The Effects Of Social And Environmental Enrichments On Leg Strength And Welfare Of Tomturkeys, Patricia A. Weber
Department of Animal Science: Dissertations, Theses, and Student Research
Two trials (T1, T2) were conducted to determine the effects of enrichment: A) broiler chick addition on early mortality and B) providing environmental enrichments on leg strength and welfare of tom turkeys. Trial 1A utilized 248 1d poults and 8 3d broiler chicks. Four pens of 32 poults were placed for the control. Four pens of 30 poults and two 3d broiler chicks were placed for the trt group. Trial 2A utilized 296 1d poults and 24 3d broiler chicks. Four trts were randomly divided among 16 pens (20 birds/pen). Trt 1 brooders were placed with assistance finding resources. Trt …

Association Between Stall Surface And Some Animal Welfare Measurements In Freestall Dairy Herds Using Recycled Manure Solids For Bedding, A. W. Husfeldt, M. I. Endres
Housing and Confinement of Farm Animals Collection
The objective of this cross-sectional study was to investigate the association between stall surface and some animal welfare measurements in upper Midwest US dairy operations using recycled manure solids as bedding material. The study included 34 dairy operations with herd sizes ranging from 130 to 3,700 lactating cows. Forty-five percent of the herds had mattresses and 55% had deep-bedded stalls. Farms were visited once between July and October 2009. At the time of visit, at least 50% of the cows in each lactating pen were scored for locomotion, hygiene, and hock lesions. On-farm herd records were collected for the …

Dust And Endotoxin In Laying Hen Dwellings, Kristina Matkovic, Marija Vucemilo, Bara Vinkovic
Turkish Journal of Veterinary & Animal Sciences
Only healthy laying hens are capable of producing an average of 280 eggs in 1 year of exploitation. Production of consume eggs takes place in intensive housing systems where the laying hens are still mainly kept in cages under controlled conditions. Technical infrastructure and hygiene quality do not guarantee a production atmosphere completely free from pollutants, including potential pathological risk factors. Laying hens and farm workers are exposed to large quantities of bioaerosols in henhouses. Bioaerosols represent a mixture of different biological particles which can, under certain circumstances, cause health and welfare problems in animals. The most important components are …
