2022
Mustafa Boğa | Barış Cem Avcı | Hatice Nur Kılıç
The rapid increase in the world population increases the need for plant and animal food. Agriculture and animal husbandry practices are becoming more common day by day to meet the need for food and to obtain more products. This situation increases the amount of waste per unit of animal products. Increased animal excrement is associated with greenhouse gas emissions, harms the environment and animal health. One of these greenhouse gases, methane, increases animal production and poses a significant threat to global warming. Feeding research, which optimizes rumens and animal productivity to reduce ruminant methane emissions, is one of the hottest topics today. The purpose of this study is to evaluate feed distribution in terms of chemical composition, methane production, net energy, and organic matter digestibility by collecting forage and concentrates from various ranches in Niğde. Therefore, to increase the productivity of livestock on small farms in Turkey, the ratio of feed ingredients was determined on a farm basis, and there were some comments on the lower and upper limits of the fattening rate. Gas and methane production of TMR samples was determined using in vitro gas production technology. Nutrient contents obtained from different livestock farms CP (9.58-14.72), CF (1.89- 2.30), CA (7.64-13.92), ADF (19.77-27.82) NDF (36.71-45.69) DM (90.48-91.79) content, methane (CH₄), OMS, NEL and ME values were also different (P

In this study, we aimed to determine the therapeutic value of local Yığılca honeys by examining their physicochemical characteristics, phenolic content, radical scavenging activity, and antimicrobial properties by underlining some overlooked parameters. Honey samples ware divided into two main groups as CH and FH based on melissopalynologycal analysis. Antimicrobial activity of collected honey samples were investigated on important hospital-acquired infections bacteria strains; MRSA (Methicillin-resistant Staphylococcus aureus), MSSA (Methicillin-sensitive Staphylococcus aureus), Escherichia coli, and Acinetobacter baumannii. Although CH’s antimicrobial activities were found slightly higher than the FH’s, there isn’t statistically significant differences between two type honeys. However, the antioxidant activity of CH was found significantly higher than FH. Surprisingly, a higher amount of isomaltose was determined in addition to the total phenolic content in CH compared to FH. There has been found positive correlation between isomaltose amount and zone diameters for MRSA and A. baumannii. We would like to draw attention to isomaltose for its health benefit structure since these parameters may be influence honey’s therapeutic value. We recommend that isomaltose and invertase enzyme should be included in to the honey codex standards suitably depending on the monofloral and multifloral honey’s specific structure, to sensitively standardize and control their quality and therapeutic value. Our data revealed a positive correlation between antioxidant and antimicrobial activity and total phenolic content and higher isomaltose amount.

2022
Eda Adal | Tuğba Aktar
Pomegranate (Punica granatum L.) is a fruit that grows in most tropical and subtropical regions. It has 52% aril, consisting of 78% juice which is used as; juice, molasses, jam, wine, and dried kernels. Potential health benefits increase the demand for the fruit as well as its products. Pomegranate seeds, which consist of approximately 10% of the whole fruit, are a by-product of the juice and juice using products containing nutraceutical functional components such as sterols and punicic acid. Pomegranate seed oil is considered a healthy alternative source of oils, and its production is a valorization process since it is the by-product that usually goes to waste. In the present study, pomegranate seeds were used for oil extraction using the cold solvent extraction method. Oil samples were then taken to the Schaal oven treatment in order to determine changes due to storage. Oil samples were tested for 14 days of total storage at their 1st,3rd, 7th, and 14th days for the oxidation tests, colour, fatty acid composition, and Fourier transform infrared spectra analysis. Data were tested for significance by using statistical analysis. The results indicated that oxidative stability of pomegranate seed oil was decreased by increasing storage time. The studied techniques used in this paper can be valuable processors to monitor the oxidative stability of oils with storage time and evaluate their acceptance on the market.

In this study, it was aimed to reveal the effect of temperature and humidity values provided by the semi-open and closed barns in the winter season on milk yield and components and the somatic cell count (SCC) level in milk in Anatolian buffaloes, and for this purpose, to compare both barn types and to reveal their suitability for buffalo breeding. In the study, temperature and humidity values were determined between December 2020 and March 2021 in two types of barns with similar feeding conditions in Bafra district, Samsun, and milk samples taken from buffaloes raised in these barns were analyzed. Temperature Humidity Index (THI) values were determined as 61,09±0,211 and 51.08±0.173 for the closed and semi-open barn type, respectively. In the study, in which the type of barn and therefore the temperature and humidity values provided in the barn environment did not affect the amount of milk yield, the milk fat ratio was determined as 8.89±0.227% and 8.16±0.176% for closed and semi-open barns, respectively. While other milk components were not affected by the barn conditions, the logSCC of milk was lower (4.54±0.071) in the closed barns when compared to the semi-open barns (4.73±0.044). Although no statistical difference was determined in the other milk parameters discussed, it was noted that there is an increasing tendency in the closed barns. It was observed that the changes in temperature and humidity values in both barn environments during the period caused nonlinear changes in milk composition. While indoor conditions were more effective on solids-non-fat (SNF), protein and lactose in the closed barn, the highest effect was on the fat ratio and logSCC in the semi-open barns. As a result, it can be said that both types of barns can be used in buffalo breeding since there is no significant difference in milk yield and other components, although there is a slight difference in milk fat ratio and logSCC level in closed and semi-open barns of Anatolian buffaloes in the climatic conditions of the region where the study was conducted.

Duried Alwazeer | Tunahan Engin
Molecular hydrogen is a colorless, odorless, tasteless, non-toxic, flammable, and diatomic gas. Molecular hydrogen is dissolved directly in water to be used in the form of hydrogen-rich water (HRW) to keep the freshness of fruits and vegetables. The shelf-life of the product was increased and the quality attributes were maintained when hydrogen was applied to some food products such as milk, tea, and fruit juices. Some grain products and greens grew rapidly and their antioxidant substance levels increased when they were supplied with hydrogen-rich water. Molecular hydrogen has shown an important application in food drying in recent years, was used especially in reducing atmosphere drying (RAD) technology. Few studies have been conducted on the use of molecular hydrogen in food products. Due to its various positive effects, the use of molecular hydrogen in the food industries using different techniques and processes could be encouraged by the presence review

There is an expanding interest in medicinal and aromatic plants as a natural alternative to synthetic drugs, especially to antimicrobial agents due to the growing problem of antibiotic resistance. In recent years, a lot of reports have been published on the antimicrobial activity of the plant extracts. This study was used Lavandula angustifolia L., Mentha piperita L., and Ribes nigrum L. as plant materials. This study aims to test the plant extracts against oral bacteria. Its purpose is to produce directly comparable, quantitative, antimicrobial data, and in addition to containing very little information of the different extracts against oral pathogens. Disc diffusion method was studied for antimicrobial activity tests. Also, minimum inhibitory concentration (MIC) values were determined in this study. Additionally, the extracts were tested against stable 2,2-diphenyl-1-picryl-hydrazyl-hydrate• (DPPH•) free radicals for non-enzymatic antioxidant activity. This study was used Trolox (6-hydroxy-2,5,7,8-tetra-methyl chroman-2-carboxylic acid) as standard. The extracts showed different inhibition zones against bacteria. The methanol extract of Lavandula showed the highest inhibition zone against the oral pathogen MBKK5. The positive control was penicillin (10 μg). The lowest MIC value was taken at 6500 μg /ml concentration of the plant extracts. The highest DPPH• radical scavenging activity was found in Ribes nigrum extract as 36%. As a result, plant extracts have antibacterial and antioxidant potential.

A total of 432, ISA Brown growing pullets were used to evaluate the effects of feeding diets containing Turmeric, Clove and Turmeric + Clove on growth performance and intestinal morphology. The birds were divided into 36 groups of 12 each weighed and allotted into experimental units. A total of nine experimental diets were formulated such that they contained 0, 1 and 2% turmeric, 0, 1 and 2% clove, and 0, 1 and 2% turmeric + clove combination on a 1:1 basis, respectively, in a 3 × 3 factorial arrangement (turmeric × clove × turmeric + clove: 0 × 1 × 2), replicated four times. The birds were weighed weekly to determine their body weight, weight gain, and feed conversion ratio. At the end of the experiment, 27 birds were sacrificed, and the duodenum, jejunum and ileum segments of the gastro intestinal tract were removed for gut histo-morphometry. Results showed that level of inclusion of feed additives significantly influenced feed intake (FI) and feed conversion ratio (FCR). Birds fed 1 and 2% inclusion of feed additive had reduced feed intake and lower FCR value when compared to higher FI and FCR values recorded in birds fed 0% inclusion of additives. Duodenal, jejunal and ilea morphology were significantly influenced by turmeric, clove, turmeric + clove, inclusion levels and treatment interaction. Birds fed diet containing turmeric + clove have significantly longer duodenal and jejunal villi as well as best duodenal and jejunal villus height: crypt depth ratio. It was concluded that up to 2% turmeric and turmeric + clove can be included in growing pullet’s diet for improved performance. Inclusion of turmeric, clove and turmeric + clove improved morphological changes in the duodenum, jejunum and ileum of birds which might influence nutrient absorption and thus, improved FCR.

Swarup Kumar Kundu | Shonkor Kumar Das
A myriad of health claims are being made in favor of the consumption of green tea due to its easy availability and greater popularity. On the contrary, certain health risks of excessive green tea consumption have begun to emerge. The aim of the present research was to observe the baleful effects of excessive green tea intake on hematological parameter and histoarchitecture of liver. A total of thirty (n=30) Swiss albino mice were taken and randomly divided into Control C, Treated T1, and Treated T2 groups. Each group consisted of ten (5 male+5 female) mice. The Control C group was fed with normal mice pellet and water (3ml/mice) orally but the treated T1 group was supplied mice pellet with 2ml/mice of green tea+1ml/mice of water orally as well as treated T2 group was given mice pellet and 3ml/mice of green tea orally two times in a day for 60 days. After the experimental tenure, mice of each group were sacrificed ethically and samples (Blood, liver and lungs) were collected for further hematological and histomorphological studies. Treated T2 group of mice were motionless (inactive and stagnant). Anatomopathologically, the liver surface became dark red in color with considerable hepatomegaly and mild hemorrhage also found on lung surface. Histologically, mild central vein congestion and severe venous congestion with dilation were found in the portal vein of the liver of the treated T2 group of mice. Hematologically, hemoglobin level significantly reduced in the treated T2 group of mice than the others. Within this experimental period, female mice of each group gave birth (15-18 pups) that were devoid of any abnormality. Therefore, it can be concluded that excessive green tea intake in a day might have baleful effects on hematological parameter (Hb concentration) and histoarchitechture of liver in Swiss albino mice.

The purpose of the study is to determine the effects of pre-starter feed prepared using different sugar sources on the performance, carcass parameters, internal organs and intestinal development, microbial load in broilers. In total, 360 newly hatched chicks divided into 4 treatment groups with 5 replicates. 18 chicks with similar live weights (9 male, 9 female) were used for each replicate. Control or pre-starter feeds (containing %14 saccharose, %14 dextrose, or %7 saccharose+ %7 dextrose) were used for the feeding of the groups. For the feeding of the control group, standard chick starter feed was used for the first 5 days; for the treatment groups, the pre-starter feeds prepared were used. For the rest of the trial period, all groups were subjected to standard feeding. A significant difference was observed among groups with regards to live weight gain and feed conversion rate during the first four weeks of the study; however, this effect disappeared over the last week. In addition, it was determined that any differences observed with regards to carcass parameters other than hot and cold carcass weights, internal organ development aside from proventriculus, intestinal development and microbial load were not significant. It was concluded that the pre-starter feed prepared with saccharose and/or dextrose did not show the expected effect
