Hi Robert,
I have used various animal feed pellets as part of my bulk feed for bream in the past. I once used the 'molassed sugar beet' pellets, which I think you are talking about, and they cost me £2.50 for a 20 kilo sack from an animal feeds mill. I saw the exact same pellets selling in a tackle shop a couple of weeks ago, just repackaged as "revolutionary new carp feed" for almost £4 a kilo!
The animal feed I have had best results with is 'ewenuts' like John mentioned (I think the brand name was Ewebol). The pelletsare very dry and take on flavours well. In the water they break down quickly to just a mush. Looks a lot like brown crumb does on the lake bed, and when fish feed over it, they kick up a nice cloud.
My most successful spod mix for big bream wasa 12kilo bucket, filled half with Ewebol andhalf with 4, 8 and 10mm coarse feed pellets (bought in bulk from the same feed mill) and then I added some salmon / halibut oil and let the pellets soak it in for a few days. The ewebol pellets took on the oil great, and also seem to absorb some of the oil out of the fish feed pellets. I chucked in a couple of tins of shop-bought sweetcorn just beforespodding it in, and fished maize on the hook. Was great for bream, barbel like it too, and I would imagine carp will go daft for it.
