Recently ,there is an incrase interest in fattening camals in Iran .This trial aimed to define the influence of dietary energy and protein levels on performance and carcass quality of camels in khorasan province.For 80 days, nine diets with three metaboliseble energy 10.9, 8.8 or 7.6 MJ /kg DM and three crude protein levels 140, 120, or 100 g/kg DM were offerd ad lib to thirty six camels (mean initial weight 183 kg ± 7.7) , where each treatment were randomly allocated to four animals, that were housed individually. Food intakes were recorded daily. Throughout the trial , all animals were weighed at fortnightly intervals. At the end of the project ,two animals from each treatment were slaughtered and carcass quality were determined. Data were analysed as a 3x3 factorial Anova, with energy and protein were the main effects.

The effects of sex and age of castration of males on growth rate, feed efficiency and carcass characteristics in bacon type swine were measured using 16 pigs each as gilts, entire boars, and boars castrated at birth, 6, 12, 16, and 20 weeks of age. Castration at 20 weeks was too late since some pigs reached 200 pounds live weight before that age. Boars consumed less feed daily than barrows and gilts, were thinner in loin fat, and yielded a higher percentage of shoulder than gilts. The carcasses of boars and gilts were longer, had less fat covering over the shoulder and back, a larger area of loin, and a higher iodine number than those castrated late. Acceptability tests showed that sex or age of castration did not affect the flavour, odour, or tenderness of the meat.Purebred breeders can delay castration for better selection of boars without any serious effect on growth, physical carcass characteristics, and feed requirements. Although the market discriminates against boars, it appears questionable whether castration is necessary when boars are slaughtered at 200 pounds before they reach the age of 150 days.

Fattening of farm animals is a way of increasing the rate of meat deposit after maturity. Its effectiveness depends on genetic status of the animal and the diet fed to the animal. In this study, performance and carcass evaluation of balami rams finished on diets with varying energy levels were carried. Forty-eight rams of Balami breed, weighing 20.75±1.50- 22.50±1.91kg were randomly alloted to four dietary energy levels (EL): 2.20Mcal/kg (EL ), I 2.40 Mcal/kg ((EL ), 2.60 Mcal/kg ((EL ) and 2.80 Mcal/kg ((EL ) for 90 days. The feed II III IV intake and daily weight gain of the animals in each treatment were determined and the average recorded. Three Balami rams were randomly selected from each treatment and sacrificed to determine the dressing percentage (DP), carcass weight (CW), fat deposit (FD) and meat yield (MY). Data were analysed using descriptive statistics and ANOVA at á . The 0.05 FBW (kg) of Balami rams in group EL , EL , EL and EL were 41.88.6±1.97, 42.12±1.84, I II III IV 46.13±1.65 and 52.24±2.50 while the FCR of animals on treatments EL (5.3±0.28) and EL I II (5.2±0.26) were higher than EL (4.7±0.82) and EL (4.0±0.65). The DP (%) were 54.9, III IV 54.9, 55.8 and 56.1, the FD (%) were 9.00,9.59,8.92 and 11.46 and the MY (%) were 75.2, 74.7, 75.5 and 72.0 for rams on EL , EL , EL and EL The results indicate that, increasing I II III IV. levels of energy improved growth performance and carcass quality of Balami rams. Therefore, higher level of dietary energy (2.80 Mcal/kgDM and 14% CP) could be suggested for optimizing growth performance and meat quality of Balami ram under fattening condition.

Commercial source, medium-type male poults were either placed in floor pens with food and water within 6 h after hatching or delayed a subsequent 24 h. Starting feed offered in each case was either of a normal (28% crude protein and 2,850 kcal ME/kg) or high (30% and 3,040 kcal) nutrient concentration. During the initial 2 wk, birds that had been fasted gained less weight but had a better feed conversion than those placed early. Poults which received a ration having a high nutrient concentration gained more weight and had a better feed conversion than those offered the normal diet. Mortality at this time was greater with birds subjected to a fast than those placed early. Having access to the higher nutrient concentration ration led to a greater mortaility than if the normal diet was employed. Body weight differences established during the first 2 wk remained throughout the experiment. Feed conversions of rations common to all groups during the subsequent 2- to 6-, 6-to 10- and 10- to 14-wk periods were not influenced by the early treatments after 6 wk of age. Slaughter at 14 wk did not reveal any differences in apparent carcass yield, conformation or finish grade. Degree of fleshing was reduced when poults were subjected to a post-hatch fast and partially improved when the high nutrient starting diet was fed. Effects of fasting and early nutrition on mortality and carcass changes are explained in terms of biochemical events occurring with the neonate.

Gracilaria sp is as eaweed with carbohydrate-rich wastes. Its symbiont, Brotia sp,is rich in calcium and protein. The effects of Gracilaria’s wastes (GW) as formulated feed supplement on carcass characteristics and production efficiency of local Indonesian ducks. Data were collected from 120 ducks fed either a basal dietor a fermented Gracilaria’s wastes supplemented diet (FGW). Treatment levels of FGW were 10%, 12.5%, and 15%. The highest level of meat antioxidant status was reached at 15% FGW, while the optimum level of FGW for decreasing the fat content was 12.5%. The best reduction in meat fat mass was at 15% FGW. Further more, duck feed with FGW resulted in lower average and normalized costs and increased income than observed with the basal diet. Thus, GW as a feed supplement effectively ameliorated the productivity and carcass quality of indigenous Indonesian ducks.
