Abstract
The efficacy of Truong Xuan Cao Bang (TXCB), a Vietnamese herbal medicine prescription, on the quality of semen, serum testosterone (TES), and malondialdehyde (MDA) concentrations in rabbits whose reproductive ability were impaired by fluconazole was investigated. Mature male rabbits were randomly assigned into control (G1), fluconazole (G2), fluconazole and 180 mg/kg/day (G3), and 360 mg/kg/day TXCB (G4) groups. The reaction time (RT), ejaculate volume (EV), sperm concentration (SC), total sperm output (TSO), total sperm motility (TSM), progressive sperm motility (PSM), nonprogressive sperm motility (NPSM), sperm immobility (SIM), dead sperm (DS), and abnormal sperm (AS) levels were determined after TXCB administration. After 60 days, G3 showed a significant increase in serum TES and a significant decrease in the concentrations of serum MDA (SMDA) and seminal plasma MDA (SPMDA) compared with G1, in addition to increase in EV, SC, TSO, TSM, PSM, and serum TES, and decrease in RT, SIM, DS, AS, SMDA, and SPMDA compared with G2. G4 showed a steep rise in EV, SC, and serum TES and a downturn in DS, SMDA, and SPMDA compared with G1, and, compared with G2, a significant increase in EV, SC, TSO, TSM, PSM, and serum TES and a significant decrease in RT, SIM, DS, AS, SMDA, and SPMDA. Taken together, TXCB rehabilitates and simultaneously enhances spermatogenesis in rabbits whose reproductive ability was impaired by fluconazole.

Abstract
The use of animal models remains critical in preclinical and translational research. The reliability of the animal models and aspects of their validity is likely key to effective translation of findings to medicine. However, despite considerable uniformity in animal models brought about by control of genetics, there remain a number of social as well as innate and acquired behavioral characteristics of laboratory animals that may impact on research outcomes. These include the effects of strain and genetics, age and development, sex, personality and affective states, and social factors largely brought about by housing and husbandry. In addition, aspects of the testing environment may also influence research findings. A number of considerations resulting from the animals' innate and acquired behavioral characteristics as well as their social structures are described. Suggestions for minimizing the impact of these factors on research are provided.

Abstract
Biostimulation is a non-hormonal and practical technique that has not yet been widely utilised when applied immediately before insemination to improve reproductive efficiency in livestock species. This study was conducted to determine the influence of short-term male biostimulation on behavioural and reproductive performance of inseminated rabbit does. A total of 142 female New Zealand White rabbits were randomly assigned to 3 groups. Females were either exposed to male odour (Odour group) or an adult aproned male (Male group), while the remaining does that were neither exposed to the male odour nor the adult male are considered the control group. All females were inseminated after the 2 h exposure session. Conception rates were determined by abdominal palpation 12 d after insemination. The results showed that conception rate of the male odour group (79.59%) was greater than that of male presence group (76.09%) and that of the control group (68.09%). Moreover, biostimulated does showed significant behavioural activities during the 2 h exposure session compared to the control group. Although no significant differences were recognised, litter size at birth and at weaning was slightly increased in biostimulated compared to control females. Nor were there any significant difference in serum oestradiol concentrations between treated groups. Conclusively, short-term 2 h biostimulation of rabbit does resulted in the appearance of various behavioural responses followed by differences in conception rates between groups after routine artificial insemination.

Abstract
Fecal corticosterone concentration (FCC) was measured in 14 buck rabbits individually housed in standard-dimension cages (SC) or in bigger cages (BC; with a volume more than double that of SC and equipped with a plastic foot mat) during 4 consecutive reproductive cycles. Cage type and reproductive phase (estrous synchronization of doe rabbits, artificial insemination, partum, preweaning, and postweaning) were not statistically significant but tendentially affected FCCs (.05 < p < .10). Buck rabbits housed in SC showed higher FCCs than those housed in BC (27.42 pg g(- 1) dried feces and 25.57 pg g(- 1), respectively; SEM = 2.952). The highest FCC values were detected at artificial insemination (BC, 27.91 pg g(- 1); SC, 30.45 pg g(- 1); SEM = 3.520), highlighting that the phase of semen collection could be one of the most critical moments for buck rabbits, although further investigations are needed. These preliminary results suggest that measurement of FCC could be used as an indicator of chronic stress in buck rabbits.

Sexual behavior and seminal characteristics of fertile mature New Zealand White male rabbits of different body weights. Anim Reprod Sci 2014; 152:90-8.

Abstract
Body weight in different mammalian species influences reproductive potential. The aim of the present study was to determine the relationship of body weight at the time of semen collection with libido, seminal characteristics and number of semen doses for artificial insemination (AI) in New Zealand White mature fertile male rabbits. Data came from 728 semen collections of 14 rabbits, 15-months of age that were sexually experienced with proven semen quality and fertility. Semen collection was performed twice a week with two ejaculates at each collection time and lasted 14 weeks. A second ejaculation was collected at 1-2h after the first. Data from each male from first and second ejaculates from 1 day of semen collection throughout the trial were averaged (n=324) and partial correlation coefficients and regression equations were estimated to describe the relationship of male body weight to ejaculation reaction time and 12 semen and sperm characteristics. As body weight increased there was a linear (P<0.05) increase in reaction time, abnormal sperm with an intact membrane and abnormal sperm with a damaged membrane and a linear (P<0.05) decrease in semen volume, sperm concentration per ejaculate, normal sperm with an intact membrane, number of normal motile sperm with an intact membrane and suitable semen doses for AI. Body weight of the mature male rabbit at semen collection had some influence on libido, semen and sperm characteristics, with a general trend toward a lesser reproduction potential as body weight increases.

Behavioural response of sexually naïve and experienced male rats to the smell of 6-methyl-5-hepten-2-one and female rat faeces. Physiol Behav 2013; 120:150-5.

Abstract
Sexually experienced male rats display penile erections when exposed to faeces from mammalian females in oestrus (Rampin et al., Behav Brain Res, 172:169, 2006), suggesting that specific odours indicate female receptiveness across species. However, it is unknown to what extent the sexual response observed results from an odorous conditioning acquired during sexual experience. We tested the behavioural response of male Brown Norway rats both when sexually naïve and experienced to four odours, including oestrous rat faeces and 6-methyl-5-hepten-2-one (methylheptenone; a molecule found in higher concentrations during oestrus in female rats, foxes and horses). Odour had a significant effect on the sexual response of the naïve rats, with oestrus faeces provoking significantly more erections than herb odour, and with methylheptenone and di-oestrus faeces being intermediate. This indicates that sexually naïve male rats have an unconditioned ability to detect oestrous mediated via odour. After gaining sexual experience, the response to methylheptenone, di- and oestrus faeces was significantly higher than that observed with herb odour. These results strongly suggest that methylheptenone is part of the odorous bouquet of oestrus and contributes to the olfactory determination of female receptiveness.
