The present study was conducted to assess animal welfare status of broiler chickens raised in conventional and welfare-certified farms. One farm (30,000 birds/house, 1,488 m2/house, 2 houses) one (32,000 1,920 were selected measure productivity, stress responses, indicators 3 flocks (2 farms/season, n = 6 flocks/farm type) during summer, autumn, spring. Upon visits, body weight, uniformity, (i.e., fecal feather corticosterone, footpad dermatitis, hock burn, dirtiness, gait score) measured at...

As animal welfare becomes more active in livestock industry, research is being conducted on ways to improve poor housing environments, reduce stress, and meet standards. Among these, environmental enrichment methods are effective reducing stress creating a welfare-friendly rearing environment, but there few cases of actual application farms. Therefore, we aimed investigate the effect providing pecking materials (grain blocks), known as one methods, commercial broiler This study used two...

The objective of this experiment was to investigate the effects dietary supplementation rice bran oil (RBO) on growth performance, blood parameter, and immune response in broiler chickens.A total 240 1-d-old ROSS 308 male broilers were randomly allotted 4 treatments with six replicated pens consisting ten chicks. basal diet formulated be adequate energy nutrients. Three additional diets prepared by adding 5, 10 or 20 g/kg RBO diet. experimental fed an ad libitum basis birds during 35...

We investigated the effects of feeding different levels crude protein (CP) on broiler performance, blood characteristics, meat quality, nutrient and nitrogen (N) availability, stress levels, welfare indicators in a environment. A total 625 eight-day-old male broilers were assigned to five dietary CP (control (CON) 1-4% reductions) during grower (8-21 days) finisher (22-35 periods. The CON diet contained 20% phase 19% phase, while all birds received 22% starter period (1-7 days)....

The aim of this study was to identify the feather section, among whole feather, rachis, and vane, with highest reliability for corticosterone measurement in 10 Pekin ducks aged 42 days.

A total 600 68-week-old Hy-Line Brown hens were randomly assigned to 1 3 dietary treatments, repeated 5 times: Mash type basal diet, diet an premix (1.0 g/kg), (1.8 g/kg). The results showed that strength was higher (p &lt; 0.01) in group than groups. Further, levels Fe Mn liver 0.05) groups group. concentrations Mg spleen different among...

Stocking density is a crucial parameter that impacts animal welfare, performance, and economic returns for producers. In our current investigation, we explored the influence of stocking on growth litter quality, footpad dermatitis, corticosterone concentrations in broiler chickens. Low high densities were defined as 16.7 birds/m² (certified n = 32,000; initial BW 42.11±0.32g; Arbor Acres) 20.3 (commercial farm, 42.89±0.31; Acres), respectively. A basal diet typical commercial...

Methods A three-hundred twenty 33-week-old Hy-Line Brown hens (Gallus domesticus) were evenly assigned four experimental 2,750, 2,850, 2,950, 3,050 kcal AMEn/kg pens with floors covered deep litter rice hulls. There...

This study investigated the effects of corn resistant starch (RS) on anti-obesity properties, nutrient digestibility, and blood parameters in healthy beagles. Four spayed six castrated beagle dogs were divided into a control group (CON) with diet comprising rice chicken meal treatment (TRT) an increased RS content by heating-cooling meal. All CON TRT groups fed 1.2-fold higher energy than daily recommended requirement for 16 weeks. Throughout period, body weight increased, whereas no change...

2][3][4] According to the Surgeon General's Report, term "second-hand smoke" is considered better capture involuntary nature of exposure. 5In those studies, assessment methods for exposure second-hand smoke were largely divided into a self-reported using questionnaire and an objective biomarker such as cotinine.The latter be more accurate smoke.Previous studies have reported agreement between self-report estimation with regard among pregnant nonsmokers. 6-10Among Rebagliato et al. 6 that...

In this study, we describe a previously undescribed pedunculated serrated polyp of the colon showing typical features sessile adenoma/polyp (SSA/P). All polyps were pedunculated, located in proximal colon, small size, and occurred elderly patients. Histologically, showed SSA/P basal crypts with irregular, asymmetric expression Ki-67. BRAF-V600E mutation. The cells did not show obvious cytologic dysplasia, prominent serration, or diffuse cytoplasmic eosinophilia any occurrence so-called...

Digestibility of pet food can affect the health dog, especially aged animals. To maintain dogs in an overall good status it is necessary to provide nutritionally balanced food. For example, digestibility was known be decreased along aging. In addition, losing teethes often event that could induce a problem eat large size dry Nonetheless, few detailed information available on most suited feeding for dogs. As part nutritional study dogs, this study, we tested whether type impacts adult versus...

Looking for alternative omega-3 sources in broiler nutrition, microalgae began to get attention. We suspected that schizochytrium might play a similar role as other have been used before.20 g/kg powder (SP), salmon oil (SO), and flaxseed (FO) each of the three treatment groups were supplemented basal diet (CON), productive performance, carcass traits, thigh meat quality broilers evaluated.There was significantly higher weight gain SP compared groups, but no difference found feed intake...
