Trimming hooves Trimming hoof hooves once a quarter, correcting unfavorable hooves, and increasing the daily milk production by 1 to 2 kilos.
Feeding oyster shells and sunflower seeds Oyster hulls and sunflower seeds are rich in protein and fat, adding 10% to 20% to the feed, and the milk production of dairy cows can be increased by about 15%.
Feeding sweet sorghum According to experiments, feeding sweet sorghum to dairy cows produces 0.5 to 1 kilograms of fresh milk per day than feeding corn.
Feeding citrus leaves to ferment cows after fermenting citrus leaves can increase milk production by about 30%. The method is to collect the citrus leaves in the early spring, wash them and chop them, then mix them with a small amount of beer as a starter, put them into the reservoir, and ferment for 10 days.
Carotene was added 30 days before milking and 92 days after milking. Adding 7 grams of carotene to the diet will increase milk production by 200 kg per head during the lactation period.
Feeding the fish and shrimp into the diet of each cow was mixed with 0.3 kg of cooked small fish and shrimp, which could increase the output of fresh milk by 2 kg per day. If, at the beginning of lactation, 0.75 kg of fishmeal was added daily, the daily output of fresh milk could increase by 1.5. About kilograms.
The pressure of the gas
piston through the connecting rod to the crankshaft, realize the change from
heat energy to mechanical energy.
The work condition is very bad, and the
temperature of 1400-1800 DEG C, and pressure
Up to 13MPa above the gas
contact, greatly alternating thermal stress and mechanical stress.
And by the
serious corrosion of gas, and under the condition of boundary lubrication and
cylinder wall friction and strong impact 1 times.
The piston in high
temperature, high pressure, strong corrosive gas contact so that it has enough
strength and hardness,
Heat resistance and good thermal resistance, high
fatigue strength and corrosion resistance. For high speed diesel Engine Piston
also requires light as far as possible.
In order to reduce the inertia
force.
Marine piston large low speed diesel engine of the crosshead is
usually combined.
The heat treatment process by normalizing and annealing,
and iron pearlite are ferrite organization, has good heat resistance.
Piston
alloy quenched and tempered steel has better heat resistance and corrosion
resistance. The skirt with nodular cast iron annealing treatment, with good wear
resistance.
There are new tricks for increasing milk production
Feeding congee to cows to feed congee can increase milk production by 31% over dry and wet feeds. When processing porridge, first add a little salt to the powdered concentrate, mix it with a small amount of water, and pour it in when the water in the pot is boiling. Stir for 5 to 10 minutes.
