Estimating factors affecting wheat marketing efficiency using tobit model

Abstract: This study was aimed to measure marketing efficiency and study important factors affecting , using TOBIT qualitative response model for wheat crop in Salahalddin province. Results revealed that independent factors such as (marketing type, crops duration in the field, average marketing cost, distance between farm and marketing center, and average productivity) had an impact on wheat marketing efficiency. This impact varied in size and direction due to value of parameters. Values of marketing efficiency fluctuated within cities and towns in the province. The average value on the province level was 76.75%. This study was recommended developing marketing infrastructures which is essential to efficiency increases. In addition, it is important to decrease routine administrative procedures in governmental marketing institutions and establish marketing centers, even if they will be temporary, in harvesting and marketing period near the production areas.

Effect of dietary protected lysine supplementation on milk yield, composition and some blood and rumen parameters in local ewes

Abstract: This study was aimed to evaluate the effect of supplementing rumen protected lysine on milk production, composition and some blood and rumen parameters. Nine local ewes were assigned into three groups (3 ewes for each) and were allocated into 3x3 Latin-square design. The first group (control) was fed concentrate diet. The second group (F-LYF) was fed the control diet and supplemented with free lysin (3g/ewe/day). The third group (P-LYS) was fed the control diet and supplemented with rumen protected lysine (3g/ewe/day). The ewes were offered 1000 g/ewe/day of concentrate and wheat straw ad libitum in addition to grazing for 6 hr per day. Results revealed that ewes supplemented with P-LYS and F-LYS had a non-significant (P>0.05), increase in daily milk yield, fat content and yield, protein yield, fat corrected milk (FCM) and energy corrected milk (ECM). The serum urea concentration was reduced significantly (p<0.05) in the (P-LYS) and (F-LYF) compared to control group, while neither protected nor free lysine affecting (P>0.05) all blood parameters as well as rumen pH and protozoa numbers, while ammonia nitrogen (NH3-N) was numerically increased (P>0.05).

Accumulation of lead and cadmium in tissues of cyprinus carpio collected from cages of al-gharraf river /thi qar / iraq

Abstract: This study was aimed to investigate the lead and cadmium in water and in fish samples collected from three sites of Gharraf River at Thi Qar from September 2020 until April 2021. Results showed that (Pb) in river water ranged 0.156 - 4.306µg/l and the (Cd) 0.074 - 0.523 µg/l which recorded a significant differences among all sites as well as among all seasons. In addition the concentrations of Pb in some tissues of Cyprinus carpio ranged 0.069 - 4.98µg/g in muscles and kidney respectively, while Cd ranged 0.038 - 1.46 µg/g in muscles and kidney respectively. The study also showed a significant differences in Pb concentrations in fish tissues among all sites during seasons and recorded a significant differences in the summer compared with other season for Pb and Cd. A significant difference was also found in Pb and Cd concentrations between cages fish and the wild fishes for all seasons. The study proved that the water of the Al-Gharraf River is of low toxicity and less than the Iraqi and international standards, and the accumulation of Pb and Cd in the muscles of fish was less than the limits of the Federal Agency for Environmental Protection and the World Health Organization.

Effect of ethanolic extract of thyme and olive leave in quality characteristic of lamb patties during storage

Abstract: The aim of this experiment was to evaluate the effect of adding different levels of each of olive leaf extract (OLE) and thyme leaf extract (TLE) and their combination in some physicochemical, microbial, and sensory characteristic of lamb patties stored either at 4c° for 12 days or at -18c° for 120 days. Results revealed that there are a steady rise (p<0.01) in oxidative rancidity, microbial count and free fatty acid in control and treated samples with increasing time in both storage periods. Also, a significant (p<0.01) reduction in TBA, microbial count and free fatty acid was observed in samples treated with OLE, TLE and their combination. Moreover, it was found that addition of 1% OLE and 1% OLE +0.05%TLE are more effective against formation of TBA and microbial count, respectively. Sensory characteristics were highest in patties treated with 0.05% TLE and the lowest was noticed in samples treated with 1% OLE.

Microscopic examination of ovine babesiosis at baghdad city / iraq

Abstract: This study was conducted to detect the prevalence of Babesiosis in different areas at Baghdad city, by using microscopic examination ;180 sheep’s head blood samples were collected from each local breed (122 males and 58 females) with different age groups from 6 months to more than one year old, during the period extended from 1/October2019 to end of April 2020.Giemsa stained blood smears were done for detection Babesia spp. ; The overall rate of infection with Babesia spp. in sheep was 15.55% (28/180), significant differences P≤0.05 was recorded between male 19.67% ( 24/122) and female 6.89% ( 4/58 ), and sheep with equal or more than one year old registered higher rate of infection 18.18% (2/11) , also highest rate of infection recorded in April 45% (9/20) with highly significant differences P≤0.01 between months of study.
