Mader, D. R., & Price, E. O. (1980). Discrimination learning in horses: effects of breed, age and social dominance. J. Anim Sci., 50(5), 962–965.
Abstract: The discrimination learning ability of Quarter Horses and Thoroughbreds was compared by means of visual cues in a three-choice test with food as a reward. Quarter Horses learned significantly faster than Thoroughbreds, and learning progressed more rapidly for both breeds in a second discrimination task. Significant negative correlations were observed between age and rate of learning. Quarter Horses tended to be less reactive than Thoroughbreds, but individual emotional reactivity ratings and learning scores were not correlated. No correlation was found between social dominance and learning scores. Learning studies with horses may provide a better understanding of the behavioral traits that influence trainability in this species.

Houpt, K. A. (1980). Review of some research areas of applied and theoretical interest in domestic animal behavior. Appl. Animal. Ethol., 6(2), 111–119.
Abstract: There are numerous areas worthy of study in the field of domestic animal behavior or applied ethology. In this paper a few areas are offerred as particularly worthy of attention. These areas are worthwhile either because they have received little or no study and are of basic interest or because they have application to current problems of livestock production. The study of cat behavior falls in the former category. Neither the food and water sources, the reproductive success rate nor even the social interactions of cats in the large populations found in both rural and urban environments are known. Pigs as a species have already been the subjects of many behavior studies; nevertheless, there are still gaps in our knowledge of the underlying principles of swine behavior. The physiological basis of maternal behavior, for example, has not been studied in swine or in any domestic species. The sensory basis of udder location by the neonatal piglet deserves study also. Some aspects of olfactory and vocal communication of pigs have been studied, but only one of what may be a large number of pheromones of pigs has been chemically identified. The message conveyed by the vocal interactions between adult swine of the same sex is unknown, as is the role of facial and postural expressions in porcine communication. The two major problems of pig behavior under conditions of intensive livestock management are tail biting and reproductive failure. The application of behavioral techniques to these problems might help to attenuate those problems as well as broaden our understanding of normal pig behavior. Horse behavior has also been a relatively neglected field of study. Of particular interest is the significance of the flehmen gesture used by both mares and stallions in a variety of situations. Flehmen may be related to the function of the vomeronasal organ, but both observational and physiological studies should be performed to verify the hypothesis.
