Effects of Feeding Trough on Feed intake of Dairy Cows

The majority of dairy farmers hope that the dairy cows they produce will produce more fresh milk to obtain higher economic benefits. To make milk more milk for the cows, it is necessary to make the cows reach the maximum feed intake. If the feed intake of dairy cows does not reach the maximum, it is impossible for milk production to reach the maximum. The design of the feed tank directly affects the feed intake and milk yield of the cow. The place where cows eat should be as comfortable and convenient as possible. The purpose is to allow cows to eat more feed to consume more nutrients. Only multi-feeding can produce more milk. Therefore, in the process of raising dairy cows, it is recommended to adopt a "fenced-type flat feed trough." This kind of manger is simpler in structure than the traditional elevated manger, and it is cheaper to produce and is in line with the living habits of dairy cows. Cows can eat more saliva as they feed pastures on pastures. According to South Africa's research, dairy cows can produce 17% more saliva than low-level food intake. Saliva has a buffering effect, can adjust the rumen of dairy cows to a suitable acidity, promote food digestion and absorption, and thus can increase the feed intake of dairy cows. According to the results of the United States study, the feeding of Holstein cows using a “planar trough” is 26% longer than the traditional “overhead trough” compared to a traditional elevated trough, and the feed intake time Prolonged can produce more digestive juice, which is conducive to the digestion of food. Another study is to provide dairy cows with two kinds of feed troughs, ie, elevated troughs and flat troughs, for the selection of dairy cows. As a result, cows are willing to feed on flat ground troughs and there is no wasteful behavior of throwing feed. . Cows waste as much as 5% when eating at elevated feeders, and they waste much more in the summer. Therefore, the use of a "fenced plane feed trough" is far superior to a conventional overhead trough. The structure of the horizontal bar feeders: "feeder compartment" refers to the raised partition separating the bed from the feed track, including the feeder compartment septum and the shelf, and the shelf refers to the column that is cast on the hopper sluice and Connect the column's crossbar. The hopper compartment is 63 cm in height from the cattle bed, 48 cm in height from the feed channel (adult cow data); the distance between the columns cast on the hopper sluice is 1.2 m; the column is connected Bars should be installed on the side of the feed channel and 104 cm above the feed path (adult cow data) so that cows can reach farther foods without exerting too much pressure on the hopper sluice and the dividers. Avoid damage to the "feeding compartment". The bottom of the feed trough is in the same plane as the feed trough, and is 15 cm above the floor where the cows stand. Some may add a small raised edge between the bottom of the feed trough and the feed trough to act as another hopper of the feed trough to prevent Dairy cows fodder grass into feed passages, causing waste. The construction size of the horizontal bar feeder shall be determined according to the size of the cow. The following sets of data are provided for builders' reference.
