“…Rebollar et al (2011) also found similar concentrations of leptin (2.8 ng/ml) and NEFA (0.22 mmol/l) in the blood of young females at 11 weeks of age when comparing ad libitum supply of control and fibre-rich diets. However, when higher feed restriction is asserted (even below animal needs 1.03 MJ/day; Rommers et al, 2004), the blood levels of glucose, leptin, insulin and T3 of young females (from 6 to 12 weeks of age) were clearly reduced.…”

“…-E-mail: jupascu@dca.upv.es For this reason, in the last decade, some works assessed the possible impacts of different management and feeding plans for the rearing period on female development and reproduction: feed restriction (Rommers et al, 2004), BW at weaning or at the first artificial insemination (AI; Rommers et al, 2001aRommers et al, , 2001bRommers et al, and 2002 or the use of fibrous diets (Xiccato et al, 1999;Pascual et al, 2002;Quevedo et al, 2005). However, some of these works have shown an antagonism between proper development and improvement of reproductive response.…”

“…However, some of these works have shown an antagonism between proper development and improvement of reproductive response. The earlier the introduction of the restriction programme and the lower the energy supply, the higher the voluntary feed intake of primiparous does with improved milk yield or reduced body reserves mobilisation during first lactation (Nizza et al, 1997;Xiccato et al, 1999;Pascual et al, 2002), but the later or the lower their pubertal maturation (Pascual et al, 2002;Rommers et al, 2004).…”

A total of 190 rabbit females were used to evaluate five feeding programmes from 9 weeks of age to the first parturition: CAL, fed ad libitum with a control diet (C: 11.0 MJ digestible energy (DE) and 114 g digestible protein (DP)/kg dry matter (DM)) until first parturition; CR, fed ad libitum with C diet until 12 weeks of age and then C diet restricted (140 g/day) until first parturition; F, fed ad libitum with a low-energy, high-fibre diet (F: 8.7 MJ DE and 88 g DP/kg DM) until first parturition; FC, fed with F diet ad libitum until 16 weeks of age, and C diet ad libitum until first parturition; FCF, fed with F diet ad libitum until 16 weeks of age, then C diet ad libitum until 20 weeks and then F diet ad libitum until first parturition. The rabbits were artificially inseminated at 18 weeks of age. CAL group had a higher mortality rate compared with the other groups between 9 and 12 weeks of age (34% v. 3%; P , 0.05) and during the last 3 weeks of first pregnancy (14% v. 3%; P , 0.05). The CAL and FC females presented higher BW and perirenal fat thickness (PFT) than CR females at 11 days of pregnancy (10.41 kg and 10.6 mm; P , 0.05), with F females showing medium values. The type of feeding procedure did not affect the fertility rate of young females at first artificial insemination. Differences in BW disappeared at parturition, when only CAL females presented a greater PFT than CR and FC females (10.3 mm; P , 0.05). In comparison with FCF, CAL females had smaller and thinner live born litters (22.5 kits and 2139 g, respectively; P , 0.05), with CR, F and FC females showing medium values. The low number of kits born alive for CAL females was because of their lesser total number of kits born (21.7 kits; P , 0.05) and the greater mortality of their litters at birth (113.9%; P , 0.05) compared with FCF females. Non-esterified fatty acid was higher in the blood of females fed C diet (CAL and CR) than in others at partum day (on average 10.15 mmol/l; P , 0.05). In conclusion, the ad libitum use of diets for lactating rabbit does throughout the rearing period could lead young rabbit females to present a higher risk of early death and smaller litter size at first parturition. Feed restriction or earlier use of suitably fibrous diets led females to achieve the critical BW and fat mass at first mating to ensure reproduction.

“…Gyovai et al (2004) observed higher body weight (at 1 st kindling and maintaining during the successive cycles) in does reared under feed restriction. In contrast, Rommers et al (2004) reported higher body weight in ad libitum reared does but their lower milk yield fall essentially on the very heavy young does (>4,5 kg at first insemination at 17.5 weeks of age), perhaps excessively fatty (Rommers, 2004). In earlier experiments, Coudert and Lebas (1985) did not observe any significant effect of feed restriction during rearing on does LW measured 7 days after the kindling in the 3 first lactations.…”

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.

“…There is also a considerable fatty deposition in the liver so intense that it may interfere with the liver function (Bruss, 1997). Episodes of pregnancy toxaemia can be surmised in rabbit does, which lead females to higher mobilization of reserves in late pregnancy (Rommers et al, 2004;Martínez-Paredes et al, 2012). Subsequently, body reserves are recovered during the first stage of lactation and reach a maximum around day 10 in lactation (Quevedo et al, 2007).…”

The aim of this study was to investigate the metabolic and biochemical changes in plasma that occur in the reproductive rabbit doe close to the parturition, as well as if the number of offspring affects the metabolism and the health status of the doe. At − 3, 4 and 12 days from parturition (-D3, D4, and D12, respectively) nine rabbit does at their third parity from a commercial hybrid line (HYPLUS PS 19) selected for high prolificacy were weighted and blood was collected for a wide inflammometabolic profile. According to the number of offspring the does were retrospectively divided in two groups: high litter size group (HI; n = 5) and low litter size group (LO; n = 4). BW was higher (P < 0.01) at -D3 and had the lowest values at D4. At D12, the BW was lower (P < 0.05) in LO compared with HI. Several metabolites significantly changed from dry to lactation period. Glucose and cholesterol had the lowest levels at -D3; non-esterified fatty acid (NEFA) and aspartate aminotransferase had the highest values before parturition (P < 0.05); creatinine and β-hydroxybutyrate (BHBA) were higher at -D3 with respect to D4 (P < 0.05). The lowest value of paraoxonase was observed in does at -D3 (P < 0.05), whereas at this time ceruloplasmin and total bilirubin had the highest concentration (P < 0.05). The differences for blood profile parameters between does grouped according to litter size were mainly evident before parturition (-D3). In particular, BHBA, NEFA and total bilirubin had higher concentrations (P < 0.05) in HI v. LO group, whereas albumin and PON were lower in HI group (P < 0.01). After parturition there were no significant differences for the metabolic parameters between the two groups. The results show that for reproductive rabbit doe the last days of gestation are very stressful from a metabolic and inflammatory point of view. The genetic selection of does for higher litter size has increased their ability to mobilize body reserves in order to guarantee the nutrients to a high number of kits. This exposes them to a more severe metabolic and inflammatory challenge during the transition period. Consequently, feeding and managerial strategies for high prolificacy periparturient rabbit does should be revised.
