Abstract A two-yr study was conducted to evaluate the effects of monensin on sparing ruminal degradable protein in yearling steers grazing smooth bromegrass pastures (n = 288, initial BW = 332 kg, SD = 7). Treatment design was a 2 x 3 factorial with the following factors: 1) 0 or 200 mg monensin/steer daily; 2) no protein supplement, 1.25 kg soybean meal (SBM) as a source of RDP, or 1.31 kg non-enzymatically browned SBM as a source of RUP. Steers receiving supplemental protein were provided isonitrogenous amounts equivalent to dried distillers grains plus solubles at 0.50% BW. Steers were weighed approximately every 34 d to adjusted the amount of protein supplement. There was no interaction (P > 0.41) of monensin by protein type for average daily gain (ADG). Rate of gain for steers supplemented monensin was not different (P = 0.26) from steers not supplemented monensin. However, monensin supplemented steers numerically gained 7.9% more than steers not provided monensin when no supplemental protein was provided. Compared to steers supplemented with no protein, supplementing RDP increased ADG by 0.19 kg/steer (P < 0.001). Likewise, RUP supplementation increased ADG by 0.24 kg/steer (P < 0.001) compared to steers supplemented no protein. Supplementing RUP increased ADG by 0.05 kg/steer (P < 0.001) compared to steers supplemented RDP. Supplementing protein, especially rumen undegradable protein, improved yearling steer rate of gain on smooth bromegrass pastures. Monensin supplementation did not improve rate of gain. These data do not support the protein-sparing effects of monensin for steers supplemented with RDP.

Abstract Objectives were to compare feedlot performance and carcass traits of F1 beef × Holstein steers and Holstein steers. Angus or Limousin × Holstein crossbred [n = 27; age = 12 ± 3 months; body weight (BW) = 435 ± 8 kg] and Holstein (n = 20; age = 11 ± 2 months; BW = 400 ± 9 kg) steers were fed at the Pennsylvania Department of Agriculture Livestock Evaluation Center for 111 days. Feed intake was recorded using the GrowSafe Feed Intake Monitoring System (Model 4000E, GrowSafe Systems Ltd., Calgary AB, Canada). The diet contained corn silage, dried distillers grains, soybean meal, and cracked corn and was formulated to meet or exceed the requirements of beef cattle (NASEM, 2016). Growth performance variables of interest and carcass measurements were analyzed with the Mixed procedure of SAS (SAS 9.4; SAS Institute Inc., Cary, NC). USDA assigned quality grades (QG) and yield grades (YG) were analyzed the with GLIMMIX procedure of SAS. Breed was a fixed effect in all models. There were no differences (P > 0.05) between breeds in average daily gain or feed efficiency. Crossbreds exceeded Holsteins in initial (P < 0.01) and final BW (P = 0.01), dry matter intake (P = 0.03), hot carcass weight (P < 0.01), backfat (P = 0.03), and ribeye area (REA; P < 0.01). Thirty-five percent (35%) of the Holsteins received a QG of Choice or above while 74% of crossbreds graded USDA Choice or above (P = 0.01). However, 75% of Holsteins were YG 2 or lower while only 45% of crossbreds achieved YG 2 or less (P = 0.05). There was no improvement in efficiency when crossbreds were compared to Holsteins; however, carcasses from crossbreds were more likely to grade USDA Choice or above while yielding greater REA and backfat than Holsteins.

AbstractThe present study evaluated the interaction effects of n-3 fatty acids (from linseed oil (LSO), 0 v. 2·5, % DM basis) with rumen undegradable:degradable protein (RUP:RDP) ratios (low ratio (LR) 27:73; high ratio (HR) 38:62 based on crude protein %) in dairy calves’ starter diet. Forty-eight 3-d-old female Holstein dairy calves (41·5 kg of body weight (BW)) were allocated in a 2 × 2 factorial arrangements in the following treatments (n 12 calves/each): (1) no supplementation of LSO with LR (NLSO-LR); (2) no supplementation of LSO with HR (NLSO-HR); (3) supplementation of LSO with LR (LSO-LR) and (4) supplementation of LSO with HR (LSO-HR). The calves were weaned on day 53 of the experiment and remained in the study until day 73. Intake was not affected by LSO and RUP:RDP ratio. However, average daily gain (ADG) was improved with LSO supplementation. Feeding the HR diet increased ADG compared with the LR diet during the entire period. Final BW was greater in calves fed on the LSO than those fed the NLSO diet. Microbial protein production did not differ among treatments. Calves fed on LSO diets had greater feed efficiency than those which were not fed on LSO diets. The calves supplemented with LSO had greater wither and hip heights compared with the unsupplemented calves. The glucose, cholesterol, HDL and insulin concentrations increased in calves supplemented with LSO. In conclusion, the HR diet improved calves’ performance post-weaning; however, LSO could enhance growth performance of dairy calves during the pre-weaning period.

Growth Experiments

An experiment was undertaken to determine the effect of lignosulfonate (LSO3) treatment on the rumen-undegradable protein (RUDP) value of canola meal (CM) and soybean meal (SM). Canola meal and SM were treated with 7% LSO3 and heated (95 °C) for 1 h. Treated and untreated meals were compared in vitro, in situ and in digestibility and growth experiments using Romanov × Suffolk and Romanov × Dorset lambs. Lambs were fed four barley-based diets [13.5% crude protein (CP)] with one of CM, SM, LSO3-treated CM (LSO3-CM) or LSO3-treated SM (LSO3-SM) as protein supplements. Lignosulfonate treatment increased acid detergent insoluble nitrogen (ADIN) five-fold in SM and threefold in CM. After 6 h incubation with ruminal fluid, ammonia production from LSO3-treated meals was one-half that from untreated meals. Lignosulfonate treatment reduced (P < 0.01) in situ rates of dry matter (DM) and protein disappearance and the soluble DM and protein fractions for both SM and CM, but not the potentially digestible fractions. No differences in feed conversion or average daily gain (P > 0.05) were found among the treatments. Although LSO3 treatment did not improve the ADG of lambs fed barley-based diets, it increased the RUDP value of SM and CM without adverse effects on digestibility.

Results of the study of the effect of the level of nondegradable protein in diet on fattening performance and digestibility of nutrients in weaned lambs are presented in the paper. Objective of the study was to establish the optimal level of non-degradable protein in diets for weaned and intensively fattened lambs. Experiment was conducted on 60 lambs of F1 generation: Pirot Pramenka x Wurttemberg x Ile de France, weaned at the age of 60 days and divided into three groups. The effect of use of three concentrated mixtures which differed in the share of protein non-degradable at the level of rumen: 43% (I), 51% (II) and 58% (III). Average daily gain of lambs fed types of mixtures I:II:III was 0.169: 0.205 : 0.227 kg, respectively. Dry matter conversion (kg/kg of gain) on analogue treatments was: 4.54 : 3.71: 3.30, respectively, of energy (MJ NEM/kg) : 33.77: 29.37 : 26.25, and of total proteins (g/kg): 732 : 596 : 549. Level of intake of proteins was not influenced by the treatment considering that the digestibility coefficients recorded were: 52.58% : 51.30% : 55.12%. With the increase of the share of non-degradable protein in concentrate mixtures, the tendency of increase of the digestibility of fat was present: 76.13 : 77.98 : 87.17%, as well as of decrease of the intake of fibre: 67.40 : 45.87: 22.39% and NFE: 83.87 : 76.05 : 82.96%. Values of the dressing percentage of warm carcass with giblets according to nutrition types I:II:III were: 58.70 : 58.02 : 57.42%, respectively.

Basal Ration

Sixty-three Hereford steer calves were used in a feeding trial which comparade a simple basal grain ration [11.7 per cent total crude protein (TCP)] with the basal grain ration supplemented with either whale solubles (16.3 per cent TCP) or linseed meal (15.3 per cent TCP) to determine whether whale solubles could replace linseed meal as a source of protein in steer finishing rations. Forage (mixed grass-legume hay and grass-legume silage) and grain were fed in a ratio of approximately 1:1.25.Results for steers fed the basal ration, basal plus whale solubles and basal plus linseed meal were: average daily gain— 1.68, 1.72, 1.85; pounds of total digestible nutrients per pound of gain — 5.5, 5.4, 5.2; dressing percentage — 58.5, 58.7, 59.1; and per cent lean in rib-cut at last rib — 64.6, 65.5, 67.8.Steers fed the basal ration plus linseed meal gained significantly more (P < 0.05) and required less feed per pound of gain than those fed either the basal ration or the basal ration plus whale solubles. Differences between groups for the other measured characteristics were not significant (P = 0.05). Carcasses of steers fed the basal ration or basal plus whale solubles graded slightly higher than those of steers fed the basal ration plus linseed meal.Whale solubles did not equal linseed meal as a source of supplemental protein for finishing steer calves under the conditions of this experiment.

In a 55-d backgrounding period, 120 (n = 22) British cross heifers (312 ± 20 kg) received diets containing 55% barley silage, 5% supplement and 0 (n = 24), 20 (n = 24), or 40% (n = 22) wheat distillers’ dried grains with solubles (DDGS). The remainder of the diet was steam-rolled barley. Replacing half (20%) or all (40%) of the barley with DDGS did not affect dry matter intake (DMI) (P = 0.61), average daily gain (ADG) (P = 0.86), or gain:feed (P = 0.94), indicating the energy content of DDGS is similar to that of barley when included in backgrounding diets. During a 133-d finishing period, DDGS were included at 0, 20, 40, or 60% of diet dry matter (DM) or at 60% plus additional calcium, provided as 1% limestone (n = 24). Additional calcium did not (P > 0.1) affect DMI, ADG, or gain:feed. Increasing levels of DDGS linearly increased (P = 0.001) DMI and reduced (P = 0.04) gain:feed and diet NEg content (P = 0.001), but had no effect on ADG (P = 0.20). Feeding 60% DDGS reduced (P < 0.01) DM digestibility as compared with the control. Wheat DDGS has similar feeding value as barley when included at 20% of diet DM, but digestibility and energy content decline with higher levels of inclusion.

Two experiments were conducted to evaluate the replacement value of canola meal (CM) for soybean meal (SBM) in isoenergetic isonitrogenous diets for young pigs between 6 and 20 kg liveweight. Diets utilized wheat, barley, oat groats and blended animal fat as energy sources and evaluated CM at levels from 0 to 100% replacement of SBM. Regression analyses of the results of both experiments indicated that for every 1% addition of CM in the diet, there was a corresponding decrease in average daily feed intake (ADF) and average daily gain (ADG) of 4 and 2 g, respectively. Digestibility coefficients of dry matter and nitrogen were not significantly affected by the level of CM in the diet. Key words: Starter pig, canola meal, soybean meal, protein supplement

The objective was to determine the effect of low inclusion levels of dried distillers grains (DDG) on feeding behavior in heifers consuming a high-moisture corn-based diet in the finishing phase. Simmental × Angus heifers (N = 90; 323 ± 50 kg) were fed for 180 d. Heifers were blocked by initial body weight (BW) into two groups, stratified by sire, and assigned to 15 pens with six heifers each. Pens were randomly assigned to one of three dietary treatments: 0% DDG inclusion (0DG), 7% DDG inclusion (7DG), or 14% DDG inclusion (14DG). Treatments did not affect (p > 0.59) BW, average daily gain, and gain:feed. Although there was a treatment × time effect (p = 0.05) for dry matter intake (DMI), with 0DG having greater DMI during the last 70 d, no differences in overall DMI were detected. Treatment affected (p < 0.01) bunk visit duration and head down duration, with 7DG and 14DG having less minutes per day. Bunk visit frequency (p = 0.02) was less variable for heifers fed 14DG and DMI tended (p = 0.08) to be less variable for both distillers treatments. While dietary inclusion of DDG has minimal effects on overall heifer performance, low levels of DDG inclusion can affect feeding behavior and intake variation.
