Intensive Development

Significance of stocking density in broiler production i.e. production performance, vitality and health condition of chickens, was established at the beginning of development of industrial poultry production. However, considering intensive development of selection work and creation of more productive genotypes which, at the same time, were more demanding in regard to rearing conditions, the current importance of this research is not diminished. In favour of this statement is also the complexity of the effect of stocking density which is direct, indirect, and interacted with other factors of rearing, which eventually reflects on all aspects of broiler production: economical efficiency, quality of products and broiler welfare aspects. In the paper a review of research results is presented with general objective to define optimal stocking density in broiler production based on comparison of effects on production performances, parameters of carcass quality and indicators of broiler welfare.

Nh3 Emission

A partially (50%) perforated flooring system showed positive effects on health- and behavior-based welfare indicators without affecting production performance. Ammonia (NH3) is the most common air pollutant in poultry production, with effects on animal welfare and the environment. The objectives of animal welfare and environmental protection are often incompatible. Therefore, this study addresses the question of how a partially perforated flooring system affects NH3 emissions. According to German regulations, three fattening periods were carried out with 500 Ross 308 broilers per barn (final stocking density: 39 kg m−2). The experimental barn was equipped with an elevated perforated area in the supply section, accessible by perforated ramps. The remaining area in the experimental barn and the control barn were equipped with wood shavings (600 g m−2). Besides the different floor types, management was identical. Air temperature (Temp), relative air humidity (RH), NH3 concentration, and ventilation rate (VR) were measured continuously. Furthermore, dry matter (DM) content, pH, and litter quality were assessed. Towards the end of the fattening periods, the NH3 emission rate (ER) of the partially perforated flooring system was higher compared with that of the littered control barn (all p < 0.001). This effect is mainly caused by the higher NH3 concentrations, which are promoted by the lack of compaction underneath the elevated perforated area and the increase in pH value under aerobic conditions. Nevertheless, the partially perforated flooring system offers different approaches for NH3 reduction that were previously not feasible, potentially contributing equally to animal welfare and environmental protection.

The Impact

The source of water, the content and quality is very important used in every stage of poultry production. The birds must have continuous access and supply of quality water without any antibiotic and bacteriological residues. Sensory, physiochemical properties and chemical composition must be taken into consideration while assessing water quality. The quality of water used in the production of conventional or organic poultry has impacts on the poultry health, quality of products and human health. The impact of water quality is higher on the functionality of water in live organism and the consumption amount varies depending on many factors. A source of water which is used in organic production is also important with their characteristics. Different water sources may be used for animal consumption, such as springs, shallow wells, deep and artesian wells, lakes and creeks. Organic farms should regularly submit water samples to a laboratory for testing of water quality against the possibility of contamination of water sources. Water contaminants could create equipment problems and restrict the amount of water available for consumption therefore affects the quality of products. There are many aspects to the broad problems of water quality and different physical and chemical applications used to ensure sustainability of water quality for human and animal use. In this review, it will be focused on the quality of the water to be used in the organic poultry production and quality enhancing physical and chemical applications.

The Impact

Stocking density is considered one of the most important factors for the welfare of broilers. This paper is continuation of the study in order to obtain full evaluation of the impact of different broiler stocking densities on production performance, condition of the broiler legs and body feathering, as welfare indicators but also indicators of the productivity and quality of produced chickens. The effect of three stocking densities (20, 15 and 10 birds/m2) was investigated in 4 repetitions on broilers of genotype Hubbard at the age of 3 and 6 weeks. At the age of 6 weeks stocking density of 20 birds/m2 resulted in significantly lower growth of broilers, higher mortality and higher incidence of leg lesions and problems with body feathering, compared to stocking densities of 15 and 10 birds/m2.

Poultry egg and meat are the two cheapest sources of animal proteins for non-vegetarians across the globe. The improvement of poultry production needs to be efficiently carried out for which various tools are to be adopted. Simple breeding theory inculcates mating among the superiors, which is being practiced since long before. Poultry improvement has gained momentum to augment the performance of birds not only in terms of production but also sustainability. Chickens are mainly classified as eggtype chicken and meat-types chickens. Along with the major production traits, other functional traits such as feed efficiency and nutrient quality of poultry produce are being given due emphasis to achieve the major target. Many conventional selection and breeding approaches have been adopted by the animal breeders to improve these traits. Due to the inherent nature of population and selection criteria, the rate of genetic progress became relatively slow and ultimately, the variability of pure line populations has been gradually shrunken. The nutritional approach maximizes the net profit of the poultry rearing by providing suitable niche to express the desired economic traits in optimum capacity. Recently, genomic selection and biotechnological approaches are showing high potential to enhance the productivity of birds at faster rate.

Environmental health is referring to the health of people in relation to environmental quality. Due to rapid urbanisation, more people are living in urban neighbourhoods. Urban planning and design aspects including the neighbourhood environment are potentially affecting the human healthy lifestyle and health condition. Thus, the relationship between Malaysian neighbourhood environmental aspects and human health has become the concern of this research. One of the neighbourhood units in Shah Alam city had been chosen as the study area for this purpose. Questionnaire survey had been carried out to examine the health condition and physical activeness of residents. Besides, the perception of residents on the quality of neighbourhood environmental aspects also had been collected in the questionnaire survey. The health condition of residents was measured by non-communicable diseases (NCD) and the physical activeness was measured in duration as well as the frequency of physical exercise activities. The study found that the quality of neighbourhood environmental aspects significantly increased the physical activeness of respondents. The physical activeness was positively associated with human health as measured in NCD (heart diseases and high blood pressure, HBP). It shows that neighbourhood environmental (physical and social) aspects are potentially affecting the healthy life of people living in the neighbourhood.Keywords: Healthy life, Neighbourhood environment, Non-communicable diseases (NCD), Physical activeness, Quality.
