Forty-eight lambs (29.0 ± 4.7 kg BW) were used to study the effects of protein supplementation of forages on performance and diet digestibility. Lambs were fed grass hay or silage ad libitum plus a daily supplement of either: C, a control supplement supplying 1.2 g kg−1 BW of dry molasses and 0.6 g kg−1 BW of minerals, vitamins and lasalocid; CM, control supplement + 5.48 g kg−1 BW of canola meal; or FM, control supplement + 3 g kg−1 BW of fish meal. Apparent digestibility of all dietary components was higher in lambs fed silage than in those fed hay (P < 0.04). Addition of CM or FM improved apparent digestibility of energy and crude protein (CP) of lambs fed hay (P < 0.02) and CP digestibility of lambs fed silage (P < 0.01). Apparent digestibility of CP was higher in lambs fed FM than in those fed CM with either hay or silage (P < 0.03). Addition of CM or FM tended to decrease ADF digestibility of silage-based diets (P < 0.06). Apparent ADF digestibility of hay-based diets was lower in lambs fed CM than in those fed FM (P < 0.02). Forage DM intake was similar for all treatments. Addition of CM or FM to the diets improved average daily gains by 24% (P < 0.03), an effect that was higher with hay (35.1%, P < 0.02). Feed efficiency was 23.6% better in lambs fed protein-supplemented hay than in those receiving C (P < 0.04). Neither dressing percentage nor carcass lean yield was affected by protein supplementation. Digestible DM and TDN intakes were higher in lambs fed silage (P < 0.03) as a result of higher apparent digestibility for silage than hay. Furthermore, CM increased TDN intake by 7.6 and 8.2% in lambs fed hay and silage, respectively, compared with lambs fed FM. Addition of canola and fish meals improved forage nutritive value for lambs. Key words: Canola meal, fish meal, forages, digestibility, lambs, growth

Two very low glucosinolate (VLG) canola meals from crop years 1987 and 1988 (CM; 1.66 and 0.53 μmol g−1) and two Tobin CM (B. campestris) (10.71 and 15.62 μmol g−1) were evaluated in experiments with pigs. In exp. 1, 1987 Tobin CM, VLG-CM and soybean meal (SBM) were compared in individually fed meal and pelleted diets. Daily gains from 23 to 57 kg were similar for the CMs (VLG-CM 662 g, Tobin CM 645 g) but lower than those obtained with SBM (730 g; P < 0.01). Daily feed intakes of pigs fed CM were lower than for those fed SBM (P < 0.05). Plasma thyroxine (T4) levels were similar for SBM and VLG-CM and were above those from pigs fed Tobin (P < 0.05) CM. Triiodothyronine (T3) levels were lower for VLG-CM than for SBM (P < 0.05) and the T3 value for Tobin CM was intermediate. Pelleting enhanced T3 (0.70 vs 0.94 ng mL−1) and T4 (50 vs. 60 ng mL−1) levels with all protein supplements (P < 0.01). In exp. 2, similar diets were fed ad libitum. Daily gains for SBM were greater than for Tobin CM (803 vs. 744, P < 0.05) and gains for pigs fed VLG-CM was 774 g. Daily feed intakes were similar (2.01, 1.99 and 1.92 kg). In exp. 3 energy digestibility of 1987 VLG-CM was greater (P < 0.01) than for Tobin CM (75.0 vs 67.4% for 30-kg pigs). Apparent digestibility coefficients of crude protein (CP) were 71.9, 71.2 and 71.6 in 16% CP diets. In exp. 4 Tobin and VLG-CMs from 1987 and 1988 crops were compared with SBM and commercial CM using 96 pigs (48M, 48F). Daily gains and feed intakes were similar for the CMs but T3 and T4 values were below those of SBM (P < 0.05). Key words: Canola meal, very low glucosinolate, digestibility, feeding value, pigs

Supplemental Protein

One hundred and eighty-six crossbred steers (194.4 ± 1.5 kg) were used to determine the effect of protein supplementation of medium-quality grass hay or silage on performance during wintering and compensatory growth during the grazing period. All steers received the hay or the silage ad libitum during the 182-d wintering period. They were also fed fixed quantities of one of three supplements: C, a control with no supplemental protein; CM, a canola meal; and FM, a fish meal containing supplements. Daily amounts of supplementation were fixed to supply to each steer the same amount of barley (85 g 100 kg−1 BW), of dry molasses (15 g 100 kg−1 BW) and of minerals, vitamins and Bovatec (10 g 100 kg−1 BW). The protein supplements CM and FM supplied the equivalent of 95 g of crude protein daily 100 kg−1 BW compared with 15 g 100 kg−1 BW for the control. Expressed as g kg−0.75, forage DM intake was 13.3% higher when fed as hay than as silage (P < 0.0001). Protein supplementation increased forage DM intake when fed as hay (P < 0.02) but not when fed as silage. Average daily gains (ADG) tended to be 5.8% higher for steers fed hay than for those fed silage (P = 0.06). Protein supplementation markedly improved ADG (P < 0.0001). When hay was fed, no differences were found in ADG between CM and FM supplementation; however, FM supplementation produced higher ADG than CM when silage was fed (P < 0.001). Feed efficiency was not affected by the type of forage fed, but it was higher for steers receiving protein supplementation (P < 0.001), the effect being more evident when the forage was fed as silage (P < 0.001) than when fed as hay (P = 0.07). Compensatory gains were obtained when the steers were taken out to pasture in early spring; steers fed silage, which obtained smaller ADG during wintering, showed higher ADG in pasture (P < 0.01). After 62 d grazing, the effect of protein supplementation during winter on body weight had almost disappeared. Key words: Protein supplementation, forages, cattle, growth

Sixteen large-frame crossbred beef steers (282 ± 5.5 kg) were used to determine the effect of canola meal (CM) supplementation on voluntary intake, average daily gains (ADG) and digestibility in growing cattle fed quackgrass (Agropyron repens) hay harvested at early heading. All animals received the hay ad libitum during the 81-d experiment. Seven steers received a supplement of 400 g (as fed) of CM per head daily. Average daily gains were 60% higher for steers receiving CM supplementation compared to those receiving only hay (0.93 vs. 0.58 kg, respectively, P < 0.001). Canola meal supplementation tended to improve hay intake by 8% (P = 0.06) when expressed in terms of g kg−0.75. Feed efficiency was 37.6% higher following CM supplementation (P < 0.001). Apparent DM and energy digestibilities were not different between diets, but protein digestibility was 2.9% higher for steers receiving CM (P < 0.01). On the other hand, apparent digestibilities of fibre components were lower in steers receiving CM (2.7% for neutral detergent fibre, P < 0.05, and 6.4% for acid detergent fibre, P < 0.001). Digestible energy of the total diets was only slightly higher for the one supplemented with CM (P = 0.10). The increase in ADG observed was partially explained by the increase in voluntary intake of the diet following CM supplementation. Key words: Canola meal, quackgrass hay, cattle, growth

Cent Level

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.

Two experiments of a factorial design (sex × treatment) were conducted to determine the effects of enzyme and salinomycin supplementation on the nutritive value of barley or rye-based diets for growing pigs fed from approximately 20 to 85 kg. For exp. 1, 72 crossbred pigs were fed either a barley-based control diet or a similar diet supplemented with enzyme (Aspergillus niger; 750 units g−1 beta-glucanase and 650 units g−1 pentosanase), salinomycin (25 ppm) or both additives in combination. For exp. 2, two replicates of 48 pigs were fed either a barley-based diet, an unsupplemented rye-based diet or a rye-based diet supplemented with enzyme, salinomycin or both additives. During both experiments, chromic oxide (0.5%) was added to the diet of four to six pigs/treatment to act as a digestibility indicator starting when the pigs reached 42 kg. Neither enzyme nor salinomycin, alone or in combination, significantly improved the growth rate or feed efficiency of pigs fed barley or rye. Supplementation of barley with the combination of additives significantly (P < 0.05) improved protein digestibility while neither enzyme nor salinomycin had any effect on nutrient digestibility when fed alone. In rye-based diets, salinomycin, both alone and in combination, significantly (P < 0.05) improved the digestibility of crude protein and energy. Dry matter digestibility of the rye-based diets was unaffected by treatment. Key words: Swine, rye, barley, beta-glucanase, pentosanase, salinomycin

Pomegranate by-products (peel and seed) contain about 40-45 percent of the fruit’s weight, but little information is available on their nutritive value. Chemical analysis of the pomegranate seed (PS) show that it contains average of 10-12 percent of crude protein. PS also contain a little amount of tannin (about 2.7 percent). Since feed accounts for 75-85% of the total costs of meet production and the use of them in feeding ruminant may decrease the cost of feeding. The objective of this experiment was also to determine nutrients digestibility of PS.

Knowledge on the nutritional value of feed ingredient is an important step in the formulation of diets in order to maximize animal productivity. Thus a study was conducted to determine the apparent digestibility coefficients (ADC) of dry matter (ADCDM), crude protein (ADCCP), gross energy (ADCGE) and amino acids (ADCAA) of conventional feed ingredients for juvenile silver mojarra (13.0 ± 3.23 g). The study was conducted in the laboratory for nutrition and feeding of fish (AQUANUT), using 80 silver mojarra collected in nature, which were kept in digestibility aquaria for a period of 21 days. The following ingredients were evaluated: fish meal, soybean meal, corn meal, corn gluten meal, rice bran, wheat bran and starch, which substituted 30% of a reference pelletized diet with 325.00 g kg-1 crude protein and 3,692 Kcal kg-1 gross energy. Additionally 1.0 g kg-1 chrome oxide was added to each diet as a marker. The excreta were obtained using three repetitions for each tested ingredient, which were dried for further analyses. The soybean meal showed the best ADCDM value (67.45%), followed by the other ingredients. There was no significant difference between the soybean meal (95.16%), fish meal (92.97%) and the corn meal (91.90%) for the best ADCCP coefficients. The ADCGE for soybean meal and maize meal were 65.23% and 60.31%, respectively, followed by fish meal (51.85%). The results demonstrate that silver mojarra can digest animal protein as well as that of vegetal origin. Silver mojarra can also efficiently digest and absorb some of the main amino acids of fish, such as lysine, methionine and threonine, from the same studied ingredients.

AbstractIn 22 cows given complete diets of 500 g straw and 500 g concentrates per kg fresh weight the outflow rate of small fibrous particles was determined on two occasions to investigate the consistency of this measurement and its association with apparent digestibility. The correlation between the outflow rates on the two occasions werer= +0·90 and the correlation with apparent digestibility wasr= −0·80.In a second experiment, the outflow rates of long and small particles were determined together with rumen retention time. There was no difference between outflow rate of long and small particles but rumen retention times were greater with the long particles. The correlation between the two estimates of outflow rate wasr= +0·84. The outflow rate of fish meal was found to be 0·070 while that of short fibrous particles was 0·031 per h. The average liquid outflow rate was 0·146 per h.The three cows with the highest outflow rate and the three with the lowest outflow rate from experiment 2 were selected for experiment 3. While voluntary food intakes of the two groups were similar, the differences in outflow rates between the cows persisted both withad libitumand restricted intakes of both a high and a low roughage diet. The differences were reflected in significant differences between the two groups in apparent digestibility of the diets. The practical implications for breeding and selection are discussed.

Two trials were carried out to examine the effects of crude protein level in rations for intensively-finished suckled bulls. In 1987/88 (Year 1) high levels were tested as a possible means of delaying finishing and in 1988/89 (Year 2) low levels were tested.In both years 54 Charolais x (Hereford x Friesian) bulls born in May-June were weaned in November, following paddock-grazing of cows and calves on permanent grassland. Following weaning, the bulls were housed in straw-bedded yards and offered wilted grass silage, with concentrate feed gradually increased. After 14 days the silage was removed and concentrates offered ad libitum. The bulls were allocated to 1 of 3 treatments with 2 replicates per treatment to provide 6 groups of 9 bulls. The experimental diets consisted of rolled barley with a pelleted protein concentrate and extra mineral supplement when appropriate, as described in Table 1. This resulted in diets with a range of protein but similar major mineral contents.
