The amount of trough space available when providing watering facilities or feeding livestock significantly influences the performance of livestock. Drinking troughs warrant special attention because an excessive amount of water is wasted when troughs are cleaned regularly, as is necessary for good management. Furthermore, poor design results in animals falling into troughs and drowning. It is not uncommon for cattle to fall onto their backs in a trough and die if they cannot get up. Water trough design must take the following into consideration:
A feed bunker is a trough or bunker in which the feed is placed for the animals to feed on. Good feed bunk design is essential to optimising DM (Dry Matter) intake. Cattle should have 60 to 75 cm of bunk space each to allow all of them to feed at the same time. The feed bunk or feed pad should be 10 to 15 cm higher than the alley where the cattle are standing. Cattle consuming feed at ground level waste less feed.
In addition, the condition of the feeding surface can also affect DM intake. Feed bunks must have smooth surfaces. Surfaces without grooves or holes that can trap feed are easier to clean and help reduce the build-up of waste feed, mould growth and odour.
Another important factor is to avoid muddy conditions and manure build-up on feed bunk aprons. These conditions can decrease the palatability of the ration as well as increase the transmission of disease.
Feed and lick troughs can be made from almost any material. Inverted rubber tyres have become very popular because they do not rust and cannot cause injury to animals, are cheap and readily available.
Prior to the start of feeding, animals must be grouped according to the size of the animal and age group. By dividing livestock into production groups, feeding is simplified because each group can be fed a ratio suited to its requirements. Separating animals into groups overcomes the problem of larger animals dominating at feed troughs and preventing smaller animals from obtaining their allocation of feed. Especially where feed is rationed, adequate trough space is essential to prevent smaller animals from losing mass and condition, while larger animals get over fat.
Where trough space is limited, cattle can cause damage to troughs or turn them over when they butt each other in an effort to reach the food. Damage to troughs and the loss of food is reduced if troughs are firmly anchored to the ground.
