AbstractA total of 276 crossbred pigs were used in three trials to determine if feeding spray-dried animal plasma (SDAP) in simple phase 1 piglet diets with differing soya-bean meal (SBM) levels can influence performance or immunoglobulin G (IgG) levels specific to the antigenic soya proteins, glycinin and β-conglycinin. Pigs were blocked according to initial body weight and equalized across treatments according to gender and ancestry. Blocks of pigs were then randomly assigned to one of three treatments in a completely randomized block design. The dietary treatments were as follows: (1) 10% +: 100 g/kg SBM with 75 g/kg SDAP; (2) 20% +: 200 g/kg SBM with 75 g/ kg SDAP; (3) 20%-: 200 g/kg SBM without SDAP. Pigs were given treatment diets for 14 days, followed by a common diet for the duration of the trials (35 days). Average daily gain (ADG) and gain to food (G: F) ratios were not affected by dietary treatments. Average daily food intake (ADFI), however, was greater for pigs given 10% + as compared with 20% + and 20%- (P < 0.05) during days 0 to 14 post weaning. Addition of SDAP increased ADFI (P < 0.01) and tended to increase ADFI when added to diets containing 200 g/kg of soya-bean meal (P = 0.06). No differences were detected in soya-specific IgG levels during any collection period. These data suggest that SDAP addition to simple phase 1 piglet diets increased ADFI during the first 2 weeks, but did not alter ADG or food efficiency. There was no indication that SDAP addition altered IgG titres against the soya-bean proteins, glycinin and β-conglycinin.

Soya Bean Meal

Rapeseed, sunflower and soya-bean meals were compared as the main sources of protein in concentrate supplements given to dairy cattle. The supplements contained (per kg) 620 g rapeseed meal, 760 g sunflower meal or 500 g soya-bean meal and all three were formulated to contain 300 g protein per kg. Each animal was given daily TO kg dairy compound, 3·5 kg supplement, 3·5 kg sugar-beet pulp pellets and offered maize silage ad libitum. A randomized-block design with 39 cattle was used and treatments were applied for 16 weeks. All three supplements were eaten rapidly and there were no refusals. Daily mean milk yields were rapeseed 26·7, sunflower 25·3 and soya bean 25·1 (s.e.d. 1·44) kg; milk fat and protein concentrations were not affected by the treatments. There were no significant treatment differences in live weight and condition score. It was concluded that these high protein supplements based on rapeseed meal, sunflower meal and soya-bean meal were of equal feeding value for milk production.

Synthetic lysine and fat supplements are widely used in diets for growing pigs. However, there is evidence to suggest that free lysine is more rapidly absorbed than protein bound amino acids resulting in reduced growth performance particularly under infrequent feeding regimes. In addition, the incorporation of conventional fat supplements into cereal based diets is problematic particularly where on-farm mixing of feed is carried out. One potential solution to both these problems is to use fat coated synthetic lysine sources which have recently become available and two such materials were evaluated in this study.Four dietary treatments were compared. These were a control diet (C) with soya bean meal as the protein supplement and diets in which 0.3 of the total lysine was supplied from either synthetic lysine (S) or synthetic lysine coated with a single (SC) or a double layer(DC) of hardened soya oil. All diets were barley based and were formulated to contain the same level of total lysine (0.01) and hardened soya oil.

1. The biological evaluation of solvent and prepress-solvent processed rapeseed meals RM(S) and RM(PS) was carried out with the weanling (phase 1) and the mature (phase 2) rat. The nutritional indices measured were compared with those for diets containing soyabean meal SM and casein CS.2. The true nitrogen digestibility (td(N)) for RM(S), RM(PS), SM and CS in the weanling rat was (%) 78.9 f±1.2, 77.9±2.7, 90.4±0.9 and 96.0±0.6 (P < 0.01) respectively. Net protein utilization was (%) 68.9±10.1, 65.6±3.5, 80.6±4.8 and 81.7±3.1 (P < 0.05) respectively. Biological value was (%) 83.0±7.9, 84.1±5.6, 8.90±5.1 and 85.0±3.4 (P < 0.05) respectively. The same indices when measured in the mature rat showed an increase over those obtained in the weanling rat.3. The growth-promoting effects of the test diets were evaluated over a period of 8 weeks with ad lib. feeding between phases 1 and 2. Protein efficiency ratio averaged 2.0±0.14, 1.9±0.35, 2.4±0.39 and 2.3±0.25 for the RM(S), RM(PS), SM and CS treatments respectively.4. The daily endogenous urinary N excretion was 1.58±0.14 mg N/basal kcal or 254 mg N/kg body-weight for the weanling rat and 0.16 mg N/basal kcal or 18 mg N/kg body-weight for the mature rat. Metabolic faecal N excretion was 98.0±9.3 mg N/kg body-weight, or 27.9% of the total N output for the weanling rat, and 37.9±7.2 mg N/kg body-weight, or 67.3% of the total N output for the mature rat during the ‘protein-free’ feeding periods.5. The fresh weight of the thyroid gland per kg metabolic body size was 70, 90, 40 and 40 mg respectively for the RM(S), RM(PS), SM and CS dietary treatments.6. The moisture content of the carcasses was 66.9±3.1, 63.6±2.3 and 64.2±2.2 and the protein content on a dry-matter basis was 55.9±9.6, 50.2±6.4 and 53.1±4.9 for the RM (S and PS), SM and CS diets respectively. The results suggest an increased lean body mass in the rats receiving the rapeseed meal treatments.7. Under the conditions of this experiment solvent-extracted rapeseed meal was superior to prepress-solvent meal on the basis of rat growth response and of results for nutritional indices. Both rapeseed meals were inferior to soya-bean meal and casein.

AbstractA 3 ✕ 2 factorial experiment was conducted to investigate the interaction between lactofeed 70 (LF70) (860 g/kg whey permeate, 140 g/kg soya-bean meal, Volac International, UK) levels and soya-bean meal inclusion (SBM) (90 and 225 g/kg) from day 0 to day 25 after weaning (starter period) on growth performance and diet digestibility. A common diet was offered from day 25 to day 38. Dietary treatments were established by substituting LF70 for extruded wheat and soya-bean meal for potato protein (PP) and soya protein concentrate (SPC). Digestible energy and amino acids were maintained by adjusting soya oil and synthetic amino acids. A total of 252 pigs (7·7 kg and 28 ± 2 days of age) were allotted randomly to six treatments containing (1) 0 LF70 with 40 g/kg PP and 40 g/kg SPC and 90 g/kg SBM (2) 0 LF70 with 225 g/kg SBM (3) 175 g/kg LF70 with 40 g/kg PP and 40 g/kg SPC and 90 g/kg SBM (4) 175 g/kg LF70 with 225 g/kg SBM (5) 350 g/kg LF70 with 40 g/kg PP, 40 g/kg SPC and 90 g/kg SBM and (6) 350 g/kg LF70 with 225 g/kg SBM. There was an increase in average daily gain (ADG) (0·182 v. 0·292 v. 0·318 kg, s.e. 0·0089; P < 0·001) and food intake (0·413 v. 0·472 v. 0·489 kg, s.e. 0·0139; P < 0·01) and an improvement in food conversion ratio (FCR) (2·31 v. 1·63 v. 1·55 kg, s.e. 0·037; P < 0·001) as the level of LF70 increased during the starter period. From day 25 to day 38, the pigs given the starter diets containing no LF70 had an improved ADG (P < 0·05) and FCR (P < 0·001) compared with the pigs given 175 and 350 g/kg LF70. The pigs offered diets containing 350 g/kg lactofeed had a significantly higher N digestibility (P < 0·05) than the pigs offered diets containing no lactofeed. There was a significant interaction (P < 0·001) between LF70 and SBM in the apparent digestibility of gross energy (GED). Pigs given higher SBM diets had a higher GED at the 350 g/kg LF70 inclusion than pigs given PP + SPC diets. However, there was no difference in GED at the 0 and 175 g/kg LF70 inclusion. In conclusion, the inclusion of LF70 increased ADG, food intake and apparent N digestibility and improved FCR.

Growth parameters (standard length, weight, specific growth rate and daily weight gain) of prawn Macrobrachium tenellum juveniles fed 40% crude protein isoproteic diets substituting fish meal with soya bean meal at various levels (20, 40, 60, 80 and 100%) were evaluated for 45 days under laboratory conditions. Experimental diets were compared with a 100% fish meal based diet. Total survival was recorded for all the treatments at the end of the experiment. There were no significant differences (p > 0.05) for all the growth parameters among the dietary treatments. The initial mean weight (0.36 ± 0.10 g) increased almost three times (1.00 ± 0.13 g) after 45 days. The final specific growth fluctuated from 1.82% BW/d for the 60% soya bean meal inclusion diet, to 2.62% for the 100% fish meal diet. The mean final survival was 91.66%. Growth performance of M. tenellum juveniles was not affected by the dietary soya bean meal levels tested.

AbstractDuring two experimental periods, eight non-lactating, rumen fistulated Simmental cows were given 2 kg/day of a cereal based concentrate and fescue hay ad libitum. The hay differed in neutral-detergent fibre concentration (LNDF: low; HNDF: high) and physical form (L: long; C: coarsely chopped). The rumen degradability of the dietary ingredients and of an extracted soya-bean meal was studied using the polyester-bag method.The estimated effective rumen degradability <DG) of dry matter (DM) was significantly higher for LNDF than for HNDF hay (0·490 v. 0·401; P < 0·01). The DM DG of the extracted soya-bean meal and the dietary concentrate were higher when incubated with LNDF than with HNDF diets (0·630 v. 0·581, P < 0·05, and 0·541 v. 0·514, respectively).Chopping the hay significantly increased the daily DM intake for HNDF diets (from 9·9 to 11·6 kg; P < 0·05), while no statistical differences were found between the other diets (10·2 and 9·6 kg, respectively for L-LNDF and C-LNDF diets). Cows given HNDF hay drank less water (42·4 v. 51·7 I/day) and total water consumption, expressed per unit of DM intake, was lower for the HNDF diets (4·1 v. 5·3 I/kg DM; P < 0·01).Dietary treatments did not affect the estimated rumen turn-over rate of hay (0·027 per h on average, k1), hay post-rumen turn-over rate (0·069 per h on average, k2) or the estimated rumen liquid turn-over rate (0·100 per h on average, kj. The calculated outflow from the rumen was lower for the HNDF diets (159·4 v. 198·7 I/day). The daily amount of estimated saliva secreted did not differ between treatments, although saliva expressed per kg DM intake was significantly lower for the HNDF diets (10·8 v. 14·8 I/kg DM; P < 0·05).The HNDF diets gave a lower post-feeding rumen pH (6·29 v. 6·58; P < 0·01), a higher concentration of n-butyrate (9·58 v. 8·32 mmol/l; P < 0·05) and a lower concentration of ammonia nitrogen (NH3-N) (80·5 v. 128·5 mg/l; P < 0·05). Of the C4 and C5 iso-acids, the rumen liquid from cows given HNDF diets had significantly lower concentrations of isobutyrate, isovalerate and n-valerate (P < 0·01). Hay physical form did not affect rumen pH, NH3-N and volatile fatty acid concentrations.

ABSTRACTThree experiments, designed as three simultaneous 4 × 4 Latin squares (21-day feeding periods), were conducted using pregnant beef cows. Diets were based on barley straw given ad libitum together with 1·7 kg dry matter (DM) of either molassed sugar-beet pulp (MSBP) (experiment 1), unmolassed sugarbeet pulp (USBP) (experiment 2), or rolled barley (BARLEY) (experiment 3). In the respective experiments, MSBP, USBP and BARLEY were given either alone, to provide about 200 g crude protein (CP) per day (CONTROL) or were supplemented with urea (U), untreated soya-bean meal (SBM) or formaldehyde-treated soya-bean meal (FT-SBM) to provide a further 200 g CP per day. The contrasting dietary treatments in the three experiments provided intakes of rumen-degradable protein (RDP) ranging from 16 to 388 g/day.All protein supplements improved overall straw DM intakes, the improvement being significant for U only (P < 0·01). A linear relationship between the daily intake of RDP (g) and straw DM (kg) was obtained. The regression equation was:DM intake = 5·03 + 0·0035 × RDP (R2 = 0·703; residual s.d. 0·561; d.f. 35; P < 0·001).All protein supplements also improved the apparent digestibility of straw organic matter (OM) (P < 0·05) and the metabolizable energy (ME) obtained from straw (P < 0·01). Blood urea was increased due to supplementation with urea (P < 0·001), SBM (P < 0·01) and FT-SBM (P < 0·05). Supplementation with BARLEY appeared to improve straw DM intake over MSBP and USBP but this was not reflected in improved ME intake from straw.

SUMMARY1. Pelleted grass and a concentrate containing 90% rolled barley and 10% soya bean meal were offered to cows in three combinations, 25: 75, 50: 50 and 75: 25 respectively, together with a constant low level of coarse roughage.2. The experiment was carried out in two stages, in early lactation as a randomized block design involving 18 Jersey cows fed to appetite and in mid-lactation as a 3 × 3 Latin square change-over design involving 12 cows, rationed according to milk yield.3. There were no significant between-treatment differences in either milk yield or milk fat content in either stage of the experiment.

AbstractAn experiment was carried out to study the effect of addingα-galactosidase to the diet on the performance and digestive parameters of growing-finishing pigs. Fifty-four gilts, average body weight (BW) of 43 (s.e. 0·4) kg, were allocated to 18 pens and used in a production experiment divided in two consecutive periods of 28 days each (growing and finishing). In each period gilts were given a diet based on cereals, soya-bean meal and peas, supplemented (Enzyme) or unsupplemented (Control) with 200 units per kg ofα-galactosidase. All diets included 2 g Cr2O3per kg as a digestibility marker. Food intake and body weight were recorded every 2 weeks and faecal samples by pen were collected at the end of each period. Average daily gain (ADG), food: gain ratio and faecal digestibility of dry matter (DM), crude protein (CP) and neutral-detergent fibre (NDF) were calculated. At the end of the production experiment nine gilts from each treatment were selected and given the finishing diet for a further 10 days before being slaughtered. Samples of digesta from the ileum and caecum were collected and ileal digestibility of monosaccharides determined. Short chain volatile fatty acids (SCVFA ) and purine bases (PB) in caecal digesta were analysed. The use ofα-galactosidase improved the ADG (P< 0·01) and the food: gain ratio (P< 0·01) simultaneous to increases in the faecal digestibility of DM (P< 0·05), CP (P< 0·05) and NDF (P= 0·07) in the finishing period. Alpha-galactosidase supplementation also improved the ileal digestibility of some monosaccharides (galactose, rhamnose, mannose and fucose) of the dietary fibre fraction (P< 0·05); and reduced total caecal concentration of SCVFA (P= 0·15), proportion of branched-chain VFA (P< 0·001), and concentration of total PB (P< 0·001). It is concluded that addingα-galactosidase to a cereal-soya-bean meal-pea diet improves ADG, food: gain ratio and digestibility in fattening pigs, and reduces the amount of fermentable substrate flowing to the large intestine.

Two feeding experiments with housed lambs of the Spanish Manchega breed were carried out over 2 years with the aim of assessing the suitability of field beans in lamb finishing diets. In the 1st year field beans were compared with soya-bean meal as a protein source in a factorial experimental design with the proportion of maize in the diet being 0·15, 0·25 or 0·35. In the second experiment the effect of replacing soya-bean meal and sunflower meal by inclusion of field beans at proportions, 0, 0·1, 0·2, 0·3 and 04 of the diet was studied. All diets were isoenergetic and isoproteic. The composition of the diets had no significant effects on the average daily gain or the food conversion ratio in either experiment. Results from experiment 2 showed that the increasing amount of field beans in the basal diet did not affect protein, fat and water content of a loin sample of meat, or fatty acid composition of kidney fat.
