Abstract:

Lohmann Brown chickens falls into hybrids with increased productivity of eggs with the genetic potential to produce eggs up to 320 eggs a year per hen and are grown in all climatic conditions. The purpose of this research is to determine how to meet the genetic potential for egg production in chickens hybrid Lohmann Brown, compared with the production results of eggs from this hybrid, derived by applying intensive technology of farm Agripro in Valandovo R. Macedonia in production in year 2014 and 2015. Research is conducted on a sample of 20,500 laying hens in year 2014 and 21,000 laying hens

Abstract:

The aim of this study was to investigate the effect of keel bone damage, housing system, hybrid, and phase of production cycle on the plumage condition of laying hens. The trials were conducted in five industrial farms using different housing systems: enriched cage system, floor system, free range system and aviary system. The hybrids presented were Isa Brown, Hy-Line Brown, Hy-Line Silver Brown and Lohmann Brown. Fifty laying hens per farm were randomly selected for the assessment of keel bone damage and plumage condition. According to their age during assessment of feather cover and keel bon

Abstract:

Severe feather pecking (SFP) is a major animal welfare problem in layers. It results in pain and injuries in the affected animal. It was the aim of this study to gain insight into the actual pecking behavior of laying hens kept on commercial farms with flock sizes common in practice. We observed aggressive pecking and SFP in non-beak-trimmed and beak-trimmed flocks of laying hens and investigated possible influencing factors. The study took place on eight conventional farms in Germany with aviaries, including three farms with a free range and a winter garden, one with a free range and one with

Abstract:

The valorisation of underutilized male layer-type chickens offers a sustainable and ethically aligned opportunity for the poultry industry. This study evaluated the feasibility of male layer-type chicken meat in the production of chicken pâtés and compared the effects of different meat sources—commercial broiler (CP), and 5 (5wP) and 9-week-old (9wP) male layer-type chickens—on product quality during refrigerated storage using the general linear model with the Tukey–Kramer post-hoc test. Pâtés made from 5wP meat exhibited the most favourable technological properties, including the lowest (p &l

Abstract:

The aim of this study was to investigate the effect of additional enrichment materials (EMs; pecking stones and alfalfa bales) on the occurrence of plumage damage, skin injuries, and toe injuries, with an emphasis on the possible differences between commercial hybrid strains of laying hens. During rearing (weeks 1–18, 16 compartments, 4000 pullets) and laying periods (weeks 21–72, 24 compartments, 2808 hens) in a littered housing system, EMs were permanently provided to the study groups (EXP), while control groups (CON) did not receive additional EM.

Abstract:

Fear and exploration are crucial traits determining how animals behave in novel situations, and thus, they influence animal welfare. The aim of this study was the characterization of these behavioral traits among different strains to identify interesting alternatives for future poultry production. Whereas the Novel Object Test (NOT) focuses on fear and exploration of novel objects, the Avoidance Distance Test (ADT) addresses this in the context of humans. Here, a commercial hybrid line, a dual-purpose hybrid and a local adapted strain were tested. For the differences between strains and develo

Abstract:

In commercial egg production, hen productivity declines over time, leading to flock disposal for economic reasons at 72–80 weeks of age. Identifying and removing low-producing hens can enhance economic sustainability by maximising the performance of high-performing hens and conserving feed resources. Additionally, more space per productive hen can improve overall welfare. Current methods for identifying low-producing hens are subjective and challenging, particularly in large operations. Thus, objective culling techniques are needed. This study evaluated hen productivity by examining physiologi

Abstract:

Dual-purpose strains, with hens housed for egg laying and roosters kept for meat production are one alternative to the killing of male day-old chickens. However, dual-purpose hens seem to have additional advantages compared to conventional layers, for instance, a lower tendency to develop behavioral disorders, such as feather pecking and cannibalism. In the present study, three batches of about 1850 conventional layers (Lohmann Brown plus, LB+) and 1850 dual-purpose hens (Lohmann Dual, LD) each, all of them with untrimmed beaks, were observed during production (20–71 (56) weeks of life) in a s

Introduction. The benefits or risks of egg consumption have been a challenge for researchers in identifying the most effective methods for evaluating micronutrients and, implicitly, the nutritional properties of eggs. The purpose of this work was to highlight the comparative nutritional properties of eggs from hens with similar productive yields through innovative methods, such as FT-IR spectra. Methods. This paper aimed to determine the omega 3 fatty acid (O3FA) content in eggs. In this study were used eggs from four different breeds of laying hens: Lohmann Brown, Isa Brown, Australorp and a
