“…Doubts about a clear-cut distinction between agonistic ('bad') and affiliative ('good') behaviours are not new. The concept of dominance was questioned before, highlighting the complexity of agonistic interactions in dairy cows (Val-Laillet et al, 2008), and the idea of including positive social interactions as a positive indicator of good welfare repeatedly failed because of lack of clear interpretation, rare occurrences and/or poor repeatability (Boissy et al, 2007;Knierim and Winckler, 2009).…”

“…Many animals compete with conspecifics to gain better access to food, shelters, mates and other resources (Rowell, 1974;Drews, 1993;Barroso et al, 2000;Petrulis et al, 2004;Burmeister et al, 2005;Gherardi, 2006;Hovland et al, 2008;Izawa and Watanabe, 2008;Val-Laillet et al, 2008). This competition, which is common among gregarious animals (Drews, 1993), often involves agonistic behaviors, such as aggressive physical acts, as well as ritualized behaviors, which may include signals used in communication.…”

SUMMARYDecapod crustaceans, like many other animals, engage in agonistic behaviors that enhance their ability to compete for resources with conspecifics. These agonistic behaviors include the release of chemical signals as well as physical aggressive and submissive behaviors. In this study, we report that Caribbean spiny lobsters, Panulirus argus, use both urine-borne chemical signaling and physical aggressive behaviors during interactions with conspecifics, and that these agonistic behaviors can influence the behavior and eventual social status of the interactants. Spiny lobsters that engaged primarily in physical aggressive behaviors became dominant, whereas spiny lobsters that received these physical aggressive behaviors responded with avoidance behaviors and became subordinates. Dominant animals frequently released urine during social interactions, more than when they were not in contact with subordinates and more than when they were not paired with another animal. Subordinates released urine significantly less often than dominants, and no more than when not paired. Preventing release of urine by catheterizing the animals resulted in an increase in the number and duration of physical interactions, and this increase was primarily driven by dominants initiating interactions through physical aggressive behaviors. Introducing urine from one of the catheterized animals into an aquarium reduced physical aggressive behavior by dominant animals to normal levels. Urine-borne signals alone were capable of inducing avoidance behaviors from solitary spiny lobsters in both laboratory and field conditions. We conclude that urine serves as a chemical signal that communicates social status to the interactants. Ablation experiments showed that that these urine signals are detected primarily by aesthetasc sensilla of the olfactory pathway. Supplementary material available online at

“…According to HAFEZ & BOISSOU (1975), the interactions between bovines result in hierarchical relations, in which, through disputes, the subordinate-dominant order is established. VAL-LAILLET et al (2007), working with lactating dairy cows, found a longer time at the trough of cows with a high value in dominance ranking in the first 120 minutes after the feeding.…”

Nitrate/nitrite poisoning in dairy cattle from the Midwestern Minas Gerais, Brazil

2017

In a rural property of the Midwestern Minas Gerais, Brazil, three 2.5 to 3-year-old female bovines (7/8 Holstein x 1/8 Gir) weighing approximately 380kg died after showing brownish colored mucosa of conjunctiva and vaginal vestibule, gray-bluish tongue, dyspnea, sialorrhea, tympany, and progression to sternal decubitus and death. In the macroscopic evaluation of one of the bovines, dark (chocolate-colored) blood of difficult coagulation, and intensely cherry-red skeletal and cardiac musculature were observed. Beyond that were observed brownish lungs, kidneys, liver, and encephalon, and all the stomach compartments were dilated due to large amounts of gas. In addition, the carcass exhaled a nitrous odor. The diphenylamine test and the nitrate dosage in the forage (Pennisetum purpureum, “elephant grass”, Napier grass cultivar) used in feeding the bovines showed a high concentration of nitrate, allowing the diagnosis of nitrate/nitrite intoxication. The main factors leading to the poisoning were attributed to excessive fertilization of grass with bovine manure, the occurrence of a drought period followed by a rainy season, lack of adaptation of the bovines to a nitrate-rich diet, and a diet composed almost exclusively of elephant grass. This is the first report of spontaneous nitrate/nitrite poisoning in cattle in southeastern Brazil.
