This document discusses oats, including their characteristics, identification, nutritive profile, production, anti-nutritive factors, and price. Oats are a cereal grain domesticated in Europe with high fiber and low energy content compared to other grains. They provide various vitamins and minerals. Oats are processed through cleaning, dehulling, kilning, sizing, cutting, milling, and flaking. They are harvested using combine harvesters or binders and stored in dry, cool conditions to prevent deterioration. Oats contain some anti-nutritional factors like phytate and trypsin inhibitors that reduce nutrient availability.

Grain quality

Pwani University

1. Grain quality factors like test weight, foreign material, broken kernels, and moisture content can impact the value of grain for both trade and animal feeding. 2. Test weight alone has little effect on animal performance if animals can meet their energy needs, but impacts value when grain is sold by volume. Foreign material depends on what it is but can reduce storage quality. 3. Both physical and chemical analyses are important for evaluating grain quality factors and potential issues like mycotoxins that impact animal health and performance. Maintaining proper storage conditions is key to preserving grain quality.

Oat fodder

Dr. Muhammad Ammun Bashir

Oats are a cereal grain species known as Avena sativa. They originated in Bronze Age Europe and have since been domesticated. Oats are high in fiber but also contain important nutrients. The processing of oats involves cleaning, dehulling, kilning, sizing, cutting, milling and flaking. Harvesting is typically done with a combine harvester or grain binder. Oats must be stored in cool, dry conditions to prevent deterioration from moisture, heat and insects. While nutritious, oats also contain some anti-nutritive factors like phytate, trypsin inhibitors and tannins that can reduce nutrient availability if consumed in large quantities.

SNV-KMDP Forage Interventions in Kenya

ProDairy E.A. Ltd

KMDP has built up rich knowledge and experience as regards good practice forage production and preservation for smallholder, medium and large scale dairy farms (from seed to feed). In addition to that, it has successfully piloted commercialization of quality forages and of forage contracting services. This was achieved through the SPEN model and the concept of “maize train” (i.e. mechanized agricultural contracting services for maize production, harvesting and silage making), and by facilitating introduction of innovative machinery for making baled silages. Through replication and upscaling, this will ensure enhanced access of quality forages for small medium and large-scale dairy farms. In 2018 KMDP-II also started a pilot on introduction of feed rationing software to help optimizing total rations and margin over feeds. KMDP participates in sector platforms that discuss forage availability in Kenya and supported the National Fodder Conference in Nakuru in December 2017 and the Animal Production Society in Nanyuki in March 2018

Feed technology by Abhishek Sharma

College of Veterinary and Animal Science, Bikaner

This presentation show about feed technology how to feed and fodder process their History, Principles, classification and some related definition its also helpful to graduate student and post graduate student FEED TECHNOLOGY Definition The subject of feed technology deals with processing of feeds, fodders and preparation of formula feeds for which the knowledge of nutritional requirements of various livestock and poultry, quality control of feed ingredients, feed plant management and the storage of feed ingredients and feeds are essential. Animal feed technology may also be defined as the application of physical, chemical, biochemical, biological and engineering techniques to increase the nutrient utilization of feeds and fodders in animal system for the development of livestock and poultry and feed industry. Beginning of feed Industry and related Activities in the US:- • In 1875 Mr. john barwell initiated the production of a calf meal at Blatchford of Waukegan, Illinois. • American Feed Manufacturers Association (AFMA) was founded in 1909 in Wisconsin and its name was changed to American Feed Industry Association (AFIA) in 1985. • The Association of American Feed Control Officials (AAFCO) was established in 1909. • Linear programming, a mathematical procedure, was developed by George B. Dantzig in 1947. • W.V. Waugh of USDA was the first to see the potential of this mathematical procedure and developed a least cost dairy feed in 1951. • Food and drug Administration (FDA) was passed in 1906 in USA. *Some of the AAFCO Definitions:- 1. Complete feed: - A nutritionally adequate feed for animals other than humans and is capable of maintaining life and / or promoting production without any additional substance, except water. 2. Concentrate:- A feed used with another to improve the nutritive balance of the total and intended to be further diluted and mixed to produce a supplement or a complete feed. 3. Supplement:- A feed used with another to improve the nutritive balance or performance of the total and intended to be (1) fed undiluted as a supplement to other feeds, (2) offered free- choice with other parts of the ration separately available or (3) further diluted and mixed to produce a complete feed. 4. Premix:- A uniform mixture of one or more micro-ingredients with diluents and carrier. Development of Feed Industry in India:- • Feed industry came into existence in India in 1961 with the establishment of a feed plant in Ludhiana, Punjab. • Compound Livestock Feed Manufacturers Association (CLFMA) was formed on 8 June, 1967. •

Cosa hanno in comune un mattoncino Lego e la backdoor XZ?

Speck&Tech

ABSTRACT: A prima vista, un mattoncino Lego e la backdoor XZ potrebbero avere in comune il fatto di essere entrambi blocchi di costruzione, o dipendenze di progetti creativi e software. La realtà è che un mattoncino Lego e il caso della backdoor XZ hanno molto di più di tutto ciò in comune. Partecipate alla presentazione per immergervi in una storia di interoperabilità, standard e formati aperti, per poi discutere del ruolo importante che i contributori hanno in una comunità open source sostenibile. BIO: Sostenitrice del software libero e dei formati standard e aperti. È stata un membro attivo dei progetti Fedora e openSUSE e ha co-fondato l'Associazione LibreItalia dove è stata coinvolta in diversi eventi, migrazioni e formazione relativi a LibreOffice. In precedenza ha lavorato a migrazioni e corsi di formazione su LibreOffice per diverse amministrazioni pubbliche e privati. Da gennaio 2020 lavora in SUSE come Software Release Engineer per Uyuni e SUSE Manager e quando non segue la sua passione per i computer e per Geeko coltiva la sua curiosità per l'astronomia (da cui deriva il suo nickname deneb_alpha).

Removing Uninteresting Bytes in Software Fuzzing

Aftab Hussain

Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process. In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds. - These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.
