Introduction
1. The urgency of the thesis
The Common Palm Civet (Paradoxurus hermaphroditus
Pallas, 1777) belongs to the Viverridae family, carnivora (Carnivora).
This animal is widely distributed in Central, South and Southeast Asia.
In Vietnam, the civets are widely distributed across the country [7].
Hunting and use of civet taps for different purposes such as
meat, leather, fur, aromatherapy, used in the production of weasel
coffee along with their declining habitat are depleting this species in
nature [2, 8]. Preserving and storing genetic resources is one of the
urgent, regular and long-term solutions [9]. In order to sustainably
preserve livestock gene sources, the exploitation and development of
genetic resources is an effective solution [10]. Therefore, in Vietnam,
successfully built many breeding civet farms. The civet farming in
addition to bringing high economic efficiency to the farmers also helps
to reduce hunting and contribute to preserving biodiversity [11].
In breeding management and improvement of the civet
process, studying their biological characteristics and increasing their
reproductive performance are very important. Therefore, the topic
"Biological characteristics and effects of gonadotropin on
reproductive ability of common palm civets (Paradoxurus
hermaphroditus Pallas, 1777) in captivity" is carried out.
2. The aims of the thesis
- Identify biological characteristics, some indicators of
physiological and biochemical blood and urine of civets in captivity.
2
- Determine the change in sex hormones of female civets and
evaluate the effect of sexual stimulation on the fertility of civets in
captivity in order to preserve herd in the direction of quantity
development.
3. The main contents of the thesis
- Study on biological characteristics (appearance, behavior,
growth, reproduction) of the civets in captivity
- Studying on physiological and biochemical parameters of the
civets in captivity.
- Study on the change of sex hormones of the female civets in
captivity.
- Study on the effect of gonadotropin (PMSG, HCG) on the
reproduction of female civets.
CHAPTER 1. LITERATURE OVERVIEW
1.1. Overview of the common palm civets
This section presents an overview of the characteristics of species,
appearance, behavior, reproduction, distribution of species in nature and
current situation of breeding civets.
1.2. Overview of research on the common palm civets
This section presents research on the civets in the world and in
Vietnam. The studies mainly focused on the behavior, physiological and
biochemical characteristics of this species in nature, in terms of genetic
diversity and phylogeny.
1.3. Overview of PMSG and HCG
An overview of structure, functions, applications and studying of
the use of PMSG and HCG in livestock.
1.4. Overview of estrogen and progesterone
3
An overview of the structure and function of estrogen and
progesterone; method of extracting and identifying them through faeces.
