“…A relationship was also noted between oxytocin concentration in the sow's body and the mobilization of body reserves; the greater the concentration, the greater the mobilization, which positively affects milk production and the growth rate of piglets (Valros et al, 2004). In our study, the body weight of piglets was only slightly higher (P≤0.05) in multiparous sows from group I compared to those from group II.…”

Sixty crossbred sows were investigated for the effect of the level of fat reserves in high pregnancy and pre-weaning changes in lipid reserves on reproductive performance of sows and rearing of piglets. At 104 days of pregnancy and at weaning, sows were analysed for body weight, P 2 and P 4 backfat thickness and M. Longissimus dorsi (MLD) thickness at P 4 M (Piglog 105). Sows were grouped according to mean backfat thickness (P 2 + P 4 )/2 at 104 days of pregnancy into primiparous (P 2 + P 4 )/2>18 mm (group I), primiparous (P 2 + P 4 )/2≤18 mm (group II), multiparous (P 2 + P 4 )/2>20 mm (group I) and multiparous (P 2 + P 4 )/2≤20 mm (group II). The body weight of sows from group I was higher than sows from group II at 104 days of pregnancy (P≤0.05) and at weaning (P≤0.01). As assumed in the experiment, fatness in high pregnant sows (points P 2 and P 4 ) was significantly higher in group I than in group II (P≤0.01), and the differences between the groups persisted when piglets were weaned (P≤0.01). At weaning, sows from group II had a significantly greater P 4 M thickness compared to sows from group I. The differences in backfat thickness in late-pregnant sows in groups I and II and in the loss of fat reserves during a 21-day lactation had no effect on reproduction results and rearing of piglets. Sows lost body weight to a small extent and fat reserves to a moderate degree; the changes were greater in primiparous than multiparous sows, regardless of the group (I or II). Streszczenie U 60 loch mieszańców określono wpływ poziomu rezerw tłuszczu w ciąży wysokiej i zmian zasobów lipidów do odsadzenia miotu, na wyniki rozrodu i odchowu prosiąt. W 104. dniu ciąży i przy odsadzeniu określono u loch masę ciała, grubość słoniny w punktach P 2 i P 4 oraz grubość M. longissimus dorsi (MLD) (pkt. P 4 M) (Piglog 105). Lochy podzielono na grupy w zależności od średniej grubości słoniny (P 2 + P 4 )/2 w 104. dniu ciąży; pierwiastki (P 2 + P 4 )/2>18 mm (grupa I), pierwiastki (P 2 + P 4 )/2≤18 mm (grupa II), wieloródki (P 2 + P 4 )/2>20 mm (grupa I) oraz wieloródki (P 2 + P 4 )/2≤20 mm (grupa II). Masa ciała loch z grupy I vs. II była większa w 104. dniu ciąży (P≤0,05) i przy odsadzeniu (P≤0,01). Otłuszczenie wysoko prośnych loch (pkt. P 2 i P 4 ) było zgodnie z założeniami eksperymentu istotnie większe w grupie I vs. II (P≤0,01); zróżnicowanie otłuszczenia między grupami utrzymało się przy odsadzeniu prosiąt (P≤0,01). Przy odsadzeniu stwierdzono u loch z grupy II vs. I istotnie większy wskaźnik P 4 M. Zróżnicowanie grubości słoniny u wysoko prośnych loch w grupach I i II i strat rezerw tłuszczu w 21. dniowej laktacji, nie miało wpływu na wyniki rozrodu i odchowu prosiąt. Lochy traciły w niewielkim zakresie masę ciała i na umiarkowanym poziomie zasoby tłuszczu; zmiany były większe u pierwiastek vs. wieloródek, niezależnie od przynależności do grup eksperymentalnych (I lub II).

“…In contrast, progesterone maintains pregnancy by promoting the secretion of intrauterine glands to sustenance the fertilised eggs, stimulates the expansion of the mammary glands, and induces maternal behaviour. Further, the decrease of progesterone and a subsequent rise in prolactin cause the common maternal behaviours seen in dogs, including nesting [45,50] (Figure 1).…”

Mammalian parental care, in most of the cases, is given by the female, who provides food, warmth, and protection. In domestic dogs, maternal behaviour shown by the dam mainly consists of contact, nursing, grooming/licking, play, punishment, thermoregulation, and motion. Peer-reviewed literature published between 1952 and 2018 was retrieved from CAB Abstracts, PubMed, ISI Web of Knowledge, Scopus and book chapters. Keywords for this search included the following terms: behaviour, bonding, altricial, precocial, offspring, maternal, whelping, nursing, domestic dogs, female dog, aggression, puppies, anogenital licking. In this review, we reported and discussed scientific information about maternal behaviour in domestic bitches, comparing altricial vs precocial species; the importance of the bonding, grooming/licking and nursing, and their impacts on puppies' behaviour; altered maternal behaviours such as aggression, cannibalism, rejection, and also the relation between hormones and maternal care behaviours. We concluded that the level of interactions between the dam and the puppies influences the physiological, cognitive and behavioural development of the litter, and the main hormones in the bitch for inducing maternal care behaviours are estradiol, oxytocin, prolactin and progesterone.

“…One could argue that for biological activity, only a slight release of OT might be sufficient. During milk ejection, for example, OT peaks are much lower than after introduction of a boar during estrus: 6–14 pg/ml (Kotwica and Okrasa 1989), 10–50 pg/ml (Valros et al. 2004), 10–30 pg/ml (Ellendorff and Parvizi 1982).…”

“…Oxytocin does not always peak after a suckling has been initiated: approximately 40 to 90% of sucklings are associated with a clear OT peak, depending on the definition (Rojkittikhun et al 1993). The magnitude of the peak varies between 6 and 30 pg/ml in different studies (Ellendorff and Parvizi 1982;Kotwica and Okrasa 1989;Valros et al 2004). There is no evidence in pigs on the release of OT caused by exogenous stimuli in other reproductive phases.…”

Nine multiparous cyclic sows with permanent jugular catheters were introduced to a boar at day 10 (n = 9) or 11 (n = 5) after ovulation to study the effect on oxytocin (OT) release. If it occurs, the release of OT might play a role in embryo migration which occurs around this time, by stimulating uterine contractions. Blood samples were taken before introduction of the boar and at 2-min intervals up to 10 min after boar introduction. On average, OT levels after boar introduction were not higher than before. In only three out of the 14 occasions of boar introduction, a rise in OT level was observed that was higher than two times the standard deviation above base level. However, even on these occasions OT levels were far below the range normally observed during other events where exogenous stimuli cause OT release, such as boar introduction during estrus and suckling during lactation. We conclude that boar contact around day 10 of the estrous cycle does not induce a biologically significant OT release in sows.
