Relative Traffic Tolerance of Warm-Season Grasses and Suitability for Grazing by Equine.

Warm season wear-tolerant turfgrasses, such as those used on golf courses and athletic fields, may be valuable forages on equine operations because of their potential to remain viable during heavy hoof traffic. Crabgrass may also be suitable as it thrives in conditions where other grasses have limited success. The objective of this study was to assess the relative traffic tolerance and nutritional composition of five warm-season (WS) turfgrass cultivars of bermudagrass and zoysiagrass and one WS forage-type crabgrass.

Characterization of the Prevalence and Management of Over-Conditioned Ponies and Horses in Maryland.

It has been estimated in the United States and abroad that 20%-51% of the equine population suffers from over-conditioning or obesity. The objective of this study was to evaluate the prevalence of over-conditioning in the equine population in Maryland, to characterize weight control measures used, and to ascertain how control measures impact the operation. Over-conditioning was defined as a body condition score of 4 or 5 on a 5-point scale.

Relative Traffic Tolerance of Cool-Season Turfgrasses and Suitability for Grazing by Equine.

Unlike traditional forage grasses, turfgrasses, which were developed to be tolerant of foot traffic and close mowing, may be suitable as alternative ground cover in areas of high hoof traffic such as dry lots. The objective of this study was to evaluate the potential of eight cool-season turfgrasses as alternative ground cover in heavy use areas. Cultivars were established via seeding in four replicated plots.

Effects of grazing system, season, and forage carbohydrates on glucose and insulin dynamics of the grazing horse.

Rotational grazing is a recommended practice for grazing livestock, but little is known about its benefits with respect to grazing horses. The objective of this study was to investigate the effects of continuous (CON) and rotational (ROT) grazing on forage nutrient composition and whether those concentrations influenced circulating glucose and insulin concentrations in the grazing horse. Twelve mature Standardbred mares were paired by age and weight and randomly assigned to 1 replicate of either a 1.

Fibre digestibility, abundance of faecal bacteria and plasma acetate concentrations in overweight adult mares.

The purpose of the present study was to compare digestibility of grass hay, faecal and plasma volatile fatty acid (VFA) concentrations, and faecal bacterial abundance in overweight and moderate-condition mares. Five overweight adult mixed-breed mares and five adult mixed-breed mares in moderate condition were housed individually and limit-fed orchard grass (Dactylis glomerata) hay at 20 g/kg body weight (as fed) daily for 14 d. Forage DM and fibre digestibility were determined using AOAC methods; digestible energy was measured using bomb calorimetry; plasma and faecal VFA concentrations were determined by use of GC and MS; faecal Firmicutes, Bacteroidetes, Fibrobacter succinogenes, Ruminococcus flavefaciens and total bacteria abundance was determined by quantitative real-time PCR using previously designed phylum-specific 16S ribosomal RNA gene primers.

Antioxidant status in elite three-day event horses during competition.

The objective of this study was to determine if competition intensity would have an effect on antioxidant status in horses before and during a three-day event. Body weight, body condition score, and blood was sampled from CCI2* (n = 19) and CCI3* (n = 23) horses before the start of dressage, 20 to 30 min following cross-country, and 18-24 h after cross-county. Data were analyzed using a PROC MIXED in SAS.
