Disappearance And Appearance Of An Indigestible Marker In Feces From Growing Pigs As Affected By Previous- And Current-Diet Composition, Brandy M. Jacobs, John F. Patience, Merlin D. Lindemann, Kenneth J. Stalder, Brian J. Kerr

Animal and Food Sciences Faculty Publications

Background: Indigestible markers are commonly utilized in digestion studies, but the complete disappearance or maximum appearance of a marker in feces can be affected by diet composition, feed intake, or an animal’s BW. The objectives of this study were to determine the impact of previous (Phase 1, P1) and current- (Phase 2, P2) diet composition on marker disappearance (Cr) and appearance (Ti) in pigs fed 3 diets differing in NDF content.

Results: When pigs were maintained on the 25.1, 72.5, and 125.0 g/kg NDF diets, it took 5.1, 4.1, and 2.5 d, respectively, for Cr levels to decrease below the …

The Effect Of Feed Form On Diet Digestibility And Cecal Parameters In Rabbits, Isabella Corsato Alvarenga, Charles Gregory Aldrich, Micah Kohles

School of Veterinary and Biomedical Sciences: Faculty Publications

Fifteen New Zealand rabbits were randomly assigned to one of 3 dietary treatment groups of 5 animals each and fed pelleted, extruded, or muesli diets in a completely randomized design experiment. Rabbits were placed in individual cages with ad libitum access to water and food for 45 days acclimation followed by 30 days experimental period. Feed intake of rabbits fed pelleted and extruded diets was greater (p < 0.05) than rabbits fed the muesli diet (125.6 and 130.4 vs. 91.9 g/d), but weight change and feed efficiency were not affected by treatment. Diet digestibility among the treatments was inconsistent when comparing results obtained from total fecal collection and AIA (please define) as an internal marker. Rabbits fed extruded and pelleted diets had lower (p < 0.05) cecal pH (6.42 and 6.38 vs. 7.02, respectively), and higher (p < 0.05) production of SCFA (18.5 and 19.0 vs. 11.7 mM, respectively) than those fed muesli. The fermentation products from rabbits fed pelleted and extruded diets had a greater proportion of butyrate and less propionate than rabbits fed muesli. The results of this study indicate that the basal dietary composition had a greater impact on diet utilization and cecal fermentation than food form.

Barley As An Alternative To Rice In Dog Food, Fatma İnal, Mustafa Selçuk Alataş, Oğuzhan Kahraman, Şeref İnal, Mustafa Uludağ, Emel Gürbüz, Esad Sami̇ Polat

Turkish Journal of Veterinary & Animal Sciences

In this study, 30 mixed-breed, neutered, young adult male dogs at 15-30 kg live weights were used. The foods were produced at a special facility. Dog food produced using 25% barley had a gelatinized starch content significantly greater than that of food produced using 25% rice: 18.36% vs. 17.45%, respectively. No considerable difference was observed in the dogs' preference between the two foods (50.95% vs. 49.05%). Dry matter digestibility of rice and barley food was 86.10% and 83.85% and crude protein digestibility was 80.44% and 79.24%, respectively. Based on the consumption of rice or barley, stool consistency did not change.

Effect Of Phytase On True Total Tract Digestibility Of Phosphorus In Full-Fat Rice Bran Determined In Pigs By Regression Method, Walter Lucca, Marcos Ceron, Matheus Lucca, Lucas Casagrande, Leonardo Rocha, Irineo Zanella, Vladimir Oliveira

Turkish Journal of Veterinary & Animal Sciences

The goal of this study was to determine the effect of phytase on true total tract digestibility of phosphorus (TTDP) and endogenous losses of phosphorus (ELP) of full-fat rice bran (FFRB) by simple linear regression. Twelve castrated pigs in the growing phase with an average live weight of 57.00 ± 2.50 kg were used. The experiment lasted 36 days, divided into three periods of 12 days each. The experimental design consisted of randomized blocks in a 2 × 3 factorial scheme, with two levels of fungal phytase (0 and 750 FTU $\mathbb{kg}^-1$ ) and three levels of phosphorus (P) coming …

Response Of Dairy Cows To Dietary Starch Concentrations: Performance, Nutrient Digestion, And Gas Emissions, Juan Isidro Sanchez-Duarte

Electronic Theses and Dissertations

Three studies and a meta-analysis were conducted to determine the performance, nutrient digestion, and gas emissions of dairy cows fed diets with different starch concentrations (19 to 27% of DM). Study 1 evaluated the effects of reducing corn grain starch with non-forage fiber sources (NFFS, soybean hulls and beet pulp) in diets of soybean meal (SBM) or canola meal (CM). In study 1, reducing starch from 27 to 20% with soybean hulls and beet pulp had a negative effect on dry matter intake (DMI), milk yield and energy-corrected milk (ECM), regardless of the crude protein (CP) source. Those effects were …
