This experiment was conducted to study the association of Ghrelin gene polymorphisms and expression levels with some productive and carcass traits of broiler chickens. Two hundred broiler chicks, one day old Ross308, were wing-tagged and reared under conventional conditions. Blood samples were collected individually of all birds to study of ghrelin gene polymorphisms by PCR-RFLP technique. Proventriculus was collected at 35 days of age from thirty birds of each groups sorted according to high, moderate and low growth rate to measure ghrelin gene expression by real-time RT-PCR. Result revealed that final body weight and weight gain were not significantly influenced by ghrelin gene , whereas body weight and weight gain of males and females with high ghrelin gene expression were significantly (p<0.01) higher than those of moderate and low ghrelin gene expression at  21 and 35 days of age. Ghrelin gene polymorphisms had no    significant (p>0.05) influence on carcass traits and edible organ weights, while significant (P < 0.01) differences were existed among high, moderate and low ghrelin gene expression groups  in carcass weight, breast, wing, neck and back relative weights. It is concluded that PCR- RFLP technique revealed no  significant effect for ghrelin gene polymorphisms on productive and carcass traits, whereas ghrelin gene expression had significant effect on productive traits.

Two hundred and forty Arbor Acre strain day old chicks were used to determine the effect of Maxigrain® enzyme fortification of dietary brewers dried grains (BDG). Eight groups of 30 birds each were fed four diets that contain 0, 5, 10 and 15 % BDG with or without Maxigrain in a 2x4 factorial arrangement. The research lasted for 28 days during which data were collected on performance, nutrient utilization and production cost. Significant (P<0.05) increased was observed in average final body weight, body weight gain and feed intake as dietary BDG increased. However, this effect was higher when enzyme was added to BDG respectively. Increasing the BDG from 0 – 15 % significantly (P<0.05) reduced cost of feed consumed and increased feed cost with enzyme addition. The reversed trend was observed with cost per kg gain of broiler chicks fed BDG with enzyme supplementation. Birds fed BDG with enzyme had significantly (P<0.05) better nutrient utilization than their counterpart group. It can be concluded that the incorporation of up to 15 % BDG with 100 mg/kg Maxigrain® supplementation enhanced performance and economics of production

This study was conducted to evaluate the growth performance and haematological profiles of broiler chickens served dietary inclusion of probiotics (Saccharomyces cereviasae) and enzyme (Bio-enzyme). One hundred and twenty, one day-old broiler chicks of Agrited strain were used for the study. The birds were randomly allotted to four dietary treatments. Each treatment contained 30 birds replicated three times to contain 10 birds per replicate in a completely randomized design experiment. The four dietary treatments were T1 Control (no probiotics and enzyme), T2 (had both probiotics and enzyme), T3 (probiotics only) and T4 (Enzyme only). The birds were given feed and water ad-libitum and the quantity of feed consumed each day was determined through weigh back techniques while the birds were weighed weekly throughout the experimental period. The experiment lasted eight weeks. The results showed significant (p<0.05) differences in the final body weight, total weight gain, average daily weight gain, total feed intake, average daily feed intake and feed conversion ratio. Chickens on treatment 2 had the highest final body weight of 3011.57g and performed better than chickens in other dietary treatments. Similar trend was observed in the haematological profile as treatment two were highest in value across the treatments and parameters measured except in packed cell volume where the highest value (36.33 %) was recorded in treatment 4. It was concluded from the study that treatment two which contained both probiotics and enzyme performed better and thus, recommended to farmers for broiler production.

The efficacy of tulsi (Ocimum sactum) and neem (Azadirachta indica) leaves extract as a growth promoter were studied in broiler. A total of 40 day-old broiler chicks were purchased from Kazi hatchery and after three days of acclimatization the chicks were randomly divided into four groups (n=10). No vaccination schedule was practiced and no antibiotic was added in ration of group A, B, C, and D respectively. Group A served control without any supplements while group B, C and D were supplemented with combination of tulsi and neem extract @ 1 ml, 2ml and 3 ml/liter of drinking water. Live body weight gain was recorded weekly up to 6th weeks and hematological studies were performed at 21st and 42nd day of experiments. At the end of 42nd day of experiment final body weight of group A, B, C and D were 1561± 12.10 g, 1698± 12.87 g, 1608± 12.04 g and 1763± 13.28 g, respectively. The birds of group D utilized their feed more efficiently among the treatment groups (p<0.05). The net body weight gain were, 1533± 11.98 g, 1443± 11.32 g and 1588± 12.10 g in treated groups compared to control group (1393± 11.07 g ) and total net profit per broiler was 19.08, 40.10, 20.68 and 45.07 Taka , respectively. Hematological parameterss (TEC, PCV, Hb and ESR) were not significantly changed among the treated and control group suggesting no side effects of herbal extracts in broiler. It can be concluded that tulsi and neem extract is economic and safe in broiler production.DOI: http://dx.doi.org/10.3329/bjvm.v11i1.17728 Bangl. J. Vet. Med. (2013). 11 (1): 1- 5

The aim of this study was to evaluate the effect of monochromatic light on broiler performance, fear and stress response during pre-slaughter handling and transportation. Two thousand unsexed one-day old Cobb broiler chicks were used. At day 34, two hundreds broilers of similar live body weight were selected and divided into two equal groups (2 group x 5 replicates). Broilers were reared under white light (WL) from 0-34 day. From 35 to 49 day, the first group was reared under WL and the second group under blue light (BL). Final body weight (FBW), tonic immobility reactions (TI), respiratory rate (RR), heterophils to lymphocytes (H/L) ratio and interlukien-1? (IL-1?) were estimated at day 49 before and after transportation. After transportation, weight of internal organs (liver, spleen, heart and bursa of fabricius) as a percentage of FBW was calculated. Results showed that there was a significant (P<0.05) increase in FBW and reduced weight loss due to transportation in broilers reared under BL. In broilers reared under BL: TI duration, RR, H/L ratio, IL-1? and weight of internal organs (except the heart) were significantly (P < 0.05) lower. The interaction effect of light and transportation on TI duration, RR, lymphocytes, H/L ratio and IL-1? were significant (P < 0.05). Therefore, it is suggested that BL may be a good tool for improving welfare and mitigating stress not only in pre-slaughter handling but also during transportation of broilers.

Abstract The effect of graded levels of grains of selim on the performance, gut microbial population and carcass characteristics of finisher broilers was investigated. Two hundred and four (204) 28 days old broiler chicks (Marshal breed) were randomly allotted to four treatments with each treatment having three replicates of 17 chicks each in a completely randomized design. Finely blended grains of selim was administered through drinking water on treatments 2, 3 and 4 at concentrations of 0.5, 0.7 and 0.9 g per litre while chicks on treatment 1 (control) received 1.0 g per 1.5 litre of antibiotics (Gendox). Chicks were fed ad libitum with isonitrogenous and isocaloric diets containing 20% crude protein and 3000 Kcal/kg metabolisable energy for four weeks. Results showed no significant (P > 0.05) differences among treatments in the final body weight, total weight gain, daily weight gain, total feed intake, daily feed intake and feed:gain ratio. There were differences in the microbial population of the gastro-intestinal tract with colony count decreasing as the concentration of grains of selim increases. Carcass characteristics and organ weights were similar (P > 0.05) except for thigh and spleen weights, and large intestine lengths where differences (P < 0.05) exist. Mortality ranged from 8.47% - 13.47% across treatments. The results indicated that grains of selim have antimicrobial and anthelminthic properties, and promote growth in broiler chickens

Abstract Background Heat stress is a significant problem in the poultry industry, causing a severe economic loss due to its detrimental effects on chickens’ health and performance. Dried plum (DP) is a good source of minerals, vitamins, antioxidants, and phenolic compounds. Studies have suggested that DP has several health benefits, such as maintaining the body’s redox system, immune status, and calcium hemostasis. Based on the health benefits of DP, we hypothesized that the dietary supplementation of DP would alleviate the detrimental effects of heat stress on broiler chickens. Results To test the hypothesis, day-old broiler chicks (n = 72) were randomly allocated to three treatment groups (n = 24/group): no heat stress (NHS), heat stress (HS), and heat stress with dried plum (HS + DP), and reared under standard conditions. The inclusion of 2.5% DP in the feed of the HS + DP group was made during the treatment period, while birds in other groups were provided with a standard finisher diet. After 21 days, birds in the HS and HS + DP groups were exposed to cyclic heat stress conditions (33 °C for 8 h during daytime) for 3 weeks, while those in the NHS group were reared under normal conditions (22–24 °C). Weekly body weight and feed intake were recorded to calculate the average daily gain (ADG), average daily feed intake (ADFI), and feed conversion ratio (FCR). Heat stress significantly decreased the final body weight, ADG, ADFI, and increased FCR compared to the NHS group, whereas dietary supplementation of DP significantly improved these growth performance parameters compared to the HS group. Furthermore, supplementation of DP significantly increased the expression of heat shock protein-related genes (HSF1, HSF3, HSP70, and HSP90), antioxidant-related genes (SOD1, SOD2, GPX1, GPX3, PRDX1, and TXN), tight junction-related genes (CLDN1, and OCLN), and immune-related genes (IL4, MUC2) in the ileum as compared to the HS group. The microbiota analysis showed significant enrichment of Bacillales, Christensenellaceae, Bacillaceae, Peptostreptococcaceae, and Anaerotruncus in heat-stressed birds supplemented with DP as compared to the HS group. Further, DP supplementation also significantly increased the concentration of acetate, propionate, and total VFA in the cecal digesta of the HS + DP group as compared to the HS group. Conclusion These findings suggest that DP supplementation effectively improved the growth performances and gut health parameters in the heat-stressed birds. Thus, dried plum can be a potential feed supplement to mitigate heat stress in broiler chickens.

Regulation Of Growth

An experiment was undertaken to investigate physiology of growth on broiler chickens under two differences of  temperature (18C and 32C) on final body weight gain, plasma concentration of T3 (triiodothyronine), plasma concentration of T4 (thyoxine) and plasma concentration of corticosterone (CTC). Body weight gain was highest significantly at forced-fed (at 18C=361.86 g/chicken/12 d; at 32C=345.02 g/chicken/12 d)  and it was lowest adlibitum-fed (at 18C=354.91 g/chicken/12d; at 32C=343.39 g/chicken/12 d).  Thus, rate of muscle protein syntesis (%/day) was lowest when the chickens were exposed adlibitum-fed (at 18C =7.40 %/day; at 32C =3.94%/day). Plasma concentration of T3 (triiodothyronine) was significantly decreased to exposed by adlibitum-fed (at 18C =1.45 ng/ml; at 32C=0.58 ng/ml); plasma concentration of T4 (thyoxine) was significantly decreased to exposed by adlibitum-fed (at 18C=5.95 g/dl; at 32C= 0.58 g/dl). However, plasma concentration of corticosteron (CTC) was significantly increased when the chickens were exposed by forced-fed (at 18C=9.49 ng/ml; at 32C=25.89 ng/ml). These results clearly show that plasma concentration hormones of thyroid and corticosteron (CTC) status are affected by temperature, forced-fed and adlibitum-fed, and may play an important role in the regulation of growth in broiler chickens.

Abstract The present study was carried out to compare the growth performance and carcass yield of broiler chickens reared in semi-intensive and conventional systems (Ross 308, n=120). Chickens were raised in a pen on wooden shavings for 21 days. On day 21 of age, chicks were assigned to 2 treatments (indoor treatment and semi-intensive treatment). The experiment was conducted at until 6 weeks of age. Production system has a significant effect on wing (P less than 0.05) and heart weight (P less than 0.01), but has no any effect on final body weight, hot or cold carcass weight, thigh, breast, back and neck, gizzard, liver and abdominal fat weights (P>0.05).  The final body weight, hot and cold carcass weight, thigh, wings and heart weights were affected by sex of birds (p less than 0.05) while breast, back, liver, gizzard and abdominal fat were not affected by sex (P>0.05). The nutrient level of carcass parts was not influenced by production system or sex (P>0.05). In our study, breast of birds reared under semi-intensive system had significantly lower ‘L’ (P less than 0.05), higher ‘a’ statistically different (P less than 0.01); while ‘b’ value was significantly (P less than 0.01) higher in skin of semi-intensive reared birds

A 49 day feeding trial was conducted to determine the effect of biologically upgraded cocoa pod husk meal (BCPHM) on the growth performance, haemato-biochemical indices and antioxidant status of broiler chickens. Three experimental diets were formulated at both starter and finisher phases in which BCPHM was added as an active feed ingredient at 0, 10, 20% and designated as diets 1, 2 and 3 respectively. One hundred and fifty day old Marshal broiler chicks weighing 39±2.5g/bird were allotted to 3 dietary treatments (10birds/replicate, 50birds/treatment) in a completely randomized design. The Average daily weight gain (ADWG), total weight gain (TWG) and final body weight (FBW) of broiler chicks fed diets containing 10% BCPHM was significantly (p˂0.05) higher than that of control and diet containing 20% BCPHM at starter phase. At finisher phase, the values of ADWG, TWG  and FBW were at par with that of control. Feed Intake was seen to increase as BCPHM increased in the diet at finisher phase. Carcass traits, relative internal organ weight, haemato-biochemcal indices of broiler chickens were similar across dietary treatment. Superoxide dimutase (SOD) and Catalase (CAT) of birds fed control diet were significantly (p˂0.05) higher than those of birds fed BCPHM based diets. Ten percent dietary inclusion of BCPHM appears optimal in broiler diet since beyond this level growth performance declined.
