“…Though the relative ratio of myofibers with different metabolic properties is determined by genetic factors, it is also susceptible to physiological and nutritional alterations [ 112 ]. Fast-growing animals are characterized with increased ratios of glycolytic myofibers [ 113 , 114 ]. Increased dietary energy levels are also positively related to the switch of myofiber metabolism from oxidative phosphorylation to glycolysis in beef cattle [ 115 , 116 ].…”

Over the past few decades, genetic selection and refined nutritional management have extensively been used to increase the growth rate and lean meat production of livestock. However, the rapid growth rates of modern breeds are often accompanied by a reduction in intramuscular fat deposition and increased occurrences of muscle abnormalities, impairing meat quality and processing functionality. Early stages of animal development set the long-term growth trajectory of offspring. However, due to the seasonal reproductive cycles of ruminant livestock, gestational nutrient deficiencies caused by seasonal variations, frequent droughts, and unfavorable geological locations negatively affect fetal development and their subsequent production efficiency and meat quality. Therefore, enrolling livestock in nutritional intervention strategies during gestation is effective for improving the body composition and meat quality of the offspring at harvest. These crucial early developmental stages include embryonic, fetal, and postnatal stages, which have stage-specific effects on subsequent offspring development, body composition, and meat quality. This review summarizes contemporary research in the embryonic, fetal, and neonatal development, and the impacts of maternal nutrition on the early development and programming effects on the long-term growth performance of livestock. Understanding the developmental and metabolic characteristics of skeletal muscle, adipose, and fibrotic tissues will facilitate the development of stage-specific nutritional management strategies to optimize production efficiency and meat quality.

“…The frame size category of beef cattle can affect growth and carcass formation. Differences in fat, muscle, and bone composition for small, livestock size category can affect growth and carcass formation.having a genetic factor of relatively fast body weight growth compared to small to medium-sized beef cattle, this must be supported by good environmental factors (feed and maintenance systems) (Beline et al, 2021;Murray et al, 2021).…”

This research aims to determine the quantitative characteristics of Brahman cross heifer cattle's carcass and wholesale cut at different age levels. The number of heifer cattle taken as samples was 104 heifer. The research method used is a case study with the selection of locations by purpose sampling. Direct observation is used to obtain information on age, slaughter weight, carcass weight, wholesale cut weight, and parts thereof (primary, secondary, and manufacturing cut). The data obtained were then analyzed by analysis of variance (ANOVA). If there was a significant difference, it is followed by a further test of the Least Significant Difference (LSD). The results showed that the age levels in slaughter had a significant effect (P<0.05) on the slaughter weight, fresh carcass weight and wilted carcass weight, but had no effect on the percentage of carcass and wholesale cut. The older the age of cattle and the longer the cattle are raised, the higher their body weight will affect the slaughter weight produced, and the higher the slaughter weight, the higher the carcass weight made. Average slaughter weight at different age by Permanent Incisor (PI): PI0 (<18 months), PI2 (18-24 months) and PI4 (24- 36 months). While the average percentage of heifer carcass at different age levels was relatively the same (52,71% : 53,04% : 53.10%). The weight and rate of wholesale cut and its parts are also somewhat the same. The research results show that the slaughter age affects the slaughter weight and carcass weight but not dressing percentage and wholesale cut weight. Brahman cross heifer cattle at PI4 produced optimal carcass weight and wholesale cut.

“…As described earlier, NC animals have more testosterone than CA, and a higher fiber hypertrophy, promoted by testosterone, is expected in these animals, and might have caused a reduction in tenderness of meat from NC. Results found by Maltin et al (1998), Renand et al (2001), andBeline et al (2021), showed a lower tenderness in meat from muscles with larger fiber sizes. In addition, a higher muscle hypertrophy in intact males supported by an increase calpastatin activity may reduce postmortem tenderization (Morgan et al, 1993), resulting in less tender beef.…”
