Mustard seed batches of Brassica hirta 'Sabre' and of B. juncea 'Oriental' were oil-extracted, treated with Na2CO3 solutions to provide 0, 1 and 2% Na2CO3 based on meal, heat-treated, fed to growing pigs in diets containing 16–17% protein and tested in digestibility trials. Heat treatment alone resulted in significant reductions in glucosinolate content, especially of the allyl type in B. juncea. Na2CO3 treatment reduced glucosinolate and sinapine contents by 20–40% and reduced available lysine by 15–20%. Growth responses of swine showed Oriental meal to be inferior to Sabre meal and both inferior to soybean meal. Digestibility of Sabre protein was 64%; digestibility of energy was 65%, giving 12.3 MJ digestible energy (DE) per kilogram. Digestibility of Oriental protein was 87%; digestibility of energy was 65%, giving 12.3 MJ DE/kg. The nutritional differences between the mustard meals and soybean meal were attributed to glucosinolates affecting palatability or thyroid function, since available energy, protein or lysine were not sufficiently limiting in the diets to account for the dietary responses obtained. Nitrogen-to-protein conversion factors, correcting for both the amino acid composition of the protein and for the non-protein nitrogen component, were about 4.43 and 4.95 for mustard meals and soybean meal respectively.

Four experiments were conducted with rats to investigate the effects of autoclaving and alkali treatment on the growth-promoting ability of pigeonpea meal. In the fifth experiment, the effect of autoclaving pigeonpea meal was evaluated with pigs. With rats, there was a quadratic response (P < 0.05) in growth and feed conversion ratio to autoclaving pigeonpea seed for 15 min at 100-140�C, with maximum response occurring at c. 124�C. However, growth rate was still lower and feed conversion ratio higher than those of rats fed soybean meal (P < 0.05). Imbibing pigeonpea seed in alkali and subsequently drying it to original weight did not reduce tannin content but did reduce the trypsin-inhibitor activity from 10.3 to 5.1 units mg-1. Although both alkali treatment and autoclaving of the alkali-treated seed improved the growth and feed conversion ratios of rats, these treatments did not overcome the differences in protein quality between the pigeonpea and soybean meal diets. Autoclaving pigeonpea seed for 15 min at 110, 124 and 140�C reduced the trypsin-inhibitor activity of the meals from 11.2 to 0.7 units mg-'. Compared to pigs fed on unheated pigeonpea meal, pigs given autoclaved meal had higher (P < 0.05) growth rates and improved feed conversion ratios. These improved growth responses were similar to those produced by soybean meal.

Abstract The objective was to determine the influence of amino acid (AA) supplementation during the adaptation period on the ileal digestibility of crude protein and AA in corn and soybean meal (SBM). Six barrows with an initial body weight of 30.9 ± 2.6 kg fitted with a T-cannula in the distal ileum were assigned to a 6 × 6 Latin square design with 6 dietary treatments and 6 periods. Two experimental diets contained corn or SBM as the sole source of AA and an N-free diet was additionally prepared. For AA supplementation groups, an AA mixture consisted of Gly, Lys, Met, Thr, Trp, Ile, Val, His, and Phe was added to the corn diet and the N-free diet at the expense of cornstarch, and an AA mixture of Lys, Met, and Thr was added to the SBM diet. All diets contained 0.5% of chromic oxide. The 6 experimental diets were fed to the pigs for 4 and half days, and the 3 diets containing AA mixture were switched to the respective diets without AA mixture during the following 2 and half days. Ileal digesta were collected during the last 2 days. The addition of AA mixture during the adaptation period caused increased apparent ileal digestibility of Arg and Trp in corn (P &lt; 0.05), but did not affect that in SBM. The addition of AA mixture during the adaptation period caused increased apparent ileal digestibility of Pro and Gly regardless of feed ingredient (P &lt; 0.05), but did not affect that of other AA. All AA except Pro in corn and SBM were unaffected by the addition of AA mixture during the adaptation period. In conclusion, the addition of amino acid during the adaptation period does not affect the standardized ileal digestibility of indispensable amino acids in feed ingredients.

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.

Arginine Concentration

1. The catabolism of L-[ l-14C]phenylalanine was used to indicate the effects of single amino acid supplementation of an inadequate protein diet (200 g crude protein (nitrogen x 6.25)/kg) on the utilization of dietary amino acids in pigs of 2.5 kg body-weight reared on an adequate protein diet (240 g crude protein/kg) containing skim milk and a mixture of free amino acids.2. The oxidation of phenylalanine was decreased by the addition of proline or arginine to the inadequate protein diet but not by the addition of threonine, methionine, lysine or a mixture of essential amino acids, indicating that proline and arginine were limiting the utilization of dietary amino acids in the inadequate protein diet.3. Dietary proline concentrations of 13.9 and 14.2 g/kg minimized phenylalanine oxidation in diets containing 200 or 260 g protein/kg. This indicates a dietary proline requirement of 14 g/kg.4. Increasing the dietary arginine concentration in a diet containing 240 g protein/kg showed that an arginine concentration of 5.1 g/kg minimized phenylalanine oxidation. However, increasing the arginine concentration in a diet containing 200 g protein/kg increased phenylalanine oxidation, suggesting an amino acid imbalance involving arginine at this lower level of protein.
