Abstract: Eight broiler chicken diets were produced by using 2 pellet conditioning temperatures (65 and 85°C) and 4 pellet retention times in the conditioner (3, 9, 14, and 20 s). The effect of dietary treatments on pellet physical quality (intact pellet percentage, pellet hardness, pellet durability index, and water activity), growth performance (0 to 21 and 0 to 42 d), apparent ileal digestibility (CAID) of dry matter, crude protein and starch, and ileal digestible energy (IDE) was evaluated. 1,536 broiler chickens were randomly assigned to 8 dietary treatments (8 replicates of 24 chickens each). On d 42, 2 chickens per replicate were randomly selected for ileal content collection to evaluate dietary CAID and IDE. The greater conditioning temperature (85°C) improved pellet percentage, durability, and hardness (P< 0.001), and promoted greater feed intake, but also increased feed conversion by 1.2% (0 to 42 d, P < 0.05). The retention time of 20 s enhanced both weight gain and feed conversion (P < 0.05). Multiple interactions were observed for digestibility traits (P < 0.001). At 65°C, CAID of dry matter, crude protein and starch, and IDE increased with longer retention times. However, all digestibility coefficients and IDE decreased when diet was conditioned at 85°C and retained for more than 9 s. In conclusion, conditioning at 85°C with longer retention times improved pellet physical quality, but reduced digestibility traits and growth performance of broiler chickens. However, conditioning at 65°C with retention times shorter than 14 s also had detrimental effects on ileal nutrient digestibility, digestible energy, and growth performance.

Cotton fiber are tubular cells which develop from the differentiation of ovule epidermis. In addition to being one of the most important natural fiber of the textile group, cotton fiber afford an excellent experimental system for studying the cell wall. The aim of this work was to isolate and characterise the genes expressed in cotton fiber (Gossypium hirsutum L.) to be used in future work in cotton breeding. Fiber of the cotton cultivar CNPA ITA 90 II were used to extract RNA for the subsequent generation of a cDNA library. Seventeen sequences were obtained, of which 14 were already described in the NCBI database (National Centre for Biotechnology Information), such as those encoding the lipid transfer proteins (LTPs) and arabinogalactans (AGP). However, other cDNAs such as the B05 clone, which displays homology with the glycosyltransferases, have still not been described for this crop. Nevertheless, results showed that several clones obtained in this study are associated with cell wall proteins, wall-modifying enzymes and lipid transfer proteins directly involved in fiber development |
