Furthee Biochemical Studies Op Pregnancy Toxæemia in Sheep

Changes in the Liver Fat of the Pregnant Sheep at Different Levels of Nutrition and during Starvation

“…The importance of a study of the ovine fatty liver arises from the frequent reports of this condition in cases of pregnancy toxaemia occurring in the field or induced experimentally (Roderick & Harshfield, 1932 ;Frazer, Godden, Snook & Thomson, 1938-9, 1939Groenewald, Graf, Bekker, Malan & Clark, 1941 ; Underwood, curnow & Shier, 1943). According to Best & Ridout (1933, 1936, Best (1934), Best & Channon (1935), Best & Huntsman (1934-5), Best, Mawson, NIcHenry & Ridout (1936) and Channon & Wilkinson (1934), excessive fat accumulates in the liver of experimental animals, principally rats, under a variety of circumstances, e.g.…”

Effect of gestation and lactation nutrition of sows on the livability and growth of their pigs

“…Yestal (161), Weaver and Bogart (169) and Winters et al (175) found that the pigs' weight at birth had a great effect upon survival, daily gains and weaning weight. Winters and associates (l75) found that an increase of one pound in average birth weight increased weaning weight 15,9 pounds.…”

“…These differences were reflected quite unmistakably in the results obtained. Weaver and Bogarb at the Missouri Station (169) have demon strated that •breeding affects the level of sow productivity vAich includes the number of pigs farrowed and weaned per litter and milk producing capacity as well as litter weight at Tjeaning. ^hese authors confirm a long known fact that gilts selected from efficient producing sows tend to inherit productive a'bility.…”

“…Yi[eaver and Bogart (169), Meyer (il8) Under field condition, Srider (96) believes jnany deficiencies are multiple in nature and some of them may be due to borderline nutrition.…”
