••• •• ••• CO L UM N no feed reserves for the winter. • Sell all unproductive animals. • Tax implications and investment options relating to income from the said sales. Objective 3: Feed provision for livestock complement The starting point is to firstly get rid of all surplus livestock. Option 1: Although agave, spineless cactus and old-man saltbush are excellent feed alternatives, it is not readily available. Obtain expert advice regarding the composition of rations. Option 2: Chicken litter is a cheap source of NPN, but not of nutrients. It is illegal to trade this commodity unless the product is registered as animal feed in terms of Act 36 of 1947. Chicken litter may be fed to animals during critical times ONLY and in the following quantities, SHOULD NO OTHER FEED be available: • Cattle: 4.5 – 6 kg/animal/day, or 1% of body mass. • Sheep: 0.5 – 1 kg/animal/day, or 1% of body mass. Take note of the following: • Chicken litter must be of good quality, sterilised and processed. • It is relatively low in protein and not on par with certain other winter supplements. • Energy should be added in the form of grains and molasses. A maximum of 15% molasses can be added - more could result in diarrhoea. • If chicken litter is fed over long periods of time, Vitamins A and E are essential. • Hay / roughage must always be available - chicken litter 48 can’t replace it. • Vaccinate against botulism. • Degeneration of the liver can occur with more than 3kg/ day. • Copper poisoning could occur amongst sheep should excessive amounts be fed. • Milk fever amongst milking cows before calving. • Ionophore poisoning can affect the heart muscle of cattle. • No legal recommendations may be made regarding the use of unregistered chicken litter as feed. Option 3: If it wasn’t possible to plant feed sorghum as grazing fodder, green grazing crops is available to relieve the pressure. Make sure your feed flow program for the year is in place. Consult your seed supplier of choice to establish the availability of feed crop seed and until when it can be planted. Adjust animals gradually to green grazing and make sure that dry roughage is available. Mix your own licks and rations where possible. Make sure that it meets the minimum feed requirements for the specific type of animal. Objective 4: Cover crop to limit wind erosion during the traditional August wind period The main objective is to have cover crop or mulch or material on the field during the traditional August wind period. If it was possible to plant late sunflower or maize, a cover crop will be available. If not, early planting of wheat and/ or sunflower will already help to some extent. The remaining option is any of the small grain or green grazing crops. Feb/Mar 2016 • SENWES Scenario Green grazing crops and cultivars are available, which can be used for a specific purpose, namely: • Serve as cover crops to limit wind damage. • Can be used in a rotation system, which would fit in well with conservation farming. • Can be a source of winter feed for cattle or sheep. The impact of soil moisture and rainfall on the decision-making process Do not plant in soil of which the soil depth and chemistry are unknown. A one hectare crop failure absorbs profits made from approximately four hectares. Should the total soil profile be dry, wait for at le \
