1). Differences dependent on male or female presence.For females, there was a strong positive effect of male presence on fecal estrogens, fecal progestins, and vulva index (repeated-measures ANOVA, P < 0.0001). Extraction and assay of fecal hormones.Fecal steroids were made soluble in a modified phosphate-buffered saline containing 50% methanol, 0.1% bovine serum albumin, and 5% Tween 20 (polyoxy-ethylene sorbitan monolaurate, a surfactantBauman and Hardin 1998; DeMatteo 2004; Shindeler et al. on June 1, 2022. gladius profiles shadowlands; camra decathlon chasse; Although mature females do not require male presence to initiate estrus, male presence significantly shortens the interestrous interval. They are one of the smallest primates and have a soft, yet thick, coat of greyish brown fur. 1.2 The Code is based on the knowledge and technology available at the time of publication and may need to 150-250 grams with males being the heaviest. 1987). Red-flanked duiker Husbandry Best Practices. Although female bush dogs urine mark at a higher frequency than males (Kleiman 1972; Macdonald 1996; Porton 1983), individuals of both sexes demonstrate a higher urine-marking frequency when exposed to opposite- versus same-sex urine (Porton 1983). Extra food enrichment is not used with this species; however, we often use their diets in different ways as enrichment. 2004). A correlogram (Legendre and Legendre 1998) was generated for each female with each variable with male present and male absent. Bush babies are also characterized by the long upper portion of Split the diet in 2 portions with the first portion fed at 12 PM just before lights out and the second fed as late in the day as possible. Females often stay with their mothers longer. Sustained elevations in fecal progestins were considered to indicate ovulation. Height:5.1 to 7.8 in (male & female) This flexibility in the female's reproductive cycle may be associated with the lack of seasonality in such a broad prey base, that is, ability to obtain sufficient food throughout the year despite seasonal changes in availability of certain prey items. STANDARD OPERATING PROCEDURE #520 DOG Saint Louis Zoo, 1 Government Drive, St. Louis, MO 63110, USA (KED, UP, CSA), Saint Louis University, Department of Biology, 3507 Laclede Avenue, St. Louis, MO 63103, USA (KED). Subtle behavioral changes such as decreased appetite or activity or reluctance to train in expectant females may be a sign of impending labor or a sign of problems with labor or delivery. The most common housing arrangement at the DLC has been related female groups. At noon, when the white lights have gone out, we use a red light in the rooms for the keepers to see. They may give birth to 2 sets of twins a year. Around 10 months the young reach sexual maturity at which point males will emigrate. 2001; available at http://www.bio.umontreal.ca/Casgrain/R/index.html) to determine within and between correlations at the 2 levels (Fortin and Gurevitch 2001; Legendre and Legendre 1998). PURPOSE This Standard Operating Procedure (SOP) describes routine husbandry procedures for dogs. Procedures must be established for providing animal care during emergencies. The moving average (period = mean of 3 samples) for mean fecal estrogen and fecal progestin levels, and the 3-times-weekly vulva index for female 4. Bush dogs may also be housed in familygroups; in the wild , they are thought to live in groups in the wild.Although in the wild juveniles may remain with the family Identification numbers, including intemational studbook number (Dmoch 2004), for the 8 adult bush dogs used in this study. 2002). Seasonality of reproduction.Captive breeding records and behavioral research have shown that bush dogs in various environmental conditions do not have a single temporally specific annual breeding season as seen in temperate-latitude canids, but exhibit mating and births throughout the year (Kleiman 1968; Porton et al. 1992; Tate 1931; Wallace et al. Standardized practices allow easier detection of potential health and husbandry problems. An emergency medical plan must be in place to provide appropriate and timely veterinary medical care for any animal who is injured, in distress, or showing signs of illness. Previous behavioral studies with bush dogs have reported that during the period of female receptivity, Copulatory Locks (mean duration =15 min, range = 476 min) occurred 13 times per day over a period of 112 days (Drwa 1983; Kitchener 1971; Kleiman 1968; Porton et al. endstream endobj startxref Unlike other canids, the presence of a male was associated with shortened interestrous intervals and increased number of estrous cycles. . Asa and Valdespino 1998; Brady 1978; Kleiman 1968; Porton et al. 1987). Temperature and humidityAppropriate environmental conditions vary with the species of animal being housed. Web1 Introduction 1.1 This Code is intended as a guide for all people responsible for the welfare and husbandry of emus that are bred and/or reared in captivity. = 7, P < 0.01). Although no significant change was found for Fl (P = 0.2), this is believed to be a result of insufficient data, that is, a single, incomplete estrous cycle in the 2nd phase of the study, and not a result of her medical condition.
