Coconut mite (Aceria guerreronis 'Keifer') has become a major threat to Indian coconut (Coçcos nucifera L.) cultivators and the processing industry. Chemical and biological control measures have proved to be costly, ineffective, and ecologically undesirable. Planting mite-resistant coconut cultivars is the most effective method of preventing yield loss and(More)
This experiment was conducted to evaluate the effect of Bacillus subtilis (BS) on broiler performance and health after intramuscular inoculation with E. coli and compare its effect with a growth promoter antibiotic. In a completely randomized design manner, 360 male Ross 308 chicks were divided into 6 treatments and 5 replicates of 12 chicks in each(More)
This study was conducted at high altitude (2100 m above sea level). A total of 208 d-old male broilers (Ross 308) were randomised across 16 floor pens and reared up to 42 d. A normal-protein diet (NPD) was formulated according to the National Research Council. A reduced-protein diet (RPD) was prepared with dietary protein reduced by 30 g/kg relative to that(More)
Early embryonic death of calves due to sub-fertility in cows is of great economic concern to dairy industry. Early pregnancy factor (EPF) is a secretory protein with pregnancy associated immunosuppressive properties. Rosette inhibition test (RIT) was used to detect EPF in inseminated dairy cows. Blood samples were collected at two intervals, 1-3 and 5-7(More)
This experiment was conducted using 192 day-old Ross 308 chicks, divided into 4 groups of 4 replicate consisting 48 birds. Group I was fed a control diet, Group II was fed control diet supplemented with 0.5 ppm T-2 toxin for 5 weeks, Group III was fed control diet supplemented with 8 × 10(8) cfu/mL of Mycoplasma gallisepticum, and group IV was fed control(More)
The insulin-like growth factor 1 (IGF-I) gene has been described in several studies as a candidate gene for growth.Thispreliminary study attempts to identify associations between growth traits and genetic polymorphisms at the 5’ flanking region IGF-I in Makui sheep. DNA samples from100Makuisheep,anindigenous Iranian breed,wereevaluated in the research.(More)
