The effects of feed bunk competition on the feed sorting behavior of close-up dry cows.
The objectives of this research were to describe the feed sorting, feeding behavior, and feed intake of cows consuming a close-up ration and to determine if these behaviors are affected by competition for access to the feed bunk. Thirty-six dry Holstein cows, consuming a close-up total mixed ration diet, were assigned to 1 of 2 treatments: 1) noncompetitive (1 cow/feed bin) or 2) competitive (2...
متن کاملOpioid peptides and behavioral and physiological responses of dairy cows to social isolation in unfamiliar surroundings.
To test whether endogenous opioid peptides are involved in the behavioral and physiological responses of cattle to stress, 12 Holstein cows were either placed in social isolation in unfamiliar surroundings for 15 min or remained in their home stalls, either with or without naloxone treatment, following a Latin square design. Vocalizations (judged as high or low frequency), defecation/urination,...
متن کاملPhysiological and Behavioral Responses of Dairy Cows which Milked with Portable parlor
In normal use, milking parlor can cause the release of oxytocin through neuroendocrine reflex, but the use of milking parlor sometimes cause stress and lead to a decrease in milk production. In Indonesia at this time, traditional milking by hand is still widely used by dairy farmers. The purpose of this study is to investigate the use of milking parlor to the physiological and behavioral respon...
متن کاملTechnical-economic analysis of the combined system power generation, production of fresh water and cooling production
In gas power plants, a lot of energy is lost in the form of heat more than the electricity produced. In the present research, techno-economic evaluation of combined power, desalination and cooling systems running by the exhaust flue gases of a gas turbine in Iran is performed. In addition to using power generated by the gas turbine, attempts were made to use Organic Rankine Cycle to recover the...
متن کاملA comparison of fixed and rotating spray plate sprinklers
A comparative study of two types of spray sprinklers was performed. Rotating spray plate sprinklers (RSPS) and fixed spray plate sprinklers (FSPS) were evaluated individually in open field conditions. The water distribution, wind drift and evaporation losses during the evaluations were measured under low, medium and high wind speed conditions with three nozzle diameters and two nozzle heights a...
