Colonisation of the caecum by Bacteroides commenced already on day 3 after birth. On day 2 the bacteroides counts were below 100, while on day 4 they were already between 100 and 10000. In Group CN, the Bacteroides counts were lower ( by 14 to 40%) throughout the 10-day period studied than in the groups having access to maternal faeces. Differences between groups were significant only on days 4 and 6. The average number of maternal faecal pellets left behind the doe in Group CN was 3-4 ( between 0.5 and 6.4 per doe). In Groups FF and CF the pellets became smaller, crumbled and finally disappeared from the nest box, they were consumed by the pups and could be found in their gastric content. The lactobacillus counts decreased in all three groups with age, from 6.0 to 3.5 log10 CFU center dot g(-1) ( FF), 4.6 to 2.8 log10 CFU center dot g(-1) ( CF) and 5.1 to 3.1 log10 CFU center dot g(-1) ( CN), respectively. The coliform counts were higher in the first 4 days in FF ( 5.6 log10 CFU center dot g(-1)) than in CF (< 2 log10 CFU center dot g(-1)) and CN ( 2-3.6 log10 CFU center dot g(-1)) animals. Bacteroides could be cultured from the surface of the vulvar labia ( max. 1000 colony count) and the vagina ( max. 190 colony count), so young rabbits could become "infected" by them already in the doe's vagina. Thus prevention of ingestion of maternal faeces only slightly influenced the development of the bacteroides flora, the faeces left behind by the doe did not play an exclusive role in their colonisation.

A review of quantity, quality and non-dietary affecting factors TS - A review of quantity, quality and non-dietary affecting factors JF - WORLD RABBIT SCIENCE J2 - WORLD RABBIT SCI VL - 14 PY - 2006 IS - 4 SP - 205 EP - 230 PG - 26 SN - 1257-5011 DO - 10.4995/wrs.2006.565 UR - https://m2.mtmt.hu/api/publication/1250374 ID - 1250374 AB - 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 x 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 degrees 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 omega-6/omega-3 ratio around 4. Finally some data about the amino acid, milk proteins including the immmunoglobulins, mineral and vitamin composition are presented.

Control litters (SS) were nursed once a day for 35 days post partum (traditional method of nursing). DD litters were raised by two does and the kits were nursed both in the morning and in the evening until day 35 post partum. DS litters were nursed twice a day for 23 days, and then once a day until weaning at 35 days. Part of the DS litters were nursed at 08:00 and 20:00 h (i.e. every 12 h, DS12), the rest were nursed at 08:00 and at 16:00 h (DS8). Kits of the fifth treatment (DO) were nursed twice a day until day 23, and then immediately weaned. Rabbit kits that were nursed twice a day (DD, DS12, DS8, DO) consumed on average 1.89 more milk compared with SS individuals until day 23 (overall treatment effect P < 0.001). The 21-day body weight of these young was 1.7 times greater than that of the SS kits (overall P < 0.001). DO rabbits were weaned early and their growth curve showed a slight break at this point. However, they compensated for this lag by the end of the fattening period. SS rabbits and DD ones were respectively the first and the last to start consuming solid food. The food consumption of DS rabbits was similar to that of DD until day 23 and from then until day 35 it was not significantly different from that of SS. After having been weaned on day 23, DO kits consumed only very small quantities of pellets for 2 days. Afterwards their food intake increased abruptly. Rabbits that were nursed twice a day (DD, DS12, DS8 and DO) consumed more food as compared with the SS individuals throughout the total period of fattening (157 v. 137 g/day; P < 0.05). The weight at 10 weeks of age was 2.49 v. 2.88 kg (overall P < 0.001), respectively for SS and double-nursed (DD, DS, DO) rabbits. Nursing twice a day did not affect dressing proportion but the proportion of the carcass in the front part of the body decreased slightly (318 v. 323 g/kg; P < 0.05) while that in intermediate part increased (321 v. 307 g/kg, P < 0.05). Nevertheless, rabbits that were nursed twice a day had more (P < 0.05) perirenal + scapular fat and produced heavier livers. Total fat content of the empty body, however, was not significantly higher, with the one exception of the DD rabbits which had higher levels than any other group. The results of our experiment show clearly that the growth potential of rabbit kits is strongly limited by the milk availability during the first weeks post partum.

At the age of 23, 30, 37 and 44 days, 8 young per treatment were euthanised. Double suckling and the subsequent higher level of solid feed intake after weaning were found to exert a stronger influence on the weight of the entire gastrointestinal tract and that of its individual parts (the stomach, small intestine, caecum and colon) than on its length. The quantity of the gastric content was found to rise with advancing age in both groups (from 36 to 70 g and from 37.5 to 79 g). In both groups the pH of the stomach was higher during the suckling period (4.5-5.3) than subsequent to weaning (1.6-2.4). The quantity of the caecal content also increased with age (from 4 or 8 g), but on the 37th day significantly higher quantities of caecal content were recorded in DD rabbits (50.5 g compared with 35 g). The pH of the caecal content decreased more slowly from an initial high value (6.0 and 6.5 in SS and DD rabbits, respectively), and by the 37th day had settled at a low value (5.7-5.8) in both groups. The dry matter content of the caecal content decreased from 270-273 g to 188-207 g in both groups. Total volatile fatty acid (tVFA) and acetic acid (C2) concentration, which amounted to 66-88% of tVFA, rose; in SS rabbits they were at higher levels by the 30th day (53.6 and 42.2 mmol/L, respectively), and remained at an increased level until the 44th day (P < 0.05). The ratio of C3: C4 was high on the 23rd day (2.5 and 2.4), but dropped at the age of 30 days (0.5 in SS and 1.7 in DD, P < 0.05) and, further, by the 37th day (0.2 in SS). In SS rabbits coliform count proved significantly lower (105) on the 23rd day than in DD rabbits (106). By the 37th day this count had decreased in both groups and subsequently remained at a low level (<10(4)). By the 23rd day Bacteroides were present in large quantities (10(8)) in the caecum and showed no change with advancing age or feeding regime.
