“…Summers et al (1990) investigated a 50 % feed restriction program in 5-11-day-old broilers and did not report significant differences in carcass weight, whereas in other feed restriction studies carcass weight was increased (Tumova et al, 2002). In the present study, there was a significant effect of feed restriction on eviscerated carcass weight.…”

“…It was observed that during the period of restricted feeding, as expected, the growth rate was less in the birds on a restricted diet than in those fed the full diet (data not shown), but the former did compensate for this when on full rations. It is generally accepted that after restriction, compensatory growth will be attained (Summers et al, 1990;Lee and Leeson, 2001). Feeding a high-energy and protein diet to previously restricted broilers results in better growth compared to birds fed in the standard way.…”

Abstract. The effects of the restriction of the advised daily feed intake (ADFI) during 1 or 2 weeks on broiler body weight (BW) and carcass composition were studied. A total of 150 1-day-old male broilers (Ross-308) were randomly allotted to a control and four experimental treatments with three replicates per treatment. Broilers were subjected to a feeding restriction equal to 75 and 50 % of ADFI, either for a 7-or a 14-day period, between the 7th and 14th and 7th and 21th day of age, respectively. The BW and carcass composition were determined on day 42. From the findings, neither of the two levels of restriction nor the two time intervals had significant effects (P > 0.05) on the BW or breast and leg weight and proportion, liver and most of the body components. However, the feeding treatments show a tendency (P = 0.078) to influence the BW, with birds fed 75 % of ADFI for 14 day being heavier than the control group. For eviscerated carcass weight, an effect (P = 0.002) was observed, with birds fed 75 % of ADFI for 14 day having heavier carcasses (P < 0.05) than those in control group. The abdominal fat, both with regard to weight and proportion, was slightly influenced by dietary treatments (P > 0.05). From our results, it can be concluded that the applied feeding restrictions have a neutral or slightly beneficial effect on broiler growth traits and carcass composition.

“…Os resultados do presente trabalho mostraram que a quantidade de gordura abdominal não sofreu nenhum efeito ou interação significativa (P>0,05) dos diferentes níveis de restrição utilizados, mas sim, da idade (P<0,01), na qual as aves mais velhas apresentaram maiores quantidades de gordura abdominal (Tabela 3). Summers et al (1990) e Yu et al (1990) também não observaram diferenças na quantidade de gordura abdominal aos 49 e 56 dias de idade, respectivamente, entre frangos alimentados ad libitum ou restritos precocemente. Entretanto, Baziz et al (1996) sugeriram que a determinação da gordura abdominal não deveria ser o critério mais importante para se medir a deposição de gordura nas aves, pelo fato dos mesmos apresentarem deposição subcutânea.…”

O objetivo deste trabalho foi avaliar a influência do nível de restrição alimentar sobre o ganho compensatório e composição da carcaça de frangos Ross. Foram utilizados frangos machos, submetidos a restrição alimentar quantitativa de 30% e 70% do consumo diário das aves alimentadas ad libitum, entre o 8º e o 14º dias de idade e realimentados ad libitum até 42 dias de idade, em um experimento inteiramente casualizado, segundo um esquema em parcelas subdivididas, tendo como parcelas o programa alimentar (ad libitum, restrição 30% e 70%) e subparcelas a idade das aves (dias). O ganho de peso, peso da carcaça, peso do intestino e quantidade total de gordura dos frangos restritos a 70% foram significativamente menores aos 42 dias de idade; no entanto, não foram verificadas diferenças significativas quanto a estes parâmetros entre frangos restritos em 30% e os alimentados ad libitum. A conversão alimentar, o comprimento do intestino e a gordura abdominal não foram afetados pelo programa alimentar. Os resultados obtidos nestes experimentos evidenciam que frangos de corte submetidos a restrição alimentar de 30% apresentaram ganho compensatório durante o período de realimentação; no entanto, a restrição de 70% é muito severa, afetando de forma negativa tanto o desempenho quanto a qualidade da carcaça dos frangos.

The effects of different combinations of nutritional background, feeding regimes and dietary compositions on growth responses of the Atlantic cod have been examined Alternating short periods (1-3 weeks) of food deprivation with unlimited prowslon of food depressed growth below that of controls, but cod that were fed on alternate weeks (1 1) were larger than those that were exposed to 2 or 3 week periods of deprlvahon and feeding (2 2 or 3 3) Thus, periods of food deprwatmn of short duration were insufficient to reduce any marked compensatory growth response When cod were deprived of food for longer periods a compensatory growth response was observed On receiving excess food supplies following 8 weeks of food deprivation the fish grew more rapidly than the controls and had completely recovered body weight within 12 weeks The greatest compensatory growth response was shown by cod in poor condition (lowest condition factor), because at the end of an 18 week growth trial there were no differences In body weight between fish irrespectwe of their initial condition Both sexes displayed a compensatory growth response
