A total of 1,480 pigs were used in 3 experiments to determine the effects of corn distillers dried grains with solubles (DDGS) varying in oil content on growth performance, carcass traits, and nutrient digestibility in finishing pigs. In Exp. 1, 1,198 pigs (PIC Line 337 × 1050; initially 46.1 kg) were allotted to a corn-soybean meal-based diet or diets with 20 or 40% of a 5.4% oil DDGS (29.5% C...

The key chemical analysis used to estimate the energy value of alfalfa hay for trading purposes, ADF (acid detergent fiber), has been supplanted by NDF (neutral detergent fiber) as the key chemical analysis used by nutritionists to evaluate the fibrosity and energy value of alfalfa hay for nutritional purposes. It is important that the alfalfa hay trading industry abandon ADF, as it will genera...

A study involving a 2 x 2 x 2 factorial arrangement of treatments was conducted to evaluate effects of hybrid (Pioneer 3335 and 3489), maturity (half milkline and blacklayer), and mechanical processing (field chopper with and without on-board rollers engaged) on intake and digestibility of corn silage. Forty Angus steers (322 +/- 5.2 kg BW) were assigned to the eight silage treatments (five ste...

The comparison of the predictions of the digestible energy (DE) content of commercial compound pig feeds from the organic matter in vitro digestibility (OMD) and five recent and accurate multiple regression equations based on chemical components was examined. The OMD was determined by submitting each sample (17 compound feeds for lactating or pregnant sows and 23 for piglets and growing±fatteni...

A study was conducted to evaluate the nutrient content and variability of distiller’s dried grains with solubles (DDGS) originating from new (less than 5 yr. old) ethanol plants in MN and SD. Ten plants (8-MN, 2-SD) participated in the study, submitting a total of 88 samples. Samples of DDGS were collected every two months during 1997 (n=38) and 1998 (n=50) and were sent to the University of Mi...

A study was conducted to characterize the carbohydrate and protein fractions of barley-based distillers grains (BDG) derived from a mix of 70% barley, 20% wheat and 10% rye/triticale. Amino acid composition, ruminal escape protein and amino acid values, and ruminal nutrient degradability of BDG were determined relative to wheat-based distillers' grains (WDG) derived from 100% wheat. On a dry ma...

Twenty-one multiparous sows were used in a Latin square design, from days 7 to 90 of gestation, to test the effect of fibre and food levels on feeding motivation and feeding-related stereotypies. Treatments were: VHF (very high-fibre, 29% ADF, 50% NDF, 4.5kg/day); HF (high-fibre, 23% ADF, 43% NDF, 3.5kg/day); C (control, 8% ADF, 20% NDF, 2.5kg/day); and control fed ad libitum (CAL). All diets e...

The objective of this study was to determine the chemical composition and in situ degradability dry matter (DM), crude protein (CP), acid detergent fiber (ADF), neutral (NDF) stockpiled perennial forage (SPF) or sun-cured hay (HAY) when collected at start end (October vs. December) fall grazing. Selected 6, 4-ha paddocks consisting meadow bromegrass alfalfa, were randomly assigned 1 2 replicate...

The aim of this experiment was to investigate the beneficial effect monensin, tannic acid and cinnamon essential oil addition on sesame meal degradability by three-step in vitro method. experimental additives rumen, after rumen whole gastrointestinal tract significant (P<0.05). ruminal intestinal digestibility crude protein with range 76 84% 49 60%, respectively. increased (about 10%). Addit...

Five trials were conducted to evaluate the energy value of corn wet milling by-products in finishing diets. In trials 1 (45 finishing lambs, 34 kg) and 2 (70 digestion wethers, 32 kg), Rambouillet X Suffolk lambs fed corn gained faster (P less than .10), more efficiently (P less than .10) and had higher (P less than .01) digestibilities of neutral and acid detergent fiber (NDF, ADF) and starch ...
