Three trials were conducted to study the effect of processing method on performance, apparent nutrient and amino acid digestibilities in growing-finishing pigs fed lupine seeds. Ground, expanded or flaked lupine seed was prepared for the trials. In trial 1, a total of 72 growing barrows ($Landrace{\times}Large$ $White{\times}Large$, initial BW of $54.22{\pm}5.87$ kg) were allocated to three treatment diets containing 15% percent of differently processed lupine seed for 28 days. Each treatment had four replicates comprising 6 pigs each. In trial 2, a total of 48 finishing barrows ($Landrace{\times}Large$ $White{\times}Large$, initial BW of $84.40{\pm}6.84$ kg) were subjected to three treatments for 21 days. The experimental design was the same as trial 1 except for supplementation with 20% of lupine seed. Each treatment had four replicates comprising 4 pigs each. To evaluate the ileal digestibility of amino acids, a total of 9 barrows ($Landrace{\times}Large$ $White{\times}Large$), with an average initial BW of $41.07{\pm}1.98$ kg, were fed with ground, expanded or flaked lupine for 7 days. Each pig was surgically equipped with a simple T-cannula fitted in the distal ileum. Amino acid composition and presence of anti-nutritional factors (ANFs) in processed lupine sources were also evaluated. The results showed that there was no significant difference (p>0.05) in lupine amino acid composition due to the different processing methods. Expanded and flaked lupine significantly decreased (p<0.05) the concentration of ANFs compared with ground lupine. There was no effect (p>0.05) on the growth performance in growing pigs. However, processing method had a significant effect (p<0.05) on average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) in finishing pigs. There was no effect (p>0.05) of the different processing methods on the digestibility of dry matter (DM), gross energy (GE), ether extract (EE), Calcium (Ca) and phosphorus (P), but expanded lupine could significantly increase (p<0.05) the apparent digestibility of CP in finishing pigs. Furthermore, expanded lupine had a higher (p<0.05) apparent ileal digestibility for most indispensable and dispensable amino acids compared with ground and flaked lupine. It was concluded that expanded lupine could be beneficial in improving lupine's quality and improve performance and nutrient utilization in growing-finishing pigs.

The effects of monensin, Tween 80 and exogenous fibrolytic enzymes on ruminal fermentation and animal performance were studied in vitro and in vivo. In Expt 1, the effects of the surfactant Tween 80 (0.2% wt/wt, DM basis) on ruminal fermentation of alfalfa, corn and orchardgrass silages were investigated using in vitro gas production techniques. Tween 80 did not affect (p>0.05) cumulative gas production at 24 h, but it reduced (p<0.05) the lag in fermentation of all three silages. With corn silage and orchardgrass silage, gas production rates and concentrations of total volatile fatty acids (VFA) were increased (p<0.05) by Tween 80; with alfalfa silage, they were reduced (p<0.05). Tween 80 increased (p<0.05) the proportion of propionate in total VFA, and reduced (p<0.05) acetate to propionate ratios (A:P) with all three silages. In Expt 2, exogenous fibrolytic enzymes (E; at 0, 37.5 or 75 g/tonne DM), monensin (M; at 0 or 25 ppm and Tween 80 (T; at 0 or 2 L/tonne DM) were added alone or in combination to backgrounding and finishing diets fed to 320 crossbred steers in a feeding trial with a $3{\times}2{\times}$2 factorial arrangement of treatments. The backgrounding and finishing diets contained barley grain and barley silage in ratios of 57.8:42.2 and 93.5:6.5 (DM basis), respectively. Added alone, none of the additives affected DM intake (p>0.1) in the backgrounding or in the finishing period, but interactive $M{\times}T$ effects were observed in the finishing period (p=0.02) and overall (p=0.04). In the finishing period, T without M tended to reduce DM intake (p=0.11), but T with M increased (p=0.05) DM intake. Monensin increased average daily gain (ADG) during backgrounding (p=0.07) and finishing (p=0.01), and this ionophore also improved overall feed efficiency (p=0.02). Warm carcass weight was increased (p<0.001) by M, but dressing percentage was reduced (p=0.07). In the backgrounding period, T increased ADG by 7% (p=0.06). Enzymes increased (p=0.07) ADG by 5 and 6% (low and high application rates, respectively) during backgrounding, but did not affect (p>0.10) ADG during finishing, or overall feed efficiency. Whereas T enhanced the positive effects of M on ADG during backgrounding (p=0.04) and overall (p=0.05), it had no impact (p>0.1) on the effects of E. Interactions between M and T suggest that the surfactant may have potential for enhancing the positive effects of monensin on beef production, but this requires further research.
