Key "takeaways" :
Keep tanks clean. Water odor, temperature, turbidity and color will determine intake.
Horses should drink 1 gallon of water per 100lbs or for a 1,000 lbs horse = 10 gallons per day. Preferably 10 to 15 gallons/day. A horse eating fresh grass (pasture) will require less water while a horse eating hay usually requires more water.
A mentally and physically thriving horse is usually given required amounts of forage, water, movement (turnout) and social interaction with conspecifics.
Bulmer, Louise S et al., 2019. High-starch diets alter equine faecal microbiota and increase behavioural reactivity. Scientific reports, 9(1), pp.18621–11.
The equine digestive tract is better suited to a high fiber-fat low starch diet. This type of diet results in healthier microbial populations within the intestines and results in a more settled pattern of behavior. Horses are designed to eat small amounts more frequently mimicking grazing/trickle feeding behavior.

For optimal performance of our equine partners we need peak physical fitness and a correct psychological state. Within that psychological state there are 3 components; Temperament, Mood and Emotional Reactions.

Kate Fenner is an Equine Scientist (BEqSc (Hons), Charles Sturt University), PhD candidate (Sydney School of Veterinary Science, University of Sydney), equestrian coach (Equestrian Australia and British Horse Society), horse trainer (John and Josh Lyons Certified Trainer). Kate has ridden, trained and competed in Dressage, Jumping, Western and polo in Australia, Europe, USA and Asia.
After years of experience starting horses for clients, Kate feels strongly that owners are best served by learning to train their own horses. As a result, she founded Kandoo Equine and has developed a series of ethical, easy to follow, step-by-step guides that are suitable for horses and riders of all levels.
She is currently completing her PhD on the development of the Equine Behavior Assessment and Research Questionnaire (E-BARQ).
Contact Information: firstname.lastname@example.org
Kate and Nancy discuss the benefits of the E-BARQ standardized tool for assessing horse behavior.. This application collects data on horse behavior, management and training. Horse behavior is a reflection of each horses' management and training. The platform is hosted by the University of Sydney.
We encourage every horse enthusiast, researcher, professional and practitioner to participate in E-BARQ!
Next week Kate and Nancy will be interviewing Kate Fenner who has worked on E-BARQ as her PhD project. She also owns Kandoo Equine. Check out her website or email us with questions you want us to ask her. www.kandooequine.com
Keith grew up 20 minutes from Louisiana Downs where Thoroughbred racing was the center piece for his family. He is a multiple stakes placed jockey with $2.4 million in earnings. As an actor he played Sham's jockey in the movie Secretariat. He was an Assistant Trainer for D.Wayne Lukas and Tom Amoss. He also spent time as an exercise rider for Mark Casse. This spring Keith became the Head Trainer for Man of Steel Enterprises, LLC. He currently has 4 starts, 3 wins and 1 third place finish.
Keith can be contacted via his FaceBook Messenger at Keith Andrew Austin.
Kate and Nancy discuss Equine Coronavirus as an emerging viral disease in adult horses and the parallels, it seems to exhibit, with our current human pandemic. (There is no evidence to indicate that horses could contract SARS-CoV-2 or that horses may be involved in the spread of SARS-CoV-2 to other animals or humans.)
*Out of 132/600 (2 to 4 years old) race horses that were exposed to equine coronavirus 22% were positive with symptoms (10% of these horses were reported to have GI symptoms).

Research Thesis (Phd): Uta Ulrike Von Borstel (2007). Fear In Horses and How It Is Effected By The Rider, Training and Genetics.
This study provides evidence that horses unaccustomed to being ridden in Rollkür prefer regular poll flexion rather than Rollkür. Horses were also more likely to exhibit behavior patterns indicative of discomfort or frustration when ridden in Rollkür than when ridden in normal poll flexion. This is supported with increased heart rates that reveal higher emotional arousal during Rollkür. Fear reactions were also stronger after being ridden in Rollkür versus normal poll flexion. These results suggest that Rollkür may compromise the horses welfare and impact rider safety.
The research we talk about this week is in relation to the following scientific paper:

Annual Conference, 2018, pp.522–525.
Next week we continue our discussion on fear based reactions in horses and riders by discussing the PHd thesis entitled "Fear in the horse and how it is effected by the rider, training and genetics. This will be a 3 part series. Author: Ute Ulrike von Borstel (2007).
We hope you join us! We appreciate each and every one of you!
Jarvis, N., Paradis, M.R., Harris, P. (2019) Nutrition considerations for the aged horse.
Equine Veterinary Education 31(2), pp 102-110.
Summary: "As the proportion of aged horses within the general equine population appears to be increasing in the UK and other developed countries, it is important to be aware of the changing dietary requirements associated with the aging process and age related diseases. This review provides guidelines for optimal nutrition of the older horse with practical approaches to improve or maintain body condition and support general health."
Listen in as Kate and Nancy discuss these guidelines and recommendations.

Obesity has been associated with insulin resistance in horses and ponies. This study seems to conclude that overweight sport horses and ponies are less likely to be hyperinsulinemic than sedentary horses and ponies.
Equine Metabolic Syndrome can be controlled through a management protocol of diet and exercise.
Points to note:
1. The cresty neck score is designed to assess the amount of fatty deposits in the horse’s nuchal ligament area. This assessment is independent of body condition score.
2. It is recommended that you use a combination of palpation and visualisation to obtain the score.
3. The characteristics of different breeds may influence your score. For example, you are likely to score a Draught horse higher than a Thoroughbred when they may in fact have the same degree of fat deposits.
Cresty Neck Score: (0 to 5 scale, 3 and above is considered problematic.)
0 - no crest or fat deposit present
1 - no visual appearance, but fat can be palpated.
2 - noticeable appearance of a crest, but fat deposited fairly evenly from poll to withers. Crest easily cupped in one hand and bent from side to side.
3 - Crest enlarged and thickened, so fat is deposited more heavily in middle of the neck than toward poll and withers, giving a mounded appearance. Crest fills cupped hand and begins losing side to side flexibility.
4 - Crest grossly enlarged and thickened, and can no longer be cupped in one hand or easily bent from side to side. Crest may have wrinkles/creases perpendicular to topline.
5 - Crest is so large it permanently droops to one side.
Cresty Neck Ratio: Circumference of middle of neck in inches (neck should be in a relaxed position) divided by Height in inches. (Centimeters can also be used)
If answer is greater than .63 in a horse or .68 in a pony it is time to take action to begin reducing that crest.
