Abstract:
... Knowledge of surface roughness with the consequent presence of crust in the soil is important information for the rational management of environmental resources. Soil surface roughness can be determined by contact and noncontact methods. Contact methods have lower values and precision than noncontact methods. Therefore, the objective of this study was to develop low-cost, portable and robust optic ...
... Adult barn owls and primates possess an almost symmetric monocular rotational horizontal optocollic reflex. In primates, the reflex is initially asymmetric and becomes symmetric with time after birth. The condition in barn owls has not been studied so far. Here, we present data on the development of this reflex in this bird. We tested juvenile barn owls from the time before they open their eyes af ...
... Animal buildings are an important source of particulate matter (PM) pollution. Particulate matter has been known to have both environmental and health impacts and control measures for PM are essential. This study developed a laboratory-scale electrospray system to generate engineered water nanostructures (EWNS), which are highly-charged nano-sized water droplets, and tested the effectiveness of th ...

Abstract:
... The aim of this study was to evaluate the effect of slatted flooring beneath waterlines in broiler barns on litter quality and, subsequently, footpad health. The hypothesis tested was that installing slatted flooring underneath waterlines helps to improve litter quality and thus reduces footpad diseases, enhancing animal welfare as a result. Five experimental runs with two groups were conducted. E ...

Abstract:
... We report the first breeding record of Coragyps atratus (Black Vulture) in Vermont. The birds nested in a dilapidated barn in downtown Burlington, and successfully reared a single chick despite the barn's partial demolition shortly after the chick hatched. This record represents the northernmost breeding record in the US for the species, whose US range has extended steadily northwards in the past ...
... 1. Within a triennial project, 34 layer flocks with untrimmed beaks were examined regularly throughout the laying period to broaden knowledge on the occurrence and development of severe feather pecking and cannibalism, as well as on factors influencing this non-desirable behaviour. 2. Flocks involved 850 to 27,183 hens of seven different genetics, kept in a barn or on free-range systems. Damage to ...

Abstract:
... Goat farming is one of the pillar industries for sustainable development of national economies in some countries and plays an active role in social and economic development. In order to realize the precision and intelligence of goat breeding, this paper describes an integrated goat detection and counting method based on deep learning. First, we constructed a new dataset of video images of goats fo ...
barns, etc ; adults; binocular vision; chickens; eyes; head; Show all 6 Subjects
Abstract:
... Barn owls, like primates, have frontally oriented eyes, which allow for a large binocular overlap. While owls have similar binocular vision and visual-search strategies as primates, it is less clear whether reflexive visual behavior also resembles that of primates or is more similar to that of closer related, but lateral-eyed bird species. Test cases are visual responses driven by wide-field movem ...

Abstract:
... Monitoring cattle for parturition is a labour-intensive task that is often not feasible in extensive environments. On-animal sensors, however, provide a means of remotely monitoring animals, without the labour requirements of traditional observation. This paper explores the use of a rumination algorithm with accelerometer ear tags to observe the changes in rumination around calving. Calving cattle ...

Abstract:
... Dairy cow behavior is affected by external and endogenous factors, including time of year, barn microclimate, time of day and housing. However, little is known about the combined effects of these factors. Data were collected on eight farms in Northern Italy during summer, winter and a temperate season. The temperature-humidity index (THI) was recorded using environmental sensors, whereas cow behav ...

Abstract:
... Laying hens on the free-range systems are susceptible to challenging situations in relation to the rearing environment. Therefore, this work evaluated how solar radiation influences the behavior of laying hens raised in a free-range system, in the Brazilian Savanna. The activities included data collection of meteorological variables and behavioral analysis of 300 commercial laying hens in relation ...

Abstract:
... Wonderwerk Cave, in South Africa, is an exceptional site that has yielded a large collection of small mammal fossils in a stratigraphic sequence reaching back ca. 2 million years. Taphonomic studies undertaken to date, show that Tytonidae (likely Tyto alba) was the dominant predator during the Earlier Stone Age. They produced masses of pellets that formed a dense carpet-like surface that covered t ...

Abstract:
... This preliminary report concerns the micromammalian remains recovered from the Pleistocene strata in Excavation 1 at Wonderwerk Cave by Peter B. Beaumont during the 1980s and early 1990s. Because of the large size of the samples (170 656 specimens representing a minimum of 71 304 individuals), identification has so far only been taken to the generic level. Remains belonging to 34, and possibly 36, ...

Abstract:
... The accurate measurement of environmentally-relevant gases such as ammonia (NH₃) is increasingly important, especially in agricultural science. Accurate and continuous measurement of gases is essential for evaluating NH₃ and other gases as resource-based indicators of air quality in forced ventilation barns and for determining emission rates. To better assess measuring devices under different barn ...

Abstract:
... The conventional intensive system produces cheap and safe chicken eggs, but exposes the animals to stress due to overcrowding on farms. This work compared the ¹HNMR lipidic profile of chicken eggs produced in conventional and free-range systems. Sample preparation consisted of a single-step extraction and centrifugation, and the ¹H NMR experimental time was just 3 min per sample. Eggs from free-ra ...

Abstract:
... The aim of this study is to show that Raman spectroscopy is a sensitive tool, which can be used to analyse eggs obtained in various hens' housing breeding systems. This study provided a new and simple method for testing hens’ eggs breeding systems. Raman methods have the potential to be applied by commercial inspections in the food industry for verification labels placed on eggs. The development o ...

Abstract:
... On-animal sensors are revolutionising livestock farming by automating individual animal monitoring. Rumination is closely linked to cow health and physiology and is a perfect candidate for monitoring using on-animal sensors. The purpose of the current study was to determine if a tri-axial accelerometer ear-tag could be used to detect rumination behaviour in eight multiparous Angus crossbreed cows ...

Abstract:
... Lameness is a common condition in dairy cows. Free-choice access to pasture may benefit lame cows by providing a softer and more comfortable lying and standing surface; however, the effects of this system on lameness have not yet been explored. We evaluated whether a 7-wk period of free-choice pasture access would improve lameness recovery and affect the lying behavior of lame dairy cows. Lactatin ...

... The aim of the study was i) to determine the spatial variability of the skin temperature of dairy cows in a compost system and ii) to evaluate the thermal comfort conditions of confined animals. Skin temperature (Tₛₖᵢₙ,°C) was recorded in three animals at 9:00 am (morning) and the measurement was repeated at 3:00 pm (afternoon) using a thermographic camera (model FLIR i60). Tₛₖᵢₙ data were submitt ...
... This study aimed to better understand environmental heat stress and physiological heat strain indicators in lactating dairy cows. Sixteen heat stress indicators were derived using microenvironmental parameters that were measured at the surrounding of cows and at usual fixed locations in the barn by using handheld and fixed subarea sensors, respectively. Twenty high-producing Holstein–Friesian dair ...
