Effects of nonconventional feed additives on egg efficiency of laying hens

The study contains the materials of scientifi and economic experiment on application of nonconventional feed additives: feed additive from waste of processing of shrimps and the fl from Eastern galega (Galega orientalis) in feeding of laying hens. Two scientifi and economic experiments on inclusion in a diet of laying hens of these feed additive were made. The experiments were made on the hens of cross-country of Hayssex White cross white in the conditions of Primorsk Region. The purpose of the researches was to study the possibility of inclusion in the diets of laying hens of the fodder fl from shrimps and the vegetable additive made of Eastern galega. The tasks were to defi optimum doses of feeding of these additives in diets of laying hens, to study egg production of layers at the inclusion of additives from waste of shrimp trade and Eastern galega, to compare the commodity qualities of eggs received from experimental laying hens. Before the experiment statement all the poultry was divided into eight groups: two control groups and six experimental groups. During scientifi and economic tests experimental groups' poultry was in identical conditions. The conditions of keeping of laying hens of cross-country of Hayssex White cross were similar. The distinctions were only in feeding. The control group received only the diet accepted on the farm. The birds of experimental group besides compound feed received still feed additives by import substitution. It was by practical consideration proved that data given additives have positive impact on egg production of laying hens of cross-country Hayseks White. So, at the inclusion of the fodder fl from shrimps in a diet of laying hens the following results were received: gross production of eggs increased by 19 %. The inclusion into the diet of layers of the additive of plant origin raised egg production of laying hens of experimental groups for 10.5-14.9 %.
