“…Overall, these measurements support a theory of longer retention time of digesta in the caecum of restricted rabbits observed by Ledin (1984a and1984b) and . Whatever feed restriction, age or the group × age interaction, the caecal levels of total VFA or the VFA molar proportions were within the range of the values reported by Gidenne (1997) and García et al (2002). The VFA molar proportions differ significantly according to age, which is probably associated with the relationships among ages, intestinal microflora and fermentation parameter (Padilha et al, 1995).…”

A 3 to 4 week feed restriction of about 20% to 25% of the free intake is widely applied in rabbit breeding systems to reduce postweaning digestive disorders. However, a short intensive feed restriction is described in few studies and can be beneficial for growing rabbits due to a longer re-alimentation period. The aim of this study was to evaluate the effect of ad libitum (AL) and two restriction levels of feeding (50 and 65 g/rabbit per day) applied for 1 week on performance, gastrointestinal morphology and physiological parameters during the restriction and during the re-alimentation period. Rabbits were divided into three experimental groups: AL rabbits were fed AL, R1 rabbits were restricted from 42 to 49 days of age and received 50 g daily (29% of AL) and R2 rabbits were restricted at the same age and were fed 65 g of feed daily (37% of AL). In the 1 st week after weaning and in the weeks after restriction, all the groups were fed AL. During the restriction period, daily weight gain (DWG) in R1 significantly dropped to 11% (experiment 1) and 5% (experiment 2) compared with rabbits in the AL group, although they were fed 29% of AL, whereas in the R2 group it decreased to 20% (experiment 1) and 10% (experiment 2). In the week following feed restriction, DWG in the restricted groups increased (P < 0.001) to 166% and 148% in R1 and to 128% and 145% in R2. Restricted rabbits in both the experiments reached up to 90% to 93% of the final live weight (70 days) of the AL group. Over the entire experimental period, feed restriction significantly decreased feed intake to 85% to 88% of the AL group; however, the feed conversion ratio was lower (P < 0.05) only in experiment 1 (−6% in R1 and −4% in R2). Digestibilities of CP and fat were not significantly higher during the restriction period and during the 1 st week of re-alimentation compared with the AL group. Significant interactions between feeding regime and age revealed the shortest large intestine in the AL group at 49 days of age and the longest at 70 days in the AL and R1 groups. Small intestinal villi were significantly higher and the crypts were significantly deeper in the restricted groups. It could be concluded that short intensive feed restriction increased digestible area in the small and large intestines, including the height of villi and depth of crypts, which might be involved in the compensatory growth and defence mechanism.

“…It is hypothesised that glucosinolate may not have a deleterious effect on nitrogen utilisation. Anti-nutritional factors such as resistant fibre, lignin and tannins supply have been implicated to influence intestinal characteristics and activity of the caecal ecosystem (Blas et al, 1994;De Blas et al,1999;Gidenne, 1997;Bennegadi et al, 2001). MM incorporation did not affect empty caecum weight, total caecum weight and intestine weight as per cent of LW, showing that the fibre quality of MM was as good as SBM.…”

Effect of graded levels of high-glucosinolate mustard (Brassica juncea) meal as substitute of soya-bean meal (SBM) in broiler rabbit diets was studied. Forty weaning rabbits of Soviet Chinchilla and White Giant breed were randomly allocated to one of four experimental diets containing mustard meal (MM) 0, 80, 160 and 245 g/kg. The experiment lasted for 8 weeks. MM had 54.8 mg total glucosinolates (TGLSs) per g dry matter (DM). Diets had TGLS 3.8, 8.4 and 11.98 mg/g DM in 80, 160 and 245 g MM diets, respectively. MM-incorporated diets had higher digestible and linearly (P , 0.01) higher metabolisable energy (ME) content. However, the effect on total tract apparent digestibility of DM, and crude protein was quadratic. Average daily gain (ADG) reduced (P , 0.05) linearly with increasing MM levels in diet, still 80 and 160 g MM diets had similar ADG compared to that of SBM diet. Caecum weight reduced linearly (P , 0.05) with increasing MM levels in diet. The pH of caecal content ranged between 5.85 and 6.19, total N between 1.19 and 1.48 (g per 100 g) and total volatile fatty acids between 4.7 and 5.8 mmol per 100 g, and they were not statistically different. NH 3 -N ranged between 31.2 and 39.0 mg per 100 ml, and reduced linearly (P , 0.05) while trichloroacetic acidprecipitable nitrogen increased linearly (P , 0.01, ranged between 114 and 247 mg per 100 ml) with increasing MM levels in diet. Blood haemoglobin, packed cell volume and lymphocytes were higher (quadratic effects, P , 0.05) on 245 MM diet, whereas white blood cell count reduced linearly (P , 0.01). Serum aspartate aminotransferase increased linearly (P , 0.01) while alanine aminotransferase and alkaline phosphatase activity, protein, erythrocytes sedimentation rate and red blood cell counts were not affected by MM. Serum Cu, Na and K content increased linearly (P , 0.05) with increasing MM levels. Liver Cu concentration showed quadratic (P , 0.05) increase. Rabbits tolerated 8.4 mg TGLS per g diet (160 g MM per kg) during active growth without any apparent effect on health and growth. It is concluded that MM can replace up to 66% SBM protein in rabbit feeding, whereas complete replacement of SBM with MM reduced feed intake and ADG by 23% and 13%, respectively. Further studies are required to confirm these inclusion levels and glucosinolate tolerance of rabbits.

“…Os níveis elevados de amido na dieta de coelhos recém-desmamados podem causar disfunções digestivas graves, as quais podem levar o animal à morte, visto que a atividade enzimática específica para a sua digestão, a amilase, ainda está imatura (Gidenne, 1997). Na tentativa de reduzir a quantidade desse ingrediente na dieta de coelhos jovens, óleos ou gorduras são adicionados.…”

 RESUMODois experimentos foram conduzidos com o objetivo de determinar a energia digestível da glicerina semipurificada vegetal e mista e o desempenho de coelhos em crescimento alimentados com dietas contendo os coprodutos. No ensaio de digestibilidade, foram utilizados 108 coelhos da raça Nova Zelândia Branco, com 45 dias de idade, distribuídos ao acaso em nove tratamentos (0, 4, 8, 12 e 16% de inclusão de glicerina vegetal e mista na dieta), com 12 repetições. Para o ensaio de desempenho, utilizaram-se 180 coelhos da raça Nova Zelândia Branco, dos 32 aos 70 dias de idade, distribuídos ao acaso em arranjo fatorial 2 x 4 (dois tipos de glicerina e quatro porcentagens de inclusão: 3, 6, 9 e 12%) mais uma dieta referência, com 10 repetições e dois animais por unidade experimental. Glicerinas vegetal e mista apresentaram energia digestível de 4.048 e 3.697kcal/kg MS, respectivamente. Entre 32 e 50 dias de idade dos coelhos, a dieta com 12% de glicerina mista prejudicou (P<0,05) o ganho de peso (32,14 g/dia), a conversão alimentar (3,57) e o custo por quilo de ganho de peso (R$ 2,08) em relação à dieta referência (39,42g/dia, 2,87 e R$1,69, respectivamente). Dos 32 aos 70 dias, o ganho de peso (30,11g/dia) e a conversão alimentar (3,99) dos animais que receberam 12% de glicerina mista na dieta foram piores (P<0,05) em relação aos da dieta referência (34,00g/dia e 3,65, respectivamente). Para as características de desempenho, dos 32 aos 70 dias, não foram verificadas diferenças (P>0,05) entre a inclusão de glicerina vegetal na dieta e a dieta referência, porém a maior viabilidade econômica (P<0,05) foi com 12% de inclusão (R$1,89 x R$2,15, respectivamente). A glicerina vegetal pode ser incluída em até 12% da dieta e a mista, em até 9%, diminuindo o custo de produção sem afetar o desempenho animal.Palavras-chave: coelho, conversão alimentar, custo, ganho de peso, transesterificação catalítica (0, 4, 8, 12 and 16% of (39.42g/day, 2.87 and R$ 1.69, respectively). From 32 to 70 days, weight gain (30.11g/day) and feed conversion (3.99) of the animals fed with the diet containing 12% of mixed glycerin were worst (P<0.05) in relation to the reference diet (34.00 g/day and 3.65, respectively). ABSTRACT Two trials were conducted with the goal of determining the digestible energy of vegetal and mixed semi purified glycerin and the performance of growing rabbits fed with diets containing the byproducts. In the digestibility assay 108 New Zealand White rabbits, 45 days old, were used, assigned in a completely randomized design into nine treatments
