Distillers Grain

The physiochemical properties and digestible, metabolizable, and predicted net energy contents in high-protein dried distillers’ grain (HiPro) were determined to assess the nutritive value for growing pigs. Twelve Yorkshire × Landrace barrows (initial body weight 25 ± 0.5 kg) were used in a partially replicated Latin square design over three periods (n = 7 or 8) and assigned to one of five experimental diets. In each period, pigs were adapted to diets for 7 d, followed by 5 d of total urine collection and fecal grab sampling. The experimental diets included a corn- and soybean-meal-based diet (CON) or diets containing dried distillers’ grains with solubles (DDGS) or HiPro to partially replace corn and soybean meal, without or with (i.e., DDGS+ and Hipro+) a multi-carbohydrase enzyme blend (0.05% inclusion). The HiPro ingredient contained half as much starch (2.6% vs. 5.2%; DM-basis), 20% more protein (32.5% vs. 27.1%), and had 14% greater water binding capacity versus DDGS. The digestible, metabolizable, and predicted net energy contents of the HiPro co-product were greater than DDGS for growing pigs (P < 0.05), but fibre-degrading enzymes were ineffective at improving energy values. The greater (available) energy and protein contents of HiPro make it a promising feed ingredient for inclusion in swine diets.

Protein Supplements

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.

Laboratory-prepared rapeseed meals (RSMs) with moisture contents ranging from 2 to 40% of the meal were heated in an autoclave or an oven at 121 °C from 15 min to 4 h. The degree of protein denaturation of the RSMs was estimated by nitrogen solubility (NS) in water and by dye-binding capacity of the protein (DBCP) with Acid Orange 12. The NS study indicated that heating RSM for 15 min to 1 h in an autoclave produced more severe denaturation than heating RSM at a similar temperature for the same periods of time in an oven. When heating in the autoclave was prolonged, the nitrogen solubility increased. The ability of the RSM protein to bind Acid Orange 12 was more severely affected by the autoclave treatment than by oven heating. In this regard, the DBCP of the RSMs was at the lowest after 2 h of heating in the autoclave and after 4 h of heating in the oven. Since the NS values for the RSMs include both protein and non-protein nitrogen while DBCP values measure mainly basic amino acids, the latter values are likely to be more valid for estimating the nutritive value of RSM. The higher correlation coefficient between DBCP and available lysine than between NS and available lysine (0.90 vs. 0.63) would seem to support this conclusion.

SummaryThe nitrogen solubility index (NSI) method for the examination of caseinates was evaluated. It was found that widely scattering NSI values are mainly due to ineffective centrifugation and filtration of the caseinate dispersion. In order to avoid this, an improved combined centrifugation–filtration procedure was developed as an alternative to the original NSI method, using an Amicon micropartition system MPS-1 equipped with discs of filter paper. The micropartition devices can be centrifuged in a Gerber centrifuge of the type used for butyromctric fat determination. Several types of caseinates were evaluated with the new method and yielded a markedly smaller range of single values than were obtained with the NSI method.

Weaner Pigs

Two experiments were conducted to examine the nutritive value of yellow lupins for weaner pigs. Using a completely randomised block design, Experiment 1 was conducted to determine the optimum inclusion level for yellow lupins (cv. Wodjil) in the diet of weaner pigs (6.14 kg ± 0.278). Experiment 2 was conducted using a 2 × 2 factorial design to examine whether supplementation of an enzyme preparation (VegPro) either in a soybean meal-based diet (0 g/kg yellow lupins) or in a yellow lupin-based diet (150 g/kg) improved performance of piglets (6.17 kg ± 0.317). In Experiment 1, the feed conversion ratio significantly increased at week 1 (linear effect, P = 0.040) and at week 3 (quadratic effect, P = 0.010) as the concentration of yellow lupins increased in the diet. In Experiment 2, supplementation with the enzyme preparation improved the feed conversion ratio in the pigs fed the lupin-based diet only but not in the pigs fed the soybean meal-based diet in week 2 (interaction P = 0.001). The results indicate that the optimum inclusion levels of yellow lupins for piglets immediately after weaning was 150 g/kg, and supplementation of a multi-enzyme preparation to a yellow lupin-based diet for the weaner pigs improved performance relative to the soybean meal-based diet.

In two experiments pigs were individually and restrictively fed from approximately 24 to 83 kg liveweight. The diets consisted of wheats of varying protein content supplemented with four levels of soybean meal. In experiment 1, wheats of 19.2 per cent and 11.5 per cent crude protein were compared and in experiment 2, the per cent crude protein content of the wheats was 14.9 and 13.1. Average daily gains, feed conversion ratios and carcase characteristics were not significantly affected by source of wheat in experiment 1, whereas in experiment 2, the 14.9 per cent protein wheat resulted in average daily gains and feed conversion ratios significantly superior to the 13.1 per cent protein wheat. Average daily gains and feed conversion ratios in both experiments and carcase quality in experiment 2 improved with increasing level of soybean meal supplementation. The interaction of wheat source x soybean meal level was significant only for backfat thickness in experiment 2. The level of soybean meal at which backfat thickness significantly increased was 6 per cent and 3 per cent with wheats of 14.9 per cent and 13.1 per cent protein respectively. The observed growth performance and carcase quality between the wheats fed appeared to be unrelated to the determined essential amino acid content of the wheat.
