“…Arthur (1995) indicated that DBM bulls have reduced DMI compared with other cattle because of the small size of their gastrointestinal tracts. The low DMI combined with the increased muscle mass of DBM may lead to greater CP requirements (Fiems et al, 1990;Arthur, 1995). The current work is one of the few reporting DMI data of DBM Piemontese bulls fed corn grain and corn silage diets.…”

“…In the intensive farms in Italy, cereals and corn silage-based diets with 140 to 150 g/kg of DM of protein density are commonly applied (single-phase feeding) to cattle of conventional breeds (Cozzi, 2007); similarly, in the United States, Galyean (1996) found that CP densities ranging from 125 to 144 g/kg of DM are commonly used in the feedlot cattle industry for finishing beef cattle. The increased potential for lean growth and the moderate feed intake capability have suggested that diets with energy and protein densities greater than those applied on conventional cattle should be used for DBM bulls (Fiems et al, 1990). For DBM Belgian Blue bulls, Boucqué et al (1984) indicated that ration CP density should exceed 140 g/kg of DM, whereas a content of 120 g/kg was found to be sufficient for non-DBM Belgian Blue bulls.…”

“…Compared with other cattle, DBM animals have less bone, less fat, more muscle, a greater dressing percentage (Shahin and Berg, 1985), and likely a reduced intake (Trillat, 1967;Vissac, 1968;Geay et al, 1982). The reduced intake and the greater potential for lean growth suggest that DBM bulls require diets with increased energy and protein density (Fiems et al, 1990). The Piemontese (also known as Piedmontese) breed exhibits DBM in almost all offspring (Albera et al, 2004) but information on the intake and production traits of this breed is limited (Albera et al, 2001).…”

The effects of low-protein (LP) diets and rumen-protected CLA on DMI, ADG, carcass traits, and health status of double-muscled Piemontese young bulls were investigated. Forty-eight bull calves (BW = 237 ± 24 kg) were divided in 4 groups and housed in 12 fully slatted pens. Bulls were fed 2 diets differing in CP density [high-protein (HP) diet: CP = 145 g/kg of DM; LP diet: CP = 108 g/kg of DM] and top-dressed with 80 g/d of rumen-protected CLA or 65 g/d of hydrogenated soybean oil. Orts were collected weekly and feed intake was estimated on a pen basis, with 3 replicated pens for each treatment. Each bull was weighed monthly and examined for alterations of the locomotion system by using the locomotion score as an index of lameness and by counting the number of swollen joints. Carcass quality traits were measured at slaughter, after a feeding period of 332 d. Compared with HP, LP reduced ADG only during the first 4 mo of the trial (1.30 vs. 1.53 kg/d, P = 0.003). However, because of compensatory growth, over the whole trial, no significant effects attributable to CP or to additive were found on final BW (668 kg), ADG (1.19 kg/d), DMI (8.50 or 86 g/d per kg of BW(0.75)), dressing percentage (67.3%), carcass conformation (5.2 points), and carcass fat covering (1.87 points). Feed efficiency was affected by a CP × additive interaction (P = 0.030), with CLA improving feed efficiency when added to the LP diets, whereas feed efficiency was reduced with the HP diets. The addition of both LP and CLA reduced the number of bulls presenting swollen joints (P = 0.001), and LP improved the locomotion score (P = 0.021) compared with HP. It was concluded that 10.8 g/kg of CP density in the diet is sufficient for double-muscled Piemontese bulls. The reduction in CP density from 145 to 108 g/kg of DM, in addition to reducing the feeding cost, allows a strong reduction in N consumption without negative consequences on growth performance and carcass traits.

“…Lors de nombreuses expériences rapportées au tableau 3, la durée de l'engraissement a été fixée et semblable dans les groupes témoins et traités. Lorsqu'elle n'était pas fixée, elle a été soit plus courte avec une amélioration du gain de poids (Fiems et al 1990), soit plus longue suite à une détérioration du gain de poids des animaux (Cuitun et 4 / Composition de la carcasse L'addition de matière grasse dans les rations d'engraissement de bovins a entraîné de légères augmentations du poids de la carcasse (tableau 4).

Utilisation des matières grasses chez les bovins à l’engraissement

L’incorporation de matière grasse dans les rations d’engraissement de bovins est une technique courante. Différents buts sont poursuivis : augmenter la teneur en énergie de la ration, faciliter la finition des animaux ou manipuler la teneur en acides gras insaturés de la graisse. L’incorporation des matières grasses se fait sous forme de graisses purifiées d’origine végétale ou animale ou sous forme de graines ou de fèves oléagineuses. Généralement, ces dernières subissent des traitements technologiques, avec comme conséquence, par exemple, une augmentation des acides gras à chaîne plus courte et saturés. Vu l’origine extrêmement variée des graisses utilisées, les effets observés chez les animaux sont parfois divergents. L’utilisation de graisses dans des rations d’engraissement a tendance à réduire l’intensité des fermentations dans le rumen et à les orienter vers une production plus importante d’acide propionique. Les données de la littérature indiquent que l’incorporation de matière grasse a tendance à réduire la digestibilité apparente de la matière sèche et de la matière organique et à augmenter la digestibilité de l’extrait éthéré. Les principaux effets sur les performances zootechniques sont une réduction de la durée d’engraissement, une augmentation des gains de poids, une réduction des ingestions, et par conséquent une amélioration de l’indice de consommation. Les auteurs signalent généralement une augmentation du poids des carcasses et du rendement à l’abattage. Les carcasses sont souvent plus grasses. La composition chimique de la viande et celle du muscle, c’est-à-dire de la viande maigre, ne semblent pas être modifiées. La supplémentation avec des graisses d’origine animale entraîne une diminution plus ou moins importante de la proportion des acides gras insaturés. A l’opposé, l’utilisation des graisses d’origine végétale se caractérise par une augmentation de la proportion des acides gras insaturés.
