Abstract and Figures

Objective: Temperament in livestock is one of the significant concerns in animal production. The objective of this chapter is to determine if there is a relationship between hair whorl position and temperament in Chinese Yellow cattle using a questionnaire. In addition, the effect of the raising environment is investigated. Materials and Methods: A total of 122 Chinese Yellow cattle were surveyed in 3 village areas and 4 grassland areas in a northern area of China. For each cattle, an investigator asked the care-person about each item of a temperament questionnaire and determined the facial hair whorl position of each cattle. Hair whorl position was categorized as high, middle, or low in relation to the eyes. Results: The overall distribution was: 20.5% high, 58.2% middle, 13.1% low, 6.6% double, and 1.6% no hair whorl. There was no significant difference between the grassland and village areas cattle in the distribution of whorl position. The scores for grassland areas were significatly higher than those of village areas in terms of “Retentive memory”, “Sensitivity”, and “Timidity”, and lower in “Docility” and “Fortitude”. The scores for the high position tended to be higher than those for the middle plus low positons in terms of “Adaptability” and “Obedience”. On the other hand, there was a tendency for score for the high position to be lower than the other positions in “Excitability”. Significant interaction between area and whorl position was observed in “Friendliness to cattle”. Conclusion: These findings suggest that hair whorl location may be effective in predicting temperament in cattle, but temperament can be influenced by environment and/or handlings.

Introducon
Temperament is an essential factor in selecting livestock.
There must be an interaction between farm animals and
their care-person; the animal–human relationship is par-
ticularly important in animal production. As well as han-
dling by the care-person, the temperament of the animals

ies about the effect of interaction on the safety and quality
of animal handling [1–3]. In the case of cattle, they are easily
fearful of or irritated by the care-person, and consequently
are hard to control during routine work [4]. It is necessary
to exploit easy ways to select animals for submissiveness
because it is challenging to deal with animals that have an
aggressive or excitable temperament. Horse trainers have
noted the position of round hair whorls (trichoglyphs) on
the forehead of horses, and researchers have reported that
hair whorl position can be used to foretell the behavior
of a horse during training [5,6]. Similar to horses, some
investigations suggest the relationship between temper-
ament and position of facial hair whorl in cattle [7–13].
Environmental factors also affect how cattle act during
treatment. Cattle with a timid temperament may be more
fearful and uncontrollable by a care-person when encoun-
tering a novel situation. On the contrary, animals with an
unagitated temperament may grow accustomed to a new
environment and handling [14]. Therefore, it is essential

North China types) [15,16]. They contribute to not only
beef production but also the improvement of meat quality
in China [17]. However, little is known about the temper-
ament of Chinese Yellow cattle. The objective of the pres-
ent study is to determine whether there is a relationship
between temperament and position of facial hair whorl
in cattle using a questionnaire. Hair whorl position could
then possibly be used to foretell future temperament traits
in cattle. Besides, the effect of the raising environment is
investigated.
Materials and Methods
The survey was conducted at 7 locations (3 village areas

(Fig. 1; Table 1).
A total of 122 Chinese Yellow cattle were used in this
survey: 9 heifers, 20 primiparae, and 93 multiparae (Table
1). Cattle in the village areas were reared in nearby pas-
tures in the daytime and kept in their barn at night. In the
grassland areas, they were raised fulltime in the prairie
away from the village areas. It was assumed that there
were few genetic differences between the cattle at the two
locations because the owners of the cattle at both locations
buy and sell their cattle from and to each other.
The questionnaire was designed to measure the person-
ality of the cattle in general (Table 2). The questionnaire

It is reasonable to consider that cattle in a village may grow
accustomed to various stimulations and become insensi-
ble because there are many stressors (bustle) in the rear-
ing environment of a village.
In terms of the effect of whorl positions, the scores for
high position tended to be higher than those for the mid-
dle plus low positions in “Adaptability” and “Obedience”
(p < 0.1). On the other hand, there was a tendency for the
score of high position to be lower than other positions
in “Excitability” (p < 0.1). In terms of the relationship

effect was also detected (p < 0.001). Besides, the score for
the high position for cattle in the village areas was sig-

a tendency in interaction (area × whorl position) was
detected (p < 0.1).
The facial whorl position of cattle is associated with
temperament and behavior [7,8,19] and maybe of value
in selective breeding for a calm temperament [22]. The
present results indicated that cattle with facial hair whorls
located above the eyes tended to be more adaptable and
obedient, and less excitable in the questionnaire scales
(Table 4). There was a similar report that Holstein bulls
with high-placed whorls were more behaviorally restless
in the crush as measured on an ordinal rating scale [9,23].
Therefore, hair whorl location could be used to predict the
temperament during routine management in frequently
handled cattle.
Temperament prediction using whorl positions in
cattle, however, was affected by the effect of the environ-
ment (Table 4). Although a post-hoc analysis did not indi-

“Curiosity,” it is likely that the cattle with middle and low
hair whorls were more curious than the ones with high
hair whorls in the grassland areas. It seemed that the envi-

because, as mentioned earlier, cattle with facial hair whorls
located above the eyes seemed to be more excitable. On
the other hand, cattle with high facial hair whorls were
friendly with other cattle. Although unclear, these results
indicate that temperaments are easily affected by the envi-
ronment and handling [24,25].
Conclusion
The current study suggests that hair whorl location may be
useful in predicting the temperament in cattle, but temper-

Chapter
Different tests have been developed for evaluating the temperament of cattle, pigs, and sheep and some studies appear to have conflicting results. This may be due to confusion between the basic emotional systems of fear and separation distress (panic). Methods used for temperament tests can alter results such as how tightly an animal is restrained in a squeeze chute during temperament evaluation. Animals with a more reactive (fearful) temperament will exhibit greater agitated behavioral reactions when suddenly confronted with novel objects. Animals can be habituated to new things but learning is very specific. Habituation to one type of strange object may not transfer to other types of objects. Animals with smaller-diameter leg bones and slender bodies may be more reactive (fearful). Facial hair whorl position is related to a vigilant temperament, and it may be more evident in populations with more diverse genetic backgrounds.

This study aimed to assess the relationship between stockperson behavior and buffalo behavior. The research was carried out in 27 buffalo farms. The behavior of stockpeople and animals during milking and the avoidance distance at the feeding place were recorded. Recordings were repeated within one month to assess test-retest reliability. A high degree of test-retest reliability was observed for all the variables with Spearman rank correlation coefficients (rs) ranging from 0.578 (p = 0.002, df = 25) for the number of kicks performed during milking to 0.937 (p < 0.001, df = 25) for the percentage of animals moving when approached by ≤ 0.5 m. The number of negative stockperson interactions correlated positively with the number of kicks during milking (rs = 0.421, p < 0.028, df = 25) and the percentage of animals injected with oxytocin (rs = 0.424, p < 0.027), whereas the percentage of negative stockperson interactions correlated positively with the percentage of buffaloes moving when approached at a distance >1 m (rs = 0.415, p < 0.031, df = 25). In a subsample of 14 farms, milk yield was correlated positively with the number of positive interactions (rs = 0.588, p < 0.027, df = 12) and correlated negatively with the number of steps performed by the animals during milking (rs = −0.820, p < 0.001, df = 12). This study showed that the quality of stockpeople interactions may affect buffalo behavior and production.

Title of the paper: Method to assess the learning ability of group-housed calves and results of visual discrimination tasks Assessing the sensory capacity and learning ability of farm animals will be of increasing importance for the evaluation of animal welfare in order to develop new efficient farming technologies which seriously consider the animals' well-being. The more-arm-maze test using optic signalling proved to be a useful method to assess the learning ability of singel or group-housed calves. Each test box consisted of 3 Stands per calf arranged side by side (stand dimensions: 1.00 m long, 0.30 m wide and 1.50 m high, wooden walls). The Stands could be distinguished by coloured lamps or black visual patterns of different shapes, projeeted on a white plastic panel above the entrance as Stimuli. Chosing the right (conditioned) Stimulus the calves were rewarded by milk (unconditioned Stimulus) when suckling at the dispenser. Given a random expectation of 33%, the calves reached at least 70% correct choiees already at the 4th test day.

Managing livestock near Yellowstone National Park has become an increasing challenge since conservation of wolves restricts ranchers from interfering. Even though wolves are beneficial for the ecosystem, rising predation incidences on livestock (depredations) create animosity in local farmers. Temperament selection of cattle, measured by the facial hair whorl pattern (HW)1, occurred during the last 15 years and the industry prefers calmer temperament animals. Six HWs occur in cattle (high, middle, low, abnormal, multiple and none), which are mutually exclusive and can be identified by using the eye-line as a reference point. We analyzed depredation of calves near Council, ID in 2011. A herd of 588 Black Angus × Charolais crossbreds (age range: 5 - 17 years) was observed. By analyzing the HW and age of cows in relation to depredations, we could identify a connection between these three factors (P

Based on 20 years of personal experience, this author describes three steps for improving the handling of hogs and cattle: selecting animals with a calm temperament, correcting facility problems that impede livestock movement, and training handlers. To solve animal handling problems, veterinarians must determine if the difficulties arise from one or more of the following factors: 1. an animal temperament problem 2. a facility problem, or 3. a personnel problem. During the past few years, I have observed an increasing number of handling problems caused by nervous, flighty, excitable hogs and cattle. Both producers and seed stock breeders should be encouraged to select animals with a calm temperament. Animals balking and refusing to move through a chute or other facility can also be caused by a wide array of facility defects, ranging from major mistakes in design to easily corrected problems such as inadequate lighting. The most common problems related to personnel are rough handling, excessive prodding, and overcrowding of animals in a crowd pen. Cattle and hogs remember bad experiences, and animals that have been handled roughly become more difficult to handle in the future.(1,2) Successful identification and correction of factors that contribute to animal handling problems can help produce better quality meat and provide a safer environment for both the animals and their handlers. Agitation and excitement during handling shortly before slaughter can increase the occurrence of meat-quality defects (pale soft exudative pork and dark cutting in beef). Both of these conditions reduce the quality and value of the meat.

Precision livestock farming affects the nature and frequency of farmers’ daily tasks, specifically in relation to animals. It consequently may modify how farmers consider their animals, the quality of the human-animal relationship and animal welfare. To better understand how new technologies impact human-animal relationships on the farm, a survey was carried out on 25 livestock farms in France. The farms raised dairy cows, gestating sows or broiler chickens using different equipment (sensors associated or not with robots). A qualitative thematic analysis to better identify farmers’ views on the different topics, and secondly a statistical analysis to identify if farmer profiles exist and to better understand the diversity of views were conducted. Most of the farmers expressed satisfaction about working with the new technology because their work becomes easier and allows more control over the management of the animals. Using PLF, the farmers describe a profession that has not fundamentally changed but which involves new tasks, new skills and daily schedules. Three farmers’ profiles were identified. Profile A farmers consider that one cannot talk about a human-animal relationship on their farm, and do not enjoy either touching or talking to their animals. Profile B farmers associate a good human-animal relationship with the animals’ welfare. Profile C is characterized by the central place occupied by animals and associate a good human-animal relationship with an absence of fear on the part of the animals. Farmers motivated by animals (profile C) find in precision livestock farming benefits related to animals, while the others (profiles A and B) find technical benefits detached from the animals. The farmers have room to manoeuvre in how they use the equipment; this can be seen for instance in the degree to which tasks are delegated to the equipment, which can be partial or total. Nevertheless, some farmers expressed concerns regarding the place of the new technologies on the farm, such as the risk of losing their own autonomy or their ability to observe animals and detect problems. Complementary studies could monitor these developments and contribute elements on the role of PLF in the sustainability of livestock farms.

Correlations of calves' temperament with carcass traits were estimated to clarify the genetic relationships between them in Japanese Black cattle. The temperament records for 3128 calves during auction at a calf market were scored on a scale of 1 (calm) to 5 (nervous) as temperament score (TS), and the TS were divided into two groups (TSG): TS 1 and 2 comprised TSG 1, and 3 to 5 constituted TSG 2. Carcass data were obtained from 33 552 fattened cattle. A threshold animal model was used for analyzing the underlying liability for TSG, whereas a linear one was used for TS and carcass traits. The heritability estimates for TS and TSG were 0.12 and 0.11, respectively. On the other hand, moderate to high heritability estimates were obtained for carcass traits (0.40 to 0.68). The temperament scores were negatively correlated with carcass weight, rib thickness and subcutaneous fat thickness (-0.13 to -0.59). In contrast, weak to moderate positive correlations were found between the temperament scores and rib eye area or yield estimate (0.16 to 0.45). The temperament scores and beef marbling score had no correlation. These results showed that it is possible to improve temperament and carcass traits simultaneously.

This pilot study tested for an association between facial hair whorl characteristics and behavioral responses to a fearful stimulus in horses. Nineteen riding horses were categorized based on hair whorl characteristics (height, lateral location, and rotation). Each horse was subjected to a novel object test where an umbrella was suddenly opened. The turning response was recorded. Hair whorl rotation showed a correlation with turning response with P=0.04. Clockwise hair whorls were associated with turning to the right, and counterclockwise hair whorls with turning to the left. There were no significant correlations between hair whorl lateral location or height and direction turned (P>0.05). In conclusion, facial hair whorls may be used as a non-invasive method to predict turning response in horses.

The objective of this study was to evaluate differences in individual calf defence behaviour patterns and maternal protective behaviour of beef cows 24 h after calving. A single herd was observed on an extensive ranch in Colorado, USA. A total of 341 cow-calf pairs (95% Red Angus and 5% Angus x Hereford commercial crossbreds) were used. Each cow-calf pair was approached with an unfamiliar utility vehicle that circled the pair and gradually decreased the distance between the vehicle and the pair. The following four distance measurements were taken with a digital range finder to evaluate maternal protectiveness: (1) the first time the cow raised her head and oriented towards the vehicle; (2) when the cow placed herself between her calf and the vehicle or lowered her head; (3) when the cow vocalised; and (4) closest distance the vehicle approached the cow-calf pair. Calf defence behaviour patterns were recorded as yes/no-classifications and were: (1) protection: the cow positioned herself between the vehicle and her calf; (2) aggression: the cow lowered her head; and (3) the cow vocalised. Hair whorl patterns (HW) on the forehead of each cow were used as a measure of individual differences in temperament. HW pattern and age were collected when the cows were in a squeeze chute during routine handling. HW pattern was classified into the following groups: high, middle, low, abnormal, multiple HWs or no HW. Ninety-nine percent of the cows moved between the vehicle and their calf to protect it, 13.2% lowered their heads as a sign of aggression and 78% vocalised. Cows with high HW or multiple HW oriented towards the vehicle at a further distance, compared to cows in other HW groups (P < 0.05). Cows with a high HW vocalised at a further distance than cows in other groups. Younger cows (3 years) were approached more closely with no behavioural changes than older (5 years) cows (P < 0.05). The results suggest that cows with a high HW and older cows may be more vigilant of their surroundings. Published by Elsevier B.V.

Cryptosporidium spp. and Enterocytozoon bieneusi are important protists in a wide range of vertebrate hosts, causing diarrheal diseases. Cattle are considered potential reservoirs of Cryptosporidium infection in humans, although their role in the transmission of E. bieneusi is not clear. In the present work, 793 fecal specimens from dairy cattle, native beef cattle, and water buffaloes on 11 farms in China were examined for the presence of Cryptosporidium spp. and E. bieneusi using nested PCR targeting the small subunit (SSU) rRNA gene of Cryptosporidium spp. and the internal transcribed spacer (ITS) of E. bieneusi. For Cryptosporidium, 144/446 (32.3%) dairy cattle, 44/166 (26.5%) beef cattle, and 43/181 (23.8%) water buffaloes were PCR-positive. Sequence analysis was successful for 213 of the 231Cryptosporidium-positive isolates; among them 94 had C. andersoni, 61 had C. bovis, 54 had C. ryanae, 2 had a C. suis-like genotype, and 2 had mixed infections of C. bovis and C. ryanae. In dairy and beef cattle, C. andersoni and C. bovis were the most common species, whereas C. ryanae was the dominant species in water buffaloes. The latter species produced SSU rRNA sequences different between cattle and water buffaloes. For E. bieneusi, the infection rate of E. bieneusi in dairy cattle, beef cattle and water buffaloes was 4.9%, 5.4% and 2.2%, respectively. All 35 E. bieneusi-positive specimens were successfully sequenced, revealing the presence of four genotypes: three Group 2 genotypes previously reported in cattle as well as humans (I, J and BEB4) and one Group 1 genotype recently reported in yaks (CHN11). Genotypes I and J were the most common genotypes in dairy and beef cattle, while genotype CHN11 was the only genotype seen in water buffaloes. Thus, the distribution of Cryptosporidium spp. and E. bieneusi in water buffaloes might be different from in dairy and beef cattle in China. These findings indicate that some of the Cryptosporidium species and all four E. bieneusi genotypes identified in bovine animals in the study areas may have zoonotic potential.

Over-selection for production traits has caused animal welfare problems such as feather pecking in hens, tail biting in pigs, and overly aggressive animals. In dogs, over-selection for appearance traits has caused neurological problems such as deafness. Both feather pecking and tail biting may be displaced foraging behaviors, because these behaviors are reduced by providing foraging materials such as straw. Another problem is hunger in broiler breeder hens and breeding sows. Animals that have been selected for rapid growth are also selected for a huge appetite. If breeder animals eat to satiation, they will become obese and have health problems. High-roughage feeds may improve welfare. Researchers suggest that new genetic breeding tools could be used to select against harmful behaviors and still have a productive animal. Breeders must avoid creating animals that will have poor welfare even when they are housed in the best environment.
