“…However, in this study the feed conversion of batch showed significant difference (p > 0.05) among treatments evaluated 28 to 49 days. Zhan, Wang, Ren, Zhao, Li & Tan, (2007), also showed no difference in relation to the feed conversion, analyzing the effect of early food restriction in metabolic programming and compensatory growth in broiler.…”

This research was conducted to assess the compensatory gain in birds that have suffered severe food restriction and a reduced growth in its initial phase. A total of 144 birds were used in the Label Rouge lineage with average initial weight 239.90 ± 76.80 g, from 28 to 49 days. The experimental design used was a completely randomized design, where the birds were distributed in 18 boxes, containing 3 treatments and 6 replicates of 8 birds per cage. The treatments were as follows: birds with body weight of 150.73 ± 12.62 g, between weighing from 239.79 ± 13.14 g and heavy weight of 329.17 ± 24.89 g in different periods, from 28 to 35, 35 to 42 and 42 to 49 days of age, respectively. In relation to weight gain, the heavy birds, obtained better results when compared to the other. The feed consumption has changed in the three periods and, in the period of 42 to 49 days, the treatments did not differ among themselves. Feed conversion rates (p = 0.127) and feasibility (p = 0.6163) of birds do not differ in different periods.Keywords: Consumption, feed efficiency, poultry, severe restriction. ResumenEsta investigación se realizó para evaluar la ganancia compensatoria en aves que han sufrido graves restricciones alimenticias y un crecimiento reducido en su fase inicial. Se utilizó un total de 144 aves en el linaje Label Rouge con un peso inicial promedio de 239.90 ± 76.80 g, de 28 a 49 días. El diseño experimental utilizado fue el diseño completamente al azar, en el que las aves se distribuyeron en 18 cajas, con 3 tratamientos y 6 repeticiones de 8 aves por jaula. Los tratamientos fueron los siguientes: aves con peso corporal de 150.73 ± 12.62 g, entre el peso de 239.79 ± 13.14 g y peso de 329.17 ± 24.89 g en diferentes períodos, de 28 a 35, 35 a 42 y 42 a 49 días de edad, respectivamente. En relación al aumento de peso, las aves pesadas, obtuvieron mejores resultados en comparación con el otro. El consumo de alimento ha cambiado en los tres períodos y, en el período de 42 a 49 días, los tratamientos no difirieron entre sí. Los porcentajes de conversión alimenticia (p = 0.127) y de viabilidad (p = 0.6163) de las aves no difieren en diferentes períodos.Palabras clave: Consumo, eficiencia alimentaria, aves de corral, restricción severa.

“…Feed restriction is a management strategy, which is applied in the poultry industry in order to reduce the feed intake, to limit the early growth, to decrease the incidence of infectious, metabolic and skeletal disorders and to improve the nutrient utilization via compensatory growth (Zulkifli et al, 1993;Zhan et al, 2007;Thompson et al, 2008;Benyi et al, 2010). In the present study, the reduction in body weight as well as the change of feed conversion ratio in experimental groups where feed restriction was applied, is in agreement with the results of the study of Lee & Leeson (2001).…”

“…Feed restriction is applied in broiler chicks in order to take advantage of the growth compensation of birds and to reduce the feed conversion ratio. The growth compensation of birds defines the increased growth rate, when growth has been retarded by nutritional restriction and followed by ad libitum feeding (Shariatmadari & Torshizi, 2004;Zhan et al, 2007). In the beginning, feed restriction reduces the body weight, as a result of reduced feed consumption.…”

“…Several qualitative and quantitative feed restriction programmes have been tried in attempts to reduce the feed intake, limit the early growth and decrease the incidence of infectious, metabolic and skeletal disorders (Zulkifli et al, 1993;Zhan et al, 2007;Thompson et al, 2008;Benyi et al, 2010). The main target of feed restriction is to reduce the nutrients in the gastrointestinal tract, so that they can be utilized by neither birds nor intestinal microbiota (Tsiouris, 2010).…”

“…The effect of feed restriction on the growth rate, body weight and feed conversion ratio has been well documented (Zhan et al, 2007;Baghbanzadeh & Decuypere, 2008;Benyi et al, 2010). However, to the best of our knowledge, the feed restriction has not been evaluated as a specific control measure for necrotic enteritis.…”

The objective of this study was to investigate the effect of feed restriction on the intestinal ecosystem and on the pathogenesis of experimental necrotic enteritis in broiler chicks. To induce subclinical necrotic enteritis, an experimental challenge model using a specific diet formulation, Gumboro vaccination, oral inoculation of broilers with a 10-fold dose of attenuated anticoccidial vaccine and multiple oral inoculations with a specific strain of Clostridium perfringens was adopted. Two hundred and forty 1-day-old Cobb 500 broilers were randomly allocated to four groups: feed restricted, challenged, both feed restricted and challenged, and negative control. At 21, 22, 23 and 24 days of age, the intestines, gizzard and liver were collected from 15 birds in each group and scored for gross lesions. The intestinal digesta was collected for pH and viscosity determination. One caecum from each bird was taken for microbiological analysis. The application of feed restriction in birds challenged with C. perfringens reduced the necrotic enteritis lesion score significantly (P ≤ 0.05) and feed restriction significantly reduced (P ≤ 0.05) pH in the small intestine, the viscosity of the jejunum digesta as well as the C. perfringens counts in the caeca compared with the controls. In conclusion, feed restriction of broilers has a positive effect on the intestinal ecosystem and a significant protective effect against necrotic enteritis in the subclinical experimental model.

Nutritional limitation is a common phenomenon in nature that leads to trade‐offs among processes competing for limited resources. These trade‐offs are mediated by changes in physiological traits such as growth factors and circulating lipids. However, studies addressing the sex‐specific effect of nutritional deficiency on these physiological variables are limited in birds. We used dietary restriction to mimic the depletion of resources to various degrees and investigated sex‐specific effects on circulating levels of insulin‐like growth factor 1 (IGF‐1) and triglycerides in Japanese quails (Coturnix japonica) subjected to ad libitum, 20%, 30% or 40% restriction of their daily requirement, for 2 weeks. We also explored the association of both physiological variables with body mass and egg production. While dietary restriction showed no effects on circulating IGF‐1, this hormone exhibited a marked sexual difference, with females having 64.7% higher IGF‐1 levels than males. Dietary restriction significantly reduced plasma triglyceride levels in both sexes. Females showed more than six‐fold higher triglyceride levels than males. Triglyceride levels were positively associated with body mass in females while showed not association in males. Overall, our findings revealed sex‐specific expression of physiological variables under dietary restriction conditions, which coincide with body size.
