The egg production sector is in a transitional period with regard to the permitted housing systems, i.e. rearing conventional cages under certain conditions complete ban of any form cage system. changes were caused by concern for layer wellfare but expected effects on productivity as well. aim research was determine floor space allowance and non-cage systems feather score laying hens three ages...

An experiment was conducted to study the effect of Epinephrine (EP) and bromocriptine (BR) on productive traits of laying hens. Thirty White Leghorn hens, 50 weeks old, were divided into three equal treatments (with 10 hens for each treatment): control, physiological serum (0.5 mL/hen/week), EP (0.5 mL/hen/week) and BR (100 g/kg of body weight (BW); w/v in absolute alcohol). Hens were injected ...

The difference in susceptibility to urinary tract infection between C3H/HeJ and C3H/HeN mice was tested for with gram-negative strains differing in lipopolysaccharide composition. Recently, impaired clearance of Escherichia coli from the kidney of C3H/HeJ compared to C3H/HeN mice was shown to be correlated with the LPS low responsiveness. In this study, a difference in clearance from the kidney...

BACKGROUND Home enteral nutrition (HEN) has always been recognized as a life-saving procedure, but with the ongoing economic crisis influencing health care, its cost-effectiveness has been questioned recently. OBJECTIVE The unique reimbursement situation in Poland enabled the otherwise ethically unacceptable, hence unavailable, comparison of the period of no-feeding and long-term feeding and ...

Population introduction is an important tool for ecosystem restoration. However, before introductions should be conducted, it is important to evaluate the genetic, phenotypic and ecological suitability of possible replacement populations. Careful genetic analysis is particularly important if it is suspected that the extirpated population was unique or genetically divergent. On the island of Mar...

Ahead of heat exchanger network (HEN) design, setting an optimal pinch temperature difference for analysis depends vitally on the capital cost target. Conventional methods based spaghetti (SPA) structure ignoring matching optimization might result in calculated targets large deviations. This work evolved SPA via four stages by shifting energy towards low-cost matching. The fourth from (ESPA-IV ...

An experiment was carried out to investigate the effects of powdered vegetable dip sauces to improve the tenderness of spent-hen breast meat. Our overall purpose was to find lower-priced materials for the tenderization of spent-hen breast meat. The spent-hen breast meat was dipped into vegetable powder for 24 h at 4°C, and then the samples were analyzed. In the results for vegetable-powder trea...

INTRODUCTION Home enteral nutrition (HEN) is indicated in patients with a functional gastrointestinal tract but who are unable to meet their nutritional requirements with normally consumed foodstuffs. HEN allows patients to remain in their social and family environment, thus reducing complications and costs associated with hospital admission, while increasing health-related quality of life (HRQ...

The modal DNA content of normal marrow megakaryocytes from species so far examined usually has been reported to be 16N. In this report we describe an exception in the C3H mouse whose megakaryocytes have a modal DNA content of 32N. Female C3H/HEN mice had an average DNA content distribution of 14% 8N, 37% 16N, 43% 32N, and 6% 64N. Male C3H/HEN mice had somewhat higher proportions of 32N and 64N ...

A completely randomized design experiment was conducted to evaluate the effect of feeding different levels (0, 2.5, 5.0, 10.0, 20.0%) of guar meal (GM) in laying hen diets over a 8-wk trial period. A total of 180 Hisex laying hens (25wk old) of similar body weight were randomly distributed among 5 treatments with 6 replicates with 6 hens each. Body weight, body weight gain, egg produced per hen...
