  • Method for using a ruminant repellent comprising aliphatic aldehydes
    Patent number: 4065577
    Abstract: A method for discouraging ruminants from browsing edible material normally eaten by such ruminants comprises contacting the material and/or the region adjacent such material with a repellent composition. The repellent composition contains as the active repellent ingredient an aliphatic aldehyde, preferably having from six to twelve carbon atoms. The repellent composition can also be applied to the material as a repellent-producing composition that is an oxidation precursor of the aliphatic aldehyde.
    Type: Grant
    Filed: June 30, 1976
    Date of Patent: December 27, 1977

  • Ruminant repellent from fresh lipoidal material
    Patent number: 3980773
    Abstract: A ruminant repellent is a composition which, when applied directly to or applied to the area surrounding edible material such as living plants, discourages ruminant animals from browsing such edible material. The ruminant repellent of the invention comprises a composition of matter containing a phospholipid as an active repellent ingredient. Phospholipids extracted from animal or plant lipoidal material contain the active repellent material which effectively discourages browsing by ruminants. Within the phospholipid fraction, lecithin and cephalin are active repellent components. Examples of phospholipid source materials which can be applied to edible material to effectively repel ruminants are unputrefied whole eggs, dried, powdered whole eggs, unputrefied egg yolk, and lipoidal material derived from ground shellfish and fish (such as shrimp or anchovy). If desired, preservatives can be added to the repellent composition to prevent or delay putrefaction in order to form a long lasting product.
