with a relatively stable fecal pH and highlights the difficulty in identifying the effects of dietary transition on the equine hindgut health, without microbial culture.

Journal of Equine Veterinary Science (JEVS) is an international publication designed for the practicing equine veterinarian, equine researcher, and other equine health care specialist. Published monthly, each issue of JEVS includes original research, reviews, case reports, short communications, and clinical techniques from leaders in the equine veterinary field, covering such topics as laminitis, reproduction, infectious disease, parasitology, behavior, podology, internal medicine, surgery and nutrition. JEVS is also an official publication of the Equine Science Society.
Australian Horse Keeping Conference 2012
Living Legends Melbourne 12 /13 Nov 2012
Horse owners talk about weeds, dust, mud and emerging diseases. Scientists and natural resource managers talk about water quality, biodiversity and climate impacts. Yet we are all talking about the same thing.
The aim of this event is to bring a variety of people together to exchange knowledge about sustainable horse keeping practices from the researcher “down” and grass roots “up”!
MB Equine Services will be hosting a presentation on forages and enrichment for horses.

Curious horses
This week we started the forage pilot study, which is part of a honours students practical research work. Its only a small preference trial, but it will provide us with some valuable information for our later studies.
For this trial the student has to visit a number of horse properties and this week we started with the first two properties. The weather had been dry for the last 6 weeks but on the day that we wanted to start the trial – of course they predicted rain! So day 2 of the trial we spend most of the time in the rain with the horses. Nevertheless, the horses preformed even in the rain and showed their normal curiosity to all the visitors and foods we brought in!
PhD Equine Nutrition Project
Browsing – An overlooked aspect in horse management?
Throughout my Animal Management & Science degrees I have been involved in a number of animal nutrition studies- but I had a particular passion for equine nutrition! My last research project was for my Master Degree, which I conducted at the Massey University in New Zealand from 2005 to 2006. I studied the effect of abrupt dietary changes from pasture to confinement and concentrate feeding and vice versa on the faecal pH and microbiology of Thoroughbred horses. In 2006 I travel to Australia to present this work at the Australian Equine Science Symposium – which was a great opportunity to meet other new and renowned equine science and nutrition researchers. Since then I have been interested in continuing my research work in equine nutrition, but it has been very difficult to get something started (in Netherlands, Australia or New Zealand) – as equine nutrition is a topic that doesn’t generally get a lot of priority (it depends also on the topic within equine nutrition). Doing research with horses is also very expensive and there are not a lot of horse industry bodies with enough research funding – so I was not able to continue right away! However, being practically involved with the horse industry for the last 6 years has been a great experience and actually gave me more motivation to research a topic that can be applied to today’s horse management needs and that can improve the welfare of horses.
So in February of this year – I was able to finally start my PhD project on Equine Nutrition. The primary focus of the study is on forage enrichment for domesticated horses in Australia. I am particular interested in browsing behaviour and alternative forages. Although I am not able to give all the results during my research – I would like to keep our clients, readers and horse owners up to date with the progress and research events. On our MB Equine Services website I will regularly post some news about all the things that happen in the research field. So keep checking our website and facebook page or subscribe to our RSS feed!
We have published some educational articles in horse magazines that relate to this research topic. So if you would like to read those – visit our article database page.

Welcome to the New Website of MB Equine Services
Welcome to the new website of MB Equine Services. We found that it was time to update our website and make it more interactive for horse owners. We publish on a regular basis educational articles on horse nutrition, property design and pasture management in a number of horse magazines and we would like to notify our readers and new visitors/horse owners about our new releases. In addition, we have started our blog, which will feature information about our upcoming events (e.g. seminars, workshops, clinic etc) and in the field results and observations from our services. We will also publish regular posts on the progress of Mariette’s PhD equine nutrition project. More information about this interesting study will follow soon.
We hope that this website is more user friendly and we will do our best to keep improving it. Happy browsing!
