Some Behaviour Traits Observed On The Kıvırcık And Crossbred Lambs Raised In Intensive Conditions, Fevzi̇ Karaağaç, Mustafa Özcan, Türker Savaş Jan 2005

Some Behaviour Traits Observed On The Kıvırcık And Crossbred Lambs Raised In Intensive Conditions, Fevzi̇ Karaağaç, Mustafa Özcan, Türker Savaş

Turkish Journal of Veterinary & Animal Sciences

In this study, the behaviour responses of the crossbred lambs [F_2 (German Black-Headed Mutton x Merino) x F_1 (Chios x Kıvırcık)] were compared with the Kıvırcık lambs in intensive conditions and the effects of genotype, sex and observation period on the behaviours displayed were investigated. The data were collected from 10 (5 male + 5 female) Kıvırcık and 10 (5 male + 5 female) crossbred lambs, which were weaned at the age of 2-2.5 months. The effect of genotype was found significant on the behaviours of feed consumption (P < 0.01), activities towards the bedding material (P < 0.05), rumination (P < 0.01), lying (P < 0.01), oral stereotypic behaviours (OSB) (P < 0.01) and behaviours towards animal (BTA) (P < 0.01). Behaviours towards other animals and oral stereotypic behaviours in the crossbred lambs were 50% and 27% more than the Kıvırcık lambs, respectively. Significant differences in terms of the activities towards the bedding material (P < 0.05), rumination (P < 0.01) and lying (P < 0.01) behaviours were determined between the male and female lambs. It was seen that the male lambs were more active in the breeding area. The effects of observation period were found significant on feeding (P < 0.01), drinking (P < 0.01), rumination (P < 0.01), lying (P < 0.01), standing (P < 0.01), oral stereotypic behaviours (P < 0.01) and behaviours towards animals (P < 0.05). Although the crossbred lambs were more superior for fattening program in terms of live weight gains, they showed more abnormal behaviours (OSB and BTA), which are the signs of stress, in the limited breeding area, depend on the lessening of the area by the rise in their live weights.

Effects Of Ascorbic Acid On The Performance And Some Blood Parameters Of Japanese Quails Reared Under Hot Climate Conditions, Mehmet Avci, Muğdat Yertürk, Oktay Kaplan

Turkish Journal of Veterinary & Animal Sciences

The effects of ascorbic acid on the performance and some blood parameters of Japanese quails reared under hot conditions were investigated. Three hundred Japanese quails, 7 days of age, were randomly divided into one control and two experimental groups, comprising five replicates of 20 birds each. Ascorbic acid (500 and 1000 mg/kg) was given to the experimental groups. The body weight gain increased significantly (P < 0.05) in the group given 500 mg/kg of ascorbic acid until the fourth week. Feed consumption also increased (P < 0.05), depending on the quantity of ascorbic acid supplementation until the fourth week. However, ascorbic acid did not affect the concentrations of blood pH, PCO_{2}, sodium (Na), potassium (K), hematocrit (PCV), bicarbonate (HCO_{3}), or hemoglobin (Hb). In conclusion, 500 mg/kg of ascorbic acid may be added to the quail diet to prevent heat stress until the fourth week.

Aspergillosis And Gastric Impaction In An Ostrich, Azi̇z Arda Sancak, Jale Paracikoğlu Jan 2005

Aspergillosis And Gastric Impaction In An Ostrich, Azi̇z Arda Sancak, Jale Paracikoğlu

Turkish Journal of Veterinary & Animal Sciences

It is inevitable to encounter many diseases of ostriches in Turkey as a consequence of the rapid expansion of ostrich farming and flocks in this country. Aspergillus fumigatus was isolated from the lungs and air sacs of a 3-month-old, male, blue-neck ostrich. In postmortem examination, the ingestion of a large amount of gravel was noted. The accumulated gravel had led to an occlusion of the passage between the proventriculus and gizzard. This work appears to be the first report of aspergillosis and gastric impaction developing together and leading to death in an ostrich.

Effects Of Urea Or Urea Plus Molasses Supplementation To Silages With Different Sorghum Varieties Harvested At The Milk Stage On The Quality And In Vitro Dry Matter Digestibility Of Silages, Bi̇lal Keski̇n, İ. Hakki Yilmaz, M. Aki̇f Karsli, Hüseyi̇n Nursoy

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to evaluate the effects of 0.5% urea and 0.5% urea plus 4% molasses (on weight basis) addition to sorghum silages ensiled using 4 sorghum varieties (Grass II, Grazer, Gözde, and P-988) harvested at the milk stage. Plant materials were ensiled in 1-kg jars and the chemical composition, pH, organic acids, in vitro digestibility (IVDMD) and digestible dry matter yield (DDMY) of the silages were determined. Addition of urea and urea plus molasses to silages increased the crude protein ratio significantly (P < 0.01). However, the addition of urea plus molasses significantly decreased the neutral detergent fiber and acid detergent fiber contents of the silages. Additives significantly increased the pH values of the silages. The addition of urea and urea plus molasses to silages generally did not affect acetic or propionic acid content; however, the butyric acid content of the urea and urea plus molasses groups was higher than that of the control groups. IVDMD of all sorghum varieties decreased with the addition of urea and urea plus molasses. Additives did not affect DDMY. In conclusion, the addition of 0.5% urea and 0.5% urea plus 4% molasses to sorghum silages, harvested at the milk stage, improved the CP content of the silages, but they had no positive effect on silage quality, IVDMD or DDMY.

Concentrations Of Some Minerals In Cows With Retained Placenta And Abortion, Yaşar Akar, Hami̇t Yildiz

Turkish Journal of Veterinary & Animal Sciences

This study was undertaken to investigate the relationship between blood levels of Ca, Zn, Mg, K, and Na and the occurrence of retained placenta and abortion in cows. Serum samples from 34 cows were analyzed (18 with retained placenta, 10 without retained placenta (control), and 6 that had aborted). Ca and Zn levels in cows with retained placenta were significantly lower than those in the control group. The serum Zn levels of aborted cows were higher (P < 0.001) than those of cows with retained placenta. Cows in the control group and those with retained placenta were divided into subgroups based on age (3, 4-6, 7-9 years old), type of parturition (normal, dystocia), and sex of calves (male, female). The serum Ca concentration of 3-year-old cows with retained placenta was significantly higher (P < 0.05) than that of those 7-9 years old. It is concluded that lower serum Ca and Zn levels in cows may induce placenta retention.

This experiment was conducted to determine the feasibility of cuttlefish backbone as a new xenograft in the treatment of bone defects and its therapeutic effectiveness. Following the administration of general anaesthesia to 20 one-year-old male New Zealand rabbits, traumatic defective areas (5 mm in diameter) were experimentally induced at the proximal and distal metaphyses of both femurs. These defective areas (n = 80) were randomly assigned to be filled with cuttlefish backbone, spongious bovine graft (SBG), tricalcium phosphate (TCP) and demineralised bone matrix (DBM) in a complete randomised design. At the end of the 30-day postoperative experimental period, bone defects …

This study was carried out to investigate the effects of dietary vitamin C supplementation on some egg production traits and eggshell quality in Japanese quails reared under high ambient temperature. One hundred fifty-eight 11-week-old female Japanese quails were used. The birds were divided into 4 dietary treatment groups according to vitamin C levels as follows: control (basal ration), treatment I (basal ration + 150 ppm vitamin C), treatment II (basal ration + 250 ppm vitamin C) and treatment III (basal ration + 500 ppm vitamin C). The quails were housed for 9 weeks at high ambient temperature (34 ± 2 …
