  Title Pair-bonding and companion recognition in domestic donkeys, <em>Equus asinus</em> Type Journal Article
  Year 2013 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 143 Issue 1 Pages 67-74  
  Keywords  
  Abstract Pair and social bonding has been documented in various taxa, where pair formations are often described as being driven by kinship or sexual motivation. However, pair-bonding between unrelated individuals where sexual motivation is not a factor is not well documented. Many social relationships and pair-bonds between members of a dyad are facilitated by each individual's ability to recognise their partner using cues which are characteristic of that particular individual. The aims of this study were i) to investigate the existence of pair-bonding in domestic donkeys and ii) to determine whether members of a dyad could recognise their companion during a Y-maze recognition test. Subjects were 55 unrelated donkeys (38 gelded males, 15 females) in seven groups of mixed or same sex, comprising 4?14 individuals. Spatial proximity (nearest-neighbour) was observed three times a day over a 22-day period. Using a simulation approach based on observed data to generate randomised nearest-neighbour matrices, the statistical significance of social relationships was estimated. Of these, 42 (79.2%) were involved in significantly (p<0.05) non-random nearest-neighbour relationships, most of which were reciprocal pair relationships. Based on the spatial data, 24 of the donkeys which had shown significant reciprocal nearest-neighbour preferences for one individual (companion) were then used in a Y-maze recognition test in which they were presented with a choice of their companion and either a familiar donkey from the same group or an unfamiliar donkey from a different group. Donkeys? spatial location in the Y-maze demonstrated a preference for their companion versus familiar (one sample Wilcoxon signed rank test, W=239, p=0.002) or unfamiliar donkeys (W=222, p=0.041). These results verify anecdotal evidence from donkey handlers that donkeys often form pair-bonds, and show that reciprocal social preference and recognition are the basis of these. Pair-bond formation and companionship among donkeys have potential implications for their management, husbandry and welfare.

  Title Sex differences in equine learning skills and visuo-spatial ability Type Journal Article
  Year 2004 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 87 Issue 1-2 Pages 119-130  
  Keywords Horses; Sex differences; Visuo-spatial ability; Learning  
  Abstract There is evidence of superior visuo-spatial ability in males compared to females in most species investigated to-date. However, no known studies have addressed this issue in the equine. Equine visuo-spatial ability was investigated using a novel test apparatus with a sample of 62 horses (males=34 and females=28) during a series of six tests, where the horses were required to access a food source. The test apparatus consisted of a series of four adjacent stalls, each of which had a feed bin and a moveable barrier. The test apparatus was designed such that the breastplate barriers controlled and limited access by the horses to feed bins in all but one stall during each test. Male horses performed such that there were significant differences (P<0.05) in the ability of the subjects to complete all six tests in a mean time of 30 s or less per test. There were significant differences in mean completion times for male subjects between test 1 and test 2 (P<0.05), test 1 and test 3 (P<0.001), test 1 and test 4 (P<0.05) and test 1 and test 5 (P<0.05). There were no significant differences in mean completion times between any of the six tests for female subjects. Males had a lower mean total number of errors during all tests. Male horses also successfully completed significantly more tests than females (P<0.05). These results provide the first behavioural demonstration of superior visuo-spatial ability in male horses, similar to that reported in other species.

  Title Idiosyncratic motor laterality in the horse Type Journal Article
  Year 2005 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 91 Issue 3-4 Pages 297-310  
  Keywords Horse; Idiosyncratic motor behaviour; Laterality; Sidedness  
  Abstract Idiosyncratic motor behaviour was investigated during four experimental procedures in 40 horses (males = 20, females = 20) to establish if horses revealed evidence of significant right or left laterality. The experimental procedures included (1) detection of the preferred foreleg to initiate movement (walk or trot), (2) obstacle avoidance within a passageway (right or left), (3) obstacle avoidance when ridden and (4) idiosyncratic motor bias when rolling. The influence of the horses' sex on both the direction and the degree of the laterality was explored within and between experimental procedures. The findings showed that the direction, but not the degree of idiosyncratic motor preference in the horses was strongly sex-related. Male horses exhibited significantly more (t = 3.74, d.f. = 79, P < 0.001) left lateralised responses and female horses exhibited significantly more (t = -6.35, d.f. = 79, P < 0.01) right lateralised responses. There was also significant positive correlation (P < 0.05) between four of six possible inter-experimental relationships. The results suggest two discrete trends of laterality associated with the sex of the horse. The primary cause of idiosyncratic motor laterality may be genetically predetermined, influenced by environmental factors or a combination of these two and the current findings may support the development of sex-specific training schedules for the horse. Further, work in this area might assist in defining the mechanisms of brain hemisphere lateralisation and allocation of cognitive function in the horse.

  Title Dairy cows' fear of people: social learning, milk yield and behaviour at milking Type Journal Article
  Year 2001 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 73 Issue 1 Pages 15-26  
  Keywords  
  Abstract We examined the effects of the presence of an unfamiliar, a gentle or an aversive handler during milking on behaviour and milk yield, and whether cows can learn to approach or avoid a handler by observing the neighbouring cow?s responses. In Experiment 1, Danish Friesian cows (n=16) were treated gently (offering hay and concentrates) by one handler and aversively (hit every 15s on the head with the hand) by another handler for six periods of 2min each. The two handlers wore different coloured overalls, and each cow received either gentle or aversive treatment in the first week and the other treatment the following week. All cows kept a longer distance to the aversive than to the gentle handler in a 1min test after treatment. Milk yield and residual milk did not differ when the aversive or the gentle handler was standing in front of the cow during milking, although the cows moved their legs and tail less when the aversive handler was present. When an unfamiliar person was standing in front of the cows during milking, behaviour and milk yield did not differ from control milkings. Cows and heifers (n=10) that had observed their neighbours receiving gentle treatment by one handler and aversive treatment from another handler did not differ in the distance they kept from these two handlers. In Experiment 2, cows (n=15) that had observed the neighbours receiving a gentle treatment (eight times for 2min) kept a shorter distance to that handler after treatment of their neighbours, and the distance they kept was correlated with the distance kept by the neighbouring cows. This suggests that responses of observer cows may be affected by the responses of the cows being treated. The cows rapidly learned to avoid an aversive handler, but although the cows showed clear avoidance response to the aversive handler there was no effect on milk yield when the aversive handler was present at milking.

  Title Preference of horses for grass conserved as hay, haylage or silage Type Journal Article
  Year 2007 Publication Animal Feed Science and Technology Abbreviated Journal  
  Volume 132 Issue 1-2 Pages 66-78  
  Keywords Horse; Preference; Silage; Haylage; Hay  
  Abstract The purpose of this experiment was to determine if different methods of forage conservation influenced horse preference for conserved forages. Silage, haylage with two different dry matter (DM) levels and hay was produced from the same grass crop at the same botanical maturity stage. Four horses were simultaneously offered the four forages (1 kg DM of each forage) once daily for four consecutive experimental periods, each period consisting of 5 days. On each experimental day, the horses were observed for 2 h and their first choice, eating time and forage consumption was registered for every forage. The number of times each horse depleted individual forages and the number of times each horse tasted or smelled a forage, but left it in favour of another forage, was also recorded. Silage had the highest rate of consumption (0.90 kg DM/day, S.D. 0.14) and longest eating time (28.4 min/day, S.D. 5.16). Hay had the lowest rate of consumption (0.23 kg DM/day, S.D. 0.14) and shortest eating time (6.8 min/day, S.D. 4.08), while the haylages were intermediate. Silage was the first choice 72 of 84 times (85%). Hay was never completely consumed and silage was never left in favour of another forage after smelling or tasting it. We conclude that the forage conservation methods had an impact on horse preference in favour of silage, even if the reason for silage preference remains to be explained.

  Title Apes save tools for future use Type Journal Article
  Year 2006 Publication Science (New York, N.Y.) Abbreviated Journal Science  
  Volume 312 Issue 5776 Pages 1038-1040  
  Keywords Animals; Association Learning; *Cognition; *Evolution; *Mental Processes; *Pan paniscus; Pan troglodytes; *Pongo pygmaeus  
  Abstract Planning for future needs, not just current ones, is one of the most formidable human cognitive achievements. Whether this skill is a uniquely human adaptation is a controversial issue. In a study we conducted, bonobos and orangutans selected, transported, and saved appropriate tools above baseline levels to use them 1 hour later (experiment 1). Experiment 2 extended these results to a 14-hour delay between collecting and using the tools. Experiment 3 showed that seeing the apparatus during tool selection was not necessary to succeed. These findings suggest that the precursor skills for planning for the future evolved in great apes before 14 million years ago, when all extant great ape species shared a common ancestor.

  Title Husbandry and Management Practices in Domestic horses in Northern Nigeria and their Clinical Implications Type Conference Article
  Year 2012 Publication Proceedings of the 2. International Equine Science Meeting Abbreviated Journal Proc. 2. Int. Equine. Sci. Mtg  
  Volume in press Issue Pages  
  Keywords  
  Abstract This study was conducted to identify common husbandry and management practices associated with domestic horses in Northern Nigeria. Fifty (50) of the horse was purposely selected as units of analysis. Primary data was generated by means of a pre-tested, semi-structured questionnaire administered to the sampled respondents. A simple inductive statistics was applied to the primary data. The study revealed that the whole facilities studied 50(100%) had a prior experience with horses. A large number of horses, mostly West African Dongola and West African Barb are kept solely for pleasure or ceremonial purposes (60%). While the other breeds of horses like Argentine (6%) and South Africa polo ponies (2%) are kept for polo. Recently, the Sudan country-bred (4%) and Western Sudan pony (6%) have found a place in West African polo. Other breeds found within the facilities studied are Argentine criollo; Nigerian ponies and various crosses. Only 10% of the facilities had breeding stocks with only 2% carrying out artificial insemination while 8% do natural mating. The housing management system includes stables (40%) and open fields (60%) where horses are tethered. Bedding materials includes straws (50%); sand (20%) and wood shavings (30%). Feed grade provided include a combination of rations-bran; cracked grain and hay (40%), Bran; cracked grain and legumes (48%) and Bran and hay (12%), all feed combination administered along with fresh grass. Watering and feeding practices involves provision of feed and water twice daily (50%) and while others provide it adlib (25%). Feeding horses with various additives accounted for 19% of the studied facilities. The health status as shown by the body condition score ranges from II-IV/V (88%) of the population studied. Routine dental care is regular (30%) with all the facilities while others (70%) are not irregular. Grooming is common in all the facilities especially within the performance horse circle. Routine hoof care including trimming and shoeing is common in 26% of the facilities while hoof trimming without shoeing is a common practice in 74% of the facilities. Orthodox medicine practiced in 80% of the studied area. While ethnoveterinary consist of 10%, while a combination of orthodox and ethnoveterinary medicine was common in 10% of the study area. Vaccination against African horse sickness equine influenza and tetanus is common in the various equine communities.Though 16% of the population do not vaccinate against any known disease. Parasite control program include pasture hygiene (4%); interval dosing (10%); continuous in-feed (4%); selective dosing (40%) and strategic dosing constitute 42%. Exercise is a common practice but intensity and duration is not strictly adhered to especially during tendon injuries. Manure management differs from facility to facility- some dispose manure within the facilities (40%) while others dispose it outside the facilities (60%). A number of clinical signs like limping, coughing, ocular and nasal discharge, swellings on the body, abnormal mucous membrane, fever, ventral oedema and reluctance to move, foul respiratory odour was observed. Clinical cases like laminitis; pigeon fever; bran disease; colic; African horse sickness; exertional rhabdomyolysis; sinusitis; piroplasmosis; dermatomycosis and tumours was observed. KW -

  Title A note on yearling horse ingestive and agonistic behaviours in three concentrate feeding systems Type Journal Article
  Year 2007 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 106 Issue 1-3 Pages 167-172  
  Keywords Horse; Feeding; Agonistic behaviour; Social behaviour; Sex differences  
  Abstract The objective of this study was to compare behaviours of yearling horses fed concentrates under each of three management systems. Over two consecutive years, 16 yearling horses (n = 8/year; 4 fillies, 4 geldings, full siblings between years) were observed over a 60-day trial period/year at 15:30 h each day. The experimental design consisted of three factors (sex, feeder type, and year); repeated measures on feeder type: tire feeders (control system), individual tub feeders, and manger feeders. Frequency of agonistic interaction was affected by feeder type and sex. Fillies performed more than three times the total number of agonistic behaviours per feeding session as geldings. In both years, horses spent the most time eating and had the fewest agonistic interactions when fed in tire feeders.

  Title Measurement of corticosterone metabolites in birds' droppings: an analytical approach Type Journal Article
  Year 2005 Publication Annals of the New York Academy of Sciences Abbreviated Journal Ann N Y Acad Sci  
  Volume 1046 Issue Pages 17-34  
  Keywords Animals; Birds/*metabolism; Corticosterone/*analysis/metabolism; Feces/*chemistry; Gas Chromatography-Mass Spectrometry; Immunoassay; Molecular Structure; Reproducibility of Results; Sensitivity and Specificity  
  Abstract Fecal steroid analyses are becoming increasingly popular among both field and laboratory scientists. The benefits associated with sampling procedures that do not require restraint, anesthesia, and blood collection include less risk to subject and investigator, as well as the potential to obtain endocrine profiles that are not influenced by the sampling procedure itself. In the feces, a species-specific pattern of metabolites is present, because glucocorticoids are extensively metabolized. Therefore, selection of adequate extraction procedures and immunoassays for measuring the relevant metabolites is a serious issue. In this review, emphasis is placed on the establishment and analytical validation of methods to measure glucocorticoid metabolites for a noninvasive evaluation of adrenocortical activity in droppings of birds.
