“…Therefore, it was supposedly that metabolic rate decreased during feed restriction causes hormonal activity associated with energy metabolism and growth declined. This result is in line with observation of Azis et al (2011) who found that growth performance of broilers decrease during feed restriction. This might be caused by the low basal metabolism and thus allows the organism to spare energy by decreasing basal metabolism (Hornick et al, 2000).…”

“…These findings indicate that T 4 and T 3 concentrations of the feed restricted broiler were normalized and remain as the value of ad libitum broilers during realimentation period. These results accordance with findings Azis et al (2011) that feed restricted broilers during starter period (7-21 d of age) had normal growth during realimentation period (21-42 d of age) so that compensatory growth and normal body weight could be achieved at 42 d of age.…”

“…These results indicate that the plasma total protein and globulin have not changed due to feed restriction. Although there were indications of intake protein decreased (12.77 vs 15.04 g/bird/d) during feed restriction from 7-21 d of age (Azis et al, 2011), however, it would not decrease protein reserves in the body. Plasma protein was an indication of protein reserve in the body that can reflect the ability of the chicken store "reserve" protein even after the animal has reached its maximum capacity for depositing tissue.…”

“…Therefore, restriction on feed availability through feeding time restriction may be a solution to these problems. Overwhelming evidence exists that feeding time restriction improves feed efficiency compared with ad libitum feeding (62% vs 58%), increased production index (329.04 vs 304.27), and decreased feed cost (6.42%) in production per kg body weight of broiler chickens (Svihus et al, 2010;Azis et al, 2011).…”

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.

“…Suci et al (2005) menyatakan bahwa pertumbuhan kerangka yang sempurna akan mempengaruhi pertumbuhan selanjutnya. Azis et al (2011) menyebutkan bahwa keberhasilan pertumbuhan kompensasi diperlihatkan dengan pencapaian berat badan normal pada periode pemulihan. Hal demikian terlihat dari berat badan akhir yang dicapai pada kelompok ayam yang mendapat pembatasan waktu makan tidak berbeda dengan kelompok ayam yang diberi pakan ad libitum pada umur 35 dan 42 hari pada broiler unsexed strain Lohmann.…”

INTISARIPenelitian ini bertujuan untuk mempelajari pengaruh level protein pakan yang berbeda selama periode starter (0-9 minggu) terhadap pertumbuhan kompensasi (9-12 minggu) pada ayam betina hasil persilangan ayam kampung jantan dan ayam ras petelur betina. Tiga puluh dua ekor ayam betina umur sehari dibagi secara acak menjadi 4 kelompok perlakuan yang berbeda. Selama 9 minggu pertama, setiap kelompok diberi pakan 4 perlakuan yang berbeda: P1 pakan berprotein 21,13%, P2 pakan berprotein 18,71%, P3 pakan berprotein 16,58%, P4 pakan berprotein 14,79%. Pada umur 9 minggu, delapan ayam betina dari setiap kelompok perlakuan dibagi menjadi 4 ulangan. Semua ayam diberi pakan P1 hingga akhir penelitian untuk mendapatkan pertumbuhan kompensasi. Variabel yang diamati adalah konsumsi (pakan, protein, energi), berat badan akhir, pertambahan berat badan, konversi pakan, rasio efisiensi protein, dan rasio efisiensi energi. Data yang diperoleh dianalisis dengan analisis variansi rancangan acak lengkap pola searah, dan perbedaan rerata perlakuan diuji dengan uji Duncan ' s Multiple Range Test. Hasil penelitian menunjukkan bahwa level protein pakan selama periode starter tidak berpengaruh nyata terhadap konsumsi pakan selama periode pertumbuhan kompensasi. Konsumsi pakan P3 dan P4 selama periode starter menghasilkan pertambahan berat badan dan konversi pakan lebih baik selama periode pertumbuhan kompensasi daripada ayam dengan pakan P1. Pertumbuhan kompensasi tertinggi dicapai pada ayam dengan pakan P3 dan penambahan level protein sampai 21,13% (P1) tidak berpengaruh terhadap berat badan akhirnya. Konsumsi protein dan energi berbeda tidak nyata di antara keempat perlakuan pakan, namun rasio efisiensi protein dan energi pada ayam umur 9-12 minggu dengan pakan P3 dan P4 lebih baik daripada ayam dengan pakan berprotein yang lebih tinggi. Kesimpulan penelitian ini penambahan level protein di atas 18,71% pada ayam betina hasil persilangan ayam kampung jantan dan ayam betina petelur tidak berpengaruh nyata dalam meningkatkan pertumbuhan berat badan dan bobot akhir.(Kata kunci: Persilangan ayam kampung, Pertumbuhan kompensasi, Protein pakan) ABSTRACTThe experiment was conducted to examine the effect of various dietary protein levels on compensatory growth period (9-12 weeks)

Feed restriction can be used in an attempt to save feed costs in the broiler business because it can encourage compensatory growth in broilers. This study was conducted to determine the effect of restricted feeding through the fasting method on growth performance, carcass traits, digestive organs, blood hematology, and intestinal histomorphology of broilers. A total of 240-day-old male New Lohmann broilers were randomly assigned to two treatments: ad libitum feeding (AF) and restriction feeding (RF). Restricted feeding is carried out by fasting method once a week after the brooding period at 10, 17, 24, and 31 d. Each treatment was replicated in 15 groups (each replicate consisted of 8 broilers). Data collected during the study were broiler growth performance, carcass traits, relative weight of digestive and immune organs, blood hematology, and intestinal histomorphology of broilers. The data obtained were statistically analyzed with an independent t-test analysis. The results showed RF decreased body weight gain at 21 d but was not different at 33 d than the AF group. The RF group had an increase in jejunum relative weight, jejunum villus width, and villus: Crypt ratio. In conclusion, feed restriction through the fasting method can be implemented without negative effects on final performance, carcass traits and immune system.
