Status In Nature And Threats

The giant panda is endemic to the mountains of Sichuan, Gansu and Shaanxi Provinces in China. The species is now found in only six mountain ranges at the eastern edge of the Tibetan plateau, distributed in as many as 30 to 40 distinctive populations (Fig. 1.2 Plate I). The Min Shan Mountains are the heart of panda numbers and activities, probably sustaining half the remaining wild individuals (Lumpkin & Seidensticker, 2002). Historically, the species was widely distributed and may have...

Refroductive Hormone Patterns

Average peri-oestrual endocrine profile Mean urinary oestrogen in a representative female (SB 112 1987 to 1991), with superimposed reproductive behavioural data during the peri-oestrus interval are depicted in Figure 8.1. Oestrogen concentrations increased slightly by Day 12 (7 2 ng mg 1 Cr), were eight-fold above baseline (19 3 ng mg 1 Cr) by Day 6, remained at that level for four days and then peaked on Day 0 (63 5 ng mg 1 Cr). Oestrogen excretion then declined, returning to baseline by Day...

Gastric lumen, with flecks of white mucoid debris throughout, which prevented good viewing of the gastric mucosa in three individuals (SB 387, 522 and 530). In each of these cases, there was also an ingesta mass in the pyloric antrum that prevented observations and penetrating the pyloric with the endoscope. Each of these pandas had undergone minimal fasting and water removal before anaesthesia, which apparently contributed to this difficulty. No technical challenges occurred in the remaining...

Priorities For The Future

Because our studies are longitudinal and long-term, so far we have incomplete data for making definitive conclusions about the impact of early weaning and hand-rearing on long-lasting social and behavioural competency in the giant panda. It has been standard practice in Chinese breeding institutions to wean a giant panda cub permanently from its mother at least one year earlier than weaning occurs in the wild. Certainly, removing a cub at a younger age reduces the interbirth interval by...

Value Of Giant Pandas Ex Situ

If giant pandas should be maintained in captivity then the role of that population in conservation needs to be clearly articulated. Given that we can adhere to a goal whereby the ex situ population is not a detriment to the wild, but rather an advantage for 'enhancement' of giant pandas in nature (Zheng et al., 1997), then we recognise at least six ways in which the captive population of giant pandas is of conservation value. 1. Ambassadorial value. Few people have been fortunate enough to see...

And Physiology

The giant panda is an enigmatic carnivore, adapted to a highly specialised ecological niche (see Chapter 1). Although the species looks, moves and is genetically similar to bears (see Chapter 10), many of its pheno-typic traits are unlike those of other ursids. For a thorough understanding of the anatomy of giant pandas, the reader is referred to the classic publication of Davis (1964). Many of the species' distinctive features are related to its highly specialised reliance on bamboo. For...

Overview Of Ultrasound Health Assessments Of Male And Female Giant Pandas

Ultrasound examinations have been conducted since 1997 in the male and female giant panda at the Berlin Zoo, with and without anaesthesia. Anaesthesia induction was achieved with ketamine hydrochloride (10 mg kg-1 body weight, BW) administered via blowpipe dart injection. Anaesthesia was then maintained using isoflurane gas delivered via a face-mask (2.5-3.0 volume percentage with oxygen flow of 2-4 l per minute). Transabdominal assessments were carried out using a portable ultrasound unit...

The science of behavioural management creating biologically relevant living environments in captivity

Ronald r. swaisgood, guiquan zhang, xiaoping zhou, hemin zhang As for many highly specialised carnivores, breeding giant pandas in captivity has had sporadic gains and setbacks over its 40-year history (see Chapters 1 and 19). Although many husbandry issues have been addressed successfully, we are still learning about behaviour and its relevance to ex situ management. This chapter updates the state of captive breeding at the China Conservation and Research Centre for the Giant Panda in the...

Methods

The behavioural specialist on the Biomedical Survey team used a standardised form (Table 5.1) to collect relevant health and reproductive histories on every giant panda from senior keepers and or managers at all four institutions. These data were relevant for establishing a baseline on health and reproductive history for each individual as well as ascertaining early rearing information. To ensure consistency, one person (with a Chinese translator) collected all information. As a complementary...

Methods For Gastrointestinal Endoscopy

Eleven giant pandas (four males and seven females) were evaluated and ranged in age and weight from nine months to 19 years and 19 to 165 kg, respectively. Effective endoscopy of the gastrointestinal tract requires proper patient preparation. The presence of ingesta and faecal material can inhibit entry into the oesophagus, stomach, duodenum and colon, contribute to damaged tissue or instrumentation and prevent clear visualisation of luminal surfaces. For companion animals (dogs and cats), a...

Results And Discussion

Ketamine HCl was used without any additional sedative drugs on 44 occasions (mean 5.7 mg kg-1 range 4.1-8.8 mg kg-1 mean time to induction 10.3 minutes range 1-58 minutes). The total procedure length averaged 43 minutes (range 28-144 minutes) with a total accumulated ketamine dose averaging 9.1 mg kg-1 (range 4.2-16.7 mg kg-1). In the remainder, ketamine was the primary agent but chlorpromazine, xylazine or diazepam was also used (see p. 60-61). In general, relaxation was poor with ketamine HCl...

Restraint And Anaesthesia

Operant conditioning can be used to train giant pandas to enter and remain quiet in a restraint device. The steel-constructed restraint cage used at the San Diego Zoo is rectangular (2 m long by 93 cm wide by 118 cm high) (Fig. 15.1) and on wheels for mobility. It has a solid bottom with bars on the sides and top. Along one side, some of the bars are removable to allow better access to the animal. The opposite wall is moveable allowing the available internal cage space to be decreased (i.e. the...

The Giant Panda Biomedical Survey how it began and the value of people working together across cultures and disciplines

David e. wildt, anju zhang, hemin zhang, zhong xie, donald This book deals mostly with new biological knowledge and the use of that knowledge to benefit the giant panda by enhancing health, reproduction and management. It is an important strategy for modern-day zoo scientists, conducting 'basic research' to learn as much as possible about previously unstudied phenomena in any species, especially those that have received little, if any, attention. In many ways, a scientist affiliated with a zoo...

The Diseases By Organ System

Digestive disorders represent by far the most prevalent and chronic form of disease in captive giant pandas (Bush et al, 1985 Goltenboth, 1985a,b Villares et al., 1985 Pan et al., 1991 Gual-Sil et al., 2000 F. Ollivet, unpublished data, pathology report, Paris Zoo). Gastrointestinal disease is the leading reported cause of death in captive pandas and also maybe so in free-ranging counterparts (Qiu & Mainka, 1993). Cubs often develop bouts of diarrhoea within the first month of life,...

Giant Pandas In The Western World

The giant panda was virtually unknown outside China until the 1800s when the declining Qing Dynasty opened China to western trade. The species was first described in the western world by the missionary naturalist and explorer Pere Armand David who described a giant panda specimen shot by Chinese hunters in Baoxin County, Sichuan Province in 1869 (Hu & Qiu, 1990). It was not until 1916 that the first westerner, Hugo Weigold, saw a live giant panda, and then it was another 14 years until the...

Medical Management Of The Geriatric Giant Panda

The giant panda has the capacity to have a relatively long lifespan in captivity, up to almost 30 years. Since reproduction generally ends after 20 years, we consider animals beyond this age to be 'geriatric'. Conditions that have been recognised in the aged panda include osteoarthritis, renal insufficiency, epistaxis, hypertension and dental disease. However, information available for each of these problems is often limited to studying a single individual. This is because few geriatric giant...

The giant panda also produces a smaller litter mass relative to maternal body mass than, for example, the American black bear (Oftedal & Gittleman, 1989 Ramsay & Dunbrack, 1996 Zhu et al., 2001). The giant panda neonate is particularly altricial (i.e....

Much of the progress is the result of personal relationships that developed during the course of the Survey, which, in turn, provided...

Common Medical Problems Of The Adult Giant Panda

There is a paucity of well-documented information about the common medical problems of giant pandas often what is known is presented in Chinese journals. From 1998 to 2000, the CBSG Biomedical Survey helped to improve substantially the body of reference knowledge on this species, as well as to survey for medical problems (see Chapter 4). The only other comprehensive reference on medical problems in the giant panda was produced by Qiu & Mainka (1993). Regardless, it is important to emphasise...

Ultrasoundguided Ai And Postbreeding Monitoring In The Female Giant Panda

At no time during the eight years that the giant pandas were together at the Berlin Zoo did natural breeding occur. Therefore, AI was developed, and from 1997 to 2003, six ultrasound-guided inseminations were conducted (see Table 17.1). Follicular development and ovulation were induced in the female with exogenous gonadotrophins for four of the six inseminations. Ovarian responses were relatively uniform, with one to three graafian follicles (> 6 mm in diameter) and more than ten smaller...

In the Figure 8.4....

Assisted Reproduction

Artificial insemination with fresh semen is a valuable management tool for the captive breeding of giant pandas due to the high incidence of sexual incompatibility. It is common practice in China to combine natural breeding and AI. Generally, the one available 'breeding' male is used to copulate with the female after which she is immediately inseminated with semen from one or more males in an attempt to ensure pregnancy and promote genetic diversity. Paternity analysis has revealed that siring...

In contrast, a detailed analysis of early survival rates over time found substantial improvements in cub survival to seven days of age Fig. 21.6 . From 1990 through 1997, cub survival decreased sharply, averaging less than 50 by 1997. Since 1998, however, survival has ranged from 73 to 90 , an improvement attributable to several factors. For instance, in 1998 and...
