Milk production and milk composition are of prime economic importance for farmers. Thus, as protein volume in feed is increased, not only more milk is produced, bet also threats for environmental pollution are growing. The objective of this work was to establish milk urea content in different...

Weaned calves are the major product from beef cows, and calves live weight is a very important factor that estimate cash prise. Milk from a lactating beef cow furnishes only about 50 percent of the nutrients that a 3-4 month-old calf needs for maximum growth. If the calves nutrient requirements are ...

The study explains the effect of different types of grass forage on the fattening rates of beef cattle. Pure beef breed animal Angus were fed with different types of roughage (chopped or unchopped hay) at three different end stages of fattening (2, 3, or 5 months), and the influence of these...

Dairy by-products - whey and permeate thereof - are widely used in both food and animal feed (including ruminant feed) production worldwide. In the study, which took place from 18 August to 16 December 2020, an experiment was performed with Holstein dairy heifer calves by feeding them milk...

Despite the 50 year old history of fodder feeder use for feeding different livestock species, there are only two sheep farms in Latvia where the automatic fodder feeders are used for feeding of sheep. The research, which was carried out at the farm "Mezoki" at Kuldiga district lasted for eleven...

Deer farming is a new and intensively growing non-traditional livestock industry; therefore, experience in feeding traditional livestock is only partly applicable to captive deer due to physiological and housing differences of the animals. As a result, a number of challenges related to efficient...

Lactation is a factor affecting milk productivity. Recording data was analyzed from 22 first-, 17 second- and 26 third- and older lactation dairy cows. Cows were from different breeds. Data was collected from calving to the 3rd milk recording (average 80th day of lactation). All cows were kept in...

Recent studies show that lactoferrin contribute significantly to the maintenance of udder health. Sadly the concentration of lactoferrin in cow's milk during the middle period of lactation is low. That is an urgent issue - how to stimulate and maintain a sufficient level of lactoferrin in the udder ...

Certified organic dairy farms are one of the most effective measures in terms of climate policy to reduce GHG and ammonia emissions due to the fact that animals are grazed in the summer, manure is composted and the animals are fed mainly with self-produced fodder. However, to achieve the economic...

Precision livestock farming (PLF) can be defined as the management of livestock farming associated with continuous automated, real-time monitoring of animal health, welfare, and environmental impact on cows. The use of sensor technologies can be started in the beginning of cow's life with feeding...
