Title | Foal killing by stallions | Type | Journal Article | ||

Abstract | Feral horses live in social systems similar to those of some species in which infant killing has been reported (e.g. lions), but such behaviour has been reported neither in horses nor in any other ungulate. The results of interviews with owners of free-ranging horses (Camargue breed) are given which show that, though rare, infant killing occurs in this breed, and that it seems to be confined to male foals. It is argued that the observed behaviour cannot simply be considered as pathological, and that close attention should be paid to the possibility that it occurs in wild and feral equids. | ||||

Title | Factors which influence parturition in the mare and development of the foal | Type | Journal Article | ||
Year | 1982 | Publication | Applied Animal Ethology | Abbreviated Journal | Appl. Animal. Ethol. |
Volume | 9 | Issue | 1 | Pages | 7-14 |
Keywords | |||||
Abstract | Observations are reported of 127 foals born to 127 mares. In particular, comparisons are made between the mare's tendency to foal at night, the length of gestation, the weight of the foal and the weight of the foetal membrane, the time taken by the foal to attain a standing position and the time taken by the mare to expel the foetal membrane and the age of the mare and the season. The new facts that emerge from the results are: (a) foals from middle-aged (6–11 years) mares are heavier; (b) variations of gestation length are related to the month of conception (just a trend, not a statistically significant result); (c) time for the foal to stand is related to the foal sex (females: 56.3 minutes; males 70.6 minutes, on average), and to the time taken by the mare to expel the foetal membrane; (d) parturitions take place mainly (80%) during the hours of darkness. In spring, the percentage of night births (85%) is higher than in winter (78%). |

Title | Facilitated transport of oxygen in the presence of membranes in the diffusion path | Type | Journal Article | ||

Abstract | Most of the experimental observations on facilitated transport have been done with millipore filters, and all the theoretical studies have assumed homogeneous spatial properties. In striated muscle there exist membranes that may impede the diffusion of the carrier myoglobin. In this paper a theoretical study is undertaken to analyze the transport in the presence of membranes in the diffusion path. For the numerical computations physiologically relevant values of the parameters were chosen. The numerical results indicate that the presence of membranes tends to decrease the facilitation. For the nonlinear chemical kinetics of the reaction of oxygen with the carrier, this decrement also depends on the location of the membranes. At the higher oxygen concentration side of each membrane the flow of combined oxygen is transferred to the flow of dissolved oxygen. The reverse process occurs at the lower concentration side. Jump discontinuities of the concentration of the oxygen-carrier compound at each membrane are associated with these transfers. The decrement of facilitation is due to the cumulative effect of these jump discontinuities. | ||||

Abstract | Social interactions between individual horses were observed in two herds each comprising a stallion and a number of mares. In one herd, the animals were observed whilst grazing and resting; in the other, nearest neighbours were recorded when the animals were grazing, and social interactions were noted when the animals were feeding on hay. In both herds, the horses showed marked preferences for the company of specific individuals when they were grazing. In one herd, the associations were mainly between individuals that had been associated prior to being put in the herd. In the other herd, this was not the case. A new statistic was produced for testing for specific company preference. In both herds, the stallion was dominant over all mares and never received any aggression. The complete social hierarchy could not be determined for the herd which was observed only when grazing because social contact was restricted to that within groups or pairs that associated together. In the herd to which hay was fed, a non-linear hierarchy existed. Statistics were produced to quantify both the general level of dominance of a horse and its specific dominance or subordination to every other horse. It is suggested that these statistics, and one for quantifying the general aggressiveness of a horse, could be widely used. A principal component analysis allowed the horses to be characterised socially according to aggressiveness, their attitude to other horses and their attractiveness to other horses. |
