Carcass traits and meat quality of steers on pasture submitted to different dietary supplementation

This study aimed at evaluating carcass traits and meat quality of Nellore steers on pasture submitted to different dietary supplementation strategies. The 32 Nellore animals tested (8 ± 0.6 months) were raised under rotational grazing on Brachiaria brizantha cv. Piatã (syn. Urochloa brizantha cv. Piatã) pasture and distributed in four treatments: supply of mineral salt ad libitum in the growth and finishing phases (MSGF); concentrate supplementation only during the growth phase (CG); concentrate supplementation only during the finishing phase (CF) and concentrate supplementation the growth and finishing phases (CGF). The concentrated supplement was supplied at 0.5% of body weight and mineral ad libitum. The steers were slaughtered when more than 50% of the lot of each treatment reached 450 kg body weight. The mean the hot and cold carcass weight and subcutaneous fat thickness did not differ between treatments (P > 0.05). The calves the treatment CF and CGF showed a larger rib-eye area and higher ether extract levels in the Longissimus dorsi muscle than in MSGF and CG (P < 0.05). Mean shearing force was similar between treatments (P > 0.05). The use of feeding strategies on pasture with concentrate supplementation in the growth and finishing phases of Nellore cattle anticipates slaughter in 92 days and produces carcasses and meat with satisfactory traits.

The aim of this study was to evaluate the effects of including cashew bagasse bran (CBB) as a food ingredient in qualitative feed restriction programs on the carcass traits and meat quality of barrows and gilts. Twenty–four crossbred pigs (12 barrows and 12 gilts) were used, with an average initial body weight of 57.93 ± 3.67 kg/LW. The experimental design was a randomized block 3x2 factorial arrangement with three levels (0%, 15% and 30% CBB), two sexes (barrows and gilts) and four repetitions. The treatments were composed of the basal diet (BD) formulated with corn, soybean meal and a commercial base mix for finishing pigs, to which different levels of CBB were added. At the end of the trial period, the animals were slaughtered for the evaluation of the meat quality and carcass traits. The inclusion of CBB in the diets did not affect the carcass traits of the gilts but affected the carcass traits of the barrow positively, increasing theyield of meat in the chilled carcass and reducing the thickness of subcutaneous fat. In the longissimus dorsi muscle and in the adipose tissue of the pigs, the myristic (C14:0), palmitoleic (C16:1), oleic (C18:1), linoleic (C18:2), linolenic (C18:3) and arachidonic (C20:4) fatty acids were evaluated, and no effect was observed (P > 0.05) from the levels of CBB in the diets. In the comparisons between the sexes, a greater concentration of C20:4 fatty acid was observed in the carcass of the gilts. In this context, CBB was considered for use as a feed ingredient in programs of qualitative feed restriction for finishing pigs.

Practical Significance

The aim of the present study was to evaluate the fatty acid composition of meat and subcutaneous fat, carcass traits and meat quality of Nellore steers fed diets supplemented with various lipid sources. Forty-five young bulls, with average bodyweight of 441 ± 30 kg, were allotted into 10 paddocks, with five treatments, each consisting of two paddocks. The bulls were randomly assigned into one of the following five treatments, which consisted of four lipid sources: palm oil (PO), linseed oil, rumen protected fat (soybean-based oil), whole soybean, and a control (without additional fat). Trial duration was 120 days, which included 30 days of adaptation. Supplements were offered daily at 10 g/kg bodyweight per day. Dietary supplements for providing additional fat were formulated to consist of 10% ether extract. Lipid sources did not significantly affect the average daily gain (P = 0.797) or dressing percentage (P = 0.663). Supplementation with PO increased the concentrations of lauric acid (P = 0.036) and myristic acid (P < 0.001) in the muscle and subcutaneous fat. Animals supplemented with linseed oil had significantly higher concentrations of conjugated linolenic acid in the meat (P = 0.036) and fat (P = 0.049) than did control animals. In the present study, the use of various lipid sources in dietary supplements of grazing cattle during finishing period did not affect carcass traits or physical attributes of beef. This absence of statistical significance may be related to the minimum number of repeat paddocks (2) per treatment. Thus, differences that can have a practical significance were not evidenced by statistical analysis. The inclusion of PO and protected fatty acids derived from soybean oil (rumen-protected fat) is not recommended as a method to improve the lipid profile of meat and subcutaneous fat of Nellore cattle.

This study aimed to evaluate the effect of pre- and post-calving feed restriction on quantitative characteristics and lipid profile of meat from Morada Nova sheep. Twenty-four male lambs from single births only, with an initial weight of 10.0 ± 3.07 kg and at four months of age, were distributed in a randomized complete design, into three groups: pre-calving restriction (R-PRE; n=8) post-calving restriction (R-POS; n=8), and ad libitum feeding (ADLI; n=8). To make up the experimental treatments, the feeding regime applied previously on the sheep in the last third of pregnancy was considered. Treatments ADLI and R-POS were composed of lambs born from ewes fed ad libitum in the last third of pregnancy. Treatment R-PRE consisted of lambs born from ewes subjected to feed restriction in the last third of pregnancy at 60% of the recommended requirements for the group of ewes feeding ad libitum. For the lambs from treatments ADLI and R-PRE, the diet was supplied allowing 20% of the total supplied as refusals. For the animals from R-POS, a 30% restriction was imposed in relation to the animals feeding ad libitum. Animals were slaughtered with an average live weight of 25 kg. Afterwards, carcasses were chilled at 4 ºC for 24 h. Meat quality measurements were taken on the right side of each carcass; pH was determined immediately after slaughter and then again after chilling. Samples of the longissimus dorsi muscle were collected and frozen at -20 ºC. Moisture, ash, protein, total lipids, water-holding capacity, and cooking loss were determined in the meat samples, which were then subjected to the shear-force test. The sensory analysis was determined by the hedonic-scale test, in which sensory parameters of tenderness, juiciness, flavor, aroma, and overall acceptability and fatty acid profile were evaluated. There was a feed-restriction effect on protein, lipids, and water-holding capacity (P0.05). Saturated fatty acid contents were affected by the treatments (P0.05). Feed restriction does not compromise the physicochemical or sensory quality of Morada Nova lambs meat, but rather provides a meat product of good acceptance.

Abstract. The nutritional requirements can be met, and carcass quality can be achieved by using concentrate supplementation in the diets of grazing lambs. This study evaluated the effects of different concentrate supplementation rates (0 %, 1.5 %, and 3 % of body weight) and tropical pastures (Panicum maximum cv. `Aruana' and Brachiaria brizantha cv. `Marandu') on lamb carcass traits. Thirty-six male Suffolk lambs, with an initial body weight of 22.54 ± 2.72 kg, were evaluated in a 3 × 2 factorial experimental design. The concentrate used consisted of milled soybean, maize, and oat grains. The pasture species affected empty body weight and commercial cuts. The use of concentrate supplementation affected carcass weight, yield, indexes, and commercial cuts. Also, the use of concentrate supplementation improved the weight of muscle and fat content. Based on discriminant analysis it is possible to identify the rearing systems, when all variables where used, or the level of concentrate supplementation when variables of weight were used. Carcasses of animals on grass-only diets were different and easier to discriminate. The use of concentrate supplementation on rearing lambs improves the quality of carcass traits. The period of finishing can be shorted with supplementation of 3 % of body weigh in Aruana and Marandu grass. The discriminant analysis can identify the differences between rearing systems based on all carcass traits. This analysis can be used to develop carcass traceability systems.

The aim of this study was to evaluate the effect of production system on the health, performance, carcass characteristics, and meat quality of autumn born (AB) and spring born (SB) Holstein bulls. The study involved a total of 224 Holstein bulls and was conducted over two years (2017/18, 2018/19). The four production system treatments differed during the grower period and consisted of: (i) grazed with no concentrate supplementation (G), (ii) grazed with 2 kg concentrate supplementation per day (G2), (iii) grazed with ad libitum access to concentrates (GA) and (iv) housed with ad libitum access to concentrates and grass silage (HA). All bulls were finished on ad libitum concentrates and grass silage and were slaughtered at a mean age of 15.5 months. Total grower dry matter intake (DMI) (p < 0.001) and total finishing DMI (p < 0.001) differed between production systems for both AB and SB bulls, with that of GA bulls being the greatest in both cases. Average daily gain (ADG) during the grower period was greatest (p < 0.001) for the HA production system in the AB bulls and the GA and HA production systems for the SB bulls. However, during the finishing period, G bulls had the greatest (p < 0.001) ADG of the AB bulls, while that of the SB bulls was from the G2 production system (p < 0.001). For both AB and SB, bulls on the GA and HA production systems produced heavier cold carcass weights than the G and G2 bulls (p < 0.001). There was no significant difference (p > 0.05) in health, carcass conformation, fat classification, or meat quality between production systems.

Abstract. The aim of the experiment was to compare the weight gain, carcass traits and meat quality of Hyplus hybrid (HH, offspring of Hyplus PS59 bucks and Hyplus PS19 does, n = 77), purebred Pannon White rabbits (PP, offspring of Pannon White bucks and Pannon White does, n = 84) and their crossbreds (PH: offspring of Pannon White bucks and Hyplus PS19 does, n = 97; HP: offspring of Hyplus PS59 bucks and Pannon White does, n = 79). Pannon White rabbits are selected for body weight gain and for carcass traits by computerised tomography (CT), while Hyplus PS19 females and Hyplus PS59 males are selected on prolificacy and body weight gain, respectively. Rabbits of HP genotype had the highest while those of PP genotype the lowest body weight gain (38.9 and 36.6 g/day, respectively; P<0.05). Pannon White breed had an advantageous influence on dressing out percentage (PP: 58.0%; PH: 58.7%; HP: 57.7%; HH: 57.6%; P<0.001) and on the weight of the m. Longissimus dorsi (PP: 152 g; PH: 143 g; HP: 137 g; HH: 136 g; P<0.001). The fat content of the carcass was lower in the offspring of the Hyplus PS59 bucks (1.15, 1.16, 0.89 and 0.85% for PP, PH, HP and HH rabbits, respectively; P<0.001). Significant differences were found between the meat samples of progenies of purebred Pannon White and the hybrid terminal cross rabbits in the moisture and fat content of hindleg meat (moisture content: PP: 75.5%, HH: 76.1%, P<0.05; fat content: PP: 2.38%, HH: 1.46%; P<0.001). From the view point of dressing out percentage and the volume of the m. Longissimus dorsi the usage of Pannon White genotype is advantageous. Dressing out percentage of the offspring of the early-matured Hyplus PS19 does and Pannon White bucks selected with the help of computerised tomography is remarkable.
