Kansas Agricultural Experiment Station Research Reports
Bovine respiratory disease is the most common and costly disease in the beef industry. Calves affected by bovine respiratory disease have a 53-lb decrease in finished weights and decreased quality grades compared with healthy cattle. Many stressors influence post-arrival health and nutrient intake, including weaning, marketing, transportation, co-mingling, genetics, previous nutrition, and health history. These stressors can negatively affect the immune system at a time when the animal is more likely to be exposed to infectious agents within the bovine respiratory disease complex. Feed intake by stressed calves is low, and low nutrient intake likely increases the negative effects of …

Mga And Growth Promotants Administered To Beef Feedlot Heifers Have No Effect On Subsequent Oocyte Quality Or In Vitro Embryo Production (2012), N. Miller, David M. Grieger, Karol E. Fike
Kansas Agricultural Experiment Station Research Reports
Beef feedlot heifers have the potential to serve as viable donors of oocytes post-slaughter for in vitro embryo production. Oocyte quality is a critical factor affecting the success of in vitro embryo production and can be influenced by factors such as age and reproductive status, ovarian follicle size, and nutritional status of the donor female. In a conventional feedlot setting, heifers are typically administered steroid-based growth promotants and fed melengestrol acetate (MGA) for suppression of estrus, which increases circulating concentrations of reproductive steroids, particularly estradiol. The effects of these management practices on oocyte quality and numbers are unknown. The purpose …

Kansas Agricultural Experiment Station Research Reports
Fixed-time artificial insemination is an effective management tool that reduces the labor associated with more conventional programs that require detection of estrus. The 7-day CO-Synch + controlled internal drug release (CIDR) insert protocol has been shown to effectively initiate estrus and ovulation in cycling and non-cycling suckled beef cows, producing pregnancy rates at or greater than 50% in beef cows. The gonadotropin- releasing hormone (GnRH) injection that begins the CO-Synch + CIDR program initiates ovulation in a large proportion of cows, particularly anestrous cows. The CIDR, which releases progesterone intravaginally, prevents short estrous cycles that usually follow the first postpartum …
Feeding Crude Glycerin Decreases Fecal Shedding Of E. Coli O157:H7 In Growing Cattle (2012), C. Aperce, James S. Drouillard
Feeding Crude Glycerin Decreases Fecal Shedding Of E. Coli O157:H7 In Growing Cattle (2012), C. Aperce, James S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Crude glycerin is a byproduct of ethanol production and is used as a carbohydrate source for cattle feed. Glycerin levels in previous studies have ranged from 0 to 20% of diet dry matter, and concentrations of 8% or less generally improve feedlot performance. At even low levels of glycerin, however, the activity of cellulolytic bacteria is depressed, ultimately leading to poorer fiber digestion. This observation suggests that glycerin may affect a specific population of bacteria in the gut. Crude glycerin can account for 8 to 10% of the weight of dried distillers grains with solubles, because it is one of …

Tenderness is one of the most important factors affecting consumers' perceptions and acceptance of palatability. Tenderness is affected by both myofibrillar proteins and connective tissue content and quality. Both marbling and carcass maturity can have a significant effect on beef palatability, with higher consumer sensory scores generally given to USDA Choice loin steaks than to Select steaks for tenderness, juiciness, and overall palatability. Endpoint temperature can also have a significant effect, with higher endpoint temperatures generally decreasing palatability. Aging beef is a common practice in the meat industry because it increases tenderness and flavor development. The meat industry generally utilizes …

Kansas Agricultural Experiment Station Research Reports
Producers have adopted marketing strategies such as topping to help reduce economic losses from weight discounts at the processing plant. Despite adopting these strategies, producers are still missing target weights and incurring discounts. One contributing factor is the error of sampling methods that producers use to estimate the mean weight of the population to determine the optimal time to top pigs. The standard sample size that has been adopted by many producers is 30 pigs. Our objective was to determine the best method for selecting 30 pigs to improve the accuracy and precision of estimating the mean pig weight of …

Kansas Agricultural Experiment Station Research Reports
Fifteen trials were used for meta-analyses comparing the effects of conventional dry (CD) and wet-dry (WD) feeders on growth performance, carcass traits, and water usage of growing-finishing pigs. The meta-analysis indicated that pigs fed with WD feeders consistently had greater (P<0.01) ADG (0.09 lb/d) and ADFI compared with those fed with CD feeders; however, although highly variable, no overall difference (P = 0.93) was observed in F/G. As a result of improved growth rate, final BW and HCW of pigs fed with WD feeders was 3.2% greater (P<0.01) than when fed with CD feeders. For carcass traits, backfat was greater (P<0.01) and percentage lean was lower (P<0.01) in pigs fed with WD feeders compared with those fed with CD feeders. Carcass yield and loin depth did not differ (P>0.14) among feeder types. Water usage for pigs fed with WD feeders was 0.4 gal/pig/d less (P = 0.02) than for pigs using CD feeders. Growing-finishing pigs fed with WD feeders had increased growth rate, feed intake, final BW, and HCW, but deposited more fat as indicated by greater backfat and lower percentage lean.; Swine Day, Manhattan, KS, November …0.01)>

Carryover Effects Of Crude Glycerin Fed During The Growing Phase On Finishing Cattle Performance And Carcass Characteristics, C. C. Aperce, J. S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Crude glycerin is a byproduct of biodiesel production, and its use as a feedstuff for cattle has expanded in the last decade due to increased availability and favorable pricing compared with other energy concentrates such as cereal grains. Incorporation of glycerin into cereal-based finishing diets, at levels up to 8%, has been shown to improve cattle performance; however, it decreases activity of cellulolytic microorganisms in the rumen, ultimately decreasing fiber digestion. Most of the studies conducted to date have evaluated glycerin in finishing diets that contain relatively small amounts of fiber, but little is known of its value as an …

Consumers are not able to estimate tenderness, juiciness, or flavor when selecting beef cuts at retail stores. Instead, they rely on color as one of the major criteria to select beef cuts. During refrigerated display, fresh meat color changes and consumers discriminate against discolored meats. Meat items with discoloration must be discounted or discarded, leading to up to $1 billion in revenue loss nationally for the meat industry. Lighting type and intensity have a major impact on the appearance and shelf life of fresh beef in refrigerated retail display.

Morbidity reduces performance and quality grade, but the effects of morbidity on quality grade independent of its effect on carcass fatness are rarely documented. As feedlot cattle fatten, a greater proportion of their daily carcass gain goes to fat deposition, and greater carcass fat is consistent with greater marbling score. Higher-grading cattle are often assumed to have reduced feedlot performance. Objectives of this research were to document the impacts of various animal and non-animal factors on feedlot average daily gain, health, and carcass traits in Angus steers and to correlate quality and yield grade components of carcass with live performance.

Foodborne illness from Escherichia coli O157:H7 is a major concern for the food industry. Contamination of food products can occur at slaughter by contact with hide or feces. Limiting E. coli O157:H7 shedding is important to prevent outbreaks. Previous studies have demonstrated a relationship between stress and levels of pathogens shed in feces. During transport to the slaughterhouse, animals are subjected to large amounts of stress. This stress could increase shedding of E. coli O157:H7 prior to slaughter, and in so doing increase the risk of contamination of beef products by contact with hides or feces. Our objective in this …

Sericea lespedeza (Lespedeza cuneata) is a noxious weed that infests approximately 600,000 acres of native range in Kansas. Intake of sericea lespedeza by grazing beef cattle is poor due to the presence of condensed tannins in the plant. Condensed tannins reduce protein digestion by beef cattle and may also decrease plant palatability because of their astringent nature. Prolific seed production, in combination with little or no grazing pressure, has contributed to the rapid spread of sericea lespedeza in the Flint Hills. Increasing grazing pressure on sericea lespedeza may reduce seed production and slow its advance; however, the presence of condensed …

Adequate dietary intakes of trace minerals are thought necessary to maximize cow reproduction, calf health, and calf performance. Diets grazed by beef cattle are generally deficient to marginal in copper (Cu), manganese (Mn), selenium (Se), and zinc (Zn) concentrations; therefore, these trace minerals are usually added to the diet in supplement form. The most widely used means of trace-mineral supplementation for grazing cattle is selffed, salt-based, loose mineral supplements. Although cattle do not balance their mineral needs when consuming a self-fed mineral supplement, usually no other practical way of supplying mineral needs exists under grazing conditions. The greatest limitation to …

A total of 1,100 nursery pigs (PIC C-29 × 359, initially 15.0 lb BW) were used in a 42-d growth trial to determine the effects of increasing soybean hulls (10 or 20%) and soybean hull particle size (unground or ground) in nursery pig diets fed in both meal and pelleted forms. The average particle size of the unground and ground soybean hulls were 617 and 398 μ, respectively. Pens of pigs (5 barrows and 5 gilts) were balanced by initial BW and randomly allotted to 1 of 8 treatments with 11 replications per treatment. A 2-phase diet series was used …
