	Title	Sperm competiton and variation in zebra mating behaviour			Type	Journal Article
	Year	1990	Publication	Behavioral Ecology and Sociobiology	Abbreviated Journal	Behav. Ecol. Sociobiol.
	Volume	26	Issue	6	Pages	427-434
	Keywords
	Abstract	Data are presented on the breeding behavior of two zebra species to test whether intra- and interspecific variation in male reproductive behavior and physiology are correlated with differences in female promiscuity. In one species, plains zebra (Equus burchelli) females live in closed membership single male groups and mate monandrously. In the other species, the Grevy's zebra (E. grevyi) females live in groups whose membership is much more temporary. Typically, associations with individual males are brief and mating is polyandrous. However, some females – those having just given birth – reside with one male for long periods, mating monandrously. These differences in female mating behavior generate variability in the potential for sperm competition. We show that behavioral differences in male investment in reproductive activities correlate with the potential for sperm competition. When mating with promiscuous mares, Grevy's zebra stallions made a greater investment in reproductive behavior (calling, mounting, ejaculations) than did stallions of either species when mating with monandrous females. The evolution of large testes size in the Grevy's zebra, when compared to the congeneric plains zebra, horse, and mountain zebra, allows for this increased investment.

	Title	Bedding material preferences of ponies.			Type	Journal Article
	Year	1989	Publication	Journal of American Society of Animal Science	Abbreviated Journal	J Anim Sci
	Volume	67	Issue	8	Pages	1986-1991
	Keywords
	Abstract	The bedding preferences of ponies were determined using video recordings of nighttime (1900 to 0700) behavior of individually housed ponies. The ponies' behavior each minute was recorded to determine time budgets. In Exp. I, preference for bedding was determined using three mares, three stallions and two geldings given access to bedded and unbedded areas in a box stall. The ponies spent more time (66%) on the bedded area and were never observed lying on the unbedded areas. In Exp. II, three mares and six stallions were given access to a box stall, one side of which was bedded with wood shavings and the other with straw. Although some individual animals preferred one bedding over the other, neither form of bedding was preferred consistently. Time budgets in Exp. II were similar on both bedding materials. The ponies spent 12% of their nighttime lying, 2% walking, 35% eating and 50% standing inactively. Some ponies had a relatively strong preference for bedding, but the type of bedding preferred varied with the individual animal. Some individual ponies had no clear preference, but instead had a side or position preference

	Title	*Factors determining the digestive efficiency of the domesticated donkey.(Equus Asinus Asinus* )**			Type	Journal Article
	Year	1989	Publication	Q J Exp Physiol	Abbreviated Journal	Q J Exp Physiol
	Volume	74	Issue	1	Pages	1-6
	Keywords
	Abstract	Factors determining the digestive efficiency of donkeys were studied in animals fed either a low quality roughage (wheat straw: 77{middle dot}1% neutral detergent fibre, 2{middle dot}8% crude protein) or a high quality forage (alfalfa hay: 47{middle dot}5% neutral detergent fibre, 22{middle dot}7% crude protein). The neutral detergent fibre (NDF) intake when fed wheat straw was 1693 {+/-} 268 g animal-1 day-1, 10% higher than when fed alfalfa hay. Digestive coefficient of NDF and acid detergent fibre (ADF) when fed wheat straw amounted to 50{middle dot}9 {+/-} 4{middle dot}9 and 42{middle dot}0 {+/-} 4{middle dot}1% respectively. NDF and ADF apparent digestibilities and mean retention times (37{middle dot}7 {+/-} 1{middle dot}7 and 36{middle dot}4 {+/-} 3{middle dot}2 h respectively) were not significantly different (P [rang] 0{middle dot}05) between the two diets. The donkey appears to digest cell wall constituents as efficiently as the Bedouin goat when on low quality roughage, but less efficiently when fed alfalfa hay. Its energy digestibility is, however, as high as that reported for the Bedouin goat. The donkey's high energy digestibility is related to its capacity to digest soluble food components more efficiently than the ruminant. The mean retention time in the donkey is shorter than in the Bedouin goat and is consistent with its capacity to compensate for a lower quality diet by increasing its intake rate. Recycling of urea in donkeys maintained on wheat straw amounted to 75{middle dot}5 {+/-} 13{middle dot}0% of the entry rate. A decrease in the rate of renal urea filtration, coupled with an increase in the fraction reabsorbed, increased the retention of nitrogenous waste and permitted recycling of nitrogen into the gut.

	Title	Urinary steroid evaluations to monitor ovarian function in exotic ungulates			Type	Journal Article
	Year	1990	Publication	Zoo Biology	Abbreviated Journal	Zoo Biol
	Volume	9	Issue	5	Pages	341 - 348
	Keywords	Perissodactyla – ovulation – corpus luteum
	Abstract	A direct enzyme immunoassay (EIA) for non-specific urinary progesterone (Po) metabolites, utilizing a non-specific monoclonal antibody against pregnanediol-3-glucuronide, was evaluated for the purpose of assessing luteal function in equids. Urinary pregnanediol-3-glucuronide (PdG) and immunoreactive PdG-like conjugate (iPdG) concentrations, indexed by creatinine, were compared to plasma Po concentrations in non-conceptive ovarian cycles through two ovulations in four mares. High-performance liquid chromatography (HPLC) of urine from lutealphase mares and a pregnant zebra revealed an absence of significant concentrations of PdG and the presence of at least three immunoreactive compounds, all of which were more polar than PdG. The concentration of iPdG in the mare ranged from a nadir of approximately 3 ng/mg Cr at the time of ovulation to nearly 400 ng/mg Cr at the mid-luteal-phase peak and paralleled plasma Po concentrations. This non-radiometric assay for iPdG permits the assessment of ovulation, luteal formation and function, and luteolysis in unprocessed urine samples from domestic mares. Data from a single zebra indicate this approach also will permit simplified and non-invasive longitudinal studies of ovarian function among a wide range of Equidae.
