Cover Story: High rates of embryonic deaths are a major factor limiting reproductive efficiency in cattle, particularly in tropical and subtropical regions of the world. However, effective nutritional methods to prevent or alleviate this problem are not available. Extracellular citrulline does not undergo catabolism by ruminal microbes in ruminants and is effectively converted into arginine in post-rumen extrahepatic tissues, including the kidneys and uterus. Arginine is a conditionally essential amino acid for gestating mammals and their fetuses, playing an important role in embryonic and fetal survival, growth, and development through the production of bioactive molecules (e.g., nitric oxide and polyamines). Dietary supplementation with citrulline is a simple, novel, and cost-effective method to increase the reproductive efficiency of beef cows. View this paper
