Abstract The objective of this study was to evaluate the effect of adding monensin into high-concentrate diets based on either finely-ground or high-moisture corn during the transition from adaptation to finishing diets on ruminal pH of cannulated Angus and Nellore steers. Four 30-mo-old Nellore and four 30-mo-old Angus steers were divided (± 550 kg) into two 4 x 4 Latin squares, where each square was composed by animals from same breed, and randomly submitted to a 2 x 2 factorial arrangement of treatments as follows: T1) Finely-ground corn + monensin; T2) Finely-ground corn; T3) High moisture corn + monensin; T4) High-moisture corn. Periods were divided as follows: 14 days of adaptation diets and 18 days of finishing diet (80% concentrate). The study lasted 149 days, including three 7-d washout intervals. The rumen pH was assessed continuously via data loggers on days 4, 8, 12, 16, 20, 24 and 28. Interactions between breed and days were observed for DMI (P = 0.02) and pH duration below 5.6 (P = 0.01), where Angus steers had greater DMI and spent a longer time below 5.6 than Nellore animals on days 12, 16, 20, 24 and 28. The addition of monensin decreased (P = 0.01) DMI on days 16, 20, 24 and 28. Regarding pH duration and area below 5.6, an interaction between breed and corn was observed (P = 0.001), in which Angus steers fed finely-ground corn spent a longer time (416 min/day) and had a larger area (224.6 min x pH units/day) below 5.6 than animals from other treatments. For mean pH, steers consuming high-moisture corn had higher pH (6.45 vs. 6.29); and an interaction was observed (P = 0.03) between breed and monensin, where monensin addition decreased pH for Angus (5.96 vs. 6.18), but not for Nellore steers (6.68 vs. 6.63). The feeding of monensin and finely-ground corn did not positively impact rumen pH of Angus steers.

Two trials were conducted involving 44 individually fed growing-finishing pigs to evaluate the effect of corn moisture content and method of processing of corn on performance. Digestible energy values of the diets were determined. When pigs had free access to feed and water, those fed high moisture corn consumed less dry matter and gained less rapidly than those fed artificially dried corn. The digestible energy values of diets containing whole corn were less than those of diets containing rolled or ground corn. The gain/feed ratio for diets containing whole corn was lower in the first trial but similar to other diets in the second trial.

Abstract The aim of this survey was to identify silages and roughage sources adopted in the beef finishing diets. Eighty-two feedyards, located in 10 states, were surveyed from January to March 2019 for their feeding practices. Feedlot owners and nutritionists were interviewed by using a common survey form. The form consisted of 5 questions, including feedlot location, feedlot capacity and the number of animals serviced yearly, breed, silages and roughage sources, and roughage: concentrate ratio. Results were tabulated in an Excel spreadsheet for each feedlot. The number of responses per question, and the mean, minimum value, maximum value, and mode (most frequently occurring value) were calculated. Feedlot capacity ranged from 300 to 35,000 (mode = 3,000) and cattle serviced yearly per feedlot ranged from 400 to 90,000 (mode = 6,000). Nellore breed and crossbreed represented 74 and 26% % of finished animals, respectively. Roughage: concentrate ratio ranged from 40: 60 to 10: 90. Thirty-five percent of feedlots adopted 20: 80 ratio, followed by 15: 85 (16%) and 10: 90 (16%) ratios. Whole-plant corn silage was the most common roughage source (57%; Figure 1), followed by sugarcane bagasse (17%), tropical grass silages (16%), and whole-plant sorghum silage (11%). Nutritionists also cited hay (9%), sugarcane silage (5%), and fresh sugarcane (4%) as roughage sources. High-moisture corn, snaplage (grain, cob, husk, shank), and reconstituted grain corn were used by 20, 11, and 1% of feedlots, respectively. Reconstituted grain sorghum was included in 4% of the diets. Thus, 36% of feedlots adopted grain silages (corn and sorghum) in the diets. Overall, Brazilian feedlots have used high-energy finishing diets and corn is the most widely grown crop for silage. Feedlots have shown interest in using grain silages to maximize starch digestion, especially because Brazil grows flint corn and silage machinery industry has made available new equipment.

Twenty primiparous and multiparous Alpine breed goats at approximately 80 days of lactation were used in this experiment. The animals were housed individually in metal cages and distributed according to milk production in five 4 × 4 Latin squares. The experimental diets used in the experiment presented concentrate:forage ratio of 65:35. The treatments were characterized by increasing levels of 0, 33, 67 and 100% of high moisture corn silage (HMCS) replacing corn dry grain (CDG). Average intake of DM (1.62 kg/day, 3.90 % BW), CP (0.22 kg/day), NFC (0.76 kg/day) and TDN (1.29 kg/day) were not influenced by levels of HMCS. However, intake of NDF (0.53 kg/day) was significant for the different level of HMCS. Daily milk production and production of milk correct at 3.5% of fat, feed efficiency (MP/DMI), fat percentage, protein, lactose, total solids and milk urea nitrogen, with means of 1.86; 1.69; 1.11; 2.96; 2.85; 4.36; 10.96 and 17.1, respectively, were not influenced by the levels of HMCS. Percentage of non fat solids (8.00%) was affected by replacing levels of HMCS. The use of high moisture corn silage in the diet does not change milk production and it can be applied in total or partial substitution to dry corn grain in the feeding of milk goats.

Carcass Measurement

1. A feeding trial was carried out using fortyeight Large White pigs, individually fed in a Danish type piggery. Six different diets prepared at two levels of digestible energy and three levels of crude protein were fed to eight replicates consisting of four hogs and four gilts per replicate. A record was maintained of the weekly live-weight gain and food was given at a defined restricted level in relation to the live weight. Carcass quality was assessed by complete dissection into visible lean, fat and bone etc.2. Of the main effects, energy, supply was without significant effect upon growth, food conversion efficiency (FCE) or any carcass characteristics except body length which was increased with a high energy level. The protein level in the diet had a significant effect upon the percentage of carcass lean and the killing-out percentage, the higher levels of protein increasing both these measurements significantly. Gilts were significantly superior to hogs in every carcass measurement although hogs grew significantly faster.
