2022
Harun Kutay | Hasan Rüştü Kutlu
In this study orange pulp, dried in hot air, was replaced at control, 7.5, 15 and 22.5% levels (DM basis) with ground corn in the concentrate feeds of dairy goats. Considering the milk yield, average live weight and age of the animals, a total of 24 animals were used in 4 groups with 6 animals in each. Goats with 1375±330 ml milk yield, 2.45±0.17 years of age and 55.40±0.91 kg body weight were chosen for the trial. The animals were housed in individual compartments of 2x2 m during the study. In 2 weeks of adaptation, 8 weeks data collection of the trial, feed and water were provided ad libitum. Orange pulp utilisation increased dry matter intake, did not change milk yield and feed conversion rates, and negatively affected the body weight changes. Somatic cell counts were found to be lower in the control group in the middle of the study. Blood glucose and cholesterol levels were reduced, NEFA and BHB increased due to the treatments.

The aim of the study was to describe the scenario of the present condition of production and management system of dairy buffalo at Haor areas of Sylhet in Bangladesh. Data were collected between February 2019 and January 2020. Sixty dairy farmers and thirty indigenous dairy buffaloes were selected for the study purpose. All respondent farmers were male and 65% were in between 40 to 50 years of age. Parity number had a significant relation in response of body weight. Quality analysis of milk showed that buffaloes which were reared at Haor areas have more fat content on an average 7.88% than buffaloes which were reared conventional dairy farm containing 7.34%. Price of buffalo’s milk and meat were varied with the seasonal changes, lower in winter season. All farmers fed the buffaloes only with green grass in winter. Four major diseases of buffaloes were found in Haor areas where the percentage of foot and mouth diseases was 15.59% followed by black quarter (11.01%), anthrax (7.34%) and hemorrhagic septicemia (6.42%). The buffaloes were not dewormed so parasitic infestations dramatically increased and easily transferred from one to another. The farmers had not enough knowledge about regular vaccination. But in contrast with profitability, total benefit cost ratio from buffalo rearing was 1:1.56 annually.

2022
Serhat Hepçin | Ali Gücükoğlu
This study aimed to investigate the presence of Aflatoxin M1 (AFM1) in raw buffalo milk and buffalo milk products such as cheese, yogurt, cream, and ice cream by ELISA technique. In the study, 175 samples were investigated, and it was determined that 146 (83.43%) of the samples had AFM1 concentrations below the LOD (limit of detection) value. In 29 samples (16.57%), the AFM1 concentration exceeded the LOD value, and in 7 (4%) of these, the AFM1 concentration was above the legal limits (50 ng/L). While AFM1 was not detected in raw buffalo milk samples, the presence of AFM1 in cheese, yogurt, cream, and ice cream samples was found to be 2.85%, 2.85%, 62.85%, and 14.3%, respectively. 2.85% of cheese samples and 17.1% of cream samples were found contaminated with AFM1 above the allowed legal limits (50 ng/L). As a result, it was determined that the potential for exposure to AFM1 by consuming buffalo cream was higher than the consumption of buffalo milk and other buffalo milk products. However, the detection of AFM1 above legal limits in buffalo milk products poses a serious risk to public health. Therefore, it is extremely necessary for public health to develop effective monitoring programs to control aflatoxin contamination in milk and new strategies to maintain inspections.

Marlon Numpaque | Tuba Şanlı | Elif Ayse Anli
The first introduction of human being with milk begins with human milk during infancy, continues with very commonly with cow’s milk and may be with other milk types during lifetime. Cow breeding and utilizing its milk in nutrition is widespread in the world. There are particular species common to their area such as donkey, camel, mare, yak and llama have an important share in milk production in the world. Donkey milk has higher serum protein and lower casein content being similar to human milk so regarded as a good and safer alternative for infants suffering from cow’s milk protein allergy. Mare milk is used as a therapeutic agent for the treatment of some metabolic and allergic illnesses. It is generally consumed as fermented product. Llama milk contains higher amounts of calcium and phosphorus than cow's milk. Camel milk has high vitamin and mineral content and has claimed to have medicinal proteins. Its casein micelle size is larger naturally and it has lower amount of κ-casein these cause difficulties in cheese making and affect curd quality. Reindeer milk is an energy dense food with its high fat and high protein content when compared to cow’s milk. Its high protein content could make it suitable for protein supplementation. Its low lactose content makes its consumption possible by lactose intolerance patients. Yak is richer in almost all main nutritional components when compared with cow’s milk. It can be used in cheese, butter making and dried milk products. The objective of this review was to represent the composition of different animal species’ milks; other than cow, buffalo, sheep and goat, their importance in nutrition and technological use.

Wajid Ali | Ethem Akyol | Ayhan Ceyhan | Sadia Dilawar | Asia Firdous | Muhammad Zia ul Qasim | Muhammad Moiez Ahmad
Globally, 16.9% of milk used by humans is taken from different species other than a cow. These species are sheep, horse, yak, ass, goat, camel and buffalo. The global camel (Camelus dromedarius) population is about 34 million head with sharing of almost 0.4% of world’s non-cattle milk. Within the last 20 years, the curiosity of camel farming is amassed remarkably in different countries of the world including the Netherland, Italy and USA for camel milk production. The camel is considered as a goal animal of the 21st century because it produces high quality milk under extreme temperature, deficiency of pasture and dearth of water. The average milk production of camel fluctuates from 4 to 30 lt with lactation length ranges from 9 to18 months having peak yield in second to the third month of lactation. Camel’s milk is used globally because of its salty taste, high vitamin C concentration and its medicinal properties. Nevertheless, it gives many valuable benefits such as treatment of autism, control diabetes and allergy, prevention from liver cirrhosis and replacer of cow milk to avoid an infant’s allergic reaction. The camel milk is a natural treatment of diabetes as it has a substantial result in a decrease of mean blood glucose and conserves necessary insulin doses. Camel milk constitutes of protein (2.5-4.5%), fat (2.9-5.5%), solid not fat (8.9 -14.3%), ash (0.35-0.95%), lactose (2.9-5.8%) and water (86.3-88.5%) as mean specific gravity is 1.03. Due to its distinct properties, the consumption of camel milk is increasing day by day and a number of industries are working to promote camel milk production and processing. Therefore, the tenacity of this review article is to explicate the beneficial uses and production of camel milk over the globe.

This study investigated the prevalence and concentration of antibiotic residues in twenty brands of milk. Determination and quantification of antibiotic residues was done using High Performance Liquid Chromatography. Aerobic plate count was carried out and the associated bacteria isolated. Identification of bacteria was done using standard microbiological methods. Molecular characterization and identification of bacterial isolates was done using 16S rRNA gene sequencing method. Antibiotic sensitivity was carried out on bacterial isolates using disc diffusion method. Plasmid profile of drug resistant isolates was done using alkaline analysis method. Comparison of means was done using Analysis of Variance. Antibiotic residues were detected in 10 (50%) of the 20 milk brands analyzed. The residual levels of tetracycline, oxytetracycline and chlortetracycline ranged between 5ng/kg and 1569ng/kg while none of the samples had doxycycline residues. The prevalence of tetracycline residues in evaporated milk brands and powdered milk samples were 100 and 23 % respectively. The aerobic plate counts ranged from 2.5 × 102 to 6.5 × 102 CFU∕mL for evaporated milk and 2.5 × 101 to 6.0 × 101 CFU∕mL for powdered milk. A total of ten bacterial species were isolated and identified. Susceptibility result showed that 95% of the isolates were sensitive to erythromycin, cefuroxime and gentamycin; 12.5% were resistant to tetracycline and ampicillin, 10% were resistant to ofloxacin and 7.5% to doxycycline and penicillin. Five of the bacterial isolates were resistant to more than one class of antibiotics. Resistant isolates subjected to plasmid profiling had detectable plasmids with estimated sizes between 120bp and 1000bp. The obtained results provide evidence that the presence of antibiotic residues in evaporated and powdered milk is an indication that the public is exposed to the harmful effects of the residues.

One-year investigation is carried out aimed at evaluating all incomes and costs with a specific focus on the impact of feeding factors in 12 Holstein dairy farms (in total 284 cows) in Kosovo. The cost of on-farm produced feeds; the price of purchased feeds and the price of milk were used for the analysis. All costs created during this period are duly registered and considered in the analysis. Economic analysis showed that prices of on-farm produced feed were much lower (30 €/ton for silages and for hay). Average daily feed cost was 2.33 €/cow/day, while milk income was only 4.9 €/d. Individual feed groups contributed to total milk cost as follows: silages with 0.04 €/kg, dry roughages with 0.02 €/kg, and concentrates with 0.10 €/kg, while all other factors taken 0.13 €/kg of milk price. This study showed that feed was the largest farm expense making 68% of total farm costs.

2016
Cemil Kürekci | Mustafa Yipel | Sevda Pehlivanlar Önen
The purpose of this study was to determine the antibacterial activity of plant derived compounds and essential oils of Corymbia citriodora against selected Gram negative and Gram positive foodborne pathogens in broth dilution assay. The combination of compounds (cineole, terpinen-4-ol and α-terpineol; CTαT) were further tested at three different concentrations (0.2, 0.4 and 0.8%) for the killing effect against E. coli O157:H7 and L. monocytogenes in milk including whole fat and skim fat. CTαT showed antimicrobial activity against all bacteria tested at minimum inhibition concentrations (MICs) from 0.125% to 1% in broth dilution assay. Linalool was also found to be antimicrobial at MICs between 0.25% and 2%, but not for Enterococcus casseliflavus. Further study carried out in milk showed that CTαT at concentrations of 0.4% and 0.8% significantly reduced the population of E. coli O157:H7 under detection limit in skim milk, whereas it was only effective at 0.8% in whole fat milk. CTαT, on the other hand, shown to be less active towards L. monocytogenes as only significant effect was observed at 0.8% in skim milk. Taken together results of the present study indicate that plant derived compounds could be valuable alternatives to inactivate foodborne pathogens in milk.

2024
Gürsel İşçi
The aim of this study was to explore the concentrations of PAEs (Phthalate esters) in milk in Türkiye. For this purpose, a methodology was developed to quantify eight different PAEs in milk samples using a combination of dispersive solid-phase extraction (dSPE) and Liquid Chromatography coupled with Tandem Mass Spectrometry (LC-MS/MS). Employing this methodology, the concentrations of PAEs were evaluated in 34 milk samples. Results indicated the presence of PAEs in the milk samples; however, all tested compounds remained within the specific migration limits established by the EU. Among the analyzed PAEs, BBP (Benzyl butyl phthalate) was not detected in any samples, while DMP (di-methyl phthalate) (ND-5.51 µg/L) and DBP (di-butyl phthalate) (ND-7.91 µg/L) exhibited the lowest concentrations. DEHP (bis(2-ethylhexyl)) was identified as the most prevalent plasticizer with a maximum concentration of 41.31 µg/L. In conclusion, this study successfully investigated PAE concentrations in Turkish milk samples using a developed methodology. The results indicated the presence of PAEs within EU-established limits, with DEHP being the predominant plasticizer. Further research and monitoring efforts are crucial to ensure ongoing safety in packaged milk products.
