“…Thus, the increase in water intake by the animals administered with 50,100 and 200 mg/kg body weight of the extract implied that water was readily consumed by the animals. Similarly, the increased feed consumption by these animals, may also suggests that the doses of the extract enhanced the sense of taste and appetite of the animals after their consumption [53] . In contrast, the decreased water and feed intake by animals treated with 300 mg/kg body weight probably decreased the appetite of the animals and will have consequential effects on their performances.…”

“…Various authors have reported a depression in feed consumption in rabbits (Marai et al, , 2006Habeeb, 1994, 1998;Okab and El-Banna, 2003;Okab et al, 2008). Marai and Habeeb (1998) reported that high environmental temperatures stimulate peripheral thermal receptors to transmit suppressive nerve impulses to the appetite centre in the hypothalamus causing a decrease in rabbit feed intake.…”

This study was conducted to investigate the effect of heat stress (i.e., elevated ambient temperature -Ta; 36 °C ± 3 °C) on growth performance, mortality rate, and on some haematological and biochemical parameters in different categories of gender and age of New Zealand White (NZW) rabbits. Animals were divided into two main groups (control and treatment), in each group there were 56 rabbits: adult females (n = 20), adult males (n = 4), growing females (n = 16), and growing males (n = 16). Results revealed that total and daily feed intake, feed conversion ratio, and total and daily gain in body weight for growing NZW rabbits were affected negatively by elevated Ta. Decreases in feed intake led to less protein biosyntheses and less fat deposition, which led to lower body weight gain. These observations were made in growing and adult rabbits of both genders. Analysis showed that red blood cell (RBC) counts showed alterations. Packed cell volume (PCV) (in adult females and males), white blood cell (WBC) counts (in growing females), lymphocytes (in growing males), monocytes (in growing females and adult males), basophils (in growing females and growing and adult males) were significantly (P < 0.05) decreased, and total proteins (TP) (in adult females), glucose (Glu) (in adult females), and calcium (Ca 2+ ) (in growing males and females) were significantly (P < 0.01) lower in the experimental group. Furthermore, elevated Ta increased the mortality rate (MR) in both age groups. The mortality rate was 30.36% for growing and adult rabbits of the experimental group, compared with 7.14% for the control group, and was 25% for adult compared with 34.38% for growing experimental rabbits. Exposure of NZW rabbits of both ages and genders to elevated ambient temperature (36°C ± 3 °C), negatively affected their internal homeostasis which was reflected in their growth rate and various physiological signs.

“…In Egypt, these effects are accentuated with the high relative humidity during the hottest summer months (Marai et al, 2006). So, as rabbit breeders prefer limiting the breeding season from September to May each year (Marai et al, 1996), rabbit does consequently have a long resting period during which a calculated daily amount of feed (restricted feeding) should be given to keep them in good condition without fattening that would impair their future reproduction (EL-Raffa, 2004).…”

ABSTRACT:A study was conducted to clarify the infl uence of fl ushing or doe relocation as biostimulation methods on oestrus response and subsequent performance on thirty NZW multiparous 10-11-month-old rabbit does after a twomonth resting period in summer. After weaning of their last litter in June, the does were not re-mated and were fed a 100 g daily ration till September, the end of resting period. Then the does were randomly allocated to three groups (10 does/group): a control group (C) in which does remated without oestrus synchronisation, a relocated group (R) and a fl ushed group (F). Relocation consisted of moving does to another room in cages similar to their initial cages 48 h before the intended mating. F does returned to ad libitum feeding one week before mating. After mating, all females were fed and housed under the same conditions. The following parameters were measured: oestrogen level at end of rest period and at mating time, oestrus response parameters, fertility rate, nest quality traits, milk production, litter and kit traits at birth and weaning, and doe weight at mating and kindling. Results obtained revealed that, under the condition of this experiment, fl ushing was superior to relocation as a biostimulation method, since does of F group responded by signifi cantly higher oestrogen level at mating, improved receptivity and fertility rates, higher milk production, and their litters were heavier at birth and weaning. No signifi cant differences were recorded between the different groups for the nest quality traits. On the other hand, doe relocation did not exert any signifi cant effect on oestrus response and subsequent performance of the rabbit does. In conclusion, a short fl ushing period of one week could be good biostimulation method for oestrus synchronisation and improvement of receptivity in multiparous restricted fed rabbit does after a long rest period.
