Metrics details. The study was performed in the subtropical area of northeastern Mexico. Within each of the growing phases the four treatment diets were formulated to contain similar levels of crude protein, amino acids, and other nutrients. In a completely randomized design, birds were allocated to the four treatments with five replicates floor pens of 10 birds each. Diets for broilers are based on grains such as sorghum or corn plus soybean meal, which have been expensive in recent years.

DOI: This study was carried out to investigate the effect of feeding canola meal CM on broiler performance, carcass yield, body temperature and plasma triiodothyronine T 3 and tetraiodothyronine T 4 concentration under heat stress. One hundred and sixty day-old male broiler chicks were assigned in groups of 5 to 32 battery cages in two identical environmentally controlled chambers. Diets were isocaloric and isonitrogenous. The results revealed that body weight gain WG was depressed and feed conversion ratio FCR increased when CM was added to diets under thermo-neutral conditions.

Probiotics on performance, intestinal morphology and carcass characteristics of broiler chickens raised with lower or higher environmental challenge. Lilian F. Denise N. Lenita M. Stefani A.

This study examined strain, sex and slaughter weight effect on performance, meat quality and yield of broiler chicken. Ross strain had the highest feed intake Female broiler having heavier body weight Aboaca birds had the highest carcass yields for all slaughter weight than Anak and Ross.

The aim of this study was to investigate the effects of dietary supplementation with cinnamon oil on growth performance, behaviour, carcass traits and meat quality of broilers. One hundred and thirty-five Cobb day-old broiler chickens were randomly assigned into three equal treatment groups with three replicates pens of fifteen chickens each. The dietary treatments consisted of the basal diet as control C and basal diet supplemented with 0. On day 49, 5 birds from each pen 15 per treatment were slaughtered and the pectoralis major muscle samples were collected for meat quality evaluation.

This study was conducted to compare growth performance, carcass characteristics and meat quality of 4 breeds of local chicken. A total of 1-d-old chicks were distributed to 16 pens, with 4 treatments of breed, 4 replicates and 30 chicks per pen.

Performance and carcass characteristics of broiler chickens with different growth potential and submitted to heat stress. Mail Address. In order to evaluate the effects of broiler genotype and of heat exposure on performance, carcass characteristics, and protein and fat accretion, six hundred one-day-old male broilers were randomly assigned in a 2 x 3 factorial arrangement, according to the following factors: genetic group selected and non-selected broilers and pair-feeding scheme Ad 32 - reared under heat stress and fed ad libitum ; Ad 23 - reared at thermoneutrality and fed ad libitum ; Pf 23 - reared at thermoneutrality and pair fed with Ad 32 , with a total of six treatments with four replicates of 25 birds each. Independent of pair-feeding scheme, selected broilers showed better feed conversion, higher carcass yield, and lower abdominal fat deposition rate.

Original study 22 Jan The aim of this study was to determine the effect of herbal feed additive on growth performance, carcass characteristics, the chemical composition of breast muscles and selected meat quality parameters in broiler chickens. The experiment was performed on Ross chickens, which were randomly divided into six groups with six replicates per group. In experimental groups, dietary energy concentration was reduced by 0.

Growth performances and carcass characteristics of broiler chickens fed diets supplemented with graded levels of Canarium schweinfurthii Engl seed charcoal A or maize cob charcoal B were studied using a total of 3-week-old male chicks. Each of the diets was fed to ten individually birds caged in a completely randomized design. Results indicated that birds fed 0. The best growth performance was achieved with 0. Only the B 0. More than 0. It was concluded that under the conditions of this study, charcoal from maize cob or Canarium seeds could be used to improve growth performances and some carcass traits in broiler chickens.


The aim of this study was to compare the growth performance parameters, carcass quality, and meat traits in broiler chickens fed on diets containing legume​.

This study was conducted to compare growth performance, carcass characteristics and meat quality of 4 breeds of local chicken. A total of 1-d-old chicks were distributed to 16 pens, with 4 treatments of breed, 4 replicates and 30 chicks per pen. Three Korean local breeds of white-mini broiler, Hanhyupho, and Woorimatdag, and a breed of silky fowl were raised under identical rearing and feeding conditions for d, d, d, and d, respectively. Gain:feed of silky fowl was less than that of the 3 breeds of Korean local chicken. In conclusion, 4 local breeds of chicken have some unique features and seem to have more advantages, and this information can help consumers who prefer healthy and premium chicken meat. Meat is a nutrient-dense food and meat and meat products are important sources of wide range of nutrients. However, meat is not a homogeneous food group and the composition of meat varies by meat category Cosgrove et al.
