Inosine 5’- Monophosphate Derived Umami Flavor Intensity Of Beef Determination By Electrochemistry And Chromatography, Kezia Virellia To
Theses and Dissertations
The umami sensation contributes to beef flavor and acceptability. Inosine 5’- monophosphate (IMP) was the most abundant nucleotide in meat known to impart umami taste which thus far had been overlooked in meat flavor studies. The objectives of this study were to determine the umami taste threshold of inosine 5'-monophosphate (IMP), the effects of spiking IMP on the sensory descriptive attributes of various USDA graded beef strip steaks, and to differentiate beef by IMP content using electrochemistry. USDA Prime, Choice, and Select steaks were spiked with 0.3 and 0.6 mM IMP and analyzed chemically and organoleptically. Liquid chromatography-mass spectrometry and …

Effects Of Extrinsic And Intrinsic Factors On Meat Quality And Muscle Biology Of Livestock, Yongjie Wang
Graduate Theses and Dissertations
In order to improve the meat quality of livestock, intrinsic and extrinsic factors that impact meat quality have been studied for a long time to optimize production quality. Nutrition, breed, and environment are the three most common factors to improve meat quality and muscle growth. The objective of this thesis is to perform a horizontal comparison of the effects of crude protein levels, breeds, and topsoil on the growth performance, muscle development, and meat quality of livestock, and also a longitudinal analysis using RNA-seq, RT-qPCR, and Western-blot to investigate the changes in genes and proteins related to muscle growth, and …
Prediction And Evaluation Of Breast Myopathy, Barbara De Almeida Mallmann
Prediction And Evaluation Of Breast Myopathy, Barbara De Almeida Mallmann
Graduate Theses and Dissertations
Broiler breast myopathies, including woody breast, white striping, and spaghetti breast, negatively impact the industry. Therefore, evaluation, prediction, and frequency of these muscle abnormalities on modern birds are important for decision making. Modern broilers are not highly active and often sit with the breast of the bird resting on the floor. Therefore, the first experiment was to promote bird movement and explore the impact on the breast myopathies. The movement was stimulated by human interaction (walking through pen) and higher light intensity so that birds walked around the pen more often throughout the day. The control group had normal low …
The Influence Of Chromium Supplementation On The Insulin Pathway, Carcass Traits, And Meat Quality Of Feedlot Steers, Heather Rode
The Influence Of Chromium Supplementation On The Insulin Pathway, Carcass Traits, And Meat Quality Of Feedlot Steers, Heather Rode
Electronic Theses and Dissertations
Chromium supplementation (Cr) can increase efficiency of growth in livestock by amplifying insulin signaling. Previous research showed Cr increases nutrient utilization and changes in muscle growth and fat deposition. Therefore, the objective of this research was to determine how Cr affects carcass traits, meat quality, and the insulin pathway in feedlot steers. Calf-fed steers were allotted to 0 ppb (CON) or 400 ppb Cr propionate (Cr400) for 210d in experiment 1. Two longissimus muscle (LM) biopsies were collected to examine protein abundance and gene expression after adaptation to a terminal implant and after adaption to ractopamine hydrochloride (RAC). A follow …

Kansas Agricultural Experiment Station Research Reports
Bull breeding soundness evaluations are often performed as a critical component of beef cow herd management to ensure that herd bulls have adequate semen quality, are physically capable of enduring the breeding season, and to determine the serving capacity per bull. Currently, there are approximately 30.3 million beef cows and 2.1 million bulls in the U.S. Depending on the breeding soundness evaluation failure rate, there are likely several hundred thousand bulls which will enter the beef market annually and a portion will be young bulls with the potential to be fed and sold to produce saleable meat of choice or …
Impact Of Algae Supplemented Diets Combined With Antioxidants On The Nutritional Profile, Quality Attributes, And Storage Stability Of Chicken Breast Meat, Rebecca G. Norcross
Impact Of Algae Supplemented Diets Combined With Antioxidants On The Nutritional Profile, Quality Attributes, And Storage Stability Of Chicken Breast Meat, Rebecca G. Norcross
Theses and Dissertations--Animal and Food Sciences
Consumers’ demands for ω-3 polyunsaturated fatty acids (PUFAs) are at all-time high. Algae, a common source of PUFAs, and antioxidants are both used as supplements in livestock feeds, are known to affect the overall quality of meat. To implement PUFA deposits into broiler meat, this study evaluated combining antioxidants and algae in broiler feed to enhance the breast meat quality. Broilers were fed diets supplemented with 50 IU Vitamin E or 200 g/ton EconomasE (EcoE, an antioxidant pack) plus 10 IU Vitamin E, with or without 0.5% algae extract (SP-1). The feed oil was partially oxidized soybean oil (POV: 86 …

The present study investigated the effects of the nutritional levels of diets on meat quality and related gene expression in Hainan black goat. Twenty-four goats were divided into six dietary treatments and were fed a concentrate-based diet with two levels of crude protein (CP) (15% or 17%) and three levels of digestive energy (DE) (11.72, 12.55 or 13.39 MJ/kg DM) for 90 days. Goats fed the concentrate-based diet with 17% CP had significantly (P < 0.05) higher average daily gains (ADG) and better feed conversion rates (FCR). The pH 24h value tended to decrease (P < 0.05) with increasing DE levels. The tenderness of Longissimus dorsi muscle (LD) and Semimembranosus muscle (SM) reduced with increasing CP levels (P < 0.05). With increasing DE levels, tenderness was increased (P < 0.05). The heart fatty acid-binding protein (H-FABP) mRNA expression levels in LD and SM increased with increasing DE levels (P < 0.05), but decreased with increasing CP levels (P < 0.05). The calpastatin (CAST) and μ-calpain mRNA expressions levels in LD and SM were affected significantly (P < 0.05) by CP and DE levels in the diet. Therefore, the nutritional levels of diets affect meat quality and expression levels of genes associated with meat quality in Hainan black goats.

One hundred seventy-seven pigs were used to determine the interaction effects of fasting and length of transport prior to harvest on pork muscle quality. The study design was a 2 × 2 × 3 factorial, which involved two genetic sources, fasting (F) or no fasting (N) of pigs 48-h prior to harvest, and three transport times (0.5, 2.5, or 8.0 h) on a semitrailer to the packing plant. Genetic source was a significant source of variation (P < 0.05) for most composition and muscle quality variables. Fasting reduced hot carcass weight 3.6% (P < 0.05), but length of transport did not affect hot carcass weight (P > 0.05). There were no differences (P > 0.05) in percent lean among fasting and transport treatments. Fasted pigs had higher longissimus dorsi (LD) ultimate …

Journal of the Department of Agriculture, Western Australia, Series 4
In Australia, a sheep ceases to be a lamb as soon as the eruption of its first permanent incisor teeth is evident. As part of a wider program to investigate a number of aspects of sheep meat eating quality, a project was undertaken to determine whether lamb eating quality would be compromised if sheep with partially erupted teeth continued to be classified as lamb.
Overall, the results indicated that meat from young sheep with partially erupted teeth was unlikely to be inferior in eating quality than the meat currently classified as lamb.

Agriculture reports
Growth potential of steers in the Pilbara - a summary. The trial was conducted over a range of conditions on three locations. The pasture type at Wyloo, the Ashburton River frontage, which is regarded as one of the most productive pasture types in the area, combined with conservative stocking, a fresh paddock and excellent seasonal conditions during 1995, gives us an indication of the District's potential. In extrapolating any of these data to other cases, consideration must be given to adjustment base

The Sheep Measles Control Programme, J B. White
Journal of the Department of Agriculture, Western Australia, Series 4
In the first seven months of 1968 Australia exported to the United States 17 747 tons of boned mutton; of this 2 198 tons, or 12.4 per cent, was condemned on arrival in that country.
The main cause of rejection was the presence of Cystkercus ovis cysts, the intermediate stage of the tapeworm Taenia ovis, of which the definitive host is the dog.
In 1969 the Western Australian Department of Agriculture decided to study the epidemiology of this disease.
This was the beginning of the work which would evolve into the 'Three Shire Control Programme'
