Lipopolysaccharide (LPS) induces rapid necrosis of intradermal fibrosarcomas in mice. The mechanism(s) by which LPS produces tumor necrosis has been investigated using histocompatible LPS-sensitive (C3H/HeN) and LPS-resistant (C3H/HeJ) mouse strains. C3H/HeN- or C3H/HeJ-derived fibrosarcomas were necrotized by LPS when they were grafted onto C3H/HeN mice but were not affected when growing on C3...

Melanocortin-3 receptor (MC3R) plays an important role in the central control of energy homeostasis, and several functional polymorphisms of this gene have been detected. We have studied MC3R as a candidate gene responsible for variation in economically important traits in chicken. To determine the association between MC3R polymorphism and phenotypic variation, a total of 190 individuals from b...

In 2016 a total number of 297 samples were tested in the frame Salmonella control programmes Bulgaria including official (n = 101) and by business operators 196). The originated from 3 categories hen flocks: 48 pcs. breeding flocks, 175 laying hens 74 broilers. belonged to different groups: I – fresh feces, boot swabs fabric socks 281), II dust 10), III egg shells 6). laboratory tests performed...

the effect of yeast culture (saccharomyces cerevisiae) supplementation on laying hen diets was tested against flavomycin supplementation during 12 weeks, using 112 brown bovans laying hens, 52 week-old, divided into 7 equal groups fed on a basal diet containing 18.8% crude protein and 2810 kcal/kg me (metabolizable energy) feed. three groups were supplemented with 3 different levels of commerci...

Values-based indicators of risks to Indigenous health have the potential to improve the accuracy and quality of a wide range of decisions affecting Native lands and cultures. Current health impact assessment approaches often omit important health priorities rooted in the history, social structures, and cultural context of Indigenous communities. Insights and methods from the decision sciences c...

A cross-sectional study was conducted to determine the influence of farmers’ trait preferences and breeding practices on local chicken genetic resource conservation in Igunga District, Tabora Region Tanzania. The used proportionate random sampling obtain 384 respondents ten villages within two wards. Data were collected through a household survey, key informant interviews (n=5), focus group dis...

the study was conducted to evaluate the effects of different dietary oil sources supplementation on laying hens’ performance and fatty acids profile of egg yolks. seventy-two 23-week-old laying hens (tetra-sl) divided into six experimental diets (four replicates and three birds per replication) in a completely randomized design for nine weeks. experimental diets were included: 1) control (no oi...

This study assessed the provision of education and support to parents of children on home enteral nutrition (HEN), current dietetic support available and perceived challenges facing parents and carers. From the 39 responses (13%), 29 (83%, n = 35) parents suggested services for HEN need improvement. 29 (74%, n = 39) parents wanted more structured follow up and 22 (56%) would like one person to ...
