An epidemiologic study was conducted on 581 dairy cows (indigenous and its crosses 371, exotic crosses 210) of 4 government establishments to find prevalence of udder and teat diseases and their association with udder and teat characteristic, milk yield and milk flow rate in dairy cows. Mastitis (25.5%) was most common disease followed by udder skin diseases (15.0%) and teat diseases (12.6%). P...
Salicylic acid (SA) a naturally occurring plant hormone is an essential signal molecule recognized to have diverse effects on biotic and abiotic stress tolerance. The present study was planned to investigate the role of SA in salt tolerance of maize. Experiment was conducted to study the SA induce physiological and biochemical changes in two genotypes of maize viz., Sahiwal-2002 and EV-20 in th...
In order to develop specific genetic markers and determine the genetic diversity of Bangladeshi native cattle (Pabna, Red Chittagong) and exotic breeds (Sahiwal), randomly amplified polymorphic DNA (RAPD) analysis was performed using 12 primers. Genomic DNA was extracted from 20 cattle (local and exotic) blood samples and extracted DNA was observed by gel electrophoresis. Among the random prime...
Physical characteristics of eight maize varieties /lines (EV-6089, Sahiwal-2002, Golden, 34N43, EV-1098, Sultan, China-1, EV-20), seven yellow and one white, obtained from Maize and Millet Research Institute, Yousaf Wala, Sahiwal, Punjab, Pakistan, in free choice test, were correlated with biological parameters of life history of Sitotroga cerealella (Oliv.) (Gelechiidae: Lepidoptera). S. cerea...
Received: Revised: Accepted: April 22, 2013 July 30, 2013 July 31, 2013 The present study was aimed to investigate the association of scrotal circumference (SC) with sperm production and semen quality in Sahiwal bulls. Mature semen donor bulls (n=76), 3 to 5 years old, were divided into three groups according to SC: GI, GII, and GIII with 28-30, 31-35, and >35 cm, respectively. Semen was collec...
The production performance of multiparous lactating Sahiwal cows (n = 24) was evaluated according to both milking frequency and method. Selected animals were randomly divided into four groups containing six animals each under a completely randomized design. Cows in groups A & B were milked by the hand milking method three times per day, respectively. Similarly, cows in groups C & D were milked ...
Study comprising seventy two cattle of three breeds/strain viz. Hardhenu crossbred strain, Hariana and Sahiwal breeds were carried out to evaluate the differences in hematological parameters. Each group consisted of 24 animals of different age groups i.e. 0-1 year, 1-2 year, 2-3 year and >3 year. The various hematological parameters i.e. hemoglobin (Hb), total leucocyte count (TLC), differentia...
Production traits of 60 indigenous (Desi), 20 Friesian × Desi and 20 Sahiwal × Desi cows were recorded in six char villages of Sariakandi upazila (Sub-district) of Bogra district. The mean (± SD) daily milk yields were 1.7 ± 0.6, 6.3 ± 1.2 and 5.1 ± 1.0 litres, respectively. The lactation lengths, ages at puberty, gestation lengths, calving intervals, numbers of services per conception, interva...
