Ciência Animal Brasileira, 2010 In swine, multiple artificial inseminations (AI) are commonly performed per estrus due to the long estrus duration. This observational study aimed to evaluate the association among the number of AI conducted per estrus, the estrus duration and the ...

Effect of constant light on parturition and postpartum reproduction in the rat [PDF]
, 1995 Light-dark (LD) cyclicity contributes to a number of reproductive events in the rat, including estrus cyclicity, and the timing of parturition and postpartum estrus.

Animal Models and Experimental Medicine, EarlyView.Irrigation of periodontal pockets with human periopathogens, in combination with a 14‐day ligature‐induced periodontitis protocol, significantly enhances alveolar bone loss and sustains bacterial colonization for up to 28 days following ligature removal, thereby more closely replicating the chronic nature of human periodontitis compared to the ligature

Jurnal Veteriner, 2017 The timing of artificial insemination relies largely on behavioral observation of estrus. The problemfaced is that not all cattle shows signs of estrus significantly, which affect the accuracy of insemination,and therefore,the success rate of Artificial ...

Generating golden Syrian hamsters with conditional alleles via zygote microinjection of CRISPR/Cas9
Animal Models and Experimental Medicine, EarlyView.We established the first conditional knockout (cKO) model in the golden Syrian hamster by CRISPR/Cas9‐mediated genome editing. Cas9 protein, two sgRNAs, and a donor plasmid carrying loxP‐flanked exon 2 of the ApoF gene were microinjected into one‐cell embryos. The floxed allele was efficiently generated (up to 27%) and transmitted through the germline.
