AGRICULTURAL Dry season supplements Where are the hurdles? The use of dry season lick supplements is a scientifically grounded practice applied by most producers over many decades.  Deur Phillip Lee Hinterland Manager: Animal Farming Solutions T he production and reproductive benefits for the animal, as well as the economic benefits for the producer, have been proven in many scientific trials - the catastrophic consequences of an inadequate lick strat- egy for animal and producer have also been highlighted numerous times. The cost squeeze which is becoming progres- sively worse makes it essential to focus increasingly on being more effective in respect of lick strategies. There should be no doubt amongst producers regarding the benefits of strategic lick supplements, particularly against the background of the evidence in favour of strategic lick supplements. This article will not focus on the advantages and disadvantages of specific products or on the different practices, such as home blending ver- sus shelf products, but rather on certain seasonal hurdles, which are often missed and which can sink the objective of a lick programme, despite the correct product choice and practice. SEASONAL HURDLES One of the hurdles which needs to be high- lighted is the perception that winter arrives gradually and that we have time on our side. This is often not true - in fact, the win- 44 SENWES SCENARIO | SPRING 2018 ter is unforgiving and drastic. The decline in the nutritional status of our grazing (particularly in respect of protein) during the winter months is very sudden. We have to be prepared for this and ensure that we adjust our lick strategy timeously in order to compensate for the decline in the quality of the grazing. It is true that no two successive years are the same and for this reason we cannot decide from year to year to switch over to winter licks on a specific date. It requires sharp observation on the side of the producer. The second and possibly even more significant hurdle is that our winters are actually longer than what is generally accepted. Our winter period starts earlier and ends later and the biggest danger is that we are inclined to compare our “human” seasons with those of animals. In many parts of the country we are techni- cally in a winter period in March already, although the day temperatures are still relatively high, but we see that the protein offering of the grazing already does not meet the protein requirements of the ani- mal. When we pack away the winter jack- ets and blankets at the end of September/ beginning of October and enjoy the arrival of “summer”, it is the climax of winter in the world of the animal. Take care not to withdraw winter licks too early, when the requirements of the animals are at its highest point. A further hurdle to be highlighted is to not overstate the contribution of our natural resource offering (grazing). No lick strategy can compensate for a poor resource offering and when licks start to replace grazing, it becomes a very expen- sive exercise - not only in terms of high lick costs, but also in terms of losses due to sub-standard animal performance. A conservative approach to the nutritional status of grazing and concomitant stock- ing rates should therefore be followed, particularly late in the dry season, when not much grazing is available. In practice we still see that not enough licks are put out and that good lick strategies are often made undone due to the fact that animals are not taking in the recommended lick quantity. Research indicated that, in cer- tain instances, up to 25% of the animals are not taking in the correct lick quantities and 10% of the animals do not take in any lick due to competition. It is evident that successful dry season lick supplements are not only based on the choice of the correct product with the correct composition to supplement critical deficiencies in an economical and stra- tegic manner, but also on a clear under- standing of the season in which we find ourselves, and more importantly, a clear understandi
