Bu araştırma, süt sığırcılığı işletmelerinde yem tüketimi ve yem dönüşüm oranının belirlenmesi amacıyla yapılmıştır. Araştırmada kullanılan veriler Hatay ilinde 141 adet süt sığırcılığı işletmesinden derlenmiştir. İşletmelerde ortalama yem bitkileri üretim alanı 18,13 da olup, yem bitkileri ekim alanlarının bitkisel üretim deseni içindeki payı %31,07 olarak belirlenmiştir. İncelenen işletmelerde ortalama büyükbaş hayvan varlığı 11,02 baş, sağmal inek sayısı ise 4,87 baş olup, sağmal inek başına süt verim değeri 5.619 lt/baş, süt geliri ise 2.811 ABD$/baş olarak hesaplanmıştır. İşletmelerinde bir süt ineğinin bir laktasyon döneminde kaba yem tüketimi 3.139,67 kg, tüketilen yemin parasal değeri ise 371,61 ABD$, kesif yem ve kırma yem tüketimi 2.958,90 kg, tüketilen yemin parasal değeri ise 1.118,57 ABD$ olarak tespit edilmiştir. İncelenen işletmeler genelinde toplam masraf tutarı yaklaşık olarak 1,9 milyon ABD$ olarak gerçekleşmiştir. Toplam masraf içinde değişen masrafların payı %64,26 olup, sabit masrafların payı %35,74 olarak hesaplanmıştır. Yem masraflarının değişen masraflar içindeki payı ise %80,56’dır. Yapılan araştırma bir laktasyon döneminde sağmal ineklere verilen 1 kg kesif ve kırma yem tüketimine karşılık elde edilen süt miktarının 1,90 lt olduğunu ortaya koymuştur. İşletmeler ortalaması dikkate alındığında; 100 ABD$ yem tüketimi karşılığında süt sığırcılığının brüt üretim değeri için 236,02 ABD$, süt geliri için de 195,72 ABD$ olarak tespit edilmiştir. Yapılan araştırmada işletme büyüklük grupları arasında süt verimi ile kaba yem ve dane yem tüketim miktarı bakımından istatistiki yönden bir farklılıklar bulunduğu tespit edilmiştir. Yürütülen araştırma; incelenen işletmelerde hayvan başına daha yüksek süt verimi ve gelirine ulaşabilmek için özellikle işletmelerin yem ihtiyacını kendi işletmelerinden sağlamaları gerektiğini ortaya koymuştur.

Structures of agricultural holdings have been changing rapidly in rural areas. While smallholders have been decreasing in number, the number of large farms has been increasing. Youth has been rapidly moving away from agriculture. The agricultural sector has faced an aging problem. The involvement of youth and smallholders in agricultural production is extremely important for food supply security. This study aimed to observe the structural change of agricultural holdings based on the Farmer Registration System (FRS) data. The answers to the following questions were sought. Has the numerical and proportional distribution of enterprises changed according to their size? Has youth been moving away from agriculture? FRS records between 2003-2020 were used in the study. Agricultural holdings were grouped according to their size and the age of farmers. Results were summarized in tables and graphics. There was a decrease in the number and rate of farmers under the age of 40, and a proportional increase in the number of farmers over 65. While the number of agricultural holdings larger than 500 increased 2.5 times, the number and rate of small farms decreased. Migration from the districts and villages in the study area has been observed at rates ranging from 22% to 59% in 20 years. Special measures should be taken for youth and small farms to survive in the agricultural sector. Tools such as tax exemption and social security support can be used. Integrated rural development approaches, including basic services such as education and health, are indispensable for the population to be permanent in rural areas.

This study was aimed to determine the effect of hatching system (house and machine) and egg weight (heavy and light) on growth performance and meat quality traits in geese. The study was carried out for 12 weeks with a total of 220 Turkish native geese. The geese were individually weighed every 2 weeks during the study, on these same weeks feed conversion ratio (FCR) was measured. Hot and cold dressed, blood, head, foot, edible internal organs (heart, liver, gizzard), abdominal fat, neck, back, breast, thigh and wing percentages were determined. Also cooking loss, drip loss, color and pH were determined as meat quality traits. There was no significant difference between the egg weight groups in terms of BW. However, the geese produced in the house hatching system showed more BW from 6 to 12 weeks of age onwards compared to the machine system. There was no significant difference between the groups in terms of FCR by 8 weeks. Both 10 and 12 weeks FCR were determined as the worst house heavy, while the best house light groups. Hot and cold carcass percentages in geese hatched from heavy were higher rates than light eggs. The percentage of wings differed significantly among geese produced from different egg weight groups. Breast meat cooking loss was found higher rates in heavy eggs than light eggs, while thigh meat cooking loss was found higher rates in the house than machine system. The results of this study show that geese hatched in the house system had more BW at the slaughter age compared to machine system geese. In addition, geese produced from heavy eggs showed a higher hot and cold dressed percentages than geese produced from light eggs.

E. coli and Salmonella spp. are responsible for causing colibacillosis and salmonellosis in chickens respectively. This research work was undertaken to study the prevalence of colibacillosis and salmonellosis in commercial chickens of Chattogram, and to know the antibiogram profiles of the isolated bacteria. A well-structured questionnaire was used to know the prevalence of colibacillosis and salmonellosis. Previously collected liver and heart samples through postmortem of a total of 100 dead and sick chickens were used. MacConkey agar, EMB agar, and XLD agar were used to isolate, and identify E. coli and Salmonella spp. Finally, Gram’s staining and different biochemical tests were performed to identify these two bacterial isolates. 14 different commercially available antimicrobial discs like ciprofloxacin, enrofloxacin, streptomycin, colistin sulphate, neomycin, cefoxitin, amoxycillin, tetracycline, gentamicin, norfloxacin, azithromycin, doxycycline, cloxacillin, and erythromycin were used. Data were analyzed with p-value by using Graph Pad Software. 48 samples were recorded as positive for E. coli and 5 for Salmonella spp. The prevalence of E. coli and Salmonella spp. were varied depending on different parameters like age, bird rearing system, farm size, source of water, source of food, medication and vaccination. Form antibiogram study it was revealed that E. coli was highly sensitive to colistin sulphate and ciprofloxacin; intermediate to gentamicin followed by cefoxitin and resistant to other 10 antimicrobials. In case of Salmonella spp., it was recorded as sensitive to colistin sulphate, and cefoxitin; intermediate to ciprofloxacin, and resistant to other 11 antimicrobials. The findings of this research work would certainly help the poultry farmers to select proper antibiotics against colibacillosis and salmonellosis in chickens of Bangladesh and to overcome the multi-drug resistant problem of the bacteria.

The main source of seed filling results from the photosynthesis of the green tissue closest to the seed sinks in the capitula. To evaluate the role of different leaf strata and capitula in seed yield and its components of Safflower genotypes, a field study was performed as a factorial experiment based on RCBD in 3 replicates in East Azarbaijan Agricultural and Natural Resources Research and Education Center in 2008. The used factors in this experiment were: two Safflower genotypes including (Mahalli Esfahan and Goldasht) and defoliation in five levels: defoliation of plants in lower 1/3, middle 1/3, upper 1/3 of the stem, capitulum covered with aluminum paper and control (without defoliation). The results showed that defoliation did not affect plant height and number of pods. But, there was a highly significant difference between strata in terms of number of seeds per pod, number of seeds per plant, 1000 seeds weight, oil percentage and oil yield. The interaction of genotype×strata treatments in seeds yield and harvest index was significant. Among the defoliation treatment levels in both genotypes, the highest decrease in the seed yield compared to the control were observed in the upper 1/3 defoliation levels, whereas the lowest decrease was observed in the lower 1/3 defoliation level. The rate of seed yield reduction in Mahalli Esfahan was higher than Goldasht. The change in Goldasht seed yield was mostly due to changes in the number of seeds per plant and the number of seeds in the head. In addition, net photosynthesis, strata leaf area, and photosynthesis contribution of the upper strata compared to the lower ones were higher, and removal of the upper strata had the highest effect on seed yield through the reduction in the total photosynthesis of the whole plant. Also, covering the capitulum caused a significant decrease in the seed yield. So, head photosynthesis has a major contribution to Safflower seed yield.

Labneh is one of the most consumed dairy products in the Lebanese community, on breakfast, as a snack or on dinner, plane or mixed with herbs. Its various health benefits plus its acceptability among people makes it an important part of the Lebanese diet. In both its synthetic and homemade forms, several additives are usually incorporated to enhance its flavor and offer a variety of tastes. The problem with Labneh is its short shelf life, as well as its sensitive sensory profile. That is why most industries mix chemical additives with Labneh to prolong its shelf life and conserve its taste. The aim of this research is to preserve Labneh naturally by adding Moringa Oleifera dried leaves to extend its shelf life and inhibit rapid spoilage. Working on a natural preservation of Labneh instead of chemical preservation will be assessed by the survey’s results and prepare for studying the overall acceptability of the product by making a sensory analysis. The results of the questionnaire showed that the Lebanese community which is not totally aware of Moringa Oleifera benefits and availability, is willing to try fortified Labneh with Moringa as a new product with extended shelf life and more health benefits. The results of the sensory analysis showed that the sensory attributes of the samples with Moringa after 21 days of storage, where not significantly different than normal plane Labneh, which indicate that adding Moringa did not affect the sensory attributes of Labneh giving it more acceptability to consumers.

High morbidity and mortality rate associated with pneumococcal infection globally is of major concern most especially among infant. This burden is equally worsened by multidrug resistance strains due to indiscriminate consumption of antibiotics. Hence, need for constant search for cheap and effective bioactive compounds as alternative antimicrobials for the treatment of pneumococcal infection. Bioactive compound profiling and in-vitro antibacterial activity of ginger methanol extract against two predominant pneumococcal agents; Streptococcus pneumonia and Haemophilus influenza were investigated. Gas Chromatography Mass Spectroscopy (GC-MS) was used for the identification and quantification of bioactive compounds in the ginger methanol extract. The antibacterial activity and Minimum Inhibitory Concentration (MIC) of the extract was determined using Agar well diffusion. Twenty-seven (27) matched bioactive compounds were detected in the sample. Zingerone (17.70%), α-zingiberene (13.30%), (6)-shogaol (10.84%), α-Farnesene (6.26%), β-Funebrene (5.61%), 6-gingerol (5.18%), α-curcumene (4.15%) were the major compounds present. All other identified compounds had less than 4% composition by peak area each. The antibacterial activity of the ginger crude methanol extract against S. pneumonia and H. influenza were 2.33 mm and 9.33 mm. MIC of the extract against the isolates was 10%. In conclusion ginger crude methanol extract contain an array of bioactive compounds and the extract exhibited antibacterial activity against predominant pneumococcal agents. Ginger extract can be harnessed for the production of new antimicrobials to combat pneumococcal infection.

In this study, the effects of UV B (50 µW/cm2) radiation at 306 nm on oil-in-water emulsions (O/W) using canola oil, soybean oil and linoleic acid were investigated. The oxidation rates of emulsions incubated at pH 7.0 and 37°C in the presence and absence of Cu (II) ions were determined by using iron (III) thiocyanate and thiobarbituric acid methods for the determination of primary and secondary products, respectively. The UV B-induced oxidation rates followed the order LA / Cu (II) > LA > Canola Oil / Cu (II) > Canola Oil > Soybean Oil / Cu (II) > Soybean Oil for both crops. Simultaneously, structural studies were performed using gas chromatography mass spectrometry (GC-MS). It was found that 18-carbon polyunsaturated fatty acid (PUFA) and monounsaturated fatty acid (MUFA) contents have an important role in canola and soybean oil oxidation. The unsaturated fatty acid contents of small carbon numbers increased for each emulsion sample, while the oxidation of fatty acid changes did not follow a regular order.

The aim of this study is to contribute to the valorization of the cocoa bean varieties “Mercedes” and “Forastero” grown in Côte d’Ivoire. A comparative characterisation of phenolic compounds and minerals in the beans of the “Mercedes” and “Forastero” varieties from two major cocoa production areas of Côte d’Ivoire were determined. The phenolic compounds of cocoa beans were determined by high performance liquid chromatography (HPLC) and the minerals by atomic absorption spectrophotometer. The study showed that a significant difference at the 5% level was observed in the averages of minerals, cinnamic acid, protocatechic acid, quercetin, coumaric acid, rutin, ellagic acid, veratric acid, epicatechin, ferulic acid and naringenin. On the other hand, no significant difference at the 5% level was observed in the averages of arbutin, catechin, vanillic acid and caffeic acid in the bean kernels analysed in the Divo and Abengourou regions. The proportion of cinnamic acid is (6.18±0.63 mg/100g “Mercedes” Divo), that of ellagic acid is (18.48±0.44 mg/100g “Mercedes” Divo) and that of naringenin is (5.95±0.35 mg/100g “Mercedes” Divo). The amount of potassium is (7569.97±1.51 mg/kg “Forastero” of Abengourou) and that of iron is (179.9 ± 0.70 mg/Kg “Forastero” of Divo). The phenolic compounds and minerals in the cocoa bean samples analysed are highly correlated and rich in antioxidants. They would be beneficial for many biological functions. They can be recommended in pharmacology and cosmetics to fight against oxidative stress and cardiovascular diseases.
