“…Corn density is influenced by genetic differences among cultivars, as well as other factors, according to Gutiérrez-Alamo et al (2008). Silva (2006) 3 ) density as determined in a gravity table, and concluded that higher density corn has higher energy value due to its higher starch content. Average crude protein values ranged from 7.2 to 9.1%, with an average 8.1%, similarly to those reported by Rostagno (2005) and Rostagno (2011), of 8.6 and 7.9%, respectively, but higher than those obtained by Agostini et al (2004), who obtained 7.3%, which is close to the minimum value obtained in the present study.…”

This study aimed at investigating factors that contribute to changes in the quality of corn used in compound poultry feeds. Samples were collected from 6488 bulk cargos received at a feed mill located close to Brasília, Brazil. The parameters studied were divided into two groups: those related to corn chemical composition, including crude protein (% CP), ether extract (% EE), crude fiber (% CF), nitrogen-free extract (% NFE), and estimated metabolizable energy (ME), and corn physical characteristics, including density, moisture, and grain physical damage. High coefficients of determination (R 2 ) and low coefficients of variation (CV) were determined for the chemical and physical parameters. The analysis of variance showed low to medium R 2 . Month, year, supplier, and their interactions influenced (p <0.05) all chemical properties, as well as density, moisture, and ME. Physical characteristics were less affected by those factors, except for quantity of damaged grains. The principal component analysis separated the physical and chemical factors. The coefficients of the first component explained 54% of the total variation between variables. The first principal component showed that NFE and ME increased as humidity decreased. The second component also showed a decrease of physical problems due to reduction in humidity. Results indicate that the feed mills should take preventive measures when selecting suppliers, and diets should be formulated according to the differences in chemical and physical composition of corn supplied in different months and years.

“…However, in feed milling, hard corn requires more energy for grinding and impairs particle-size uniformity. Moreover, higher concentrations of digestive enzymes are required to allow animals to properly digest these grains due to their vitreous characteristics (Silva et al, 2006).…”

The objective of this study was to evaluate the effect of corn texture and the particle size on broiler performance, carcass yield, nutrient digestibility, and digestive organ morphometrics. In Experiment I, 720 male Cobb chicks were distributed in a completely randomized experimental design with a 2 x 3 factorial arrangement, consisting two corn textures (dented and hard) and three corn particle sizes, was applied, with four replicates of 30 birds each. Corn particle size was classified according to geometric mean diameter (GMD) as fine - 0.46 mm; medium - 0.73 mm, and coarse - 0.87 mm. In Experiment II, 120 broiler chicks were used to evaluate corn digestibility during the periods of 16 to 22 days and 35 to 41 days of age, using the method of total excreta collection. In Experiment I, corn particle size influenced body weight, average weight gain, feed intake and feed conversion ratio of 21-day-old birds. Corn texture and particle size did not affect the performance of 42-day-old broilers or carcass traits. In Experiment II, there was no influence of corn texture and particle size on digestive organ weights. Dented corn increased nitrogen excretion in the first trial, and hard corn improved dry matter digestibility in the second metabolic trial. Corn with fine particle size promotes better performance of broilers at 21 days of age. Hard corn results in higher dry matter digestibility and lower nitrogen excretion, and consequently higher production factor in 42-day-old broilers

“…A ensilagem de grãos úmidos de milho é uma alternativa no armazenamento de grãos na propriedade rural, esta técnica diminui os custos por quilograma de animal produzido em relação ao milho seco (SILVA et al, 2006). Tradicionalmente, as silagens de grãos de milho são produzidas a partir de variedades pertencentes à espécie Zea mays L. Entretanto, grãos de milho doce pertencentes ao grupo saccharata, podem ser uma boa opção na produção de silagens de grãos úmidos, visto que, por apresentarem presença de alelos mutantes que bloqueiam a conversão de açúcar em amido, dão ao grão a caraterística de possuir um teor maior de açucares solúveis (ZÁRATE & VIEIRA, 2003), que podem favorecer as caraterísticas fermentativas em relação aos grãos de milho convencionais.…”

RESUMOEste trabalho foi realizado para avaliar as características fermentativas e a estabilidade aeróbica das silagens de grãos úmidos de milho: convencional, doce e reidratado. Foi utilizado um delineamento em esquema fatorial 3x3 com três tipos de milho (Fortuna, doce e reidratado) e três tratamentos de inoculação (sem inoculação; com inoculação bacteriana; inoculação bacteriana mais enzimas). Foram avaliados a estabilidade aeróbica (diferença entre temperatura do bulbo seco e temperatura das silagens) e os valores de pH com: 0, 24, 48, 72, 96, 168, 192, 216, 240 e 296 horas de exposição aeróbica. Adicionalmente, foram testados diferentes modelos matemáticos para estimar os valores médios de pH pós abertura. Houve interação (P < 0,05) entre os tratamentos de inoculação e tipos de milho para a estabilidade aeróbica e para pH nas horas 72, 168 e 192 após a abertura dos silos. SUMMARYThis work was carried out to evaluate the fermentation characteristics and aerobic stability, regarding the conventional high moisture corn grain silage (Fortuna variety), the high moisture sweet corn grain silage and the high moisture rehydrated corn silage. Data were statistically analyzed as a 3x3 factorial arrangement in a completely randomized design, and the factors were three types of corn (Fortuna, sweet and rehydrated) and three inoculation treatments (without inoculum, bacterial inoculum and bacterial inoculum plus enzymes). The aerobic stability values were assessed, collecting the temperatures from the room dry bulb and from the silage thermometers, and the pH values, at 0, 24, 48, 72, 96, 168, 192, 216, 240 and 296 hours after aerobic exposition. Additionally, different mathematical models to estimate the mean pH values after opening were tested. Interactions were observed (P<0.05) between types of corns
