Two experiments were designed to study the growth and carcass characteristics and the effects of system of management on the Japanese quail. In the first experiment, 138 birds raised to 8 weeks of are were used to study the growth and carcass characteristics of quails. Day old weight averaged 8.67±0.75y while body weights at 4 and 8 weeks of age were 130.38±21.81g and 175.08±21.23g respectively. Feed conversion rate to 8 weeks was 6.42 with each bird consuming 1067.68g feed. No significant sex differences (P>0.05) were observed in the average yield of parts although the males had slightly higher dressed and eviscerated weights and percent wing, back and neck than females. Dressed weight was 93.55% on the average while eviscerated weight was 68.61%. the carcass contained 74.20% moisture, 69.63%CP and 26.5% fat. In the second experiment, 120 birds were used to test the effect of management system (floor vs. cage) on growth and carcass characteristic of the quail. Although floor rearing had a slight advantage over cage rearing in terms of weight gain, feed conversion ratio and carcass yield, the differences were not significant (P>0.05).

The aim of this work was to examine the possibility of using different poultry breeds for meat production in extensive systems, concerning their slaughter traits. Total of 200 birds of two genotypes were used in this trial: fast-growing hybrid Ross 308 and pure breed White Rock. Chicks were raised indoors until the age of 4 weeks and subsequently they were enabled to access the range. The trial lasted for 13 weeks. At the end of the trial, 10 male and 10 female chicks per breed were sacrificed for the evaluation of slaughter traits - dressing percentage, yield and share of carcass parts. It was established that both genotype and sex significantly affected carcass traits while genotype affected production traits. Chickens of the Ross 308 hybrid had higher body weights, better feed conversion ratio and higher mortality rate. Chickens of the Ross 308 hybrid had dressing percentage compared to the White Rock breed, while the male chickens had higher dressing percentage compared to the female ones. Chickens of the Ross 308 hybrid had a significantly larger weight and share of breast meat, whereas those of the White Rock breed had a larger share of drumsticks and thighs. A significant influence of the genotype was determined on the amount of abdominal fat in the carcass. Chickens of the White Rock breed had a significantly lower fat content compared to the Ross 308 hybrid, which essentially makes them the genotype which is more suitable for the extensive fattening longer than 10 weeks.

An experiment was conducted to compare the productivity and profitability of commercial broiler, cockerel and cross-bred (F1 RIR ? × Fayoumi ?) chicks up to target body weights of 850, 1000 and 1250g. Two hundred sixteen birds of 3 genotypes each of 72 birds having 18 chicks in each replication were considered. Commercial broiler starter diet was fed to experimental birds ad libitum. Similar care and management were provided to birds of all treatment groups. Commercial broilers attained the target weights of 850, 1000 and 1250g at the age of 21, 24 and 28 days respectively whereas cockerels attained weights close to those targets at 56, 63 and 74 days respectively and in the case of cross-breds, the days were 63, 77 and 90 for those target weights respectively. Feed conversion ratio (FCR) was best in broilers, followed by cockerels and cross-bred chicks respectively. The highest mortality (8.3%) was found in cross-bred group when reared up to target weight of 1250g. The mortality of broiler was 1.4% and no bird was died in cockerel group. Broiler was most profitable (21.11 Tk/kg live bird) at the target weight of 1250g whereas profit from cockerel varied little (21.78, 21.07 and 21.63 Tk/kg live bird against the target weights of 850, 1000 and 1250g respectively) amoung target weights. Therefore, appropriate weight to market these birds was at 850g to minimize the risk of diseases and other management works. Marketing of cross-bred chicks was most profitable (8.43 Tk/kg live bird) at 850g target weight and loss was incurred when rearing was continued up to 1250g. On the basis of results of productivity, it was concluded that commercial broiler, cockerel and cross-bred chicks could be reared upto 28, 56 and 63 days respectively to reach target weights close to 1250, 850 and 850g respectively to obtain maximum profit.?

Growth performance and carcass characteristics of capons (castrated cockerels) from three breeds/strains locally presented in Slovenia and Austria were investigated. Growth and feed consumption data were collected for a 156-d and 199-d period, when randomly chosen animals were slaughtered and their carcasses dissected. The feed conversion rate in barred Prelux, Sulmtaler and Styrian capons for the whole growing period was 6.24 kg, 6.32 kg and 7.53 kg, respectively. Average body weight in barred Prelux and Styrian capons increased only in the first 156 days of age, but not further on. Cumulative mortality rate in Sulmtaler capons was 19.05 % and was 2.7- to 4.4-fold higher as compared with Styrian and barred Prelux capons (6.90 % and 4.31 % respectively). Sulmtaler capons had the lowest abdominal fat content. Barred Prelux capons, as compared to capons from other two breeds were characterized by higher pre-slaughter weight, higher carcass weight and higher dressing out percentages. This indicates that the layer type barred Prelux cockerels have a potential to be as capons put to profitable use.

The objective of the study was to evaluate the effects of expanded diets on growth performance, meat quality, and carcass characteristics in finishing pigs. A total of 80 finishing pigs [(Landrace × Yorkshire) × Duroc] were randomly allotted to two dietary treatments: 1) unexpanded corn-soybean meal diets; 2) expanded corn-soybean meal diets. Each treatment consisted of ten replicate pens with four pigs (2 gilts and 2 barrows) per pen. There were no differences in daily feed intake and daily gain throughout the experiment (P less than 0.05). However, expanded diets decreased feed conversion ratio compared with unexpanded diets (P less than 0.05). Expanded diets had no effect on carcass characteristics and meat quality with the exception of increased sensory evaluation (color) of meat compared with unexpanded diets (P less than 0.05). In conclusion, expanded diets can improve feed conversion ratio but have no effect on daily gain and daily feed intake and sensory evaluation of meat color.

Dietary Copper

This study was conducted to investigate the effect of dietary copper and probiotic supplementation on growth performance and carcass characteristics of broiler Chickens. A total of 180-day old marshal broiler chicks of mixed sex were randomly allotted to six treatment groups of 30 birds each. The Treatments were divided into three replicates of ten birds each; starter and finisher diets were formulated and fed for a period of fifty-six days. The dietary treatments were subjected to completely randomized design experimental layout which was made up of probiotic (0 and 500ppm) and copper (0, 125 and 250mg).The chicks were fed the broiler starter diet for the first 28 days and broiler finisher for the last 28 days. Treatment effect on broiler body weight, feed intake and feed conversion ratio were determined on a weekly basis. Data obtained were analyzed using analysis of variance (ANOVA) and, Duncan's Multiple Range Test was used to separate significant means. Dietary supplementation of copper and probiotic had no significant (P> 0.05) effect on final weight (FW), daily weight gain (DWG), feed intake (FI), and feed conversion ratio (FCR) at the starter phase of the experiment. However, at finisher phase, inclusion of probiotic resulted in higher significant (P < 0.05) values for FW (2214.12g/b) DWG (60.22g/b/d), FI (159.02g/b/d), and FCR (2.64). The carcass yields of the broilers were significantly (P< 0.05) influenced by copper and probiotic supplementations. However, lower value (1.07%) was obtained for abdominal fat in broilers fed 250mg Cu/kg supplemented diet. The study concluded that supplementation of copper and probiotics resulted in improved growth performance and carcass yield of broiler chickens.

Egg Weight

The aim of this study was to determine the effect of the genetic groups (three of local quails different with feather color, which are white, black and brown) and the egg weight (three classes of eggs are heavy, medium and light) and the interaction between them on productive performance during the growth phase (0-6 weeks of age). Eggs were individually weighed and graded into three groups: heavy (11.5-12.4g), medium (10.5-11.4g), and light (9.5-10.4g) inside each genetic group. The results of the statistical analysis showed a significant effect (p?0.05) of the genetic group (feather color), egg weight and their interaction on the productive performance during the total breeding period.The brown birds had significantly higher values of body weight, weight gain, carcass characteristics and better feed conversion ratio in all analyzed weeks. The birds which hatched from heavy eggs showed higher value of body weight, weight gain, carcass characteristics, feed consumption and better feed conversion ratio. Brown birds which hatched from heavy eggs had higher value of body weight, weight gain and carcass characteristics, while brown birds which hatched from medium eggs had better feed conversion ratio. We can therefore consider brown quail as the best for fattening purposes

Slight Advantage

Young cattle were fed whole or cracked wheat with 20% lucerne hay, either ad lib or at a medium level, restricted to approximately 2.3% of fasted liveweight. Over 70 days, animals fed ad lib consumed 3.2 and 2.7% of their mean fasted liveweight on whole and cracked wheat respectively, and weight gains on the ad lib diet were higher than those on the medium feeding level. Cracked wheat gave 32% higher liveweight gains than whole wheat when feeding was restricted to 2.3% of fasted liveweight. However, animals offered whole wheat ad lib consumed 24% more feed, and attained the same rate of gain as those on cracked wheat. Feed conversion ratios were 7.0 and 8.8 for cracked and whole wheat, respectively. It would be economical to crack wheat only if the cost of double handling and processing 6.6 t of wheat was less than the cost of an extra 2.0 t of whole wheat. Animals fed lupins for 42 days did not consume as much as those fed wheat, but gains were only slightly lower. Lupins may be better suited to increasing the protein content of mixed rations. Only when animals were fed ad lib was there some slight advantage in adding urea to wheat rations. When whole wheat and whole oats were fed at the same restricted level, liveweight gains were higher on oats and feed conversion ratio was lower.
