“…No significant effects of corn particle size on digesta pH in the gastrointestinal tract at the time of slaughter were observed. Previous studies have shown that there were no effects of corn particle size on rumen pH in beef cattle (Galyean et al, 1979) and dairy cows (Callison et al, 2001;Rémond et al, 2004;Ferreira et al, 2007). Wang et al (2008) observed that starch content varying from 28% to 46% did not affected digesta pH in the abomasum and the small intestine.…”

“…Grain processing can affect rumen fermentation (Ferreira et al, 2007;Horadagoda et al, 2008) and starch digestibility (Theurer et al, 1999;Callison et al, 2001;Rémond et al, 2004). Lesmeister and Heinrichs (2004) reported that steam flaked corn stimulated the development of rumen mucosa compared with rolled and whole corn in neonatal calves.…”

“…Thus, the more starch digested, the more the digestion products are absorbed and the animal reaches satiation. Ferreira et al (2007), in order to evaluate the selection of cattle diet, studied foods with different energy content (thin, thick and flaked corn) and found no difference in the intake of degradable starch in the treatments. Overton et al (1995) reported decreased linear effect for DM intake, when corn was replaced by barley in the diet of lactating dairy cows.…”

Five Holstein cows were distributed in a 5x5 latin square design to assess the effect of replacement levels of dry ground corn grain (DGCG) by high moisture corn silage (HMCS) on intake, total nutrient digestibility and plasma glucose, according to the following treatments: 1) 100% DGCG; 2) 75% DGCG and 25% HMCS; 3) 50% DGCG and 50% HMCS; 4) 25% DGCG and 75% HMCS; 5) 100% HMCS. The experiment lasted 70 days, divided into five phases of 14 days each. The digestibility was obtained using chromic oxide (Cr 2 O 3 ) as the indicator. Fecal samples were collected twice daily and blood samples were collected on the last day of each period before the first meal (0h) and 2h, 4h, 6h and 12h after the meal. There was no effect (P>0.05) on the intake of dry matter (DM), neutral detergent fiber (NDF), acid detergent fiber (ADF) and starch. The total apparent digestibility of DM, crude protein (CP), NDF and ADF were not affected (P>0.05) by the treatments, as well as the plasma glucose concentration. However, there was a decreased linear effect (P<0.05) for the protein intake and increased linear effect (P<0.05) for starch digestibility, as the level of HMCS was increased in the diets.Keywords: starch, digestibility, glucose, chromium oxide, processing Palavras-chave: amido, digestibilidade, glicose, óxido crômico, processamento RESUMO Cinco vacas da raça Holandesa foram distribuídas em quadrado latino 5x5 com o objetivo de se avaliar o efeito de níveis de substituição do grão seco de milho (GSM) pela silagem de grãos úmidos de milho

“…One of the main ways to increase the productivity of livestock is to feed them mixed feeds, namely feeds obtained by processing feed grains [1][2][3]. Currently, farmers and family farms in Uzbekistan have the opportunity to grow corn, barley, oats, and rye as feed grains for livestock, but they do not have small-scale grain grinders, so it is difficult to prepare mixed fodder for livestock.…”

One of the main ways to increase the productivity of livestock is to feed them with mixed feeds, namely feeds obtained by processing feed grains. Based on this, a constructive and technological scheme for the device for small-scale livestock farms such as maize and other cereals, namely rye, oats, wheat, barley, was developed. On this principle, a two-stage grinder with a fixed blade in the upper chamber and movable hammers in the lower chamber, which performs the work process, was developed, and its upper chamber hole surface dimensions were theoretically and empirically studied. It was found that Nm = 137.5 holes with a diameter of 20 mm are required for the exit of crushed pieces from the crushing chamber under ideal conditions when crushing a piece of corn-cob. In the experiments, the optimum granulometric composition of the primary crushed product was obtained when the holes of the crushing chamber were studied by changing the holes from 10 to 30 mm. According to theoretical calculations, when the holes had a diameter of 20 mm, the optimum granulometric.
