“…For example, Lanier and Grandin (2002) reported that cannon bone thickness and width in steers differed significantly depending on their temperament. An objective measure of temperament is facial hair whorl position in relation to the eye level of bulls (Randle, 1998;Lanier et al, 2001) or eye white percentage (Core et al, 2009). Relationship between temperament and bulls facial hair whorl position could possibly be attributed to the fact that during embryonic development, skin, its products and the nervous system arise from the same germ layer, or ectoderm (Fletcher and Weber, 2010).…”

“…Research findings from the last sixteen years (Grandin, et al, 1995;Randle, 1998;Lanier, et al, 2001;Broucek, et al 2007) suggested that facial hair whorl position and shape in bulls may be related to their behaviour, in particular their temperament. This is attributed to the fact that during embryonic development, skin, its products and the nervous system arise from the same germ layer, or ectoderm (Fletcher and Weber, 2010).…”

The aim of the study was to determine the relationship between the behaviour of Holstein-Friesian and Simmental bulls and the quality of their semen. A total of 76 breeding bulls of the Holstein-Friesian and dual-purpose Simmental breeds were investigated. Analysis was made of the response of bulls to humans and other bulls, facial hair whorl position and length, scrotal circumference, and semen characteristics (mean ejaculate volume, mean sperm concentration, and sperm wave motion). The age and breed of the bulls had a statistically significant effect on semen quality, scrotal circumference and the animal's response to an unfamiliar human (P<0.05; P<0.01). The coefficients of correlation between the bull's response to a handler and to other bulls averaged 0.73. In general, only weak correlations were found between behavioural traits of the bulls and quality of their semen. It is worth noting a good correlation (r=0.50; P<0.05) between hair whorl position and sperm concentration in Simmental bulls.Keywords: bulls, behaviour, semen quality STRESZCZENIE Celem pracy było zbadanie relacji między behawiorem buhajów rasy holsztyńsko-fryzyjskiej i simentalskiej a jakością ich nasienia. Badaniami objęto 76 buhajów hodowlanych rasy holsztyńsko-fryzyjskiej i rasy simentalskiej w typie użytkowym mięsno-mlecznym. Analizie poddano reakcje buhajów wobec człowieka oraz innych buhajów, położenie i długość układu włosów na czołach buhajów, obwód moszny oraz cechy ich nasienia (średnią objętość ejakulatu, średnią koncentrację plemników i ruch falowy masy plemników). Stwierdzono między innymi statystycznie istotny wpływ wieku i rasy buhajów na jakość nasienia, obwód moszny oraz reagowanie zwierząt na obcego człowieka (P<0,05; P<0,01). Wartości współczynników korelacji między reakcjami buhajów na osobę z obsługi a reakcjami na inne buhaje wynosiły średnio 0,73. Generalnie wykazano co najwyżej słabe korelacje między cechami behawioru buhajów a jakością ich nasienia. Warto odnotować dobrą korelację (r=0,50; P<0,05) między położeniem układu włosów a koncentracją plemników w nasieniu buhajów simentalskich.

“…For example, the relationship between facial whorl position in cattle and temperament has been well documented (Grandin et al, 1995;Randle, 1998;Lanier et al, 2001), with the location of forehead whorls relative to the medial canthi of the eyes being predictive of reactivity. The relationship between hair patterns and behavioral reactivity can be attributed to the nervous system and skin products sharing a common ectodermal embryonic origin; the ectoderm (Smith and Gong, 1974).…”

“…Hair whorls are a manifestation of hair coat and have been studied in various species, including humans (Gworys and Domagala, 2003;Klar, 2003Klar, , 2005Ziering and Krenitsky, 2003;Weber et al, 2006;Jansen et al, 2007); cattle (Grandin et al, 1995;Randle, 1998;Lanier et al, 2001;Meola et al, 2004;Evans et al, 2005); and horses (Murphy and Arkins, 2004;Górecka et al, 2006Górecka et al, , 2007. The association between hair whorls and brain development reflects a common embryonic ectodermal origin shared by the integument and the nervous system (Smith and Gong, 1974).…”

Hair whorl characteristics were assessed in the domestic dog (Canis familiaris) in the regions of cephalic, cervical (dorsal, ventral, and lateral), thoracic and brachial axillary regions, the chest, shoulders, elbows, ventral abdominal region, and on the caudal thighs (ischiatic). They were classified as simple or tufted, and their position was recorded as the distance between their centers and bony landmarks within each region. The distribution of whorls was explored in a cohort of domestic dogs (N ¼ 120) comprising a variety of breeds and cross-breeds, sourced from shelters (N ¼ 60) and the general public (N ¼ 60). Whorls observed in the majority of dogs in this cohort typically occurred on the chest, brachial axillary region, elbows, and ischiatic region. Atypical whorls were present in fewer than 20% of the population, and included those on the head (cephalic), cervical regions (dorsal, ventral, and lateral), shoulders, thoracic axillary region, and on the ventral abdominal region. The majority of whorls on dogs were classified as simple. In contrast, those located on the elbows and the majority of chest whorls were tufted. The presence and position of whorls were often associated with several variables including coat length and thickness, and the sex and source of the dog. The palpation and hair-cluster method of whorl assessment described in this article is best suited to dogs with short-to-medium coat lengths. The current methodology developed to assess hair whorl characteristics provides a framework for future investigations into any associations between hair whorl characteristics and other canine traits such as temperament.
