Feeding Regimen

To evaluate the effect of a production system and feeding regimen on meat quality attributes of Naked Neck chickens, a total of 150 cockerels at 18 weeks old (1625 ± 70 g) were collected from 10 treatment groups with five replicates of three birds. The factorial arrangement of treatments consisted of two production systems (intensive and free-range) and five nutritional regimens, namely 100% commercial feed; 75% commercial feed plus 25% kitchen waste; 50% commercial feed plus 50% kitchen waste; 25% commercial feed plus 75% kitchen waste; and 100% kitchen waste. Carcass traits, meat quality, and meat organoleptic were found to differ significantly among production systems, feeding regimens, and their interaction. Higher liver weight was observed in birds reared under an intensive system. Higher gizzard weight was noted in birds fed with 100% kitchen waste, whereas lower gizzard weight was observed in birds fed the commercial diet. The meat from cockerels fed with 75% kitchen waste was most yellow, whereas the meat from the birds fed with 100% kitchen waste was least yellow. At two hours after slaughter, pH of the meat was highest in birds fed 50% kitchen waste and lowest in birds fed 100% kitchen waste. The interaction of production system and feeding regimen was significant for overall acceptability score. In conclusion, Naked Neck chickens performed equally well under intensive and free-range systems, irrespective of the level of kitchen waste that they were fed.

The effect of production systems on the sensory quality characteristics of Dorper lambs was investigated. Sixty lambs (ewes, rams, castrates) were allocated into two production groups (feedlot or free-range) at weaning with equal numbers of each sex represented in each group. The lambs were fed for five (slaughter group 1) or six (slaughter group 2) weeks. Feedlot lambs were fed a commercial pelleted diet while free-range lambs utilized natural shrub pastures. Samples of the Longissimus thoracis muscle were used for sensory evaluation. Feedlot lambs produced meat that was juicier and more tender than meat from free-range lambs. Initial juiciness was also higher in the meat from the feedlot lambs. No aroma or flavour differences were observed. The meat from the free-range ram lambs (slaughter group 1) was the least tender, whereas the lamb flavour was also compromised in the free-range ram lambs. Free-range meat may not necessarily be distinguished from feedlot meat as far as aroma and flavour are concerned.

ABSTRACT The current study investigated the effect of environmental stressors (i.e., weather changes) on Salmonella shedding in free-range production systems and the correlations with behavioral and physiological measures (i.e., fecal glucocorticoid metabolites). This involved longitudinal and point-in-time surveys of Salmonella shedding and environmental contamination on four commercial free-range layer farms. The shedding of Salmonella was variable across free-range farms and in different seasons. There was no significant effect of season on the Salmonella prevalence during this investigation. In this study, the combined Salmonella most probable number (MPN) counts in environmental (including feces, egg belt, dust, nest box, and ramp) samples were highest in samples collected during the summer season (4th sampling, performed in February). The predominant serovars isolated during this study were Salmonella enterica serovar Mbandaka and Salmonella enterica serovar Typhimurium phage types 135 and 135a. These two phage types were involved in several egg product-related Salmonella outbreaks in humans. Multilocus variable-number tandem-repeat analysis (MLVA) results indicated that MLVA types detected from human food poisoning cases exhibited MLVA patterns similar to the strains isolated during this study. All Salmonella isolates (n = 209) were tested for 15 different genes involved in adhesion, invasion, and survival of Salmonella spp. We also observed variations for sopA, ironA, and misL. There were no positive correlations between fecal corticosterone metabolite (FCM) and Salmonella prevalence and/or shedding in feces. Also, there were no positive correlations between Salmonella prevalence and Salmonella count (log MPN) and any of the other welfare parameters. IMPORTANCE In this study, the welfare of laying hens and Salmonella shedding were compared over a prolonged period of time in field conditions. This study investigated the long-term shedding of Salmonella serovars in a free-range egg production system. Given that there is increasing demand for free-range eggs, it is essential to understand the risks associated with such a production system.

AbstractThe objective of the study was to determine the effect of breed (A) and free-range production system (B) on quality of meat from hens of two breeds, Greenleg Partridge (Z-11) and Rhode Island Red (R-11), which are under the biodiversity conservation programme in Poland. Subjects were 120 hens of each breed, which were assigned to two treatment groups differing in the housing system: 60 layers were kept on litter without outdoor access (C) and 60 layers were raised on litter with access to free range (FR). At 56 weeks of age, 8 hens were randomly chosen from each group, slaughtered, and subjected to slaughter analysis. It was found from the study that carcasses from 56-week-old multi-purpose hens are characterized by poor muscle development and considerable fat content. After the first year of egg production, the meat of hens was characterized by low tenderness, high water holding capacity, and a fatty acid profile that was desirable from the viewpoint of human nutrition. In the meat of hens that completed their first year of egg production, the profile of fatty acids was beneficial from the standpoint of human nutrition. The free-range production system reduced carcass fatness, enhanced carcass and meat yellowness, and increased the proportion of polyunsaturated fatty acids (both n-6 and n-3) in breast and leg muscles while causing no significant changes in the content of saturated fatty acids. The meat of the native Z-11 breed was found to contain less saturated and more unsaturated fatty acids compared to the meat of R-11 hens. There was no statistically significant effect of the production system on the sensory evaluation of cooked meat and broth.

AbstractIn 2008, California passed Proposition 2, specifying confinement space for certain farm animals. Proposition 2 went into full effect January 2015 and has significant implications for egg production in California and possibly even interstate commerce. We examined the influence of promotional videos aired during the campaign on consumers’ willingness-to-pay for eggs produced in a more open production system (i.e., cage-free, free range) and corresponding neurofunctional activations during decisions. Forty-six participants (24 females), aged 18–55 years (

Increasing poultry product consumption trends have attracted researchers and development practitioners to look for interventions that transform the low-input low-output-based village chicken production to a high yielding production system. However, due to the intricate nature of the production system, there is a dearth of evidence that helps design comprehensive interventions at the smallholder level. Using national-level representative data collected from 3555 village chicken producers in Ethiopia, Nigeria, and Tanzania, this study examines the technical efficiency of village chicken production and investigates the main factors that explain the level of inefficiency. We applied a stochastic frontier analysis to simultaneously quantify the level of technical efficiency and identify factors associated with heterogeneity in inefficiency. We found that the level of technical efficiency is extremely low in the three countries, suggesting enormous opportunities to enhance productivity using available resources. The heterogeneity in technical efficiency is strongly associated with producers’ experience in breed improvements and flock management, limited technical knowledge and skills, limited access to institutions and markets, smaller flock size, gender disparities, and household livelihood orientation. We argue the need to adopt an integrated approach to enhance village producers’ productivity and transform the traditional subsistence-based production system into a commercially oriented semi-intensive production system.

AbstractA total of 211 pheasants (Phasianus colchicus) were reared using two different production systems (free range and intensive) to determine the effect of production system and slaughter age on growth performance and carcass traits. Birds were slaughtered at 14, 16, and 18 weeks of age. Production system did not significantly affect body weight until 18 weeks; at this age, pheasants reared in free range exhibited a higher average weight (1149 g vs. 1012 g). Total feed consumption and feed conversion ratios did not differ among production systems. The most in-demand portions of the carcass (breast and leg) were not affected by differences in production system. The leg and breast proportions which were the most edible parts of the carcass were around 26% and 35%, respectively, in both free-range and intensive systems.
