“…The present study agreed with the observation of Ballay et al (1992) who found that the age when the restriction was started (1, 7 or 13 days of age) had no effect on abdominal fat of sexed broilers. Our results (Experiment 1) also agreed with the observation of Santoso et al (1995b) who found that duration of restriction did not affect abdominal fat in sexed broilers.…”

“…They postulated that since lipogenesis in poultry occurs primarily in the liver, with unused fatty acids stored as trilgyceride in adipose tissue, lipid content in the liver would not be expected to be different in broilers exposed to different feeding treatments. However, this postulation was not wholly true, since Santoso et al (1993aSantoso et al ( , 1995b found that early feed restriction changed hepatic triglyceride content.…”

The study was conducted to evaluate the effect of early feed restriction on growth, fat accumulation and meat composition in unsexed broiler chickens. In experiment 1, three hundred and fifty one-day-old broiler chicks were divided into 7 groups. Each treatment group was represented by five replicates of ten broilers each. One group was fed ad libitum as the control group and the other six groups were fed 25% ad libitum (25% multiplied by amount of feed intake of ad libitum chicks at the previous day) for 4 or 6 days, 50% ad libitum for 4 or 6 days, and 75% ad libitum for 4 or 6 days. In experiment 2, five hundred broiler chicks were divided into 10 groups. Each treatment group was represented by five replicates of ten broilers each. One group was fed ad libitum as the control group. Three initial age at which broilers were restricted (2, 4 or 6 days of age) and three type of feed restriction (physical restriction, meal feeding and diet dilution) (3×3) were examined. They were restricted feeding for 6 days. Experimental results showed that broilers fed 25% ad libitum for 4-6 days tended to reduce leg meat fat with lower abdominal fat (p<0.05) (experiment 1). Breast meat fat was significantly higher in restricted broilers (p<0.01). Plasma triglyceride was higher in broilers fed 75% ad libitum for 4-6 days. In experiment 2, abdominal fat was lower in restricted broilers (p<0.05). Breast meat fat was significantly higher (p<0.01), whereas leg meat fat was significantly lower (p<0.05) in restricted broilers. Plasma triglyceride was significantly higher in physical feed restriction for 4 days, meal feeding for 4 days and diet dilution for 6 days (p<0.05). In conclusion, to reduce fat accumulation in abdomen and leg meat, broilers should be fed 25% ad libitum for 6 days started at 4 days, or subjected to meal feeding (6 hours per day for 6 days) started at 6 days.

“…In the rehabilitation period, chicks grow more rapidly to compensate for lost growth due to dietary restrictions (Summers et al, 1990;Bowes and Julian, 1998). Following the restricted feed program, the birds are fed a diet of high quality resulting in faster growth compared to the natural growth of the animal's age which is probably due to increased nutrient utilization; this phenomenon is called 'compensatory growth' (Pinchasov et al, 1993;Zubair and Leeson, 1994;Acar et al, 1995;Santoso et al, 1995;De Silva and Kalubowila, 2012;Butzen et al, 2013). Some researchers consider use of restricted feed programs and lighting programs as the key to reduce maintenance costs and to prevent metabolic abnormalities in modern strains (Jahanian et al, 1990;Fontana et al, 1992;Donald et al, 2000).…”

ABSTRACT. This study was carried out to evaluate the effects of physical feed restriction method with different intensity and duration on broiler performance. One hundred and fifty Ross-breed 308 male broiler chicks in a completely randomized design were divided into five experimental treatments. The treatments included physical limitations by 25% or 50% of recommended amount on feed of broilers in two periods of 7 or 14 days. One control group was used fed ad libitum. Each limitation's severity level was applied in τηρεε replications of 10 birds. All experimental treatments before and after the limitation period until slaughter (day 42) were fed ad libitum. The results showed that in total period broilers under the physical limitation of feed had significantly lower feed intake than controls (P < 0.05). In this research, methods and levels of physical restriction intensity and duration of feed had no significant effect on body weight for the whole experimental period. Methods and levels of food restriction severity and duration had significant effect on feed efficiency (P < 0.05).

“…Effect of restricted feeding on the deposition of fat in broiler chickens has so far been investigated extensively to reduce abdominal fat and body fat without loss of growth performance of broiler, summarized as a review by LEENSTRA (1986). There are a number of studies concerned with the fat deposition under the ad libitum feeding in broiler chickens which had been restricted the food intake for short period during the earlier stage of growth (PLAVNIK and HURWITZ, 1988, 1990, 1991YU et al, 1990;CABEL and WALDROUP,1990;BALLAY,1992;SANTOSO et al, 1993SANTOSO et al, , 1995. However, few investigations have been carried out to determine the relationship between the growth of muscle and fat deposition in broiler chickens which have been restricted the feed intake for considerably long time.…”
