Weight Gain

With the grass green in many areas and the price for cattle at long last having the potential to provide a better income, there are a number of things that you can do to assist maximum weight gain for your stock.
Step 1 – Satisfy salt cravings
Salt is a mineral and has a role but salt cravings are often the main reason for consumption of supplements being too high. So, if your stock are chasing salt, allow access to it for a while to economically satisfy any craving prior to putting supplements out.
If you have never done this exercise, only buy 1 bag to start with because if your soils are elevated in sodium or your stock drink underground water, then it is likely they will not require any additional salt.
Step 2 – Keep minerals and Phosphorus up to your stock when the grass is green
When there is better quality feed around animals should be growing faster and milking more. This means they will have a much higher requirement for phosphorus because every energy process in the body uses phosphorus in the ATP cycle.
Phosphorus a key mineral for growth and fertility. Recent MLA trials revealed that phosphorus has a relationship with the amount of fodder your cattle will graze and utilise. This equated to increased weight gain while cattle with not enough phosphorus in their diet consumed less feed and put on less weight (see graph).

Over 5 months, adequate Phosphorus intake resulted in 275kg steers gaining 125kg more weight than steers deficient in Phosphorus. At $3 per kg that equates to $375 increased weight gain in 150 days, making the $$$ spent for a phosphorus supplement a great investment.


Every MegaMin blend contains phosphorus to ensure that this essential mineral is always part of your supplementation program.
Step 3. Monitor supplement intake
If stock aren’t consuming enough supplement then the benefits won’t be gained. To monitor how many grams per head your stock are consuming, record the number of stock in the paddock, how much supplement you put into troughs and the number of days taken to consume the supplement. Daily intake can be determined by the following calculation: Daily intake (g) = Kg of supplement/number of days/number of head x 1000.  On the flip side,  if intake levels are too high, then consumption needs to be slowed in order to preserve your daily supplementation costs. Talk to our Field Advisors for advice on this.
Step 4: Consider a soil test
Even if you have no intention of fertilising, a soil test can identify likely deficiencies in pasture and provides a guide for supplement requirements for your stock.
