“…After separation, however, this approach response dropped to 62%, even though they continued to perform well with true white or red stimuli. The results suggested that, much like humans, when cows are distressed, they exhibit a relatively more negative response bias towards ambiguous stimuli (Daros, Costa, von Keyserlingk, Hötzel, & Weary, 2014).…”

-Domestic cows (Bos taurus) are consumed worldwide as beef and veal, kept as dairy product producers, employed as draft animals in labor, and are used for a long list of other products, including leather and manure. But despite global reliance on cows for thousands of years, most people's perception of them is as plodding herd animals with little individual personality and very simple social relationships or preferences. Yet, a review of the scientific literature on cow behavior points to more complex cognitive, emotional and social characteristics. Moreover, when cow behavior is addressed, it is almost entirely done within the framework of and applied to their use as food commodities. Therefore, there is relatively little attention to the study of cow intelligence, personality and sociality at a basic comparative level. In this review, we examine the current state of scientific knowledge about cows within an objective comparative framework, describing their cognitive, emotional, and social characteristics. Our aim is to provide a more veridical and objective current summary of cow psychology on its own terms and in ways which will facilitate better-informed comparisons with other animals. Moreover, an understanding of the capabilities and characteristics of domestic cows will, it is hoped, advance our understanding of who they are as individuals.

“…They found that when a tone was played with a frequency close to or equal to 4 kHz, rats housed in unstable conditions were slower to press the lever than rats housed in stable conditions, which is consistent with a decreased anticipation of reward. This "pessimistic" judgment bias has since been demonstrated in a few other species (including humans) and situations (Brilot et al, 2010;Daros et al, 2014;Hales et al, 2014;Mendl et al, 2009;Neave et al, 2013;Papciak et al, 2013;Scheele et al, 2013;Verbeek et al, 2014). Conversely, Swan and Hickman (2014) …”

“…Infectious diseases are often considered as the principal cause of calf mortality, specially gastro-intestinal disorders (Svensson and Liberg, 2006;Torsein et al, 2011;Bähler et al, 2012;Daros et al, 2014) and respiratory problems (Gulliksen et al, 2009). Moreover, farms with high calf mortality are regarded as of having poor welfare at the farm level (Ortiz-Pelaez et al, 2008;Kelly, 2013).…”

IntroductIon Livestock is an inherent element of the compound farming system in Bangladesh as it besides a source of meat and milk protein, a prime source of farm power services as well as employment. The livestock sub-sector dispenses 20% and 50% of the total population a full time employment and part-time employment, respectively. The contribution of the livestock sector to total gross domestic product persisted steady within a range of 2.1-3.6% over the 1973-2008 periods. Despite a steady contribution to the Gross Domestic Product (GDP), budget allocation for this sector remained <1% of the total expenditure. Moreover, it was revealed that the growth in individual livestock products were mainly in minor products (e.g., tails, bones, etc.) and hides and skins (a major export item) rather than in milk and milk products, meat and eggs might not be very motivating because such tendency will lead to less imresearch Article Abstract | A survey was conducted to characterize calf management and hygiene practices adopted by dairy farmers at Chittagong, in Bangladesh. A total of 210 dairy farms located in 3 geographically distinct regions in Chittagong division, namely coastal, hilly and plain area, were surveyed. Calf management and hygiene practice related data was collected through a standard questionnaire and all sampled farms were visited once by technical persons and administered the questionnaire by 'face to face' method during the period July, 2015 to May, 2016. Statistically significant variations were observed in distribution of different factors through different strata (herd size and region). Among larger farms (>50 cows), 10% had a poor hygiene score whereas 32% of the smaller farms (5-20 cows) belonged to this category. 97% of the large farms used tube well water as the source of drinking water for their calves; whereas 35% of the small farms used surface water. None of the large and medium farm owner said they never clean the calf pen; 47% small farm owners said yes to it. More than half of the smallholders (54%) were discovered with raising other domestic animals and birds within the same premises. Hygiene score and surrounding environment of the farms did not show any regional variation (p>0.05). Remarkably 65% farms of the hilly area used surface water for their calves to drink with. The relationship between management practices and calf mortality/morbidity is complex. Our study design did not allow us to draw conclusions about the management and hygiene practice responsible for calf mortality/morbidity, but knowing the management practices adopted on farms is valuable for bringing attention to herds with less optimal practices and for planning meaningful experiments to explore causal affects.
