“…Consequently, the gizzard needs to work harder for corn than for wheat based diets. In contrast, Frikha et al (2011) did not observe any difference in relative weight of the GIT or the gizzard, or gizzard pH at 120 d of age in pullets fed corn or wheat. The author has not found any report on the influence of the main cereal of the diet on the development of the GIT in laying hens.…”

“…Also, fine grinding of the corn but not of the wheat, reduced the relative length of the different segments of the GIT. In 120 d of age brown egg laying pullets, Frikha et al (2011) reported no differences in relative weight of the GIT and of the gizzard and on gizzard pH when fed mash diets based on corn or wheat, with fine, medium, or coarse particle size. Moreover, Saldaña et al (2015a) reported at 17 wk of age, that pullets had heavier gizzard and GIT when fed mash diets based on corn or wheat than when fed crumble diets based on the same cereals.…”

“…In contrast, Lott et al (1992) reported that corn ground through a hammer mill with a screen opening of 9.59 mm, which resulted in coarse particles (GMD ≃,1,200 μm), significantly decreased 21 d BW and increased FCR compared with corn ground through a screen with an opening of 3.18 mm (GMD ≃, 680 μm). In brown-egg laying pullets, Frikha et al (2011) reported that pullets fed the finer diet (6-mm screen) had higher BW gain and better FCR than pullets fed the medium and the coarser diets (8-and 10-mm screen) from 1 to 45 d of age, but not thereafter. These data emphasize the importance of age on FI and FCR of the bird.…”

“…Feed technology is of paramount importance in this respect (Amerah et al, 2007;Amerah et al, 2008;Frikha et al 2011). Type of cereal and particle size of the cereal used in diets have gained increasing attention from the poultry industrial in recent years.…”

“…Results revealed that the particle size did not alter significantly the digestion process and nutrient absorption, and may be used in the preparation of diets for laying hens. The physical form and particle size of the diet are among the factors that interfere with the morphological and physiological characteristics of the digestive tract of birds, damaging the villi or favoring microbial growth (Engberg et al, 2004;Frikha et al, 2011;Yegani & Korver, 2008).…”

ABSTRACT. The influence of maize corn size and texture on the performance parameters of laying hens and power consumption required for grinding maize corn were evaluated. The experiment was carried out on 384 Isa Brown hens, 36 weeks old, penned in a conventional aviary with 562.5 cm 2 bird -1 stocking rate. The treatments were distributed in a completely randomized 2 x 3 factorial design (maize textures: flint and dent; and milling degree: fine, medium and coarse) with eight replicates of eight birds per plot. Data were evaluated with SISVAR and means were compared by Tukey's test at 5% probability. Difference was reported for the variable texture and flint increased the variables feed intake and egg weight. Significant difference in the characteristics of egg quality occurred only for the colorof the yolk. Larger corn sizes consumed less electricity during grinding. The maize flint cultivar had a lower 31.7% power consumption when compared to that of the dent cultivar.Keywords: feed consumption, energy efficiency, processing, production of eggs.Granulometria e textura do milho: parâmetros produtivos, qualidade dos ovos de poedeiras comerciais e consumo de energia elétrica RESUMO. O objetivo foi avaliar como os fatores granulometria e textura do milho podem alterar os parâmetros de desempenho produtivo de poedeiras comerciais, bem como o consumo de energia elétrica para moagem dos grãos. Foram utilizadas 384 poedeiras da linhagem Isa Brown com 36 semanas de idade, alojadas em aviário de produção convencional com taxa de lotação de 562,5 cm 2 ave -1 . Os tratamentos foram distribuídos em delineamento inteiramente ao acaso em esquema fatorial 2 x 3 (texturas de milho: duro e dentado e graus de moagem: fino, médio e grosso), com oito repetições de oito aves por parcela. Os dados foram avaliados com o auxílio do pacote estatístico SISVAR com médias comparadas pelo teste de Tukey a 5% de probabilidade. Foi constatada diferença para o fator textura, em que a textura dura apresentou aumento nas variáveis: consumo de ração e peso dos ovos. As características de qualidade dos ovos demonstraram diferença significativa apenas quanto à cor da gema. Maiores granulometrias consumiram menos energia elétrica durante a moagem. A cultivar de milho duro teve consumo de energia elétrica 31,66% menor comparativamente à cultivar dentado.Palavras-chave: consumo de ração, eficiência energética, processamento, produção de ovos.

Abstract 18Twenty-four raw materials, harvested or produced in 2013 and commonly used in animal 19 feed, were used to measure their hydration capacities through both water-holding capacity (WHC, g 20 H 2 O/g DM after 24h of water addition) and swelling capacity (SC, mL H 2 O/g DM during 60 minutes 21 after water addition, every 5 minutes during the first 30 min and then every 10 min). The raw 22 materials were provided in the form of whole seeds (F1 class; n=8), flour/mash/hulls (F2 class, n=8) 23 or pellets (F3 class, n=9). Hydration capacities were measured for unprocessed material and also 24 after grinding of whole seeds (1, 3, 5 or 8 mm grid). The raw materials were analysed for fibre 25 content to study the relation with WHC and SC. Moreover, WHC and SC were measured on twenty-
