“…This is consistent with the difference in BW of PRI and MUL ewes from conception until lambing, indicating that PRI ewes invested proportionally more energy than MUL ewes in the development of their foetus rather than investing in maintaining their growth rate. Although pregnancy is a greater metabolic challenge for PRI than for MUL ewes 13 , it would appear that in these study conditions, PRI ewes prioritized the foetus at the cost of their own growth. The PRI ewes carried a greater foetal burden through gestation than MUL ewes in relation to the maternal BW, which is consistent with lower blood protein concentration in PRI ewes, a consequence of higher protein expenditure for foetal growth.…”

The aims were to compare ewe-lamb behaviours between primiparous (PRI) and multiparous (MUL) undernourished grazing ewes at birth and at 3 months of age, and to determine if mothers’ parity affects milk yield and composition, and lambs’ body weight (BW). Food availability restricted the nutritional requirements from day 30 to day 143 of gestation. The MUL ewes had greater BW than the PRI during gestation, and their lambs tended to vocalize less frequently until their first suckle. PRI ewes both displayed a lower frequency of acceptance behaviours and, a greater number of high-pitched bleats toward the alien lamb than toward that of their own, but MUL did not. PRI ewes produced less milk than the MUL ewes. The heart rate was greater in lambs reared by MUL ewes than by PRI. Although PRI ewes had a lower BW during gestation, this difference was stable throughout and did not affect the establishment of the ewe-lamb bond neither at birth nor at 3 months postpartum. At least under nutritionally restricted conditions during gestation, inexperienced mothers appeared to have had a shorter sensitivity period of maternal responsiveness than that of experienced mothers.

“…This is accentuated if the mother is moved from her birthplace or has suffered stress or disturbances of any kind despite the significant stimulus generated by the presence of her newborn [112]. For example, primiparous buffaloes are more likely to show inappropriate behavior in comparison with multiparous buffaloes [113][114][115][116]. Inexperienced buffalo cows could sometimes delay the calf s first suckling with aggressive or rejection behaviors, which can negatively influence the growth or survival of the calf [111].…”

In buffaloes and other mammalian farm species, the mother provides food and protection to the young, but she is also the main source of behavioral and social learning for the offspring. It is important that mother and young establish a bond based on a learning mechanism defined as “imprinting” early after parturition during the sensitive period, on which the welfare and survival of the offspring will depend. This review aims to summarize and discuss current knowledge regarding the imprinting process, the neurobiological pathways that are triggered during this sensitive period, and the development of the cow–calf bond. Touch, hearing, vision, and smell seem to be the predominant senses involved during imprinting in buffaloes and other mammalian farm species. In buffalo, bonding is very particular due to the expression of specific behaviors, such as allo-suckling and communal rearing. In general, imprinting and the subsequent bond may be affected by the lack of experience of the mothers or dystocic parturitions, which occur most frequently with male calves and in primiparous dams. The main problems in the development of this process include lack of seeking a protected and isolated place to give birth; moving from the birth-site after parturition; insufficient postpartum care; aversion or aggressiveness towards the newborn, or abandonment of the newborn. The process can develop differently according to the species. However, the correct development of the cow–calf relationship represents, regardless of the species, a key factor for their fitness.

“…Lambs born from PRI mothers are lighter and thus, slower to stand up and suckle for the first time than lambs born from MUL mothers 9 . Even one day after birth, lambs born from PRI ewes have impaired ability to distinguish their mother from that of an alien one 13 , which is related with a greater mortality rate of their lambs 14 . However, to the best of our knowledge, there is paucity on information on the evolution of the ewe-lamb bond throughout lactation according to the parity.…”

The aims were to compare ewe-lamb behaviours between primiparous (PRI) and multiparous (MUL) undernourished grazing ewes at birth and at 3 months of age, and to determine if mothers’ parity affects milk yield and composition, and lambs’ body weight (BW). Food availability restricted the nutritional requirements from day 30 to day 143 of gestation. The PRI ewes had lower BW than MUL during gestation, and their lambs tended to vocalize less times until their first suckle. PRI ewes displayed a lower frequency of acceptance behaviours toward the alien lamb than toward their own lamb, but MUL did not. Whilst PRI ewes emitted a greater number of high-pitched bleats toward the alien lambs than toward their own lamb, MUL did not. PRI ewes produced less milk than the MUL ewes. The heart rate was greater in lambs reared by MUL ewes than by PRI. Although PRI ewes had a lower BW throughout the gestation, this difference was stable and did not affect the establishment of the ewe-lamb bond at birth or at 3 months postpartum. At least under nutritionally restricted conditions during gestation, inexperienced mothers appeared to have a shorter sensitivity period of maternal responsiveness than experienced mothers.
