Raw materials used in self-mix recipes Self-mix recipes used as a supplements, semi adlib or as full feed, all include a combination of self-produced ingredients and ingredients purchased at a cooperative or feed shop. • When purchasing raw materials for use in selfmix recipes – like maize, chop, sunflower oilcake, soya oilcake, wheaten bran, and dry brewer’s grains – obtain it from a reputable source. Obtain a certificate of analysis where possible. Storage, transport of all feedstuffs including mixing – pellets, meals, roughages and other raw materials excluding silage • All dry or semi-dry feed must be stored in a wellventilated store room or container. • Due to the inherent amount of moisture in all feedstuffs, heat can cause sweating and moisture loss. Pellets sweating can cause a suitable environment for fungal growth and mycotoxin production. • In very humid environments use a dehumidifier when storing dry or semi-dry feedstuffs. • Keep all store rooms and containers rodent, insect and bird free. • Its strongly advised to store all feedstuffs on pallets (or a similar plan), whether in store rooms, containers or under roof (open-air) storage areas, away from direct contact with the ground and walls. The fact that the feed is off the ground, ensures suitable ventilation, but it also prevents any moisture from being absorbed from any surface that may have moisture inherently in it – like cement or on the ground. • It’s advisable not to store roughage and bagged feedstuffs together in a small room or container • Pellet delivery – hot sunny days – Pellets are normally delivered on a truck, and covered by a water-tight tarpaulin. This may lead to some form of condensation – so, when offloading, place the bags in a well ventilated store or container. • When loading any form of feed onto a vehicle, ensure the surface is free from motor vehicle oil, anti-freeze or any other harmful chemical – NB! Keep surface clean. • When transporting feed from one area to another in cloudy weather, cover the feed with a • water tight tarpaulin. • If feed becomes wet, dry it out as soon as possible, this can be fed the next day • If the moisture was only noticed a while afterwards, it will be better to destroy the feed, as it could have started going mouldy. When mixing self-mixed feeds, keep the mixer wagon clean, periodically remove all dirt and feed products caked to the sides, blades and or paddles. • If feed is dusty, it’s a good idea to use one of the following to bind the dust and make the feed more palatable; • Molasses meal (8 to 12%) • Molasses syrup (6 to 9%) • Water as a top up on the lower inclusion of the molasses meal (3 to 6%) if feed gets fed out the same day. • When bagging the feed, and if the feed first gets poured out onto a cement or similar surface, ensure it is free from, motor vehicle oil, anti-freeze or any other harmful or contaminating product. Purchasing and use of feed, and feedstuffs When purchasing any bagged feed, please take note of the manufacturing date. All bag tags should have a manufacturing date and a batch number on them– allowing full traceability. Feed by date and suggestions for use: • It is advisable to try use the feed before its 3 months old. • This will ensure all the vitamins are still available, particularly Vitamin A. • In extreme cases purchased feed can be stored for a maximum of 1 year. • Ensure the feed is stored correctly, in a dry ventilated room. • Supply the animals with supplemental vitamins, added to the animals feed or the drinking water. • Keep some of the bag tags in case a query becomes necessary in the future. • Follow the first in first out approach when using purchased or self-mixed feed, all old feed must be used prior to the new feed being used. 2016 JULY 9
