Change in sex ratios for broiler chickens, has many economic benefits of the poultry industry. The gonads in chick embryo at an early stage have the potential to convert to both sexes (male and female). Sexual differentiation is due to aromatase expression in the left gonad in 5-6 days of the embryonic period and the production of estrogen from testosterone. Administration of aromatase inhibito...

The addition of ginger and milk powder rejected in the feed can improve work organs digestion. This research was conducted with aim knowing effect adding ration at different levels on internal organ profile broiler chickens. method used this study a completely randomized design factorial pattern 3 treatments (factor A) 4 B) using 2 replications for each replication or experimental unit containi...

Data from 645 normal rabbits were used as the basis of an investigation of the relation existing between body and organ weights. Actual and relative weights were correlated with both gross and net body weight. The results obtained varied with different classes of organs but it was found that, in general, there was an agreement between the form and degree of the correlation shown and the structu...

The gross and microscopic anatomy of the Cape fur seal heart, lung, liver, spleen, stomach, intestine and kidneys (n = 31 seals) is described. Absolute and relative size of organs from 30 male seals are presented, with histological examination conducted on 7 animals. The relationship between log body weight, log organ weight and age was investigated using linear regression. Twenty five animals ...

Arsenic hydrogen is a colorless gas. It enters the body through respiratory system, without irritating mucous membranes of upper tract. poison with primary hemolytic effect. In body, arsenic oxidized to and excreted from mainly kidneys intestines. The consequence rapid massive hemolysis anemia, hypoxia, damage parenchymal organs (kidneys, liver), nervous cardiovascular system. addition hemolysi...

to study the effects of used water in evapotranspiration, seed number per unit area and leaf relative water content on seed weight of canola (brassica napus l.), an experiment was conducted as a randomized complete block design, arranged in a split-plot under two conditions, i.e. supplemental irrigation and rainfed in 2005-7. two cultivars of canola (‘hyola401’ and ‘rgs003’) as subplots were gr...

the present research was conducted to analyze the genetic structure of egg quality traits in japanese quail. external and internal egg quality traits were assessed on 1706 eggs of laying japanese quail. eggs were collected for 4 days at the quaits 10 weeks of age. the investigated traits were analyzed through univariate as well as multivariate animal models employing restricted maximum likeliho...
