Ostrich (Struthio camellus) carcass yield and meat quality parameters
Provedor de dados: 89
Autores: Balog,A; Almeida Paz,ICL.
This article aimed at compiling recent studies on the main factors that influence ostrich meat quality and carcass yield. Few articles investigated the effect of subspecies, which generally are not even mentioned. There are important dietary effects, particularly those caused by dietary protein to energy ratio. Rigor mortis follow-up studies showed that there are no losses in meat quality when carcasses are hot-deboned. Age at slaughter influences some meat quality traits, such as tenderness and lipid content. Few effects of gender have been observed, and at the same age at slaughter, both male and female present the same meat quality traits.

Com o objetivo de determinar os melhores níveis nutricionais de cloro para codornas italianas destinadas à produção de carne (um a 49 dias de idade), foram utilizadas 384 codornas com um dia de idade, distribuídas em delineamento inteiramente casualizado, com seis tratamentos e oito repetições de oito aves por unidade experimental. Os níveis de cloro avaliados foram: 0,07; 0,12; 0,17; 0,22; 0,27 e 0,32%. Não foram observados efeitos significativos dos níveis de cloro das rações sobre todos os parâmetros avaliados. Considerando-se que os níveis de cloro não promoveram sinais de deficiência ou excesso que pudessem ser determinados por alterações no desempenho das codornas, pode-se recomendar que rações para codornas de corte de um a 49 dias de idade podem...

An experiment was conducted to evaluate the performance, bone densitometry and carcass yield of broilers chicks, using different levels of phytase enzyme. Nine hundred and sixty male one-day-old broiler chicks were used. The birds were distributed in a completely randomized experimental design, involving five treatments and six replications of 32 chicks each. The treatments consisted of a control diet for each phase, and four other diets were formulated adding growing levels of the phytase enzyme (250, 500, 750 and 1,000 FTU of phytase kg-1 feed). When adding the phytase enzyme, the nutritional matrix was valued to guarantee the same nutritional levels as the control diet. In general, the addition of phytase enzyme determined a linear decrease on the...

ABSTRACT A non-surgical sterilant (NSS) was used with the objective of assessing the zootechnical performance, carcass and meat quality, and hormone levels. 90 male piglets were selected with birthweights varying between 1.5kg to 2.0kg. The control group was constituted of 45 males castrated by the conventional surgical method, at the seventh day of age, and the treated group was constituted of 45 males castrated with NSS (active principle of zinc gluconate in the concentration of 26.2mg/mL associated to the dimethyl sulfoxide at 0.5%), with the application of the first dose on the seventh day of age and the second dose on the fourteenth day of age. The zootechnical assessments were carried out on the farm and consisted: weight gain in the periods per...

The aim of this study was to evaluate the effect of increasing levels of concentrate on the quantitative and qualitative carcass characteristics of feedlot ewes. Twenty-four crossbred ewes were randomly distributed in four treatments: (1) diet with 20%; (2) 40%; (3) 60%; and (4) 80% of concentrate. Animals were slaughtered when those receiving the diet with 80% of concentrate reached adult weight, at around 50kg LW. The data were analyzed by means of variance and regression analyses and correlations. The levels of concentrate increased live weight at slaughter linearly. Height at the withers and rump presented medium to high correlation (0.86). The correlation of loin eye area measured on the carcass and by ultrasound examination was 0.81, whereas for back...

The aim of this work was to evaluate the effect of broiler breeders' age and yeast wall (YW) levels on broilers' performance and macrophage activitys. The experiment consisted in a completely randomized design and a 2 X 5 factorial arrangement and two controls of two broiler breeders age (34 and 57 weeks of age) and five YW levels (zero, one, two, three or four kg of YW/ton of diet). They received sorghum diet compared to a control corn/soybean meal diet. The age of the broiler breeders influenced the performance, but did not affect macrophage activity. At 34 weeks age broiler breeders' progeny, all diets were similar considering the average weight. For 57 weeks age broiler breeders' progeny, at 21 days, only average weight of sorghum diet supplemented...

This study was carried out to evaluate the effects of different nutritional strategies at growing and finishing phases on carcass and meat characteristics from 24 crossbred steers predominatly Holstein, slaughtered at 15 months of age and with 395.00kg of body weight. At the growing phase, the animals were maintained on Brachiaria brizantha pasture with two levels of supplementation in amounts equivalent to 0.5 or 1.0% of body weight. Subsequently, the animals were finished in feedlot with diets composed of 50 or 80% of concentrate. The high level of the concentrate at the finishing phase increased significantly (P&lt;0.05) the hot carcass yield (50.16 vs. 48.62%). The lowest level of supplementation at the growing phase resulted in higher (P&lt;0.05)...

ABSTRACT: This study aimed to evaluate the effects of feed restriction on the carcass characteristics of castrated Canindé goat kids. A randomized block design was used, in which 21 goat kids with a body weight (BW) of 15.9±1.0kg were allocated to three levels of feed restriction: ad libitum, 20% and 40% restriction related to the ad libitum intake. The diet consisted of 55% forage (Tifton) and 45% concentrate. All animals were slaughtered when the kids fed ad libitum reached a BW of 25kg. After slaughter, the carcasses were chilled for 24 hours and subsequently measured. Kids fed ad libitum and subjected to 20% feed restriction showed similar morphometric carcass measurements, except for the chest circumference. Goat kids fed ad libitum exhibited greater...

ABSTRACT: This study evaluated the effects of millet and corn oil additions to sorghum-based diets on the performance, carcass yields and prime cuts (i.e., wings, breasts, thighs and drumsticks) and the relative weights of edible offal (i.e., gizzard, heart, and liver) of broiler chickens. A total of 684 Hubbard Flex chickens, including 342 broilers of each sex, were housed. The design was completely randomized, and the following diets were supplied: A) sorghum and soybean meal + soybean oil (control); B) sorghum and soybean meal + corn oil; and C) sorghum and soybean meal + millet and soybean oil. Six replicates with 38 birds each (19 males and 19 females) were evaluated regarding each experimental diet. At 14, 21, 35 and 42 days of age, the feed intake,...

One performance experiment and another metabolism experiment were conducted simultaneously with broilers from 22 to 35 days of age, evaluating five diets in six replicates. The control diet, without phytase, contained 19% of crude protein (CP); 0.412% of available phosphorus (aP) and 0.824% of calcium (Ca). The other diets were supplemented with phytase and were formulated with 0.262% of aP and 0.524% of Ca, with the CP level ranging from 19 to 16%. In the performance assay, 750 birds were used, in which were evaluated the performance, the tibia ash content and yields of carcass, cuts, and abdominal fat at 35 days of age. The metabolism assay was conducted with 90 birds, evaluating the apparent metabolizable energy corrected by the nitrogen balance; the...
