The "cock-a-doodle-doo" crowing of roosters, which symbolizes the break of dawn in many cultures, is controlled by the circadian clock. When one rooster announces the break of dawn, others in the vicinity immediately follow. Chickens are highly social animals, and they develop a linear and fixed hierarchy in small groups. We found that when chickens were housed in small groups, the top-ranking ...
The Effect of Zinc, Shell, and Fishbone Supplementations on Comb Width and Length of Bangkok Rooster
The Bangkok rooster is a prestigious ornamental bird in Indonesia. Zinc and shell have an aromatase blocker effect that results testosterone elevations. Additionally, fishbone contains rich protein for optimum biological functions. Serum regulates comb size the chicken. This study aimed to investigate of natural blockers roosters. experiment divided thirteen roosters into control treatment grou...
To study expression and function of the vimentin gene, transgenic mice were generated by microinjecting the entire chicken gene plus 2.4 kilobases of 5' and 2.6 kilobases of 3' flanking sequences. All the transgenic mice obtained had incorporated multiple copies of the gene. RNA analyses demonstrated that the chicken vimentin gene was efficiently expressed in an appropriate tissue-specific patt...
Chicken egg lysozyme (cLY) is an enzyme with 129 amino acid (AA) residue enzyme. This enzyme is present not only in chicken egg white but also in mucosal secretions such as saliva and tears. The antibacterial properties of egg white can be attributed to the presence of lysozyme, which is used as an anti-cancer drug and for the treatment of human immunodeficiency virus (HIV) infection. In this s...
Sperm-mediated gene transfer can be a very efficient method to produce transgenic pigs, however, the results from different laboratories had not been widely repeated. Genomic integration of transgene by injection of pseudotyped lentivirus to the perivitelline space has been proved to be a reliable route to generate transgenic animals. To test whether transgene in the lentivirus can be delivered...
The objective of this study was to evaluate the spermatozoa quality of the F4 F5 generation of transgenic rabbit males carrying the mWAP-hFVIII gene in comparison to non-transgenic individuals and previous transgenic generations. Semen samples from 4 transgenic rabbits and 10 randomly selected non-transgenic males of the same breed and age were collected once a week (5 ejaculates per male were ...
A technique for fertilizing zebrafish eggs by injection of sperm nuclei is described. Eggs that cleave normally can develop into swimming larvae and give rise to fertile adults. If sperm nuclei are preincubated for 20 min with DNA encoding the green fluorescent protein, transgene expression can be detected in all cells of the embryo. The use of condensed sperm nuclei allows injection with a sma...
Artificial insemination is a reproductive technology that uses the best male breeders. Successful artificial insemination is affected by several factors, one of the most important and most one is the availability of fertile sperm after the freezing-thawing process. The purpose of this study was to investigate the effect of different concentrations of naringenin after the freezing process. Sp...
