“…This fact is in agreement with the findings of Zhan et al (2007) that the concentration of hormones T 3 (1.7 vs 2.1 ng/ml) and T 4 (55.3 vs 60.5 ng/ml) in feed withdrawal for 4 h/d (14:00 to 18:00) from 1-21 d of age were lower than the control. Evaluation of plasma biochemistry in bird allows the identification of metabolic alterations due to a realm of factors, including genetic type, husbandry conditions, age, physiological state and pathological (Harr, 2002;Gayathri et al, 2004;Jurani et al, 2004;Alonso-Alvarez, 2005). Changes of blood thyroid hormone concentrations are an indirect measure of the changes in thyroid gland activity and circulating thyroid hormones can be considered as indicators of the metabolic and nutritional status of the animals (Todini, 2007;Todini et al, 2007).…”

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.

“…However, considerable within-population variation may exist in haematological traits and may need to be incorporated to provide useful reference values. Age has been identified as a major factor that can influence blood parameters, and others, such as sex or stage of the breeding cycle, may also be important (Kostelecka-Myrcha 1985;Pastor et al 2001a, b;Campo and Davila 2002;Gayathri et al 2004;Villegas et al 2004;Baos et al 2006b;Kasprzak et al 2006;Jakubas et al 2008). However, our knowledge of the influence of sex and other factors on haematological parameters, especially in chicks, is limited.…”

Biochemical and blood cell parameters have commonly been employed as useful minimally invasive indicators of the health or nutritional status of many species. Here, we present data on a suite of commonly measured blood parameters from 342 White Stork Ciconia ciconia chicks of molecularly known sex. Samples were collected in western Poland during four breeding seasons (2005)(2006)(2007)(2008). We examine whether sex, and also season (year), nesting locality, hatch date and brood size, contributed to variation in these blood parameters. There were significant seasonal differences in levels of the heterophil/ lymphocyte ratio, red blood cell count, haematocrit, haemoglobin, mean corpuscular volume, mean corpuscular haemoglobin concentration, and particularly in white blood cell count. Significant nesting locality effects were detected in haemoglobin, mean corpuscular volume, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration. Hatch date, virtually synonymous with chick age, significantly negatively influenced (i.e. later hatch dates (younger chicks when sampled) had lower values of red blood cell count, haematocrit, haemoglobin and mean corpuscular haemoglobin concentration. Male chicks had significantly lower levels of red blood cell count, haematocrit, haemoglobin and mean corpuscular haemoglobin concentration. There was a significant sex/ hatch date interaction for red blood cell count, haematocrit and haemoglobin. Brood size did not significantly affect any of the analysed parameters. Our work shows that blood parameters are influenced by many factors, including sex and age of individuals, and such factors may need to be taken into consideration when using blood parameters as indicators of health. Such considerations are especially critical in the establishment of reference ranges of blood parameters which may be of use in captive rearing of this endangered species.

“…This showed that higher glucose concentrations result in better body conditions. Similar studies showed an increase in body mass and glucose concentrations during this period (mOe et al 2002, Gayathri et al 2004. During incubation, passerines usually gain mass -probably due to fat deposition and accumulation of fluids for brood patch formation (SiCk 1997).…”

“…Others tend to increase their foraging activity and are fed by their partners (LiFJeLd & SLaGSvOLd 1986, niLSSOn & Smith 1988, kern et al 2005. Thus, since their nutritional status is related to their body condition, we can identify information about the breeding strategies of birds by measuring their metabolites (hOLLmen et al 2001, vLeCk & vLeCk 2002, Gayathri et al 2004.…”
