The Effects Of Urea And Molasses Addition Into Corn Harvested At Early-Milk Stage On Silage Quality And Digestible Dry Matter Yield, Ni̇hat Denek, Suphi̇ Deni̇z Jan 2004

The Effects Of Urea And Molasses Addition Into Corn Harvested At Early-Milk Stage On Silage Quality And Digestible Dry Matter Yield, Ni̇hat Denek, Suphi̇ Deni̇z

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to evaluate the effects of the addition of 0.5% urea or 0.5% urea plus 4% (w/w) molasses into corn varieties (Rx-947, 33-94, Frassino, and Arifiye) harvested at the early-milk stage on silage quality, in vitro digestibility and digestible dry matter (DM) yield. The addition of urea into silage increased the CP content (P < 0,05). The neutral detergent fiber and acid detergent fiber contents of the control silages were 69.40 and 38.68 for Rx-947, 69.34 and 38.69 for 33-94, 62.67 and 34.93 for Frassino, and 64.35 and 37.04 for Arifiye (P < 0,05). The addition of urea or urea plus molasses into silage increased the silage pH in all varieties, except for Rx-947 (P < 0,05). The lactic, acetic, propionic and butyric acid contents of the silage samples were between 23.2 and 153.3, 7.8 and 23.4, 0.6 and 1.6, and 0.0 and 0.54 g/kg DM, respectively. The addition of urea or urea and molasses into Rx-947 and Frassino varieties and the addition of urea only into the 33-94 variety increased silage lactic acid levels. The addition of urea and molasses into Rx-947, Frassino and Arifiye varieties also increased silage acetic acid levels (P < 0,05). There was a significant difference only between the Frassino and Arifiye varieties on this parameter (P < 0,05). The addition of urea only into silage decreased DM digestibility; the addition of molasses with urea, however, eliminated this negative effect of urea on digestibilit in all varieties, except for Frassino (P < 0,05). Digestible DM yields of untreated silage were 863.68, 1142.43, 1044.43, and 1075.07 kg/decare (10 decares = 1 hectare) for Rx-947, 33-94, Frassino and Arifiye, respectively (P < 0,05). The digestible DM yield of untreated Rx-947 silage was significantly lower than those of the others (P < 0,05). It can be concluded that corn varieties harvested at the early-milk stage (20% DM) can be ensiled, and that urea and molasses can be used as silage additive to increase CP and energy content of silages.

A data set containing 2-year test day milk yield records was used. Random regression model solutions established with a covariance function (CF) approach was used. Persistence and lactation curve explanation performances of polynomial, Wilmink and Ali-Schaeffer curve definitions were compared for CF. When comparisons were made for R2 values, polynomial (0.9835) definition headed the list, followed by the Ali-Schaeffer curve (0.9534), and Wilmink curve (0.6023) definitions. Among the persistence predictions in respect of lactation orders, the Ali-Schaeffer curve provided predictions with the minimum variance, followed by the Wilmink and polynomial curve approaches. All of the curve definitions were in accord …

Effect On Aflatoxin Formation Of Different Storage Conditions In Tulum Cheese Inoculated With Aspergillus Parasiticus Nrrl 2999, Mustafa Gürses, Ahmet Erdoğan, Selahatti̇n Sert Jan 2004

Effect On Aflatoxin Formation Of Different Storage Conditions In Tulum Cheese Inoculated With Aspergillus Parasiticus Nrrl 2999, Mustafa Gürses, Ahmet Erdoğan, Selahatti̇n Sert

Turkish Journal of Veterinary & Animal Sciences

Tulum cheese was divided into 2 equal parts. One part was inoculated with 10^4 spores/g of aflatoxin-producing Aspergillus parasiticus NRRL 2999 strain. The other part, the control group, was not inoculated. All the samples were ripened in glass jars at 2 different temperatures (10 ± 1 and 20 ± 1 °C) and relative humidities (85 ± 2% and 95 ± 2%) and analyzed for aflatoxin formation on days 1, 15, 30, 45, 60 and 90 of storage using thin layer chromatography. Aflatoxins were determined in the inoculated samples after 15 days with incubation at 20 ± 1 °C, while they …

The Effects Of Processing Techniques On Microflora Of Roach (Rutilus Rutilus) And Whitefish (Coregenus Sp.), Fatma Arik Çolakoğlu Jan 2004

The Effects Of Processing Techniques On Microflora Of Roach (Rutilus Rutilus) And Whitefish (Coregenus Sp.), Fatma Arik Çolakoğlu

Turkish Journal of Veterinary & Animal Sciences

Two fish species, Rutilus rutilus and Coregenus sp., were processed using 4 techniques, and the effects of the processing were investigated on the bactarial flora of fish products, which is a crucially important criterion with regard to fish spoilage. A total of 85 fish were processed using smoked, fried, marinated and salad techniques. The microbiological features of these processed fish products were examined. For this purpose, the total number of aerobic bacteria and numbers of Enterobacter, Pseudomonas, Staphylococcus, Lactobacillus, Enterococcus and Bacillus, which are called "normal flora", and fungi that are known to influence the spoilage of fish were determined. …
