Problems solved by technology

Insufficient intake of various trace elements and vitamins, resulting in reduced resistance to various diseases
At the same time, the uterine pressure is suddenly released, the rumen is empty, leaving too much space for the abdominal cavity, and the suspensory ligament of the abomasum loses its contraction force due to the loss of calcium ions, and is pressed to the left of the rumen, the movement of the abomasum is weakened, and it cannot contract in time Back in place, causing displacement of the abomasum
[0003] At present, domestic pastures often use compound feeding materials such as liquid propylene glycol + calcium propionate to supplement energy and calcium after delivery. There are the following disadvantages: 1. There are many inconveniences in the transportation, storage and use of liquid propylene glycol, and the cost of directly using solid propylene glycol is high; 2. Single source of energy; 3. Poor palatability, can only be taken by gavage, and the operation requires skilled technicians

Embodiment 1

[0043] 60kg of high-energy feeding feed was produced according to dosage 1, and 60 new milk cows were selected in Zhenjie Dairy Farm, Wuqing District, Tianjin. According to the order of delivery date, the cows were divided into a control group and an experimental group by using a completely randomized experimental design. 30 heads per group. The control group was fed with 25 liters of warm water, and the test group was fed with high-energy feeding material once 1 hour after delivery. The postpartum care program is the same, and the prenatal and postpartum TMR are the same.

[0044] During the experiment, the number of cows with postpartum paralysis, retained placenta and postpartum mastitis were recorded.

Abstract

The present invention discloses a compound premixed feed for postpartum administration of dairy cows and an application thereof. The compound premixed feed is composed of vitamins, trace elements, calcium propionate, propylene glycol, a phagostimulant, natural betaine, a rumen regulator and sugar. The added calcium propionate in the product effectively prevents occurrence of postpartum paralysis of the dairy cows; and the added powdered propylene glycol is energy directly absorbed by the rumen of the dairy cows, relieves the postpartum energy negative balance of the dairy cows, prepared by adsorption and mixing of liquid propylene glycol and silicon dioxide in a certain ratio, convenient to use and uniformly mixed. A feeding method is as follows: the postpartum dairy cows instantly administrate once, and then administrated once the other day depending on recovery situation; and each cow slowly administer with an administration device or drink freely after 2 kg of the feed and 25-litrewarm water are mix well. The compound premixed feed is significant in feeding effects, convenient for the source of the raw materials and reasonable in price, and reduces the occurrences of the postpartum paralysis of the dairy cows, retained fetal membranes, abomasums dislocation and postpartum mastitis.

Description

technical field [0001] The invention belongs to the technical field of dairy cow feed, and relates to a compound premixed feed product fed to cows after giving birth, which is suitable for cows within one week after giving birth, and can quickly obtain energy and calcium after giving birth, regulate the rumen, and prevent postpartum paralysis, ketosis, Retained placenta and occurrence of mastitis. Background technique [0002] In recent years, my country's dairy cattle breeding industry has developed rapidly, but there are still some technical difficulties in the breeding process, especially during the critical period before and after giving birth, dairy cows have experienced huge physiological and metabolic changes, and the probability of postpartum diseases has greatly increased. Therefore, dairy cows Before and after farrowing is a key link in pasture management, which has a great impact on the health of dairy cows and the economic benefits of the pasture. Before and afte...
