The court entered summary judgment for the bankruptcy trustee, finding pre-petition payments made to the creditor to be preferential transfers. The creditor placed cattle at the debtor's feedlot to be fed out, and was to be paid after the cattle were sold and an amount deducted by the debtor for feed costs. The sale proceeds were deposited into the debtor's general operating account, and the debtor made payments to the creditor and others out of that account. Because the creditor's funds were not segregated, he did not have a bailment, nor was a constructive trust warranted.
