Laying Performance

A comparative analysis of reproduction parameters and hatchability results of pheasants raised under two different housing systems (cages and aviaries) was performed. In the first system the pheasants were housed in 420 cages, 3780 from the total were females. In the second housing system, 3200 pheasant hens were placed in eight aviaries, where 50 cocks and 400 hens were kept in each. The following parameters were calculated: laying rate, the percentage of hatching, small and cracked eggs, hatchability from set and fertilized eggs, dead embryos up to day 8 of incubation and, finally, dead embryos after day 8 of incubation as well as unhatched, crippled, and weak chicks. The laying rate for the whole period of reproduction in pheasants kept in cages was significantly higher in comparison with aviaries (59.6 vs 27.2%). A higher (P ≤ 0.05) percentage of small and damaged eggs (  = 13.6) was recorded in aviaries. The percentage of dead embryos for eggs derived from aviaries, up to day 8 of incubation, was also significantly higher (–x = 4.7%). There were no significant differences between the housing systems with respect to the remaining features. The results of the investigation made it possible to conclude that pheasants kept in cages were characterized by a higher laying performance with fewer eggs unsuitable for incubation. A lower mortality of embryos during the incubation process was found in eggs derived from pheasants reared in cages. Although there were no significant differences between the analyzed housing systems in terms of hatchability, a higher laying rate for pheasants kept in cages implies that more chicks could be obtained from every female.

Cecal Microbiota

Housing systems are among the most important non-genetic factors affecting hen production performance and intestinal microbes. With increased interest in animal welfare, cage-free laying hen housing systems have become common, providing behavioral freedom and health benefits. The present study aimed to compare the effects of plastic net housing system (NRS) and floor litter housing system (LRS) on the composition and function of the duodenal and cecal microbiota in Shendan chicken, one of the most popular laying hen strains in China. The associations between the differential microbiota abundance and production traits and intestinal morphological parameters were determined. Compared with the LRS, the NRS improved the laying rate (p < 0.05) and increased the villus height (VH) of the duodenum (p < 0.05) and the VH-to-crypt depth ratio (VCR) of the cecum (p < 0.05). Alpha diversity analysis showed that LRS chickens had a significantly higher diversity and richness than NRS chickens. Beta diversity analysis demonstrated differences in the microbiota composition based on housing systems. Within the cecum, Proteobacteria and Kiritimatiellaeota were significantly more abundant in the LRS than in the NRS (p < 0.05), while Bacteroidetes were significantly less abundant in the LRS (p < 0.05). Phascolarctobacterium and Ruminococcaceae_UCG-005 were significantly less abundant in the LRS (p < 0.05) compare to the NRS. Within the duodenum, Lactobacillus was significantly less abundant in the LRS (p < 0.05) than in the NRS, while Pseudomonas was significantly more abundant in the LRS (p < 0.05). Cecal Phascolarctobacterium and Ruminococcaceae_UCG-005 were significantly positively correlated with eggshell strength (R = 0.608, p < 0.01) and egg weight (R = 0.526, p < 0.05), respectively. Duodenal Lactobacillus was significantly positively correlated with VH and VCR (R = 0.548 and 0.565, p < 0.05), while Pseudomonas was significantly negatively correlated with the Haugh unit (R = −0.550, p < 0.05). In conclusion, there are differences in the cecal and duodenal microbiota compositions of Shendan laying hens reared in different non-cage housing systems, and the NRS was superior to the LRS in improving the laying performance and intestinal morphology and microecological environment.

The objective of this study was to compare the performance, egg quality, and microbial contamination of egg shells from hens maintained in different housing systems, such as conventional and enriched cages, litter, and aviaries. The housing system significantly (P < 0.001) influenced the performance characteristics. The highest egg production, lowest daily feed consumption, and feed conversion ratio were measured in conventional cages compared to litter and aviaries. Higher egg shell and albumen qualities were observed in conventional cages, whereas hens housed in enriched cages and aviaries laid eggs with a higher yolk index (P < 0.001). The housing system significantly (P < 0.001) influenced the total count of bacteria on the egg surface and the microbial contamination of Enterococcus and Escherichia coli. The lowest values for the total count of bacterial contamination (P < 0.001) were found in eggs from conventional cages (4.05 log colony-forming units (CFU)/egg) and enriched cages (3.98 log CFU/egg). Eggs from aviaries had 5.49 log CFU per egg, and the highest level of contamination was observed in eggs that were laid on litter (6.24 log CFU/egg). The level of the microbial contamination of egg shells from litter and aviaries was by 2 log CFU higher than in eggs from cages. It could be concluded, from the viewpoint of egg safety, a more suitable substitute for conventional cages are enriched cages and aviaries than litter.

Ehrlichia canis is a tick-borne rickettsia. It can cause canine monocytic ehrlichiosis (CME). Infected dogs are often reported to have changes in their blood values, such as anemia, thrombocytopenia, increased liver enzymes, and increased kidney function values. This study aimed to collect data that may be related to infected dogs, including age, gender, breed, weight, close-open housing system, the use of ectoparasiticides products. The sample comprised 57 infected dogs. Collecting hematology and serum biochemistry changes in comparison with the reference values of dogs detected with Ehrlichia canis from 2017-2019, Thonburi District, Bangkok, Thailand was also carried out. In summary, dogs infected with Ehrlichia canis mostly included mixed-breed dogs aged between 1 and 10 years. There were no differences in body weight or housing systems. Dogs that had never used ectoparasiticide products or used them intermittently were infected more often (by 7.14 times) than protected. Clinical hematology and serum biochemistry found anemia, thrombocytopenia, and increased liver enzymes.

The performance of male and female quails reared separately in cages and on deep litter was investigated. One hundred and eighty 3-week old quails managed for five weeks. There were three replicates per treatment with stocking densities of 120cm2/bird in cage and 180cm2/bird on deep litter and sex as a block factor. Data on weekly body weight, weight change, daily feed and water intakes, feed: gain, carcass yield and costs of production were analysed. Daily water consumed by quails between the housing systems (62.76±11.21mL/d on deep litter vs. 66.96±12.18mL/d in cage system, p>0.05) were same. However, quails housed on deep litter consumed more feed from 43-56 days of age (25.34±1.77g/d vs. 22.99±1.55g/d). Quails reared on deep litter also grew faster during the first week of that period (3.33±1.70g/d vs. 0.69±0.87g/d). However, gain in body weight was noticed from day 22 to day 49 but a sudden decline thereafter for all quails regardless of sex and housing system. Carcass yield was not affected by housing system but values for thighs, empty gizzard and liver of quails kept on deep litter were higher (respectively 12.95±0.86% vs. 11.99±0.83%, 2.12±0.18% vs. 1.84±0.20%, 2.11±0.59% vs. 1.88±0.43%; p<0.05). Production costs were the same (p>0.05) whether on deep litter (3414.30±172.95CFA/kg) or in cages (3283.43±77.72CFA/kg). However, the production cost per kilogram of carcass of male quails was lower compared to females (3205.88±138.95CFA/kg vs. 3484.35±131.57CFA/kg, respectively) regardless of the housing system. Sex and age of quails affect performance and not the type of housing system.

Recent Developments

This paper provides an overview of recent developments in rearing conditions, health and welfare issues of dairy cows. The last approximately 30 years has witnessed worldwide increasing scientific research, consumer activity, and political response towards housing condition, health and welfare issues of dairy cattle. All buildings and housing systems for dairy cattle should be designed, constructed, maintained and managed to assist in the achievement of the Five Freedoms: freedom from hunger and thirst, freedom from discomfort, freedom from pain, injury and disease, freedom to express normal behavior and freedom from fear and distress. Whether dairy cows are housed in cubicles, straw yards or cow sheds, in order to maximize their performance and to ensure satisfactory standards of welfare, the accommodation must provide the most basic behavioral and physiological needs. As an absolute minimum, the housing must provide a comfortable, clean, well drained and dry lying area together with shelter from adverse weather. Also, it must allow the cow to move freely around without risk of injury and certain diseases. If the housing system does not provide for these basic needs, then not only will health, welfare and production of dairy cattle be compromised, but it is likely that failure to comply with the welfare codes and the law relating to animal welfare will occur.

Abstract The present study investigated the effect of the type of alternative housing system, and genotype and age of laying hens on physical traits of egg shell and contents. It was demonstrated that alternative housing system type influenced egg weight and shape, and eggshell color and yolk color intensity. Eggs from free-range system were heavier and were characterized by more intense yolk color. No effect of alternative housing system type on albumen height, value of Haugh units (HU value) and presence of meat and blood spots was noted. Hen genotype had a significant effect on egg weight and eggshell color intensity in each of the alternative housing systems tested in this study. Hy-line Brown hens laid heavier eggs than hens of native breeds. Genotype was also observed to affect egg content traits (albumen height, HU values and presence of meat and blood spots). Independently of the type of alternative housing system, most blood and meat spots were noted in eggs of hens laying brown-shelled eggs, i.e. R-11 and Hy-line Brown layers. Laying hen age significantly impacted on egg weight, yolk percentage, eggshell traits (color intensity, weight, thickness and strength) and egg content traits (HU value, yolk weight and color intensity, presence of meat and blood spots). Older hens laid heavier eggs with a greater yolk percentage but with thinner eggshell.

This chapter outlines how Ireland is an interesting case through which to understand housing, because of its particular history. It shows that housing crises are not new, nor are they universal, either within countries or across different countries. It explores different philosophies of housing, from Keynesianism to neoliberalism. It details Ireland’s housing history, from early state intervention in favour of tenant farmers, and responses to the housing crisis of the early years of the Irish free State through building public council housing. It details local authority housing expansion through the 20th Century, producing high-quality homes and neighbourhoods. It also details the neoliberal housing shift internationally, as a dramatic shift took place in the economic order in the late 1970s and the 1980s. It then introduces the concepts of financialisation and marketisation in housing, and explains ho w neoliberalism unfolded in the Irish housing system. It then details the Irish housing boom and bust of the 2000s. It ends with an overview of cost rental housing: unitary and dualist housing systems, to understand the Irish housing system.

The objective of the present study was to compare the eggshell characteristics and cuticle deposition of Lohmann Brown, Hy-Line Silver Brown, and Isa Brown layers kept in two different housing systems. The three laying hen genotypes were housed in enriched cages (100 hens, 750 cm<sup>2</sup>/hen, 10 hens/cage) and in littered pens (100 hens, 9 hens/m<sup>2</sup>, 10 hens/pen). The experiment was carried out in weeks 40–56 of hens age. Non-significant interactions of genotype and housing system for eggshell quality parameters and cuticle deposition were detected in this study. Egg weight was significantly affected by genotype (P ≤ 0.001) and housing system (P ≤ 0.043). The heaviest eggs were laid by Lohmann Brown, while the lightest eggs were produced by Hy-Line Silver Brown. Eggshell strength was not affected by genotype and housing system, however, genotype had a significant effect on eggshell thickness (P ≤ 0.033). Isa Brown eggs had thicker eggshells compared to Lohmann Brown and Hy-Line Silver Brown. However, a non-significant effect of housing system on eggshell thickness was observed. Eggshell percentage was significantly affected by both genotype and housing system. Genotype of laying hens had a significant effect on cuticle deposition; significantly higher cuticle deposition was observed in Lohmann Brown eggs (P ≤ 0.001). It could be concluded that genotype had a significant effect on eggshell quality parameters and cuticle deposition. However, the housing system effect was less important in these characteristics.

Biting Behaviour

AbstractThe development of adverse behaviour in group–housed growing/ finishing pigs with intact tails was studied in a straw–flow housing system and in a part–slatted system with a commercial enrichment object. Food intake, body weight and behaviour were monitored over the finishing period, with tail biting outbreaks defined as an occasion where three or more pigs within a group had freshly damaged tails and tail biting behaviour was ongoing. Data from the two systems were analysed to identify tail–biting outbreaks and behavioural changes over time. Levels of pig manipulation were higher in the part–slatted system. Over time, pigs in both systems showed reduced interest in the enrichment provided, but not in each other. Despite the presence of the enrichment device, tail biting occurred in all groups in the part–slatted system, but only 1/12 groups in the straw–flow system. The amount of time occupied by manipulation of the enrichment provided was very significantly higher for straw than for the commercial object. Better design of enrichment strategies is therefore needed and should be based on species–relevant requirements.
