Solutions for Intensive Dairy Farms

We can help you manage effluent waste and find better ways to reuse the end product to help you lower operating costs.

Enhance overall herd health

One of the key threats to cow health is Mastitis. Mastitis is divided into two types– cow-associated and environmental. The bacteria causing cow-associated mastitis usually reside in udder tissue and on teat skin and are most commonly spread at milking. The bacteria causing environmental mastitis survive in the cow’s environment and, although milking may facilitate their entry through the teat canal, the environment is the primary source of infection.

‘Environmental mastitis’ refers to intra-mammary infections caused by organisms that survive in the cow’s surroundings – including in soil, manure, bedding, calving pads, water, or on body sites of the cow other than the mammary gland. Infection of the udder with these organisms is often opportunistic, taking advantage of circumstances that favour environmental contamination and changes in the mammary gland’s susceptibility to infection. There are many bacteria in the environment and some have biological characteristics that enable them to multiply within the udder.
Most cases of environmental mastitis occur within a few weeks of calving, when the cows’ natural defence mechanisms are low and their udders have been in contact with mud and manure during calving. However, exposure of teat ends to environmental bacteria can occur at any time: before heifers have their first calf, during calving, at milking time or in paddocks during the lactation or dry periods.

During lactation, factors that predispose cows to infection with environmental bacteria include milking udders that are wet or dirty or administering intra-mammary infusions if the teat orifice is not sterile. During the early and late dry periods, absence of the keratin plug in the teat canal may make cows highly susceptible to infection.

Bacteria that commonly cause environmental mastitis are Streptococcus uberis or Escherichia coli. Other environmental organisms causing mastitis include other coliform bacteria (Klebsiella species, Enterobacter aerogenes), Pseudomonas aeruginosa,The effective management of cow bedding and the separation of organics is an important function in reducing environmental mastitis and infection.

Reduce environmental impact

The impact of agriculture on Australia’s waterways is a hot topic. Dairy farm runoff containing effluent should not leave the property boundary. There are numerous options in regard to Dairy Effluent Planning, Systems and Equipment available to ensure we are environmentally responsible and do not breach any legislation.

By implementing manure management systems, valuable resources such as water and nutrient-rich organics can be recovered for use on the farm.

Regenerating topsoil

What Does Organic Matter Do for My Soil?

Adding organic material to the soil feeds microorganisms and insects that balance ecosystem of the soil. Organic matter also enhances plant health and growth.

The good organisms feed on harmful microbes, like nematodes and certain soil borne diseases. The beneficial microorganisms also release nutrients into the soil when they die and decompose. So the more beneficial microorganisms that are in the soil, the more nutrients will be in the soil.

How we have helped intensive dairy operations

Central West, NSW

McLanahan installed a Sand-Lane Solution for this client. The purpose of the system is to clean dirty sand bedding recovered from a sand lane at a rate of approximately 54 metric tons/hr. The system removes organic matter from the sand, and deliver a dry bedding at a moisture content of approximately 15% with less than 2% organic matter content.

The end result is a cleaner bedding, greater water recovery and lower sand inventories.

Shandong, China

Located in the Shandong province of China, this customer has 4,000 milking cows on its farm. McLanahan installed a Sand Lane Solution and Sand-Manure Separation System.

Using a front end wheel loader, manure-laden sand bedding is scooped up from the static sand lanes and deposited into the open top hopper. From here, the sand feeds the Sand Manure Separator wash bay where sand is washed free of organic matter.

The separated sand discharges to a Dewatering Screen and is stacked for reuse as cow bedding. The goal is to achieve recovery of sand that is recyclable within a week at a recovery rate in excess of 90%.

This unit can process approximately 50 metric tons/hr. at a sand discharge moisture content of approximately 15% and 2% organic matter content.
