Characteristics Of Preblended Pork During Cooler Storage (1987), Curtis L. Kastner, Y I. Choi, Donald H. Kropf Jan 1987

Characteristics Of Preblended Pork During Cooler Storage (1987), Curtis L. Kastner, Y I. Choi, Donald H. Kropf

Kansas Agricultural Experiment Station Research Reports

Five pork carcasses were used to determine the effects of hot boning and various combinations of salt (0, 1.5, or 3.0%) and a phosphate mixture (0 or 0.5%) on bacteria, TBA (measure of fat rancidity), and pH values of preblended pork (preblends). In both HB (hot boned within 2 hr postmortem) and CB (conventionally boned at 24 hr postmortem) preblends, salt increased (P<.05) TBA values (indicates increased rancidity) and decreased (P<.05) growth of psychrotrophic bacteria, whereas phosphate increased (P<.05) pH and decreased TBA values. Salt levels could be reduced from 3.0 to 1.5% in preblends without storage problems, if phosphate (0.5%) was included. Phosphate (mixture pH 7.2) had little influence on microbial growth of preblends during cooler storage.; Swine Day, Manhattan, KS, November 19, 1987


The Effect Of Season On Response Of Growing-Finishing Pigs To Dietary Fat Levels (1987), G L. Allee, G R. Stoner, M E. Johnston, Jim L. Nelssen Jan 1987

The Effect Of Season On Response Of Growing-Finishing Pigs To Dietary Fat Levels (1987), G L. Allee, G R. Stoner, M E. Johnston, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

This experiment was conducted to examine the influence of season on the response of finishing pigs to practical levels of fat addition. A total of 378 pigs (average initial weight per trial ranging from 83 to 98 pounds) were utilized in four finishing trials conducted during time frames approximating the 4 seasons of the year. Groups of pigs were taken off trial as they reached market weight (230 pounds). There was no season x fat level interaction for any of the criteria measured. Therefore, it is concluded that season has essentially no effect on fat level response. Fat addition influenced …


Characteristics Of Frankfurters From Preblended Pork (1987), Curtis L. Kastner, Y I. Choi, Donald H. Kropf Jan 1987

Characteristics Of Frankfurters From Preblended Pork (1987), Curtis L. Kastner, Y I. Choi, Donald H. Kropf

Kansas Agricultural Experiment Station Research Reports

Five pork carcasses were used to determine the effects of hot boning and various combinations of salt (0, 1.5, or 3.0%) and a phosphate mixture (0 or 0.5%) on functional, processing, and storage characteristics of preblended pork (preblends). Although hot-boned (HB) preblends had superior functional properties compared to conventionally boned (CB) preblends, HB and CB frankfurters had similar characteristics. More (P(.05) myosin and actin (proteins that cause lean and fat particles to bind together) were extracted from HB than CB preblends. Addition of salt (1.5 or 3.0%) or phosphate (0.5%) generally increased myosin and actin extraction in both HB and …


Haemophilus (Actinobacillus) Pleuropneumoniae Infection In Germfree Piglets (1987), N V. Anderson, C A. King Jan 1987

Haemophilus (Actinobacillus) Pleuropneumoniae Infection In Germfree Piglets (1987), N V. Anderson, C A. King

Kansas Agricultural Experiment Station Research Reports

Germfree piglets rapidly develop pneumonia after Haemophilus pleuropneumoniae is inoculated into the lung, providing a basis of comparison for future studies of pneumonia in SPF and conventionally reared piglets.; Swine Day, Manhattan, KS, November 19, 1987


Protein Requirement Of Finishing Barrows And Gilts (110 To 230 Lbs) (1987), Robert H. Hines, B A. Koch, David A. Nichols, L M. Turlington, Robert D. Goodband Jan 1987

Protein Requirement Of Finishing Barrows And Gilts (110 To 230 Lbs) (1987), Robert H. Hines, B A. Koch, David A. Nichols, L M. Turlington, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

Eighty barrows and 80 gilts were fed diets containing four crude protein levels (16, 15, 14, and 13%) from approximately 115 lb to a market weight of 230-235 lb. Barrows and gilts were fed separately to determine their protein requirements during the finishing period. Performance traits (ADG, ADF, and F/G) of barrows and gilts were not significantly affected by increasing the protein content of the diet from 13 to 16%. However, barrows linearly decreased in fat thickness at the 10th rib as crude protein content in the diet was increased. Also, percent muscle increased linearly with increased protein for barrows, …


Estrous Expression Of Sows After Altered Suckling And Boar Exposure (1987), E A. Newton, Jeffrey S. Stevenson, Duane L. Davis Jan 1987

Estrous Expression Of Sows After Altered Suckling And Boar Exposure (1987), E A. Newton, Jeffrey S. Stevenson, Duane L. Davis

Kansas Agricultural Experiment Station Research Reports

In two different experiments, we studied the influence of: 1) separating litters from their dams (altered suckling) during the last 8 days of lactation, which included a change in housing and social interaction with other sows; 2) providing boar exposure (1 hr/d); and 3) parity on the ability of sows to come into heat during lactation and after weaning. Our studies indicated that: 1) 6 hr of altered suckling and 1 hr of boar exposure may shorten the interval to heat for sows that express estrus during lactation, but 3 hr of altered suckling and 1 h of boar exposure …


Minimizing Environmental Effects On Nutritional Needs Of Growing Finishing Pigs (1987), David A. Nichols Jan 1987

Minimizing Environmental Effects On Nutritional Needs Of Growing Finishing Pigs (1987), David A. Nichols

Kansas Agricultural Experiment Station Research Reports

Swine have a great ability to grow and reproduce in a variety of environments and facilities. This ability is documented by profitable production in both the most elaborate and the most simple facilities. Efficiency and profitability in environmental extremes are highly variable but performance level during environmental stress is generally less than maximum. The thermal environment strongly influences pig performance with air temperature having the primary effect. All too often, producers fail to consider the total environment of the pig. Air movement, humidity, and, in some instances, solar radiation contribute to how the pig feels. We must consider the total …
