Research has been carried out to obtain oil from corn grown in the Khorezm region. The amount of protein, oil, starch and fiber in the composition of corn grains has been determined. Optimal indicators of the technology for obtaining corn oil by extraction with ethyl alcohol have been determined. The amount of oil in grain and corn germ has been studied. Ethanol seed oil separation is exploring the advantages of the wet process.

The aim of the present study was to evaluate the effect of replacing corn grain with citrus pulp (CSP) in the starter concentrate on performance and metabolism of dairy calves. Twenty-four individually housed Holstein calves were blocked according to birth date and weight and fed one of the following concentrates: (1) concentrate containing 64% corn and 0% CSP (0CSP); (2) concentrate containing 32% corn and 32% CSP (32CSP); and (3) concentrate containing 0% corn and 64% CSP (64CSP). Animals were fed 4 L of milk replacer daily (20% crude protein, 16% ether extract) divided in two meals (at 0700 hours and 1800 hours). The starter feed and water were provided ad libitum. Starter intake and faecal score were monitored daily. Bodyweight and measurements (withers height, hip width and heart girth) were recorded weekly. Blood samples were collected weekly, and ruminal fluid samples at 4, 6 and 8 weeks of age, 2 h after the morning feeding. After 8 weeks, animals were harvested to evaluate the development of the proximal digestive tract. Concentrate composition had no effect (P > 0.05) on concentrate intake, weight gain, bodyweight, body measurements, and faecal score. However, there was a lower concentration of ruminal butyrate (P < 0.05) in animals receiving 0CSP than in those fed the starter containing CSP. The 0CSP concentrate resulted in a lower (P < 0.05) total weight of the proximal digestive tract, weight of the reticulum–rumen and weight of the omasum than did the other concentrates. The length of the rumen papillae was the greatest (P < 0.05) in 32CSP-fed animals. However, papillae area in animals fed 32CSP concentrate was larger (P < 0.05) than that in 0CSP- and 64CSP-fed animals, with no difference observed between these latter two treatments. However, 0CSP-fed animals showed a higher proportion of abomasum than did the animals fed 32CSP and 64CSP concentrates. The replacement of 50% or 100% of corn by CSP in the starter feed of dairy calves did not affect performance and probably contributed to the better development of the proximal digestive tract.

Two experiments were carried out to evaluate the effects of particles sizes on contents of neutral detergent fiber (NDF) by using nylon bags F57 (Ankom®) and non-woven textile (NWT 100 g/m²). In the first experiment, to check contents of NDF obtained with each one of the textilles, quantitative filter paper (purified cellulose) was used as analytical standard. The material was processed in a 1 or 2 mm and put in the bags in a ratio of 20 mg of dry matter/cm² of surface. The analyses were performed in a fiber analyser (Ankom220) and using a heat-stable a-amylase. No effects of particles sizes were found. In the second experiment, it was used samples of forage (signal grass hay, sugar cane, coastcross hay, corn straw, corn silage, and elephant grass at 50 and 250 days of growing after cutting), concentrate feeds (sorghum grain, gluten meal, citrus pulp, cottonseed meal, soybean meal, wheat bran, corn grain, whole soybean, and soybean hulls), and feces of cattle of animals fed diets containing 15 or 50% of concentrate. The samples were prepared, put in bags, and analyzed as described in the previous experiment. In both experiments, the smallest contents of NDF were found by using nylon bags, indicating loss of particles through the bag porosity. It is suggested grind of samples by using 1-mm screen sieve, which provides efficient extraction of cell content by the action of neutral detergent and a greater specific surface by the action of the heat-stable a-amylase enzyme. The use of particles ground at 2-mm overestimates NDF contents.

This study investigates the methane and carbon dioxide gas production, dry matter degradation, and final pH values obtained during the in vitro incubation of corn grain, soybean hulls, citrus pulp, corn silage, and crude glycerin. Experiments were performed using a randomized block design with four incubation periods. Each period featured four replicates per ingredient and four blanks, totaling 16 repetitions per ingredient. The lowest total amount of produced gas (37.96 mL gincubated DM-1) and the lowest final pH value (4.95) were obtained for crude glycerin (P < 0.05), which, however, exhibited the highest (P < 0.05) DM degradation. Citrus pulp produced the largest amount (P < 0.05) of CH4 per gram of incubated DM (13.56 mL g-1). However, when methane production was expressed per gram of degraded feed, the ingredients with lower degradation values, such as soybean hulls and corn silage, produced more CH4 per gram of degraded DM. Citrus pulp and corn grain produced more (P < 0.05) CO2 per gram of incubated DM. However, per gram of degraded food, citrus pulp produced the largest amount of CO2 (P < 0.05). Crude glycerin and corn grain produced less methane (per gram of degraded feed) than citrus pulp, soybean hulls, and corn silage. Differentiation of ingredients based on their methane production ability is important to express methane production per unit degraded food mass.

Replacement of corn by citrus pulp or coffee hulls explores the potential of dairy cows to digest fiber-rich feedstuffs. However, for the State of Minas Gerais, Brazil, replacing citrus pulp by coffee hulls may reduce milk production costs, since citrus pulp needs to be imported from another state, while coffee hulls are highly available at essentially no cost. The objective of this experiment was to evaluate the performance of crossbred cows fed concentrates containing 25% coffee hulls (Coffee) or 25% citrus pulp (Pulp) as a replacement for ground corn grain (Corn; 47.4% in the concentrate). Forty-two cows were blocked based on milk yield and allocated to one of the three treatments for 56 days, following a 14-day standardization period. Concentrates were fed twice a day during the milking routine, 1 kg to each 2.5 kg of the average milk yield for the block, determined at the end of the standardization period. The daily 3.5% fat-corrected milk yield was 7.5 kg for Corn, 7.9 kg for Pulp and 6.2 kg for Coffee (P < 0.01). Cows consuming coffee hulls had greater body weight loss (P = 0.03). Feed orts during milking amounted to 30% of the concentrate offered in Coffee, greater than the other treatments throughout the experimental period (P < 0.01). The mean daily intake of coffee hulls was 575 grams. The frequency of cows reluctant to enter the milking parlor yoke was 10% for Coffee and 1% for the other two treatments (P < 0.01). There was no detectable effect of coffee hulls on cow temperament and frequency of defecation during milking, as well as on somatic cell count (P > 0.26). The Pulp concentrate provided the highest financial efficiency, while Coffee was the least efficient (P < 0.01). These data suggest that the potential of use of coffee hulls is low when added at rates equal to or greater than 25% of the concentrate offered during the milking routine.

AbstractUtilization of lipids-free waxy starch by distillery yeasts in fuel ethanol production can contribute to better management of renewable resources, like cereals, especially maize Zea mays L. But the efficient conversion of starch into glucose-rich fermentable substrate, and subsequently to ethanol, needs more research on hydrolysis and fermentation conditions. The aim of this study was to evaluate the lack of natural corn grain lipids on the process of simultaneous saccharification and fermentation using chemometric techniques of designed experiments, commercial enzymatic preparations and distillery yeasts Saccharomyces cerevisiae CCY-11-3. Based on the results and statistical software support we can conclude that extraction of lipids from corn grains did not lead to statistically significant increase or decrease of glucose concentration in starch hydrolysis. The ethanol concentration in fermentation mash according to analysis was not statistically significantly affected by lipids extraction. The separated lipids could serve as a source of very valuable corn oil.
