“…These results are in accordance with that of Walz et al (1998) in which the inclusion of 0.75% clay mineral to lamb diets had no significant effect on longissimus muscle area, backfat thickness, and yield grade. Constantino et al (2014) did not observe any significant difference in cold carcass weight, marbling, and fat thickness in ewes supplemented with magnesium oxide.…”

ABSTRACT. Thirty-six castrated, seven months-old Hanwoo steers (initial body weight: 184 ± 5.2kg) were assigned to three treatments over 23 months to evaluate the effects of supplementation with bentonite (0, 0.1 and 0.3%) on growth performance and carcass and meat characteristics. A completely randomized design with three replicates was used. The inclusion of a bentonite-supplemented diet had an influence on final weight, total weight gain, and average daily gain. Bentonite supplementation had no significant effect on proximate composition and meat quality. For carcass characteristics, there were no significant differences in yield traits and quality traits between treatments (but not cold carcass weight, marbling score, and quality grade). It was concluded that supplementation with bentonite (0.1 and 0.3%) improved growth performance, cold carcass weight, marbling score and quality grade compared with the control, except for meat quality.Keywords: bentonite, Hanwoo steers, quality traits, yield traits.Desempenho, qualidade da carne e características de carcaça em novilhos Hanwoo em crescimento e engorda alimentados com bentonita RESUMO. Para avaliar os efeitos da suplementação com bentonita (0, 0,1 e 0,3%) sobre o desempenho de crescimento e características da carcaça e da carne, foram avaliados 36 novilhos Hanwoo, castrados, com sete meses de idade (peso inicial: 184 ± 5,2 kg) distribuídos nos três tratamentos. Utilizou-se um delineamento inteiramente casualizado com três repetições. A inclusão de uma dieta suplementada com bentonita teve influência no peso final, ganho de peso total e ganho médio diário. A suplementação com bentonita não teve efeito significativo na composição centesimal e na qualidade da carne. Para as características de carcaça, não houve diferenças significativas nas características de rendimento e de qualidade entre os tratamentos (mas não o peso da carcaça fria, nível de marmoreio e grau de qualidade). Concluiu-se que a suplementação com bentonita (0,1 e 0,3%) melhorou o desempenho de crescimento, peso de carcaça fria, nível de marmoreio e grau de qualidade em relação ao controle, com exceção da qualidade da carne.Palavras-chave: bentonita, novilho Hanwoo, características de qualidade, características de rendimento.

“…However, they were small, which justifies the use of the HCW in situations where there is no way to subject them to a cold environment. Since HCW and CCW are positively and highly significantly intercorrelated (P < 0.001) [ 35 , 36 ], it allows their use in the estimation of the chemical and physical components in carcasses.…”

Prediction of carcass composition through measurements in vivo and measurements of the carcass of growing Santa Inês sheep

In vivo and carcass measurements were evaluated to predict carcass physical and chemical composition and to list the measurements that best fit the prediction of the composition of growing Santa Inês sheep carcasses. Thirty-three animals were used to measure the loin eye area by ultrasound in vivo (LEAu) and in the carcass. We used 39 animals for biometric measurement in vivo and 42 sheep for morphometric measurement in the carcass. For the physical and chemical compositions of carcasses, dissection of the half left carcass was carried out in 42 animals. The data were submitted to Pearson’s correlation analysis and t test. Simple and multiple linear regressions were performed using a stepwise procedure. All correlations between in vivo measurements and the physical and chemical compositions of carcasses (in kg) were significant, except for LEAu. Biometric measurements and hot (HCW) and cold (CCW) carcass weights were considered as predictors of the carcasses’ physical and chemical compositions. Slaughter body weight (SBW) was the variable that most influenced the equations in the assessment of in vivo measurements and HCW and CCW most influenced the equations for measurements on carcasses. Biometric measurements of Santa Inês sheep can be used together with the SBW to estimate the physical and chemical compositions of carcasses, with emphasis on body compactness index, breast width, wither height, and croup height. The morphometric measurements can be used together with carcass weight to estimate the physical and chemical compositions of carcasses, with emphasis on croup width, carcass compactness index, croup perimeter, external and internal carcass lengths, chest width, and leg length and perimeter. The HCW can be used to predict the physical and chemical composition of carcasses without affecting the accuracy of the prediction model.

“…For instance, Cu-supplemented Angus were found with reduced back fat and reduced serum cholesterol level ( Engle et al, 2000 ). Pigs supplemented with Mn showed an increased marbling and decreased pH consistent with the correlation identified here ( Constantino et al, 2014 ). Furthermore, Se supplementation improved pork meat quality traits by increasing muscle pH ( Calvo et al, 2017 ).…”

Detection of Co-expressed Pathway Modules Associated With Mineral Concentration and Meat Quality in Nelore Cattle

et al. 2019

Meat quality is a complex trait that is influenced by genetic and environmental factors, which includes mineral concentration. However, the association between mineral concentration and meat quality, and the specific molecular pathways underlying this association, are not well explored. We therefore analyzed gene expression as measured with RNA-seq in Longissimus thoracis muscle of 194 Nelore steers for association with three meat quality traits (intramuscular fat, meat pH, and tenderness) and the concentration of 13 minerals (Ca, Cr, Co, Cu, Fe, K, Mg, Mn, Na, P, S, Se, and Zn). We identified seven sets of co-expressed genes (modules) associated with at least two traits, which indicates that common pathways influence these traits. From pathway analysis of module hub genes, we further found an over-representation for energy and protein metabolism (AMPK and mTOR signaling pathways) in addition to muscle growth, and protein turnover pathways. Among the identified hub genes FASN, ELOV5, and PDE3B are involved with lipid metabolism and were affected by previously identified eQTLs associated to fat deposition. The reported hub genes and over-represented pathways provide evidence of interplay among gene expression, mineral concentration, and meat quality traits. Future studies investigating the effect of different levels of mineral supplementation in the gene expression and meat quality traits could help us to elucidate the regulatory mechanism by which the genes/pathways are affected.
