Heating and ventilation

One of the most common questions among broiler producers is determining how much cooler the birds feel with various amounts of air movement.

Improving bird health, decreasing dust and odour emissions for the neighbours’ benefit and reducing the impact on both the wallet and the ecological footprint by saving of up to 60 % of energy: Big Dutchman has been able…

A hatchery got in touch with me recently about a worrying problem: 3-5% of the newly delivered chicks were dying during their first 3-5 days on the farm. As I arrived on site, chick boxes were being loaded onto a truck a…

With the summer heat settling in, it's not uncommon for ventilation problems to start showing up in tunnel ventilated buildings.

Chickens can cope with a great deal – but rising summer temperatures can increase risk of death by heat exhaustion and suffocation. Here’s how to help your flock stay safe in hot weather

Since the evolution of the hatchery industry from multi-stage to single-stage incubation, Heating, Ventilation and Air Conditioning (HVAC) systems have become an indispensable part of hatchery operations. In essence, the…

A common question we’re often asked as the summer approaches is “where do we start with getting our houses ready for hot weather to ensure our birds remain as healthy and productive as possible?”

With hot weather upon us, it’s time for layer operations to make sure they’re prepared to prevent heat stress. Best-case scenario: We prevent hens from overheating. Worst case: Layers are heat stressed, leading to signif…

A processing plant’s needs differ depending on the market and/or customer product mix. Ensuring tight product specifications (in terms of both target weight and variation) can be difficult to achieve with as-hatched (mix…

High temperatures and increased humidity during summer months are a dangerous combination for poultry flocks from Arkansas and Texas to Maryland and Delaware. Now is the time for growers to take precautions that will hel…

The hatchery is where we create the optimum conditions for life to develop. Although we are talking about the development of embryos, there are many other – unwanted – forms of life, like fungi and bacteria, which can al…

Growers wanting to increase wind speed in an existing building have a couple of different options. Quite often, adding one new high-capacity fan will add enough airflow to boost the wind speed to the desired level. The s…

Ventilation refers to the process by which fresh, clean (normally exterior) air is intentionally introduced and circulated in a poultry house, while stale air is removed. It supplies fresh air that is essential to sustai…

While fans generally get the blame for poor summer ventilation performance, in some cases, it is the evaporative system on the other end of the building that is the culprit. Dirty pad openings can restrict airflow, and u…

This series has been written with the guidelines for a house in a climate that may experience four seasons. As such the series will cover the three modes of ventilation (minimum, transitional, tunnel). In most countries …

Big Dutchman is looking forward to welcoming many guests at the VIV MEA 2020 in Abu Dhabi, March 9 – 11, 2020.

This method is the simplest and most common method for reducing the cubic feet per minute output of fans. A voltage reduction device, called a triac, reduces the amount of voltage to a variable speed motor, slowing the r…
