“…The chemical composition of whole maize plant utilized in this research is similar to that reported by Mader et al (1983), Tolera and Sundstol (2001) and Michalet-Doreau et al (2004). The whole maize plant is a forage with a moderate content of fibres and low content of CP (from 4 to 13% DM) and acid detergent lignin (from 1.0 and 7.4% DM) (Dardenne et al, 2005).…”

“…Due to its high humidity, whole maize plant requires to be dehydrated before inclusion in pelleted diets for rabbits and the maturity stage is important, since the dry matter (DM) content of maize plant increases from 23 to 37% during the maturing process of the grain (Abreu et al, 2000). In general, immature maize has a higher protein concentration than mature maize (Tolera and Sundstol, 2001;Michalet-Doreau et al, 2004), but a lower energy value. As grain progresses from early dough stage to commercial maturity, the percentage of grain in the plant increases, and consequently crude protein (CP) and crude fibre (CF) decrease while starch increases (Mader et al, 1983).…”

Seven diets were formulated in order to determine the nutritive value of whole maize plant at three stages of maturity by substitution of a control diet (C) with 20% and 40% whole maize plant at early dough, mid-dent and mature stages of grain. A digestibility trial was performed with 74 rabbits. Digestible protein and energy values of whole maize plant at different maturity stages were calculated by substitution and regression procedures. A fattening experiment was carried out with 200 rabbits from weaning (28 days of age) giving ad libitum either diet C or 20% mature whole maize plant. One hundred and forty-three rabbits were slaughtered at 63 days of age and some carcass traits were measured.The crude protein and fibre content of whole maize plant decreases as the kernel matures (CP: 8.3, 8.1 and 7.6% DM; CF: 15.8, 12.6 and 13.4% DM; NDF: 45.3, 38.0 and 38.0% DM; ADF: 19.1, 15.0 and 16.1% DM for early dough, mid-dent and mature stages, respectively). The digestible energy concentration, calculated by regression, of whole maize plant increased (P<0.01) with maturity stage (8.5, 9.5 and 10.4 MJ/kg DM, respectively) but the digestible protein value was higher (P<0.01) at the intermediate maturity stage (3.7, 4.5 and 3.2% DM). Rabbits given the diet with 20% plant maize at the maturity stage had similar feed intake (101 vs. 99 g DM/d) and live weight gain (44 vs. 45 g/d) but a worse feed conversion index than C rabbits (2.29 vs. 2.21, P=0.03). No differences were found at slaughter in live weight, carcass characteristics and dressing percentage of rabbits fed the two experimental diets.

“…This is consistent with reports suggesting that legumes and other protein-rich forages have a great potential to improve the utilization of poor quality tropical grasses and crop residues (Preston & Leng, 1987;Nsahlai et al,1998;Norton & Waterfall, 2000). The degradation characteristics of desmodium and sweet potato vine were similar, but recent studies have shown that the moderate levels of tannins (2-4%) contained in Desmodium intortum can exert beneficial effects on protein metabolism by increasing the proportion of bypass protein (Aerts et al, 1999;Tolera & Sundst l, 2001). Although the presence or absence of anti-nutritional factors in sweet potato vine has not been established (Woolfe, 1990), higher rumen NH3-N concentrations were observed with sweet potato vine supplemented diets than with desmodium supplemented diets, a probable reflection of a more rapid degradation.…”

This study was conducted to assess the effect of greenleaf desmodium (Desmodium intortum) and sweet potato vine (Ipomoea batatus) supplementation of napier grass on dry matter intake, degradation and rumen fermentation in Friesian steers. Four fistulated steers were offered napier grass diets containing 0, 10, 20 or 30% desmodium or sweet potato vine in two 4 x 4 latin squares. Organic matter intake per kg metabolic body weight increased linearly with increasing inclusion level of desmodium (74-90 g/ kg 0.75) and sweet potato vine (78-94 g/kg 0.75). Crude protein intake also increased linearly with the increase in inclusion level of desmodium (7.6-13.0 g/kg 0.75) and sweet potato vine (7.9-12.9 g/kg 0.75). Supplementation improved DM degradation but did not change rumen pH. Rumen fermentable organic matter increased by up to 52% and 43% for desmodium and sweet potato vine respectively at the highest levels of supplementation. Ammonia nitrogen concentrations increased with increasing level of desmodium (130-214 mg/l) and sweet potato vine (139-235 mg/l). Inclusion of desmodium and sweet potato vine led to small increases in concentrations of total and individual volatile fatty acids. It was concluded that the two forage supplements could play an important role in improving animal performance when napier grass is fed as the basal diet.

“…However, maize silage as a livestock feed has a low CP concentration, 8-9% (Carruthers et al, 2000;Darby and Lauer 2002) and 8.1% according to Feedipedia for the silage, with less than 25% DM. Protein content decreases with the maturing process (Tolera and Sunstol, 2001;Michalet-Doreau et al, 2004).…”

Specific knowledge of the nutritive value of raw materials is fundamental to formulate balanced diets for rabbits and allows greater use of by-products and non-conventional feedstuffs. This paper examines the feeding value of sun-dried brewers' grain and maize silage (whole plant) for fattening rabbits. Twentyfour individually caged 8-wk-old rabbits were used to determine the digestibility. Both wet products were sun-dried and ground before being incorporated into a basal diet. The inclusion level at the expense of all basal ingredients amounted to 30%. Basal diet and both experimental diets were fed ad libitum to 8 rabbits during the 4-d balance trial. The determined digestibility of protein, fat, crude fibre and neutral detergent fibre digestibility amounted to 76.2 and 77.2%; 86.5 and 99.1%; 8.1 and 8.3% and 28.0 and 13.5%, respectively, for brewers' grain and maize silage. The digestible energy content amounted to 11.66 MJ/kg dry matter (DM) (brewers' grain) and 11.10 MJ/kg DM (maize silage). Both by-products have potential as alternative feedstuff in rabbit diets. However, further experiments are necessary to determine the effect of ensilaging the whole maize plant, as a significantly lower (P<0.001) feed intake was observed.
