“…The variable SBW is susceptible to external influences [ 3 ]. However, it is a performance and fattening indicator [ 17 ], and therefore, as the slaughter weight was not fixed, SBW showed a high variation ( Table 1 ). In this sense, a diversified database is desirable for a better accuracy [ 18 ].…”

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

et al. 2021

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.

“…The high biomass production per unit area and nutritional value of herbage, coupled with the low production cost, contribute to these results [4]. The better use of herbage produced in pasture-based systems influences the feeding behavior of animals, allowing for increased nutrient intake [5].…”

Biometric measurements of Santa Inês meat sheep reared on Brachiaria brizantha pastures in Northeast Brazil

et al. 2019

This study was undertaken to examine biometric measurements during the growth phase of male and female Santa Inês sheep reared in Brachiaria brizantha pastures in northeastern Brazil. The experiment involved 24 castrated males and 24 females at an initial age of 90 days, with an average body weight of 19.04 ± 0.96 kg. Treatments consisted of the effect of four cultivars (Marandu, Xaraés, Piatã and Paiaguás) and two sexes. Six animals were used per treatment, in a randomized-block experimental design. The following characteristics were evaluated: abdominal circumference (AC), body condition score (BCS), body length (BL), body weight (BW), body capacity 1 (BC 1 ), body capacity 2 (BC 2 ), chest width (CW), heart girth (HG), leg circumference (LC), leg length (LL), rump height (RH), rump width (RW) and withers height (WH). Data were subjected to descriptive analysis, Pearson’s correlation, ANOVA and Tukey’s, Kruskal Wallis and Mann-Whitney tests. Univariate and multiple regressions were applied to estimate BW with a maximum error level of 5%. Significant differences were observed for the biometric measurements between sexes and cultivars (p<0.05). Body weight was highly correlated (>70%) with AC, WH, CG, RW, BC 1 and BC 2 . The male sheep grazed on cultivars Piatã showed the best values for BW (40.43 kg), HG, RW, WH, LL, LC (102.46; 20.8; 65.23; 60.44; 42.54 cm respectively) and BC 1 (4.25 kg/cm). Females grazed on cultivar Marandu had higher values for RW, CW, LL (17.26; 20.1; 75.98 cm respectively), BC 1 (6.03 kg/cm) and BC 2 (0.422 kg/cm). The equations that best estimated live weight were BC 1 and HG. In male and female Santa Inês sheep, biometric parameters grow differently depending on the cultivar where they are grazed during the growth phase. Cultivars Marandu and Piatã are the most recommended for sheep production, as they provided the best performance and body development in those animals.

“…Aliando a alta produção de biomassa por unidade área, o valor nutritivo da forrageira, e baixo custo de produção tem se tornando interessante ao produtor (MELO et al, 2016). O melhor aproveitamento da forragem produzida no pasto influência no comportamento alimentar dos animais, gerando uma maior ingestão de nutrientes (YILDIRIM et al, 2017).…”

Esta revisão objetiva analisar a influência dietética na saúde animal e seus efeitos na qualidade da carne e características de caraça, bem como os benefícios do consumo da carne ovina para a saúde humana. Realizou-se buscas de artigos publicados entre o período de 2000 e 2023 nas principais bases científicas em que o tema visasse a relevância da ovinocultura aliada a nutrição animal e manejo. Embora a produção de ovinos ocorra em todo o Brasil, ainda não é explorada de forma eficiente, e o consumo de carne ovina ainda é associado a ocasiões especiais, por isso, deve-se entender a percepção dos consumidores quanto a esse produto para aumentar a sua comercialização. A nutrição é um dos principais fatores que influencia na qualidade da carne, e o uso de alternativos naturais como óleos essenciais e extratos vegetais, que melhoram a cor, o aroma e garante maior tempo de prateleira, vem aumentando. Além disso, o uso de fontes lipídicas nas dietas de pequenos ruminantes melhora o perfil lipídico dos produtos, diminuindo a quantidade de ácidos graxos saturados e aumentando o teor de ácidos graxos monoinsaturados e poliinsaturados, que estão associados à prevenção de vários tipos de câncer e doenças cardíacas, melhorando também a imunidade. Os consumidores estão cada vez mais preocupados com a saúde e mais exigentes quanto à qualidade dos alimentos, assim, a indústria da carne deve-se atentar à percepção e preferências dos consumidores, a fim de suprir as demandas do mercado.
