Monitoring livestock

A method of counting livestock comprising pigs or poultry for generating an inventory of the livestock and comprising:

• directing the group of livestock from a first confinement container or pen in which the livestock are contained through a single alleyway to a remote confinement container or pen in a direction of travel so that all of the group of livestock are transferred to the remote location through the single alleyway;
• mounting at least one camera at the alleyway to obtain images of a portion of the alleyway including any livestock in the portion of the alleyway;
• passing the livestock through the portion of the alleyway;
• arranging the portion with a width such that the livestock can pass at least two abreast;
• arranging the portion so that the livestock are free to move in the direction of travel and can turn to move in an opposite direction against the direction of travel before all livestock of the group complete their movement though the single alleyway between the confinement pen and the remote location;
• in a processor carrying out an analysis of the images to generate said inventory of livestock in the group which have all moved through the single alleyway to the remote location;
• wherein the analysis generating the inventory takes into account errors caused by livestock which turn in the portion of the alleyway to move in the opposite direction temporarily before continuing to complete the travel through the portion of the single alleyway to the remote location;
• and wherein the analysis generating the inventory takes into account errors caused animals being side by side when passing through the portion of the single alleyway;
• and forming the inventory into an accounting document.
