A study was conducted on the performance of exotic laying birds under scavenging systems at Sharishabari, Jamalpur during July, 2005 to June, 2006. For this purpose four exotic (three female and one male) and three local birds were provided to the six landless and six marginal cooperator farmers whereas six landless and six marginal non-cooperator farmers were considered as control. The average mortality in exotic chicken was 55% in case of local breed. The body and egg weight of exotic birds (1.65 kg and 56 gm respectively) were higher than the local breed (1.00 kg and 54 gm respectively). The average egg production per year was found to higher in exotic (84) than the local breed (62). But the benefit cost ration of exotic was found to be lower (1.36) than the local breed (1.46).

The improvement of productivity of indigenous chicken is a long desire in the country. Present research is a part of the long-term selection program being undertaken to evaluate the carcass characteristics and expected response to selection of second generation (G2) of indigenous chicken under intensive management in Bangladesh. A total of 1643-day-old chicks comprising of 3 types of chicken namely Naked Neck (NN), Hilly (H) and Non-descript Desi (ND) were hatched in a two batches for this study. In second generation (G2), selection was practiced at 3 (three) stages of birds life, firstly and secondly at 8 and at 16 weeks of age, selection was performed on the basis of breeding value for 8 and 16 week body weight. Thirdly, at 40-week of age, on the basis of an index comprising the parameters of age at sexual maturity (ASM), body weight (BW), egg production (EP) and egg weight (EW). Improvement target of egg weight was to increase by 1g and improvement target of egg production rate was to increase by 2 % per generation. The main target was the mean body weight in H, ND and NN chicken has to be gone up from the initial eight-week body weight of 375, 342 and 331g to 500 g at eight weeks of age. At 8, 10 and 12 weeks of age, six birds from each genotype were slaughtered to analyze the meat yield traits. Slaughter data were analyzed in a 3(genotype)×3(slaughter age) factorial arrangement in CRD by General Linear Model (GLM) Univariate Procedure in SPSS Computer Program. Genotype and slaughter age had significant effect (p<0.001) on dressing percentage. Body weight at 8 weeks of age was expected to improve by 51.21 vs. 24.03; 37.74 vs. 15.47 and 26.26 vs. 9.65g; respectively for ND, H and NN males and females. In terms of body weight H genotype was superior and NN genotype was for dressing percentage. As a result of selection; EP, BW increased and ASM reduced in second generation than that of the foundation stock.Asian J. Med. Biol. Res. March 2017, 3(1): 66-71

Abstract The aim of the study was to determine the usefulness of two protein concentrates composed of rapeseed meal and new cultivars of narrow-leaved and yellow lupine, peas in laying hen diets and their influence on birds’ performance and egg characteristics. The experiment was conducted with 180 layers kept in individual cages. The birds were randomly assigned to three treatments, with 60 hens in each and during the period of 17 weeks, they were fed diets: I - containing soybean meal as a protein source, II - containing protein concentrates composed of mixture of lupines, peas (19.48% of diet) and rapeseed meal, III - containing protein concentrates composed of a mixture of lupines and peas (27.68% of diet). The body weight, laying rate, egg weight, feed intake and feed conversion ratio (FCR) and egg characteristics were registered. After 9 weeks of experiment, a decrease of laying rate was recorded in treatment III. The mean value of laying rate for 17 weeks amounted to 82.7 (I), 82.5 (II) and 75.9% (III) (P<0.01). The egg weight was diversified already after 4 weeks of egg production and averaged 57.9 (I), 55.9 (II) and 54.9 g (III) (P<0.05). Feed intake amounted to 108 (I), 111 (II) and 104 g per hen/day (III), and FCR was 2.05, 3.17 and 2.23 kg/kg egg weight, respectively. As to egg characteristics, increases of white index (P<0.05), Haugh unit score and yolk colour in treatment III were observed but egg shell thickness was found significantly reduced. In conclusion, the use of about 27.68% of legume seed in laying hen diet affected negatively performance results but about 19.48% of these seeds and 8% rapeseed meal in diets could be accepted as a soybean meal substitute.

Selection is one of the vital tools for improving the indigenous chicken genetic resources. A total of 1585-day-old chicks comprising of 3 types of chicken namely Naked Neck (NN), Hilly (H) and Non-descript Deshi (ND) were hatched for this study to form foundation stock. Improvement target of egg weight was to increase by 1g and improvement target of egg production rate was to increase by 2 % per generation. In foundation stock, selection was practiced at 40-week of age, on the basis of an index comprising the parameters of age at first egg (ASM), body weight(BW), egg production(EP) and egg weight(EW). Data were analyzed in CRD by General Linear Model (GLM) Univariate Procedure. Significantly highest fertility (82.71%) and hatchability (82.20%) were found in ND genotype. Significantly (P<0.001) highest body weight of day-old chicks and daily weight gain was found in H genotype than other two genotypes. There was a non-significant (P>0.05) variation in FCR among the native chicken genotypes. NN genotype (3.46%) had non-significantly (?2 = 3.62; P > 0.05) higher chick mortality than ND (1.63%) and H (2.11%) at brooding period (0-4 weeks). Significantly (P<0.01) higher dressing percentage was found in NN (64.58) genotype than ND (60.26) and H (61.70) genotypes. Non-significantly higher egg production in selected group was found in H (70) genotype than ND (68) and NN (67) genotypes. Significantly (P<0.001) highest shape index and Haugh unit were found in H and ND genotypes, respectively. As a result of selection, egg production is expected to improve by 0.562, 0.932 and 0.755%, respectively for ND, H and NN genotypes. In terms of reproductive traits ND was superior, in terms of productive traits H genotype was superior and in terms of dressing percentage and breaking strength NN genotype was superior. These findings of the study also give an impetus for continuing the research for more generations to fulfill the objectives of the long-term programme.Asian J. Med. Biol. Res.

Indian White Leghorn strain-IWK has been improved for higher egg weight as well as number over last twelve generations at ICAR-Directorate of Poultry Research, Hyderabad. The data collected on various economic traits of egg production were analyzed using REML approach of animal model. Current study showed that the heritability estimate of body weight, age at sexual maturity (ASM), egg numbers and egg weight was moderate to high, low to moderate, low and high, respectively. The body weight was positively correlated with egg weight but negatively correlated with egg numbers. The body weight at 16 and 20 weeks were negatively correlated with ASM and were very important for achieving early ASM. ASM was negatively correlated with egg numbers. The egg weight regressed as the egg number increased. The part period egg production EP52 was highly correlated with EP64; therefore EP52 can be used for selecting parents for higher egg number instead of EP64.

Abstract. This study estimates the additive and non-additive variances for egg production and body weight traits of two lines of quails from a long-term selection with the help of the REML method. For the body weight of 42-day-old females (BW42f) and males (BW42m), a total of 7,934 records for line 1 and 7,214 records for line 2 from 21 generations were used in our analyses. Additionally, 1,717 records of females from line 1 and 1,671 records of females from line 2 contained information on their egg production at an age of 42 to 200 days (EN200), on the average egg weight for the first 11 weeks of their laying season (EW1), on the average egg weight from weeks 12 to 23 (EW2), and on their body weight at an age of 200 days (BW200f). A multivariate additive animal model and one-trait dominance models, which include the inbreeding coefficients as covariates, were fitted to the data. The estimates of the heritability gained from our dominance models were smaller than those from the additive model. For line 1, the heritability values decreased for EN200 from 0.35 to 0.32, for EW1 from 0.66 to 0.56, for BW200f from 0.42 to 0.38, and for BW200m from 0.51 to 0.49, respectively. For the first line, the respective ratio (d2) of the dominance variance to the phenotypic variance for EN200, EW1, BW200f and BW200m was 0.08, 0.22, 0.09 and 0.21, and the values for the second line were 0.12, 0.06, 0.001 and 0.23.

Data on the Ife Breed of the indigenous chicken and the Apollo, an imported commercial egg strain were analysed for effect of breed, time and generation of hatch, body weight at various ages, and age at sexual maturity on egg weight and rate of egg production to eight months. There were highly significant generation and breed differences, with a mean of 116 eggs for the Ife Breed compared to 106 for the Apollo over two generations. Other factors that significantly affected egg production were body weight and age at sexual maturity, and mature egg weight. Mean pullet year egg weight showed breed and hatch differences and were significantly affected by body weight and age at sexual maturity. Mean egg weight for the Ife Breed was 32.3 compared to 48.7 for the Apollo.

A total of 887 ducklings of BLRI-1 duck genotype and 352 ducklings of BLRI-2 duck genotype were studied to measure productive and reproductive performances under intensive management. Data were recorded on body weight, egg production, egg weight, fertility, embryonic mortality, hatchability, feed intake, age at sexual maturity, body weight at maturity and egg weight at maturity. The fertility rate in BLRI-1duck was significantly (p<0.01) higher than that of BLRI-2 duck, while hatchability of BLRI-2 duck on fertile eggs were significantly (p<0.05) better compared to BLRI-1 duck. The embryonic mortality was significantly (p<0.01) higher in BLRI-2 duck than BLRI-1 duck. Duckling weight was influenced by egg weight (p<0.05) but difference in duckling: egg ratio was not significant (p>0.05). Hatching weight, 4th week and 12th week of age were significant (p<0.05) influent while the body weight of ducks at 8th week did not differ significantly (p>0.05) for BLRI-1 and BLRI-2 ducks, respectively. The least squares mean for age at sexual maturity were 158 days and 151.75 days, respectively for BLRI-1 and BLRI-2 ducks (p<0.05). BLRI-1 duck started to lay eggs almost one week late compared to BLRI-2 duck. Duck weight at sexual maturity, egg weight at first lay and egg production did not have significant (p>0.05) difference between genotypes. It may be concluded that BLRI-2 duck genotype is superior in terms of hatchability and age at sexual maturity to BLRI-1 duck genotype.

This study focused on investigating the reproductive performance of Nigerian indigenous chickens and their crosses with Marshall. The genotypes were normal-feathered (Nn), frizzle-feathered (Ff) and naked neck (Na) chickens, while the crossbreds with Marshall (M) breed were MNn, MFf and MNa respectively (Marshall being the sire while the indigenous are dams). Data were taken on; weekly egg production, weight at first egg and age at first egg. Genotype significantly (P<0.05) influenced egg production traits. Egg weight ranged from 23.71±1.06g to 26.13±0.94g for indigenous purebreds and 39.75±0.75g to 48.06±0.57g for crossbreds. Age at first egg were 165.63±0.61 days (Nn), 170.60±0.75 days (Na) and 173.57±0.52 days (Ff), 188.71±1.67 days (MNn), 187.50±3.16 days (MNa) and 185.25±5.44 days (MFf). Also, genotype significantly (P<0.05) influenced egg quality traits. Heritability for first egg production traits were 0.37 (Nm), 0.16 (Na) and 0.66 (Fz) while heritability estimates for egg quality trait (haugh unit) were 0.14, 0.07 and 0.08 for Nm, Na and Fz birds, respectively The crossbreds performed better than the indigenous purebreds in egg production traits. The Nigerian indigenous chicken can therefore be improved upon for better egg production traits using the Marshall breed.

Body Weights

Forty 76 weeks old Olympia Black layers were randomly selected, individually caged and intensively reared for a period of 16 weeks to study the effect of body weight on some egg production traits. The analysis of variance revealed significant effect of body weight on production traits investigated (P<0.01) except egg index (P>0.05). The correlation analysis showed that the body weight was positively and non-significantly (P>0.05) correlated with egg length, egg breadth, she'll weight, yolk weight, albumen weight, she'll thickness and significantly with egg weight (P<0.01) and negatively with egg index (r = 0.016). The second-degree (quadratic) equations for estimates of optimum 76 week body weights suggested 1.271 to 1.801 as required body weight range in kilograms for satisfactory performance. The body weight range at this age is attainable through breeding, good feeding and other management practices.
