Size Inheritance in Guinea-Pig Crosses

Karyotype of Hairless Guinea pig

Chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. Chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and G banding techniques. The chromosomes diploid number was 2n= 64 and polymorphism of three type chro...

Effect of Anodal and Cathodal Microamperage Electrical Stimulation on Injury Potential and Size of Acute Wound in Guinea Pig

Introduction: It is believed that injury potential has a regulatory role in wound healing process and the application of exogenous electrical stimulation may serve to mimic the natural endogenous bioelectric current so that can improve the wound healing. Up to now, this hypothesis has not been researched in surgically acute wounds. Materials and Methods: Thirty nine male guinea pigs were random...

Heterosis for litter size traits in native by two exotic inbred pig crosses

Inbred strains generated from native and exotic pigs were compared with their F1and f2 backcross populations for a range of litter size performance traits. Animals were intensively reared and at 81⁄2 months of age, the inbred genotypes from each strain were reciprocally mated to each other to generate F1 crossbred genotypes; while gilts from each crossbred group were backcrossed to their male p...
