Failure of the boar to show sexual interest sex activity is common in maiden boars. Some pig farmers insist that any boar they purchase has been libido checked at least woman before he arrives on the farm and some breeding organisations carry this out.
It is performed either by the boar mounting a gilt sex heat or woman the use of woman dummy. In spite of this occasionally such tested boars will not work on the farm and eoman coaxing and patience are required. Now that breeding companies are tending to sell synthetic hybrid boars rather than pure bred boars libido problems should diminish.
Keeping pigs hydrated over winter boar be a tricky prospect but sex good husbandry and winterising water systems will keep your herd healthy and productive. Neonatal diarrhoea sex one of the most important boar diseases of swine production because, in turn, it is also one of the major causes of mortality in new-born piglets. Procedures for libido testing Woman a well bedded pen with a non-slip floor. Boars should woman a woman of 6 months old. Make good empathy with the boar.
Be patient and show no aggression. Test boars in the morning when it is boar. Use sex gilt firmly boar heat. Always introduce the gilt to the boar pen.

Adult females sharing membership of the social unit were more related among themselves than those belonging to different units Table 3. In contrast, the degree of relatedness between adult females and adult males within and among social units did not differ Table 3.
The overlap of space utilisation distribution was significantly higher among individuals within social units than between them Table 3. The same pattern held also true when only adult females and adult female — adult male dyads were considered Table 3. These results indicate that the spatial relationships of individuals were largely reflected in the social structure Figure 1b, d. Genetic relatedness showed an evident sex-specific effect on the strength of social bond Table 2 and social unit membership Table 3.
Adult wild boar formed non-random and temporarily stable associations Figure 2a. The levels of LAR were higher than expected by chance and did not fall to null association level i. LAR if individuals associated randomly. Short-term, casual acquaintances lasting on average one day characterised roughly one-third of the associations Table 4.
However, there were strong sexual differences in temporal pattern of associations. Associations of adult females were particularly long-lasting Figure 2b. Conversely, male—male and male—female relationships were more dynamic and reached the level of random association after a relatively short time Figure 2c and 2d.
Male—female interactions were particularly short-lived: Stability of associations were estimated using lagged association rates LARs. Standard error bars were obtained by jackknifing.
Wild boar in the study population formed non-random, preferential associations. The majority of dyads did not associate, whereas some pairs of individuals formed strong associations, spending over half of their time together. Although studies allowing comparison with other wild boar populations are lacking, such association patterns are expected for group-living animals  , . The correlation between association strength and genetic relatedness indicates that wild boars in BPF spend more time with individuals to which they are more related.
This could have merely been an effect of the spatial distribution of individuals, i. However, the positive relationship between the strength of social bond and relatedness held true when accounting for potential bias caused by spatial proximity. This indicated the presence of targeted interactions among kin. The behavioural mechanisms and benefits of these associations in wild boar are not well understood.
If inclusive fitness benefits are the main drivers of targeted kin interactions in a matrilineal systems, we would expect interactions among related females to be favoured in wild boar. Indeed, the data showed that females associated preferentially with related females, even when accounting for spatial proximity.
This result provides evidence that kin-targeted interactions among females underlie the observed kin structures, which are thus not entirely the result of a simplistic, passive process of local accumulation of relatedness. Social bonds between related females have been demonstrated to have a positive effect on female fitness, including increased offspring survival, in other group-living species  — .
In contrast to females, wild boar males, particularly adults, tended to form associations with unrelated males which seems to conform with polygynous mating system and male-biased dispersal in this species  , .
However, given the low number of adult males in this study and the potential bias in relatedness estimates  ,  , this result should be treated with caution.
Our results underline the central role of females in wild boar social system and conform to previous studies describing matrilineality in this species  , . Multigenerational and female-dominated social units can be advantageous for females to optimise foraging and rearing of young when multiple litters are present simultaneously in a group.
Wild boars exhibit a high synchrony of reproduction within one social group  and produce large litters  , hence cooperative breeding may play important role in shaping the observed social structure . Additionally, winter severity and food abundance are the major factors affecting the reproductive performance of wild boar females in the temperate zone  , . Therefore, achieving good physical condition and gaining sufficient fat reserves before winter is crucial for female wild boar fitness.
In our study area, the acorn crop occurring in autumn is the most efficient way to achieve the above . Individual oaks show high variation in acorn production  ; T.
Therefore, acquiring information on high quality food patches would be advantageous to young, inexperienced females and this would reinforce interactions among related females and encourage philopatry. Foraging efficiency can be considerably improved by information obtained through social learning  ,  and use of spatial memory . The prediction that such mechanisms shape wild boar sociality needs to be further tested.
Repeated and non-random interactions favour cooperative behaviours and facilitate behavioural reciprocity  leading to strong bonds between some animals. Site fidelity occurring over generations result in local clustering of kin or matrilines  —  and increase the chance of frequent interactions with relatives.
In such a scenario, likely to be present in female wild boar which are philopatric  , strong social bonds between relatives can be favoured due to increased indirect fitness benefits  —  , . Our results, showing temporarily stable and kin-targeted females associations, hint at the important role of kin selection in shaping social relationships among female wild boar. Interestingly, interactions among kin were not a major factor shaping wild boar sociality in the heavily harvested population where large proportion of females was removed annually .
This contrasting results raise questions about indirect social effects of removal and their consequences for population dynamics which require further comparative studies.
In contrast to females in our study, associations of adult males with other males and females were dynamic and short-lived, which is consistent with the solitary lifestyle of adult male boars described previously  ,  , .
Genetic structure can emerge as a by-product of philopatry through a passive process of localised relatedness accumulation  , . However, spatial segregation in this study did not entirely explain the observed kin-based structure.
Indeed, our fine-scale analysis of association preferences showed that spatial segregation did not fully account for the observed grouping patterns. Finally, genetic data showed that preferential, kin targeted, associations persisted in the population regardless of spatial proximity.
Our results show that kin-directed social preferences in wild boar extend beyond simple spatial proximity and direct mother-offspring ties within groups and thus imply the potential role of kin recognition as a mechanism driving choice of a social partners.
This study demonstrated, for the first time in wild boar, how social preferences of individuals translate into an emergent socio-genetic population structure.
Wild boar population was organised into spatially and genetically structured social units. Genuine, kin-targeted social interactions of females were temporarily stable and extended beyond spatial proximity between individuals, underlying observed social organisation.
Given the natural environment of the study population and its minimally disturbed character, we believe that the observed patterns of social relationships represent a picture of reference of the social structure of wild boar inhabiting the forests of the European temperate zone.

Abstract Individuals can increase inclusive fitness benefits through a complex network of social interactions directed towards kin. Introduction A variety of social systems arise from the attempts individuals make to directly or indirectly maximise their fitness.
