Tb78: Food Habits And Body Measurements Of Mourning Doves In Southwestern Maine, Sanford D. Schemnitz Jan 1975

Tb78: Food Habits And Body Measurements Of Mourning Doves In Southwestern Maine, Sanford D. Schemnitz

Technical Bulletins

This study presents the first published information on the food in the crops of Maine mourning doves collected at the Western Maine Forest Nursery at Fryeburg. The main food was conifer seed (54. 6 percent volume). Red and white pine totaled 37. 6 percent of foods consumed. Corn and goosefoot comprised an additional 30.9 percent by volume in the diet. The heavy use of conifer seed by doves in a nursery suggests the need to treat the seed with a repellent. Maine doves were longer in total length than doves from New York and several southern states. The sex ratio …

B639: Alternative Systems For Feeding Maine Dairy Cows, Homer Metzger, Dean F. Tuthill Mar 1966

B639: Alternative Systems For Feeding Maine Dairy Cows, Homer Metzger, Dean F. Tuthill

Bulletins

This study was undertaken as part of a northeast regional effort to ascertain the methods used in feeding forages and concentrates to daily animals and to determine the relative amount of labor used under various systems. Special emphasis was given to methods of handling silages on Maine farms. Information obtained from one-day-a-month timings of feeding chores by 39 dairymen over a period of 13 months permitted comparisons of labor used for various systems of feeding dairy animals.

Tb9: Newcastle Disease Virus Activity And Volume Of Amniotic Allantoic Fluid In Chicken Embryos From Flocks With Different Vaccination Histories, Harold L. Chute, D. C. O'Meara, D. B. Reardon, H. T. Wheelwright

Technical Bulletins

Breeding hens of similar age, 9 to 11 months old, were selected from four flocks, each with a different vaccination history. One flock received no vaccinations, the second received spray and wing web Newcastle disease (ND) vaccine, the third was given three ND dust vaccinations, and the fourth received two dead ND viral vaccinations.

The time spent in getting broilers from the farm to the processing plant is a brief interval, yet it is during this period that most bruising occurs. Bruising lowers the quality of birds. This study from 1960 looks at the cause and amount of quality losses in broilers when they are moved from the farm to the plant; devises methods of reducing quality losses and improving labor efficiency, and evaluates the economic significance of these methods.

B571: Contract Broiler Growing In Maine, Richard F. Saunders May 1958

B571: Contract Broiler Growing In Maine, Richard F. Saunders

Bulletins

The Maine broiler industry had its beginning in the late 1920s and early 1930s with the greatest development occurring after World War II. Live poultry buyers, who later became processors, were the originators of the industry and have played the leading role in its development. Processing and broiler production along with hatching egg production and hatchery operations are vertically integrated to a relatively high degree in Maine. Broiler production in Maine has continued to increase at a more rapid rate than broiler production in the entire United States. By 1957 broiler production in Maine had reached 50 million birds which …
