In order to investigate the COMPENSATORY GROWTH, comparison of carcass characteristics and feed intake in Atabay lambs, an experiment was conducted using 21 male lambs. Lambs of 5-6 months with the average of 35±5kg were divided to finishing treatments (first treatment), 30 (2nd treatment) and 60 days restriction groups (3rdtreatment). At the end of the experiment 4 lambs from each treatment were slaughtered for carcass analysis. The differences in characteristics of skin, head and leg, neck, flank+brisket, shoulder, chest and ribs, feet, back, hot carcass, cold carcass, bone carcass, hearts, kidney, lung, liver and fat-taile weights between the treatments was significant (p< 0.05). The result showed no significant differences in characteristics including full and empty gastrointestinal tract, tallow, back bone fat depth, fat carcass, back muscle carcass section and carcass length (p> 0.05). Feed conversion coefficient restricted treatments after the period of restriction compared with control treatment was decreased (2ndtreatment 12.18 and 5.98 - 3rdtreatment 4.08). Daily gain increasing between the treatments in the end period was not significant (p>0.05). Therefore, the 30 days restriction treatment was preferred for optimum feeding, saving in feed consumption and carcass with less fatness.  

Introduction & Objective: COMPENSATORY GROWTH is a phase of rapid GROWTH following feed restriction in such critical situations which it is observed in cold water and warm water fishes. Response to starvation and refeeding this includes eating more fish, feed efficiency and GROWTH factors can be improved. Therefore, this study was designed to investigate the effect of starvation and COMPENSATORY GROWTH on GROWTH and survival of rainbow trout was conducted. Materials and Methods: This experiment was conducted for 8 weeks in four Groups and three replications: Group 1: 8 weeks full feeding, Group 2: One week starvation+a week feeding, Group 3: two weeks starvation+two weeks feeding, Group 4: three weeks starvation+three weeks of feeding. 240 fingerlings rainbow trout with an average initial weight 3.81±0.46 g, and the average initial length of 5.4±0.67 cm in 12 breeding tank with 20 fish per tank with a capacity of 50 liters completely randomized design and distribution of water for 8 weeks were maintained under the same conditions in terms of environmental conditions. Results: The results showed that there was a significant differences between groups in GROWTH factors of rainbow trout fingerlings (P<0.05). As fingerlings grow fed diet with starvation and COMPENSATORY GROWTH were compared with other groups. However, no significant difference in survival rates between groups.Conclusion: Results showed a reduction in starvation and COMPENSATORY GROWTH of rainbow trout fingerlings has not been able to offset the slowdown.

One of the major problems in aquaculture need to achieve a balance between GROWTH rate and optimal use of fish meal is provided. Successful breeding fish (such as kutum) to the ability to access food, nutrition and health could depend on to grow, especially in the larval stage guarantee.A COMPENSATORY GROWTH phase of rapid GROWTH following feed restriction in effect in such critical situations is what a lot of cellar and what has hydrothermal. This experiment for 6 weeks in the summer of 2009 and in Center for cultural and breeding of bony fish Syjuval, Bandar Turkman in Golestan province was conducted. Given the importance of factors physico chemical water and their impact on nutrition and ultimately the GROWTH of fish, these factors all the time growing precisely control was so that the amount of dissolved oxygen against ppm 7.09±0.06, the temperature equal to 24.61±0.2 and pH during the test 7.98±0.01 was measured. Kutum fry during the experiment with food that has SFK: moisture 8.7%, Ash 11.2%, protein 32% fat and 10.5% was fed. Experiments in four treatments and three replications following were: Treatment A: One week starvation+a week feeding, treatment B: two-week starvation+two weeks feeding, treatment C: three-week starvation+three weeks of feeding, treatment D: 6 weeks feeding complete. Feeding rate of 10 percent based on total body weight of fish a repeat fry, took a day.The results showed that treatments were between body weight of fish are significant differences observed dust (P<0.05). The highest weight gain in six weeks feeding fry were completely GROWTH and increased starvation decreased.

Forty eight 8-month-old male goats were divided into three groups. In each group, eight goats were feed restricted for 45, 60 or 75 days, and eight goats served as the control. Restricted groups were fed with a maintenance ration, and the control goats were fed with a ration supporting 50 g of daily weight gain. At the end of restriction period, the restricted goats were offered the same ration as the control goats. When the average weight of the 75-day restricted goats approached that of the control, the goats were slaughtered. The carcass, several organs, carcass cuts and dissectible (trimmed) fat were weighed, and the chemical composition of the meat was determined. Feed restriction decreased the proportion in live weight of the dissectible fat, internal fat, liver and testis weight, meat dry matter and fat content, but the proportion of intestinal and splenic weights, and meat protein content were increased. Re-alimentation after 75 days of restriction was associated with a greater daily gain and less internal fat. Other measurements were not different from the control. Data showed that 8-month-old native kids are capable of considerable COMPENSATORY GROWTH after 75 days of feed restriction without any deleterious effect on carcass co mposition.

This study was carried with aim to investigate the restriction of feed, COMPENSATORY GROWTH and the effect of probiotic (Bacilact) on GROWTH performance, food productivity, survival and carcass composition of rainbow trout. Experiment was performed using a completely randomized design with three treatments consist of without hungry and basilicate treatment, feed restriction treatments with and without Bacilact during 2 weeks. The treatments were fed in re-feeding phase, to satiety for 4 weeks. The number150 of rainbow trout larva were fed with an average weight of 21. 20 ± 1. 31 g with the experimental treatments during 42 days breeding period. The results showed that the effect of treatments on weight and length GROWTH, feed conversion ratio, daily GROWTH ratio, specific GROWTH ratio, survival rate, condition factor and survival rate were significant (P<0. 05). Also, the effect of treatments on FER, PER, protein and fat percent carcass was significant (P<0. 05). The diet containing probiotic with Bacilact compared to without Bacilact group improved the survival rate of rainbow trout. Regarding the higher SGR, the results showed that COMPENSATORY GROWTH process in fish with 2 weeks of starvation and re-feeding with Bacilact is more than re-feeding without Bacilact. In conclusion, this study showed that probiotic (Bacilact) had a positive effect on GROWTH and nutritional factors as well carcass composition in comparison to re-feeding without Bacilact in rainbow trout.

One of the major problems in aquaculture is to achieve a balance between fish GROWTH rate and optimal use of fish food. Successful rearing of fishes depends on food availability for nutrition to guarantee the health and GROWTH of larval stages. A COMPENSATORY GROWTH is a phase of rapid GROWTH following feed restriction in such critical situations which it is observed in fishes.This experiment was conducted with common carp fingerlings (average weight of 0.668±0.074 g and 2.85±0.181 cm) for 6 weeks on 4 groups and 3 replications were as follows: Group 1: 6 weeks full feeding. Group 2: One week starvation+a week feeding with commercial food, Group 3: One week starvation+a week feeding with 103 colony forming units, Group 4: One week starvation+a week feeding with 106 colony forming units and Group 5: One week starvation+a week feeding with 109 colony forming units. Feeding rate of 10% based on the total weight of the fish was on. The results showed that there was a significant differences between groups in body weight and body length of carp fingerlings (P<0.05). The highest weight gain and length belonged to group 1 with six weeks full feeding. Results also showed that there is a significant differences in all of the groeth factors among groups (P<0.05). Results showed that starvation cause a decrease in GROWTH of carp fingerlings but in COMPENSATORY GROWTH use of the yeast Saccharomyces cervisiae made a better GROWTH after starvation period.

This experiment was carried out in order to investigate the effects of various levels and methods of feed restriction on COMPENSATORY GROWTH, performance and carcass characteristics of broilers. In a 3x3 factorial experiment, the effects of three methods of feed restriction: 1) Restriction by hull rice (20, 30, 40%), 2) Protein restriction (15, 25, 35% less than control), and 3) Physical restriction (10, 20, 30% less than control) in 4 replicates and 7 male birds (103-104g) in each replicate from 7th to 14th days of age on their subsequent performances were determined. After the termination of feed restriction period until slaughter time (49 days of age) all the treatments including control treatment were fed ad libitum. One bird from each replicate of experimental groups was slaughtered at the end of experiment. Restriction method did not have a significant effect on total feed intake (p>0.05) but levels' effect were significant (p<0.05). Neither methods nor levels had any significant effects on weight gain (p>0.05). Also, significant differences were not observed in methods and levels in comparison with control treatment at 7th weeks of age. Total feed conversion and relative GROWTH rate were affected by levels. (p<0.05). Methods and levels showed significant effect on carcass composition (Protein, fat and ash percent). Methods and levels did not significantly affected drumstick and breast percent, and the amount of abdominal fat (due to carcass weight).

Introduction & Objective: Usually the life duration of the fish species are faced with the problem of starvation naturally. Usually the case in winter, when during long migration to spawning and feeding on the living environment, decreased occur because of different reasons and cause severe loss of body energy reserves in fish.Material and Methods: Experiments were done in five groups and three replications: Control: 5 weeks full feeding Group 1: One week starvation + One week feeding, group 2: Two weeks starvation + One week feeding, group 3: Three weeks starvation + One week feeding, group 4: Four weeks starvation + One week feeding. The amount of dissolved oxygen was fixed on 5.5 - 6 ppm, the temperature 24-28oC and pH 7.5 to 8 were so controlled through the experiment. Carps fry were fed during the experimental period in control and COMPENSATORY GROWTH times with commercial food (containing: 8.7 % moisture, 11.2 % ash, 32 % protein and 10.5 % fat).Results: The results of carcass quality showed that there are significant difference at protein, fat, ash and fiber in different groups (P<0.05). The results showed that increase of starvation period causes a decrease at protein, fat, ash and fiber an increase ash carcass. Also, results showed that increase of starvation period causes a decrease carcass quality and survival in Cyprinus carpio fry.

To investigate the effect of wet diet in COMPENSATORY GROWTH period on live weight, feed convertion, feed intak and carcuss charactristics of broilers, a study was carried out in Ramin Agriculture Reaserch Station. In this study 240 chicks from Arian strain, randomly selected. Weight gain in 7Th week in 0, 10 and 20% of restrict, was 2031.13, 1905.13 and 1907 grams, respectively. The 0% restriction treatment ratio other treatments, was significantly (P<0.05). Ration form(dry and wet), had not effect on final live weight gain (P>o.o5). Feed consumption in 20% restrict treatment was less than other treatments, as such wet ratio consumption was less than dry ration (P<0.05). Food convertion ratio of 0% restrict treatment was less than 10 and %20 restrict (P<0.05). But food convertion ratio not significant between 10 and 20% restrict treatments (P>0.05). Food convertion cofficient of wet ration was less than dry ration (P<0.05). Concerning the carcass weight, braest weight, thight weight, intestine weight and abdominal fat weight, a significant difference between treatments was not found (P>0.05). Intesting weight in wet ration fed groups was (P<0.05).

This study was conducted to determine the effect of wet diets in COMPENSATORY GROWTH period on live weight, feed conversion ratio, feed intake and carcass characteristics of broiler chickens in Ramin Agriculture Research Station. 240 chicks from Arian strain, were randomly selected and divided into six experimental groups. Treatments were assigned in a Completely Random Design with Factoria l(3*2) arrangement, including 3 levels of restriction (0%, 10% & 20%), and 2 forms of ration (dry and wet), with 4 replicates, and 10 chicks per each replicate in treatment. Results showed that final live weight gain in 7Th week for 0%, 10% and 20% of restricted treatment, were 2031/13, 1905/13 and 1907 grams respectively. The aforementioned reducing levels decreased weight gain significantly (p<0.05), while change of ration from dry to wet, had no effects on final live weight gain (p<0.05). Feed intake of 20% restricted treatment was significantly (p<0.05) lower than other treatments, as well as the feed intake of wet ration that was less than dry ration. Feed conversion coefficient of 0% restricted treatment was less than 10% and 20% restricted treatments, but not significantly (p<0.05). Feed conversion coefficient of wet ration was less than that of dry ration (p<0.05). There was no significant difference between treatments (p<0.05) in terms of carcass weight, breast weight, thigh weight, intestine weight and abdominal fat weight, .Intestine weight was significantly different in wet ration with other treatments (p<0.05).
