Effect of heat treatment of fish meals,fines and the addition of lysine as related to gizzard erosion in chickens

The effect was studied of certain properties of fish meal on their tendency to predispose chickens to develop gizzard lesions when used in starter diets. These properties relate to the degree of heat treatment to which the meals had been subjected, the fineness of the meal, and the fish species involved. The effect on gizzard erosion of addition of dietary lysine was also considered. The results suggest that the use of meals heated to 130°C or higher, but not of meals stored at lower temperatures, is more likely to result in the development of gizzard lesions, while the fineness of the fish meal had no effect on this phenomenon. In some instances added dietary lysine reduced gizzard erosion incidence. No relationship was found between chicken liveweight gain during the experimental period and gizzard lesion scores. A 7-day biological test was used in these studies.

Phospholipids of marine origin. The lantern fish (Lampanyctodes hectoris)

Lantern fish of the species Lampanyctodes hectoris were shown to contain phospholipids (10 g kg^?1) and non-phosphorylated lipids (140 g kg^?1). The phospholipid fraction consisted of phosphatidyl choline (47% of total phospholipids), phosphatidyl ethanolamine (42%), phosphatidyl serine (3%), phosphatidyl inositol (1%), sphingomyelin (4%), lyso-phosphatidyl choline (1%) and cardiolipins (2%). Lantern fish (L hectoris) meals normally contain unacceptably high lipid contents (150 g kg^?1 and over); this characteristic was found not to be due to a high phospholipid level in the lantern fish. The major fatty acid of the phospholipids was C22:6n-3 (25% total fatty acids) followed by C16:0 (18%), C18:ln-9 (16%) and C20:5n-3 (8%). This distribution was different from that of the non-phosphorylated lipids where the major fatty acid was C16:0 (21%) followed by C18:ln-9 (19%), C20:5n-3 (11%), C20:l (7%) and C22:6n-3 (7%). The lantern fish press oil and residual meal lipids had fatty acid distributions similar to those of the non-phosphorylated lipids.

Projecting Faith: French and Belgian Catholics and the Magic Lantern Before the First World War

Abstract

Around 1900, the Catholic Church in Belgium and France started to systematically use the magic lantern for religious education, but also as a propaganda tool in their fight against their laic opponents in both countries. In the course of the nineteenth century, the magic lantern had become a major visual mass medium in Europe and the United States. The light beam of the lantern was seen as a powerful means to sustain faith and disseminate the views of the Church. While numerous members of the Catholic clergy embraced the projections lumineuses as a continuation of the long-standing tradition to teach the gospel through images, from glass windows to paintings, they had to face opposition by those who thought the magic lantern unfit to be used to lecture on religious matters. Despite such resistance, the projected image became an important medium used throughout the first decades of the twentieth century by the Catholic Church.
