“…This result supports the significant ( p < 0.01) correlation between those variables (r values between 0.69 and 0.96 for LM depth and 0.87 and 0.95 for SF; data not shown). These results show that the RTU technique helps obtain in vivo information related to carcass traits, as discussed in previous works on RTU for different meat species [ 33 , 34 , 35 , 36 ]. Specifically, for cattle, there are multiple studies in which the RTU technique was used to estimate carcass characteristics [ 37 , 38 , 39 ].…”

Arouquesa is an autochthonous bovine breed known for its Arouquesa PDO beef labeling. There are several production systems under the definition of PDO labeling. This study aimed to compare the effect of different production systems on carcass and meat traits for the Arouquesa breed. Two trials differing in diet and weaning age were conducted. The first trial included a TF group fed the traditional way and weaned at 9 months; a TF + S1 group, equal to TF, but with a starter supplement; and finally, a S1 + S2 group that was fed with a starter and a growth supplement and weaned at 5 months. The second trial was composed of a TF + S3 group fed like the TF + S1 group but reared until 12 months with a finishing supplement, and finally, the S3 group fed like the S1 + S2 group but reared until 12 months. In the first trial, the TF + S1 and S1 + S2 groups showed higher final live weight and average daily gain. In the second trial, we observed differences in the subcutaneous fat that was higher in the S3 group. Regarding meat traits, we observed differences in exudative and cooking losses in the first trial. In general, supplementation improved meat production without affecting meat quality parameters.

“…The most interesting solutions utilize image capture and analysis as vision-based body condition scoring systems, which somewhat mimics the traditional BCS assessment. Another imaging approach that has been used to measure body and carcass composition is ultrasound [ 114 ]. This technique has been widely used to monitor body condition in small ruminants [ 115 , 116 ], in swine [ 117 ], and in cattle [ 118 ].…”

Specific animal-based indicators that can be used to predict animal welfare have been the core of protocols for assessing the welfare of farm animals, such as those produced by the Welfare Quality project. At the same time, the contribution of technological tools for the accurate and real-time assessment of farm animal welfare is also evident. The solutions based on technological tools fit into the precision livestock farming (PLF) concept, which has improved productivity, economic sustainability, and animal welfare in dairy farms. PLF has been adopted recently; nevertheless, the need for technological support on farms is getting more and more attention and has translated into significant scientific contributions in various fields of the dairy industry, but with an emphasis on the health and welfare of the cows. This review aims to present the recent advances of PLF in dairy cow welfare, particularly in the assessment of lameness, mastitis, and body condition, which are among the most relevant animal-based indications for the welfare of cows. Finally, a discussion is presented on the possibility of integrating the information obtained by PLF into a welfare assessment framework.

“…In addition, we confirmed that the use of RTU measures is a practical and easy technique for in vivo carcass traits prediction because it is not harmful and less stressing to the rabbit. Although studies are scarce, RTU measurements are a useful tool that has a relevant role in evaluating in vivo carcass characteristics in rabbits with special focus on muscle weight (Silva et al, 2009;Silva and Stouffer, 2019).…”

Background. Carcass yield varies depending on the relative proportions of muscle, fat and bone, therefore, the possibility of predicting its value would produce valuable information that will promote the viability and sustainability of rabbit meat production. Methodology. Thirty-eight male growing rabbits (New Zealand White × Californian) with body weights (BW) of 1329 ± 291 g and from 60 to 100 days of age were used. Real time ultrasonography (RTU) measurements were taken 12 h before slaughtering. For that, rabbits were shaved between the 6th and 7th lumbar vertebrae. The longissimus thoracis et lumborum muscle (LM) area (LDA) and also the maximum LM width (LDW) and the maximum depth LM (LDD) were measured. Data recorded at slaughtering included carcass and non-carcass components. After chilling at 4° C for 24 hours, carcasses were split longitudinally to obtain left and right halves that were later weighed. Thereafter, the right half carcass was weighed and manually deboned for recording weights of muscle (TCM), and bone (TCB). Results. The highest correlation (r = 0.84, P <0.001) was observed between TCM and LDD, while the lower correlation (r = 0.4, P <0.001) was observed between TCB and LDW. The BW were highly related to carcass characteristics (r>0.77≤0.97). In vivo RTU measurements explained a low to moderate amount of variation in TCB and TCM with an r2 of 0.36 to 0.77 (P < 0.001) respectively. BW explained from 49 to 92% of variation in TCB and TCM, respectively. Implications. The in vivo ultrasound measurements it is a viable tool that allows predicting carcass value of rabbits. Conclusion. Our results indicated that the use of RTU measurements could accurately predict muscle from growing rabbit's carcass.
