Genetic diversity is one of the useful tools to select appropriate lines for hybridization. Twenty short-statured maize inbred lines were taken for present study, which were collected from CIMMYT India and Mexico through Plant Breeding Division, Bangladesh Agricultural Research Institute (BARI), Gazipur. This experiment was conducted from November 2015 to April 2016 to identify parental lines to produce single cross short statured maize hybrids. From the genetic diversity studies, the importance of both additive and non-additive gene actions for the expression of yield and yield contributing characters were found. Values of vector I and II revealed that both the vectors had positive values for date of silking, plant height, rows/cob, grains/row and yield. These results indicated that these five characters had highest contribution towards divergence. Based on the relat

The present study was undertaken to assess feeding effect on productive and reproductive performances of pre-natal and post-natal Red Chittagong Cattle （RCC） cows under on-station condition. A total of 16 pregnant RCC cows having pregnancy 6-7 months and between 1-3 parities was selected for the study and was allocated randomly into four dietary treatment groups. There are four type diets, i.e., To （standard diet according to National Research Council （NRC）, 1995）, T1 （5% below standard diet）, T2 （5% above standard diet）, T3 （10% above standard diet） and a control treatment T4 （maintained as farm practice）. The energy and protein requirements of experimental cows were determined as per standard developed by NRC. The results revealed that crude protein （CP） and metabolizable energy （ME, MJ/day） requirements among cows of different dietary groups were not significantly different, although CP requirements between T1 and T3 differed significantly. Total dry mater （DM） and ME intake differed significantly （P 〈 0.001） among cows of different dietary groups, but DM intake was significantly lower for cows in farm practice group Z4 compared to the cows of other dietary groups. The total CP intake had no significant variation （P 〉 0.05） among cows of all dietary groups, but CP intake from roughage varied significantly （P 〈 0.001）. Final live weight and total live weight gain had no significant variation for cows of all groups, but there were significant （P 〈 0.05） variation for daily weight gain. Daily weight gain of cows for first four dietary groups were significantly （P 〈 0.05） higher than cows of farm practice groups T4. Weight of calf from birth to 90 days and daily weight gain calves under different dietary groups showed that there were no significant （P 〉 0.05） variation of calf birth weights for all dietary groups, although lower birth weight was found in farm practice groups T4. Gestation length and postpartum heat period of cows of different dietary treatment groups

多彩的混乱。“在粘土遍布的亚马逊盆地,长尾小鹦鹉和金刚鹦鹉会吃粘土来中和它们胃里的毒素。要到达厄瓜多尔的叶苏尼国家公园,需要在地方转车,并在上游乘3个小时的船才能到达。经过3天的等待,我们花了好几个小时才看到数百只鹦鹉降落在森林。看着它们,并且听着它们震耳欲聋的叫声,我永生难忘。鸟儿飞向空中时,我使用慢速快门捕捉它们的运动轨迹。”
