The digestibility of different vegetable protein sources were investigated and the effects of supplementing canola meal (CM) as partial inclusions were studied in growing pigs, to determine the performance parameters and its economic importance. In Exp. 1, four pigs (average initial BW = 15.4 ± 0.35 kg, 5 weeks of age) fitted with simple T-cannula at terminal ileum, were fed four diets following repeated 4 × 4 Latin square design having adoption period of 7 days. Diet 1 was Nitrogen free diet containing corn starch. Diets 2, 3, and 4 were the basal diet supplemented with soybean meal (SBM), rapeseed meal (RSM), and domestic CM respectively. The AID of crude protein was decrease in RSM in comparison to SBM supplementation. The AID of Dietary indispensable amino acids (DIAA) such as Lys, Meth, Pha, and dispensable amino acid Ala, Pro, Asp were decreased (P < 0.05) in RSM supplemented diets. The SID of DIAA does not differ but the SID of Asp was higher (P < 0.05) in RSM and CM diets while SID of Pro was lower (P < 0.05) in RSM in comparison to SBM supplemented diets. In Exp. 2, 192 growing pigs (average initial BW 24.76 ± 2.55 kg) were randomly allotted to four dietary treatments with increasing levels of CM i.e. 0, 3.75, 7.50, and 11.25 % respectively. Diets were fed in meal form for 35 days. Increasing CM levels in diets had no effects (P > 0.05) on growth performance and apparent total tract digestibility (ATTD) of nutrients and energy. Total weight gain, total feed intake, and feed cost per kg weight gain were not affected by increasing levels of CM in diets but total feed cost (TFC) per pigs was linearly reduced (26.463 to 25.674; P < 0.05). Broadly, the AID, and SID of amino acid was reduced in RSM but was not effected in CM in comparison to SBM supplemented pigs. Moreover, increasing levels of CM in pigs diet had no effect on the ATTD and performance but TFC per pig was reduced. Thus CM inclusion of up to 11.25 % in diets can be used for reducing the production cost in growing pigs without any negative effect.

Aims: Treatment of Liver metastasis of colorectal cancer (CLM) is now evolving rapidly with regards to oncological and technical resectability. Little is known about multiple CLM with tumor thrombus in the portal vein (PVTT). On the literatures, Authors suggested at least that macroscopic PVTT is not a contraindication to liver surgery. Herein, we report the clinical outcomes of two patients with progressive PVTT and multiple CLM underwent hepatectomy. Results: Case 1. A 73-year-old man presented with a metastatic liver tumor accompanied by a macroscopic tumor thrombus in the right portal branch and multiple CLM on both lobes. Extended right hemi-hepatectomy with and removal of the tumor thrombus were performed, and the liver metastasis and tumor thrombus were successfully resected. The patient had the multiple CLM on remnant lobe with left main PVTT at 8 months after the liver surgery. Case 2. A 64-year-old woman who had previously undergone palliative chemotherapy for ascending colon cancer presented with CLM accompanied by a macroscopic tumor thrombus in the left portal branch. Tumor and PVTT were progressed regardless of various chemoagents. Left hemihepatectomy with radiofrequency ablation on right lobe and right hemicolectomy were performed. But, CLM occurred just at 3 months after the liver surgery. Conclusions: The prognosis of patients with liver metastasis accompanied by a PVTT remains unknown. Considering previous our cases, a poor prognosis may be expected even though the tumor is successfully removed by liver resection. We introspected whether surgery is the treatment option for such pattern of liver metastasis in this era.
