AbstractTwo experiments were conducted to determine the nutritive value of extruded or raw peas (Pisum sativum as an energy and protein supplement for pigs of 33 to 100 kg live weight. Experiment 1 determined the effects of extrusion on the nutrient apparent digestibility of peas when included at 200 g and 400 g/kg in the diet. In experiment 2, performance was determined in individually fed pigs (no. = 70) offered diets ad libitum including a control (no peas, T1), 200 g/kg raw peas (T2), 400 g/kg raw peas (T3), 200 g/kg extruded peas (T4), 400g/kg extruded peas (T5). The peas were extruded at 120°С for 30 s. All diets were formulated to have similar concentrations of digestible energy (DE) and total lysine. There was a significant interaction effect (P < 0·05) between level of peas and extrusion on the digestibility of the organic matter (OM), nitrogen (N), energy and the DE content of the peas. The inclusion of 400 g/kg raw peas led to a lower estimated digestibility of OM (P < 0·001), N (P < 0·001), gross energy (P < 0·05) and DE content (P < 0·05) of the peas compared with the 200 g/kg peas. However, there was no difference (P > 0·05) between the digestibility of the 200 and 400 g/kg peas when the peas were extruded. In experiment 2, there was a significant interaction (P < 0·05) between the level of peas in the diet and extrusion. As the level of raw peas increased from 200 to 400g/kg, growth rate decreased (P < 0·01) and food conversion ratio (FCR) increased (P < 0·01). However, as the level of extruded peas was increased from 200 to 400g/ kg, there was no difference in either growth rate or FCR. It is concluded that extrusion of peas improved the nutrient digestibility and improved overall gain and FCR of the pigs.

AbstractTwo experiments were conducted to investigate the effect of expander processing of food for growing and finishing pigs. Experiment 1 examined the effects of expander processing on the nutritive value of a cereal-based diet and a pea-based diet for pigs while experiment 2 determined the effects of extrusion and expansion of the peas component of the diet on the nutritive value. In experiment 1, growth performance, carcass characteristics (no. = 12) and nutrient digestibility (no. = 4) were determined in pigs offered individually food containing a cereal diet (T1), a complete cereal diet that had been expander processed (T2), a 400 g/kg peas diet (T3) or a complete 400 g/kg peas diet that had been expander processed (T4). The expanded diets were processed at 105°C for 5 s at 35 bar pressure. In experiment 2, productive performance and nutrient digestibility were determined in pigs (no. = 12) offered individually diets including a control cereal diet (no peas) (TT1), a 400 g/kg raw peas diet (TT2), a 400 g/kg expander processed peas diet (TT3) or a 400 g/kg extruded peas diet (TT4). The pea portions of the diets were extruded at 130°C for 30 s and expanded at 130°C for 10 s at 42 bar pressure. In experiment 1, the inclusion of peas in the diet reduced (P < 0·001) the digestibility of the organic matter (OM) (0·871 v. 0·893, s.e. 0·003), protein (0·867 v. 0·907, s.e. 0·004) and energy (0·857 v. 0·880, s.e. 0·003). Expansion had no effect on the nutrient digestibility of the diets, however, it did increase (P < 0·05) the digestible energy content of the cereal diet. The inclusion of peas in the diet reduced (P < 0·05) daily gain (0·929 v. 0·999, s.e. 0·024 kg/day) and increased (P < 0·001) food conversion ratio (FCR) (2·31 v. 2·16, s.e. 0·029) from 34 kg to slaughter. Expansion had no effect on daily gain or FCR. In experiment 2, OM digestibilities of 0·891, 0·872, 0·882 and 0·885 (s.e. 0·0042) (P < 0·01), protein digestibilities of 0·905, 0·879, 0·874 and 0·877 (s.e. 0·0069) (P < 0·001) and gross energy digestibilities of 0·875, 0·861, 0·870 and 0·875 (s.e. 0·005) (P < 0·05) were recorded for TT1 to TT4 respectively. Gains (kg/day) of 0·981, 0·927, 0·940, and 1·016 (s.e. 0·036) (P < 0·05) and FCR of 2·17, 2·32, 2·28 and 2·18 (s.e. 0·037) (P < 0·05) were recorded for TT1 to TT4 respectively. In conclusion, expansion had no effect on the nutritive value of food for pigs.

AbstractTwo randomized-block experiments were carried out with growing pigs housed in groups of 10 from about 36 to 92 kg live weight and offered non-pelleted diets from single-space feeders containing separate food and water dispensers both operated by the pigs. The dispensing rate of food could be adjusted and rates of 1·4, 2·7 and 5·3 g per press of the nose plate were compared in experiment 1 and 4·8, 6·9 and 9·3 g per press compared in experiment 2. As dispensing rate increased in experiment 1 there were significant increases in food intake, growth rate and backfat thickness and a significant improvement in food conversion ratio on a carcass gain basis. There was no effect on the variation in growth rate between pigs within pens nor were there treatment effects in experiment 2 on any of the above measurements. The amount of food accumulating in troughs increased with feeder setting in both experiments.Behaviour at feeders was observed in each pen for 24 h during the 5th week using time-lapse video recording. The number of visits to feeders was not significantly affected in either experiment but time spent feeding was significantly increased at the lowest setting in experiment 1. Both the number of withdrawals from feeders accompanied by aggressive encounters and the number of pigs queuing decreased up to the dispensing rate of 6·9 g per press. There were tendencies for all parameters of behaviour to continue changing up to the highest dispensing rate.

Bull Calves

An experiment was conducted for a period of 60 days with twelve bull calves with an average live weight of 77.78 ± 10.96 kg to determine the effect of treatment of rice straw with Wood Ash Extract (WAE) on feed intake, nutritive value, growth rate and economic benefits. The experimental animals were divided into three groups A, B and C having four animals in each. They were supplied randomly with three rations following randomized complete block design. All rations were made iso-nitrogenous by using urea as a source of nitrogen. Animals of group A were fed untreated rice straw, whereas, group B and C were fed urea-treated and WAE treated rice straw, respectively. The chemical analysis showed that treatment of rice straw with WAE increased ash content of straw from 13.93% to 16.45% and decreased the NDF content from 67.39% to 63.00%. The daily DM intake per 100 kg live weight of diet B was significantly (P<0.01) higher than that of diet A and C. The daily CP intake per 100 kg body weight of diet B (553.3g) was significantly (P<0.05) higher than that of diet A (449.5g). Similarly, the organic matter (OM) intake in bull calves fed diet B was significantly (P<0.05) higher than those fed diet A and C. The average daily live weight gain with diet B and C was significantly (P<0.01) higher than diet A. The animals fed diet B and C were more efficient in converting feed into live weight than animals fed diet A. Treating rice straw with wood ash extract improved the nutritive value, it significantly (P<0.01) increased the apparent digestibility of DM, OM, CP, ADF and NDF. It also increased the DCP, DOM, DNDF and DADF contents of rice straw compared with untreated straw. Although the total feed cost of untreated group is lower than those of WAE and urea-treated groups, the feed cost per kg live weight gain as well as the feed cost per kg meat production of WAE and urea-treated groups were significantly (P<0.01) lower than that of untreated rice straw. It may be concluded that nutrient composition and digestibility of rice straw and live weight gain of animals can be improved by treating rice straw with wood ash extract.

Main Effects

AbstractA 2 ✕ 2 ✕ 3 factorial arrangement of treatments used 522 boars to examine the main effects and interactions of season (spring v. summer), number of pigs per pen with a single-space feeder (13 or 16 pigs per pen with a singlespace feeder; 0·78 m2 per pig v. 0·65 m2 floor space per pig) and nutrient density of the diet (12·5 g lysine per kg and 14·0 MJ digestible energy (DE) per kg from 38 kg to slaughter (high), 12·5 g lysine per kg and 14·0 MJ DE per kg during the growing phase and 10·0 g lysine per kg and 13·6 MJ DE per kg during the finishing phase (split) and 10 g lysine per kg and 13·6 MJ DE per kg from 38 kg to slaughter (low)) on the performance and carcass characteristics of growing and finishing pigs. The smaller group of pigs had a higher food intake during the grower-finisher period than the high stocked pigs (P < 0·01). The pigs had a higher lysine intake in the spring than in the summer months (P < 0·05). Differences in daily food intake for the smaller group of pigs were reflected in increased growth rate during the grower-finisher period (P < 0·001). However these pigs had a poorer food conversion ratio during the grower-finisher period (P < 0·05) than the bigger group of pigs. The pigs offered the high specification and split-fed diets had better growth rate (P < 0·05) than the pigs given the low specification diet during the grower and finisher period. There was a significant two-way interaction in growth rate between dietary treatment and season during the finisher period (P < 0·01). The pigs given the high specification diet had a better growth rate (P < 0·001) than the pigs given the low diets during the summer months. However, the high specification diet depressed growth rate during the spring months (P < 0·05). The pigs had a lower backfat and higher lean meat in the summer than in the spring months (P < 0·05).

Experimental Treatments

ABSTRACTGrowing pigs were given diets based on barley (whole or milled), which was either untreated or sprayed with an aqueous solution of sodium hydroxide (270 g sodium hydroxide per kg water) to give 33·8 g sodium hydroxide per kg dry matter. The barley grain was treated with sodium hydroxide while in the whole state. A total of 48 pigs penned individually were given the diets on a restricted scale of feeding from an initial weight of 31·6 kg until slaughter at 81·7 kg live weight. In a metabolism study, eight boars were subjected to the same experimental treatments in two identical 4 × 4 balanced change-over experiments.The diet containing untreated milled barley gave significantly faster live-weight gain and lower food conversion ratio than the other three diets (P < 0·001). Food conversion ratios were similar for untreated whole barley and sodium hydroxide-treated barley, whether this was whole or milled. Killingout proportion was similar for untreated and treated milled barley but was significantly lower when the diet contained untreated or treated whole barley.Milling significantly increased the digestibility of energy and nitrogen. Treatment with sodium hydroxide improved the digestibility of energy in the diet with whole barley but not in the diet with milled barley. With both whole and milled barley, treatment with sodium hydroxide increased the digestibility of crude fibre (P < 0·05) but with ground barley the digestibility and retention of nitrogen were reduced considerably by treatment with sodium hydroxide.It is concluded that treatment of barley with sodium hydroxide did not improve the nutritive value of either milled or whole grain, that it reduced the digestibility of nitrogen and that it severely depressed the utilization of digested energy for growth.

AbstractTwo experiments were completed with grower-finisher pigs to determine if pigmeat output, as measured by carcass gain per m2 per year, could be increased, by 1: increasing group size or 2: split-marketing pen groups. In experiment 1, 390 pigs (mean initial live weight 36·7 (s.d. 1·99) kg) were assigned to one of three treatments each with 10 replicates: 11, 13 or 15 pigs per single-sex group in pens measuring 11·04 m2. Space allowance was 1·00, 0·85 and 0·74 m2 per pig, respectively. Pelleted food was provided ad libitum. There were no differences (P > 0·05) between group sizes in growth rate, food intake, food conversion ratio, carcass growth and carcass food conversion ratio, backfat and muscle depth or carcass lean content. Pigmeat output per unit area increased with each increase in group size (234, 279 and 314 kg/m2 per year for 11, 13 and 15 pigs: P < 0·001). In experiment 2, 26 groups of 13 pigs (mean initial live weight 38·3 (s.d. 2·15) kg) were assigned to one of three treatments: 1D - group sold on 1 day (no. = 9), 2D - group sold over 2 days (14 days apart, no. = 10), or 3D - group sold over 3 days (each 7 days apart, no. = 7). Pigs were given a standard liquid diet three times daily. No differences (P > 0·05) were observed between treatments for overall growth rate, food intake, food conversion ratio, carcass weight, carcass lean content, backfat and muscle depth, carcass growth and carcass food conversion ratio or killing-out proportion of pigs. Split-marketing increased cycle length (67·7, 75·9 and 76·8 days for 1D, 2D and 3D, respectively; P < 0·001). Live and carcass daily growth rates per pig place decreased with increase in number of sale days (live: 772, 680, 670 g/day and carcass: 658, 575, 571 g/day; P < 0·001). Carcass gain per unit area decreased in split-marketed groups (358, 318, 312 kg/m2 per year for 1D, 2D and 3D, respectively: P < 0·05). Carcass weight variation (s.d.) within pen decreased with each increase in number of sale days (s. d. 5·28, 3·81 and 1·74, respectively; P < 0·001). In conclusion, pigmeat output, as measured by carcass gains per m2 per year, was improved with increase in group size and by marketing all pigs in a group on a single day.

Fish Protein Hydrolysates

SUMMARYMale and female (Suffolk × (Finnish Landraee × Dorset Horn)) lambs were used in three experiments to examine the replacement of milk by undried and dried fish protein hydrolysates (FPH), a mixture of lard and coconut fat, and partially hydrolysed starch (Protamyl 110). The animals received the experimental diets from 1 week of age in Expts 1 and 2, and from 4 weeks of age in Expt 3. They were given the diets in eight equal feeds (i.e. every 3 h) from an automated teat bar system. The level of feeding was 1·046 MJ/kg0−76/day. Experiments 1 and 2 lasted for 35 days, during which live-weight gain and food conversion ratios were recorded and at the end the digestibility of N, dry matter and starch was determined. Experiment 3 consisted of three small digestibility trials.In Expt 1, the replacement of milk protein with undried FPH and of milk fat with lard plus coconut fat had no significant effects on live-weight gain, food conversion ratio or nutrient digestibility. Somewhat lower gains for the lambs given the FPH than those given milk protein were observed during the first 15 days of the experiment. Apparent digestibility of milk protein and milk fat was 95 and 99% while that of PFH and lard plus coconut fat was 94 and 96% respectively. The replacement of milk fat with lard and coconut fat caused some reduction in live-weight gains and nutrient digestibility. Lactose was completely replaced by protamyl both in diets based on milk protein or FPH with no effect on live-weight gains or food conversion ratio.Apparent digestibility of fish protein was not affected by the drying process. Fat digestibility of diets containing undried or dried FPH ranged from 46 to 98% according to the type of emulsifier used. The results are discussed in relation to published data concerning the problems associated with the use of fish protein in milk replacers.

ABSTRACT1. Three isocaloric diets containing 170, 210 or 231 g crude protein per kg were given at two levels, and offered ad libitum to entire and castrated male pigs growing from 20 to 70 kg live weight.2. Between 20 and 45 kg, growth rate improved with each increase in level of feeding (P < 005) and, on the ad libitum treatment the food intake and growth performance of both entire and castrated pigs were similar. On the restricted feeding treatments the growth performance of entire, but not of castrated pigs, improved when dietary protein was raised from 170 to 210g/kg (P < 005).3. During the live-weight periods 45 to 70 and 20 to 70kg, raising food intake improved growth rate (P < 005) but increased the food conversion ratio and carcass fat measurements at 70 kg (P < 0·05). However, food conversion ratio and the majority of carcass characteristics of entire pigs fed ad libitum were equivalent to those of castrated pigs fed at the lowest level.4. Dietary protein level had no significant effect on growth performance from 20 to 70 kg or on carcass fat measurements at the latter weight. However, each increase in dietary protein in the live-weight period 45 to 70 kg depressed the performance of castrated pigs (P < 0·05) while that of entire pigs was reduced when the protein level of the diet was raised from 210 to 231 g/kg.

The use of full-fat rapeseed in non-ruminant animal feeding has for long been limited by the presence of anti-nutritive components. However, triple-low varieties have a considerable potential as a source of both protein and dietary energy in diets, although there is the need for precise information on the relative nutritive value of full-fat rapeseed and the resulting extracted oils and meals before they may be effectively and economically incorporated into animal diets.The rapeseed products evaluated comprised ground full-fat rapeseed (FFRS) extracted rapeseed meal (RSM) and rapeseed oil (RSO) all from a triple-low variety, Brassica campestris SVO 333, obtained from Dalgety-Panmure Co. Angus, U.K. The RSO, RSO plus RSM (ORSM) and FFRS were included to give levels of added oil of 40, 80 and 120 g/kg at the expense of the energy-yielding ingredients of the basal diet (Table 1). The RSM was incorporated into the basal at the same rates as in ORSM. All experimental diets were fed to 13 Landrace x (Landrace x Large White) gilts of 46kg average initial live weight in a metabolism trial conducted over four successive time periods. A ten-day acclimatisation in holding pens preceded a 5-day total collection of faeces (using indigo carmine as marker) and urine (facilitated by indwelling bladder catheter) in metabolism crates. The rapeseed products, diets, oven-dried faeces and freeze-dried urine were analysed for gross energy (GE) and (except urine) for oil content. Apparent digestible energy (DE) of test materials were derived by regression analysis. DE of oil was also derived indirectly as a product of oil digestibility and oil GE.

SUMMARY1. In three experiments, 112 7-day-old British Friesian male calves were used in performance and digestibility trials to evaluate dried cooked potato in liquid and creep diets.2. A 15% depression in growth rate for each 10% inclusion of cooked potato flour in liquid diets was recorded from 4 to 21 days and the faeces of potato-fed calves also tended to be less solid. Over the whole feeding period, liquid diets containing up to 20% potato did not significantly depress performance to weaning at 35 days.3. Only when a liquid diet containing potato starch was introduced prior to 4 weeks of age was daily live-weight gain markedly depressed.4. Incorporating potato starch in milk diets did not influence creep intake.5. Calves offered a creep diet containing 40% cooked potato flake ate less, but grew faster than calves given a diet containing 40% flakedmaize. At constant intakes of creep, daily gains were 14 to 18% greater on the diet containing potato flake.6. The apparent digestibility of gross energy and nitrogen was 0·67 and 0·66 for the flaked maize creep and 0·71 and 0·69 for the potato creep. Digestible energy and digestible nitrogen values were 12·7 MJ and 18·2 g/kg dry matter for the maize diet and 13·0 MJ and 19·0 g/kg dry matter for the flaked potato diet.7. The incidence of bloat was higher for calves fed on potato than for those fed on maize.
