Abstract
Rabbit (RM) has become a valuable source of nutrients since the 1970s, helping to transform the European food industry into the largest RM producer in the world. However, the RM industry is experiencing a critical period of ethical imbalance. This trend, described as feed conversion ratio, impacts the environmental and financial performance of RM farms, which could lead to an increase production of industrial waste. In addition, the loss of corporate ethical responsibility and sustainable development by RM-oriented companies has further exacerbated the situation. Our objective was to summarize current trends in the RM industry and markets, highlighting possible strengths and weaknesses. This review shows current approaches in sustainable techniques in RM production processes, ethical issue, environmental and processing responsibility of RM producers, as well as social responsibilities and ethical practices of slaughterhouses and RM producers, sustainable environmental practices of slaughterhouses, technological aspects and safety of RM and social drivers in RM market. The analysis of reviewed literature revealed the potential strategies for sustainable RM production.

Assessing meat quality and textural properties of broiler chickens: the impact of voltage and frequency in reversible electrical water-bath stunning. Poult Sci 2024; 103:103764. [PMID: 38669823 PMCID: PMC11063635 DOI: 10.1016/j.psj.2024.103764] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Revised: 04/04/2024] [Accepted: 04/09/2024] [Indexed: 04/28/2024] Open
Abstract
The implementation of the head-only electrical stunning procedure in poultry processing has been aimed at enhancing eating, ethical, and religious quality. However, inconsistencies in voltage and frequency standardization, along with variations in previous research outcomes, have led to numerous cases of both under-stunned and over-stunned birds. Thus, this study aimed to comprehensively evaluate the effects of varying voltages and frequencies during electrical water bath stunning on carcass quality, meat attributes, and textural properties in broiler chickens. A cohort of 240 healthy female broilers (Cobb 500, 42-days-old, 2 kg ± 0.1 kg) was meticulously selected from a commercial farm. The birds underwent exposure to different stunning voltages (2.5, 10.5, 30, and 40 V) and frequencies (50 and 300 Hz). Subsequent analyses were conducted on meat samples to assess physicochemical properties, carcass quality, and textural attributes. The findings revealed a higher incidence of petechial hemorrhage (P < 0.05) in birds stunned at 10.5 V compared to other voltage. Notably, no broken bones were recorded in birds subjected to high voltages (30 and 40 V). Low frequency (50 Hz) significantly increased the occurrence of petechial hemorrhage and simultaneously resulted in pectoralis major muscle with decreased redness (a*). Birds subjected to the 10.5 V stunning treatment exhibited a lower cooking loss percentage. Significant interactions between voltage and ageing (V × A) were observed. Birds stunned at 30 V and aged for 7 d displayed highest drip loss compared to a one-day ageing period across different voltage levels. This interaction also impacted pH values, with birds subjected to 10.5 V showing significantly lower (P < 0.05) pH at d 7 of ageing. The meat hardness was influenced by the V × A interaction, wherein birds stunned at 10.5 V exhibited lower hardness after one day of ageing compared to other voltage levels. Red wing tips, lightness (L*), adhesiveness, and resilience were also significantly impacted (P < 0.05) by the interaction between frequency and voltage. A notable 3-way interaction was observed for gumminess and chewiness (F × V × A), where the 2-way interaction between frequency and voltage (F × V) affected both parameters differently at various ageing periods. Additionally, there was a significant interaction (P < 0.05) between frequency and voltage influencing shear strength and yellowness.

Kumar SA, Kim HJ, Jayasena DD, Jo C. On-Farm and Processing Factors Affecting Rabbit Carcass and Meat Quality Attributes. Food Sci Anim Resour 2023; 43:197-219. [PMID: 36909860 PMCID: PMC9998196 DOI: 10.5851/kosfa.2023.e5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 01/20/2023] [Accepted: 01/25/2023] [Indexed: 03/08/2023] Open
Abstract
Rabbit meat has high nutritional and dietetic characteristics, but its consumption rate is comparatively lower than other meat types. The nutritional profile of rabbit meat, by comparison with beef, pork, and poultry, is attributed to relatively higher proportions of n-3 fatty acids and low amounts of intramuscular fat, cholesterol, and sodium, indicating its consumption may provide health benefits to consumers. But, the quality attributes of rabbit meat can be originated from different factors such as genetics, environment, diet, rearing system, pre-, peri-, and post-slaughter conditions, and others. Different rabbit breeds and the anatomical location of muscles may also affect the nutritional profile and physicochemical properties of rabbit meat. However, adequate information about the effect of those two factors on rabbit meat is limited. Therefore, cumulative information on nutritional composition and carcass and meat quality attributes of rabbit meat in terms of different breeds and muscle types and associated factors is more important for the production and processing of rabbits. Moreover, some studies reported that rabbit meat proteins exhibited angiotensin-converting enzyme inhibitory characteristics and antioxidant properties. The aim of this review is to elucidate the determinants of rabbit meat quality of different breeds and its influencing factors. In addition, the proven biological activities of rabbit meat are introduced to ensure consumer satisfaction.

Abstract
Abstract
Increased interest in the production of rabbit meat justifies the need to assess and improve the welfare of these animals not only during the production cycle but also at slaughter. Therefore, the aim of this study was to assess the effects of different stunning methods on the level of blood biochemical parameters (stress indicators), and meat quality of slaughter rabbits. Rabbits of the Hycole line (n = 60) were subjected to the following stunning methods: mechanical with a non-penetrating captive bolt (group I; n = 20), mechanical by hitting a narrow rod on the head (group II; n = 20), and electrical stunning (n = 20). In the stunning groups there were no differences found in the blood level of insulin, cortisol, glucose, total cholesterol, triglycerides, non-esterified fatty acids, and protein content (P>0.05). The stunning method did not affect the pH of rabbit meat (P=0.768), but significantly influenced the L* and b* colour parameters. The muscles of longissimus thoracis et lumborum, from the group of rabbits mechanically stunned by hitting a narrow rod on the head, were the darkest (L * = 58.4), with the lowest yellowness values (b* = 4.04). The meat of electrically stunned rabbits was characterised by higher drip loss (P<0.001), lower plasticity (P=0.043), and higher free water content (P=0.043). From the analysed texture measures, only the Warner Bratzler Shear Energy values of the cooked meat were affected by the stunning method. These values were higher in the meat of the mechanically stunned groups compared to the electrically stunned rabbits (P=0.042). The percentage of dry matter, crude protein, extractable fat and water to protein ratio, were affected only by the muscle type (P<0.001). To conclude, the rabbit meat was characterised by good quality, with only slight differences between the groups. No differences were found in the stress reaction of rabbits subjected to the examined stunning methods.

Abstract
Abstract
Procedures that result in poor welfare of animals are unacceptable to many people. Consumers have become demanding about the quality of meat, but are also concerned about animal welfare during the production, transport, and slaughter stages. There is a well-known, clear relationship between animal welfare and the quality of animal products. Improper handling of farmed animals contributes to low meat quality. This rule refers to all animals raised for meat, including rabbits. Fasting, loading for transport, long distance transport in difficult environmental conditions, improper stocking density, lying down during transport, lairage, and stunning methods may negatively affect the quality of rabbit meat. A general conclusion from reviewed scientific articles is that many pre-slaughter factors influence the physiological and productive measurements of rabbits, through the effect on their welfare. Because of the complexity of the rabbit meat production chain, the possibility of excluding all the defined stressors is limited.
