Backyard poultry production are considered as sources of meat and egg production. However, Parasites are among the main pathogenic agents, threatening the health of poultry and poultry products. The current study was conducted to investigate the prevalence of ectoparasite of poultry managed under backyard system started from November 2019 to April 2020 in Bishoftu town, surroundings of four kebeles; Babogaya, Danbi, 01kebele and 05 kebele in Oromia region South east of Finfinnee. 384 chickens of different age groups, both sexes and breeds were examined. Overall, 228/384 (59.4%) of chickens were infested with species of ectoparasites that mainly grouped into lice 141(36.7%), flea 79 (20.6%), and mite 8(2.1%). The prevalence of ectoparasite infection was 56(14.6%), 51(13.3%), 58(15.1%) and 63(16.4)% in Bishoftu town, Babogaya, Danbi, 01kebele and 05 kebele respectively, the difference in the prevalence of the parasites among difference kebeles were not statistically significant (P>0.05). The prevalence of ectoparasites infestation was higher in male 128(33.33%) chickens than females 100(26.04%) and higher in adult 150 (39.1%) than young chicken 78 (20.3%), high in local breeds 129(33.6%) than exotic breed 99 (25.8%). Seven species were identified with their attachments site, namely; menacanthus stremineus(13.3%) was found on skin, menopon gallinae(12.5%) was found on skin, thigh, feather and breast, goniodes gigas(5.5%) was found on skin and body feather, gonicotes gallinae (2.9%) was found on feather, lipeurus caponus(2.6%) was found on wing, skin, tail feather and a single species of flea(Echidnophaga gallinacae) 20.6% was found on eye, comb and wattle. while a single species of mite (ornithonyssus sylviarum) 2.1% was found on base of feather particularly, the vent area. In conclusion, infestation of chicken with ectoparasites was important constraint in poultry production sector. Associated with lack of attention with respect to hygienic system, treatment and control practices. Based on the results it could be suggested that, good management, biosecurity and the education of farmers could be a vital measure to keep free from ectoparasites and improve the productivity of the chicken.

Poultry farming is integral part of agriculture in Nepal. The objective of this research was to analyze the prevailing production constraints, characterization of poultry farming and its economic analysis using questionnaire-based survey and on-site investigation. 180 farms were selected from 3 major districts. Garrett’s ranking technique was used to analyze the constraints.  Highly significant difference (P<0.01) in size of poultry farm was found. We found significant difference in feeding, housing and drinking system for the chicken. Un-organized chicken marketing channel was observed in the study area.   High chicks’ mortality, wastage of feed, insecure vaccination and frequent drop in egg production were characteristic of laying hens. Newcastle disease and Chronic Respiratory Disease were acknowledged as the biggest constraint of chicken production. Government and concerned agencies need to take active part for the extension service to strengthen the health of chicken and organized marketing channel is essential for selling of poultry products  which can improve the profit to the farmers.Int.

Background. Knowledge regarding the relationship between writing kinetics and the difference among writing tasks is limited. Purpose. This study examined the differences in handwriting performance when doing tasks with different levels of challenge from both temporal and kinetic perspectives among children in four different age groups. Method. The cross-sectional design introduced a force-acquisition pen to detect differences of pen grip and writing kinetics among 170 school-age children doing writing tasks at different difficulty levels. Data were obtained on the force information of the digits and pen tip and the kinetic parameters to examine the coordination-and-control mechanism between the digits and pen. Statistical analyzes were carried out to indicate the differences in writing performance among groups and tasks. Findings. Statistical differences in the pen-grip forces, force fluctuation, and force ratio between grip and pen-tip forces were found when performing different writing tasks and among different age groups. Implications. The study provides an alternative method to explore how writing performance among school-age children can vary according to the difficulty of the writing tasks.

Fertile egg production and incubation and production of broiler meat are both an art and a science. Man has taken full control of incubating fertile eggs by artificial means to supply the increasing world demand for poultry meat. It is estimated that worldwide more than 30 billion broiler fertile eggs are incubated annually. If eggs were still incubated naturally and broilers raised in small backyard farms, the poultry industry would not have been able to grow and prosper as it has and supply the world demand for poultry products. This document is VM133, one of a series of the Veterinary Medicine-Large Animal Clinical Sciences Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

AbstractStressors experienced by layer breeders during egg production can lead to changes in the egg hormone content, potentially impacting their offspring, the commercial layers. Genetic differences might also affect the offspring’s susceptibility to maternal experiences. In this study, we tested if maternal stress affects measures of stress and fear in five strains of layer breeders: commercial brown 1 & 2, commercial white 1 & 2 and a pure line White Leghorn. Each strain was equally separated into two groups: “Maternal Stress” (MS), where hens were subjected to a series of 8 consecutive days of acute psychological stressors, and “Control,” which received routine husbandry. Additional eggs from Control were injected either with corticosterone diluted in a vehicle solution (“CORT”) or just “Vehicle.” Stress- and fear-responses of the offspring were measured in a plasma corticosterone test and a combined human approach and novel object test. Both MS and CORT treatments failed to affect the measured endpoints in the offspring, but significant strain differences were found. The offspring of the white strains showed a higher physiological response compared to brown strains, but the White 2 offspring was consistently the least fearful strain in the behaviour tests. Our study found that the acute psychological stressors experienced by layer breeders did not affect the parameters tested in their offspring and that corticosterone does not seem to be the primary mediator of maternal stress in laying hens. This is highly important, as in poultry production, layer breeders are often subjected to short-term stressors. In addition, we successfully dissociated the physiological and behavioural parameters of stress response in laying hens, showing that increased concentrations of plasma corticosterone in response to stress is not directly associated with high levels of fear.

Introduction: Salmonellosis is one of the major foodborne diseases known to be closely related to the consumption of contaminated eggs, infected poultry, and poultry products. Control and survey of the poultry chain are the key elements and the most critical steps in the prevention of human transmission of Salmonella. Methodology: This study was carried out in East Algeria on 150 eggs meant for consumption collected from mini-markets and immediately tested for Salmonella using standard methods (ISO AFNOR 6579 modified in 2002). Briefly, the shell surfaces were carefully wiped using sterile appropriated tissues while the white and yellow yolks were separated. All 10 samples were pooled together and a total of 45 samples were carefully analyzed. Results: A contamination rate of 4.4% was found, and two strains of Salmonella bradford were isolated from white and yellow yolks. The results showed that XLT4 was the best medium for Salmonella isolation from yolks. Screening for other Salmonella in parental chickens using an enzyme-linked immunosorbent assay (ELISA) test revealed seropositive cases of Salmonella enteritidis at the top of the poultry production pyramid. Conclusions: Occurrence of Salmonella in yolks and seropositive results for S. in parental chickens is a serious and potential danger to public health. Radical and preventive measures must be taken at the critical points to control and to avoid human transmission. These measures must be installed at all levels of egg production through the application of appropriate and strict regulations, and use of good hygienic practices in transport, storage, and food preparation.

AbstractEighty piglets aged 14, 28, 35 and 56 days — weaned at day 28 — were subjected to this investigation. Each age-group consisted of five animals which were fed an Enterococcus faecium NCIMB 10415 (Cylactin®) and Bacillus cereus var. toyoi (Toyocerin®) based diet. Five animals served as controls. Tissue samples were collected immediately after sacrifice at 8.30 h a.m. from duodenum, jejunum, ileum, cecum and colon to examine intestinal morphology and histochemistry. The results showed that with respect to villus height and crypt depth supplementation of probiotics in piglets feed seemed to influence the morphology and enlargement factor not at all or only to a certain extent. With respect to the number of goblet cells, the difference between probiotic fed animals and control animals was generally extremely low. The shape of the villi of the small intestinal segments greatly varied in all age groups of control and probiotic fed animals. However, this morphological variety does not depend on the mode of feeding.

Summary: Our meta-analysis focused on the relationship between homocysteine (Hcy) level and the incidence of aneurysms and looked at the relationship between smoking, hypertension and aneurysms. A systematic literature search of Pubmed, Web of Science, and Embase databases (up to March 31, 2020) resulted in the identification of 19 studies, including 2,629 aneurysm patients and 6,497 healthy participants. Combined analysis of the included studies showed that number of smoking, hypertension and hyperhomocysteinemia (HHcy) in aneurysm patients was higher than that in the control groups, and the total plasma Hcy level in aneurysm patients was also higher. These findings suggest that smoking, hypertension and HHcy may be risk factors for the development and progression of aneurysms. Although the heterogeneity of meta-analysis was significant, it was found that the heterogeneity might come from the difference between race and disease species through subgroup analysis. Large-scale randomized controlled studies of single species and single disease species are needed in the future to supplement the accuracy of the results.

Eye Movements During Reading

Abstract. We report the results of a meta-analysis of 22 experiments comparing the eye movement data obtained from young ( Mage = 21 years) and old ( Mage = 73 years) readers. The data included six eye movement measures (mean gaze duration, mean fixation duration, total sentence reading time, mean number of fixations, mean number of regressions, and mean length of progressive saccade eye movements). Estimates were obtained of the typified mean difference, d, between the age groups in all six measures. The results showed positive combined effect size estimates in favor of the young adult group (between 0.54 and 3.66 in all measures), although the difference for the mean number of fixations was not significant. Young adults make in a systematic way, shorter gazes, fewer regressions, and shorter saccadic movements during reading than older adults, and they also read faster. The meta-analysis results confirm statistically the most common patterns observed in previous research; therefore, eye movements seem to be a useful tool to measure behavioral changes due to the aging process. Moreover, these results do not allow us to discard either of the two main hypotheses assessed for explaining the observed aging effects, namely neural degenerative problems and the adoption of compensatory strategies.

Abstract The paper attempts to determine an optimum structure of a directional measurement and control network intended for investigating horizontal displacements. For this purpose it uses the notion of entropy as a logarithmical measure of probability of the state of a particular observation system. An optimum number of observations results from the difference of the entropy of the vector of parameters ΔHX̂ (x)corresponding to one extra observation. An increment of entropy interpreted as an increment of the amount of information about the state of the system determines the adoption or rejection of another extra observation to be carried out.
