| A trial was conducted to study the effects of feed form and the inclusion of fiber in the diet on feed and water intake of chicks from 6 to 9 d and 18 to 21 d of age. There were 12 treatments arranged factorially with 2 feed forms (mash and 2-mm pellet) and 6 diets consisting in the combination of 3 insoluble fiber sources (OH, oat hulls; RH, rice hulls; 92 ABSTRACTS OF PAPERS SFH, sunflower hulls) at 2 levels of inclusion (2.5 vs. 5%). Also, a control diet based on rice, soy protein concentrate, and fish meal without any additional fiber was formulated and offered either in mash or pellet form. The control diets had 3,200 kcal AMEn/kg, 1.4% total lysine, and 1.6% crude fiber and the hulls source was included in the experimental diets at expenses (wt/wt) of the whole diet. Each of the 14 treatments was replicated 6 times and the experimental unit was a cage with 14 chicks. Water intake (WI), feed consumption (FI), and the WI:FI ratio were recorded per replicate. Chicks fed pellet had higher WI and FI (P ¡Ü 0.001) than chicks fed mash in both periods. The WI:FI ratio was higher in chicks fed pellets (2.23 vs. 2.09 g:g; P ¡Ü 0.001) only from 18 to 21 d of age. Type of fiber did not influence any trait in any of the 2 periods. Level of hulls of the diet increased WI (70.1 vs. 74.4 vs. 75.2 g/d for control, 2.5%, and 5% hulls inclusion; P ¡Ü 0.05) and FI (151 vs. 158 vs. 166 g/d for control, 2.5%, and 5% hulls inclusion; P ¡Ü 0.05) from 18 to 21 d but not from 6 to 9 d of age. The WI:FI ratio was not modified by level of hulls in any period (P > 0.05). We conclude that pelleting the feed and increasing the level of hulls of the diet increase WI and FI of chicks but that type of hulls does not have any affect. The inclusion of hulls in the diet at the proposed levels increases both WI and FI but WI:FI ratio was not modified. | |
