Grass-red clover silage was fed ad libitum. In experiment 1 a duplicated 4 x 4 Latin square design was used. A mixture of oats and barley was given at 8 kg (C). Three isonitrogenous protein supplements were a commercial rapeseed meal (218 g kg-1 dry matter (DM); RSM), crushed organic field pea (Pisum sativum L.) (452 g kg-1 DM; P) and a mixture of pea (321 g kg-1 DM) and organic rapeseed (Spring turnip rape, Brassica rapa L. oleifera subv. annua) (155 g kg-1 DM; PRS). Cows on P and PRS diets produced as much milk as cows on the RSM diet. Milk yield was higher but protein content lower with PRS diet than with diet P. In experiment 2 a triplicated 3 x 3 Latin square design was used. A mixture of oats (395 g kg-1 ), barley (395 g kg-1 ) and a commercial heat-moisture treated rapeseed cake (210 g kg-1 ) was given at 8 kg (RSC). The second diet (ORSC) consisted (g kg-1) of oats (375), barley (375) and cold-pressed organic rapeseed cake (250). The third diet (RSCO) consisted (g kg-1) of oat (395), barley (395) and commercial heat-moisture treated rapeseed cake (250) and additional rapeseed oil (0.38 kg) to balance fat content between ORSC and RSCO diets. There was no dietary effect on the yield of energy corrected milk. Milk yield was higher with RSCO diet compared with other diets.;

Twenty Friesian cows in four pens were arranged in a 4 x 4 Latin square experiment with 4 wk experimental periods to evaluate the effects on feed intake, milk yield and milk composition of treating barley dried distiller’s solubles (DDS) with a formaldehyde reagent, and to compare DDS with rapeseed meal as a protein supplement in dairy cows given a grass silage-based diet. The control diet (C) consisted of grass silage ad libitum fed with 8.5 kg/d of concentrate based on barley, oats and barley fibre (250, 250 and 500 g/kg dry matter (DM)). In three other diets 1.5 kg/d of the basal concentrate was replaced with rapeseed meal (RSM) treated for reduced ruminal degradability, 1.5 kg of untreated DDS (UDDS) or 1.5 kg of DDS treated with formaldehyde reagent at the level of 15 l/t (TDDS). On average, protein supplementation increased silage and total DM intake by approximately 0.5 kg/d (P>0.05). Milk yield (P

Sixteen lactating Holstein cows were randomly assigned to treatment sequences in a 4 × 4 changeover experiment. Experimental periods were 28 days in length separated by 7 days for changeover. Cows were fed corn silage free choice and gradually increasing amounts of one of four dairy concentrates containing 0, 11, 22, or 34% rapeseed meal (RSM) of a Canadian, experimental, low glucosinolate–low erucic acid variety. Concentrate intake (kg dry matter/day), milk yield (kg/day) and body weight change (kg/28 days) were 8.45a, 8.71a, 8.37a and 7.17b; 24.40a, 24.03ab, 22.92bc and 21.96c and 7.6b, 22.4b, 13.0ab, and 3.0b for 0, 11, 22 and 34% RSM mixtures, respectively. There was no influence of treatment on milk composition. Ration dry matter (DM) and nitrogen digestibilities declined (P < 0.05) as the RSM in the concentrate mixture increased. The amount of nitrogen excreted in the urine was greatest for cows fed 0% RSM and least for cows fed 34% RSM. Cows fed concentrate mixtures containing 34% RSM had a lower blood thyroxine level than others (P < 0.05), but RSM-containing concentrates had no apparent effect on the conversion of thyroxine to triiodothyronine. Results of the trial indicated that this experimental variety of RSM had no detrimental effect on concentrate intake, DM digestibility, milk composition or thyroid hormone metabolism when included at levels up to 22% in the concentrate mixture. However, milk yield and apparent digestibility of ration nitrogen were decreased (P < 0.05) by the 22% RSM mixture. It was not certain from the current findings whether the depression in digestibility was due largely to the high oil content of the meal or due to the higher fiber content of the RSM-supplemented rations.

1. Six 45 kg pigs with re-entrant ileal cannulas were used in two 3 × 3 Latin-square design experiments to study the site of absorption of protein and amino acids. Semi-purified diets containing soya-bean meal (SBM), rapeseed meal (RSM) or no protein source (protein-free) were offered at the rate of 1 kg dry matter/d.2. Flow-rates of ileal contents for 24 h collection periods, corrected for recovery of marker, were 3135, 3127 and 1243 ml (SE 390) for SBM, RSM and protein-free diets respectively.3. Amounts of dry matter digested in the small intestine were 730, 669 and 809 g/d for SBM, RSM and protein-free diets respectively, all values being significantly different (P < 0·001).4. Nitrogen intakes were 32·6, 29·9 and 5·9 g/d, and amounts digested in the small intestine were 25·7, 20·2 and 1·6 g/d for SBM, RSM and protein-free diets respectively, all values being significantly different (P < 0·001). Amounts digested in the large intestine were 2·6, 3·7 and 0·7 g/d.5. Total amino acid intakes and amounts collected at the ileum and in the faeces were (g/d): SBM, 177, 24 and 18; RSM, 149, 28 and 22; protein-free 3, 9 and 12. Digestibility in the small intestine was higher for SBM than RSM for seventeen of the eighteen amino acids estimated. Greater quantities of arginine, methionine, cystine and tyrosine were voided in the faeces than passed through the ileal cannulas for pigs receiving the SBM and RSM diets. For those receiving the protein-free diet this was true for each amino acid except proline.6. Significant differences were found between all diets in the concentration of some amino acids in ileal and faecal amino-N, and endogenous protein secretions did not mask the differences between diets.7. Differences in digestibility between SBM and RSM were greater at the ileum than in the faeces. Amino acid fermentation in the large intestine obscured or reduced differences between SBM and RSM.

N Yield

The authors have evaluated the development and the quality of timothy and bromegrass grown alone and in mixtures with either alfalfa or red clover. Nitrogen-fertilized grasses yielded on the average more dry matter than their mixture counterpart. Either of the grasses with red clover contributed more evenly to yield than with alfalfa. The highest yield of protein was obtained from the association of alfalfa with timothy or bromegrass whereas these grasses were the poorest protein yielders even with 72–90 kg/ha of applied N. Yield contribution of timothy and bromegrass in mixture with either legume increased over the first two harvest years; timothy, however, maintained this trend through the third year while bromegrass reached an equilibrium or decreased. From a roughage quality stand-point a binary mixture of the grasses with alfalfa is the best, followed by the grasses with red clover and finally, the grasses in pure stand.

Two experiments were conducted to evaluate rapeseed meal (RSM) produced from seed of Brassica campestris L. ’Candle’ in comparison with B. napus L. ’Tower’, soybean meal and fababeans (Vicia faba) as protein supplements for growing swine. In experiment 1 Candle RSM (5, 10 or 15%) was substituted for soybean meal or fababeans in barley- and wheat-based diets for 120 pigs from 23 to 88 kg liveweight. The effects of supplementary iodine (0.14 mg I/kg diet) and amino acids (0.15% lysine and 0.05% methionine) on the nutritive value of Candle RSM were also studied. The results of experiment 1 indicated that daily feed intake and carcass value index were not significantly (P > 0.05) affected by diets. The growth and feed utilization responses of pigs fed diets which contained soybean meal and fababeans as the sole source of supplementary protein were similar and the replacement of these protein supplements with Candle RSM, unless supplemented with amino acids, resulted in a reduction in rate of growth and efficiency of feed utilization. Gains adjusted by regression for feed intake variations showed benefit from lysine. Diets containing 15 % of either Candle or Tower RSM, plus lysine, were utilized about 95% as efficiently as soybean meal diets. Supplementation with iodine produced no significant response. The digestibility coefficients of the protein and energy of Candle RSM and soybean meal were determined in experiment 2. The apparent digestibility of protein in Candle RSM was 81% and energy digestibility was 71%. The digestible energy content was 14.12 MJ/kg (3370 kcal/kg), dry matter basis.

AbstractHigh digestibility ryegrass was ensiled using either good methods including formic acid application (HDG) or poor methods without formic acid (HDP). Low digestibility ryegrass (LDG) and lucerne (LUC) were ensiled using similar methods to HDG. Digestible organic matter in the dry matter (DM) in vivo (DOMD) for HDG, HDP, LDG and LUC were 0·756, 0·774, 0·645 and 0·562 respectively. Silages were offered ad libitum to 40 HolsteinFriesian cows in two Latin-square design experiments during weeks 8 to 22 of lactation either alone (experiment 1) or with 3, 6, 9 or 12 kg concentrate DM per day (experiment 2). Relative intakes of silage given alone were respectively 1·00, 0·44, 0·98 and 0·79. Low intake of HDP could not be predicted from silage analysis. In experiment 2, DM intake increased by 0·11 kg and milk yield by 0·24 kg for each 0·010 change in grass silage DOMD. Intake of HDG, LDG and LUC declined linearly with increasing concentrate, on HDP the effect was non-linear and intake increased up to the 6 kg level.In experiment 1, milk and protein yields were greatest on HDG, protein yield was higher on LDG than LUC and fat concentration higher on HDP and LUC. With supplementation milk yield was greatest on HDG up to the 6 kg level, at higher levels differences between silages were not significant. Fat concentration was highest on LDG and protein highest on HDG and lowest on LUC. On all silages giving the highest concentrate level reduced the concentration and yield of fat. Protein concentration increased up to the 9 kg level. Fat plus protein yields reached a maximum on HDG with 6 kg concentrate DM per day and with 9 kg on the remaining silages.

AbstractFour diets, barley/proprietary protein concentrate (B/PC), barley/maize gluten (B/MG), barley/rapeseed meal (B/RSM) and wheat/'rapeseed meal (W/RSM) were formulated to contain 165 g crude protein and 13·0 MJ metabolizable energy per kg dry matter. In experiment 1, all four diets were offered ad libitum to Charolais × Friesian bulls from 187 kg live weight to slaughter at about 488 kg live weight. In experiment 2, the B/PC and B/RSM were offered ad libitum to Charolais × (Hereford × Friesian) bulls from 222 kg live weight to slaughter at about 491 kg live weight. There were no significant differences between treatments in daily live-weight gain, percentage fat and lean in the live animal, slaughter weight or days on experiment in either experiment. In experiment 1, the carcasses from bulls given B/PC were 14 kg heavier than carcasses from bulls given W/RSM (P<0·05), but only 10 and 7 kg heavier than from bulls given B/MG and B/RSM respectively (P<0·05). The killing-out proportion of bulls given B/PC was significantly greater (P<0·05) than bulls given B/RSM. In experiment 2, carcass weights were similar but the killing-out proportion of bulls given B/PC were again greater (P < 0·001). It is concluded that B/MG and B/RSM were as effective as B/PC as finishing diets and that wheat can be successfully substituted for barley, when offered with rapeseed meal.

A duplicated 4 x 4 Latin Square experiment was conducted to determine the effects of a gradually increased level of barley fibre in the diet on ad libitum grass silage intake and milk production. Barley fibre is a fibrous ethanol-starch by-product (120 g crude protein, 550 g neutral detergent fibre (NDF) and 120 g starch/kg dry matter (DM)). The four supplements, given at the rate of 6.5 kg/d on DM basis, were barley (B) and barley of which 333 g/kg (BF), 667 g/kg (FB) and 1000 g/kg (F) were replaced by barley fibre. In addition the cows were given 1 kg of rapeseed meal and 0.25 kg of mineral mixture. As the proportion of barley fibre in the diet increased there was a linear (P

Trifolium Pratense L

The objective of this study was to investigate the changes that take place in nutrient values of red clover (Trifolium pratense L.) cv K-27 at different stages of growth in the second and the third cut. The samples from different stages of growth: mid-bud stage, around 60% flowering and full flowering were investigated for crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), digestible dry matter (DDM), dry matter intake (DMI), relative feed value (RFV), total digestible nutrients (TDN), net energy-lactation (NEl), net energy-maintenance (NEm) and net energy-gain (NEg) content. Higher content of crude protein was found in the third cut (262.1 g kg-1 of DM) than in the second cut (260.8 g kg-1 of DM) in the first stage of development. TDN, DDM, DMI, RFV, NEl, NEm and NEg were calculated according to the appropriate equations adapted from common formulas for forages. The stage of plant development has a significant influence on the chemical composition and the relative feed value of red clover. The achieved results show that adequate maturity stage for cutting might be at mid-bloom stage, when crude protein content, NEl, NEm and NEg content are high.
