“…Research into animal behavior and welfare has indicated that certain colors might have calming or stressing effects on animals (Hesham et al, 2018). The presence of individuals other than the farmer or a change in the farmer's attire upon entering the poultry farm may elicit fear and panic (Kilgour and Dalton, 1984;Jones, 1987). According to a study, layer hens raised in indoor poultry farms can detect an approaching object from a distance of 25 m (Jones et al, 1981).…”

Abstract. The environment in which animals are kept must provide suitable conditions for their species. This includes ensuring that animals are healthy, well-fed, safe, able to exhibit species-specific behaviors, not experiencing fear or pain, and not under chronic or acute stress. Poultry welfare is achieved when birds are raised in environments that meet their physiological and ethological needs. Fear can significantly impact animal welfare. Chickens have been significantly altered by human artificial selection. Despite this, they exhibit reactivity towards humans and tend to avoid them. Poultry animals reared in environmentally controlled poultry houses and bred for superior productivity are more sensitive to fear factors and have lost their adaptability to a great extent. This study aimed to determine the effect of personnel clothing color on stress and fear in chickens in layer hen coops. The experiment involved 32-week-old laying hens of three different genotypes. A worker in the henhouse wore six respective different colors of workwear (dark blue, green, red, yellow, black, and white), and sound measurements were taken during this time. The results showed that the color of the worker's clothing influenced the sound intensity of the chickens (P<0.05). White clothing elicited the least reaction, whereas black and dark blue elicited the most. The other three colors showed similar reactions. In conclusion, workers in layer hen coops wearing dark clothing, such as dark blue and black, can induce stress and noise in the animals. Additionally, chickens showed similar reactions to green, red, and yellow colors, with white being the color around which they felt the most secure.

“…Therefore, all information related to raising goats and their behavior is essential to ensure their better health care, diets and environment conditions. Hence, knowledge and understanding of goat behavior would also be helpful to raise yield levels, which would provide more income to farmers, milk and meats production for consumers; thus, decreasing the stress on animal and its producer [12][13][14]. The common signs and symptoms regarding to goat health status is essential to be familiar for evaluating that whether goat is healthy or unhealthy, and could also be helpful to recognize clinical signs of certain diseases that are most common in goats.…”

Present investigation was based on isolation and identification of bacterial isolates occurs in blood samples taken from 50 healthy and 50 unhealthy goats during the period from February 2017 to January 2018. A total of 100 blood samples were taken from goats to find out their bacterial burden. Out of these samples, 45 samples of unhealthy goats were found to be infected by several harmful bacteria, which reveals their prevalence as, Enterobacter aerogenes (6.6%), Escherichia coli (8.8%), Streptococcus bovis (8.8%), Klebsiella pneomoniae (11.1%), Cornyebacterium pseudotuberclosis (11.1%), Streptococcus agalactiae (11.1%), Listeria monocytogenes (13.3%), Staphylococcus epidermidis (13.3%), Staphylococcus aureus (15.5%). These bacterial pathogens may particularly cause harmful infections, which could be responsible for economic losses in goat farms, reduction of milk and meat productions enterprises. Therefore, our present work would be helpful in prevention and control of certain diseases that could be transmitted to human by milk and meat products. Moreover, as goat is also an indispensable source of income, therefore our present information may also enable the farmers to become more attractive in goat breeding and enable them in rising yield levels. Furthermore, in many countries, goat blood samples are more readily accessible than the other ruminants, thence have also been used an alternative source of blood for the usage in bacteriological culture media. Our present work is one of very few studies that had investigated the bacteriological analysis of blood samples of goats, and would be helpful for assessing their effects on goat health as well as its consumer's health.

“…Agonistic behaviour and stress-related production losses associated with confinement and mixing are significant challenges to intensive rearing of rangeland goats (Addison and Baker, 1982;Cowley and Grace, 1988;MLA, 2015). In general, goats are more reactive than sheep to a threat or perceived challenge, and they exhibit more exploratory behaviours (Kilgour and Dalton, 1984).…”
