Mycobacterium infection in a gray-cheeked parakeet.

A gray-cheeked parakeet, approximately 3 years of age, was submitted for necropsy. Clinical signs included diarrhea, decreased feed consumption, fluffing of feathers, shivering, weight loss, and limping. Necropsy revealed enlargement and pale discoloration of the spleen and intestines.

Reproductive performance of medium white breeder toms fed diets with varying metabolizable energy levels and 7% crude protein.

An experiment was conducted to study the effects of feeding diets composed of triticale (var: Flora) with varying ME levels and 7% CP on fertilizing capacity and semen quality of Medium White breeder toms. Thirty-nine breeder toms were fed ad libitum from 30 to 54 wk of age one of four dietary treatments: 14% CP with 2,892 kcal ME/kg; 7% CP with 2,919 kcal ME/kg; 7% CP with 2,719 kcal ME/kg; and 7% CP with 2,539 kcal ME/kg. Semen volume (SV), packed spermatozoa volume (PSCV), BW, testicular weight (TW), and fertilizing capacity of semen were measured.
