Two experiments were conducted to determine the influence of feeding sulfur dioxide (SO2)-treated high-moisture barley (HMB) on the performance of lactating dairy cows and feedlot cattle. High-moisture barley was ensiled or treated with 1% (wt/wt) liquid SO2. In exp. 1, 36 lactating Holstein cows were assigned to three treatments for a 6-wk trial. Diets contained 35% rolled barley on a dry matter (DM) basis and differed only in the type of barley fed: dry barley, ensiled HMB or SO2-treated HMB. While no differences (P > 0.05) were observed in DM intake, milk yield, milk composition, milk taste or odour, cows fed SO2-treated HMB tended to have lower milk yield (21.7 kg d−1) than those fed ensiled (22.6 kg d−1) or dry barley (24.6 kg d−1). In experiment 2, 64 steers were allotted to four dietary treatments: (1) dry barley, (2) ensiled HMB, (3) SO2-treated HMB, and (4) SO2-treated HMB plus sodium bicarbonate. All diets contained 85% barley (DM) and were supplemented with thiamin (5.5 mg kg−1 DM). The results of the feedlot trial were confounded by the feeding of spoiled SO2-treated HMB, primarily between days 29 and 57 of the 96-d trial, at approximately 40% of the diet DM. During the period that spoiled SO2-treated grain was being fed, four steers (two from each treatment) developed polioencephalomalacia. Steers fed SO2-treated HMB (diets 3 and 4), had 10.1% lower DM intake (P < 0.01), 31% lower average daily gain and required 32% more DM per kilogram of gain than steers fed diets 1 or 2 (P < 0.001). Feeding SO2-treated HMB to either dairy or feedlot cattle cannot be recommended at the present time. Key words: Sulfur dioxide, preservative, barley, cattle (dairy, beef)

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.

Daily Gain

High-moisture barley (HMB) was ensiled or treated with 1% (wt/wt) liquid sulfur dioxide (SO2). Forty-five weanling pigs were allocated to five dietary treatments for 28 d. Diets consisted of: (1) dry barley, diet mixed every 28 d; (2) ensiled HMB, diet mixed daily; (3) SO2-treated HMB, diet mixed every 28 d; (4) SO2-treated HMB, diet mixed daily; (5) SO2-treated HMB, diet mixed daily and supplemented with thiamin. All diets contained 47% barley on a dry matter (DM) basis. Pigs fed diets 2 and 4 continued on test to 85 kg; diets formulated after 28 d contained 75% barley (DM basis). Feed intake, growth rate and feed:gain ratio were not influenced (P < 0.05) by treatment during the 28-d initial trial. For pigs fed SO2-treated HMB to 85 kg, feed intake and average daily gain were reduced by 9.8 and 9.0%, respectively. SO2 treatment effectively preserved high-moisture barley for 18 d at 16 °C; however, 61% of the dietary thiamin was destroyed by 7 d after diet mixing. Pigs fed diet 4 were thiamin depleted at slaughter; with a 38.5% higher erythrocyte thamin pyrophosphate effect, an 83% incidence of cardiac hypertrophy and thiamin levels in meat reduced to 7.6% of that present in the meat of pigs fed untreated HMB. Destruction of dietary thiamin appears to have been the primary factor responsible for reduced animal performance. Reduced ration palatability and toxicological effects on the digestive tract due to 75% SO2 treated grain in the diet (DM basis) may have also contributed to the reduced performance of growing-finishing pigs.

Effect Of Feeding

The aim of this study was to investigate the effect of two dietary treatments (liquid creep feed (LCF) and dry creep feed (DCF)) offered during the suckling period on feed disappearance, number of eaters, and intestinal enzymatic development at weaning in an on-farm study with 347 piglets. Piglets were allocated to either the DCF or LCF treatment from day 10 to day 24 postpartum for 9 h a day. Red ferric oxide (1%) was added to the diet to categorize piglets into eating categories (good eaters, moderate eaters, or non-eaters) via faecal swabs. At weaning, 40 piglets were sampled for intestinal enzymatic development. The LCF treatment increased the dry matter disappearance from day 10–18 (p < 0.001). The percentage of good eaters, moderate eaters and non-eaters did not differ between treatments (p > 0.05). The DCF pigs displayed greater average daily gain (ADG) pre-weaning (p = 0.024), and a greater body weight (BW) at day 61 (p < 0.001). The activity of lactase, maltase and sucrase in the proximal part of the small intestine were greatest (p < 0.001) in the DCF pigs.

Lactating Dairy Cows

Cereal grains can provide the major source of energy in diets in order to meet the nutrient requirements of high producing dairy cows. However the amount of starch that can be included in the diets of dairy cows is limited particularly if starch is rapidly fermented such as barley starch. Reduction of feed intake, rumen pH, milk fat test, microbial growth and other metabolic disorders are expected if ruminally degradable starch is fed in amount that cant be efficiently metabolized by rumen microbs. Various techniques for processing barley grain have been developed to decrease the degradability of dry matter in rumen without reducing its extent of digestion. McNiven (1995) showed roasting of barley is more effective treatment. The objective of this experiment was to study of effects the roasting and ammoniation of barley grain on rumen pH, feces pH, milk yield and milk composition in dairy cows.

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

An experiment was conducted to study the effect of micronutrients supplementation on body weight of cows, birth weight of calf, colostrums composition, milk yield and milk composition. Six animals were divided in to two groups viz. control and supplemented group. Control group was provided conventional diet and supplemented group was supplied conventional diet plus vitamin-mineral mixture (1g vitamix powder/1kg concentrate feed) respectively for two months before calving. In supplemented group the average daily gain of the cows was (49.17 g/d) higher (P<0.01) and the calves were 2 kg heavier in supplemented group compared to control group. Fat content and protein content of colostrum in supplemented group were also significantly higher (P<0.01 and 0.05). The milk yield, fat and protein values of milk were increased non-significantly by 1.03 kg/d/h, 2.8 g/kg and 0.3 g/kg respectively. Ca content of milk was more or less similar in both cases.

An experiment was conducted on early lactating dairy cows to study the effect of rumen protected choline (RPC) and methionine (RPM) on milk yield and composition. Fifteen crossbred dairy cows in early lactation (within 10 days of calving) were selected and randomly allotted to any one of the following three dietary treatments, T1 (Control)- with compound feed mixture containing CP- 20% and TDN- 68% , T2- T1+20g RPM and 20g RPC, T3- with compound fed mixture containing CP- 17%, TDN- 68% + 20g RPM and 20g RPC. All the experimental animals were fed as per ICAR feeding standards (ICAR, 2013). Results revealed no significant difference (p>0.05) in milk yield and 4 per cent fat corrected milk (FCM) yield between the three treatment groups. Among the milk constituents, animals in T3 had significantly higher milk fat (p<0.05), SNF (p<0.05), protein (p<0.05) and total solids (p<0.01) compared to those in T1 and T2. Milk urea nitrogen levels did not differ significantly among the three treatments and were within the normal range. The study showed that milk composition could be effectively improved by supplementing feed with rumen protected forms of choline and methionine in combination at lower dietary protein level without any reduction in milk yield.

The aim of the work is to evaluate the effects of different forage to concentrate rations on milk yield, composition and renneting properties of milk of Jonica breed goats. Twenty-four Jonica goats received diets with forage to concentrate ratio of 35/65, 50/50 or 65/35, providing respectively a low, medium and high energy level. Goats were divided into three homogenous groups and confined in individual pens for 152 days to assess the daily feed intake and milk yield and composition. The main conclusions show that animal body weight did not change significantly with the increasing levels of forage, whereas significant differences (P<0·05) for daily dry matter intake were observed in relation to the evolution of lactation. Milk production was influenced (P<0·05) by dietary treatments and was higher in the diet with the greatest energy level. Forage to concentrate ratios did not significantly affect milk characteristics, milk renneting properties, initial production, rate of increase until reaching the peak and rate of decline after peak production. However, the day of peak production and peak production of goats were linearly reduced when the level of forage increased within the diet. In conclusion, the results indicate that both forage to concentrate ratio and energy level improve goat's production without influencing the milk composition.

Milk yield in lactating range beef cows was estimated by milking 42 cows four times at approximately monthly intervals during the lactation. Milking was by machine after oxytocin injection. Weights of calves, before and after suckling, over a 24-hour period were used to estimate calf consumption. Breed-age group averages for 24-hour milk yield varied from 3.7 to 8.4 kg, with an overall average of 6.4 kg. Breed of cow accounted for 82.5% of the variance in milk yield in these data. Milk yield declined on the average by 0.02 kg per day of lactation. The correlation between calf consumption and milk yield was 0.58. Butterfat was 3.9% on the average, protein 3.5%, solids-not-fat 9.1% and total solids 13.0%. Breed-age group or month of test did not significantly influence milk constituent percentages, although butterfat and total solids tended to rise as lactation progressed.A good estimate of milk yield was obtained by one test milking. Milk composition based on one test milking was not reliable. Milk yield as estimated in any month was highly related to calf average daily gain from birth to weaning. Use of two test milkings improved the relationship only slightly. Milk solid component percentages showed little relationship to calf gains.

Dehulled, low-erucic acid–low-glucosinolate, full-fat rapeseed (FFRS), was studied as a protein source in milk replacers for lambs. Before being incorporated into the milk replacers to provide 25% (FFRS-25) or 50% (FFRS-50) of the total dietary protein, the FFRS was either passed through a colloid mill (milled) or left unmilled. When compared with an all-milk protein diet (FFRS-0), inclusion of the unmilled FFRS decreased the digestibilities of dry matter, nitrogen and energy (P < 0.01). Addition of unmilled FFRS to the milk replacer also decreased N retention (P < 0.01), but did not affect average daily gain. Addition of the milled FFRS to the milk replacers resulted in higher digestibilities of dry matter, nitrogen and energy and better retention of nitrogen than when the unmilled FFRS was added. However, the colloid-milled FFRS diet still was not as highly digestible as the all-milk diet. Increasing the level of substitution with milled FFRS from 25 to 50% produced a further decrease of about 4 units in the digestion coefficients and of 9 units in the retention of nitrogen expressed as a percent of the intake. Serum cholesterol levels just prior to and 2 h after feeding were not affected by the dietary treatments. Histology of liver biopsy samples taken at 22 days of age and of hearts and livers at market weight showed no detrimental effect on these organs from feeding low-erucic acid, low-glucosinolate FFRS to lambs. Based on growth trials it is concluded that low-erucic acid, low-glucosinolate FFRS, after colloid milling, can replace from 25 to 50% of the milk protein and most of the fat in lamb milk replacers without significantly affecting animal performance.
