This study was conducted to investigate the effect of egg size, age of hen and storage period of eggs before incubation on fertility, hatchability, embryo mortality and chick malformations in Japanese quail (Coturnix coturnix japonica). The study was carried out in quail farm located at Tanah Merah, Kelantan. Totally 1441 eggs of quail were set into the incubator by applying 9 treatments groups: 3 groups for egg size (6-7 g, 8-9 g and 10-11 g), 3 groups for hen age (≥ 3 -<5 month, ≥5 -<8 month and ≥8 -<10 month) and 3 groups for egg storage period (≥ 4 -≤6 days, ≥7 -≤9 days and ≥10 -≤14 days). Records on fertility, hatchability, embryo mortality and chick malformations were taken from each hatch. Analysis of variance (ANOVA) revealed that the egg size had highly significant (P< 0.01) effect on hatchability and embryo mortality in quails and was not found to be significant (P>0.05) on fertility and chick malformations. The age of hen had insignificant (P>0.05) effect on every aspect except fertility. Storage period had highly significant (P<0.01) effect on fertility, hatchability and embryo mortality rate. Results from this study concluded that heavy egg weight (10-11 g), middle aged hen (≥5 -<8 month) and shortest storage period (≥4 -<6 days) gave the best hatching performances.
The Pabna is one of the potential local cattle breeds in Bangladesh regarding milk production and its nutritive quality. The aim of the study was to know the effect of lactation length, parity and management on production performance and nutritional/physiochemical composition of the milk of local Pabna cows. Besides the regular milking, 15 days’ interval test day milking was recorded from 12 local Pabna cows with different lactation period (up to fifth month of calving) from BLRI Regional Station, Baghabari during January-September, 2018. In addition, 12 and 16 milk samples (200 ml/sample) were collected from the cows raised at BLRI Regional Station and the community of Dairy Development Research Project at Bera, Pabna district during June, 2018, respectively. Data were analyzed in an ANOVA of Completely Randomized Design and independent sample t-test, respectively, using SAS version 9.1.3 (SAS Institute Inc., Cary, NC, USA) including Tukey’s HSD post hoc test to separate means. The average daily milk yield was significantly (p<0.05) higher during the first month (4.62 L) of lactation and the lowest value recorded at 5th month (3.50 L). Among the test days milking better yield observed at 15 days (4.79 L) of experimental lactation period (p<0.05). The effect of lactation stages and parity number had no significant variations (p>0.05) on nutrient compositions of local Pabna cows’ milk in both on-station and community. However, the overall characteristics of milk between on-station and community had significant differences on the composition of total solids (p<0.001), SNF (p<0.001), fat (p<0.01), and protein (p<0.05) where the highest values found as 14.81, 8.65, 6.17 and 3.53% at on-station, respectively. The first month of lactation observed as best milk producing period among the five months and the management system had positive association with milk composition of local Pabna cows.

There were 17 districts under Dhaka, Chottogram, Sylhet, Rajshahi, Khulna and Mymensingh divisions selected for this study on the basis of Turkey farming. The total 52 number of farmers interviewed to conduct this study. Turkey rearing is a profitable agricultural practice to meet the protein requirement in developing countries like Bangladesh. This is not only a source of protein but also a rich source of minerals and vitamins. The semi-intensive rearing of turkey requires low capital investment and labor cost. The main objectives of the study were to know the present status of feeding and rearing system, problems and prospects and benefit cost ratio of turkey rearing in Bangladesh. The information that collected from the respondents were age, education, main occupation, family members, training, annual income, number of turkey in each batch, name of strain, mortality rate, vaccination and medication practice, current situation of antibiotic and growth promoter use, use of footbath, use of disinfectant for spraying in inside and outside of the farm, percentage of antibiotic and feed additives withdrawal period before marketing, source of vaccine and medicine at farmer level, consultants of the farmers for vaccine and medicine specially antibiotic use, vaccination and medication cost in a batch. The average cost for production of one kg meat is BDT 231.177 and average market price of one kg meat was about BDT 452.34.
