  1. Importance of alternative foods on the persistence of flavor aversions: implications for applied flavor avoidance learning

    Contributor(s):: Kimball, B. A., Provenza, F. D., Burritt, E. A.

    We added a novel flavour, citric acid (CA), to a familiar test diet and conditioned an aversion in lambs to the flavored diet using lithium chloride. In 1 h feeding trials, we examined the roles of a novel flavour cue, choice and nutritional quality of alternatives on the persistence of an...

  2. Overcoming food neophobia in domestic ruminants through addition of a familiar flavor and repeated exposure to novel foods

    Contributor(s):: Launchbaugh, K. L., Provenza, F. D., Werkmeister, M. J.

    Food neophobia, observed as a decreased intake of novel foods, can cause significant livestock production losses. In the transition from rangeland to feedlot, livestock are usually offered novel diets that they sample cautiously, gradually increasing intake. This familiarization period can slow...

  3. Taste threshold determination and side-preference in captive cockatiels ( Nymphicus hollandicus )

    Contributor(s):: Matson, K. D., Millam, J. R., Klasing, K. C.

    The taste thresholds of caged cockatiels (Nymphicus hollandicus) for aqueous solutions of sodium chloride, citric acid, and sucrose were studied using two-choice taste-preference tests. The effects of location on the threshold were tested by putting the flavoured solution in either the preferred...

  4. Discriminating among novel foods: effects of energy provision on preferences of lambs for poor-quality foods

    Contributor(s):: Villalba, J. J., Provenza, F. D.

    A study was conducted to better understand how lambs discriminate among novel foods based on flavour and post-ingestive effects. The manner in which temporal sequence of food ingestion and post-ingestive feedback affected preference when lambs were fed flavoured wheat straw (a poorly nutritious...

  5. Taste reactivity patterns in domestic cats ( Felis silvestris catus )

    Contributor(s):: Bos, R. van den, Meijer, M. K., Spruijt, B. M.

    The present study is aimed at finding taste reactivity patterns in domestic cats (Felis silvestris catus) which reflect 'liking' or perceived palatability. Three groups of nonstressed cats living in households (Netherlands) were formed which a priori were expected to differ in motivational state...

  6. Exploiting flavour preferences of common marmosets to increase palatability of a dry pellet diet

    Contributor(s):: Caldwell, C. A., Watson, C. F. E., Morris, K. D.

    Although commercially available complete diets exist for common marmosets, the animals' consumption of these diets (available in dry pellet form) is typically very low. Increasing consumption of the pellet diet could have positive consequences for the welfare of the marmosets as the pellets are...

  7. Effect of early dietary experiences on the development of feeding preferences in semi-intensive sheep farming systems - a brief note

    | Contributor(s):: Simitzis, P. E., Bizelis, J. A., Deligeorgis, S. G., Feggeros, K.

    The crucial role of the periweaning period in the development of lamb feeding preferences was examined in the present study. Twenty-four female lambs were fed with a commercial diet, supplemented with oregano essential oil (1 ml/kg) between the 15th and 55th day of their life, in the absence of...

  8. Variety of foods and flavors affects selection of foraging location by sheep

    | Contributor(s):: Scott, L. L., Provenza, F. D.

    The effect of variety of dietary flavours and ingredients on selection of foraging locations by sheep was studied. It was hypothesized that lambs would forage in locations that offered a variety of flavours and/or nutritional characteristics and on feeds that differed from their basal diet. This...

  9. Flavour preference conditioned by postabsorptive propionate and acetate in wethers

    | Contributor(s):: Sutoh, M., Imura, T., Tsukada, H., Yamada, A.

    Previous studies have indicated that intraruminal infusions of acetate and propionate condition flavour preference in sheep. Three experiments were conducted to evaluate and compare the preference-reinforcing effects of postabsorptive acetate and propionate. Eight wethers were used in...

  10. Dietary flavor modifies oil preferences in the chicken

    | Contributor(s):: Mabayo, R. T., Okumura, J., Furuse, M.

    A series of experiments using chickens previously fed on a flavoured diet containing 3% long-chained triacylglycerol (LCT) or an unflavoured diet containing 20% medium-chain triacylglycerol (LCT) were conducted to determine the role of dietary flavour on the feed selection of flavoured LCT (FLCT)...

  11. Effects of a flavor and food restriction on the response of sheep to novel foods

    | Contributor(s):: Provenza, F. D., Lynch, J. J., Cheney, C. D.

    2 methods were used to encourage sheep to eat unfamiliar feeds quickly: restricting the amount of feed offered, or increasing the familiarity by adding a flavour (onion) to novel feeds. Sheep, 37 kg, were given lucerne pellets 750 (slightly in excess of maintenance and 34% of ad libitum), or 1500...

  12. Selection and acceptance of flavours in concentrate diets for stabled horses

    | Contributor(s):: Goodwin, D., Davidson, H. P. B., Harris, P.

  13. Sensory varieties in concentrate diets for stabled horses: effects on behaviour and selection

    | Contributor(s):: Goodwin, D., Davidson, H. P. B., Harris, P.

    There is little published information about feeding behaviour of horses presented with concentrate diets and whether restricted variety affects foraging behaviour on concentrate diets is currently unclear. This study investigated the effects of sensory variety on diet selection and behaviour of...

  14. Do herbivores associate flavours with specific consequences in flavour aversion learning?

    | Contributor(s):: Kimball, B. A., Billings, V.

    Goats were first offered a novel, maple-flavoured diet paired with either lithium chloride (LiCl) or oxalic acid (OA) delivered intraruminally. Aversion to maple diet persisted for 6 days, regardless of toxin. Following a 10-day intermission, aversion to maple diet was reacquired (spontaneous...

  15. Herbivore experience with plant defense compounds influences acquisition of new flavour aversions

    | Contributor(s):: Kimball, B. A., Nolte, D. L.

    Multiple experiments were conducted with a mammalian herbivore to determine how experience with plant secondary metabolites (terpenes and tannins) influenced acquisition of new aversions to diets containing these same plant metabolites. Goats (Capra aegagrus hircus) were employed as behavioural...

  16. A note on increased intake in lambs through diversity in food flavor

    | Contributor(s):: Distel, R. A., Rodriguez Iglesias, R. M., Arroquy, J., Merino, J.

    Because preferences for food flavor decline during and after a meal, intake could be increased by offering the same food in different flavors simultaneously. The objective of this study was to determine the effects of offering the same hay with different flavors on forage intake by lambs....
