Not AvailableEllagic acid (EA), a polyphenoloic constituent in fruits and nuts, has been shown to have antioxidant and antiapoptotic properties. The aim of this study was to investigate the effect of dietary EA supplementation on semen quality parameters in chickens. Forty roosters (Dahlem Red breed), 28 weeks of age, were randomly assigned to four groups and fed diets containing EA at 0, 25, 50, or 75 mg/kg for 8 weeks. Semen was evaluated for volume, appearance, individual motility, sperm concentration, 3 -[4,5 -dimethylthiazol -2 -yl] -2,5-diphenyltetrazolium bromide (MTT) dye reduction test, and live, dead and abnormal sperm counts. The seminal plasma was separated and evaluated for protein, alkaline phosphatase, and lipid peroxidation. At the end of the experiment, blood from individual birds was collected, and serum was separated and evaluated for superoxide dismutase activity, lipid peroxidation, and ferric-reducing ability of plasma. Supplementation with EA had no effect (P > 0.05) on gross semen parameters. Seminal plasma protein and lipid peroxidation were different (P<0.01) between the treatment groups. The group fedEAat 75 mg/kg had high (P<0.01) seminal plasma lipid peroxidation and lower (P < 0.05) serum superoxide dismutase activity. In conclusion, dietary supplementation of EA in chickens had no effect on the gross semen qualities and increased lipid peroxidation in seminal plasma.ICAR-DP

Not AvailableThe mRNA expression profiles of Hsp-90 alpha, Hsp-90 beta and Hsp-60 were evaluated in coloured broiler chickens, that is, Punjab broiler-2 (PB-2) and naked neck (NN), exposed to 2°C increased incubation temperature for 3 h each on 16th, 17th and 18th days of incubation. Another set of eggs were incubated at normal conditions that were utilized as control. A total of 432 chicks, 216 in each breed (PB-2; NN) and treatment (heat exposed; normal), randomly distributed were reared at high ambient temperatures (32–45°C) during summer in battery brooders. Birds were sacrificed on 0 and 28th days post-hatch and different tissues (heart, liver, muscle, spleen and bursa) were collected to assess the mRNA expression. Heat exposure during incubation significantly (P ≤ .05) influenced the expression of Hsp-90 alpha in spleen of day old; in heart, liver and spleen at 28 days in PB-2 chicken. Hsp - 90 alpha mRNA expression was not significant among the tissues at different ages in NN chicken. Hsp-90 beta did not show any significant variations in gene expression across the tissues at both the age groups either in NN or in PB-2 chicken. Heat exposure had significant effect in the expression patterns of Hsp-60 at 28 days in heart, liver and spleen in PB-2 chicken. The mRNA expression of all the three genes significantly (P ≤ .05) varied in different tissues across the age groups in both PB-2 and NN chickens. The study concluded that thermal adaptation during the embryonic stage to higher incubation temperature reduced Hsp gene expression in different tissues in postnatal life during high ambient temperature which might result in increased heat tolerance capacity of the broiler chickens.ICAR-NICR

Not AvailableThe present study was carried out to record the status of different blood and serum biochemical parameters of White Leghorn chicken at high ambient temperature. A total of 18 birds (9 birds of each sex) of 20 weeks age were used in the study. The heterophil: lymphocyte (H:L) ratio indicated that the birds were experiencing heat stress due to high ambient temperature. Significant difference was observed between the sexes in haemoglobin, total erythrocyte count, heterophils, H:L ratio, calcium and lipid peroxidation levels. Results of this study revealed that high ambient temperature induces stress that affects the sexes differently in chicken as evident from their blood profile.ICAR-DP

AICRP-PB & PSP Annual Report (2018-19)

The ICAR-Directorate of Poultry Research is a premier organization under the aegis of Indian Council of Agricultural Research mandated to conduct the research in frontier areas of poultry production in the country. The Directorate is coordinating and monitoring 12 centres of All India coordinated Research Project on Poultry Breeding and 12 centres of Poultry Seed Project. I feel privileged to present the Annual Report of AICRP on Poultry Breeding and PSP for the year 2018-19

Not AvailableAICRP on Poultry Breeding is one of the successful projects being operated at twelve centres viz. KVASU, Mannuthy; AAU, Anand; KVAFSU, Bengaluru; GADVASU, Ludhiana; OUAT, Bhubaneswar; ICAR-CARI, Izatnagar; ICAR RC for NEH Region, Agartala; NDVSU, Jabalpur; AAU, Guwahati; BAU, Ranchi; MPUAT, Udaipur; and CSKHPKVV, Palampur. The main objectives of the proect are development of location specific chicken varieties; conservation, improvement, characterization and application of local native, elite layer and broiler ermplasm development of packae of practices for village poultry and entrepreneurships in rural, tribal and backard areas In addition A annuth and AA Anand centres to maintain two elite layer germplasm (IWN and IWP). KVAFSU, Bengaluru, and GADVASU, Ludhiana, OUAT, Bhubaneswar, ICAR-CARI, Izatnagar to maintain a total of four (two by each centre) elite broiler germplasm (PB-1, PB-2, CSML and CSFL).Not Availabl

Not AvailableThe aim of the study was to optimize the nutrient requirement for Dahlem Red (DR) birds. For the purpose, five diets were formulated i.e., one basal diet (BD) with optimum (100%) nutrients, two diets with lower (97.5 % and 95%) and two diets with higher (102.5% and 105%) nutrients to the BD for conducting the feeding trial in DR layers. During the experiment-I, a total of 240 number of DR layers (31 weeks) were selected and divided into 5 groups, each having 8 replicates and each replicate had 5 birds. The experiment was continued up to 50 weeks. The egg production was higher (P<0.05) among the birds fed diet contained higher nutrient density (102.5% and 105%) compared to those birds fed lower nutrient density diets (97.5 % and 95%) during the 31-38 weeks. Similarly, feed efficiency was better (P<0.05) among the groups fed diet contained higher nutrient density compared to those groups fed lower nutrient density diets during the 35-38 weeks. However, hatchability, egg weight, stress and immune parameters did not differ among the various dietary groups throughout the experimental period. During the experiment-II, a total of 45 DR roosters (39 weeks) were randomly divided into five groups in individual cages in an open-sided house. An experimental breeder male diet was prepared to contain optimum (100%), lower (95% and 97.5%) and higher (102.5% and 105%) nutrient density. Semen from all the roosters was collected at 4th and 8th week and evaluated for different parameters. Semen quality parameters i.e., volume, motility, sperm concentration and, live and abnormal sperms among the different dietary groups did not differ in the present experiment. Basing on the results, it is concluded that the diet with 102.5% nutrients probably the more remunerative as the higher egg production and better feed efficiency was evident. Further, altering the nutrient in the diets up to 5% higher or lower to the basal breeder diet did not influence the semen quality parametersNot Availabl
