“…On the other hand, Hullar et al (1996) obtained improvements in rabbits' performance after adding sodium butyrate to the diet for 4 wk. Dissenting results have also appeared with the addition of other acids: fumaric acid led to a improvement in the performance parameters of growing and fattening rabbits although not statistically significant (Scapinello et al, 2001;Michelan et al, 2002) and formic acid together with lactic acid improved the feed efficiency and average daily weight gain in 30-55 and 56-84 d old rabbits (Cesari et al, 2008).…”

AbstrAct:To study the effect of adding coated sodium butyrate (SB) to growing-fattening rabbit diets, 2 trials were conducted. In trial 1, 180 rabbits were housed in pairs and fattened from 23 (weaning) to 63 d of age to evaluate their zootechnical performance. Trial 2 involved 30 rabbits, from 23 to 37 d of age and housed individually in digestibility cages, to evaluate digestibility, caecal fermentative activity and morphology of the intestinal mucosa. In both trials rabbits were randomly divided into 2 groups, each receiving one of the following diets: control diet [CTR, 360 g neutral detergent fibre (NDF) and 170 g crude protein (CP)/kg dry matter (DM)] and SB diet. The SB diet, similar to CTR diet, included coated SB at 5 g/kg by replacement of an identical quantity of wheat. In trial 1, after the first 2 wk, the SB content was reduced from 5 to 3 g/kg. In trial 2, faeces were collected over the last 6 d (32-37 d of age), with rabbits being slaughtered at 37 d of age. Gastric and caecal pH were measured and fermentative activity was determined in caecal contents. Three sections of the small intestine were excised from 20 rabbits (10 per treatment) for microscopic examination of intestinal villi and crypts in the proximal region, central region and distal region. In the first 2 wk after weaning, SB rabbits grew 8% less than their counterparts (P=0.002), but had a better feed conversion ratio (1.58 vs. 1.61; P=0.036). During the whole trial 1 period, SB improved feed conversion (P=0.005) and decreased feed intake (104.1 CTR vs. 98.8 g/d SB; P=0.017). No difference was recorded in daily weight gain (42.7 vs. 42.9 g/d). In both diets, the digestibility of DM, organic matter, energy, CP and NDF were similar. In the 3 intestinal regions of rabbits fed SB diet, crypts were deeper (P<0.05). There were no significant differences in villus height and width between treatments. Pectinase activity was higher (P=0.054) with SB diet, but cellulase and xylanase activity remained unaffected by diet. In our experimental conditions, the addition of SB allowed an improvement in feed conversion.

“…Recently, Brazilian researchers (Scapinello et al, 2001;Michelan et al, 2002) found that the inclusion of 1,5% of fumaric acid in the feeds of growing rabbits tended to improve both the daily gain and the feed efficiency, but the differences were not statistically significant. Similar results were reported by Hollister et al (1990) (Table 5).…”

“…Combining organic acids with prebiotics (Scapinello et al, 2001) or with probiotics (Michelan et al, 2002) did not significantly improve performances, though mortality was significantly reduced in one trial (Hollister et al, 1990) where fumaric acid was combined with Lacto-Sacc.…”

This review is focused on the most studied and developed substances which are commonly known as alternatives to dietary antibiotics, particularly as far as rabbit feeds are concerned. After a reminder of the reason to be and success of antibiotic growth promoters, and why they lately came to be banned in the European Union, we successively deal with probiotics, prebiotics, enzymes and organic acids. Data on rabbits are, as expected, quite scarce when compared to species such as pigs and poultry. Nevertheless, the available performance results are discussed together with the possible mechanisms of action. Special mention is made of the effects of these substances on digestibility and caecal activity.

“…Contudo, ainda não é conhecida à composição microbiana ideal de um produto probiótico, mas a eficiência do seu uso é estritamente dependente da quantidade e das características das cepas bacterianas utilizadas na elaboração do aditivo alimentar SCAPINELLO et al, 2001). Os mananoligossacarídeos são derivados da parede celular interna de leveduras e seu modo de ação é ligando-se a certas bactérias patogênicas no ambiente gastrintestinal, essas bactérias ligadas aos oligossacarídeos não podem aderir à infecção iniciada no intestino (DE ARAÚJO et al, 2007), também auxiliam na preparação do sistema imune para combate de infecção (SCAPINELLO et al, 2001).…”

ResumoO avanço da aqüicultura e a crescente demanda por alimentos de origem animal, aliado à preocupação com a segurança alimentar dos consumidores, vêm fazendo com que se aumentem os cuidados com a produção animal, contaminação do ambiente e suas complicações. Com isso, esta revisão foi realizada com o objetivo de debater os principais fundamentos da utilização de aditivos na nutrição de peixes. Pesquisas estão sendo desenvolvidas neste sentido nas diferentes espécies animais com resultados satisfatórios em todas as fases dos ciclos de produção. Este trabalho apresenta os resultados alcançados pelo uso de aditivos alimentares na produção de peixes quanto ás características de desempenho e saúde. Palavras chave:Aqüicultura, desempenho zootécnico, higidez, micro ingredientes, promotores de crescimento. Key words:Aquaculture, animal performance, health, micro ingredients, growth promoters AbstractThe progress of aquaculture and the growing demand for food of animal origin, coupled with concern about food safety for consumers, are causing it to increase the care of animal production, environmental contamination and its complications.
