Digestibility and N-retention were determined with eight barrows fed rye and barley in a crossover experiment. Dry matter and crude protein digestibility coefficients for rye were higher than those for barley, but differences in N-retention were negligible. The coefficients obtained by indirect measurement were higher than those determined directly. Seventy-two pigs were used in a factorial experiment to determine the effect on production of feeding two grades of rye at 0, 30 and 60% of pelleted and non-pelleted finisher rations. Weight gains by barrows compared with gilts were affected less by the addition of rye to the rations. The growth rate of gilts was reduced by the inclusion of 30% rye in non-pelleted but not in pelleted rations. The use of No. 2 grade rye appeared to have restricted rate of gain less than did No. 3 grade rye. The feeding value of rye was improved by pelleting, since the daily gain of 0.75 kg obtained by feeding a 30% rye, pelleted ration equalled that from pigs fed a 0% rye, non-pelleted ration.

Potato steam peel is a by-product of the production of frozen french fry potatoes. As produced, it typically has 14% dry matter with 15% crude protein and 6% ash (dry matter basis) and a pH of 5.8. The starch is partially denatured and there is no proteolytic enzyme inhibitor activity. The feeding value of steam peel for pigs was evaluated through chemical analyses, a digestibility trial and a feeding trial. Its digestibility (%) by pigs was found to be dry matter 81.1 ± 2.8, crude protein 61.3 ± 3.7, organic matter 82.4 ± 3.0 and energy 76.8 ± 6.0. In the feeding trial carried out on a commercial hog finishing farm, feed consumption was markedly reduced when the steam peel was included at over 30% of the ration dry matter at the start of the trial. The inclusion of steam peel at 15, 20 or 25% of the ration dry matter reduced the average daily gain and feed efficiency (P < 0.05). However, it was concluded that potato steam peel can be used at up to 25% of the diet for growing fattening pigs with little detrimental effect on the level of animal performance.

ABSTRACTFour diets containing 9·6 MJ metabolizable energy (ME) per kg dry matter (DM) (LMEC), and four diets containing 11·3 MJ/kg DM (HMEC) were formulated. One diet of each ME concentration contained 90 g crude protein (CP) per kg DM and served as a negative control (NC). In the three other diets of each ME concentration, the level of CP was raised to 140 g/kg DM by inclusion of poultry litter (PL), non-protein nitrogen (NPN) or fish meal (FM). These diets were examined in a digestion and N balance trial and in a feeding trial.For the NC, PL, NPN and FM subtreatments of the LMEC diets, DM intakes were 107·1, 112·4, 100·6 and 130·2 g/kg M075 respectively; digestibility coefficients of organic matter (OM) were 0·64, 0·70, 0·67 and 0·71 respectively; and N retention 0·40, 0·76, 0·53 and 1·21 g/kg M075 respectively. For the respective subtreatments of the HMEC diets, the values were: 100·4, 119·4, 109·3, 107·5 for DM intake; 0·64, 0·73, 0·73, 0·73 for digestibility coefficients of OM and 0·40, 0·87, 1·06 and 1·03 g/kg M075 for N retention.Daily gain on the respective diets in the first 130 days of the feeding trial was 0·85, 0·90, 0·91, 1·04 kg for the LMEC and 1·09, 1·21, 119, 1·24 kg for the HMEC diets, and from the 131st day to slaughter was 0·98, 1·02, 100, 1·08 kg for the LMEC and 1·03, 1·02, 1·07, 1·05 kg for the HMEC diets respectively. Daily carcass gain was 0·49, 0·51, 0·51, 0·53 kg for the LMEC and 0·55, 0·59, 0·59, 0·60 kg for the HMEC diets, respectively.The relationship between ME concentration in the diet and source of CP is discussed.

Rice whole stillage (RWS) is disposed to aerobic spoilage when stored for a prolonged period. The objectives of the present study were to evaluate the fermentation characteristics of ensiled RWS with wheat straw (WS) and wheat bran (WB) inoculated with Amylomyces rouxii, as well as to evaluate their impact on the metabolic profiles and the growth performance in Japanese black steers. Ensiled blends containing RWS, WS and WB were prepared either with A. rouxii inoculation (AS) or without (US). Fifteen silo bags were made for each blend; each bag had a width × height of 110 × 110 cm. The silos were analysed on Days 0, 7, 14, 28, 42 and 60 after ensiling. Notably, crude protein concentrations were found to be higher in the US treatment than in the AS treatment. In contrast, ash and acetic acid concentrations were elevated in the AS treatment compared with the US treatment. Lactic acid (LA) concentrations did not differ between the two treatments. Furthermore, the feeding efficacies of the prepared silages were evaluated as a feeding material for Japanese black steers. Control diets were composed of total mixed ration (TMR) and timothy hay, and the test diets were composed of TMR supplemented with either 1 kg/head.day US silage blend (USTMR) or 1 kg/head.day AS silage blend (ASTMR). Steers fed on the ASTMR diet exhibited a decrease in blood LA concentrations compared with the other groups. Moreover, growth performance revealed that daily gain and final bodyweight values were similar among treatments. Collectively, RWS can be effectively ensiled with or without A. rouxii and used as a feedstuff for maintaining an adequate growth rate of steers.

Twelve wether sheep were used in a 2 x 2 factorial experiment in which voluntary intake, diet digestibility, and eating and ruminating behaviour were compared when sheep were offered lucerne (Medicago sativa) as either wilted silage or hay. Chemical characteristics suggested that the lucerne silage was well fermented, and chemical compositions of the silage and hay were similar. Voluntary intakes were not significantly (P<0.05) different and were 1201 and 1220 g/day for silage and hay, respectively. Digestibilities of dry matter and organic matter were similar for both feeds, as were chewing behaviour and rumen physical function. Apparent crude protein digestibility was significantly (P<0.05) higher for silage than for hay (73.8 v. 70.3%). It was concluded that well-preserved lucerne silage has at least as high a feeding value as well-made lucerne hay.

A feeding trial and two digestibility trials were conducted to evaluate two isogenic lines of regular (covered) and hulless barley, cvs. Compana and Vantage, compared also with wheat. Eight pigs (4♀, 4♂) were fed each diet over the weight range 22–50 kg. Half of the pigs, randomly selected within sex and diet groups, were used in the digestibility trials, employing chromic oxide markers. The second digestibility trial involved different pigs from the first and a new source of hulless barley. The average daily gain was 0.62 kg and there were no significant differences between rations. Likewise, feed intakes and efficiencies of feed conversion revealed no treatment differences. The digestibility of protein in hulless barley was lower than in regular barley (70 vs. 73% in one trial, 74.8 vs. 79.3% in another) and both types of barley were lower in protein digestibility than wheat (81.4%). Energy digestibility was highest in hulless barleys (77.3 vs. 73.2; 81.8 vs. 77.1%). Hulless barley contained about 5% more digestible energy than regular barley (3,295 vs. 3,133 kcal/kg) and the same digestible crude protein (12.85 vs. 12.90%).

AbstractThe nutritional value of different categories of peas was measured in mash or pelleted diets using adult cockerels. Twenty-five round and white-flowered peas (feed peas), 12 round and coloured-flowered peas and five wrinkled and white-flowered peas were used in mash diets. From the same batches, 11 feed peas, five coloured peas and four wrinkled peas were tested in pelleted diets.Mean apparent metabolizable energy (AME) values were 12·02, 11·35 and 10·50 MJ/kg dry matter (DM) for feed peas, coloured peas and wrinkled peas respectively in mash diets and 13·18, 12·72 and 11·63 MJ/kg DM for the same categories in pelleted diets.Mean starch digestibility was 0·905, 0·887 and 0·802 for feed peas, coloured peas and wrinkled peas respectively in mash diets and 0·985, 0·984 and 0·840 for these categories in pelleted diets.Mean protein digestibility was 0·788, 0·643 and 0·798 for feed peas, coloured peas and wrinkled peas respectively in mash diets and corresponding values for peas in pelleted diets were 0·855, 0·743 and 0·853.Pelleting thus had a positive effect on the nutritional value of peas and this improvement was all the more important because the AME and protein digestibility of the pea in mash diets was low.The nutritional value of feed peas for cockerels was not strongly correlated with chemical composition or to digestibility data obtained in the pig.

Treatment of oilseed meals with formaldehyde (FA) and glutaraldehyde (GA) significantly (P < 0.01) reduced the solubility of protein in 0.02 N NaOH and the production of NH3 in the artificial rumen. Ten Holstein and Holstein × Brown Swiss calves of both sexes were fed two test rations containing either 26% untreated or formaldehyde-treated (5.6 g FA per 100 g protein) rapeseed meal (FA-treated RSM) for 14 weeks. Plasma urea nitrogen (N) and rumen NH3 levels were significantly (P < 0.01) lower in the FA-treated RSM calves compared with the control calves during the first 8 weeks of the growth trial. No significant difference (P > 0.05) in dry matter consumption, daily gain, or feed efficiency was observed. Total volatile fatty acids (VFA) (mmoles/100 ml) concentration was significantly higher (P < 0.05) in rumen fluid from the control calves compared with those receiving treated RSM. Molar percentages of the VFA’s were not significantly different (P > 0.05) between the two groups. In the N balance and digestibility trial, dry matter consumption did not differ significantly (P > 0.05); however, the FA-treated RSM resulted in decreased (P < 0.05) dry matter and crude protein digestibility. Calves receiving the treated RSM had reduced (P < 0.01) urinary N excretion; however, there was no significant effect (P > 0.05) on N consumption and retention.

1. An experiment was carried out in which protein utilization in the pregnant ewe was studied using the nitrogen balance technique.2. Eight diets supplying four different intakes of crude protein and two different intakes of energy were each offered to eight individually penned ewes.3. The mean crude protein intakes per day were 7·2, 5·5, 4·1 and 3·0 g/kg W0·73 (where W = body-weight) and the metabolizable energy intakes 134 and 113 kcal/kg W0·73.4. N balances were carried out at 10–12, 14–16 and 18–20 weeks of gestation on five ewes from each treatment.5. The apparent digestibility of both dry matter and crude protein decreased with decreasing protein intake. With the high energy intake, the apparent dry-matter digestibility was increased and the apparent digestibility of crude protein decreased. Stage of gestation had no significant effect on the apparent digestibility of either of these constituents.6. N retention was not affected by the number of foetuses carried. With the higher energy intake and the higher protein intakes, the absolute retention of N was significantly increased at all stages of gestation. N retention increased with advancing pregnancy; the retentions at 10–12, 14–16 and 18–20 weeks of gestation being 0·086, 0·114 and 0·163 g/kg W0·73 per day respectively.7. The efficiency of utilization of apparently digested N was calculated from the regression of retained N as a percentage of apparently digested N against apparently digested N.8. The daily intakes of apparently digested N required for maximum efficiency were 0·551 and 0·620 g/kg W0·73 on the high and low energy intakes respectively. The daily intake for maximum efficiency decreased with advancing pregnancy, the values being 0·623, 0·587 and 0·567 g/kg W0·73 for the 10–12, 14–16 and 18–20 weeks of gestation respectively.9. The levels of N retained at maximum efficiency were 0·235 and 0·202 g/kg W0·73 per day for the high and low energy intakes respectively. The levels of N retained increased during pregnancy from 0·170 g/kg W0·73 per day at 10–12 weeks to 0·286 g/kg W0·73 at 18–20 weeks. The requirements for zero N balance were 0·072 and 0·153 g apparently digested N/kg W0·73 per day for the high and low energy intakes respectively. The requirement for zero N balance decreased from 0·176 g/kg W0·73 per day at 10–12 weeks to 0·071 g/kg W0·73 at 18–20 weeks.10. The results are discussed in relation to other research findings and current recommendations.

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.

ABSTRACTNinety-six Hereford steer calves that weighed 249(s.e.4·7)kg were allocated randomly to four treatments of 24 steers each in a randomized complete block design with four blocks. The steers grazed dormant native range forage that contained 41 to 60 g of crude protein per kg dry matter during the 120-day wintering trial and were given 0·91 kg of supplement per head per day. The supplements used contained 175 or 350 g crude protein per kg dry matter and 0 or 165 mg monensin per kg supplement; a factorial arrangement of treatments was used in allocating the supplements. Weight gains of steers given the high-protein supplements were greater than those on the low-protein supplements during periods 1(0 to 61 days) and 2 (62 to 120 days), and over the total trial (P < 0·01). Monensin increased weight gains during period 1 and the total trial (P < 0·01). The protein level × monensin interaction was not significant for either period or the total trial (P > 0·15). The results indicate that inclusion of monensin in protein supplements for growing cattle grazed on low-quality dormant native forage may allow some reduction in protein content of the supplement.
