Effects of nonantibiotic feed additives on performance, nutrient retention, gut pH, and intestinal morphology of broilers fed different levels of energy.

An experiment was conducted to determine the effects of different feed additives on performance, nutrient retention, gut pH, and intestinal morphology of broilers fed different levels of energy. This study was a 4 × 2 factorial arrangement of 4 feed additive programs (a basal diet without any feed additive as the control, the basal diet with added organic acid, the basal diet with added prebiotic, and the basal diet with added probiotic) with recommended levels (3,150 and 3,200 kcal of ME/kg of diet for the starter and finisher diets, respectively) or low levels (90% of recommended) of energy. A total of 640 one-day-old male and female broiler chicks were randomly assigned to 8 treatments. Each treatment consisted of 4 replicate floor pens of 20 birds each. Starter and finisher diets were fed from 1 to 21 d and 21 to 42 d of age, respectively. Dietary levels of other nutrients, housing, and general management practices were similar for all treatments. Dietary inclusion of additives had no significant effects on broiler performance, intestinal villus height, crypt depth, gut pH, and dietary AME. Birds fed the low-energy diets were heavier but had inferior FCR compared with those fed the recommended-energy diets. Prebiotic and organic acid significantly (P < 0.05) improved protein digestibility. The recommended-energy diets significantly (P < 0.05) increased AME and protein digestibility. No interactions were observed for the measured parameters

Atmos Programmunterstuetzung Endbericht

The study 'Atmos Programme Support' comprises parts of the national Atmos programme for terrestrial observation and for acquisition of environmentally relevant scientific data of the fields of land, water, and air. In particular, the investigation is to support the national organisation DARA in the development of the instrument AMAS (Advanced Millimeterwave Atmospheric Sounder) and in the identification of missions in which AMAS could take part. An adapted configuration was developed for AMAS as part of the payload during Atmos Phase B1. Parallel to Atmos Phase B2, further design investigations of AMAS were made, but no further adaptation of the configuration. As a result, it became necessary in the configuration on the one hand to take account of the latest design developments and on the other hand to adapt the accomodation to a possible carrier platform. Both POEM/Envisat and other (Russian) carriers are possible. Another aspect is the development of AMAS in the framework of a cost-sharing cooperation.

Insbesonder liegt der Schwerpunkt der Studie in der Unterstuetzung des nationalen Auftraggebers DARA bei der Entwicklung des Instrumentes AMAS (Advanced Millimeterwave Atmospheric Sounder) sowie in der Identifizierung von Missionen, an denen AMAS teilnehmen koennte. Fuer AMAS als Teil der Nutzlast wurde waehrend der Atmos Phase B1 eine angepasste Konfiguration entwickelt. Parallel zur Atmos Phase B2 fanden weitere Designuntersuchungen von AMAS satt, aber keine weitere Adaption der Konfiguration. Daraus resultierte die Notwendigkeit, einerseits in der Konfiguration die letzten Designentwicklungen zu beruecksichtigen, andererseits aber auch die Akkommodation auf einer moeglichen Raegerplattform anzupassen. Hierbei kamen sowohl POEM/Envisat als auch andere - russische - Traeger in Frage. Ein zusaetzlicher Gesichtspunkt ist die Entwicklung von AMAS im Rahmen einer kostenteiligen Kooperation.

Teilsysteme ATMOS - Fortfuehrung. Bd. 2. Anlage 7: AMAS/GUS-Kooperation Abschlussbericht

This final report contains the objectives, execution and results of the activities into the project ''ATMOS Subsystem - Continuation''. This project was the immediate continuation of the activities into the study ''ATMOS Subsystems''. The objective of the terms of reference was the concrete treatment of tasks from the instrument program SCIAMACHY (Scanning Imaging Absorption Spectrometer for Atmospheric Chartography) and AMAS (Advanced Millimeterwave Atmospheric Sounder), and mission planning. Mission planning involved investigations of secondary payload launch opportunities of the AMAS instrument on the Russian platforms MIR-2, RESURS-0, METEOR-3M, and RFZ SPEKTR. Within the task ''AMAS-CIS Cooperation'', proposals were indicated for possible CIS cooperations and for further secondary payload launch opportunities on OKEAN-0 and on a multi-purpose space platform. Under the leadership of Jena-Optik, the verification model of a high-resolution optical angle encoder was developed, assembled and verified. This final report comprises five volumes. Volumes 1 and 2 contain the activities into the EGSE, MGSE, EGSE software, calibration device, thermal balance, CIS cooperation and secondary payload launch opportunities. Volumes 3, 4 and 5 comprise the activities into the development and verification of the angle encoder.
