Effect of Dietary Supplemental Ginger on Broiler Performance, Carcass Characteristics and Blood Profile

A study using one hundred unsexed day-old broiler chicks (Ross 308), 25 birds/treatment was conducted to evaluate the effect of ginger powder as natural feed additives on the growth performance, carcass traits and blood parameters of broiler chickens. Four dietary treatments were formulated to meet the nutrient requirements of broiler chicks containing ginger powder at levels 0%, 0.2%, 0.4% and 0.6%. The results showed that no significant differences were recorded in body weight and body weight gainbetween different experimental groups. Birds fed diets supplemented with ginger exhibited better feed conversion (P>0.05) and lower feed intake than control birds. The measurements of carcass traits, hematological values and serum biochemical parameters showed no marked variation between the treated groups. It could be concluded that ginger powder at the used levels in this experiment has not potential to be used as a growth promoter in broiler chicks.

Performance and physiological responses of broiler chickens to supplemental guanidinoacetic acid in arginine-deficient diets

ABSTRACT1. The present experiment was designed to examine arginine (Arg)-sparing effects of guanidinoacetic acid (GAA) on production performance, intestinal morphology and certain blood parameters in broiler chickens.2. A total of 300 male broiler chicks (Ross 308) were randomly allotted to 5 dietary treatments in a completely randomised design during 1–15 and 15–35 d rearing periods. Experimental treatments consisted of a basal diet with a reduction in Arg content (CON−; starter: 12.1 g/kg and grower: 11.3 g/kg Arg), a CON− diet supplemented with synthetic Arg equal to the required Arg level (CON+; starter: 13.80 g/kg; grower: 12.37 g/kg) and CON− diet supplemented with three levels of GAA (GAA0.6; GAA1.2; and GAA1.8; g/kg).3. Supplemental GAA at 0.6 and 1.2 g/kg reduced the adverse effects of the CON− diet on weight gain and feed conversion ratio in the starter period, equal to the effect of CON+ diet. During the entire rearing period, such an effect was only seen for broilers fed CON− diet supplemented with 1.2 and 1.8 g/kg GAA (P < 0.05). Proportional weights of liver and abdominal fat were decreased in birds fed diets containing supplemental Arg and 1.8 g/kg GAA compared to the CON− broilers (P < 0.05). Jejunal villus height and villus height to crypt depth ratio were increased in broilers receiving the CON− diet (P < 0.05). Serum concentration of nitric oxide increased when the CON− diet was supplemented with either Arg or 1.8 g/kg GAA (P < 0.05).4. Dietary inclusion of GAA had an Arg-sparing effect, whereby 1.2 and 1.8 g/kg of supplemental GAA resulted in greater growth performance during the starter and entire rearing periods, respectively. Supplementation with 1.8 g/kg GAA had significant effects on some carcass and physiological parameters.

Effects of protease supplementation of low protein and/or energy diets on growth performance and blood parameters in broiler chickens under heat stress condition

The effects of feeding low dietary crude protein (CP) and/or metabolisable energy (ME) with or without supplemental protease on growth performance, carcase characteristics and physiological responses in broiler chickens were investigated under cyclic heat stress condition. A total of 350 day-old male broiler chicks were fed with one of the following seven experimental diets: (1) recommended-CP and recommended-ME (RPE, served as control); (2) recommended-CP and low-ME (RPLE); (3) recommended-CP and low-ME with protease (RPLEP); (4) low-CP and recommended-ME (LPRE); (5) low-CP and recommended-ME with protease (LPREP); (6) low-CP and low-ME (LPE) and (7) low-CP and low-ME with protease (LPEP). From 22 to 42 d of age, half of the chickens from each dietary group were exposed to 34 ± 1 °C for 7 h daily (heat stress), whereas the other half were raised at constant 23 ± 2 °C (normal temperature). Supplementation of protease to RPLE, LPRE and LPE diets had no significant effects on feed intake (FI), weight gain (WG) or feed conversion ratio (FCR). Diet had no effect on serum glucose, total protein, certain acute phase proteins (APPs), corticosterone or breast yield. Regardless of protease supplementation, heat stressed birds had significantly lower FI, WG and breast yield, and higher FCR, APPs and corticosterone compared to birds raised in normal temperature. In conclusion, dietary supplementation of protease to low CP and/or ME diets showed negligible effects on growth performance, carcase characteristic and physiological responses in broiler chickens under heat stress condition. The inclusion of microbial protease in broiler diets could be considered by poultry industry as an effective nutritional tool for reducing ME or CP, in order to decrease abdominal fat deposition, improve feed efficiency and increase the profit margin.HighlightsProtease supplementation has no specific help for broilers under heat stress.Feeding low CP and/or ME diet is not stressful for broiler chickens.

Choosing sample sizes for various blood parameters of broiler chickens with normal and non-normal observations.

Experimental power is a measure of the ability of an experiment to detect differences between treatment means. Researchers design experiments and then calculate the probability that differences are simply due to chance, the null hypothesis. The objective of the analyses reported here was to determine the appropriate number of samples to demonstrate significant differences of various magnitudes from broiler chicken blood constituents. Over 800 samples were taken for a study of the effects of sample storage time, serum vs. plasma, light intensity, and fed vs. fasted birds on blood cholesterol, triglycerides, uric acid, glucose, total protein (TP), albumin, globulin, alanine aminotransferase (ALT), aspartate aminotransferase, gammaGT, creatinine, alkaline phosphatase, Ca and P. Various transformations increased the QQ plot R2 values from 0.000 to 0.149 or 0.00 to 17.62%. Most of the QQ plot R2 values were at or above 0.90. The 1/x2 transformation of blood P data showed the biggest increase in QQ plot R2 (0.846 to 0.995). The different standard deviations and coefficients of variation (CVs) found for each variable resulted in widely different numbers of replicates needed to detect differences in 2 treatment means. The extremes were glucose with a CV of 6.9% and ALT with a CV of 39.7%. For glucose, 15 replicates are needed to find a 10% difference in 97% of experiments; for ALT, 15 replicates would detect a 50% difference 91% of the time. The use of parameters such as cholesterol, glucose, TP, albumin, and globulin showed low CVs, indicating they may be considered as stable parameters. The lower CVs make it possible to find differences with a smaller number of replicates used in studies. As reported, the phosphorus values did not have a normal distribution of the data, so a transformation of these data could be an alternative to better discuss the results found.

Water supplementation of Moringa oleifera as a substitute for antibiotics on performance and blood parameters of broiler chickens

There is a serious public health concern of the use of antibiotics sub-therapeutically and/or as growth promoter in poultry feed and water. Therefore, there is an urgent need for alternatives. Moringa oleifera is a phytobiotic, which has been reported to possess antimicrobial and immuno-modulatory properties. This study aimed to investigate the effects of aqueous M. oleifera leaf extract (MOLE) supplementation on growth performance and hematological indices of broiler chickens. The 36 day-old broiler chicks (Cobb 500) were randomly divided into three dietary groups (group A, B and C) having 12 birds in each. The group A was considered as negative control which had received the basal diet and fresh drinking water. The group B was fed with basal diet and antibiotics (Ciprofloxacin) plus Vitamin B-complex mixed drinking water(Positive control). The group C was fed with basal diet and drinking water supplemented with 1% MOLE. Body weight, feed intake and feed conversion ratios of the birds were recorded on weekly basis. On day 35th of the feeding trail, blood samples from five birds per replicate were used for the study of hematological indices. Birds under Group C attained intermediate body weight (1892 g) and best FCR (1.48) those were comparable with that of Group B but better (p&lt;0.05) than those of Group A. There was a trend of decrease (p&gt;0.05) internal organs weight in Group C compared to other groups. However, zero mortality rate and similar hematological indices were observed in the birds across the treatments. Here, the results suggested that, the aqueous MOLE can be included in the drinking water of broiler chicken for reduced feed intake and improved feed conversion efficiency and it can be considered as an alternate to synthetic antibiotics as growth promoter to fight the emergence of antibiotic resistance phenomena in poultry industry.J.

The Effects of Propolis and Bee Pollen Supplementation on Biochemical Blood Parameters of Broilers

Abstract The aim of this study was to determine the effect of propolis and bee pollen on selected biochemical blood parameters in broiler chickens. This experimental study was conducted on 200 Ross 308 chickens of equally distributed sex, which were divided into five groups (a control group and four experimental groups). Throughout the whole study the control group of chickens was fed the control feed mixture while the feed mixture that was fed to the experimental groups of chickens contained additives (propolis and/or bee pollen, each supplemented separately or in combination in a certain proportion). The results obtained by this study are: significantly lower blood glucose, cholesterol and calcium levels (P &lt; 0.001), as well as significantly lower triglycerides levels (P = 0.002), but also significantly higher sodium and chloride (P &lt; 0.001), phosphorus (P = 0.004) and globulins levels (P = 0.027) in chickens of the experimental groups compared to the chickens of the control group on the 21st day of fattening. Furthermore, this study has found significantly lower blood glucose (P = 0.033) levels and significantly higher levels of total proteins and globulins (P = 0.003), as well as albumins (P = 0.040) in chickens of the experimental groups compared to the chickens of the control group on the 42nd day of fattening. It can be concluded that the application of propolis and bee pollen as additives in broiler feeds enables the production of more vital and healthier animals, which significantly improves the fattening of chickens.

Daily Rhythms of Blood Parameters in Broiler Chickens Reared under Tropical Climate Conditions.

Several studies carried out on humans and other mammals show that the temporal organisation of haematological parameters in the blood exhibit daily rhythms; however, such studies have been rare in poultry reared under a natural photoperiod. The present study investigated the occurrence of daily rhythms in blood parameters of broiler chickens kept under tropical climatic conditions. Ten 6–7-week-old broiler chickens served as subjects of the study. They were kept in standard individual cages under natural light-dark cycle and given access to feed and water ad libitum. Two milliliters of blood was collected from each bird via intravenous cannulae inserted into the wing vein. The blood samples were collected every 4 h over a 24-h period, starting from 09:00 h on the first day and completed at 09:00 h on the second day. The blood samples were analysed for erythrocyte, total and differential leucocyte counts. A trigonometric statistical model according to the single cosinor procedure was used to describe the periodic parameters and their acrophases, and ANOVA was used to determine significant differences. The results demonstrated the existence of daily rhythms in packed cell volume, haemoglobin, white blood cell, red blood cell, heterophil, lymphocyte, eosinophil and monocyte counts, while total protein displayed no rhythm. The characteristics of the haematological parameters showed that the acrophases were restricted to the light phase of the light/dark cycle, precisely at 09:00 h, except for eosinophil and heterophil counts, which had acrophases at 21:00 h. The amplitudes of the blood parameters varied, with packed cell volume having the greatest amplitude of 4.2 ± 0.5, closely followed by lymphocyte (3.4 ± 0.5) and heterophil (2.3 ± 0.2) counts. In conclusion, the results of the study demonstrated the existence of daily rhythms with diurnal acrophases in blood parameters of broiler chickens kept under natural photoperiods and tropical conditions.

Growth performance, digestibility, haematology, biochemistry, and some humoral immunity blood parameters of broiler chickens fed different levels of Boswellia serrata resin

The study determined the effect of three different levels of Boswellia serrata tree resin (BSR) supplementation in diets for broiler chickens on the growth performance, selected slaughter analysis, nutrient digestibility, as well as haematology, biochemical and some humoral immunity blood parameters. In total, 200 1-day-old broiler chickens were assigned randomly to four treatments. The broiler chickens were fed diets containing 0 (C), 1.5 (BSR1.5), 2 (BSR2), or 2.5% Boswellia serrata resin (BSR2.5). The BSR treatments improved (P &lt; 0.05) the feed intake and feed conversion ratio at breeding Days 22–35, but did not differentiate the nutrient digestibility in the diets. The best-quality carcass with a high proportion of muscles and low fat content (Control versus BSR diets, linear, P &lt; 0.05) was obtained in broiler chickens fed diets supplemented with 2% and 2.5% BSR. The blood profile was affected by the BSR treatments. The lymphocyte count increased linearly in blood (P &lt; 0.05) along the increasing amounts of BSR. The content of uric acid and aspartate aminotransferase activity in blood plasma decreased upon the BSR supplementation (Control vs BSR diets, linear, P &lt; 0.05; and Control vs BSR diets, linear, P &lt; 0.01, respectively). The resin of Boswellia serrata can be considered as a good botanical feed additive, which can have positive effects on the performance and health of broiler chickens.
