Comparison Of In Vitro Dry Matter Degradation Of Four Maize Silages Using The Menke Gas Production Method, Adem Kamalak, Yavuz Gürbüz, Heather Finlayson

Turkish Journal of Veterinary & Animal Sciences

Four maize silages from the UK and France were evaluated using the gas production method to estimate the rate and extent of dry matter degradation in vitro. There were significant differences in gas production after 17 h incubation. The silages showed similar times to produce 50, 95 and 100% of total gas production, whereas the lag time for Ema was significantly (P < 0.001) lower than that for Volgate. The potential gas production value (a + b) for Nancis was significantly (P < 0.05) lower than that for Volgate. There was a significant correlation (r = 0.996, R^2 = 90.71, P < 0.001) between gas production and total VFA production. There were considerable differences in the fermentability of carbohydrates between different maize silages. Nancis and Ema had more readily fermentable carbohydrate, which yielded high propionate production and a shorter lag time. 6196 and Volgate had more slowly fermentable carbohydrate, which did become available to microorganisms but after a longer lag time.

The Effect Of Concentrate Feeding Levels On The Postweanining Performance Of Holstein Friesian Calves, Mete Yanar, Olcay Güler, Bahri̇ Bayram Jan 2002

The Effect Of Concentrate Feeding Levels On The Postweanining Performance Of Holstein Friesian Calves, Mete Yanar, Olcay Güler, Bahri̇ Bayram

Turkish Journal of Veterinary & Animal Sciences

The influences of different levels of concentrate on the growth characteristics of Holstein Friesian calves reared under an original calf-rearing program were investigated in this study. Forty-one new-born calves (20 male and 21 female) were allocated to the four concentrate groups: 2, 2.5, 3 kg/calf and ad libitum. The calves were weaned at 5 weeks of age, and the trial lasted for 6 months. The results with regard to weights at 6 months of age revealed that an increasing amount of concentrate supplementation resulted in a significantly (P < 0.01) higher live weight. Furthermore, daily weight gains between birth and 6 months of age was also significantly higher (P < 0.01) in the ad libitum group than in the 2, 2.5 and 3 kg/day groups. The highest overall gains in body measurements, for example body length and heart girth, were obtained from calves fed concentrate ad libitum. However, feed efficiency ratios were not significantly influenced by the various amounts of concentrate offered to calves. The overall results suggest that the appropriate level of concentrate for the new calf-rearing program should be ad libitum.

The Effect Of Long-Term Supplemental Dietary Cadmium On Lipid Peroxidation And The Antioxidant System In The Liver And Kidneys Of Rabbits, Ebru Beytut, Mesut Aksakal Jan 2002

The Effect Of Long-Term Supplemental Dietary Cadmium On Lipid Peroxidation And The Antioxidant System In The Liver And Kidneys Of Rabbits, Ebru Beytut, Mesut Aksakal

Turkish Journal of Veterinary & Animal Sciences

We investigated the effects of chronic exposure to dietary cadmium (Cd) on the levels of lipid peroxidation (LPO) and reduced glutathione (GSH) associated with activities of glutathione peroxidase (GSH-Px) and the catalase (CAT) enzyme in the liver and kidneys of rabbits. Twenty 10-month-old clinically healthy New Zealand white rabbits (10/group) of 3545 ± 250 g average body weight were used. The control group was allowed to take food and tap water ad libitum, while the experimental group was given tap water containing 200 ppm CdCl_2/L for 28 weeks. Lipid peroxidation contents increased significantly in the liver (p < 0.001) and kidneys (p < 0.005) of Cd-treated rabbits. Glutathione levels decreased significantly in both the liver (p < 0.001) and the kidneys (p < 0.005) of the experimental group. Cadmium treatment caused a significant decrease in the activities of GSH-Px and CAT in the liver (p < 0.001, p < 0.01) and kidneys (p < 0.005, p < 0.1) of the rabbits. These results indicated that a Cd-induced increase in LPO was associated with reductions in GSH-Px and CAT enzyme activities, and in GSH levels in the liver and kidneys of rabbits.

Turkish Journal of Veterinary & Animal Sciences

Seasonal changes in serum concentrations of the testosterone in males, 17\beta-estradiol in females and triglyceride and cholesterol in both sexes of Capoeta capoeta umbla were determined. Peak concentrations of testosterone (2.828 ± 0.278 ng/mL) and 17\beta-estradiol (3.182 ± 0.116 ng/mL) occurred in May. The concentrations of testosterone and 17b-estradiol were significantly correlated with the gonadosomatic index in both sexes. After the spawning period, steroid hormone levels significantly diminished (P < 0.05). The triglyceride concentration was highest in April (607.611 ± 30.146 mg/dL). The serum cholesterol level showed a rising trend until April and reached peak values during this month (393.000 ± 8.991 mg/dL). In the spawning month (May), a significant decrease was observed in triglyceride and cholesterol concentrations (P < 0.05). These results suggest that seasonal changes in both serum lipids and steroid hormones were associated with reproductive activity in C. c. umbla.

The aim of this study was to determine the effects of progesterone and testosterone hormones on the hyaluronidase activities of serum and semen and on sperm characteristics in sheep. Thirty healthy Akkaraman sheep were used. The progesterone and testosterone were injected intramuscularly at the rate of 0.5 mg/kg and 5 mg/kg, respectively. Then the blood and semen samples were obtained from the sheep at 1, 2, 4, 24, 48, 72 and 168 h. The serum hyaluronidase activities of ewes and rams in progesterone and testosterone groups increased significantly (p < 0.01, p < 0.001) when compared with the control groups at all times. Additionally, there were significant (p < 0.001) increases in the levels of semen hyaluronidase activity in the progesterone group except at 4 h. Furthermore, semen hyaluronidase activities in the testosterone group were detected to decrease significantly (p < 0.01) in comparison with the control rams except at 4 h. The use of progesterone and testosterone caused a significant (p < 0.05, p < 0.01) increase in spermatozoa motility, respectively. However, sperm concentrations were determined to decrease significantly (p < 0.01, p < 0.001) in both groups. Although the values for semen volume decreased significantly (p < 0.05, p < 0.01) in the progesterone group, the same values were observed to increase significantly (p < 0.01) in the testosterone group except at 48 h when compared with the control groups. The results of this study showed that there were no significant correlations between semen hyaluronidase activities and sperm characteristics. In conclusion, the use of both hormones did not have any deleterious effects on hyaluronidase activities but for the semen samples in the testosterone groups. However, progesterone and testosterone hormones cause harmful effects on the fertilization ability of rams due to decreased sperm concentration values.

In this study, the capture efficiencies and catch rates of three different traps were compared for the blue crab Callinectes sapidus in Beymelek Lagoon, Antalya, Turkey. All gear was used simultaneously and in the same habitats. The mean catch per unit effort (CPUE) was determined to be significantly higher for hoop nets than for traps. Gear effectiveness was examined by comparing CPUE (CPUE as number of crab per trap per haul, and g per trap haul), mean weight of individual crabs, catch composition and width frequency distributions of the blue crab for each gear.

Characterisation Of An Exopolysaccharide Preventing Phage Adsorption In Lactococcus Lactis Subsp. Cremoris Ma39, Mustafa Akçeli̇k, Pinar Şanlibaba Jan 2002

Characterisation Of An Exopolysaccharide Preventing Phage Adsorption In Lactococcus Lactis Subsp. Cremoris Ma39, Mustafa Akçeli̇k, Pinar Şanlibaba

Turkish Journal of Veterinary & Animal Sciences

Lactococcus lactis subsp. cremoris strain MA39 produces an extracellular polysaccharide containing rhamnose, glucose and galactose. A 16.5 kb plasmid encoding exopolysaccharide production in MA39 was determined by plasmid curing experiments. Phage adsorption assays showed that four different lactococcal phages were adsorbed to MA39-40; only the 16.5 kb plasmid cured an exopolysaccharide non-producing mutant of strain MA39, with high efficiency (93.2-98.5%) while adsorption of these phages was completely inhibited in the wild type strain MA39. These results suggest that exopolysaccharide prevents phage adsorption by masking phage receptor sites.

Turkish Journal of Veterinary & Animal Sciences

Fish were exposed to three different sublethal doses in order to determine the effects of Cypermethrin on some biochemical parameters (Ca-Calcium, P-Phosphorus, Na-Sodium and TP-Total Protein) of rainbow trout (Oncorhynchus mykiss). After 15 days exposure, Ca and P decreased, while TP and Na took various values depending on the doses of synthetic pyrethroid.
