It is common practice for feed barley to be purchased on sample specific weight. It can be argued that this historic measurement may give a misleading indication of its energy and feeding value. If this were to be true, then 6-row barleys which have a number of agronomic advantages, including high yields, could be discriminated against when compared to the more common 2-row barleys. Manitou is such a 6-row barley, which has out-yielded the best performing 2-row varieties by 6% in England (NIAB Recommended List 1991), and by 28% in Scotland (Scotland Agricultural Colleges Recommended List 1991). Trials were undertaken to compare Manitou and Marinka (2-row barley) at similar thousand grain weights (TGW), but different specific weights (sp.wt), with growing and finishing pigs.

Potato steam peel (SP) is a by-product of potato processing where the peel is removed after steaming. It typically contains 15 ± 3% dry matter, 16 ± 1% crude protein, 0.55 ±.05% lysine, 0% methionine/cystine and 6% ash (dry matter basis). Steaming effectively deactivates the proteolytic enzyme inhibitors and partially denatures the starch. SP was evaluated in a digestibility trial and at levels from 0 to 30% DM in two feeding trials. The digestibility (%) of SP by pigs was found to be 88.4 (DM), 80.1 (CP) and 86.1 (DE). In the first feeding trial diets containing levels of 0, 10, 15, 20, 25 and 30% SP supplemented with methionine resulted in similar growth performance and carcass characteristics. In the second feeding trial, a comparison was made between a constant level of inclusion and an increase in inclusion level with age. Results showed no difference in growth performance or feed consumption among treatments. It is concluded that SP can be incorporated in diets for growing-finishing pigs at levels up to 30% DM. No change in performance resulted from increasing level of inclusion with age. Key words: Potato, steam peel, pigs, digestibility

High moisture (HM) shelled corn (66.7% dry matter), preserved with 1.5% propionic acid, was fed as a part of the ration to 12 lactating dairy cows, seven growing dairy heifers, and 20 growing-finishing pigs. HM ensiled, shelled corn was fed to similar groups as a comparison. In addition, a third group of 12 cows received a commercial dairy supplement. Fat-corrected milk yield, persistency of milk production, milk fat and protein percentage, and rate of gain by dairy heifers were not significantly different between rations when HM corn was fed at 4.5 kg/animal/day. Average daily gains by pigs whose ration comprised 70% treated grain corn versus 70% ensiled grain corn were 0.70 and 0.63 kg (P < 0.01). A nonsignificant improvement in feed efficiency was observed by heifers and pigs fed treated grain corn. Mold counts were 0 and 1200 colonies/g for treated and ensiled grain corn. There was no adverse effect of propionic acid treatment upon animal health or performance. The relationship between dietary propionic acid and synthesis of milk fat, milk protein and tissue protein are discussed.

Dried potato pulp (molassed) was fed to growing pigs to replace barley and to finishing pigs to replace oats in the rations. Levels of 0, 15, 30 and 45 per cent potato pulp, in place of barley, were tested with pigs from weaning to market weight. Although 22 per cent potato pulp in a growing ration reduced (P < 0.05) the rate of liveweight gain, results indicated that up to 15 per cent potato pulp allowed satisfactory gains.The replacement of oats by potato pulp in a finisher ration gave an increased rate of gain which was not statistically significant. A level of 30 per cent potato pulp in growing-finishing rations gave lower (P < 0.01 and 0.05 respectively) rates of gain than did the zero and 15 per cent level. Feed efficiency was reduced significantly by all levels of potato pulp fed through the growing-finishing period. Potato pulp appeared to influence "fill" as reflected in lower dressing percentages based on liveweight at marketing. Compared with the controls, 45 per cent potato pulp reduced (P < 0.05) depth of shoulder and loin fat. Coefficients of apparent digestibility for potato pulp dry matter, crude fiber and energy were 81, 75, and 76 per cent respectively; but the crude protein, approximately 7 per cent of the dry matter, was only 25 per cent digestible. This finding emphasized the need for protein supplementation of pig rations containing potato pulp.
