Use of Moringa Oleifera in Poultry and Ruminant Nutrition Full text
2015
Tugay Ayasan
The poultry industry in the developing countries is facing some challenges, one of which is an increase in the cost of feed because of high prices of protein and energy sources. Moringa oleifera is a rich source of protein and crude fiber content. The crude protein (CP) content of Moringa ranges from 7.12 to 39.17%. Negligible content of tannins and other anti-nutritive compounds and offers an alternative source of protein to ruminants and non-ruminants. Although rich in nutrients such as protein and minerals, Moringa oleifera is one of those plants that have not been studied for many years. In addition, they are also faced with the problem of the development of antibiotic resistant pathogens due to unwise and excessive use of antibiotics. In this paper, feeding studies made on the Moringa oleifera used in nutrition of poultry and ruminant species have been reviewed.

Salmonella species are important foodborne pathogens that have been implicated in a number of foodborne outbreaks. A total of 240 beef and its related samples obtained from the Techiman Municipality of Ghana were screened using the conventional method in the Food and Drug Administration-Bacteriological Analytical Manual (FDA-BAM)-USA. The overall prevalence of Salmonella species was 57.08%. The prevalence of Salmonella species ranged from 33.30% to 75.00% in the meat and its related samples (table, knife and apron), and 6.30% to 93.80% at the various meat sale points (locations where meat is sold). Prevalence of Salmonella species was significantly higher in meat (75.00%), table (60.00%) and knife (60.00%), than apron (33.33%). The most contaminated meat sale point was Kenten and Main markets (93.75%) and the least contaminated sale point was Sansema junction (6.25%). All the Salmonella species were susceptible to ciprofloxacin but resistant to vancomycin. Intermediate resistances occur for all the antibiotics except ciprofloxacin and vancomycin. The Salmonella species also exhibited 23 antibiotic resistant patterns with the pattern EVa (erythromycin and vancomycin) being the commonest (exhibited by nine different isolates). Multiple antibiotic index (MAR index) ranged from 0.11 to 0.67. This study revealed that beef and its related samples in Techiman markets are contaminated with Salmonella.

Erdal Yaylak | Hikmet Orhan | Alim Daşkaya
The present study was conducted to determine some environmental factors affecting birth weight, weaning weight and daily live weight gain of Holstein calves of a livestock facility in Izmir, Turkey. The data on 2091 calves born between the years 2005-2010 were used to assess the relevant parameters. Effects of calving year, calving month, calf gender and the interaction between calving year and calving month on calves’ birth weights were highly significant. The overall mean of birth weights was 39.6±0.15 kg. In addition, effects of calving year, calving month, gender, birth weight, weaning age, calving year x calving month, calving year x gender and calving year x calving month x gender interactions on weaning weight (WW) and daily live weight gain (DLWG) were highly significant. The overall means of WW and DLWG were respectively found to be 79.7±0.20 kg and 525±2.5 g. A one kilogram increase in birth weight resulted in an increase of 0.89 kg in weaning weight and a decrease of 1.26 g in daily live weight gain. Prenatal temperature-humidity index (THI) affected birth weight of calves (R2=0.67). Increasing THI from 50 to 80 resulted in 3.8 kg decrease in birth weight.

Meltem Serdaroğlu | Burcu Öztürk | Ayşe Kara
Emulsions take place partially or completely in the structures of many natural and processed foods or some foods are already emulsified in certain stages of production. In general “emulsion” is described as a structure created through the dispersion of one of two immiscible liquids within the other one in form of little droplets. Many terms are available to describe different emulsion types and it is very important to define and clarify these terms like “macro emulsion”, “nanoemulsion” and “multiple emulsion”. Nanoemulsions become increasingly important in food industry as an innovative approach in carrying functional agents. Application potential of multiple emulsions (W/O/W) is also stated to be very high in food industry. The two main strategic purposes of utilization of multiple emulsions in food applications are to encapsulate various aromas, bioactive compounds or sensitive food compounds and to allow the production of the low-fat products. This review provides an overview to the general terms of emulsion types, the role of various emulsifying agents, and the application potential of emulsions in food industry.

Gamal El Afandi | Mohamed Abdrabbo
Precise estimation of the reference evapotranspiration is very important and vital in different fields such as agriculture, hydrology and meteorology. The aim of the current study was to evaluate the performance of different reference evapotranspiration methods compared to Class-A pan or E-pan over different agro-climatic regions in Egypt. In this study, Egypt has divided into several agro-climatic regions according to the average air temperature and the reference evapotranspiration from Class-A pan. These were Nile Delta in the north, middle and Upper Egypt. Four reference evapotranspiration (ETo) methods namely; Blaney-Criddle, Hargreaves, Thornthwaite and FAO-56 Penman-Monteith (PM) have been evaluated in this study. The results revealed that, there were statistically no significance between E-Pan and PM at P-value less than 0.05, while the other equations had significant differences. The Hargreaves equation reported the highest ETo value at all regions while Thornthwaite was the lowest one. The difference percentage ratios between FAO-56 Penman-Monteith, Blaney-Criddle, Thornthwaite and Hargreaves and E-Pan were 3.7, -13.3, -24.8 and 10.7 respectively. Hence, FAO-56 Penman-Monteith method has proved its capability in estimation of reference evapotranspiration over different agro-climatic regions in Egypt. Therefore, it could be used over any region in Egypt especially those have no reference evapotranspiration instruments.This study is a regional research, similar studies has been made for different regions by many researchers. Therefore, the determined results in this study can be used for regions with similar climatic conditions.

The study was designed to determine the consumers’ attitude and behaviors towards poultry meat consumption and to analyze the factors affecting on their meat consumption. The data obtained from 385 households consuming the poultry meat and residing in Erzurum province. As the data set based on Principal Component Analysis to determine the main factors affecting the consumption according to the poultry meat attributes and K-means Cluster Analysis to constitute the homogenous segments related to their consumption frequencies were used. According to the results of the study; the heavy users (C1) consuming the poultry meat consumption constituted the desirous and sensitive consumer segments based on both product image and price-sensitive contributing to the regional and rural development under the augmented product mix registered with the origin of the region. On the other hand, while the medium users (C2) focused on the concept forming their diets under the core benefit and the disease risk of the poultry meat by considering the sensorial and main quality attributes, light users (C3) also tried to maximize their total utility through products with generic brand. Therefore, it could introduce the augmented product mix under the product strategies with local brand with the origin of region for C1, the private brand strategies meting ISO 9001 and HACCP standards for C2, and the generic branded product with the origin of region in accordance with the product image for C3. In this way, it could be contributed to the rural regional developments, and thus could be increased the welfare levels of the people living in the rural areas by providing both the producer and consumer satisfactions.

This study was carried out to determine and compare the proximate composition and length weight relationship of C. gariepinus from two culture systems (earthen and concrete ponds). The fish samples were collected from three fish farms with same cultural condition in different areas of Obio-akpor Local Government Area of Rivers State, Nigeria. Result on the length- weight relationship revealed that C.gariepinus reared in concrete tank had a total length of 15.50- 49.00cm with a mean of 32.71cm and weight of 150-625g, while total length of C. gariepinus reared in the earthen pond ranged from 19.90-58.0cm with a mean of 39.8cm and weight of 195-825g. The T- test shows that the total length of earthen pond were significantly higher than the concrete tank and the weight in the earthen pond was significantly higher than the concrete tank. Parameters of proximate composition analysed were moisture, protein, lipid, carbohydrate, ash and fiber from the fish flesh. Protein content showed a significantly higher in the earthen ponds than the concrete tanks. Ash contents varied from 1.5±1.66-7.4±0.67% in the concrete tanks and were significantly higher than the earthen ponds which ranged from 3.1±0.94-4.5±2.11%. Lipid was significantly higher in earthen ponds than concrete tanks. Generally, the two culture systems have a significant influence on length–weight relationship and nutritional value of C. gariepinus. However, C. gariepinus reared in concrete tank had a heavier body weight than earthen pond and also C. gariepinus reared in earthen pond had highest nutritive values than the concrete tank.

Gelişen ve durmaksızın ilerleyen teknoloji, çevre kirliliği, radyasyon, kontamine sular, tarım ilaçları, ağır metaller ve canlı hücrelerdeki oksijen metabolizması gibi birçok etken insan vücudunda kaçınılmaz olarak serbest radikallerin oluşumuna neden olmaktadırlar. Serbest radikaller, oksijenin oldukça reaktif formları olup, vücut hücrelerini tahrip etmektedir. Bu da kalp damar hastalıkları, kanser, katarakt, diyabet, karaciğer tahribatı ve diğer pek çok hastalığa davetiye çıkarmaktadır. Bu hastalıklara çözüm getirmek öncelikle serbest radikallerin olumsuz etkilerini bertaraf etmek ve hastalıkların oluşumunu engellemekle gerçekleşebilir. İnsan vücudunda bunu engelleyebilecek antioksidan savunma sistemi mevcut olsa da karşılaşılan çevresel etmenler bu savunma direncini düşürmekte ve çoğu kez yetersiz bırakmaktadır. Zayıflayan antioksidan savunma sistemlerimizi doğal ve dengeli beslenerek güçlendirebiliriz. Bu makalede serbest radikallerin neden olduğu hastalıklara karşı direnç gösteren en önemli endojen ve ekzojen doğal antioksidanların sınıflandırılması ve insan sağlığına etkileri incelenmiştir.

Seyit Hayran | Aykut Gül
This study aims to determine and analyse farmers’ risk perceptions and risk management strategies in dairy farming. Data were obtained in 2014 (December) and 2015 (February and March) from face-to-face interviews with 96 dairy farmers in Yüregir and Saricam district of Adana province of Turkey. Factor analysis was used in data reduction to identify a small number of factors related to risk sources and risk strategies in this study. Then, multiple regression model was used to evaluate the influence of socio-economic characteristics and communication behaviour on the farmers’ risk perceptions and risk management strategies using factor loadings. The results of this study show that the most important risk source that the farmers' perceive is variability in feed prices and risk management strategy that the farmers' perceive is take precautions to prevent disease. The results of factor analysis show that the risk scale consists of 8 factors explaining 70.24% of total variance. The internal consistency coefficient Cronbach Alfa of the scale is 0.808 and KMO is 0.732. The risk management scale consists of 6 factors explaining 67.78% of total variance. The internal consistency coefficient Cronbach Alfa of the scale is 0.775 and KMO is 0.746. According to the results, perceptions were farmer-specific, a number of socio-economic variables and communication behaviour are found to be related to risk and risk management. To improve risk management strategies is useful for farmers as well and might help them to avoid many risks and reduce losses.
