“…These data imply that the secretory conditions of the uterus at the time of the upper vaginal AI have a significant effect on the duration of the fertile egg production. This finding is in agreement with other studies reporting a longer period of fertilized egg production by hens when the AI is performed in the afternoon or evening compared to in the morning (Johnston and Parker, 1970;Brillard et al, 1987).…”

Effects of Fluid Secreted from the Uterus on Duration of Fertile Egg Production in Hens, and Survivability and Penetrability of Fowl Sperm <i>in vitro</i>

In this study, whether the secretion of the uterine fluid (UF) exerts a role in the prolongation of functional lifespan of the sperm in the hen oviduct was evaluated. The sperm were subjected to upper vaginal artificial insemination (AI) in the vicinity of the utero-vaginal junction (UVJ) under conditions of either non-secretion, plumping fluid (PF) secretion, or calcifying fluid (CF) secretion of the uterus of hens. Aliquots of the sperm were also subjected to in vitro storage at 41℃ for 0, 2, 4, and 6 h in Lake's solution (LS), PF and CF. Following AI, the exposure of the sperm to either PF or CF secretion resulted in a remarkably a longer duration of the fertile egg production compared to when the AI was performed during the non-secretory phase of the uterus (P＜0.05). Similarly, the in vitro exposure of the sperm to PF and CF during storage resulted in increased survivability and penetrability of the sperm compared with storage in LS (P＜0.05). In particular, distinct functional differences (P＜0.05) were observed between the sperm stored in vivo and in vitro under PF and CF conditions. The sperm inseminated in the presence of PF secretion exhibited a longer period of fertile egg production, and the sperm stored in PF in vitro exhibited a higher capacity for survival and penetration into the inner perivitelline layer (IPL) than those inseminated in the presence of CF secretion or were stored in vitro in CF, respectively, indicating that exposure of the sperm to the UF might influence sperm function. In conclusion, the in vivo and in vitro findings suggest that the secretion of UF in the oviduct of hens may prolong sperm survival and maintain the fertility potential of the fowl sperm.

“…Importantly, mating dynamics showed distinct daily patterns driven by the fact that the probability that an insemination results in fertilization is highest at least 4 h following oviposition and thus typically in the evening (Moore and Byerly 1942;Parker 1945;Johnston and Parker 1970;Christensen and Johnston 1977). In light of this, it seems puzzling that female fowl should solicit in the morning.…”

“…Oviposition occurs in the first half of the day (Etches 1996) and peaks in the middle of the day (Christensen and Johnston 1977;Johnson 2000;Pizzari and Birkhead 2001). Inseminations occurring a few hours before and after oviposition have limited fertilizing efficiency (Moore and Byerly 1942;Parker 1945;Johnston and Parker 1970;Christensen and Johnston 1977) relative to inseminations in the evening (natural matings: Gracewski and Scott 1943;Parker 1945;artificial inseminations: Moore and Byerly 1942;Parker 1945;Christensen and Johnston 1977). Therefore, the evening corresponds to an optimal copulation time because by copulating at this time, a female can minimize the number of copulations required to fertilize her eggs while maximizing fertilization success.…”

Sex in the Morning or in the Evening? Females Adjust Daily Mating Patterns to the Intensity of Sexual Harassment

Selection on males to mate at a higher rate than females often results in male harassment of females and counteracting female responses. When the reproductive value of copulation changes over time, these mating strategies are expected to be time dependent. Here, we demonstrate that variation in the intensity of male harassment leads to drastic changes in female daily mating patterns. In feral populations of fowl Gallus gallus domesticus, male harassment is intense, particularly in the evening when inseminations are most likely to result in fertilization. We experimentally manipulated the intensity of male harassment through similar-sized groups of different sex ratios. Male mating propensity was always higher than females', particularly in male-biased groups and in the evening, when males were closer to and more likely to approach females. Females counteracted male harassment by escalating resistance to mating and-cruciallyby shifting their daily mating pattern: in strongly female-biased groups with relaxed sexual harassment, females solicited sex in the evening, while in male-biased groups, they solicited sex in the morning, thus avoiding harassment in the evening. Together, these results indicate that intersexual conflict may occur not only over mating rates but also over when in the day to copulate.

Increased Embryonic Loss in Chickens From 0.05% Dietary Caffeine

White Leghorn pullets were fed standard laying rations supplemented with 0.0%, 0.05%, and 0.1% levels of dietary caffeine. There was no statistical difference in fertility among the three groups. Embryonic loss in eggs from pullets fed 0.05% caffeine was between values previously reported for 0.0% and 0.1% dietary caffeine. This suggests that embryonic mortality increases as levels of caffeine are increased in the diet up to 0.1%.
