Turkish Journal of Veterinary & Animal Sciences

In this study, maize and legume intercropping were evaluated in terms of silage yield and quality. Maize (Zea mays L.''M'') was intercropped with soybean (Glycine max L. ''S'') and cowpea (Vigna unguiculata L. ''C'') as binary mixtues (maize + legume), and the seed rates were as follows: 100 + 0%, 75 + 25%, 50 + 50% and 25 + 75%. The harvested plants were chopped with the particle size of < 2, ensiled in 2 kg plastic jars and left fermentation at 25 ± 2 °C for 45 days. In this study, silage yield, dry matter ratio, pH value, crude protein ratio, acid detergent fiber, neutral detergent fiber, digestibility of dry matter, dry matter intake, total digestibil nutrient relative feed values, lactic acid, acetic acid, butyric acid, malic acid, citric acid, succinic acid, oxalic acid, potassium, phosphorus, calcium, and magnesium contents were determined. All the M + S mixtures showed high performance in terms of Flieg score and lactic acid content. The highest relative feed quality value was determined in the sole cowpea (156.4) and 25M + 75S% (148.5) mixture. As a result, intercropping maize with legumes resulted in superior silage quality without a reduction in yield.

Turkish Journal of Veterinary & Animal Sciences

An in vitro trial was conducted to evaluate the effects of different unsaturated fatty acids (UFA) sources plus crude glycerin (CGL) on gas production and rumen biohydrogenation (RBH). Incubated diet corresponded to diets containing corn silage (30%) and concentrate (70%) composed of corn, urea, mineral salts, CGL, and different UFA sources as follows: no additional fat (NAF), rumen protected fat (RPF), soybean oil, linoleic acid (LA) or alpha-linolenic acid (LN). Methane concentrations in LA and LN were lower compared to NAF (p < 0.001), but when CH4 was expressed as a proportion of total gas, NAF and RPF showed the greatest values among evaluated UFA sources (p = 0.001). 18:1 t11 concentration showed a faster increase from 0 to 1 h and a slower decrease from 1 to 36 h of incubation, irrespective of UFA source. A higher C18:1 t11 production rate was observed from 1 h to 5 h of incubation, where LA and LN have higher values compared to NAF and RPF diets (p < 0.001). Diets with a high content of LA may be efficient as a nutritional approach to reduce methane production and RBH, resulting in positive effects on vaccenic acid concentrations.

Special Issue: Shiga Toxin-Producing Escherichia Coli, Rodney A. Moxley

School of Veterinary and Biomedical Sciences: Faculty Publications

Globally, Shiga toxin-producing Escherichia coli (STEC) is an important cause of diarrheal disease, most notably hemorrhagic colitis, and post-diarrheal sequela, such as hemolytic-uremic syndrome (HUS) [1]. Cattle are a major reservoir of STEC, with approx- imately half of the cases in humans attributable to foodborne exposure [2]. Prevention of human illness has mainly been through food safety measures [2]. Despite extensive research, no other generally accepted and effective preventive measures or therapies for STEC infections in human patients are available [3]. Many questions remain about STEC virulence factors, pathogenesis, detection, and other aspects that necessitate a continua- tion of basic …

Estimating Wildlife Strike Costs At Us Airports: A Machine Learning Approach, Levi Altringer, Jordan Navin, Michael J. Begier, Stephanie A. Shwiff, Aaron M. Anderson

United States Department of Agriculture Wildlife Services: Staff Publications

Current lower bound estimates of the economic burden of wildlife strikes make use of mean cost assignment to impute missing values in the National Wildlife Strike Database (NWSD). The accuracy of these estimates, however, are undermined by the skewed nature of reported cost data and fail to account for differences in observed strike characteristics—e.g., type of aircraft, size of aircraft, type of damage, size of animal struck, etc. This paper makes use of modern machine learning techniques to provide a more accurate measure of the strike-related costs that accrue to the US civil aviation industry. We estimate that wildlife strikes …
