Effects Of Barley Diets With Distillers Grains Plus Solubles On Feedlot Performance And N And P Balance, Erin M. Hussey, Galen E. Erickson, Robert E. Peterson Peterson, Luis O. Burciaga-Robles

Nebraska Beef Cattle Reports

Effects of barley starch:NDF ratio and DDGS inclusion on feedlot performance, carcass characteristics, and N and P mass balance were evaluated in a commercial feedyard in Alberta, Canada. Yearling heifers were assigned randomly at reimplant to four treatments (0 or 20% DDGS and LOW or HIGH starch:NDF barley). Feeding LOW starch:NDF barley improved feedlot performance and increased N retention. Feeding 20% DDGS increased DMI, had a slight negative impact on F:G, and increased N and P losses.

Grazing Supplementation And Subsequent Feedlot Sorting Of Yearling Cattle, Kelsey M. Rolfe, William A. Griffin, Terry J. Klopfenstein Klopfenstein, Darrell R. Mark, Galen E. Erickson, Dennis E. Bauer

Nebraska Beef Cattle Reports

Steers fed (0.6% BW) modified distillers grains plus solubles on the ground had increased ADG and BW at the end of summer grazing and were more profitable. Supplemented steers were fed 24 fewer days to reach feedlot harvest goal, had greater LM area, and lower marbling. Steers sorted on feedlot entry BW had increased HCW, marbling, and YG, but percentage overweight carcasses and profitability were similar. Steers supplemented during summer grazing had $11.80/ animal greater overall profit.

Nebraska Beef Cattle Reports

Beef ribeye rolls, strip loins, and top sirloin butts were aged for 14 days and then blast or conventionally frozen and slow or fast thawed, or were fresh, never frozen and aged for 14 days or 21 days (n = 270). Thawing method affected purge loss and tenderness, and freezing method had a minimal effect. Neither freezing nor thawing methods had an effect on sensory tenderness, and minimal effects on the other sensory attributes. It is possible to freeze and thaw beef subprimals and for the meat to be comparable in tenderness and sensory attributes to fresh, never frozen meat.

Statistics Used In The Nebraska Beef Report And Their Purpose Jan 2012

Statistics Used In The Nebraska Beef Report And Their Purpose

Nebraska Beef Cattle Reports

The purpose of beef cattle and beef product research at UNL is to provide reference information that represents the various populations (cows, calves, heifers, feeders, carcasses, retail products, etc.) of beef production. Obviously, researchers cannot apply treatments to every member of a population; therefore, they must sample the population. The use of statistics allows researchers and readers of the Nebraska Beef Report the opportunity to evaluate separation of random (chance) occurrences and real biological effects of a treatment. Following is a brief description of the major statistics used in the beef report. For a more detailed description of the expectations …

Effects Of Cold Stress During Transportation On Hatchability And Chick Quality Of Broiler Breeder Eggs, Ahmad Salahi, Mozhdeh Moosanezhad Khabisi, Abbas Pakdel, Ali Baghbanzadeh

Turkish Journal of Veterinary & Animal Sciences

In this experiment 72,000 broiler breeder eggs (Ross 308 strain) collected from 36-week-old flocks were subjected to cold stress during transportation. Eggs were allocated to 4 temperature groups (treatments): 1.2 °C, 1-2 °C, 2.5-3.9 °C, 4-6 °C, and a control group, 21-22 °C. Each treatment had 14,400 eggs, and data were analyzed in a completely randomized design. The results of this study showed that cold stress had a significant effect on percentage of egg weight loss (P < 0.001), and minimal egg weight loss occurred in the control group. The percentage of exploders and early hatched chicks and chick weight were higher in the below zero temperature treatment than the other groups (P < 0.01). Cold stress had a significant effect on chick length, hatchability, and the hatching of fertile eggs (P < 0.001). The effects of cold stress on chick yield and body weight uniformity were significant (P < 0.01). The effect of cold stress on hatchery byproduct efficiency was significant (P < 0.001), but did not affect fertility. Cold stress also had significant effects on early (1-8 days), middle (9-17 days), and late mortality (20-21 days); total embryo mortality; and exposed brain. Ectopic viscera was significant (P < 0.001), and most mortality was observed in below 4 °C treatments. Total percentages of malpositions and deformity (P < 0.001) and egg contamination at 1-9 days (first stage) and 10-21 days (second phase) were affected by cold stress (P < 0.001). Cold stress also had a significant impact on the number of cull chicks; percent of string navel, button navel, total string, and button; omphalitis; full body cavity; red hocks; dehydration; dirty chickens; and stubby down. Cold stress affects performance during incubation and overall chick quality.

Turkish Journal of Veterinary & Animal Sciences

This study was conducted to evaluate the effects on sperm motility and abnormality in ram semen extended with skimmed milk (M), sodium citrate (SC), Tris (T), and Bioxcell® (B) after storage in liquid form at 4 °C and in frozen form. Ejaculates were collected from 3 Akkaraman rams by artificial vagina twice a week during the non-breeding season. After pooling, each pooled ejaculate was split into 4 equal aliquots and diluted with skimmed milk (M), sodium citrate (SC), Tris (T), and Bioxcell® (B) extenders. Sperm motility was significantly higher (P < 0.05) in M compared with B, SC, and T on the first and second days (48 h) of storage. With regard to the percentage of total abnormal spermatozoa, the results in M were different from (P < 0.05) from those of SC and T on the first day (24 h) of storage but no different from B. Differences among extenders were found to be significant post-thawing for spermatozoa motility and the percentage of total abnormal spermatozoa. The total abnormality of semen diluted with M was significantly lower than that observed in the other extenders. Consequently, it was found that skimmed milk was better than the other extenders in terms of the sperm parameters evaluated during liquid storage and post-thaw.

The tiger population that once inhabited the Korean peninsula was initially considered a unique subspecies (Panthera tigris coreensis), distinct from the Amur tiger of the Russian Far East (P. t. altaica). However, in the following decades, the population of P. t. coreensis was classified as P. t. altaica and hence forth the two populations have been considered the same subspecies. From an ecological point of view, the classification of the Korean tiger population as P. t. altaica is a plausible conclusion. Historically, there were no major dispersal barriers between the Korean peninsula and the habitat of …
