[more ▼] This study investigated the influence of four modalities of wheat (Triticum aestivum L.) presentations on the performances and digestive tract characteristics of broilers (Ross). The variety of wheat was Meunier. The first dietary treatment (Milled) corresponded to milled wheat (hammer mill, sieve of 3 mm). The second treatment (Rolled) was related to rolled wheat. The third dietary treatment (Whole-Advanced) corresponded to 10 % whole wheat for first week of study (d 10 to d 17), 20 % whole wheat for second week of study (d 17 to d 24) and 30 % after d 24. The fourth treatment (Whole-Belated) was similar to the third, except a delay equals to 1 week (10 % for d 17 to d 24, 20 % for d 24 to d 31 and 30 % after d 31). Except for the first week of study, intake of Milled was inferior (p < 0.05) to other treatments. From the second week (between d 17 and d 24), growth related to Rolled was higher (p < 0.05) than two whole wheat treatments. From the third week (between d 24 and d 31), growth related to Rolled was also higher (p < 0.05) than Milled. Cumulated feed conversion ratio (FCRc) of Milled and Rolled was better (p < 0.05) than FCRc of whole wheat treatments (30 % of whole grain in fine). With this two whole wheat incorporation schemes, 20 or 30 % of whole grain was superior (p < 0.05) to Milled for FCR. The gizzards of broilers related to whole wheat were proportionally heavier (p < 0.05) than gizzards associated to Milled or Rolled. Rolled was not different (p > 0.05) from Milled for weights of gizzards.

[more ▼] This study investigates the effect of interaction between hardness of grains and modality of wheat (Triticum aestivum L.) presentation on starch digestion in broiler chickens. A digestive trial (without starvation) was conducted (d 34 to d 38) with 108 chickens (Ross) divided in 36 groups. Two varieties of wheat were included at 60 % in diets: Deben (soft, hardness = 27) and Folio (hard, hardness = 82). The first modality of presentation (Fine) corresponded to finely milled wheat (hammer mill, sieve of 2 mm). The second (Coarse) was related to coarsely milled wheat (hammer mill, sieve of 5 mm). The third dietary treatment (Whole) corresponded to 10 % whole wheat between d 10 to d 17, 20 % from d 17 to d 24 and 30 % after d 24. Hardness (varieties), modalities of presentation and their interaction did not influence ingested starch (p > 0.05). Hardness interacted significantly (p < 0.05) with presentation of wheat on excreted starch and starch digestibility. But quantities of digested starch were not significantly different between the six treatments (p > 0.05). The starch digestibility of Folio-Fine was significantly (p < 0.05) lower than five other treatments. Moreover, starch digestibility of Whole was (p < 0.05) better than Coarse for Deben only. On the other hand, starch digestibility was not significantly different between Deben-Coarse and Folio-Coarse (p > 0.05). Similarly, starch digestibility of Deben-Whole was not significantly different than Folio-Whole (p > 0.05). In conclusion, fine milling (2 mm) of hard variety (Folio) was involved in reduction of starch digestibility.

[more ▼] The objective of this study was to examine the effect of microbial contamination of the incubation residue on the in situ nitrogen degradability of Italian ryegrass. Microbial nitrogen in the bag residues was estimated by the feed 15N dilution procedure, and the incorporation of feed 15N into the adherent bacteria was assessed after isolating a bacterial pellet and determining its 15N enrichment. Isotopically labelled Italian ryegrass (fertilized with 15NH4 15NO3) was harvested either in spring (early cut) or in summer (late cut). Forages were incubated in the rumen of two steers for 6, 24 and48 h. The proportion of microbial N per unit of total N in the bag residue increased with incubation time, ranging from 184 to 853 mg microbial N/g totalN at 6 and 48 h, respectively. 15N enrichment in the bacterial pellet was highest after 6 h of incubation (3.6 mg 15N/g N) and then declined steadily (0.8 mg 15N/gN in 48-h residues). Microbial 15N represented up to 0.422 g/g total 15N in the bag residue, but the incorporation of feed 15N into bacterial N did not account for more than 57 mg/g 15N incubated, this incorporation rate decreasing progressively with incubation time. Correction of apparent N disappearance for microbial N resulted in higher values of N degradability, especially for the late cut grass. A further correction considering the amount of microbial 15N had little effect on the estimation of corrected N degradability values. Therefore, some of the feed 15N is incorporated into bacterial N, but this fraction has a minor effect on the estimation of total microbial N in the bag residue by the feed 15N dilution approach, and hence on the estimation of corrected degradability values.
