Abstract

The purpose of this study was to determine the effect of litter system and interaction of both different level of cage density grower arab chicken. The material used were 48 arabic chicken at grower period which the age 2 months and the average weight 701.7±94.37 g  and the value SD 13.45%. The method used in this study was experimented with completely randomized design (CRD) factorial patterns. First factor was litter system  dan  second factor was the level of cage density. Data were analyzed by analysis of variance (ANOVA) , if there was different followed by duncan multiple range test. The results showed that litter system of cage was not showed any significant effect (P>0.05) on feed consumption, weight growth and  feed conversion. The level of cage density was gave significant different (P<0.01) on feed consumption, weight growth and feed conversion. Interaction between litter system and different level of cage density were not gave significant effect (P>0.05). The conclusion of this study there was not interaction between factor litter system and the level of cage density.

Abstract

Bees use pollen as a source of protein to support life and to increase the productivity. The size and type of pollen carried by bees are very diverse. Plants in high altitudes may produce pollen of different diameters than those in low altitudes. It is necessary to measure pollen diameter from different plants to know the honeybees’ preferred food source. The purpose of this research was to determine the effect of altitude on pollen diameter from various types of plants carried by bees to increase honey production. This was done by performing field experiments. The design used for this experiment was the completely randomized linear model with three altitude treatments, which were 0-100 m asl (P1), 400-499 m asl (P2) and 800-899 m asl (P3). The results show that altitude has a significant effect (P<0.01) on honeybee Apis cerana pollen diameter. The equatorial and polar pollen diameter was reached by P2 wich was 42.1 ± 4.69 µm and 49.0 ± 4.98 µm, respect highly. Where as the smallest equatorial and polar pollen diameter was reached by P1 wich was 21.1 ± 1.45 µm and 27.0 ± 2.64 µm. To fulfill pollen needs, Apis cerana bees do not necessarily depend on specific pollen diameters. These bees are taking pollens with equatorial diameter of 8.52 μm to 93.68 µm and dan polar diameter polen 8.93 µm to 97.99 µm.
