ABSTRACT: The aim of this study was to evaluate the carcass characteristics and the physicochemical parameters, centesimal composition, and fatty acid profile of the longissimus lumborum muscle of crossbred steers on a Brachiaria (Syn. Uruchloa) brizantha cv. Marandu pasture during the growing and finishing phases. Twenty-two uncastrated steers ½ Holstein/Zebu, with an average initial weight of 210 kg ± 8.2 kg and eight months of age, were distributed in a completely randomized design, in which the experimental period was fractionated in to three seasons associated with two nutritional plans (NP1 and NP2) and 11 animals by treatment: NP1- mineral mixture ad libitum in rainy seasons + nitrogen/energy supplement at 1 g.kg-1 body weight (BW) in the dry season; and NP2 - nitrogen/energy supplement at 2 g.kg-1 BW in rainy season 1 and in the dry season + nitrogen/energy supplement at 1 g.kg-1 BW in rainy season 2, provided daily at 1000 h. Of the carcass measurements, differences were only observed (p>0.05) between the nutritional plans for loin-eye area corrected for 100 kg of hot carcass weight. Among the physicochemical parameters, only shear force was influenced (p>0.05) by the treatments, with higher values obtained in Nutritional Plan 1. The centesimal composition and fatty acid profile were not influenced (P<0.05) by supplementation. Nutritional plans used in the growing and finishing phases involving low levels of protein-energy supplementation do not lead to changes significant in carcass characteristics and meat. Nutritional Plan 1 is the most appropriate because it presents a lower cost.

The objective of the present study was to evaluate the effects of crossbreeding on the growth, carcass characteristics and meat quality of Chinese native Yanan (YN) pig breed and related crossbreeds, including Duroc × Yanan (DY) and Duroc × (Berkshire × Yanan) (DBY). In total, 60 pigs (20 per breed) were used in the study. The results showed that both crossbreeds, especially DBY pigs, exhibited improved growth and carcass characteristics compared with those of purebred YN pigs. Moreover, the two crossbreeds, especially DBY pigs, produced acceptable meat-quality characteristics (normal pH and meat-colour values, high intramuscular fat content and water-holding capacity, acceptable muscle-fibre parameters, and strong pork flavour) similar to those of YN pigs. M. longissimus lumborum contained eight essential amino acids, with high contents in all pigs. C18:1, C16:0, C18:0, and C18:2 were the main fatty acids in M. longissimus lumborum in the three breeds, and a polyunsaturated:saturated fatty acid ratio of ~0.2 was observed in DBY and YN pigs. These results indicated that DBY pigs exhibit an acceptable total production performance and could be extensively used in commercial pig production to provide high-quality niche products.

Feeding Systems

The goal was to evaluate if feeding systems with or without milk or breed groups can improve carcass characteristics, the proportion of tissues and meat tenderness of feedlot goat kids. Were used 56 animals from five different breed groups fed by experimental diet and milk according to the treatment., without milk or with 1,5 L milk/animal/day. The kid goats were slaughtered at 30 kg of live weight, and the carcass conformation and amount of fat were determined subjectively by visual assessment. Morphometric measurements and carcass and cut yields were performed. The Longissimus lumborum muscle was separated to determinate the area and subsequently it was used to evaluate the tenderness of the meat. The feeding system changes goat carcass characteristics, and goat kids fed milk until slaughter have better carcass yield and meat quality, as it anticipates the deposition of total fat, which can benefit carcass quality, given the scarcity of fat in the carcass of goats. The breed group also influences carcass characteristics. It is recommended the use of the Boer breed up to 3/4, since more than that it reduces leg yield and does not improve the compactness index and carcass conformation.

The objective of this study was to determine the influence of two finishing systems (grain- or grass-finishing) on carcass characteristics, meat quality, nutritional composition, and sensory attributes of bison. Bison heifers were assigned to either a grain- or grass-finishing treatment for 130 days prior to slaughter. Carcass measurements, lean color and fat color were recorded. Striploins (M. longissimus lumborum) were collected for analysis of pH, fatty acid profile, cholesterol, proximate analysis, Warner-Bratzler shear force, cook loss, and consumer sensory evaluation. Grain-finished bison heifers had greater (p < 0.01) hot carcass weights, dressing percentage, ribeye area, backfat, and marbling scores compared to grass-finished heifers. Instrumental color values (L*, a*, b*) of the ribeye and a* value of backfat opposite the ribeye were greater (p < 0.01) for grain-finished heifers. Steaks from grain-finished heifers had increased (p < 0.05) crude protein and fat content and decreased (p < 0.01) moisture compared to grass-finished heifers. The grain-finishing system produced steaks with increased (p < 0.01) cholesterol and total fatty acids (mg/g of wet tissue). The grain-finished system produced more tender (p < 0.05) steaks, but consumer sensory ratings did not differ (p > 0.10) between treatments. These data indicate that finishing systems influence bison carcass characteristics, nutritional composition, and meat quality, but do not translate to differences in consumer preferences.

Physical Attributes

Fallow deer (Dama dama) are important meat producing species providing venison and other products to an international market. The present study investigated the effects of different feed rations on the growth, carcass characteristics and physical attributes of the longissimus lumborum (LL) and semitendinosus (SET) muscles of 45 farm-raised male fallow deer. The animals were divided into three separate groups: 15 pasture-fed (P), 15 pasture-fed and supplemented with barley (B), and 15 pasture-fed and supplemented with barley and lysine (BL). The animals were slaughtered at an average age of 17 months at three time points: after 155, 169 and 183 days on feed. The addition of barley to the feed ration significantly increased weight gain and had positive effects on slaughter and carcass weights, dressing-out proportion, carcass composition, the weight of LL muscle, and increased the redness, yellowness and chroma values of LL muscle. The supplementation with lysine reduced the amounts of carcass and internal fats without compromising other economically important traits.

A total of thirty pigs were experimentally slaughtered using gas (80% CO2 in air, 90 s; 30% CO2/70% N2O; 90 s) or electrical stunning (1.3 A, 10 s). Stunning may accelerate post-mortem muscle metabolism, due to psychological stress and/or muscle contractions. The specific effects of the stunning method were studied by limiting pre-stunning physical activity and stress: pigs were driven in a trolley from the rearing to the stunning site (6.5 m) and immediately slaughtered. Bleeding efficiency and carcass characteristics were similar and satisfactory for all stunning methods. Early post-mortem pH decline in the Longissimus lumborum was faster following gas compared to electrical stunning. The pH of other muscles was not influenced; color and drip loss showed minor effects. Hence, results are in contrast to current beliefs: compared to electrical stunning, following gas stunning, the stress and muscle contractions during the induction of unconsciousness have a slightly greater impact on Longissimus lumborum muscle metabolism; differences are minor and limited to certain muscles only.

The effect of an outdoor-access vs. conventional indoor system on the growth, carcass characteristics, and longissimus lumborum muscle (LL) meat quality was evaluated in 24 Prestice Black-Pied pigs, during the growing-finishing period. Two groups received the same complete diet and were housed separately under conventional indoor conditions, with only one group having full access to pasture (350 m2/pig). The animals showed acceptable growth rates (outdoor vs. indoor, average of 740 g/d vs. 700 g/d), feed intake (average of 2700 g/d), and feed conversion ratios (FCR) (average of 3.3 vs. 3.5). The rearing system significantly affected the fatty acid composition of the LL. Outdoor pigs had lower ratios of n − 6/n − 3 polyunsaturated fatty acids, saturation indexes, atherogenic indexes, and thrombogenic indexes, compared with indoor-raised pigs. No differences were recorded in carcass characteristics, physical meat quality traits (pH45, pH24, drip loss, water holding capacity), or the chemical composition of the meat (crude protein, cholesterol, intramuscular fat, hydroxyproline, and tocopherol). The sensory analysis of grilled LL muscle found that outdoor pigs received lower evaluation scores for tenderness, juiciness, and chewiness, but had a better overall acceptance compared to pigs reared indoors.

El objetivo del presente estudio fue evaluar el efecto de la adición de DL-ácido málico en dietas de borregos Pelibuey en finalización sobre ganancia diaria de peso, características de la canal y componentes que no son parte de la canal. Se utilizaron 16 corderos machos de 27 ± 1.92 kg de peso vivo durante los 48 d de la prueba de alimentación. Los animales fueron alimentados con una dieta alta en energía que contenía rastrojo de maíz, como la única fuente de forraje, con y sin DL-ácido málico (MA). Los animales fueron asignados al azar a uno de los dos tratamientos con 8 borregos cada uno: 1) 4 g de MA por kilogramo de alimento y 2) Control (sin MA). Cuatro borregos de cada tratamiento fueron sacrificados, después de la prueba de alimentación, para medir las características de la canal y los componentes que no son parte de la canal. Los borregos alimentados con MA presentaron una mayor (P<0.05) área del musculo Longissimus lumborum. Sin embargo, no hubo efecto (P>0.05) del MA sobre la ganancia diaria de peso y peso de los componentes que no son parte de la canal. En conclusión, la adición de 4 g de DL-ácido málico, en alimento con alto contenido energético, promueve el crecimiento muscular lo que mejora la calidad de la canal de los borregos en finalización.
