The aim of this trial was to determine the effect of the presence of wire or plastic mesh elevated platforms on carcass traits and meat quality characteristics, with particular attention to the oxidative status of growing rabbits. A total of 174 five-week old rabbits were randomly divided into 3 groups with 2 replications (6 pens; 29 rabbits/pen): pens without platforms (NoP) with a stocking density of 16 rabbits/m2 and pens with wire-mesh platforms (WP) or plastic-mesh platforms (PP) that were placed on 2 levels, with a stocking density of 16 rabbits/m2 on the floor or 9.14 rabbits/m2 when the platform were included. At 84 d rabbits were slaughtered. The slaughter traits and Longissimus lumborum (LL) physical and chemical compositition were not affected by treatments. Rabbits from the PP group showed the highest retinol and γ-tocotrienol content on LL muscle, whereas the NoP ones showed a higher α-tocotrienol and α-tocopherol level. The absence of platforms led to decreased (P<0.001) thiobarbituric acid-reactive substances values and induced an improvement in n-3 polyunsaturated fatty acids. Levels of linoleic, linolenic and docosahexaenoic acids were equal to those of the WP group (23.45, 3.75, 0.64% in NoP and 22.6, 4.14, 0.53% in WP, respectively) but higher than in PP rabbits (20.86, 3.05, 0.45%, respectively). It can be concluded that the pens with elevated platforms provide greater possibilities for movement, which is beneficial from the viewpoint of animal welfare. However, this greater activity influences the oxidative status of the meat, decreasing the antioxidant content and worsening the lipid oxidation of rabbit meat.

<p>The aim of this trial was to study the effect of an alternative housing system on the oxidative status and meat quality of fattening rabbits. From May to June 2014, 60 rabbits of 35 d of age were reared in Mobile Arks (MA) placed on alfalfa grass and frequently moved for 40 d. To assess the health status of animals, blood samples were collected at slaughter in MA and in conventional cages (C). Meat quality parameters were also evaluated. Concerning the <em>in vivo </em>oxidative status, ark-reared rabbits showed higher thiobarbituric reactive substances values than C ones, probably for the higher motor activity due to the larger living area. The lipid percentage of <em>Longissimus lumborum </em>muscle was lower (1.22 <em>vs. </em>1.48%) in the ark group. There were no significant differences in the muscle pH, colour, water holding capacity and cooking loss. Given the higher intake of grass, rich in vitamins, carotenes, polyphenols and polyunsaturated fatty acids, the antioxidant content of meat was higher in ark-reared rabbits (7.42 <em>vs. </em>6.82 µg/g of retinol, 719.2 <em>vs. </em>683.3 ng/g of α-tocopherol, respectively). Even the fatty acid profile of MA rabbits reflected the higher intake of essential fatty acids from grass and the n-3 long chain polyunsaturated fatty acids (arachidonic acid, eicosapentaenoic acid and docosahexaenoic acid) were almost doubled. Our study suggested that the fattening of rabbits in ark system could be a possible alternative system to improve the meat quality of rabbits.</p><p><strong><br /></strong></p>

<p class="Articletitle">The effect of sorghum hydrolysed by <em>Trametes maxima</em> CU1 and <em>Pycnoporus sanguineus</em> CS2 was evaluated on growth performance traits and rabbit meat quality. A total of 24 unsexed New Zealand rabbits, weaned at 20 d of age, were allocated to 2 treatments: T1 (diet including 300 g/kg of non-hydrolysed sorghum) and T2 (diet including 300 g/kg of hydrolysed sorghum by <em>Trametes maxima</em> CU1 and <em>Pycnoporus sanguineus</em> CS2). Rabbits of group T2 did not have significantly different (<em>P</em>&gt;0.05) feed intake compared to those in T1. Carcass traits were also not significantly different (<em>P</em>&gt;0.05) between the 2 groups. The pH, water-holding capacity, colour and cooking loss of the longissimus lumborum were not different (<em>P</em>&gt;0.05) between treatments, whereas the pH of the rabbits biceps femoris was higher in T2 (6.21; <em>P</em>&lt;0.05) than in T1 (6.14). Meat hardness and gumminess in T2 were lower (<em>P</em>&lt;0.05) in comparison to meat from T1. Thus, sorghum hydrolysed by <em>Trametes maxima</em> CU1 and <em>Pycnoporus sanguineus</em> CS2 contributed to a better rabbit meat texture.</p>

AbstractProcedures 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.

Dietary Treatments

There is a growing demand by the modern consumer for meat containing less fat and lower levels of saturated fatty acids, which are considered to increase the risk of coronary heart disease. In southern Italy, the Gentile di Puglia breed is one of the most common on farms, and the light lambs are often consumed. The study evaluates the effect of a diet containing extruded linseed (Linum usitatissimum) on growth performances, carcass traits, and meat quality in Gentile di Puglia light lambs. Thirty-six male lambs are weaned at about 20 days of age, and divided into three groups—each group is either fed a control diet (C), a diet containing 3% extruded linseed (L), or a diet containing 3% extruded linseed and 0.6% oregano (Origanum vulgare) (L + O). The lambs’ growth performances and the slaughtering and dissection data did not differ between groups. Dietary treatments have no significant effect on the quality and chemical composition of Longissimus lumborum (Ll). The mount of linoleic acid in Ll meat is significantly higher in the L group, and this positively affected the total content of n-3 Polyunsaturated Fatty Acid, as well as the n-6/n-3 ratio. The good results obtained concerning the sensory traits meet the requirements of the market’s consumer.

Abstract This study evaluated the effect of roughage:concentrate (R:C) ratio associated with a variable particle size of physically effective neutral detergent fibre (peNDF8) in the forage (Tifton-85 hay) on the performance, carcass traits and meat quality of lambs. Seventy-two 4-month-old, non-castrated Santa Ines male lambs (23.5 ± 2.32 kg BW) were distributed in a completely randomized design, in a 2 × 2 factorial arrangement [two peNDF8 hay particle sizes (13 and 6 mm) and two R:C ratios (700:300 and 500:500 g/kg DM total)]. DMI, DM, NFC and TDN digestibility's, N-intake and N-faecal excretion were affected by the R:C ratio (P < 0.05). However, the N-retained was not affected by the studied variables (P > 0.05). It was observed an interaction (P < 0.05) between the peNDF8 and R:C ratios for final BW, average daily gain (ADG), colour parameters and pH 24 h. The lower roughage ratio provided greater (P < 0.05) concentrations of C14:1, C16:1–cis9, C18:1–cis9, ΣMUFA, Σn–6:Σn–3 and hypocholesterolemic/hypercholesterolemic index, enzymatic activity Δ9desaturase-C16 and -C18. Lambs fed a lower roughage diet had improved performance and feed efficiency, however, presented reduced polyunsaturated fatty acids (PUFA) concentrations in the meat, especially Σn–3 family. Higher roughage diet and larger peNDF8 particle size improved the concentrations of PUFA while decreased Σn–6:Σn–3 ratio in meat. Larger peNDF8 particle size associated with higher roughage proportion, have reduced animal performance however, it increased protein concentration, a* and C* colour parameter without affecting fatty acids profile of Longissimus lumborum muscle.
