INNOVATION IN PRACTICE
These challenges underscore the need for more reliable and efficient supplementation methods to en- sure consistent and sustained trace element delivery. Long-Acting Trace Element Supplementation: A Game-Changer Long-acting trace element supplementation involv- ing the use of slow-release bolus technology pro- vides consistent levels of trace elements over an extended period, making them highly effective in addressing the unique challenges presented to Aus- tralian livestock producers. Individual treatments, ensuring each animal is receiving a consistent daily supply of the targeted trace minerals required for optimal animal production. Pacific Biologics are the market leader and now distributes a wide range of nutritional boluses for both cattle and sheep producers in Australia. Utilisation of a long-acting bolus provides peace of mind that the one percenters are getting done, every day. A bolus will continue working for you, even when you stop for the day! Benefits of Long-Acting Supplementation 1. Sustained Nutrient Supply. Long-acting boluses provide a steady release of trace elements over weeks or months, ensuring livestock have consistent, unbroken access to essential nutrients. This reduces the risk of deficiencies during critical periods, such as breeding or peak lactation. 2. Improved Productivity. By maintaining opti- mal trace element levels, long-acting supple- ments improve growth rates, feed conversion efficiency, wool quality, and milk production. Selenium supplementation, for instance, en- hances fertility rates and reduces neonatal mortality in lambs and calves. 3. Enhanced Animal Health. Adequate and con- sistent trace element levels strengthen the immune system, reducing susceptibility to infections and diseases. For example, copper supplementation helps prevent swayback in lambs, while zinc reduces the risk of footrot and skin conditions.
Deficiencies in these elements can lead to a wide range of health issues, including reduced growth rates, poor fertility, compromised immunity, and in- creased susceptibility to diseases. For instance, sel- enium deficiency is linked to white muscle disease in lambs, while iodine deficiency can lead to goiter and reproductive issues. Whilst a deficiency may present as an observable health issue in your animals, sub clinical deficiencies are wider ranging and harder to detect. Grazing animals in regions deficient in one or more trace elements will induce sub clinical de- ficiencies. Failure to address these deficiencies can reduce both production potential and profitability for livestock producers. Challenges in Addressing Trace Element Deficiencies in Australia Australian soils are some of the oldest soils in the world and have been depleted and leached of nutri- ents for thousands of years. Most of our grazing re- gions and pastures lack adequate levels of essential trace elements, primarily due to soil type, climate, and intensive agricultural practices. Deficiencies are most pronounced in regions with sandy, acidic, or leached soils, such as our coastal regions of the northern states and most of our southern animal production areas. Additionally, livestock require- ments for trace elements can vary depending on factors such as breed, age, physiological stage, and environmental stressors. Traditional supplementation methods, such as oral drenches, mineral blocks, and feed additives, have a number of limitations: 1. Inconsistent Intake. Livestock may not con- sume adequate quantities of supplements, especially when offered in free-choice mineral blocks or licks. 2. Short Duration of Action. Many traditional supplements require frequent reapplication, significantly increasing labour input costs and management efforts. 3. Seasonal Pasture Variability. Grazing on de- ficient pastures during specific times of the year can exacerbate deficiencies, leading to production losses and reduced profitability.
