“…Packed Cell Volume (PCV), Red Blood Cells (RBC) and White Blood Cells (WBC) counts showed significant (P < 0.05) decreasing treatment effects (Table 4) and were directly proportional to dietary crude protein levels. This finding is in agreement with the reports of Jean (1993) and Talebi et al (2005) that diet is one of the factors influencing RBC and WBC in the same individuals. However, haemoglobin, neutrophils and lymphocytes values did not differ (P > 0.05) across treatments.…”

This study assessed the effects of dietary crude protein on performance and nitrogen economy of broilers. Chicks were allotted to 22, 20, 18 and 16% crude protein corn-soy diets in a completely randomized design for forty-two days. Several essential amino acids were observed to be deficient compared to recommendations for broiler chicks as the dietary crude protein level reduced. Feed intake, weight gain, feed to gain ratio, faecal nitrogen, nitrogen retention, anthropogenic potential and dressing percentage were influenced (P < 0.05) by the dietary treatments. However, mortality was not significantly different (P > 0.05). Feed intake, weight gain, nitrogen intake and output were significantly (P < 0.05) depressed as the CP level reduced. However, the best (P < 0.05) nitrogen retention and percentage faecal nitrogen was recorded for broilers fed 20% crude protein diet. Serum total protein, albumin, uric acid, creatinine and glucose were affected (P < 0.05) across treatments. It was concluded that there is a limit to which dietary crude protein of broilers could be reduced without any detrimental effects on the performance and nitrogen economy of the birds, even when the requirements for methionine and lysine has been met, as several other amino acids could be limiting. Consequently, to achieve significant improvement in nitrogen economy and reduction in amount of faecal nitrogen, 20% crude protein diets could be fed to broilers. However, there may be need to further manipulate the amino acid profile of the diet so as to improve its performance to be at par with higher crude protein diets.

“…It has been noted that significant changes in the serum biochemical parameters can be related to the both pathological and nutritional status of individual animals (Aldu-hafeez et al 2009)The values of examined hematological parameters were according to the reported range of broilers (Talebi et al, 2005). The measured parameters of present experiment were age dependent which are disagrees with findings of Talebi et al (2005) in broiler chickens. The changes in Hb concentration, erythrocyte count, haematocrit level and differential leukocytes may indicate stress as reported by Hrabčáková et al (2014), while the changes in erythrocyte, Hb and pack cell volume may reflect an alteration of energy status in chickens as reported by Karamanlis et al (2008) and Alabi et al (2015).…”

The aim of the present study was to determine the effect of different bedding materials on the, hematological and serum biochemical parameters of the broiler chickens. A completely randomized design was employed for the research in which the treatment were five bedding materials (rice hulls, groundnut hulls, wood shaving, sharp sand and control). The treatments were replicated three times each with ten birds in each experimental unit. The birds were brooded for two weeks before the experiment begin. The blood samples were collected at day 56 of experiment for hematological and serum biochemical analysis. There was no significant difference in the glucose, serum total protein, globulin, calcium, sodium, total bilirubin, conjugated bilirubin, and serum alanine transferase, but there was a significant difference in serum cholesterol, albumin, bicarbonate and serum aspartate transferase within the groups. The findings also indicated in the hematological parameters that bedding materials caused significant difference in the hemoglobin content, white blood cell count and mean corpuscular hemoglobin, but no significant differences in the other parameters (Heterophils, monocytes, basophils, lymphocytes, mean cell volume and packed cell volume) were seen. The results suggested that rice, hulls, groundnut hulls and sharp sand can serve appropriately as bedding materials for broiler production, with compatible effects on serum biochemical and hematological parameters.

“…Significantly higher values of red blood cells, Hb and PCV were recorded in broilers fed high protein diets than those fed low protein (Mirtuka & Rawnsley, 1997). Talebi, Asri-Rezaei, Rozeh-Chai, and Sahraei (2005) have showed that the number erythrocytes of animals in good health vary with diets and clinical conditions of the animal.…”

In this experiment a total of 300 d-old broilers (Ross 308) were randomized across 20 floor pens and reared up to 42 d. Treatments includes: 1) A normal-protein diet (NPD) was formulated according to the Ross 308 recommendation (2014) by corn and soybean meal, 2) A reduced-protein diet (RPD) was prepared with dietary protein reduced by 12 g kg-1 (1.2%) relative to the NPD, 3) HMB+ RDP, 4) CLA+RDP and 5) CLA+ HMB+ RDP. The results showed that broilers fed HMB diet had higher Average Daily Gain (ADG) and Feed Conversion Rate (FCR) significantly improved by HMB during the grower or the whole period (p < 0.05). Titer of serum antibodies of Newcastle disease was maximum in treatment supplemented with CLA+HMB compared to the control (RPD) in day 42. In comparison with the control, feeding CLA increased Lymphocyte and decreased heterophil and H/ L ratio (p < 0.05). Insulin hormone secretion increased by dietary HMB (p < 0.05). Red Blood Cells (RBC) and Hemoglobin (Hb) was significantly increased by HMB supplemented diet (p < 0.05). It could be concluded that supplementations of HMB and CLA together in reduced-protein diet have positive effect on growth performance, immune system and hematological parameter.
