Improved Iron Status In Weanling Pigs Leads To Improved Growth Performance In The Subsequent Nursery Period, Tyler Chevalier
Improved Iron Status In Weanling Pigs Leads To Improved Growth Performance In The Subsequent Nursery Period, Tyler Chevalier
Theses and Dissertations--Animal and Food Sciences
The objectives of this thesis were: 1) to assess the iron status of piglets, 2) to thoroughly evaluate the blood profile, growth performance, and tissue mineral concentration of young pigs during the pre and postweaning periods after receiving various dosages of iron (0, 50, 100, 200, and 300 mg iron) at birth, 3) as well as evaluate the effects of an additional iron injection before weaning on hematological measures, growth performance, and tissue mineral concentration postweaning. In the initial experiment, there was a 60% incidence of iron deficiency at weaning after administration of a 150 mg iron injection at birth. …

Developmental Changes In The Pig From Birth To 42 Days Post-Weaning (1.5 – 25 Kilograms Bodyweight), Sarah K. Elefson

This study evaluated the changes in body composition, glycogen tissue reserves, visceral organ growth, and small intestine morphology in the young pig. A total of 96 crossbred pigs were euthanized at birth (pre-suckle), days 1, 2, 3, 5, 7, 14 postpartum, weaning at day 21, and days 1, 2, 3, 5, 7, 14, 28, and 42 post-weaning. Body composition of the pig had increasing dry matter and fat, decreasing ash, calcium and phosphorus, and relatively static protein percentage over the course of the study. Liver and muscle glycogen was greatest at birth. Following birth and weaning there was a distinct …
