The study was conducted to investigate the phenotypic features, morphometry and production potentialities of indigenous dwarf chicken (IDC) of Bangladesh under intensive management condition. A total of 48 females and 12 males were collected from different districts and the experiment was performed at BAU Poultry farm for a period of 75 weeks. The predominant plumage and skin color were black and white, respectively. The average shank length, shank circumference and live weight (28 weeks) in adult males and females were 7.5 and 4.69 cm, 6.28 and 3.69 cm, and 1.77±0.38 and 1.10±0.077 kg, respectively. The reduction of live weight for dwarf male and female chickens relative to their normal shanked counterparts (NSC) at same age was 12.91 and 16.91%, respectively. Hen day egg production, average egg weight, average feed intake and FCR (feed conversion ratio) of IDC were recorded 37.43%, 38.25 g, 69.57g and 4.58, respectively. The average age and weight at sexual maturity were recorded as 166.53 days and 1093 g, respectively. IDC consumed 11.13% less feed than NSC during 1-20 weeks. Survivability of IDC up to 0-8, 1-23 and 24-75 weeks of age were found 97.25, 94.90 and 95.24%, respectively. The study reveal that IDC had relatively lower adult weight and consumed less feed without affecting egg production compared to NSC under intensive management condition and could be exploited its potentiality for development of mini layer under semi-scavenging system of Bangladesh.Bang.

Data were collected from a nucleus flock of Nageswari ducks that have been maintained from day old to 72 weeks of age at AI center, Bangladesh Agricultural University, Mymensingh, from May 2015 to October 2016. Irrespective of sex, the average live weight of ducklings at day old, 1st, 3rd, 5th, 7thand 9thweeks of age were observed to be 38.85±1.40, 99.06±2.93, 373.29±8.73, 650.31±11.26, 867.74±11.79 and 1076.11±16.34 g, respectively. There was a steady increasing trend observed in live weights for both drakes and ducks from 17thto 72 weeks of age. The average age of sexual maturity and weight were found 130±1.83 days and 1400.84±12.68g respectively. The average egg weight and annual egg production were 58.20±1.50g and 204.23±14.19 no’s, respectively. Hen day egg production was found 55.67±2.74% while the peak production was observed at 26th week of age. The estimated mean egg mass production (g/b/day), feed intake(g) during laying, feed conversion efficiency and performance efficiency index of Nageswari duck were 32.40±2.29, 154.85±2.27, 4.63±0.21 and 20.92±1.37, respectively in Nageswari duck. The external egg quality characteristics like shape index, egg breaking strength, shell thickness and membrane thickness were observed to be 74.59±0.61, 2.00±0.03 kg/cm2, 3.99±0.06 mm and 0.50 ± 0.02 mm respectively whereas, internal quality attributes such as albumen index, yolk index, yolk color score and Haugh unit were 8.89±0.29, 34.36±0.61, 8.42±0.28 and 86.29±1.06, respectively. In conclusion, the studied parameters of Nageswari duck provided some breed specific baseline information and year round actual production potentials of this genetic resource under intensive management condition that could be utilized for future conservation and breeding programs in Bangladesh.Bang.

The study was conducted with attempts to determine the effects of autosomal dwarf (adw) gene introgression from Indigenous dwarf chicken (IDC) to White Leghorn (WLH) and Fayoumi (Fay) on growth and meat yield characteristics. Experiment was carried out at the Poultry Farm of Bangladesh Agricultural University (BAU), Mymensingh for a period of 28 months from March 2013 to June 2015 under intensive management condition. In this study, the di-allele crossing between WLH, Fay and IDC produced 4 up-graded chickens viz. IDC♂ × WLH♀, WLH♂ × IDC♀, IDC♂ × Fay♀ and Fay♂ × IDC♀. The up-graded F1 generations were mated intersex to access their productivity. The up-graded F1 generations were mated intersex to access their productivity. Pre-slaughter live weight of birds significantly (P<0.001) varied by genotype, sex and genotype × sex interaction. Percentage of thigh meat, drumstick meat, dark and total meat weights was significantly influenced by genotype. Although meat yield parameters of male birds in relation to live weight were found higher than their female birds, some parameters like breast meat, liver, giblet and total meat yield were found higher in female birds than that of male birds of all genotypes. However, meat yield parameters like percentage of thigh, drumstick and total meat yield were the highest in IDC♂ × Fay♀ and Fay♂ × IDC♀ and the lowest in IDC♂ × WLH♀. From the above findings, Fayoumi mediated dwarf genotypes showed better meat yield characteristics than Leghorn mediated dwarf genotypes.

Variant Strain

Infectious bronchitis of chickens (IBC) is a highly contagious disease characterized by damage to the respiratory tract. Adult chickens exhibit respiratory symptoms, a 10-50% decrease in egg production, discoloration of the eggshell, deformation of the shell, and a deterioration in the marketability and breeding quality of eggs. The circulation of variant strains in poultry farms of the Russian Federation causes a significant decrease in egg production and the quality of the eggs obtained, causing significant economic damage to industrial poultry farming. The study aimed to presents materials and methods for the industrial and efficient use of live-vaccines against infectious bronchitis of hens from a variant strain. After the use of a live vaccine against infectious bronchitis of chickens from a variant strain, the development, live weight of chickens, and feed conversion during the rearing period were within the standard parameters. in present study, the safety for the growing period with a planned 97.6% was 98.8-98.9%. The uniformity of the herds when transferred to hen - hen was 94-95%. When carrying out immunoprophylaxis of IBS, local immunity is important, which can be ensured using a live spray vaccine - a method starting from the day old. When establishing circulation in the economy of variant strains of IBC virus, it is necessary to introduce vaccination against the variant strain into the scheme of treatment and preventive measures. The research results allow us to conclude that, for the effective prevention of chicken infectious bronchitis, immunization against IBS from variant strains should be introduced into the vaccine prevention scheme.

In this study, it was investigated the effect of clove oil supplementation at increasing levels into laying hens’ diets on performance, egg quality traits, some blood parameters and yolk TBARS (Thiobarbituric Acid Reagent) values. For this purpose 96 Lohman white laying hens, 28 weeks of age, were divided into four treatment groups. Control group was fed with basal diet (C) and treatment groups were fed with diets formed by addition of clove oil at 50 ppm (CO1), 100 ppm (CO2) and 150 ppm (CO3), respectively. During the trial, feed and water were given as ad-libitum, and poultry house was illuminated for 17 hours. Experiment lasted for 13 weeks. Addition clove oil at increasing rates into diet did not affect the live weight. The data analysed as polynomial showed that supplementation of clove oil into layer diet linearly improved feed conversion ratio and increased the egg production. But, daily feed consumption, egg weight, damaged egg ratio and egg quality parameters were not affected by treatments. Serum parameters such as triglyceride, glucose, aspartate aminotransferase, alanine aminotransferase and calcium were not affected by the clove oil supplementation. TBARS values in C, CO1, and CO2 were found higher than the CO3 group fed with diet including 150 ppm clove oil. In conclusion, clove oil at 150 ppm level in diets of laying hens could be used due to extend the egg shelf life and to decline serum cholesterol content.

Abstract This study was conducted to evaluate the effects of corn protein concentrate (CPC) levels in the diets on laying performance, and egg quality of laying hens. A total of 180 64-wk-old laying hens (2.05 kg ± 0.19 kg of live weight) were randomly assigned to 36 cages (5 birds/cage) with separate feeders, including 6 dietary treatments. Birds were fed 1 of 6 experimental diets containing CPC at different levels (0, 0.5, 1.0, 1.5, 2.0 or 2.5%) for 10 weeks. Diets were isocaloric (2850 Mcal/kg) and isonitrogenous (CP, 15.0%), having similar digestible amino acid profile. Hens were weighed at the beginning and at the end of the experiment to determine BW change. Egg production, feed consumption and egg weight were recorded daily, while egg quality variables were evaluated every 14 days. Data were analyzed using the general linear model procedure of SAS in a complete randomized design. The cage was considered the experimental unit. Linear and quadratic effects of treatment were used for mean separation and significance was declared at P ≤ 0.05. Hens fed CPC maintained BW and gain at an increased rate (Quadraic: P &lt; 0.01). Feed intake increased as CPC increased in the diet (Lineal and quadratic: P &lt; 0.01). Egg production, mass and weight were increased as CPC increased in the diet (Quadraic: P &lt; 0.01). Feed conversion rate was improved as CPC increased in the diet (Lineal and Quadraic: P &lt; 0.02). Shell thickness and breaking strength tended to linearly increased as CPC increased in the diet (P &lt; 0.06). Albumen height and Haugh unit were not altered by dietary treatment (P &gt; 0.25). Yolk color was increased as CPC increased in the diet (P &lt; 0.01). Results from this experiment suggest addition of up to 2.5% CPC in the diet enhances egg production and some parameters of egg quality.

SummaryEgg production performance of 571 local Ghanaian chickens and 107 SASSO T44 chickens kept under improved management conditions were analysed. Average egg weight, hen-day egg production and feed conversion ratio (FCR) were determined for the three experimental chicken ecotypes. Hen-day production was significantly (P&lt; 0.05) higher in the savannah local chicken ecotype than the forest ecotype and SASSO T44 chickens. Egg weights of local Ghanaian chickens compared favourably with values reported for local chickens in Africa. On the average, SASSO T44 had significantly (P&lt; 0.05) higher egg weights and feed intake compared with the local chicken ecotypes. The local chicken ecotypes on the other hand, had significantly (P&lt; 0.05) better feed conversion ratios than SASSO T44 chicken. Local Ghanaian chicken ecotypes have a more efficient FCR per every unit of egg produced compared with the control population. Low feed intake, good feed conversion ratios and adaptation to the environment are traits local chicken harbour which can be exploited in future breeding programmes to improve on chicken meat and egg production in Ghana. Ghanaian local chickens could thus be a valuable genetic resource for the development of an efficient egg production chicken breed adaptable to the humid tropical climates.

The effects of oral administration of seven mL soybeen oil/kg live weight (LW) on the performance and carcass characteristics of native ram. In a 162 days feeding trial, 18 growing native rams (9.4 ± 1.2 kg BW and 176 ± 5.6 d of age) were randomly allocated to three treatments (T0, control, T1, monthly infusion of oil and T2, fortnightly oil infusion group) with six replicates in each. All animals were fed roughage (Ad lib urea molasses straw, UMS) and concentrate (1.5% of body weight). After feeding and digestion trial, five animals in each group were slaughtered for carcass characteristics. During the trial, growth rate was significantly (P<0.05) influenced by the treatments (T0, T1 and T2 were 69.5, 83.8 and 69.8 g/d). On average, T1 group showed 20.7% higher growth over the control and T1. The protozoa populations were reduced by 74% and 84% in T1 and T2 than that of control group. Consequently, the ammonia concentration in the rumen fluid of T1 group was significantly (P<0.05) lower (177 mg/L) than that of T2 (208.0 mg/L) and control (245.0 mg/L) group, respectively. Consequently, Feed conversion ratio (FCR) was better (8.0) belonged to T1 than that of control (8.6) and T2 (9.3). Interestingly, fat deposition was inclined significantly (P<0.05) in T2 group than that of T1 and control, which is unacceptable to the customers. Meanwhile, fortnightly oil treatment (T2) is not recommended, but further study is required with different intervals. DOI: http://dx.doi.org/10.3329/bvet.v28i1.8810   Bangl. vet. 2011.

This study was carried out to investigate the effect of different body weight groups (light (L) = 1 400–1 500; medium (M) = 1 500–1 600 and heavy (H) = 1 600 < g) on performance and egg quality traits of Lohmann hens, 24 weeks of age, in different laying periods. A total of 288 Lohmann White layers were allocated randomly to three groups with respect to live weight, each consisting of 24 replicated cages as subgroups, comprising four hens. The study period lasting for 60 weeks was investigated as four different age periods (first period = 24–40 weeks; second period = 40–54 weeks; third period = 54–68 weeks; fourth period = 68–84 weeks). Differences in the initial live weight at the beginning of experiment among the groups continued to the end of experimental period. Considering the egg production, differences among the groups were not significant (<I>P</I> > 0.05) during the experimental period. Egg weight was determined to be lower in the group with low body weight (64.58 g) than in medium (64.97 g) and heavy hen groups (66.30 g). Differences in feed intake and feed conversion ratio among the groups were found significant, and the mean values were 123.93, 127.48 and 130.67 for feed consumption (g/day); 2.23, 2.28 and 2.27 for feed conversion ratio. Except for the feed conversion ratio, the effect of weight groups by age period interaction on performance parameters was significant (<I>P</I> < 0.01). The effects of body weight on shell strength, shell thickness and yolk index were not significant during the experimental period. However, different body weight groups significantly affected shape index, yolk colour, albumen index and Haugh unit parameters. Shell strength, yolk colour and yolk index values were affected by weight groups by age period interaction. In conclusion, Lohmann White hens in the light group in a uniform flock had higher egg production and lower feed conversion ratio values than those of other weight groups.

Inclusion Level

The study was conducted to evaluate an appropriate inclusion level of white-flowered semi-leafless green spring peas in diets for laying hens. Egg production and egg quality variables (specific weight, Haugh unit, shell strenght) were determined with 576 hens in a 52-week feeding experiment, which comprised of three feeding phases. The hens were offered one of the four cereal and soybean meal (SBM) based experimental diets. Peas were tested in proportions of 0, 100, 200 or 300 g kg-1 in the diet. Pea inclusion had no effects on production performance, feed consumption or feed conversion ratio (FCR) of the hens during the entire trial. The pea inclusion impaired FCR during the second feeding phase (p < 0.05) and increased birds’ live weight in a linear manner during the second and the third feeding phases (p < 0.05). Pea inclusion had no effects on egg quality. It can be concluded that at least 300 g kg-1 of the studied peas can be used in the diets of laying hens without negative effects on production performance or egg quality.
