Best weight to market hogs?

One of the important, recurring decisions that each hog producer must make is the weight at which to sell hogs. The decision to sell hogs may be influenced by cost and availability of feed, anticipated market hog price changes, weather conditions, overcrowding or need for facilities, or the need for cash for unpaid bills. All of these factors play an intricate role in the...

Nursery growth performance of intact males and barrows

A total of 100 weanling pigs with an average initial body wt of 11.8 lb and average age of 17 d was used in a 38-d growth assay to determine the effect of castration on growth performance of nursery pigs. All pigs were fed the same Phase I, II, and III diets formulated to 1.6, 1.4, and 1.35% lysine, respectively. Data indicated no differences in growth performance between intact...

Comparison of two atrophic rhinitis vaccines for young pigs

Two farrowing groups (340 pigs) were used to evaluate two atrophic rhinitis vaccines (Atrobac III and Tocivac for the young pig. Both vaccines were effective, because no clinical evidence of atrophic rhinitis was observed for either treatment during the experiment. Although the swine herd had been observed in previous farrowing do have various degrees of conjunctivitis, none was...

Effects of diet manipulation on growth performance, carcass characteristics, and meat quality of intact male pigs

Castrates were predictably less efficient, had greater ADFI, and tended to have more BF than contemporary boars. Castration decreased detection of boar taint, but alterations of dietary CP, pH, and antimicrobial level from 225 to 276 lb had no effect on sensory panel perception of odor from fat of intact males.; Swine Day, Manhattan, KS, November 19, 1998

Effect of mixing on performance of finishing swine

Two feeding trials were conducted to evaluate the effect of mixing finishing pigs on subsequent performance. Growth rate of heavier pigs was reduced 15-35% in the two weeks after mixing when compared to the non-mixed pigs. This reduction in weight gain resulted in a significant difference in average daily gain overall for pigs mixed at 5 weeks compared to non-mixed pigs. An 8...

Response of varying weight groups of finishing pigs to antibiotic supplementation

Two feeding trials involving a total of 320 head of finishing pigs were used to evaluate the effect of feeding an antibiotic to three groups selected from within a farrowing group. Pigs were divided by weight into group A (heaviest 50%), group B (25-50%) and group C (lightest 25%). Each group was assigned treatments of either 4 weeks of 100 gm of tylan-sulfa followed by 4 weeks...

Sustained effects of porcine somatotropin administered during the growing period on growth and carcass characteristics of finishing pigs

Forty six barrows were fed a common diet after completing a 35 d growth trial in which 50% received 5 mg/d of pST and the other 50% a placebo injection. At the conclusion of the growing trial (130 lb), the pST-injected pigs were leaner (22%) and yielded carcasses with larger longissimus muscle area (21 %). However, pigs fed to a slaughter weight of 225 lb yielded carcasses that...

Use of whey protein concentrate, dried buttermilk, and porcine plasma protein to replace dried skim milk in diets for weanling pigs

One hundred thirty-two weanling pigs, with an average age of 19 d and average weight of 8.4Ib, were used in a 28-d growth assay to determine the effects of replacing dried skim milk (DSM) with dried whey protein concentrate (WPC), dried buttermilk (DBM), and spray-dried porcine plasma (SDPP). Treatments were 1) 20% DSM20% dried whey-based control, 2) WPC used to replace the DSM...

Extruded sorghum and soybeans for nursery pigs

Two experiments were conducted to determine the effects of extruding sorghum and soybeans for weanling pigs. The first experiment involved 66 piglets with an average age of 19 d and average weight of 10.8 lb. Two diets were fed in meal form. Treatment 1 was ground sorghum mixed with extruded soybeans, and Treatment 2 was prepared by extruding the mixture of ground sorghum and...

Effects of feeder design and pelleting on growth performance and water use in finishing pigs

Pigs fed from wet-dry feeders had 4% greater ADG with 50% less water usage than those consuming feed from dry feeders. Pelleting diets improved F/G by 4% compared to meal diets. However, the benefits of pelleting were primarily when a dry feeder was used, with little evidence to support use of both pelleting and wet/dry feeders for finishing pigs.; Swine Day, Manhattan, KS...

Wheat gluten and spray-dried plasma protein blends for nursery pigs

Using a 50:50 blend of spray-dried plasma protein (SDPP):spray-dried wheat gluten (WG) (i.e., with each as approximately 4% of the diet) gave the greatest ADG and ADFI, while reducing diet costs compared to the control diet (i.e., 8% SDPP). Even with a slight decrease in efficiency of gain, the marked decrease in diet cost will yield better cost of gain with a 50:50 blend versus...

Sunflower oil seeds in nursery pig diets

Two hundred forty pigs were used to evaluate the use of various amounts (0, 10, 15, 20, 25%) of black sunflower oil seeds in weanling pig diets. After 14 days, no significant differences were found between any of the dietary treatments in feed intake (FI), average daily gain (ADG), or feed efficiency (F/G). At the conclusion of the 5-wk study, no differences were found in FI, ADG...

Effects of raw soybeans, roasted soybeans, and soybean oil on finishing pig performance

Two trials were conducted to evaluate the effects of raw soybeans, roasted soybeans, and soybean oil on finishing pig performance. In trial 1 pigs were fed a low protein control diet containing 7.5% soybean meal and synthetic lysine. Raw soybeans were added at levels of 8.75, 11.90, 15.05, and 18.20% of the diet. The raw soybean additions replaced the synthetic lysine and part of...

Wet vs. dry ad libitum feeding of growing-finishing swine

Two hundred and twenty-four growing-finishing pigs were used to evaluate wet vs. dry ad libitum feeding utilizing the Pride of the Farm Maxima®feeder. Growth rate, average daily feed intake, and feed/gain were the same for those pigs fed with feeders having water nozzles in the trough (wet) or (Finishing, Wet vs. Dry) without the nozzles in the trough of the feeder (dry).; Swine...

Supplementing day-old pigs with bovine colostrum or milk replacer

Seventy-five litters of newborn pigs from gilts were given either 20 cc of bovine colostrum or 20 cc of milk replacer through a stomach tube, and their weaning weight, scouring, and survival were compared with those of newborn pigs that were not treated. Results were broken down by birth weight groups: small-less than 2.3 lb.; medium-2.3 to 2.9 lbs.; large-3.0 lbs. and over. No...

Hard wheat compared to soft wheat for finishing swine

Three feeding trials were conducted to compare soft winter wheat with hard winter wheat for finishing swine. In each trial, soft wheat diets supported weight gains and feed/gain ratio equal to those observed for pigs fed hard winter wheat diets. Both soft and hard wheat diets were compared with milo basal diets resulting in similar performances and reaffirming that wheat can...

Effect of various anthelmintics on growing-finishing swine reared on dirt lots

Two trials involving 262 pigs were conducted to evaluate five worming programs for growing-finishing pigs fed on dirt lots heavily infected with roundworm (Ascarid) eggs. The control pigs (no anthelmentic) were compared in performance (ADG, F/G) and lung liver lesions at slaughter with pigs that received ivermectin on day 1 or day 28, pyrantel tartrate for the first 28 days, or...

Extrusion of sorghum, soybean meal, and whole soybeans improves growth performance and nutrient digestibility in finishing pigs

One hundred forty-four finishing pigs (124 lb avg initial wt) were used to determine the effects of extruding sorghum, soybean meal (SBM), and whole soybeans on growth performance and nutrient digestibility. Treatments were: 1) control diet with ground sorghum, SBM, and soybean oil; 2) diet 1 with the ground sorghum, SBM, and soybean oil blended and extruded; 3) sorghum and whole...

One hundred forty-four finishing pigs (124 lb avg initial wt) were used to determine the effects of extruding sorghum, soybean meal (SBM), and whole soybeans on growth performance and nutrient digestibility. Treatments were: 1) control diet with ground sorghum, SBM, and soybean oil; 2) diet 1 with the ground sorghum, SBM, and soybean oil blended and extruded; 3) sorghum and whole...
