Parity differences in the behavior of transition dairy cows
TLDR
The results show how the behavior of primiparous and multiparous cows differs during the transition period, and support the idea that primipARous cows may benefit from different management during this period.About:

Behavioral changes before metritis diagnosis in dairy cows.
Heather W. Neave,J. Lomb,Daniel M. Weary,Stephen J. LeBlanc,J.M. Huzzey,M.A.G. von Keyserlingk +5 more
TL;DR: It is concluded that changes in feeding as well as social and lying behavior could contribute to identification of cows at risk of metritis.

Prediction of calving time in dairy cattle
Mahmoud Fadul,Christopher Bogdahn,Maher Alsaaod,Jürg Hüsler,Alexander Starke,Adrian Steiner,G. Hirsbrunner +6 more
TL;DR: This pilot study revealed that the RumiWatch system is a useful tool to predict calving time under farm conditions.

Lameness and lying behavior in grazing dairy cows.
A.J. Thompson,Daniel M. Weary,José A. Bran,Rolnei R. Daros,Maria José Hötzel,M.A.G. von Keyserlingk +5 more
TL;DR: The results of this research provide the first evidence that the effect of consistent lameness status on lying behavior is associated with rainfall in grazing dairy cows.

Automatic detection of feeding- and drinking-related agonistic behavior and dominance in dairy cows.
TL;DR: It is concluded that data from electronic feed and water bins can accurately estimate agonistic behavior and dominance relationships among dairy cows.

Effect of group size and health status on behavior and feed intake of multiparous dairy cows in early lactation.
Margit Bak Jensen,K.L. Proudfoot +1 more
TL;DR: Investigation of the effect of group size and health on social and feeding behavior of cows during the first 3 d after introduction to a new group suggests that cows experience less competition when moved to a smaller group after calving regardless of health status.

Estimación lineal de los requerimientos nutricionales del NRC para ganado de leche
TL;DR: Linear regression equations have been obtained to directly calculate the nutrient requirements of dairy cattle (TDN, DE, ME, NEL,CP, Ca, P, Vitamin A and Vitamin D) on different physiological stages: maintenance, pregnancy and milk production based on NRC nutrient requirements tables.

Mechanisms that result in large herbivore grazing distribution patterns
Derek W. Bailey,John E. Gross,Emilio A. Laca,L.R. Rittenhouse,Michael B. Coughenour,David M. Swift,Phillip L. Sims +6 more
TL;DR: A conceptual model was developed to demonstrate how cognitive foraging mechanisms could work within constraints imposed by abiotic factors, and preliminary predictions of the model correspond to observed grazing patterns.
Journal ArticleDOI
Impact of changes in organic nutrient metabolism on feeding the transition dairy cow.
TL;DR: Feed intake is usually decreased 30 to 35% during the final 3 wk prepartum, but negative energy and protein balances are not as severe as during the week following parturition, and supplementing fat to transition diets does not seem to alleviate health problems associated with negative energy balance.

Postingestive Feedback as an Elementary Determinant of Food Preference and Intake in Ruminants
TL;DR: From an evolutionary standpoint, mechanisms that enable animals to experience feedback, sensations such as satiety and malaise, should be highly correlated with nutritional well being, toxicosis, and nutritional deficiencies, which are directly related with survival and reproduction.

TL;DR: In this paper, the authors investigated the associations between peripheral blood neutrophil (PMN) function, energy status, and uterine health in periparturient dairy cows.
