  1. Early feeding experiences of piglets and their impact on novel environment behaviour and food neophobia

    Contributor(s):: Middelkoop, Anouschka, Kemp, Bas, Bolhuis, J. Elizabeth

    We studied whether feeding experiences of piglets during lactation influence novel environment behaviour pre-weaning and food acceptance pre- and post-weaning. In a 2 × 2 arrangement, litters (n = 10/treatment) received creep feed as monotonous diet (MO) or four feed items as diverse diet (DD)...

  2. Effect of late gestational feed restriction and glucogenic precursor on behaviour and performance of Ghezel ewes and their offspring

    Contributor(s):: Ahmadzadeh, Leila, Hosseinkhani, Ali, Taghizadeh, Akbar, Ghasemi-Panahi, Babak, Hamidian, Gholamreza

    Maternal undernutrition during pregnancy impairs offspring behaviours and thereby their survival rate indirectly by decreasing lamb birth weight or by deteriorating milk production which in turn limits bonding of the dam with the neonate. This study was aimed to investigate the effect of maternal...

  3. A Survey of Dog Owners' Attitudes toward Treats

    Contributor(s):: Morelli, G., Marchesini, G., Contiero, B., Fusi, E., Diez, M., Ricci, R.

  4. Nutrition and husbandry conditions of Palearctic tortoises (Testudo spp.) in captivity

    Contributor(s):: Bauer, Thomas, Reese, Sven, Koelle, Petra

    Mediterranean and Russian tortoises (Testudo spp.) are popular companion animals (pets), despite ongoing controversy concerning privately keeping reptiles. The arguments used during these controversial discussions have often been based on outdated facts. Therefore, a survey was developed to...

  5. What do calves choose to eat and how do preferences affect behaviour?

    Contributor(s):: Webb, Laura E., Engel, Bas, Berends, Harma, van Reenen, Cornelis G., Gerrits, Walter J. J., de Boer, Imke J. M., Bokkers, Eddie A. M.

    Calves raised for milk or meat are fed diets that differ from feral-herd calf diets and are based on the nutritional requirements of the ‘average calf’. These diets may not meet the dietary preferences of each individual calf. This study explored diet preferences in calves with free dietary...

  6. The importance of diet choice on stress-related responses by lambs

    Contributor(s):: Catanese, Francisco, Obelar, Marianela, Villalba, Juan J., Distel, Roberto A.

    Farm animals are commonly restricted to a reduced array of foods, like total mixed rations or pastures with low species diversity. Under these conditions, animals are less likely to satisfy their specific and changing nutrient requirements. In addition, foods and flavors eaten too frequently or...

  7. Preference and motivation for different diet forms and their effect on motivation for a foraging enrichment in captive Orange-winged Amazon parrots (Amazona amazonica)

    Contributor(s):: Rozek, Jessica C., Millam, James R.

    Motivation tests were conducted to assess preference strength for diet form and a cage enrichment device by Orange-winged Amazon parrots (Amazona amazonica) held in individual cages, N=10. Each cage was equipped with two trough-type feeders, one of which had a hinged lid that required lifting to...

  8. Effects of environmental factors on cribbing activity by horses

    Contributor(s):: Whisher, Lindsay, Raum, Mary, Pina, Lisa, Pérez, Lucia, Erb, Hollis, Houpt, Charles, Houpt, Katherine

    Quantitative measurements of cribbing were made and the environmental influences on the behavior were examined. Licking the substrate preceded cribbing; the horses licked a median of 1.7 times before each cribbing event while eating grain and 1.1 times before each cribbing event while eating hay....

  9. Personality is associated with feeding behavior and performance in dairy calves

    Contributor(s):: Neave, H. W., Costa, J. H. C., Weary, D. M., von Keyserlingk, M. A. G.

  10. ‘I heard a dog cry’: More-than-human interrelatedness, ethnicity and zootherapy in South Korean civil society discourse about dog meat consumption

    Contributor(s):: Dugnoille, Julien

  11. Motivation of naïve feedlot cattle to obtain grain and individual responses to novelty

    Contributor(s):: Van Os, Jennifer M. C., Mintline, Erin M., DeVries, Trevor J., Tucker, Cassandra B.

    Beef cattle may be fattened before slaughter using a high-energy, grain-based diet. Although previous research suggests cattle prefer grain, their motivation to obtain this feed has not been quantified. The objective of this study was to evaluate the motivation of naïve feedlot cattle to consume...

  12. Barren diets increase wakeful inactivity in calves

    Contributor(s):: Webb, Laura E., Engel, Bas, van Reenen, Kees, Bokkers, Eddie A. M.

    Inactivity is a vastly understudied behavioural category, which may reflect positive or negative affective states in captive or domesticated animals. Increased inactivity in barren-housed animals, in combination with an increased or decreased interest in stimuli, e.g. novel objects, can indicate...

  13. Behaviour, stress and welfare of Sprague Dawley rats (Rattus norvegicus) on diet board feeding for 24 months

    Contributor(s):: Laaksonen, Sakari, Nevalainen, Timo, Ketola, Jukka, Hau, Jann, Nieminen, Pentti, Haasio, Kristiina, Kasanen, Iiris, Voipio, Hanna-Marja

    Diet board (DB) feeding aims to reduce the health hazards associated with ad libitum (AL) feeding. Rats have to gnaw wood to detach food from the DB, reducing their food consumption. We studied the welfare effects of DB by measuring faecal corticosterone metabolites (FCM), elevated plus-maze...

  14. Does cribbing behavior in horses vary with dietary taste or direct gastric stimuli?

    Contributor(s):: Albright, Julia, Sun, Xiaocun, Houpt, Katherine

    Concentrated feed diets have been shown to drastically increase the rate of the cribbing, an oral stereotypy in horses, but the specific component causing the rise has not been identified. Furthermore, the mechanism through which feed affects cribbing has not been explored. In the first...

  15. Effects of early experience and alternative feeds on medusahead (Taeniatherum caput-medusae ssp. asperum) intake by sheep

    Contributor(s):: Montes-Sánchez, Juan J., Villalba, Juan J.

    The goals of this study were to test the effects of early experience at grazing medusahead – an invasive unpalatable weed – and the availability of forage alternatives on intake of medusahead later in life by sheep. The study involved two experiments of 10 days each. During Experiment 1, 29...

  16. Acceptance of novel food by horses: The influence of food cues and nutrient composition

    Contributor(s):: van den Berg, M., Giagos, V., Lee, C., Brown, W. Y., Hinch, G. N.

    Compared to ruminants little is known about how horses modulate food intake and learn about flavour-to-post-ingestive consequences. While it has been suggested that due to hindgut fermentation horse⿿s foraging preferences may be largely influenced by sensory input (e.g. volatiles), it has been...

  17. A modeling approach for estimating seasonal dietary preferences of goats in a Mediterranean Quercus frainetto–Juniperus oxycedrus woodland

    Contributor(s):: Manousidis, T., Malesios, C., Kyriazopoulos, A. P., Parissi, Z. M., Abraham, E. M., Abas, Z.

    Goats are characterized as selective feeders due to their specific feeding behavior, thus the study of their seasonal preferences in a Mediterranean oak-juniper ecosystem is of great interest. The current research was conducted in an open oak forest in Megalo Dereio region, northeastern Greece...

  18. Oil sources administered to tambaqui (Colossoma macropomum): growth, body composition and effect of masking organoleptic properties and fasting on diet preference

    Contributor(s):: Pereira, Raquel Tatiane, Paulino, Renan Rosa, de Almeida, Charlle Anderson Lima, Rosa, Priscila Vieira, Orlando, Tamira Maria, Fortes-Silva, Rodrigo

    Tropical fish feeding behaviour and food intake are regulated by a number of environmental factors (e.g.: stress in intensive aquaculture; type or seasonality of food), and also by complex homeostatic mechanisms that involve nutritional requirements. When access to food is not restricted, e.g....

  19. Dietary diversity affects feeding behaviour of suckling piglets

    Contributor(s):: Middelkoop, Anouschka, Choudhury, Raka, Gerrits, Walter J. J., Kemp, Bas, Kleerebezem, Michiel, Bolhuis, J. Elizabeth

    Stimulating solid feed intake in suckling piglets is important to facilitate the weaning transition, exemplified by the positive correlation between pre- and post-weaning feed intake. The present study compared the effect of dietary diversity (i.e. offering two feeds simultaneously) and flavour...

  20. Nutritional state and secondary compounds influence trembling aspen (Populus tremuloides) intake by lambs

    Contributor(s):: Heroy, Kristen Y., St. Clair, Samuel B., Burritt, Elizabeth A., Durham, Susan L., Villalba, Juan J.

    The foraging ecology of mammalian herbivores is determined by plant secondary compounds (PSC) that defend plants against herbivory, by nutrients that are required for maintenance, growth, and reproduction, and by the interaction between these variables. In this study, we explored the influence of...
