Ovarian folliculogenesis in collared peccary, Pecari tajacu (Artiodactyla: Tayassuidae).
The sustainability and production of collared peccary (Pecari tajacu) has been studied in the last few years; however, further information on its reproduction is necessary for breeding systems success. Understanding folliculogenesis aspects will contribute to effective reproductive biotechniques, which are useful in the preservation and production of wildlife. The aim of this study was-to evalu...
متن کاملEvaluation of genetic variability in the collared peccary Pecari tajacu and the white-lipped peccary Tayassu pecari by microsatellite markers
In this study, the microsatellite technique was used to evaluate the genetic variability in populations of collared and white-lipped peccaries kept in captivity. Six primers developed for domestic pigs were used and amplified in both species. They revealed the presence of five polymorphic loci and one monomorphic locus. The polymorphic loci included 4 of the 16 alleles in collared peccaries, an...
متن کاملHistomorphometrical and proliferative aspects of placenta and uterus of the collared peccary (Tayassu tajacu).
The histomorphometric and proliferative characteristics of the collared peccary (Tayassu tajacu) placenta and uterus were analyzed. The material was examined by standard histological techniques and histochemistry (PAS, Perls and Alcian Blue pH 0.5 and 2.5%) and the cellular proliferation by AgNORs and flow cytometry. All the analyzed morphometric variables differed between pregnant and non-preg...
متن کاملEffect of Different Freezing Rates and Thawing Methods on the Quality of Frozen Boar Semen
A total of 30 ejaculates from three Hampshire crossbred boars were used to study the effect of freezing rates and thawing methods on quality of frozen boar semen. Semen was frozen using three freezing rates-30 0 c/min, 50 0 c/min and 70 0 c/min in a programmable biological semen freezer. The semen characteristics viz., sperm motility, live sperm, HOST reacted spermatozoa and intact acrosome wer...
متن کاملEvaluation of two different boar semen freezing protocols and their effects on semen quality after thawing
The aim of this study was to evaluate the quality of boar sperm using two different freezing techniques. The protocols were proposed by Westendorf and Paquignon. In both methods the seminal plasma is removed. In the protocol Paquignon the seminal plasma is removed at environmental temperature and the Westendorf protocol suggests that the plasma withdrawal should be made at 15oC. The sperm suspe...
