“…cows, sheep), mechanical or manual milking is used as direct method to measure milk production. Also for rabbits milking machines were developed and described (Lebas, 1970;Schley, 1975;Marcus et al, 1990). Milking or sampling is always done after a 24-hour separation of mother and kits avoiding the free suckling of kits.…”

“…Females have to be treated with oxytocine in order to stimulate the milk ejection. When the females are fixed in a comfortable position with suitable milking equipment, equivalent or higher amounts than that ingested by the kits at one suckling can be collected (Lebas, 1970). This methodology is generally used for the collection of milk from transgenic rabbits (BioProtein Technologies, 2006).…”

This literature review focuses on the milk yield and milk composition of rabbits and the non-nutritional factors affecting both quantity and quality. Actual highly efficient hybrid does have an average daily milk yield of 250 g or 60 g/kg of live weight during the 4-weeks lactation period. However, compared with cow and sow milk, rabbit's milk is much more concentrated in fat (12.9 g/100 g), protein (12.3 g/100 g) and energy (8.4 MJ/kg) which explains the extremely rapid growth of the young (weight × 6 after 3 weeks). Characteristic of rabbit milk is also the nearly absence of lactose (<2 g/100 g). At peak lactation, protein output per kg metabolic weight (13.4 g/day/kg 0.75 ) exceeds even those of Holstein milk cows. The non-nutritional factors having the largest impact on the milk yield are the number of suckling kits, the parity order (primiparous vs. multiparous) and the gestation overlapping degree (rapid decline after 17-20 days of gestation). However, also through the reduction of feed intake, heat stress has a detrimental impact especially when the night temperature remains above 25°C. Rabbit milk lipids are highly saturated (70.4% SFA) due to the high content of C 8:0 -C 12:0 (50% of total FA) and further characterised by nearly equal quantities of oleic and linoleic acid and an w-6/w-3 ratio around 4. Finally some data about the amino acid, milk proteins including the immmunoglobulins, mineral and vitamin composition are presented.

-The influence of a low starch/fibre ratio (S/F) diet given to rabbits and does around weaning on their performance and health status was studied. In the LS group (n = 29 litters), the rabbits were fed a low S/F (0.68) diet (LS diet: 11.7 DE MJ·kg -1 DM) from day 18 to day 44; then they were changed to a fattening diet (F diet: 12.5 DE MJ·kg -1 DM). In the HS group (n = 29 litters), the rabbits were fed a high S/F (0.98) diet (HS diet: 12.6 DE MJ·kg -1 DM) from days 18 to 32 (weaning), and after weaning they received the F diet. From day 18 to weaning, the females and litters were fed the same diet. From day 18 to day 21, after the feed change, the LS females' feed intake dropped (-6%). As a consequence, they lost weight (-4%), and produced less milk from days 21 to 24 than the HS females (-17%; P < 0.05). Moreover, a high mortality was registered for the LS females (7/29 vs. 0/29, in LS vs. HS respectively; P = 0.01). From day 25 to weaning, the feed intake of the litters was lower in the LS group than in the HS group (-13%; P < 0.05). Consequently, at weaning, the live weight of the LS rabbits was lower (-6%; P < 0.01). From days 18 to 32, mortality was higher in the LS group (5.2 vs. 0.8%; P < 0.01). After weaning, feed intake tended to be higher in the LS group, and on day 44, live weight did not differ between the groups. From days 32 to 44, morbidity tended (P = 0.06) to be lower for the LS rabbits. In conclusion, young rabbits would not regulate their feed intake according to the dietary DE level. Moreover, a feed change for females, at the lactation peak, reduced their intake level, leading to a lower milk production. This also induced a lower health status both in the females and in the liters.

The objective of the current work is to investigate the possible beneficial effects of forced feeding of fenugreek to rabbit does on their milk composition, milk yield, anemia screening parameters, immunity and the growth performance of bunnies. Twenty white New Zealand female rabbits were randomly assigned into 5 groups: normal control and 4 treated groups (vehicle (molasses), fenugreek powdered seeds + molasses, sprouted fenugreek + molasses, and fenugreek oil + molasses). All treated groups took the given doses orally for two days before parturition and 13 days after parturition for 2 successive pregnancies. Blood samples were collected from each doe on the 13 th day of lactation for determination of hematological, biochemical and immunological parameters. Milk samples were taken for evaluation of milk composition. All rabbit does and their bunnies were weighed for calculation of the milk yield. The fenugreek seeds and oil administered groups (G 3 & G 5 ) recorded the highest percent values of fat, protein, lactose, total solids and solid not fat contents of the rabbits' milk in both 1 st and 2 nd lactation periods relative to other tested groups. At the beginning and mid of lactation periods, the milk yields recorded non-significant differences either between tested groups or between 1 st and 2 nd pregnancy in the same group. Whereas, at the end of lactation, germinated seeds (G 4 ) and oil (G 5 ) treated groups recorded significantly higher rates of milk yield relative to control and fenugreek seeds groups. Bunnies' body weights suckling from dams of group III (G 3 ) recorded the highest weights relative to other tested groups in both 1 st and 2 nd pregnancy. During the 1 st lactation period, all experimental groups showed significant reduction of white blood cells, while, G 3 and G 4 recorded significant elevation during 2 nd lactation period. Rabbits treated with fenugreek seeds powder (G 3 ) showed a signifiHow to cite this paper: Abdel-Rahman, H., Fathalla, S.I., Assayed, M.E., Masoad, S.R. 1277cant raise of phagocytic activity and phagocytic index. Fenugreek seeds group (G 3 ) and germinated one (G 4 ) showed significant red blood corpuscles and packed cell volume raise relative to other groups during both 1 st and 2 nd lactation periods.
