Can Mechanical Methods of Feeding Poultry Replace Hand Methods?

INTRODUCTIONPOULTRYMEN are constantly searching for ways to stimulate and maintain maximum feed consumption as a means to attaining maximum egg production and livability in adult flocks. Pellets, wet mash, and condensed buttermilk are three supplements used by poultrymen to stimulate feed consumption. Stirring the dry mash in hoppers several times a day has been another method used to increase mash consumption. Since these practices add up to higher labor and feed costs, a number of pertinent questions have been raised. First, does feeding of pellets and wet mash increase total feed consumption as compared to feeding dry mash at frequent intervals with an automatic feeder; second, will automatic feeding of mash result in as satisfactory egg production and livability as obtained by an accepted method of hand feeding?DESIGN OF EXPERIMENTAL FEEDERAn automatic mash feeder was designed, constructed and placed in operation in February, 1947 (Figure 1). The .

Alimentação dos marrecos: III sôro de leite (Líquido)

The author studied in this paper the influence of liquid whey in feeding Pekin ducklings. Wet mash, either by liquid whey or water, was given to the ducklings during the whole day. Green feed was added to the ration just once a day. The statistical analysis did not show significant differences between the use of water and liquid whey but the results obtained with wet mash proved to be statistically better than the results obtained with dry mash.

The author reports in this paper the results obtained in one experiment with wet an dry mash on the growing of chickens. The experiment started with two groups of 50 Sussex bred each, one receiving dry and other wet mash. The observations were continued in another four groups of 25 chickens each, two of Rhod Island Red bred and two of Sussex bred, both receiving dry and wet mash. The chickens were weight every 10 days and the differences obtained proved to be not significant statistically. Both dry and wet mash were equally good but wet mash is much more dificult to give to the chickkens than the dry one.

A complex pig-feeding experiment

Summary1. The conditions which must be fulfilled in the design of an animal husbandry experiment if the results are to be statistically valid are summarised, together with possible methods of improving the efficiency by suitable design.2. The results of a pig-feeding experiment conducted at Rothamsted are discussed. The experiment showed that green food was essential to young pigs under the conditions of the experiment, that pigs fed on a wet mash grew at a faster rate than pigs fed on dry meal, the difference being due to the greater quantity of food consumed by the former, and that the effects of numbers in a pen (giving equal floor space per pig) were negligible in spite of the greater possibilities of exercise in the larger pens.

Hatching Quality of Eggs With Relation to Management

From the nature of the case, experiments dealing with the management of breeders in relation to the hatching quality of their eegs require large resources and so data accumulate slowly. For this reason the following tests are published.Great difficulty has been experienced for several years past in obtaining chicks from the fertitle eggs of our breeders of two years of age or more, though no difficulty is had with birds a year old. Suggestions from some of the recent work with vitamins brough about changes in the general method of handling the breeders, with which the following tests have been associated.The breeders were housed in a two story building facing southwest. From early December, scratch feed only was given, till mid January, 1925, when the dry mash was returned and in addition a wet mash made from the dry and carrying two ounces of cod liver oil per .
