Positioning Yourself for Profit – The KEY = Phosphorous Supplementation

What are the key areas in red meat production that drive profitability?

1.Weaner weights

2.Optimal utilization of your cheapest feed source, namely natural pastures

3.Marketing at the right time, in the right place at the right price, but it is only possible if you do have animals to be able to market...

4.In this article, we want to look at the impact that the right phosphate supplement has on the above key areas that drive profitability.

Phosphate supplementation is too expensive: right or wrong?

The perception exists that phosphorous supplementation is too expensive, but in reality, it's more expensive not to supplement it. The statement that a phosphorus deficiency adversely affects animal performance, has been made on occasion by the late Dr. Jasper Coetzee.

If, after phosphate supplementation and even supplementation are generally viewed from a return on operating expenses perspective, supplementation makes so much more economic sense in sustainable animal production. In most cases, a farmer can tell you very soon what his supplementation account was the previous year, but because the return on capital was spent, in the case of supplementation, hidden or even hiding away in the everyday operating expenses, phosphorus supplementation is not necessarily seen as an investment paid out on the day of marketing. Even incorrect marketing choices can impair this investment's return. Therefore, it is important to look again at the profit after supplementation costs, excluding the other factors, which sometimes shows out of focus.

The following graph of local research data of Feedmaster, which was again adapted to the latest market prices in January 2020, shows the profit to supplementation costs, as well as an improvement in profitability of 42% if phosphorus supplementation is done, as opposed to just providing a salt lick supplement.

In terms of the actual cost of phosphate supplementation, producers easily make the mistake of just seeing the bag price. However, if one considers the low intakes, as well as the profit after supplement cost of phosphate, you realize you actually shot yourself in the foot, by trying to save on the Phosphate, and in doing so, not keeping your feed troughs stocked.

Below the reality of phosphate costs per herd unit and sheep unit per day.

The reality of low intakes may also be explained as follows;One head of cattle will feed almost 1 year on a bag of P6 and one sheep or goat will feed about 3 1/2 years on a bag P6.

The economic impact of Phosphate deficiencies

It is impossible to over accentuate the importance of phosphorus in red meat production, especially in cattle. Looking for effective growth in our animals, we are talking about effective energy metabolism in the body of the animal. For effective energy metabolism, the body needs enough phosphorus molecules in the electron transport chain for optimal energy transfer. The illustration below shows how the metabolism of protein, starch and fat, joins and ends up in the electron transport chain where the phosphorus molecule is essential for optimal energy transmission.

Phosphorous, therefore, plays an extremely important role in the conversion of grazing energy to usable/growth energy. The most severe result of a phosphorus deficiency is a reduced pasture intake that remains a producer's cheapest feed source. This reduced intake leads to stunted growth, poor reoccupation due to poor condition count of breeding stock, anestrus and reduced milk production that once again has an effect on our animal's weaner weights.

Lower weaner weights during weaning, causing the wrong marketing choices to be made as well. It again impacts the profitability of the production system and has an impact on calves being marketed. This means that due to a lower income per head, they should be withheld until weights are legal, which will again cause marketing outside of the traditional weaner calf auction season when there is not enough competition among the buyers. Prices are usually also lower and not competitive. Calves must even be assisted with unnecessary supplementary nutrition after weaning that also eats into the profits. In this case, it is not referred to as a specific management system. Creep feeding promotes increased growth and profitability, especially when weaner calf prices rise when it makes even more sense to give creep feeding.

To address the benefits of optimal energy metabolism, we can also refer to research done, which has shown the difference in pregnancy in animals that were in a positive energy balance towards animals that were in a negative energy balance during mating. There is a significant improvement in re-conception the moment the animals were paired during a period of positive energy balance towards a negative balance, where the animals lost condition during mating.In sheep where stimulus feeding is more commonly known, we see even a more drastic improvement in pregnancy presentation and especially higher fecundity or in laymen’s language, increasing in the number of twins or more born.

Are all phosphate resources the same, and if not, what economic impact does it have?

The bio-availability and quality of phosphate sources used in the mix of Phosphate supplements have been placed under a magnifying glass in nutrient circles in the past and research on these resources has provided interesting facts. From this, we can conclude that the traditional use of P18 (DCP) sources is disappearing and P21 and P23 (MCP) sources that have a 1:1 calcium to phosphorus ratio and also a lesser degree of interaction between the available phosphate and calcium are rather used.

-The table below illustrates the decline in bio-availability. This information is gained from a presentation done by FeedFirst Animal Nutrition Consultants in the RSA.


What is even more interesting is the absorption percentage of each of these sources.- It will definitely be beneficial to the farmer financially, to ask the feed manufacturer of what resources they make use of, so that he/she does not pay for phosphate that is not advantageous for production. Below is a table from the same presentation that highlights this:

With the positioning of Futterfos in the market, Feedmaster has also done everything in their power to obtain a mono-calcium phosphate source with 23% phosphate, which is certainly of the best digestibility %. In cases where the exchange rate is unfavorable, Feedmaster also makes use of the best P21 sources in the RSA. The use of lower digestible di-calcium phosphate (P18) sources, does not occur in Feedmaster's phosphate.

A good Phosphate supplement does not only provide Phosphate to the animal but also a wide range of micro minerals which is also essential for optimal production. -However, it remains of paramount importance that the micro-minerals used in a balanced relationship, are supplemented.

This famous illustration shows the possible interactions that can occur between minerals.

Futterfos has been formulated to meet more than just the 25% legally prescribed needs and therefore has a higher mineral specification than the normal P12 products in the trade, based on 25% of need. Traditional Phosphate supplement levels provide only 25% of the animal's daily needs, according to the requirements of law 36/1947. However, the latest research shows that higher supplemental levels pose greater benefits for animals, as well as farmers.

Latest research and the next step forward.

Research that is new to the bio-availability of phosphate, and which for Feedmaster also establishes a new dimension for sustainable improvement, is the coupling of DCAB (Dietary Cation-anion Balance) values for all supplement products.

-The latest research, which was shared with us as recently as December 2019, on a Farmers ' day near Grootfontein, highlights the effect that positive and negative cation-anion balance has on the absorption of phosphorus and calcium from the bone of an animal. For example, many farmers make the mistake of adding unnecessary sulfur to their licks, making the Cation-anion balance of the supplement, which starts a biochemical reaction that activates the absorption of phosphorus from the leg. Along with phosphorus absorption, calcium absorption is also taking place. This causes a significant reduction in bone density which results in symptoms such as osteochondrosis and an increase in bone fractions.

Many feed companies also experience this problem, by not necessarily pursuing quality, but only go for the lowest cost of sales and then purchase raw materials which quality is not on par.

Dr. Kenneth Botha of Nutrigenics, who was part of this research project and who also presented the lecture in Grootfontein in December 2019, showed some examples of phosphate sources that contained high sulfur levels. If these raw materials that are suspicious are used, it can quickly change the cation-anion balance that accelerates this withdrawal from the leg. There are several other factors that also contribute to the final balance of the ration that the animal consumes daily and this includes, for example, chlorine and sulfur levels of borehole water, the water quality of earth dams, as well as of the pastures. If precision farming is the path you take, it will be good to do at least water analyses of your most important water sources to see if there are certain elements that may have a major influence on the total ration's cation-anion balance. Definitely, one of the largest responsibilities of your animal feed manufacturer and this is also why Feedmaster is proactive to ensure that the product we develop and manufacture, does have a DCAB value on the bag ticket for transparency and that our supplement range meets the right balance for our producers to ensure peace of mind. Unfortunately, these changes are not yet part of Act 36 's requirements, which entails that there can be products with a negative DCAB at a possible cheaper price than a balanced product. This is where sufficient information should be transferred to our producers, in order to enable them to at least make the right decision that will ensure economically the most benefit to him/her.


Research results show that calve percentages were 80% compared to 51% of the control (no phosphorus supplementation), as well as an increase in calving weaner masses of up to 27.5%, were reported due to the supplementation of phosphorus in phosphate deficit areas (Read et al., 1986a, B). In the current difficult economic times, no farmer can afford not to unlock this advantage. This is a basic farming principle that only ensures benefits to the producer.

It will also be wise, to look twice at the contents of a bag of phosphate before you buy it, to make sure the product is what it needs to be and that you get the full return on your "investment" that you had in mind when you made the purchase.
