Be spot-on when sinking a borehole
Stockfarm|March 2020
Water is a scarce resource in South Africa and identifying the right place to drill for it, is often difficult. Several factors must be considered, as the cost of a borehole is extremely high.

Be spot-on when sinking a borehole

According to Gert Nel, a geohydrologist at SRK Consulting, there are unfortunately no shortcuts when it comes to locating water. “Geology and rainfall are mainly responsible for the occurrence of abstractable groundwater. Science does not conform to the methods employed by traditional water finders. Water finders are also often guided by the experience they’ve gained in a specific area (geology).”

Do it scientifically

He explains that using scientific methods to locate water always starts with a study of the specific area. “We will assess databases of boreholes in the wider area. This teaches us more about historical successes and failures. The information is compared to the geology and geological structures in the area, so as to filter it.”

A dry hole does not necessarily mean that the area has no water; instead, it can indicate that the borehole was sunk in the wrong place. A geohydrologist who is convinced that he understands the geology of the area, will choose areas that can be drilled using geological methods to ensure the best chance of finding water.

Feed Additives: A Veterinary Perspective

In an already volatile environment, dairy profit margins vary as milk prices and feed costs shift annually. Feed costs represent the largest input cost (an estimated 35 to 70% of the variable cost) in the production of milk. As a group of feed ingredients, feed additives can cause a desired physiological response in a non-nutrient way, such as pH shift, growth or metabolic modifier, and will usually be cost-beneficial.

Tips for a successful AI programme

The success of an artificial insemination (AI) programme depends on several factors that are largely within the control of the producer. It is interesting that those producers who take a hands-on approach to their cattle and inspect them regularly are also the ones who achieve the greatest success. Before his passing, Stockfarm spoke to Koot Louw, a well-known reproduction technologist from Brandfort in the Free State, about his insights into and advice regarding the AI process.
