A transgenic line of Yorkshire (YK) pigs named the Cassie (CA) line was produced with a low copy number phytase transgene inserted in the genome. The transgenic line efficiently digests P, Ca, and other major minerals of plant dietary origin. The objectives of this study were to 1) compare carcass and tissue nutrient composition and meat quality traits for third generation hemizygous CA line ma...

The aim of this experiment was to assess the effects of using saturated fatty acid (SFA) and some unsaturated fatty acid (UFA) sources in finishing period on performance, fat deposition and blood metabolites of broiler chickens. One hundred and forty four 28-d old male broiler chickens were randomly assigned to 4 treatments and 6 replicates in a completely randomized design. Four isocaloric/iso...

Four experiments were conducted to determine the effects of dietary supplementation of corn distillers dried grain with solubles (DDGS) diets with mannanase on performance, apparent total tract digestibility (ATTD) of energy and nutrients, blood metabolites, and carcass characteristics of grower-finisher pigs. In Exp. 1, 96 grower pigs (initial BW, 57.6 kg), 6 pigs per pen and 4 pens per treatm...

The current study was conducted to determine the possibility of replacing soybean meal (SBM) in finisher pig diet completely with hydrolyzed feather meal (FM) with blood by supplementing with appropriate amino acids (AA) based on standardized ileal digestible (SID) AA in FM. Corn– SBM, positive control (POS) diets were formulated to contain 6.6 and 5.2 g true ileal digestible (TID) Lys/kg to sa...

Few issues in swine production are as complex as floor space allowances. One method for pork producers to calculate floor space allowance (A) is to convert BW into a 2-dimensional concept yielding an expression of A = k * BW(0.667). Data on ADG, ADFI, and G:F were obtained from published peer-reviewed studies. Five data sets were created: A = grower-finisher pigs, fully slatted floors, and cons...

Sixteen castrated male pigs (averaging 21.2 +/- 4.9 kg) were used in two trials to investigate the effect of dietary amino acid content during the grower phase on growth performance and N balance. In each trial, pigs were assigned randomly to corn-soybean meal grower diets formulated to contain 5.0 or 11.0 g lysine/kg (as-fed basis). Common Finisher 1 and 2 diets were offered when pigs reached ...

New procedures have been developed for the continuous measurement of energy expenditure in finisher pigs. Energy expenditure is measured from oxygen consumption calculated as the product of cardiac output and the difference in blood oxygen content between arterial and mixed venous blood (Fick principle). Key features of this approach have been the use of new technology to measure cardiac output...

Two experiments were conducted to study the effect of phytase supplementation to lowphosphorus starter and finisher broiler diets on mineral utilization and growth performance. All diets in this study were isonitrogenous, isocaloric and corn-soybean diets. In Experiment 1, four replicate groups of 15 commercial broiler chicks, one-day old, were randomly assigned to each of two dietary treatment...

Aims: To evaluate the volumetric amount of endodontic obturating materials remains after retreatment with and without complementary retreatment(XP-Endo Finisher) utilizing two rotary systems (R-Endo EdgefileXR).Materials Methods: Twenty human mandibular premolars single straight root canals were prepared using a 2Shape system file size 25/0.04. Gutta-percha T-Seal (Epoxy resin sealer) used to o...

A completely randomised design experiment was conducted to determine if grouphoused grower-finisher pigs (43.9 to 95 kg) show differences in performance and nitrogen utilisation when provided with a single high lysine diet (11 g/kg) or with a mean lysine concentration of 9.5 g/kg, either as a single diet or as a series of two or four diets. Four hundred and forty pigs were assigned to four diet...
