Abstract:

I studied diel activity patterns of female desert bighorn sheep ( Ovis canadensis mexicana) in the Little Harquahala Mountains, Arizona, July 1985-June 1986. Diurnal activity patterns were similar throughout the year. Nocturnal activity patterns were similar for all seasons except spring when activity significantly (P = 0.003) decreased. Bighorn sheep were active an average of 39 and 33% of any given hour during the day and night, respectively. Diurnal ambient temperatures and relative humidity were significantly (P ≤ 0.048) correlated with bighorn sheep activity during all seasons. Bighorn sh

Abstract:

Two experiments determined the effects of flaxseed supplementation on reproductive parameters in sheep. In experiment one, 240 multiparous Rambouillet ewes were assigned to one of two treatments: basal ration alone or basal ration with a Flaxlic® Sheep Tub offered over 35 days. Serum was collected weekly for progesterone (P4). Flaxseed supplementation did not improve progesterone concentration or reproductive parameters (P ≥ 0.26). In experiment two, 120 Rambouillet ram lambs were assigned to one of two treatments: basal ration alone or basal ration with a Flaxlic® Sheep Tub offered over 112 d

Abstract:

Data from two groups of lambs were analyzed. In group one, seasonal patterns of testis growth through 16 mo of age were assessed on 40 spring-born ram lambs (eight Barbados Blackbelly, 10 Suffolk and 22 1/2-Dorset, 1/4-Finnish Landrace, 1/4-Rambouillet). Scrotal circumference (sc) and body weight (wt) were measured at mean ages of 30, 62, 96, 124, 153, 180, 212, 243, 290, 333, 364, 398, 427, 454, 488 and 517 d. A multivariate repeated measures analysis indicated that there were breed differences in ram sc and wt measurements at each age. When logistic growth curves were fit to ram sc data, bre

Abstract:

Agriculture is the major source of food and livelihood in Sub-Saharan Africa, including Nigeria, employing about 3/4 of the population, and rural females play a significant role in agricultural production. Specifically, the participation ofwomen in small ruminant production in Nasarawa State in Nigeria is much higher than crop production and makes a significant contribution to their livelihoods. However, this sector is underperforming in the region because women, who are the dominant actors in the industry, lack the opportunities and the resources they require to make profitable investment in

Abstract:

Experiments were designed to determine: a) The effect of undernutrition in utero and in early post-natal life on subsequent activity of the hypothalamic-pituitary-ovarian axis in prepubertal and peripubertal female sheep; b) The effect of undernutrition in utero from the time of mating on development of the ovaries of foetal female sheep at days 47 and 62 of gestation. It is concluded that undernutrition in early life significantly retards pituitary development as demonstrated by the selective hypersensitivity of prepubertal L group pituitary glands but that this is compensated for around 18 m

Abstract:

The purpose of this thesis is to determine: 1) the consequences of nutritionally-mediated placental growth restriction on foetal growth, pituitary gonadotrophin gene expression and gonadal development at Days 77, 104 and 128 of gestation; 2) the effect of prenatal growth restriction on the subsequent onset of puberty in female and male lambs. Embryo transfer (ET) was used to achieve singleton pregnancies in peripubertal adolescent sheep. Immediately after ET, ewes were offered either a high (H, 2-2.5 x maintenance) or moderate (M, 1.25 x maintenance) level of nutrient intake until slaughter at

Abstract:

Chez les mammifères, les spermatozoïdes, au cours du transit à travers le tractus génital femelle, rencontrent des environnements qui influencent leur mobilité et leur pouvoir fécondant. L’analyse par spectrométrie de masse de ces milieux (plasma séminal, mucus cervical, fluides de l’utérus et de l’oviducte) a permis une caractérisation approfondie de leur protéome et l’identification de protéines modifiant l’activité des gamètes comme la Zinc Alpha Glycoprotein.

Dr. Eleine Mad är Madeleine Jacobsssons talesperson för dom vetenskapliga och paranormala upptäckter som uppstår i hennes världar. Hon beskriver innehåll, teknik och estetik utifrån ett kategoriseringssytem där konsten delas upp som olika typer av komponenter och därefter avkodas dessa allteftersom. För att förstå intuitionens inblandning i arbetsprocessen omförvandlas den till tre separata roller av en Sökare, Samlare och Myntare. Med rollerna försöker jag beskriva på vilka sätt som intuitionen är till gagn eller av förödelse för det konstnärliga arbetet. Sagan om M handlar om en grodlik ka

Abstract:

In mammals, millions of spermatozoa are deposited in the posterior female reproductive tract but only a few hundred reach the oviducts and from these only one will fertilise an oocyte in a mono-ovulatory species. Investigating why so few spermatozoa reach the oviduct and what was so special about these spermatozoa was the central theme to the studies reported in this thesis. The studies were conducted in the facilities of the Biomedical and Tropical Veterinary Science precinct, James Cook University and used Merino sheep as the model.

Abstract:

I proposed and tested the Interactive Risk Factors Hypothesis (IRFH), in which predation risk factors have an interactive (multiplicative) rather than an independent (additive) effect on vigilance while feeding. Four predictions were tested on adult female Dall's sheep (Ovis dalli dalli) in the wild: 1) Vigilance increases with decreasing group size, but the magnitude of this response becomes smaller as (a) distance to cliffs decreases, and/or (b) distance to obstructive cover increases. 2) Vigilance increases with increasing distance to cliffs, but the magnitude of this response becom
