Abstract
This study was conducted to evaluate the fatty acid profile, sensory properties and lipid oxidation of meat on retail display (RD) from Nellore steers (n = 96) fed diets containing soybean (SOY), sunflower (SUN), or linseed (LIN) oil or a control diet (CON). After slaughtering, samples of the Longissimus muscle were collected for sensory properties (1 day), fatty acid composition (1 day) and oxidation stability (3 days under RDC) evaluations. No differences in total lipids, cholesterol, TBARS, and total SFAs, MUFAs, PUFAs, and PUFA/SFA were observed. However, meat from animals fed vegetable oil had more CLA than that of the CON samples. The flavour, juiciness and overall acceptability were affected by the treatments (P < 0.05), but no consistent effect of a specific oil source was observed. Meat colour was not affected by diets or days under RD, and 7-ketocholesterol was not detected in any sample. The oil sources used in this work were not effective in consistently changing meat properties.

Stability of vacuum-packed meat from finishing steers fed different inclusion levels of brewer's spent grain. Meat Sci 2018; 147:155-161.

Abstract
Brewer's spent grain (BSG) as a partial substitute for corn silage (CS) was evaluated in finishing feedlot steers on the lipid, protein, color, and microbiological stability of vacuum-packed meat for 75 days under refrigerated storage. Twenty steers were distributed in four treatments in a completely randomized design with five replicates each: 50% concentrate + 50% CS; + 35% CS + 15% BSG; + 25% CS + 25% BSG; and 15% CS + 35% BSG for 90 days. After the animals were slaughtered and the carcasses cooled, the Longissimus thoracis muscle was collected for analyzes. The lipid and protein oxidation, color parameters and microbiological stability of the beef although not affected by the diets (P > .05) oscillated throughout the storage time (P < .05). BSG can be included in the finishing diets of beef cattle by up to 35% (dry basis) and as a forage source without adverse effects on beef shelf life.

Abstract
The effects of restricting iron intake for the final 60 days of a 180-day growth trial on growth performance, nutrient digestibility, slaughter performance and meat quality of dairy bull calves used in veal production were evaluated in this study. Twenty-four newborn Holstein bull calves with an average weight of 41.0 ± 1.62 kg were randomly assigned to two groups of n = 12 calves/group. Calves in the Control group were fed a basal diet that included a milk replacer and pellet feed for 180 days. The iron level in the basal diet was 50 mg/kg. Calves in the Treatment group received the basal diet supplemented with 70 mg/kg iron for the first 120 days, then received the basal diet for the remaining 60 days. Five calves from each group were slaughtered at the end of the trial, and samples of the M. longissimus dorsi and rumen fluid were collected. No differences were found in dry matter intake, growth performance or digestibility and metabolism of nutrients between the two groups (P > 0.05). The dietary iron regimen did not affect the concentrations of blood urea nitrogen, total protein, albumin, or glucose (P > 0.05); however, the haemoglobin content increased with the supplementation of iron in the diet (P < 0.05). Compared with the Control group, increasing dietary iron increased the meat percentage (P < 0.05) rather than the meat nutritional composition or quality of veal.

ASIAN-AUSTRALASIAN JOURNAL OF ANIMAL SCIENCES 2016; 29:1432-42. [PMID: 26954221 PMCID: PMC5003968 DOI: 10.5713/ajas.15.0546] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/30/2015] [Revised: 09/07/2015] [Accepted: 01/08/2016] [Indexed: 12/01/2022]
Abstract
The objective of this study was to determine the effect of palm and/or linseed oil (LSO) supplementation on carcass quality, sensory evaluation and fatty acid profile of beef from crossbred Wagyu beef steers. Twenty four fattening Wagyu crossbred beef steers (50% Wagyu), averaging 640±18 kg live weight (LW) and approximately 30 mo old, were stratified and randomly assigned in completely randomized design into 3 treatment groups. All steers were fed approximately 7 kg/d of 14% crude protein concentrate with ad libitum rice straw and had free access to clean water and were individually housed in a free-stall unit. The treatments were i) control concentrate plus 200 g/d of palm oil; ii) control concentrate plus 100 g/d of palm oil and 100 g/d of LSO, iii) control concentrate plus 200 g/d of LSO. This present study demonstrated that supplementation of LSO rich in C18:3n-3 did not influence feed intakes, LW changes, carcass and muscle characteristics, sensory and physical properties. LSO increased C18:3n-3, C22:6n-3, and n-3 polyunsaturated fatty acids (PUFA), however, it decreased C18:1t-11, C18:2n-6, cis-9, trans-11, and trans-10,cis-12 conjugated linoleic acids, n-6 PUFA and n-6:n-3 ratio in Longissimus dorsi and Semimembranosus muscles.
