“…Studies performed at INRA (Lebas et al, 1973;Colin 1974, 1975 a and and those of Davison and Spreadbury (1975) and Spreadbury (1978) led to confirming the essentiality of these amino acids and the high requirements of arginine, in contrast to the ones observed in poultry. They also suggested that the optimal level of an amino acid depends on the balance with other amino acids and the level of energy in the diet, so the recommendation for lysine is given in grams per 1000 kcal of digestible energy.…”

ABSTRACT:In the European context, the new legislation to avoid mineral contamination and the ban on antibiotics as growth promoters has led to the defi nition of new objectives in respect of nitrogen supply. The present study summarizes the state of nitrogen nutrition in rabbits and reviews the role of protein and amino acids in rabbit health and the new nitrogen value of protein sources based on true ileal digestibility (TID) for future recommendations. The main sources of nitrogen for microbial growth are ammonia, urea and protein (endogenous and dietary). The surplus of nitrogen fl ow to the caecum increases mortality rates during fattening by favouring the growth of potential pathogenic bacteria. Accordingly, feeding strategies to reduce ileal nitrogen fl ow have been reviewed. A large reduction of dietary protein level might have negative consequences on growth performances and mortality. In order to formulate balanced lowprotein diets, data on ileal and faecal amino acid digestibility of 14 raw materials is summarized. The use of this different unit for amino acid digestibility is also discussed.

“…Studies to determine the required levels of amino acids for rabbits began in the 1960s (McWard et al, 1967;Gaman & Fisher, 1970;Cheeke, 1971;Adamson & Fisher, 1971, with those focusing on commercial animals starting in the 1970s (Lebas et al, 1973;Colin, 1975;Davison & Spreadbury 1975;Spreadbury, 1978) and forming the basis of the nutritional recommendations included in the NRC (NRC, 1977).…”

-Two experiments were carried out to evaluate, respectively, nitrogen balance (NB) and the productive performance of 31-to-50-day-old rabbits subjected to different levels of lysine and methionine+cystine (met+cys). Seventy-five animals were randomly distributed in 5 × 3 blocks (five levels of lysine: 5.5, 6.5, 7.5, 8.5 and 9.5 g/kg combined with three levels of met+cys: 5.0, 6.0 and 7.0 g/kg), with 15 treatments and five replications for the NB assay. The assay lasted 14 days: 10 days for acclimatization and four days for feces and urine collection. Increasing met+cys levels had a quadratic effect on the nitrogen excreted in urine (NU): the lowest excretion was found at the dietary level of 5.9 g/kg met+cys. Increasing lysine levels also affected NU and nitrogen retained daily (NR): the lowest NU was obtained at the dietary level of 7.28 g/kg lysine, and maximum NR was found at 7.24 g/kg lysine. Increases in met+cys levels in the diets affected neither performance nor carcass characteristics of rabbits up to 50 days of age. On the other hand, body weight at 50 days, daily weight gain and feed conversion of rabbits slaughtered at 50 days had a quadratic effect as the lysine levels increased. The best results were found at 7.5, 7.38 and 7.36 g/kg lysine. Lysine and met+cys levels of 7.4 and 5.0 g/kg in the diet are recommended for 31-to-50-day-old rabbits.

“…For example, in controlled experimental conditions, a diet containing only 60 g fibre kg −1 dry matter (DM, as acid detergent fibre, ADF) may not induce digestive trouble ( Davidson and Spreadbury, 1975). A similar situation has been observed with diets containing up to 280-300 g crude protein (CP) kg −1 (Lebas, 1973). However, in rabbit-farming conditions, such imbalances lead to a high risk of digestive disorders, and obviously must never be recommended for practical feeding.…”

Nutrition of the Rabbit

This chapter discussed the health problems (mainly digestive) linked to the balance of dietary components and the presence of nutrients in excess, mainly in relation to the initial composition of feed ingredients, but also to the feeding strategy. Also highlighted are the feeding strategies (feed quantity and nutritional quality) for the doe and for the growing rabbit. The last section will cover the health consequences of non-nutritional components that are frequently associated with feed ingredients, such as mycotoxins and water quality. The methods for health status assessment that are practical in rabbit breeding were also discussed.
