“…The antimethanogenic effect observed for diets containing FB, which increased with the FB levels in the diet, was in agreement with Johnson and Johnson (1995) who observed in vivo a reduction in methane production with increased substitution of concentrate in diet. The results obtained in the present work are in line with those obtained when barley grain was replaced with citrus pulp, a byproduct with low starch content (Ben-Ghedalia et al, 1989).The increased antimethanogenic effect observed as the amount of tomato and cucumber by-products increased in the diet could be due, to some extent, to tannins present in the studied byproducts. Secondary plant compounds have been shown to modify rumen fermentation, inhibiting enteric methanogenesis, although their mechanisms of action still are not well understood (Patra and Saxena, 2010).…”

“…These values are lower than those reported by Ben-Ghedalia et al [3] in two-year old Merino rams fed two diets with 84.4% and 20.4% of citrus pulp and rationed lucerne hay. Our values are probably due to the lack of structured fibre in the diets because of the high grinding level of feeds analysis did not show any significant difference between treatments.…”

Replacement of cereal grains by orange pulp and carob pulp in faba bean-based diets fed to lambs: effects on growth performance and meat quality

-Fourteen weaned lambs (43 days of age) were divided into two equal groups of seven animals and received two different diets. The experimental diet contained 10% of carob pulp and 10% of orange pulp associated to 54% of faba bean. The control diet contained 12% of maize meal and 12% of barley meal associated to 49.2% of faba bean. Both diets were pelletted and given ad libitum. The two diets had comparable contents of dry matter, ash, crude fat, fibre and crude protein. Control diet was relatively higher in soluble nitrogen than the experimental one. However, experimental diet was higher in fibre-bound nitrogen and in total and condensed tannins than control one. At the end of the feeding trial (120 d of age) growth and slaughter performance were comparable between treatments. Chemical analysis of meat samples did not show any significant difference between groups. Physical analysis of meat showed a higher (P < 0.05) lightness (L*) value in experimental group than in the control one. Sensory analysis allowed the panellists to discriminate lamb meat from the two groups. Flavour, tenderness and juiciness were judged to be more intense (P < 0.01) in the meat of control group; also overall acceptability was higher (P < 0.05) in this group. It was concluded that the replacement of cereal grains with carob and orange pulp in lamb fattening diet is useful to reduce feeding costs. Nevertheless, we need further investigations on the level of inclusion in the diet, in order to avoid the negative effects on sensory attributes without detrimental effect on growth performance.cereal grains / orange pulp / carob pulp / growth / meat quality / sheep Résumé -Remplacement des grains de céréales par la pulpe d'orange et la pulpe de caroube dans des régimes à base de féverole destinés aux agneaux.

“…Schaibly and Wing [31] reported that rations with citrus pulp increased the molar percent acetic acid. Ben-Ghedalia et al [3] replaced barley with citrus pulp in diets for sheep and observed greater acetate: propionate ratios in the ruminal fluid of the sheep fed the citrus pulp. This effect may be explained by the higher pectin content of citrus by-products.…”

-The samples used in the experiment were nine types of by-products: giant pumpkin, red pepper, melon, broccoli, brewer's grains, fresh and boiled artichoke, lemon peel and orange peel. The dry matter degradability of each by-product was determined by in vitro fermentation with ruminal fluid of the goat. The materials were incubated at 39 ºC for 12, 24, 48 and 72 h. At each time, pH, dry matter disappearance, neutral-detergent fibre disappearance, volatile fatty acids, lactic acid and ammonia productions were measured. Approximately 50% of the total dry matter loss of broccoli, melon and peels occurred at 12 h incubation. In addition, the total dry matter loss of the giant pumpkin, fresh and boiled artichoke, and brewer's grains was low (< 50% of dry matter loss) at 12 h. The molar proportion of acetate and propionate was influenced by the type of the feedstuffs. Thus, the acetate proportion was > 70% for all by-products, except for brewer's grains (63.8%), and the propionate proportion was < 20% for all by-products, except for the brewer's grains (21.3%). In conclusion, the ruminal dry matter and cell wall degradations, and production of fermentation end-products by in vitro determination offers a convenient method to compare the microbial digestion of the different byproducts.in vitro fermentation / dry matter degradation / cell wall degradation / by-product Résumé -Détermination de la dégradation ruminale in vitro, de la matière sèche, de la paroi cellulaire, et de la production des produits finaux de fermentation de divers sous-produits. L'expérience a porté sur 9 types de sous-produits : citrouille, poivron, melon, brocoli, drèche de brasserie, artichaut cru ou bouilli, zeste de citron, et zeste d'orange. La dégradation de la matière sèche de chaque sous-produit a été déterminée par la fermentation in vitro dans du liquide ruminal de chèvre. Les échantillons ont été maintenus à 39 ºC pendant 12, 24, 48 et 72 heures. A tous ces temps, le pH, la disparition de la matière sèche, la disparition du NDF, les acides gras volatils, l'acide lactique et l'ammoniac ont été mesurés. Environ 50 % du total des pertes de matière sèche du brocoli, du melon et des zestes ont eu lieu après 12 heures d'incubation.
