“…In addition, artificial insemination is routinely performed in rabbit farming and rabbit semen is commercially available. The pregnancy rate of does artificially inseminated either with control or tagged semen in the present study was similar to that described in other studies (Khalifa, 1994;Rebollar et al, 2012). No differences in gestation length, in the number of kittens at birth per female or in the number of live kittens per litter were observed.…”

The increasing number of patients undergoing assisted reproductive technology (ART) treatments and of cycles performed in fertility centres has led to some traceability errors. Although the incidence of mismatching errors is extremely low, any error is unacceptable, therefore different strategies have been developed to further minimize these errors, such as manual double-witnessing or electronic witnessing systems. More recently, our group developed a direct tagging method consisting of attaching microbarcodes directly to the zona pellucida of human oocytes/embryos. Here, this method is taken a step further by using these microbarcodes to tag human semen samples, demonstrating that the barcodes are not toxic and do not interfere in the selection of motile spermatozoa nor in the cryopreservation of the sperm samples. In addition, when this tagging system was applied to an animal model (rabbit), pregnancy rate and kitten viability were not affected.

“…Nowadays, a great attention has been focused to apply artificial insemination (AI) in most Rabbitries where intensive rabbit raising is practiced (Seleem and Rowida, 2007). Although AI maximizes the economical profit of rabbit industry by reducing the bucks and cages numbers (Khalifa et al, 2002), it is still practiced on a very limited scale in Egyptian Rabbitries. One of the main constraints is that the disability of buck semen to be stored for a long period without the loss of its fertilization ability (Seleem et al, 2008).…”

This study was designed to evaluate mature New-Zealand White (NZW) rabbit reproductivety as affected by different levels of Ganoderma ® in diets. Animals were divided into three comparable experimental groups (16 sexual mature bucks and 52 mono-parous does in each). The first group was fed a commercial diet and kept untreated (control group), while the 2 nd and 3 rd groups (treated groups) were fed the same diets but supplemented with 200 and 400 g Ganoderma ® / ton diet, respectively. Results obtained showed that, feeding diet supplemented with different levels of Ganoderma ® improved significantly (P≤0.05) libido and physical semen quality of bucks, while values of semen enzymatic activity were decreased significantly (P≤0.05) and sperm penetration into estrus cow cervical mucus significantly (P≤0.05) increased due to treatments. Diluted semen ejaculated by NZW rabbit bucks fed diet supplemented with different levels of Ganoderma ® or/ and added with 1 ml Ganoderma ® aquas extract/100 ml diluted semen recorded significant (P≤0.05) increase in viability, quality and storagability, during the storage at refrigeration and incubation temperatures. Diluted semen ejaculated by rabbit bucks fed diet contained Ganoderma ® and supplemented with Ganoderma ® showed quality significantly (P≤0.05) better than that ejaculated by treated bucks and free Ganoderma ® , followed by diluted semen of untreated bucks and free Ganoderma ® , respectively. Physical semen quality and sperm penetration into estrus cow cervical mucus values significantly (P≤0.05) decreased and increased, respectively, with progressive of conservation time. Fertility traits of does represented in (rates of each of abortion, conception and kindling and values of each of litter size and weight at birth and at weaning, as well as, bunny weight at birth and at weaning were significantly (P≤0.05) better by adding different levels of Ganoderma ® in diets. The improvement in parameters indicated fertilizing ability of bucks and fertility traits of does were arranged (P≤0.05) in descending order as recorded by 400, 200 then zero g Ganoderma ® / ton diet, respectively. While 400 g Ganoderma ® /ton recorded insignificantly improvements in most studied parameters than 200 g Ganoderma ® /ton.In conclusion, NZW rabbit bucks or does feeding diets supplemented with different levels of Ganoderma ® recorded significant (P≤0.05) improvement in all parameters studied, during mature period. This means that 200 g Ganoderma ® / ton diet is recommended for mature rabbits.

“…This was in agreement with the findings of Tawfeek and El-Gaafary [18] who reported that natural mating yielded significant litter size at birth and at weaning compared to artificial insemination (AI) using HCG treatment (p<0.05). Oke and Iheanacho [19] reported that natural mating in rabbits produced a significantly higher conception rate of 79.9% compared to 56.4% in rabbits undergoing AI, in contrast with the findings of Khalifa [20] who reported an insignificantly higher conception rate in does that 108 Obasi KK et al mated naturally. Sexual receptivity at insemination has been attributed to increase the number of live foetuses in rabbits after AI, associating it to a better fertility due to high numbers of pre-ovulatory follicles found in the ovaries and higher plasma oestrogen concentrations.…”

Objectives: Artificial insemination (AI) is the introduction of spermatozoa into a female's uterus or cervix for the purpose of achieving pregnancy. It is a fertility treatment for humans, in animal breeding and embryo-fetal developmental studies. This study investigated the embryo-fetal development in the rabbit via artificial insemination by evaluating the litter size, reproductive data and external morphological abnormalities after insemination. Methods:Ten adult female and three male rabbits weighing 1.8 kg and 2 kg, respectively were used. Group A served as the natural mating, while Group B served as the AI group, and the males served as semen donors. On day 28 of gestation, does were subjected to caesarean section. The ovaries and uteri were removed and examined for the number of corpora lutea and the status of all implantation. Results:Results showed a significant increase in fetal weight, total fetal number, total resorption sites, number of implantation and total number of live foetuses (p<0.05), while there was no significant increase in parameters like average fetal weight, placenta weight, uterine gravid weight, number of corpora lutea and sex ratio in Group B compared to Group A (p>0.05). A conception rate of 100% was observed in Group A compared to Group B with 80% conception rate. External examination carried out on the foetuses revealed no external abnormalities in both groups. Conclusion:The results of this study show the clear advantages in the use of rabbits for AI in terms of embryo-fetal developmental studies.
