Vocalizations, in addition to containing biological information of different types, may vary in its structure depending on the stress of the emitter.
The effect of familiarity among dairy cows in their adaptation to the milking group after calving are different in primiparous and multiparous cows.
During the first weeks of life it is the calf’s dam, that in addition to offering food and care for their young, provide them with information about their physical and social environment in order to ensure their survival
Playing could be defined as a set of spontaneous activities, usually associated with pleasure, that do not immediately or directly influence the survival of the animal that practices them. Most of the playing behaviors of growing animals
AUTOMATION
Reducing the production of high producing dairy cows before drying them can be beneficial to health and well-being. Increasing the length of the interval between milkings and restricting energy intake are usually
Monitoring the growth of baby calves provides information on the effectiveness of the nutrition program with which they are being raised and helps control health problems. The main goal of heifer-rearing programs
Lameness is an important source of loss for dairy farms, and producers often underestimate their actual impact, which is estimated at about 35% of the animals
BUSINESS
Milk production per cow in lactation and surface area correlated the best with profitability and this profitability depends primarily on milk prices.
NUTRITION
It was evaluated whether the supplementation with fatty acids in colostrum could increase omega-3 in the blood and thus mitigate oxidative stress.
A diet with milk prior to transport to the grower and shorter transport times reduces body weight losses and helps young calves cope with relocation.
The loss of pregnancy has a negative impact on reproductive performance, resulting in significant economic losses and shortening of the cow's productive life. Between 1997 and 2013, late embryonic mortality has been reported
According to data from the US National Oceanic and Atmospheric Administration, January 2020 was the hottest month on record worldwide in the 141 years climate has been monitored. The surface temperature both for land

Pyrlimicin in waste milk had no effect on resistance to the main types of antibiotics and antibiotic resistance genes to lincosamide.
Springing heifers are one of the most important assets of a dairy farm when it comes to achieve high production of quality milk. That is why it is necessary to ensure udder health in these animals, to make sure that they do not suffer intramammary infections at calving
