“…Interestingly, not so much the suckling act itself is important for inducing the secretion of prolactin, but only the mere stimulation of the abdominal wall. This was proven by González-Mariscal and Gallegos (41), who found high concentrations of prolactin in females after mastectomy, "nursing" offspring.…”

“…Although prolactin is not the most important hormone in the nest building behavior, its secretion at the end of the pregnancy is extremely important for lactation, as in most mammals and behavior called "crouch over the pups" in the first days after parturition (43). What is very interesting, in contrast to most species which display a continuous interaction with their young throughout lactation, in rabbits the mother-young interaction is restricted to a minimum: a 3 ± 5 min bout of nursing each day, but it seems enough for maintaining lactation for the next 30 days (41).…”

Hormonal regulation of rabbit pregnancy and related behavioral changes has been extensively studied for the last century. The present review aimed to summarize and clarify certain aspects of this period. The article consists of six chapters describing in sequence: maternal reproductive track, gestation, maternal cyclical phenomena, pregnancy and lactation, hormonal profile in pseudo-pregnancy, behavioral changes.

“…However, the time point of grouping did not affect aggression in does in two experimental studies (Braconnier et al, 2020;Bill et al, 2020). However, as weaning naturally occurs around 20-28 d postpartum, depending on the current pregnancy state of the does (González-Mariscal and Gallegos, 2014;Hudson et al, 1996Hudson et al, , 2000, the later time points of grouping might still have been too early to reduce aggression. Nevertheless, progressing gestation, similar to early lactation, could cause an increase in aggression compared to mid-or early gestation, as has been described in mice (Mann and Svare, 1982).…”

The neuroendocrine regulation of rabbit maternal behaviour has been explored in detail. However, little is yet known about the hormonal regulation of aggression in concurrently pregnant-lactating does, a reproductive condition that prevails during group housing of rabbits on farms. Therefore, in this study we determined the relation between a) the levels of progesterone, testosterone, and oestradiol during lactation; b) the anogenital distance at artificial insemination; and c) the timing of grouping with the intensity of agonistic behaviour, published previously. We performed four consecutive trials, where three groups of eight does each were artificially inseminated on day 10 postpartum (pp) and grouped on either day 12, 18 or 22 pp. Using Dipetalogaster maxima, a reduviid blood-sucking bug, we collected blood samples during the pregnant-lactating phase (days 13, 15, 17, 19, 21, 23 pp) on one or two randomly chosen does per treatment group. Testosterone levels varied little across the pregnant-lactating phase, agreeing with results from pregnant-only rabbits, while progesterone levels increased from day 3 (=13 dpp) to day 7 (=17 dpp) and remained unchanged until day 13 (=23 dpp) of pregnancy. All oestradiol concentrations fell below the limit of detection. Overall, all concentrations were slightly lower in comparison to rabbit studies with pregnantonly does. The agonistic behaviour was not related to the respective hormonal concentrations at grouping. In conclusion, the time point of grouping does after artificial insemination (AI) in the semi-group housing system only had a weak influence on aggression and the hormonal profile did not indicate an optimum time for grouping.

“…Ducks laying floor eggs sit more, walk less, fight less, avoid entering into the next box, and exhibit no nest-seeking behavior ( Barrett et al, 2019 ), which is similar in mammals and rodents ( Deacon, 2006 ; Kinsley and Amory-Meyer, 2011 ; Jirkof, 2014 ). For example, rabbits with poor motherhood do not make a nest before delivery or give birth in the nest ( González-Mariscal and Gallegos, 2014 ). With the emergence of modern molecular genetics and more detailed analysis of maternal behaviors, the role of changes in the endocrine hormone levels [i.e., progesterone ( P4 ), prolactin ( PRL ), and dopamine ( DA )] and specific gene expressions [e.g., progesterone receptor ( PGR ), oxytocin receptor ( OXTR ), and dopamine receptor ( DRD )] in the participation and regulation of maternal behaviors has received more attention ( Bridges, 2015 ; Bridges, 2020 ).…”
