Drinking behaviour in sows kept outdoors during the winter months
Contributor(s):: Andersen, Heidi Mai-Lis, Pedersen, Lene Juul
In the light of the EU regulation, “pigs must have permanent access to a sufficient quantity of fresh water” and the practical problems it provides farmers during winter to keep water free of ice, the aim of this study was to investigate the influence of periods with frost on the diurnal pattern...

Ration composition affects short-term diurnal feeding patterns of dairy heifers
Contributor(s):: Greter, Angela M., von Keyserlingk, Marina A. G., DeVries, Trevor J.
The objective of this study was to compare the short-term (first week of adaptation to a new ration) behaviour of dairy heifers when fed a low-concentrate, high-forage ration ad libitum to when fed a high-concentrate ration in a limited amount followed by ad libitum access to straw for the...

Agonistic behaviour, skin lesions and activity pattern of entire male, female and castrated male finishing pigs
| Contributor(s):: Bunger, B., Schrader, L., Schrade, H., Zacharias, B.
Fattening of intact boars is the least invasive alternative to the detrimental welfare effects of surgical castration of piglets. However, beside problems such as boar taint the divergent agonistic and sexual behaviour of boars may impair the pigs' welfare during fattening. To evaluate the...

Diurnal rhythms, locations and behavioural sequences associated with eliminative behaviours in fattening pigs
| Contributor(s):: Guo, YuGuang, Lian, XinMing, Yan, PeiShi
Understanding eliminative behaviours in pigs is very important to maintain individual and pen cleanliness. In this experiment, twenty fattening pigs were housed in four concrete floor pens with a floor space of 3.25 m 2 per pig and free accessibility of outdoor runs. We studied the diurnal...

Diurnal and seasonal variations of roaring activity of farmed red deer stags
| Contributor(s):: Pepin, D., Cargnelutti, B., Gonzalez, G., Joachim, J., Reby, D.
Various environmental and social parameters are known to affect the roaring activity of the red deer (Cervus elaphus) stags, but their influence is difficult to estimate in the field. We consequently studied the diurnal changes in roaring activity of three adult stags kept in separate paddocks...

Diurnal patterns of intake rate by sheep grazing monocultures of ryegrass or white clover
| Contributor(s):: Orr, R. J., Penning, P. D., Harvey, A., Champion, R. A.
The effects of time of day on the ingestive behaviour of groups of 5 sheep grazing monocultures of ryegrass (Lolium perenne cv. Parcour) or white clover (Trifolium repens cv. Kent Wild White), were measured over periods of 1 h starting at 07.30, 11.30, 15.30 and 19.30 h in August 1993. Grazing...

Diurnal rhythm of feather pecking behaviour and condition of integument in four strains of loose housed laying hens
| Contributor(s):: Kjaer, J. B.
2400 chickens from 4 commercial strains, Lohmann Selected Leghorn (LSL), Norbrid 41 (NB), Lohmann Brown (LB) and ISA Brown (ISA) were reared and kept in aviary systems. Feather pecking behaviour was recorded by time sampling from video recordings at 38 weeks of age and condition of plumage, keel...

Effects of qualitative and quantitative feed restriction on the activity of broiler chickens
| Contributor(s):: Nielsen, B. L., Litherland, M., Noddegaard, F.
Diurnal patterns and time courses of activity were investigated in groups of fast-growing broilers subjected to different levels of qualitative and quantitative feed restrictions. Eight groups of 225 female Ross 208 broiler chickens were reared from 1 to 57 days of age in straw-bedded floor pens...

Twenty-four hour activity budgets and patterns of behavior in captive ocelots (Leopardus pardalis)
| Contributor(s):: Weller, S. H., Bennett, C. L.
Activity budgets of captive ocelots (Leopardus pardalis) were assessed from over 547 h of observational data obtained from six ocelots; two females at the Dallas Zoo (Dallas, TX), two females at the Caldwell Zoo (Tyler, TX) and a male and female at the Fossil Rim Wildlife Centre (Glen Rose, TX)....

Diurnal behavioural patterns in the houbara bustard (Chlamydotis undulata) in captivity: effects of temperature and daylength
| Contributor(s):: Jacquet, J. M., Launay, F.
Twenty adult male houbara were allocated to 4 groups: 12 h light, 12 h dark (12L:12D) at 20 degrees C or 30 degrees C, 8L:16D at 20 degrees C and 16L:8D at 20 degrees C. The temperature was constant and food and water were available ad libitum. The birds were observed for 96 h and behaviour was...

Diurnal distribution of dairy cow defecation and urination
| Contributor(s):: Aland, A., Lidfors, L., Ekesbo, I.
This study investigated the diurnal distribution of urination and defaecation in tied dairy cows with reference to management routines and milk yield/feeding intensity. A total of 16 lactating cows and 4 heifers were videotaped during 9 consecutive 24-h periods. The cows had a mean of 16.1...

Effects of calcium deficiency in broilers on the use of outdoor areas, foraging activity and production parameters
| Contributor(s):: Christensen, J. W., Nielsen, B. L., Young, J. F., Noddegaard, F.
The present experiment investigated the effects of a calcium deficient diet on the use of outdoor areas, foraging activity and production parameters in two strains of slow-growing broilers (i657 and a Labresse cross). The birds were housed as day-old in an indoor system of 2x8 groups of each 111...

The temporal patterns of food intake and allelomimetic feeding by pigs of different ages
| Contributor(s):: Liang Chou, Hsia, Wood-Gush, D. G. M.
The feeding behaviour of 4 castrated boars was studied over 24 hr using a photoelectric cell and continuous recorder at 4 body-weight stages, viz. 20, 40, 60 and 80 kg. Two of the pigs were on continuous light, and 2 were on 8.5 hr light and 15.5 hr of darkness. The 2 pigs in each treatment were...

A note on eating behaviour of dairy cows at different stocking systems - diurnal rhythm and effects of ambient temperature
| Contributor(s):: Taweel, H. Z., Tas, B. M., Smit, H. J., Tamminga, S., Elgersma, A.
This experiment was aimed at studying the diurnal rhythm of dairy cows eating behaviour at different stocking systems, and quantifying the effect of daily ambient temperature on this diurnal rhythm. In two experiments carried out in the summer of 2003 in The Netherlands, eight dairy cows were...

Diurnal activity cycles and synchrony in layer hen chicks (Gallus gallus domesticus)
| Contributor(s):: Riber, A. B., Nielsen, B. L., Ritz, C., Forkman, B.
The role of the broody hen under natural conditions with regard to temperature regulation, protection, and affecting the feeding behaviour of the chicks appears irrelevant in commercial production. However, other aspects of the chicks' behaviour may be affected by the absence of a broody...
