The treatments were as follows: T1: chicks hatched up to 486 hours, T2: 492 hours, T3: 498 hours, and T4: 504 hours, separated by sex, with the purpose of observing plasma protein levels, mainly globulin, as an immunological indicator up to day 21 of life. The variables considered were total proteins, albumin, and globulin in blood serum, and measurements were taken at three time points: on days 0, 10, and 21 of the chicks' lives, using the Spectrophotometry technique in the Chemistry Laboratory at ESPAM MFL. The results show non-significant differences (p-value 0.3284) for total proteins concerning sex and hatch hour. Similarly, albumin values do not show significant differences (p-value 0.6122) among the treatments, as well as for globulin (p-value 0.5384). It is concluded that the hatch windows do not affect plasma protein levels present in COBB 500 chicks from hatch to day 21 during rearing. |
