2016
Sim Kheng Yuen | Mohammad Raisul Alam
The aim of the study was to investigate the raw milk hygiene and quality among the small holder dairy farmers in Tawau area. A total of 216 samples were collected from the respective dairy farmers and milk collecting centre located at Mile 15, Tawau. Preliminary results indicated that the quality of the raw milks obtained at farm level contained were inferior with high bacteria load (> than 107 CFU/ml). The total coliform (2.9-3.8 CFU/mL) and Staphylococcus count (2.3-3.6 CFU/mL) were relatively high in certain samples. However, none of the food borne pathogens was found. Trace back study revealed that the causes of contamination were attributed by poor hygienic handling among the dairy farmers and insufficient for immediate chilling of raw milk. A significant reduction in bacteria load was observed if the raw milk chilled immediately at farm. The implementation of modified pre-milking sanitizing practices improved the microbiology quality of the raw milks obtained from respective dairy farms. Future study will focus more on the effect of prolong storage towards the microbiological quality of raw milk.

The aim of this study was to investigated the effects of the egg shape index on egg quality characteristics in Guinea fowl. For this, the eggs were classified in terms of egg shape index, as ≤ 75, < 76 -77 > and ≥ 78. A total of 100 Guinea fowl eggs were evaluated to determine the egg quality traits ( egg weight, eggshell thickness, eggshell surface area, eggshell weight per unit surface area, eggshell ratio, albumen index, albumen ratio, yolk index, yolk ratio, yolk/albumen ratio, haugh unit and egg volume). In this study, eggshell thickness, eggshell weight per unit surface area, eggshell ratio, albumen index, albumen ratio, yolk index, yolk ratio, yolk/albumen ratio and haugh unit were not significantly affected by egg shape index groups. Whereas egg weight, eggshell surface area and egg volume were significantly affected by egg shape index groups. At the same time, there were found significant relationship between the egg shape index and egg quality traits. Egg shape index was found to be an important factor affecting the egg quality characteristics.

Mostrar más [+] Menos [-]Trace Minerals in Poultry Nutrition and the Efficiency of Chelating Forms
2016
Kasım Özek
The efficiency of chelated forms of trace minerals in poultry nutrition and the trace minerals requirements of poultry were discussed in this review. Trace minerals are essential for all farm animals, and these minerals, individually or together with other mineral, take part in many events such as metabolic activities, development and repair of different tissues, growth, immune and reproductive systems. In the last years, lots of studies related to different organic forms of trace minerals on the effects of broiler and laying hens were carried out. The results of these studies have showed that organic trace minerals added to poultry diets at lower levels than inorganic trace minerals are more efficient than inorganic trace minerals and they provide some advantages in poultry nutrition. One of the most important advantages is the reduction of mineral amount excreted in faces. In addition, the results of researches conducted especially in the last few years have shown that the chelated forms of trace minerals strengthen the poultry immune system, and increase the use of other nutrients. However, there are inconsistent between the effects of different forms of trace minerals used in poultry diets on the performance.
Mostrar más [+] Menos [-]Study on Prevalence of Mycoflora in Wheat Seeds
2016
Pratishtha Adhikari | Gopal Bahadur Khatri-Chhetri | Sundar Man Shrestha | Santosh Marahatta
Forty seed sample of wheat (Triticum aestivum) were collected from four locations viz. Chitwan, Kaski, Banke and Lalitpur and tested by blotter method at laboratory during 2013 for determining fungal pathogens associated with wheat seeds in Nepal. Eighteen species representing thirteen genera of fungi were recovered from the seed. Alternaria alternata and Bipolaris sorokiniana were predominant in all the varieties/genotypes from all the locations, where B. sorokiniana was strongly pathogenic in wheat crop. Percentage frequency and type of fungi detected varied with variety and locations. Bipolaris sorokiniana was highest (64.40%) in Banke than remaining three locations. Seeds of Chitwan had lowest percentage (5.50%) of seed infection as compared to other locations. Relative abundance of Alternaria alternata (55.10%) was highest as it was the most prevalent component of seed borne mycoflora, followed by Bipolaris sorokiniana (34.69%) and Cladosporium herbarum (7.19%). Differences in quantity of precipitation and relative humidity might be the possible reason for variation in frequency and type of fungi detected in wheat seeds of four locations.

The aim of this study is to reveal allelopathic effects and antioxidant activities of methanolic extract of Ganoderma lucidum in Zorkun plateau (Osmaniye). It was determined that methanolic extract of G. lucidum has significantly phytotoxic effect by increasing the doses (1, 2, 4, 8 mg/mL) on Hordeum vulgare and Triticum aestivum. Total phenol and flavonoid amounts of G. lucidum were 114.55 mg/kg and 8.95 mg/kg, respectively. 2,2-diphenyl-1-picrylhydrazyl (DPPH), scavenging activity (60%, 91% and 92%), reducing power (0.83, 1.43 and 2.23 Abs), and nitric oxide (NO) scavenging activity (48%, 55% and 70%) of this mushroom at the different concentrations (1.25, 2.5 and 5 mg/mL) were determined, respectively. However, H2O2 scavenging activity of the different concentrations (0.0156-0.125 mg/mL) was found as 18%, 56%, 60% and 86%, respectively. Based on these findings, it can suggest that G. lucidum methanolic extract has significantly phytotoxic effect and antioxidant activity. The present study is the first report on the phytotoxic effects and antioxidant activities of G. lucidum which consumed and collected from Amanos Mountains.

The aim of this study is to evaluate the quality characteristics of physical, chemical and microbiological of some fruit nectar samples produced from some local and imported companies and sold in the city of Tripoli, and to determine their conformity with Libyan specification standards. In this study, 40 samples of different fruit nectars (grape, pineapple, guava, orange, apple, and mixed fruits) were collected from different local supermarket, five imported companies and 4 domestic which were available at the time of study. The Samples were classified based on their type of fruit nectars and also marked as (A, B, C, D) and (E, F, L, M, N) for different domestic or imported and imported companies respectively. The results showed that all the samples were free from artificial colours added. Local and imported samples were conform with the Libyan specification standards (990-2014) for fruit nectars. Five local and four imported samples were unconfirmed with the standards. In terms of acidity, some local and imported samples were conform to the Libyan specification standards, except one local sample and 5 imported samples. However, 35.3% of local samples and 43.5% of the imported samples unconfirmed to the Libyan standard specifications. Microbiological results showed that all local and imported samples were free from total bacterial count, yeasts and molds and coliform bacteria. Heavy metals (cadmium, lead, arsenic, copper, zinc, iron) of local and imported samples were conform to the Libyan specification standard, except 3 samples of imported products were had higher arsenic concentration. Based on the results of this study which indicated the importance of quality control programs for such products not only during production but also during storage and sales due to possibility of contamination and spoilage.

Hacer Tüfekci | Mustafa Olfaz
In this study was aimed to crossbred male kids of the Hair goat and Saanen x Hair kids (G1) body condition score and compare their body size intensive, semi-intensive and extensive conditions. In the research, 30 Hair goat and 30 Saanen x Hair goat (G1) crossbred single male kids was used. When the research findings were evaluated, in terms of body condition scores of 30, 60 and 90th days high values in the semi-intensive were detected in fattening Saanen x Hair goat (G1) crossbred kids. However, at the end of fattening in semi-intensive fattening group of Hair goat it is determined that the value of the highest condition score. This situation is thought to be caused by more growth of environment and width measurements in Hair goat kids in the later stages of fattening according to the Saanen x Hair goats (G1) crossbred. In study in terms of body length during whole fattening, in terms of the height at the withers data obtained from the 60th and 90th day was found statistically significant. At the end of the fattening in semi-intensive fattening group of Saanen x Hair goat (G1) crossbred it was observed to have higher body length and height at the withers value of crossbred kids. When chest width measurements between paddles in kids were examined, in all periods seems to be an increase in Hair goat kids than the Saanen x Hair goat (G1) crossbred kids. At the end of fattening in terms of height rump Hair goats has shown higher values than Saanen x Hair goat (G1) crossbred kids but the highest values of the semi-intensive group has shown. As a result, semi-intensive feeding group of kids of body condition score and body size was higher than intensive and extensive fattening group kids, in terms of length and height measurements Saanen x Hair goat (G1) crossbred kids in terms of width and environmental measures has shown higher values than Hair goat kids.

Rehab Eltejani Abdelkarim | Mohammed Alhadi Ebrahiem
This study was designed in order to assess and evaluate the effect of hot iron branding on cattle hide quality. 62 shapes of hot iron branding were detected and classified. Branding damage was evaluated depending on: purpose of application, location in the animal body, branding area, tribe which applied and hide degree. The results showed that, Baggara tribes branding were causing the greater damage on cattle hides; where 71.4% of its brands placed in the abdominal and animal back area (middle of the hide); in proportion to Misseriya Zuraq tribes (68.4%). According to the location of branding, the less tribe that causing damages to the cattle hides were Darfur tribes (14.3%). In terms of branding area Darfur tribes were causing the most branding damages where 42.8% of its brands on cattle hides were between 20-30cm, followed by Baggara tribes where 57.1% of its brands were between 10-20cm then Misseriya Zuraq tribes by 52.6%, and finally North Kordofan tribes of 37.5%. grading of cattle hides depending on the presence of the brand marks the study revealed that, Misseriya Zuraq tribe's brands were obtained the highest percentage (89.4%) of the rejected hides (Scarto= 4 and 5 grades), when compared with North Kordofan tribes (87.5%). For commercial reason brand's were mostly done in the area of 5-10cm but, their effect on cattle hide quality was greater, where 81% of the hides were classified as Scarto.
