The research was aimed to study the potential of probiotic lactic acid bacteria as suitable alternatives to antibiotics in broilers. This was design to find a possible replacement to antibiotics in broiler production. The study was carried out at the Department of microbiology, faculty of sciences Kaduna State University, Kaduna between January to May 2018. A total of ten raw milk samples were screened for the isolation of Lactic Acid Bacteria and 20 day-old broiler chicks (initial body weight 41 ± 0.5 g) were administered probiotics containing Lactobacillus fermentum, Lactobacillus plantenrun and Weissalla ciberia in water at 108 cells/milliliters/isolates/birds/day at day 6, 7, 8, 21, 22, and 23 of ages. Body Weight (BW), Weight Gain (WG) and Feed Intake (FI) were measured weekly just as feed conversion ratio was calculated and mortality recorded throughout the duration of the experiment. Blood glucose concentration, total protein, lipid profiles and Total immunoglobulins (IgY) were determined from blood sample at the ages of 14 and 42 days. Carcass quality and proximate analysis were evaluated from the meat of the broiler at the age of 42 days.

Europe has a distinguished history of environmental research and hosts many of the world s leading researchers in the environmental field. Environmental concerns have been on the policy agenda since the European Comunities were created in 1957. The International Geophysical Year (IGY) was launched in the same year as a first attempt to coordinate global measurements of the Earth, the oceans, the atmosphere and the sun. It also pointed out for the first time that carbon dioxide was building up in the atmosphere. The decades since then have witnessed increasing public concern about our environment and the damage being done to it, alongside greater research efforts to increase knowledge and find solutions.

Avian Immunogloblins

Antibodies are the functional unit of humoral immunity. They are secreted by plasma cells, a type of B lymphocyte. When on the surface of a B cell, these molecules are immunoglobulins, following secretion they are termed as antibodies. Antibodies are found in bodily fluids and tissue spaces and are most effective in eliminating extracellular pathogens. As compared to mammalian antibodies, IgY offers various advantages for the targeted extraction of antibodies and their application in bioanalysis. Since the antibodies are extracted from the yolks of laid eggs, the method of antibody production is non-invasive. Thus, no blood must be taken from the animals for the extraction of blood serum. Because of its economic importance most research on immunity implied in the reactivity of the body were performed on domestic birds. Direct consequence of this research is the understanding of fundamental and applied concepts of immunity in birds. Comparing to the mammalian, avian immune system appears insignificant. However, it currently provides important information regarding the fundamental immunological mechanisms. It also provided a significant number of firsts, especially in vaccinology.

The 'Year' That Changed How We View the North This book is about a new theoretical approach that transformed the field of Arctic social studies and about a program called International Polar Year 2007-2008 (IPY) that altered the position of social research within the broader polar science. The concept for IPY was developed in 2003-2005, its vision was for researchers from many nations to work together to gain cro- disciplinary insight into planetary processes, to explore and increase our understanding of the polar regions, the Arctic and Antarctica, and of their roles in the global system. IPY 2007-2008, the fourth program of its kind, followed in the footsteps of its predecessors, the first IPY in 1882-1883, the second IPY in 1932-1933, and the third IPY (later renamed to 'International Geophysical Year' or IGY) in 1957-1958. All earlier IPY/IGY have been primarily geophysical initiatives, with their focus on meteorology, atmospheric and geomagnetic observations, and with additional emphasis on glaciology and sea ice circulation. As such, they excluded socio-economic disciplines and polar indigenous people, often deliberately, except for limited ethnographic and natural history collection work conducted by some expeditions of the first IPY. That once dominant vision biased heavily towards geophysics, oceanography, and ice-sheets, left little if any place for people, that is, the social sciences and the humanities, in what has been commonly viewed as the 'hard-core' polar research.

In 'Big Ecology,' David C. Coleman documents his historically fruitful ecological collaborations in the early years of studying large ecosystems in the United States. As Coleman explains, the concept of the ecosystem--a local biological community and its interactions with its environment--has given rise to many institutions and research programs, like the National Science Foundation's program for Long Term Ecological Research. Coleman's insider account of this important and fascinating trend toward big science takes us from the paradigm of collaborative interdisciplinary research, starting with the International Geophysical Year (IGY) of 1957, through the International Biological Program (IBP) of the late 1960s and early 1970s, to the Long-Term Ecological Research (LTER) programs of the 1980s.

Althoff, W: Artic Mission

To help salve the sting of orbiting Sputniks, the United States needed a dramatic demonstration of technological prowess; early in 1958, the White House ordered a top secret under-ice transit of the Arctic Ocean--Pacific to Atlantic--via the North Pole. And that spring, the Office of Naval Research initiated a unique project: to assess whether non-rigid airships (blimps) could support field parties deployed in the Arctic. This book recounts two successful missions. In August, the nuclear submarine Nautilus (SSN 571) reached 90 North and, continuing under ice, logged the first deep-ocean transit of the basin. En route to rendezvous with an IGY drifting station on T-3, an ice island, U.S. Navy airship BUNO 126719 became the sole military airship to cross the Arctic Circle. This work is based on first-hand accounts, including journal excerpts from Dr. Waldo Lyon a force behind U.S. under-ice submarine development
