“…The present study also obtained results similar to those of Lopes et al (2012) and Pitombo et al (2013), the first working with feedlot Nellore bulls, obtained moisture, CP and ash values of 74.2%, 21.9% and 1.0%, respectively. In turn, Pitombo et al (2013) worked with Nellore X Guzerá bulls and reported values of moisture, EE and ash of 75.34%, 1.44% and 1.04%, respectively.…”

ResumoO presente trabalho teve como objetivo, avaliar o efeito da Brachiaria spp. cv. Mulato II (Convert) sobre o desempenho, qualidade de carne e características de carcaça de novilhos Nelore castrados, na fase de recria e terminação, em sistema de pastejo rotacionado em comparação com a Brachiaria brizantha cv. Marandu, nas mesmas condições. A área experimental era composta por 40 hectares, divididos em dois tratamentos: Marandu e Convert, com 20 hectares cada. Cada tratamento possuía quatro repetições e cada repetição era um módulo composto por cinco piquetes de um hectare cada. Os animais foram manejados de acordo com a oferta de matéria seca de lâminas foliares (6,19% do peso vivo), em pastejo rotativo, com 7 dias de ocupação e 28 dias de descanso. Foram utilizados 10 animais em cada repetição (testers), além de animais reguladores, quando necessário. Para análises de desempenho, foram utilizados os 10 animais de cada repetição, enquanto para análises de carcaça e carne utilizouse seis animais por repetição. Foram avaliadas caracteristicas de produção e bromatológicas das duas gramíneas. O delineamento experimental foi inteiramente casualisado com dois tratamentos e quatro repetições, os dados foram submetidos à análise de variância utilizando o programa estátistico R. Os animais alimentados em pastagens estabelecidas com capim Convert foram superiores em relação aos alimentados em pastagens estabelecidas com capim Marandu, tendo maior ganho médio diário durante o período experimental (0,682 kg x 0,605 kg), peso ao abate (470,45 kg x 451,43 kg), peso de carcaça quente (239,93 kg x 232,36 kg). O trabalho também mostrou a possibilidade de terminação de novilhos castrados jovens (até 30 meses) e com a espessura de gordura subcutânea exigida pela indústria (3 mm) em ambas pastagens utilizadas.

Mulato II (Convert) on performance, meat quality and carcass characteristics of castrated Nellore steers in the growing and finishing phases, in rotational grazing system, compared to Brachiaria brizantha cv. Marandu, under the same conditions. The experimental area was divided into two treatments: Marandu and Convert with 20 hectares each, splited in four replications per treatment, composed of five paddocks of one hectare each. Animals were managed based on the availability of leaf blade dry matter (6.19% body weight) in rotational grazing with 7 days of occupation and 28 days of rest. Ten animals were used in each replicate (testers), as well as regulatory animals whenever necessary.

“…According to Daley, Abbott, Doyle, Nader, and Larson (2010), in a healthy diet, a satisfactory ratio should be approximately 1-to 4-fold more n-6 fatty acids than n-3 fatty acids. In the present study, the mean was 2.06 in the meat, which was an appropriate balance, because the excessive consumption of n-6 fatty acids can lead to the development of some degenerative diseases, such as cancer, diabetes, and arthritis (Lopes et al, 2012).…”

Agriculture byproducts plays an important part in the diet of ruminant animals and consequently on food chain and has implications for the composition and quality of the livestock products (milk, meat, and eggs) that people consume. Feeding tannin to steers increases the amount of unsaturated fatty acids and meat tenderness, with a concomitant reduction on saturated fatty acids and the atherogenicity index in meat. Thus, we recommend adding tannin to steer diets to reduce the risk factors for cardiovascular diseases in red meat for human consumption.

“…Oleic acid is usually the fatty acid found in largest quantity, and it features the ability to elevate blood high-density lipoprotein (HDL) levels (LOPES et al, 2012). On the other hand, among the classes of fatty acids present in the meat, only the sum of SFA was affected by the dietary regime.…”

This study aimed to evaluate the effect of pre-and post-calving feed restriction on quantitative characteristics and lipid profile of meat from Morada Nova sheep. Twenty-four male lambs from single births only, with an initial weight of 10.0 ± 3.07 kg and at four months of age, were distributed in a randomized complete design, into three groups: pre-calving restriction (R-PRE; n=8) post-calving restriction (R-POS; n=8), and ad libitum feeding (ADLI; n=8). To make up the experimental treatments, the feeding regime applied previously on the sheep in the last third of pregnancy was considered. Treatments ADLI and R-POS were composed of lambs born from ewes fed ad libitum in the last third of pregnancy. Treatment R-PRE consisted of lambs born from ewes subjected to feed restriction in the last third of pregnancy at 60% of the recommended requirements for the group of ewes feeding ad libitum. For the lambs from treatments ADLI and R-PRE, the diet was supplied allowing 20% of the total supplied as refusals. For the animals from R-POS, a 30% restriction was imposed in relation to the animals feeding ad libitum. Animals were slaughtered with an average live weight of 25 kg. Afterwards, carcasses were chilled at 4 ºC for 24 h. Meat quality measurements were taken on the right side of each carcass; pH was determined immediately after slaughter and then again after chilling. Samples of the longissimus dorsi muscle were collected and frozen at -20 ºC. Moisture, ash, protein, total lipids, water-holding capacity, and cooking loss were determined in the meat samples, which were then subjected to the shear-force test. The sensory analysis was determined by the hedonic-scale test, in which sensory parameters of tenderness, juiciness, flavor, aroma, and overall acceptability and fatty acid profile were evaluated. There was a feed-restriction effect on protein, lipids, and water-holding capacity (P<0.05). Meat sensory attributes were not influenced by the nutritional regimes (P>0.05). Saturated fatty acid contents were affected by the treatments (P<0.05); however, there was no effect of nutritional regimes on mono-or polyunsaturated fatty acids (P>0.05). Feed restriction does not compromise the physicochemical or sensory quality of Morada Nova lambs meat, but rather provides a meat product of good acceptance. ResumoObjetivou-se avaliar o efeito da restrição alimentar pré e pós-natal sobre características qualitativas e do perfil lipídico da carne de ovinos da raça Morada Nova. Vinte e quatro cordeiros foram usados, machos, somente de parto simples, peso inicial 10,0 ± 3,07 kg e quatro meses de idade, distribuídos num delineamento inteiramente casualizado, em três grupos: restrição pré-natal (R-PRE; n=8) e pós-natal (R-POS; n=8), e ad libitum (ADLI; n=8). Para composição dos tratamentos experimentais foi considerado o manejo alimentar aplicado anteriormente nas ovelhas no terço final de gestação. Os tratamentos ADLI e R-POS foram formados por cordeiros nascidos de ovelhas alimentadas ad libitum no terço final da gestação....
