This study examined the effects of supplementation of dietary sodium selenite and sodium enriched alga Chlorella on growth performance, selenium concentration in breast meat and excreta, activity of glutathione peroxidase in meat, and oxidative stability of meat in broilers. Sexed broiler cockerels Ross 308 were allotted to 3 dietary treatments, each comprising 100 chickens. The basal diet was ...

The objective of the study was to determine the effect of Acacia karroo supplementation on growth, ultimate pH, colour and cooking losses of meat from indigenous Xhosa lop-eared goats. Eighteen castrated 4-month-old kids were used in the study until slaughter. The kids were subdivided in two treatment groups A. karroo supplemented (AK) and non-supplemented (NS). The supplemented goats were give...

This study was conducted to investigate the effect of feeding method (wet and dry) on the performance of meat quail chicks. This experiment was carried out with 160 one days old quail chicks in completely randomized design, 2 treatments included 4 replicates (20 quail chicks in each replicate) and conducted for a 35 day period. Measured traits, were included performance parameters, carcass char...

The aim was to verify organic system effect on carcass and meat quality of beefs. Twelve carcasses derived from Limousine x Red Pied beef, reared in the San Rossore Park (Tuscany) and slaughtered at 24 months of age, were used. After 24h post-mortem, carcasses were evaluated according to UE classification grid: on right half carcasses several measurements were taken and carcass compacteness was...

In order to identify genes controlling meat quality and carcass traits we are aiming to combine two approaches: (1) the QTL analysis (2) and expression profiling. Here results of QTL analyses in different porcine resource populations and current attempts to identify functional candidate genes for meat quality traits are reviewed and own efforts are presented: A QTL scan for meat quality and car...

One hundred thirty-one pigs representing seven different breed groups (Minnesota No. 1 [M], Pietrain [P], Yorkshire [Y], and crosses PY, P[PY], P[NP], and P[YP]P) and three halothane gene genotypes (NN, Nn, and nn) were tested for breed, sex, and halothane gene (HAL) effects on growth and carcass performance. Breed effects were significant for all traits measured. Sex effect was significant for...

An experiment was performed to investigate the effect of animal vs. vegetable protein sources in the diet of laying hens on the development of hen performance. A diet containing protein sources of only vegetable origin was compared with 4 diets, each containing 1 of 4 processed animal proteins (PAP). Two PAP (Daka-58 and Sonac-60) were classified as meat meals, and the remaining 2 (Daka-40 and ...

In the modern broiler industry, solutions are still being sought to improve conditions or eliminate problems related to issues such as animal welfare, health, and meat quality brought by intensive production systems. Therefore, this experiment was conducted to study effects of perching on growth performance, carcass characteristics, and footpad lesions (FPLs) in broiler chickens. A total of 300...

In Niger, the growth in local demand for milk and meat makes it necessary to consider genetic improvement of the indigenous cattle. At the Toukounous breeding station, the Azawak zebu has undergone over 50 years of line breeding for milk and meat production traits. To understand the adoption potential of improved Azawak sires in Niger, this study proposes to estimate the values that cattle keep...
