“…[10] working with half-blood Nelore/Simental young animals, found values for the cholesterol of 64mg/100g, results that are lower in comparison to the results in this paper. [11] obtained higher values for the cholesterol comparing to those found by [9,10] but lower than the results observed on our research. [12][13][14] they worked with castration in superpresences steers; precocious steers fed with protected fat and with pastureterminated animals, observed about 60mg /kg, 68mg /kg and 40mg/kg of total cholesterol in longissimus thoracis muscle, respectively.…”

The objective of this study was to propose an adaptation to the measurement methodology using enzymatic kits with raw meat and compare the efficiency in the quantification of total cholesterol in raw and freeze-dried meat, in order to optimize the execution of the analysis and the estimation of the results obtained. We used the longissimus thoracis and semitendinosus Nellore muscles which were acquired in a commercial slaughterhouse. They were ground with a food processor and separated; one of these parts was freeze-dried and the other was kept raw. The methodology purposed in our research (using freeze-dried meat), obtained better measures for cholesterol levels in both muscles. The total cholesterol measures for longissimus thoracis and semitendinosus with freeze-dried meat were 12% and 13% higher comparing to raw meat, respectively. The utilization of freeze-dried meat was more effective on the extraction and measurement of total cholesterol in both muscles.

“…Higher concentrations of myristic, palmitic, stearic, oleic and linoleic fatty acids in lamb meat were also found by Perez et al (2002), Demirel, Ozpinar, Nazli, and Keser (2006), Nuernberg, Fischer, Nuernberg, Ender, and Dannenberger (2008) and Leão et al (2011), who evaluated the effect of different types of diets on the fatty acid profile of lamb. Along with the observed decrease, the elevated concentration of oleic acid found in this study corroborates the literature regarding its presence in the composition of intramuscular fat in ruminants (Sañudo et al, 2000).…”

This study aimed to evaluate the effect of pearl millet silage ammoniated with urea on lamb carcass characteristics and meat quality. Thirty-two noncastrated crossbred lambs at 4-5 months of age, with an average initial body weight of 17.39 ± 2.16 kg, were distributed into four treatments in a randomized block experimental design with eight animals per treatment. Experimental diets were composed of pearl millet silage ammoniated with four levels of urea (0%, 2%, 4% and 6%, on dry matter basis (DM). Carcass conformation and fatness decreased linearly (p < 0.05). Except for the fat content, the proximate composition was not influenced (p < 0.05) by the diets. Meat lightness and yellowness increased linearly (p < 0.05). There was no effect of diets (p > 0.05) on cooking losses or shear force. The levels of oleic and erucic fatty acid levels in the meat decreased linearly (p < 0.05), whereas linoleic and eicosadienoic acids, polyunsaturated fatty acids, PUFA:SFA ratio and ω6 contents increased (p < 0.05). Pearl millet silage ammoniated with urea allows for the production of good-quality lamb meat, with greater concentrations of polyunsaturated fatty acids. However, lambs fed diets with pearl millet ammoniated with up to 6% lead to a reduction of carcass characteristics without significantly affecting loin-eye area possibly associated with low palatability of the additive used. The lower acceptance of the silages with higher levels of urea is due to the ammonia retention in the material is attributed to the ammonization process. Thus, in spite of the benefits on lamb meat quality, it is suggested that the use of this additive in the ammonization of tropical forages be carried out with care, in limits of up to 6%.

“…Para as variáveis rendimento de carcaça quente e rendimento de carcaça fria foram verificados valores superiores para o tratamento com 100% de capim-Tifton em relação aos demais tratamentos. As variações no rendimento de carcaça podem decorrer em função de fatores intrínsecos ao próprio animal (genótipo, sexo, peso, idade) e/ou extrínsecos (alimentação, manejo, tipo de jejum) (Pérez et al, 2002), porém deve-se destacar a isonomia entre as dietas estudadas. O RCQ e RCF observados no presente trabalho foram superiores aos encontrados por Parente et al (2009), que trabalhando com ovinos em confinamento alimentados com bagaço de caju desidratado e feno de leucena verificaram valores médios de RCQ de 40,9% e RCF de 39,7%.…”

As leguminosas forrageiras introduzidas no Nordeste apresentam elevado nível protéico e boa produtividade. Dentre elas, destacam-se a leucena (Leucaena leucocephala), e a gliricídia (Gliricidia sepium (Jacq.) Walp.), estas leguminosas arbóreas possuem crescimento rápido e enraizamento profundo, características que favorecem a tolerância durante prolongados períodos de seca. O estudo foi realizado com objetivo de avaliar os efeitos de dietas contendo diferentes níveis de feno de leucena (Leucaena leucocephala) e gliricídia (Gliricidia sepium (Jacq.) Walp.) em substituição do feno de capim-Tifton 85 sobre características quantitativas de carcaças de cordeiros Morada Nova mantidos em confinamento. Foram utilizados 20 cordeiros da raça Morada Nova, não-castrados, com peso vivo médio inicial de 16,36 ± 1,53 kg com aproximadamente 100 dias de idade. A distribuição experimental foi em delineamento inteiramente casualizado com cinco tratamentos e quatro repetições, sendo os tratamentos constituídos por uma dieta controle com 100% de feno de capim-Tifton 85 como volumoso e quatro dietas com 50% de feno de capim-Tifton 85 + 50% de feno de leucena; 100% de feno de leucena; 50% de feno de capim-Tifton 85 + 50% de feno de gliricídia e 100% de feno de gliricídia. Foram avaliados o peso corporal, peso corporal ao abate, peso da carcaça quente, rendimento da carcaça quente, peso da carcaça fria, rendimento da carcaça fria, rendimento biológico, pesos e rendimentos de cortes comerciais e medidas morfométricas de carcaça dos cordeiros. A utilização dos fenos de leucena e gliricídia na alimentação dos animais acarretou em diferenças entre os tratamentos para peso corporal ao abate, peso do corpo vazio, peso da carcaça quente, rendimento da carcaça quente, peso da carcaça fria e rendimento da carcaça fria, exceto no rendimento biológico, perda por jejum e perda por resfriamento de cordeiros. Observou-se diferenças para os pesos absolutos (kg) de meia-carcaça, peso de perna, paleta, lombo anterior, lombo posterior, costela, fraldinha e rendimentos (%) de lombo anterior, posterior e fraldinha. De acordo com o estudo, o feno de leucena pode substituir o de capim-Tifton 85 e o de gliricídia pode ser utilizado até o nível de 50% na alimentação dos ovinos sem prejudicar as características quantitativas de carcaça, além de consistirem em uma alternativa na alimentação de animais de corte em terminação.
