Thirty-two Holstein steers averaging 369 kg were used to evaluate the feeding value of high moisture barley (HMB). The HMB was harvested at 74.8–77.8% dry matter and ensiled whole in a concrete silo, or was treated with paraformaldehyde or organic acid mixture (propionic 80%, acetic 15% and benzoic acids 5%), and stored on a barn floor. Dry barley (DB) was harvested from the same field at a moisture level of 13.4%. Steers were fed barley ad libitum plus grass silage at the rate of 1.0% of body weight. At feeding, the dry matter content of the DB and HMB was higher than at harvesting. Total nitrogen was higher (P < 0.05) in ensiled HMB and paraformaldehyde-treated HMB compared to DB and organic-acid-mixture-treated HMB. Soluble nitrogen was reduced (P < 0.05) by the paraformaldehyde treatment. Cellulose was not significantly (P > 0.05) affected by any treatments. Daily gain, dry matter intake, feed efficiency, rib eye area, fat over 12th rib, 12th rib fat, bone and muscle were not influenced (P > 0.05) by the different treatments. Carcass yields were significantly (P < 0.05) higher for steers fed DB and ensiled HMB compared to those fed paraformaldehyde- and organic-acid-treated HMB.

Three factorial experiments were conducted to determine the relative feeding value of dry barley (DB) and high-moisture barley (HMB), and to evaluate the influence of method of ensiling (Pit vs. Harvestore® (HAV) silo), source of roughage (hay vs. silage), and level of concentrate (90 vs. 75%) on the performance and carcass characteristics of feedlot cattle. In exp. 1, 252 steers (initial wt 357 kg) were assigned on the basis of weight to six treatments (two pens × 21 animals per pen). A mixed diet consisting of 85.2% barley grain (dry matter (DM) basis) was offered free choice. The barley portion of the ration consisted of either 0, 25, 50, 75 or 100% DB with the balance being HMB from a pit silo. The sixth treatment consisted of feeding 100% HMB for the first 57 d and 100% DB for the remainder of the trial. Overall average daily gain (ADG) for steers fed 100% DB (1.70 kg d−1) was significantly higher than observed for animals fed 100, 75 or 50% HMB (1.46, 1.49 and 1.56 kg d−1, respectively). The kg of feed DM required per kg gain (FC) varied between 5.76 and 7.13 and was not (P > 0.05) influenced by treatment. No differences (P > 0.05) were observed in carcass characteristics. In exp. 2, 360 steers (initial wt 340 kg) were allotted on the basis of weight to six treatments designed to evaluate the effect of source (Pit vs. HAV) and level of HMB, in diets containing 10.2% silage, on animal performance. Overall ADG (1.11 – 1.17 kg d−1), FC (6.66 – 7.01) and carcass characteristics were similar (P > 0.05) for animals fed Pit HMB, HAV HMB and DB. In exp. 3, 264 weanling calves (initial wt 216 kg) were allotted on the basis of weight to six treatments which differed in type of barley (HMB vs. DB), source of roughage (hay vs. silage) and level of concentrate (75 vs. 90%; DM basis). The feeding period was 127 d. Daily gains varied between 0.78 and 0.91 kg d−1 and FC ranged from 6.40 to 7.10 and were not influenced (P > 0.05) by source of barley or source or level of roughage. While animals fed DB had significantly higher ADG than those fed HMB in exp. 1, the overall results from the three experiments indicate that on a DM basis HMB has similar feeding value to DB, and that there is no major difference between Pit and HAV-stored HMB for feedlot cattle.

Feeding Value

Three experiments were conducted (1) to compare the feeding value of dried shelled corn and acid-treated high moisture (HM) corn and (2) to determine the effects of rolling acid-treated HM corn for all-concentrate diets fed to finishing beef-type cattle and to growing and finishing Holstein male calves. In a 120-day finishing period, Hereford and Hereford × Charolais steers performed similarly with respect to gain, feed efficiency, carcass measurements and grade on whole dried corn and on whole and rolled acid-treated HM corn. No health problems occurred during the feeding trial in which gains averaged 1.49 kg per day. The performance of Holstein male calves fed from a starting weight of 95 kg to 385 kg also demonstrated that acid-treated HM corn was comparable in feeding value to dried shelled corn. While growth of calves on whole and rolled HM corn was similar (1.24 kg/day), four calves receiving rolled HM corn were lost from the experiment due to acute bloat, laminitis and peritonitis. One calf fed whole dried corn had peritonitis and was also removed from the experiment. Incidence of liver abscesses among cattle completing the trials was 28 and 26% for beef-type and Holstein cattle, respectively. Rumen abnormalities, i.e. clumping of papillae, ulceration of rumen epithelium and accumulation of hair, were evident in calves on all treatments. Rolling of HM corn did not improve digestibility of dry matter (P > 0.05), and percentage of whole kernels in feces of steers fed whole dried or whole HM corn was low (0.45 and 0.32%, respectively).

Wilting grass before ensiling has become a firmly established practice, since it provides economic advantages due to the increment of the dry matter content of the forage before ensiling. Most forage crops contain less than 20 per cent of dry matter when they are cut thus reduction of the weight of crop to be transported provides advantages (Gordon et al., 1999). Also, research has shown that such practices yield improved and reduced effluent loss from the silo and higher feeding value of the silage. Wilting of grass prior to ensiling has been widely adopted as a means of reducing effluents produced and improving the fermentation quality of silage. The aim of this research was to assess the effect of differing wilting periods and silage moisture levels of silage quality and microbial growth levels.

SUMMARYA total of 156 pigs of the Large White breed were used in a series of four experiments to test the suitability of barley which had been stored with a high moisture content as an ingredient in the diets of growing pigs. Barleys with mean moisture contents of 26·3%, 28·1% and 21·2% and a range from 19·6% to 30·5%, from three successive harvests were used.In all the trials there was evidence that the use of moist barley in diets for growing pigs had an adverse effect on live-weight gain and feed conversion ratio, the effect being independent of whether feed intakes were equated on the basis of the dry-matter content of the diets. In one of the experiments performance was depressed to the extent of causing changes in carcass characteristics. The performance of pigs given rolled barley was similar to that of others given ground barley.

A total of 120 steers were fed either barley silage (BS) or triticale silage (TS) combined with barley (B) or high-moisture barley (HMB) grain, as a total mixed ration in a 2 × 2 factorial design with three replications. The barley and triticale yields were 9.8 and 8.7 t ha−1, respectively. No differences (P > 0.05) in weight, average daily gain, dry matter intake or feed efficiency were observed for treatments or interactions. TS can be used to replace BS at moderate levels in growing steer rations containing barley grain. Key words: Barley, triticale, silage, steers, performance

1. Pigs were fitted with re-entrant duodenal cannulas anterior to the pancreatic duct, and total collections of digesta were made for 12 h periods.2. Maize–soya-bean diets were made from maize which had been harvested with a dry-matter content of 770 g/kg and either dried, preserved with acetic or propionic acid or ensiled naturally. The pigs received two meals of these diets/d at 12 h intervals, and the amount of digesta flowing through their cannulas was measured.3. Between 4.5 and 5.25 l of digesta flowed through the cannulas in the 12 h collection period, 0.9 of the total 12 h flow passed through the cannulas in the first 9 h with the dry-maize diet and 0.8 with the acid-treated-maize diets.4. The mean total dry matter intake was 358 g/meal, and 304 g dry matter passed through the duodenal cannulas in the 12 h collection period. The corresponding intake and flow of nitrogen (g/12 h) was 11.1 and 9.6, and for chromic oxide 1.13 and 0.94.5. The pigs consumed 205 g starch (total α-linked glucose polymers)/meal, and 1.5 g free glucose/meal. Only 110 g starch and 4.1 g free glucose reached the duodenal cannulas, suggesting that digestion and absorption of up to 92 g glucose had taken place anterior to the pancreatic ducts.

Background: Tropical grasses, such as elephant grass, have high moisture content during its ideal phenological state for silage. High moisture content hinders proper preservation and reduces the nutritive value of silage due to secondary fermentation and production of effluents. Adding feed materials with high dry matter content, such as murumuru (Astrocaryum murumuru) meal, is a potential alternative to improve silage yield. Objective: To determine the effects of including murumuru meal (0, 7, 14, 21, and 28%) on the fermentative characteristics, microbiological activity, aerobic stability, and chemical composition of elephant grass silages. Methods: A completely randomized design with five treatments and five replicates was used. Elephant grass was collected at 60 d of age, minced, and homogenized with murumuru meal. The mass was placed in experimental 15-L silos. The silos were collected and analyzed 45 d later. Results: Effluent production decreased (p<0.05) as the proportions of murumuru meal in silage increased. A quadratic effect (p<0.05) was observed on dry matter recovery. An increase (p<0.05) was observed in dry matter content, a decrease (p<0.05) in the neutral detergent fiber content, and an increase (p<0.05) in the non-fibrous carbohydrate content with the inclusion of murumuru meal. Conclusions: Addition of murumuru meal improves chemical composition and does not affect the fermentative characteristics of elephant grass silage, while it reduces effluent losses. Nevertheless, the inclusion of murumuru meal in the elephant grass silage decreased the time of aerobic stability.

SUMMARYStatistical analyses were carried out on the data obtained, under strictly controlled conditions in metabolism stalls, from 219 adult non-pregnant dry cows fed on seventyone different rations. The authors have calculated and studied the correlations between total water intake, faecal and urinary water losses, absorbed and available water, and the seventy-five other factors which were analysed in each of the seventy-one rations. Total water intake closely correlated with the dry-matter intake and also with the dry-matter content of the diet; forages with high moisture content enhance the total water intake which is also significantly correlated to the intake of nitrogen, fat and some mineral elements.Total water intake closely correlated with the dry-matter intake and also with the dry-matter content of the diet; forages with high moisture content enhance the total water intake which is also significantly correlated to the intake of nitrogen, fat and some mineral elements.Faecal water losses are strongly correlated with the dry-matter intake and on the faecal dry matter. Moisture content of the diet has no significant effect but increasing pentosans and crude-fibre intake enhance the losses.Urinary water excretion is closely related to the amount of absorbed water and to the dry-matter content of the diet; a highly significant correlation also exists between urinary water and urinary nitrogen and potassium. The amount of water excreted in the urine may affect the utilization of digestible nitrogen and potassium.Available water is increased logarithmically when total water intake rises arithmetically. Feeds with high moisture content thus enhance the amount of available water.
