Nonessential amino acids in tropical ruminant feed: Investigating grass and legume forages of Indonesia.

Objective: This study aimed to examine the concentration of nonessential amino acids (NEAAs) in ruminant feed in tropical areas, with a focus on forage grasses and legumes in Indonesia.

Materials And Methods: A total of 11 grasses ( and ) and six legumes ( and ) were analyzed for NEAA content using high-performance liquid chromatography (HPLC).

Results: Based on the results of this research, it was found that almost all NEAA content in forage was less than 3% (Serine (Ser), Alanine (Ala), Glycine (Gly), Tyrosine (Tyr), Proline (Pro), Cysteine (Cys), and Asparagine (Asn), except for glutamic (Glu) acid and arginine (Arg) in some legumes.

Effect of supplementing L-cysteine and its group analogs on frozen semen quality of bulls: A meta-analysis.

Background And Aim: The quality of frozen bull sperm after thawing is influenced by the primary diluent and antioxidant. This meta-analysis was conducted to determine the effect of supplementing L-cysteine and its group analogs on the quality of frozen bull sperm.

Materials And Methods: A total of 22 articles obtained from Google Scholar and Scopus were integrated into metadata.

Effect of vitamin E supplementation on chicken sperm quality: A meta-analysis.

Background And Aim: Among several factors, the sperm quality of poultry is affected by the rooster's body size and the availability of antioxidants like vitamin E. This study aimed to determine the effect of dietary vitamin E supplementation on rooster sperm quality through a meta-analysis.

Materials And Methods: After verification and evaluation, a total of 19 articles were included in this study.
