Vliv sourozenecké kompetice během přítomnosti u struku na mateřské chování u prasete domácího
Leszkowová, Iva ; Illmannová, Gudrun (advisor) ; Špinka, Marek (referee)
This diploma thesis deal with the neonatal sibling competition during nursing within first day after farrowing, focusing on maternal reaction on neonatal sibling competition during nursing. We predicted that the sow will terminate nursing by a changing posture or by a non- nutritive nursing (i.e. nursing without milk ejection) with increasing number of fights and screams. A total of 19 healthy sows and their litters were directly observed and video recorded during first day after farrowing for 6 h. The behaviour of piglets (fighting, screaming, presence at the udder) in the pre massage and the post massage was scored every 15 seconds. Piglets which missed milk ejection, posture changing of the sow and whether the nursing involve milk ejection were noted. A sum of fighting and screaming piglets in the pre massage and the post massage was calculated. A higher sum of fighting and screaming piglets correlated with a higher proportion of non-nutritive nursing (P<0.001) as well as with a higher proportion of sow posture changing in the pre massage (P<0.01). However, a higher sum of fighting and screaming piglets did not increase the probability of sow posture changing in the post massage. The results show a positive correlation between the litter size and the sum of fighting and screaming piglets in the...

Individual differences in maternal behavior (maternal style) of mammals
Leszkowová, Iva ; Špinka, Marek (advisor) ; Polák, Jakub (referee)
The expression "maternal style" in the wider sense serves to describe the interspecies interindividual and intraindividual, variability in the maternal care. In the narrow sense it is used only to designate permanent variability in the maternal behaviour among different mothers of the same species. The concept of the maternal style is based on a well-documented fact, that individual parts of maternal behaviour correlate with one another and this mutual bond enables to describe the varied repertoire of the mothers' behaviour by a few dimensions, such as e.g. protectiveness, restrictive, rejection and laissez-faire. Maternal style of primates was described in a wide range (e.g. Berman, 1990; Fairbanks, 1996). Up to today the existence of maternal style has been confirmed also with some rodents (guinea-pig: Albers, 1999; mouse: Benus a Rondigs, 1996), domestic animals (pig: e.g. Špinka et al., 2000; sheep: Dwyer a Lawrence, 2010; goat: O'Brien, 1984) and predators (dog: Wilsson, 1984). KEYWORDS : Maternal style, Maternal behavior, Individual differences, Parent-offspring conflict, Protectiveness, Rejection
