“…The significant differences between the strains in feed efficiency and mortality rate are contrary to reports of insignificant differences by Dozier et al (2003) and Benyi et al (2009). The significant strain difference in abdominal fat in this study supports a similar observation by Santos et al (2005) and Benyi et al (2010). A positive genetic correlation ranging from 0.21 to 0.36 exists between live weight and abdominal fat percentage (Chambers 1990).…”

The effects of 6, 10 and 14 days of skip-a-day feed removal during the starter and grower periods on the growth performance of Ross 308 and Hubbard broiler chickens were studied in a 49-day production period. Ross 308 was superior to Hubbard in weight gain, market weight and feed utilization but consumed more feed, deposited more abdominal fat and had a higher mortality rate. Overall, feed removal improved feed efficiency, had insignificant effects on abdominal fatness and mortality rate and reduced feed intake, weight gain and market weight. On each restricted-feeding regime, the birds gained as much weight as their fully fed counterparts during the period of resumed full feeding but were unable to compensate fully for the weight loss and were lighter at the end of the trial. It is suggested that for profitable broiler production under tropical conditions, Ross 308 and skip-a-day feed removal for less than 6 days from 7 to 17 days of age be considered.

“…A number of variations of feed restriction including limiting the time of daily access to feed (Khetani et al, 2009;Onbasilar et al, 2009;Mohebodini et al, 2009), removal of feed for up to 8 h a d or skip-a-day feeding, allowing birds to feed only once/h and feeding once every other day (Demir et al, 2004;Khajali et al, 2007;El-Fiky et al, 2008;Benyi et al, 2009Benyi et al, , 2010Boostani et al, 2010;Saffar & Khajali, 2010), have been evaluated but results have been conflicting (Navidshad et al, 2006;Cornejo et al, 2007;Khetani et al, 2009;Ghazanfari et al, 2010). However, Mohebodini et al (2009) on the respective research indicated that although intermittent feeding through free access to feed during four periods of 2 h (06:00-08:00, 12:00-14:00, 18:00-20:00, and 24:00-02:00) from 7-21 d of age had lower on body weight gain than control (436.3 vs 495.3 g), but had no effect on weight gain during realimentation period from 22-42 d of age.…”

ABSTRAKPenelitian ini bertujuan untuk menguji pengaruh pembatasan waktu makan terhadap konsentrasi hormon tiroid dan metabolit darah ayam broiler selama periode pembatasan dan pemulihan. Sebanyak 400 ekor ayam broiler unsexed strain Lohmann umur 7 hari ditempatkan pada 5 perlakuan dengan menggunakan rancangan acak lengkap dan dianalisa menggunakan ANOVA. Perlakuan terdiri atas: ransum yang diberikan ad libitum (R-0); ransum yang disediakan 2 jam pada pagi hari dari pukul 08:00-10:00 dan 2 jam pada sore hari dari pukul 16:00-18:00 dari umur 7 hingga 14 hari (R-1) dan umur 7 hingga 21 hari (R-2); ransum disediakan 4 jam pada pagi hari dari pukul 08:00-12:00 dan 4 jam pada sore hari dari pukul 16:00-20:00 dari umur 7 hingga 14 hari (R-3) dan umur 7 hingga 21 hari (R-4). Setiap perlakuan memiliki ulangan sebanyak 4 dengan jumlah ayam sebanyak 20 ekor/unit. Konsentrasi hormon tiroid dan plasma albumin pada R-2 dan R-4 lebih rendah (P<0,05) daripada R-0 selama pembatasan waktu makan dari umur 7 hingga 21 hari. Konsentrasi hormon tiroid dan metabolit darah tidak berbeda nyata diantara semua perlakuan selama periode pemulihan dari umur 21 hingga 42 hari. Disimpulkan bahwa konsentrasi hormon tiroid triiodotironin dan tiroksin (T 3 dan T 4 ) dan plasma metabolit darah (albumin) menurun selama pengaturan waktu makan 4 dan 8 jam/hari dari umur 7 hingga 21 hari, akan tetapi, kondisi demikian kembali normal selama periode pemulihan. Kata kunci: broiler, hormon tiroid, metabolit darah, pengaturan waktu makan ABSTRACTThe present study was conducted to determine the effect of feeding time restriction on thyroid hormone and blood metabolites concentration of broiler chickens during feed restriction and realimentation period. Four hundred of 7 days-old unsexed broiler chicken of Lohmann commercial strain were arranged in a completely randomized design with 5 treatments and analyzed based on ANOVA. The treatments were: chicks fed ad libitum as a control treatment (R-0); chicks had free access to feed during two periods of 2 h (08:00-10:00 and 16:00-18:00) from 7-14 d of age (R-1) and 7-21 d of age (R-2); chicks had free access to feed during two periods of 4 h (08:00-12:00 and 16:00-20:00) from 7-14 d of age (R-3) and 7-21 d of age (R-4). The treatments consisted of 4 replicates with 20 chicks each. During feeding time restriction from 7 to 21 d of age, thyroid hormone and albumin plasma concentration of R-2 and R-4 were lower (P<0.05) than R-0. There were no statistical differences among the treatments on thyroid hormone and blood metabolites during realimentation period from 21 to 42 d of age. It is concluded that thyroid hormone triiodothrionine and thyroxine (T 3 and T 4 ) and blood metabolite (albumin) decreased during feeding time restriction for 4 and 8 h per d from 7 to 21 d of age and it returns to normal during realimentation period.

“…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).…”

“…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).…”

Temporary feed restriction partially protects broilers from 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.
