  1. Individual variation in the heart rate of piglets; evidence against stable differences

    Contributor(s):: Webster, S. D., Jones, A. R.

    Heart rate was measured in 15 piglets from 5 litters from multiparous Camborough 12 sows, and analysed with respect to individual animal, behaviour (posture, locomotion, aggression and feeding), age, weight, ranked weight, experimental treatment and data collection session (data collection...

  2. Influence of weaning age and an experimental Haemonchus contortus infection on behaviour and growth rates of lambs

    Contributor(s):: Schichowski, C., Moors, E., Gauly, M.

    Four groups of 20 lambs each, differing in weaning age (6 or 13 weeks) and infection with Haemonchus contortus (infection after weaning or simultaneous to weaning), were observed and compared regarding the behaviour before, during and after these procedures. Furthermore the influence on...

  3. Playing and fighting by piglets around weaning on farms, employing individual or group housing of lactating sows

    Contributor(s):: Silerova, J., Spinka, M., Sarova, R., Algers, B.

    In the pig industry, piglets are weaned earlier than in nature. Early weaning has an impact on piglet growth and feeding behaviour, but this may differ, apart from the weaning age, according to the housing environment. Piglets from sow group housing systems (GH), where several litters and sows...

  4. The effects of group size/stocking density on weanling pig performance and behavior

    Contributor(s):: Spicer, H. M., Aherne, F. X.

    77 Yorkshire X Landrace pigs from 10 litters were weaned at 28 days of age and housed in group sizes of 1, 2 or 4 pigs per pen. For the 28-day experimental period, body weight gain and voluntary feed consumption were significantly lower for pigs housed in groups of 4 than for other pigs. The...

  5. Managing 'teat order' in suckling pigs ( Sus scrofa domestica )

    Contributor(s):: Orihuela, A., Solano, J. J.

    Piglets in 34 Hampshire x Large White litters were allowed to establish a natural sucking order (controls) or removed from their mothers during farrowing and assigned to the anterior or posterior region of the sow (heavy and light piglets, respectively) after delivery was complete. The litter...

    Contributor(s):: Nicks, B., Dechamps, P., Canart, B., Istasse, L.

    Standing and lying bouts of 11 fattening bulls were recorded continuously during two 1-week trials. There were 6 Friesian bulls and 5 double-muscled bulls from the Belgian White-Blue breed. At the start of Trial 1, the Friesian and Belgian White-Blue bulls averaged 154.2 and 246.2 kg,...

  7. A preliminary study on the utilization of an onboard watering system by horses during commercial transport

    Contributor(s):: Iacono, C. M., Friend, T. H., Johnson, R. D., Krawczel, P. D., Archer, G. S.

    This study determined if slaughter horses would drink from an onboard watering system in a commercial semi-trailer, provided an estimate of how long water needed to be available, and determined if water consumption reduced weight loss. Three shipments to either Fort Worth or Morton, Texas of...

  8. Group housing of adult silver fox ( Vulpes vulpes ) vixens in autumn: agonistic behaviour during the first days subsequent to mixing

    Contributor(s):: Hovland, A. L., Akre, A. K., Bakken, M.

    Due to farmed foxes' (Vulpes vulpes) social flexibility and possible motivation for intraspecific contact, group housing may act as an alternative housing procedure. Because initial social contact between silver foxes usually involves agonistic displays as a part of foxes' social dominance...

  9. Long-distance transport of pregnant heifers by truck

    Contributor(s):: Lambooy, E., Hulsegge, B.

  10. Maternal responsiveness of sows towards piglet's screams during the first 24 h postpartum

    Contributor(s):: Illmann, G., Neuhauserova, K., Pokorna, Z., Chaloupkova, H., Simeckova, M.

    In this study we focused on sow responsiveness towards piglet screams which are proposed to have an important link to posture changes and early piglet crushing. A sow's responsiveness to screams of her piglets was investigated along the first 24 h after birth, the period of highest mortality, in...

  11. Behaviour and weight changes at weaning and regrouping of pigs in relation to teat quality

    Contributor(s):: Algers, B., Jensen, P., Steinwall, L.

    The relation between body weight and behaviour at weaning and regrouping was investigated in 101 crossbred piglets from birth to 9 weeks old. Weaning and regrouping was performed at weeks 6 and 7, respectively and recorded on video. Weaning and regrouping increased the frequencies of eating,...

  12. Effect of suckling ('restricted suckling') on dairy cows' udder health and milk let-down and their calves' weight gain, feed intake and behaviour

    | Contributor(s):: Froberg, S., Gratte, E., Svennersten-Sjaunja, K., Olsson, I., Berg, C., Orihuela, A., Galina, C. S., Garcia, B., Lidfors, L.

    The aim of this study was to evaluate the effects of restricted suckling (RS) in Holstein cattle on the weight gain, health and behaviour of calves and on udder health and milk let-down in cows compared to artificial rearing (AR). The study was conducted in Mexico. The 27 cows with calves were...

  13. Effects of prenatal handling stress on adrenal weight and function and behaviour in novel situations in blue fox cubs ( Alopex lagopus )

    | Contributor(s):: Braastad, B. O., Osadchuk, L. V., Lund, G., Bakken, M.

    This study investigated the effects of a 1-min daily handling stress given to farmed blue fox females in the last third of gestation on adrenal weight and function in male and female offspring and on behaviour in novel situations. In 10-day-old cubs (n=68), records were made of serum...

  14. Feeding behaviour of yaks on spring, transitional, summer and winter pasture in the alpine region of the Qinghai-Tibetan plateau

    | Contributor(s):: Ding, LuMing, Long, RuiJun, Shang, ZhanHuan, Wang, ChangTing, Yang, YuHai, Xu, SongHe

    Of the present estimated world population of 14.2 million yaks, approximately 13.3 million occur within Chinese territories (Food and Agriculture Organization of the United Nations, 2003). Although there is an extensive bibliography covering the species, few studies have been conducted in the...

  18. The effect of heat incubators on chilled mink kits

    | Contributor(s):: Castella, A., Malmkvist, J.

    Hypothermia is considered a major risk factor increasing kit mortality in farmed mink. We studied the effects of reheating chilled mink kits. From each of 27 litters, three 1-day-old kits were exposed to one of three treatments: (i) chilling and reheating in a farm incubator (INCU), (ii) chilling...

  19. The effects of resource distribution on behaviour in pair housed silver fox vixens ( Vulpes vulpes ) subsequent to mixing

    | Contributor(s):: Akre, A. K., Hovland, A. L., Bakken, M.

    In nature, the way essential resources are distributed is recognized as a potentially important factor influencing the frequency of aggressive interactions between animals. This knowledge is rarely taken into consideration when designing housing environments for social groups of farm animals....

  20. Behaviour and performance of pigs finished on deep bedding with wood shavings or rice husks in summer

    | Contributor(s):: Hotzel, M. J., Lopes, E. J. C., Oliveira, P. A. V. de, Guidoni, A. L.

    Concern that excessive temperatures arising from substrate fermentation could have a deleterious effect on voluntary feed intake and weight gain, especially during the hottest times of the year, might be a barrier to the widespread adoption of deep-bedding systems for pig production in Brazil....
