10 Performance Indicators of Cattle Feeding Management in Perinatal Period
Release time:
2019-03-26
Today, we will mainly talk about the nutrition plan and feeding management of perinatal cattle. Now American dairy farmers are experiencing a high price of milk. I hope you can use the information brought today to practice.
Today, we will mainly talk about the nutrition plan and feeding management of perinatal cattle. Now American dairy farmers are experiencing a high price of milk. I hope you can use the information brought today to practice.
First introduce a few definitions:
Pre-dry cow: Prenatal60Tianto21Day.
perinatal cattle: Prenatal21Days to childbirth
Perinatal Cattle: Prenatal21Day to postpartum21Day.
Newly produced cattle: postpartum0To31Day.
Our goal is how to make a smooth transition from pre-to post-natal cattle.
Matters and problems to worry about: the cost of breaking cattle is huge, including the loss of cattle and the loss of milk production. According to MinnesotaTwo.The information shows that,24%The cattle are eliminated during the perinatal period, so the perinatal period is a dangerous period.
Options and Alternatives
1,Maximum antenatal increase in dry matter intake;
2,perinatal feeding straw, mainly wheat straw, can be fed in different amounts;
3,Feeding anionic salt products(control of blood calcium);
4,Postpartum administration of propylene glycol or stress functional package;
5,Prenatal feeding of low lignin corn silage;
6,Feed on bean husk, corn bran or beet pellets;
7,Consider feeding feed additives to aid in perinatal success.
Key performance indicatorsKPI
According to performance indicators to help us to make decisions:。
1Key Performance Indicators#1:
Days of milk production60Days of elimination of cattle below8%. When cows are eliminated after the birth20Elimination within days11%,20-40Days eliminated8%,40-60Days eliminated5%, total is24%If you can lose 2/3, less8%is successful.
2Performance indicators#2:
Dry matter intake in the perinatal pen. Proposed cattle fence>13.6kg mixed cattle fence>12.7kg, first-born cattle perinatal column>11.4kg。
3Key Performance Indicators#3:
Incidence of Postpartum Metabolic Disease milk fever<3%,There are also some people in the United States who think it should be less1%. Ketosis<2%, fourth gastric ectopicDA<5%, the placenta does not go down<8%If premature or twin cows are born prematurely, the proportion of placental wear is higher than this.
4Key Performance Indicators#4:
Postpartum to meet dry matter intake targets.
What factors lead to low dry matter(Energy)feed intake?We are divided into three aspects to explore: first, the rumen is relatively empty, easy to cause the fourth stomach displacement;Secondly, the use of body fat is too large, resulting in ketosis or fatty liver;Finally, the immune function is poor, resulting in mastitis or endometritis.
5Key Performance Indicators#5:
Strategies for the correct use of feed additives. Yeast culture, propylene glycol, calcium propionate, monensin I think it is necessary to add;anion salt(Improve postpartum blood calcium, there are a variety of different products, add a sufficient amount, otherwise can not achieve the effect.)Rumen by-pass choline, rumen by-pass niacin when needed,;And direct feeding microbial need to pay attention to the use.
6Key Performance Indicators#6:
Proper use of irrigation equipment.
The strategy of feeding cattle is divided into four different views:
1 We firmly believe that all cattle should be fed.;
2 selective gavage(Age, parity, current condition, and past metabolic history);
3 Only when solving problems;
4 Never use(Too expensive, too dangerous, too much labor).
Gavage: two ways of gavage,caulk gun,power drench.
Many different irrigation products:
(1)200ml1.4Kilogram filling package, the cost of each filling is from.7.5-62.5From green to orange, dry powder or liquid, etc.
(2)Focus on water, glucose precursors, electrolytes and rumen function promoters.
(3)Do not eat cattle only fed healthy cattle rumen fluid.
(4)Refill if necessary.
a recommended filling material formula:450gram calcium propionate/300propionic alcohol;350Ke YikangXPyeast culture;100grams of potassium chloride;50grams of baking soda;220gram sodium phosphate(Use only when blood phosphorus is low);100grams of magnesium sulfate;50grams of salt.
7Key Performance Indicators#7:
Robust trace minerals program. Include1/4-1/3Zinc and copper use organic;All Selenium Use Organic;mg trace minerals;high dose vitaminsE。
8Key Performance Indicators#8:
Maintain blood calcium levels and avoid hypocalcemia. Subclinical hypocalcemia can increase the risk of endometritis, increase the risk of postpartum fever, increase the risk of postpartumBeta-Hydroxybutyric acid. Causing a longer empty period.
9Key Performance Indicators#9:
Reduces the level of ketone bodies in the blood.
Beta-The negative effects of hydroxybutyric acid on dairy cows are estimated to be30%There is ketosis, which has a significant impact on milk production and reproduction, and subclinical ketosis is a ketone body exceeding.1.2mmol/Liters, if more1.2 mmol/It is recommended to take propylene glycol every day.
10Performance indicators#9:
Reduce stress.
Perinatal population density is less90%;Training cattle to use drinking buckets, etc.;Avoid overswarms;separate herds of first-born cattle;Avoiding large changes in the diet;Reduce cattle picky food concentrate;Managing heat stress;90Cm of forage space.
