“…The moisture average (73.3%) were similar to the values observed by Prado et al (2008a) Kazama et al (2008) suggested that variation in moisture percentage occurs when there is variation in total lipids percentage. However, in this study, the total lipids percentage changes only from 1.29 to 1.47% among genetic groups.…”

“…However, there was no difference (P>0.05) between Canchin and Charolais × Caracu genetic groups and Caracu and Aberdeen Angus × Canchin genetic groups. Different values were verified by Kazama et al (2008) and Prado et al (2008a), who observed inferior values of n-3 for genetic group Angus × Canchin of 0.48%.…”

“…The mean percentage was 29.9%. Kazama et al (2008) and Rotta et al (2009b) showed that C16:0 percentage can be changed from 25% to 30% in the longissimus muscle of crossbred bulls finished in feedlot. Fatty acids C14:0 and C16:0 are considered hypercholesterolemic; they are responsible for the increase in quantity of lipoproteins of low density (LDL) that are responsible for heart disease.…”

This experiment was carried out to evaluate the carcass characteristics, chemical composition and fatty acid profile of the longissimus muscle of 32 young bulls from four genetic groups: Caracu; Canchin; Aberdeen Angus × Canchin; and Charolais × Caracu, finished in feedlot and slaughtered at 22 months old. Each group was composed of eight animals. There was no difference for moisture, ash, crude protein or total cholesterol between bulls from different genetic groups. However, total lipids percentage was higher for bulls from Caracu and Aberdeen Angus × Canchin and lower for Canchin and Charolais genetic groups. Polyunsaturated fattty acids and n-6 percentage was higher for Canchin and lower for Caracu, Aberdeen Angus × Canchin and Charolais genetic groups. Canchin and Charolais × Caracu genetic groups presented higher n-3 percentage than Caracu and Aberdeen Angus × Canchin. There was no difference for the n-6/n-3 ratio among the bulls from the four genetic groups

“…Much of the acid vacenic absorbed is converted into CLA in the adipose tissue of the animal cattle by the action of the enzyme Δ9 -"desaturase" (Griinari & Bauman, 1999;Bauman, 1999). Kazama et al (2008) raises a hypothesis that CLA produced by ruminal biohydrogenation of linoleic acid is an intermediate transient, while vacenic acid is accumulated in the rumen and it is available for absorption, an assertion based on the speed of the conversion rate of linoleic and α -linolenic acids in trans -vacenic acid that is faster than the transformation of trans -vacenic stearic acid (Izumi et al, 2002.…”

Profile of ingested fatty acids and in the duodenal digest of steers fed different diets

-It was evaluated in this study the effect of the type of the diet on duodenal flow of long-chain fatty acids in steers. The tested diets were the following: conventional (feedlot diet composed of 60% corn silage and 40% of concentrate); winter forage silage -rye grass (Lolium multiflorum, Lam); or tropical forage silage -association of millet (Pennisetum americanum, Leeke + alexander grass, Brachiaria plantaginea). Six Charolais × Nellore crossbred steers with cannulas in duodenum were used in a 3 × 3 double Latin square. Dry material intake was similar among the groups (mean of 4,037 g/day), but the intake of total fatty acids and saturated fatty acids were higher in the group fed tropical pasture silage. On the other hand, the animals which received the conventional diet consumed higher quantity of unsaturated fatty acids. Tropical pasture silage provided higher consumption of vacenic acid (C18:1 t-11) and the winter forage silage offered higher consumption of conjugated linoleic acid. The intake of omega-6 fatty acids was higher in the group fed conventional diet and for omega-3, intake was higher in the group fed tropical pasture diet. The total fatty acid flow in the duodenum was not affected by the diets, but in all treatments it was higher than the consumed one. The animals fed diet with concentrate show the greatest changes on the profile of fatty acids during the ruminal fermentation. Conventional diets provide the highest intake of unsaturated fatty acids and the highest availability of vacenic acid in the small intestine, but they do not increase the supply of intestinal conjugated linoleic acid.

“…Para bovinos estes parâmetros são de fundamental importância (Pacheco et al, 2005). Segundo Restle et al (1999), Costa et al (2002) e Kazama et al (2008), em bovinos, o peso e o rendimento da carcaça são medidas de interesse dos frigoríficos para avaliação do produto adquirido e dos custos operacionais, visto que carcaças com pesos diferentes demandam mesma mão-de-obra e mesmo tempo de processamento. Atualmente o peso de carcaça é a forma mais utilizada pelos frigoríficos.…”

Influência do peso vivo, da idade e do sexo sobre características de carcaças de equinos

et al. 2010

RESUMO -Com o objetivo de avaliar as características quantitativas de carcaças de equinos, classificaram-se 72 equinos sem raça definida segundo o peso vivo, a idade e o sexo. Foram determinados o peso de carcaça fria, a quebra ao resfriamento, o rendimento de carcaça, os pesos de dianteiro e traseiro e a relação músculo/ossos. O modelo estatístico foi o inteiramente casualizado, em esquema fatorial 2 × 3 × 3, com dois sexos, três faixas etárias e três faixas de peso vivo. A maior faixa de peso correspondeu a maior peso de carcaça, com média de 201,71 kg; e a maior relação músculo/osso, com 77,69%. A menor quebra ao resfriamento foi observada na menor faixa de peso, com 2,03%. A média para rendimento de carcaça foi de 51,20%, para dianteiro 54,86% e para traseiro 45,06%. Houve interação entre sexo e idade dos animais para a variável rendimento de carcaça, que foi maior nos machos jovens (até 8 anos) que nos mais velhos e nas fêmeas. Portanto, no abate de equinos, é recomendável priorizar animais jovens e mais pesados, por apresentarem maior quantidade de carne tipo exportação.Palavras-chave: análise quantitativa, carne equina, quebra ao resfriamento, rendimento de carcaça Influence of body weight, age and sex on characteristics of carcasses of equinesABSTRACT -With the objective of evaluating the quantitative characteristics of carcasses of equines, 72 undefined breed equines were classified by body weight, age and sex. It was determined cold carcass weight, cooling loss, carcass yield, front and back weight and muscle/bone ratio. The statistical model used was a completely randomized design in a 2 × 3 × 3 factorial scheme, with the two sexes, three age ranges and three ranges of body weights. The highest weight range corresponded to the highest carcass weight with average of 201.71 kg, and the highest muscle/bone ratio with 77.69%. The lowest cooling loss was observed in the lowest weight range, with 2.03%. The average for carcass yield was of 51.20%, for front and back, 54.86% and 45.06%, respectively. There was an interaction between sex and age of the animals for carcass yield variable, which was higher in young male equines (until 8 years of age) than in older animals and females. Therefore, it is suggest priorization of young and heavier animals for equine slaughter because they present higher amount of exportation-type meat.
