“…The water loss rate was determined as the percentage difference in weight following 24-h period during which samples were suspended within inflated plastic bags at 4°C ( Forwood et al, 2021 ). The cooked meat rate was calculated according to the percentage difference in weight between pre- and post-cooked meat samples ( Needham et al, 2019 ). The fatty acids methyl esters were measured according to the AOAC (2005) and Bu et al (2021) methods with a gas chromatography–mass spectrometer 7890B (Agilent, California, United States).…”

This study aimed to investigate the effects of replacing alfalfa with native grass on growth performance, meat quality, and rumen microbiota of lambs. Forty-five 6-month-old Ujimqin lambs with live body weight (BW) of 29.50 ± 0.26 kg were used for the experiment, and the lambs were assigned to three diet treatments (three pens per treatment and five lambs per pen) with 30 square meters per pen in semi-open housing based on similar BW. The lambs have received 30% alfalfa (HA, high alfalfa percentage group), 20% alfalfa (MA, moderate alfalfa percentage group), and 10% alfalfa (LA, low alfalfa percentage group) diets, respectively (dry matter basis). The diet treatments had a significant (P < 0.05) influence on the dry matter intake of lambs and the dry matter intake increased with the increasing percentages of native grass hay, while the significantly (P < 0.05) lower final BW and average daily gain were observed in the MA and LA groups compared with that in the HA group. The diet had a significant (P < 0.05) difference in meat pH value, water loss rate, cooked meat rate, moisture, and intramuscular fat, while no significant (P > 0.05) difference was found in protein. As native grass hay percentages increased in the diet, the contents of palmitic (C16:0) and palmitoleic (C16:1 cis-9) in the HA and MA groups were significantly (P < 0.05) lower than that in the LA groups, and compared with the HA group, the contents of elaidic (C18:1 trans-9), oleic (C18:1 cis-9), and linoleic (C18:2 cis-9–cis-12) were significantly (P < 0.05) increased in the MA and LA groups. The content of α-linolenic (C18:3n3) was significantly (P < 0.05) higher in the LA group than that in the HA and MA groups. The principal coordinate analysis profile displayed that the composition of the bacterial community of these groups was distinctly separated from each other. No significant (P > 0.05) difference was observed in the dominant rumen bacteria at the phyla and genus levels. In conclusion, the meat quality and fatty acid profile analysis revealed that replacing alfalfa hay with native grass hay is more beneficial for Mongolian lambs, and the meat from LA diet treatment is better than the others. In addition, correlation analysis of the association of rumen microbiome with growth performance, meat quality, and fatty acid profile provides us with a comprehensive understanding of the composition and function of rumen microbiota. These findings could provide knowledge of how the diet affects the animal performance, meat quality of lambs, and microbiota of the rumen, laying a theoretical basis for replacing alfalfa with native grass.

“…Meat color as lightness (L*), redness (a*), and yellowness (b*) was measured after exposure to air for 45 min by a portable colorimeter (CR-13, Konica-Minolta Sensing Inc., Japan) as described [7] . The variables L*, a*, and b* were measured 5 times each, and the measures were averaged before statistical analysis.…”

This study primarily compares the carcass and meat quality traits of yaks of different ages and genders. Measurements of carcass weight and characteristics were taken for male and female Gannan yaks aged 1-2, 2-4, 4-6, and 6 years and older. Additionally, the weight and meat quality of 9 major cuts were measured. The results indicated significant variations in various aspects of yak carcasses around the age of 4, and substantial differences between male and female yaks after the age of 4. Different body regions showed distinct meat quality. The tenderness of the tenderloin is the highest (P < 0.05), while the striploin is the lowest (P < 0.05), and the protein content of the hindquarter cuts is higher. Principal component analysis (PCA) was employed to identify key factors significantly affecting total meat yield. Subsequently, predictive models for total meat yield were developed for yaks aged 1-4 years, 4+ years for males, and 4+ years for females based on these factors. Furthermore, the meat from the 9 major cuts was classified according to its intrinsic meat quality traits, which holds significant reference value for the assessment of yak carcass yield grades and the grading of quality in meat cuts, ultimately contributing to the realization of the full potential of the yak meat industry.

“…The meat from common eland aligns well with the expectations of the health-conscious consumer internationally, being low in intramuscular fat [ 21 ] with a higher proportion of polyunsaturated fatty acids compared to beef cattle fed the same diet [ 22 ]. Recent research has shown that common eland meat flavor resembles that of beef [ 23 ], but that its tenderness should be improved through processing techniques such as pelvic-suspension and wet-ageing before commercial sale [ 24 ]. Immunocastration has also been utilized as a management strategy in mixed-sex eland herds [ 20 ], with little effect seen on the physical and sensorial meat quality [ 24 ].…”

This study investigated the effects of immunocastration and slaughter age on the carcass yield performance of intensively farmed common eland males. Eighteen male eland (five immunocastrated juveniles, three intact juveniles, five immunocastrated sub-adults, and five intact sub-adults) were finished for four months, after which their carcass, offal, primal cut, and individual muscle yields were determined. Juveniles were ~6 months of age at the start of the experiment, while sub-adults were ~1.5 years old. Primal cuts were dissected to determine the percentage yields of meat, bones (with tendons), separable fat, and trimmings. Immunocastration had no effect on offal or carcass yields. While sub-adults had increased individual muscle yields, juveniles had greater proportionate yields of primal cuts and a greater total high-value: low-value meat ratio. Whilst slaughtering younger male eland could provide additional economic advantages, this should be considered being against changing marketing trends.
