“…There was no difference in instrumental tenderness observed among treatments in this study. This is in agreement with other studies that also reported no difference in instrumental tenderness between grass-fed and grain finished beef [ 95 , 96 , 97 ]. However, other studies have shown that tenderness is inversely related to age, with tenderness decreasing as age increases [ 98 , 99 , 100 ].…”

Consumer interest in grass-fed beef has been steadily rising due to consumer perception of its potential benefits. This interest has led to a growing demand for niche market beef, particularly in the western United States. Therefore, the objective of this study was to assess the impact of feeding systems on the change in microbial counts, color, and lipid oxidation of steaks during retail display, and on their sensory attributes. The systems included: conventional grain-fed (CON), 20 months-grass-fed (20GF), 25-months-grass-fed (25GF) and 20-months-grass-fed + 45-day-grain-fed (45GR). The results indicate that steaks in the 20GF group displayed a darker lean and fat color, and a lower oxidation state than those in the 25GF group. However, the feeding system did not have an impact on pH or objective tenderness of beef steaks. In addition, consumers and trained panelist did not detect a difference in taste or flavor between the 20GF or 25GF steaks but expressed a preference for the CON and 45GR steaks, indicating that an increased grazing period may improve the color and oxidative stability of beef, while a short supplementation with grain may improve eating quality.

“…Samples were dried and milled using a Wiley Mill No1 (Arthur Thomas Co, Philadelphia, USA) through a 2‐mm screen to determine DM and nitrogen (AOAC, ); and intramuscular fat (IMF) was measured using the Soxhlet petroleum‐ether extraction method for 8 hr of a lyophilized sample (Anonymous, ). Shear force was measured to determine mechanical tenderness (C‐LM 3B Digital Display Muscle Tenderness Meter, Harbin, China) according to the modified Warner‐Bratzler method (Manni, Rinne, Huuskonen, & Huhtanen, ). Six cylindrical samples of 1.5 cm diameter were collected from a steak of 2.5 cm thick from each yak for the measurement.…”

Heat‐treated rapeseed was supplemented to indoor fed yaks in winter to test the effect on dry matter intake (DMI), body mass change, and meat quality. Sixteen 3‐year‐old yak steers (124 ± 15.3 kg) were divided randomly into two groups and were offered either heat‐treated rapeseed (HTR) or rapeseed meal (CONT). The yaks were allowed 14 days for adjustment and measurements were made over 120 d. There was no difference in DMI between groups (p = 0.67), but average daily gain tended to be higher (p < 0.056) and feed to gain ratio tended to be lower (p = 0.050) in HTR than in CONT yaks. Meat from HTR yaks was more tender (p = 0.006), had higher intramuscular fat (p = 0.013), and had lower cholesterol content (p = 0.009) than from CONT yaks. In addition, the atherogenic index was lower (0.37 vs. 0.43; p = 0.049), the PUFA:SFA ratio was higher (0.55 vs. 0.37; p = 0.049), and the n‐6:n‐3 (n‐6 PUFA to n‐3 PUFA) ratio was lower (2.76 vs. 4.78; p = 0.003) in HTR than in CONT yaks, which all favoured the HTR yaks. Meat from HTR yaks met human health standards of a PUFA:SFA ratio of above 0.4 and n‐6:n‐3 ratio of less than 4, whereas meat from CONT yaks just missed these standards.

“…The carcass and meat quality of ruminants is affected by many factors (Dannenberger et al 2006), and of these, diet is likely the foremost. The previous studies reported that bulls could adapt to different feeding strategies without significant effect on meat quality (Manni et al 2018). Also, Alfaia et al (2009) considered that a high-forage diet had nutritional advantages for ruminants and conducive for the activity of cellulose-decomposing bacteria, which synthesized intermediate isomers, biohydrogenated intermediate isomers trans11-18:1 (t11-18:1) and cis9, trans11-18:2 (c9, t11-18:2) and n-3 polyunsaturated fatty acid (PUFA) of meat.…”

Carcass parameters, meat quality, fatty acid profile, and amino acid composition of Simmental bulls fed a diet based on various forage silages (VS) compared with the one based on only corn silage (CS) were investigated. A total of thirty male Simmental (440.5 ± 11.5 kg) was selected and assigned randomly divided into two treatments. All animals were fed twice daily (0700 and 1700 h) and water was supplied ad libitum, feed considering 5 to 10% refusals. The period of 207 days fattening trial was divided into three stages as P1 (1 to 64 days), P2 (65 to 130 days), P3 (131 to 207 days). Six beef cattle were slaughtered from each group at the end of the experiment. Substituting CS with VS in the finishing diet did not have a significant effect on slaughter performance, nutrient content, fatty acids, and amino acids profile (P > 0.05). However, the intramuscular fat and connective tissue content of the VS diet was lower compared with the CS diet (P < 0.05). Also, beef cattle fed VS diet could improve eye muscle area, increase histidine content and diameter of muscle fiber. In conclusion, substituting corn silage with various forage silages in the diet of beef cattle could potentially reduce the negative effect under the studied conditions. © 2021 Friends Science Publishers
