Thefollowing indicators were studied: 305-day first lactation yield, live weight by first breeding and lactation, cow profitability.The influence of the first breeding age on the subsequent milk production of cows contained in different methods is not confirmed - the difference between the groups ...
The national milk production volume ranged between 30 and 32 million tons annually between 2008 and 2018, but has increased in recent years. Dairy sector in China China is the fourth largest dairy producer in the world and the second largest in Asia. Not only the number of dairy cows is ...
The purpose of this study was to evaluate the complete substitution of dietary grass-clover silage for SP on milk production of dairy cows. Grass-clover mixture was harvested, wilted, and ensiled in bunker silos. The silage was screw pressed in a biorefinery for solid (SP) and liquid (...
Milk production in the United States in 2003 totaled 170 billion pounds, resulting from the tireless efforts of 9 million cows in more than 70,000 dairy herds (USDA, 2004b). Production is concentrated in 20 states, which house 7.8 million cows producing 147 billion pounds of milk. California...
Milk production, milk composition, rate of milking and grazing behaviour were measured for lactating Jersey cows having both the first opportunity to graze (leaders) and also when offered the remaining herbage (followers) from 3-week regrowths of two nitrogen-fertilized tropical pastures, Rhodes gra...

Cows fed whole flaxseed had higher digestibility of acid detergent fiber but lower digestibilities of crude protein and ether extract than those fed ground flaxseed; monensin had no effect on digestibility. Milk production tended to be greater for cows fed ground flaxseed (22.8 kg/d) compared ...
