- Abstract:
- ... A total of 548 Manchega ewes were used to compare progestagen impregnated intravaginal sponges (12 days) plus eCG with melatonin implant (100 days) treatments, as possible stimulants of reproductive performance during the seasonal anoestrus and the lactation period. The use of both methods of oestrous manipulation induced a significant improvement in conception rate (78% for progestagen and eCG; 7 ...

- Abstract:
- ... Allelic variations in the second exon of caprine leukocyte antigen-DRB3 gene (CLA-DRB3*02) were investigated. A total of 459 animals from 12 Chinese indigenous goat populations were genotyped. Six alleles and 18 restriction digestion profiles were distinguished by digestion of PCR amplification product of CLA-DRB3*02 with HaeIII. The results suggested that there were significant difference (P < 0. ...

- Abstract:
- ... Genetic variation at 23 microsatellite loci, population structure, and genetic bottleneck hypothesis were examined for Jamunapari goat population found in Etawah, Uttar Pradesh, India. Estimates of genetic variability such as effective number of alleles and gene diversities revealed substantial genetic variation frequently displayed by microsatellite markers. Number of alleles observed across the ...

- Abstract:
- ... The αS1-casein (CSN1S1) locus in the goat is characterized by a polymorphism, the main feature of which is to be qualitative as well as quantitative. This highly polymorphic protein is encoded by at least 17 alleles including null alleles. The null allele CSN1S1⁰¹ is very interesting for further study, because of the high effect of this allele on milk properties, or for its utilization in special ...

A new commercially available ELISA (ELISA-Chlamydophila abortus, ELISA-C. abortus) for detecting antibodies against C. abortus was evaluated using field sheep and goat serum samples. This ELISA is based on a recombinant antigen that expresses part of a protein from 80 to 90 kDa family that is specific to C. abortus. Ser ...
