Kansas Agricultural Experiment Station Research Reports
A total of 3,451 mixed parity sows and their litters were used to evaluate the effects of essential fatty acid intake on sow reproductive performance, piglet growth and survivability, and colostrum and milk composition. At approximately d 112 of gestation, sows were blocked by parity within farrowing room and randomly assigned to 1 of 4 experimental treatments. Lactation diets were corn-soybean meal-wheat-based and included 0.5 (Control) or 3% choice white grease (CWG), 3% soybean oil (SO), or a combination of 3% soybean oil and 2% choice white grease (Combination). Thus, sows were provided diets with low essential fatty acid (EFA; …

A meta-regression analysis was conducted to evaluate the effects of branched-chain amino acids (BCAA) in lactating sow diets on litter growth performance, sow body weight change, and sow feed intake. Thirty-four publications that represented 43 trials with similar dietary Lys, but varying BCAA were used to develop a database that contained 167 observations. Diets from each trial were reformulated using NRC nutrient loading values in an Excel-based spreadsheet. Significant predictor variables within three optimum equations developed for litter ADG included the count of weaned pigs per litter, NE, SID Lys, CP, sow ADFI, Val:Lys, Ile:Lys, and Leu:Val. The equations suggest …

The sow portion of the farrowing crate was maintained at a constant length and width of 7.4 and 2.0 ft, respectively. To form the treatments, crate width was adjusted accordingly, taking space away from one sow’s crate to give it to another allowing for 3 crate widths: 4.8 (small), 5.4 (medium), and 6.0 ft (large). This allowed for blocks of 3 crates, where each treatment was represented. …

Kansas Agricultural Experiment Station Research Reports
Two experiments evaluated the accuracy of individual computerized feed delivery systems for lactating sows (GESTAL Solo, JYGA Technologies Inc., St-Lambert-de-Lauzon, Quebec, Canada). The feeders volumetrically dispense feed based on rotations of a screw auger. In Experiment 1, 29 prototype feeders were used across 3 farrowing groups. On d 0, 1 feeder was selected to calibrate the computer system to the bulk density of the lactation diet. Feeders were programmed for 5 feeding periods per day with feeding period allowing up to 4 feed drops triggered by the sow. Sows activate a trigger within the feed bowl to receive a targeted …

Spinning Straw Into Milk: Can An All- Byproduct Diet Support Milk Production?, M. Hulett, C. Ylioja, T. Wickersham, B. Bradford
Spinning Straw Into Milk: Can An All- Byproduct Diet Support Milk Production?, M. Hulett, C. Ylioja, T. Wickersham, B. Bradford
Kansas Agricultural Experiment Station Research Reports
Ruminants are able to consume feeds that are unsuitable for humans and monogastric animals, and thus contribute to increased efficiency of our food systems. This study evaluated the performance of dairy cows consuming a diet comprised almost entirely of byproduct feeds, compared with cows consuming a typical lactation diet. The hypothesis was that the byproduct diet could support 80 lb/day of milk production. Although milk production and crude feed efficiency decreased compared to the typical diet, feed efficiency expressed as human-edible output per human-edible input increased for the byproduct diet. This study highlights the unique and important role played by …

Effects Of Dietary Fat Source On Performance Of Lactating Dairy Cows Fed A Pre-Mixed Concentrate, C. Ylioja, C. Abney-Schulte, Rick A. Stock, B. Bradford
Kansas Agricultural Experiment Station Research Reports
Inclusion of a pre-blended concentrate (OneTrak®, Cargill Inc., Blair, NE) in the total mixed ration (TMR) for dairy cows can simplify the daily mixing of dietary ingredients. A cow’s response to fat supplementation can be affected by other dietary ingredients; however, little is known about production responses to dietary fat in diets with high concentrations of non-forage fiber. This study evaluated cow performance in response to fat sources when the ration contained a pre-blended concentrate composed largely of a non-forage fiber source. Six pens of mid-lactation cows were studied; the addition of saturated fat (Energy Booster 100) and rumen-protected unsaturated …
