A method of improving the health of a first group of young monogastric mammals, the first group of young monogastric mammals nursing from a first lactating monogastric mammal during a pre-weaning period, the method including feeding the first lactating monogastric mammal an effective amount of an animal feed during the pre-weaning period, and feeding the first lactating monogastric mammal an effective amount of sugar alcohol during the pre-weaning period.

Various examples are directed to livestock management systems and methods. A first user computing device may display a GUI comprising a first animal visual element. The first animal visual element may correspond to the first animal and indicate a first colostrum feeding of the first animal. When a user selects the first animal visual element, the user computing device may display a first colostrum input screen for receiving first colostrum data. The user computing device may also modify the first animal visual element to indicate the time status of the first testing action for the first animal.

A venting device for an animal feeder which has a feeding teat is disclosed. The venting device has a chamber with an opening into the chamber. A vent opening is also connected to the chamber. A sealing element is retained freely moveable in the chamber. The sealing element has a first surface positioned relative to the opening such that, in use of the feeder, feed in the feeder will contact the first surface and cause the sealing element to move to a sealing position on seat to close the chamber from the vent opening. The surface is configured such that when a negative pressure in the feeder acts on the surface and is sufficient to overcome the weight of feed acting on the surface, the sealing element will be drawn into a position where the chamber can communicate with the vent opening and thereby vent the feeder to atmosphere.

A circular grazing system for poultry and/or livestock. The circular grazing system including a center pivot structure installed at a field. The center pivot structure may have a center pivot axis. The field may be a poultry and/or livestock grazing field. The circular grazing system for poultry and/or livestock may include an enclosure for containing poultry and/or livestock. The enclosure may extend generally radially from the center pivot structure to a circumference of the field. The enclosure may be ratably coupled to the center pivot structure such that the enclosure rotates around the center pivot axis.

A flexible and collapsible liquid storage bag comprising front and back walls formed from a sheet material is described wherein a front wall and a back wall are joined along a perimeter of the bag and are also joined at a joined center portion proximate the centers of the respective front and back sheets. The bags are typically used in the storage, heat-treatment and dispensing of bovine colostrum.
