The study was conducted to investigate the effects of ensiled guinea grass (GG)- cassava peel (CSP) enriched with soybean cheese waste (SBCW) in varying proportions into 4 treatments: T1 (GG100%), T2 (GG80% + CSP10% + SBCW10%), T3 (GG60% + CSP30% + SBCW10%) and T4 (GG40% + CSP50% + SBCW10%) on West African Dwarf goats. Twenty WAd goats were allocated into four silages of five growing WAd goats each. Daily feed intake and weekly weight gain were measured for twelve weeks of the experiment. Digestibility study was carried out using Three animals per treatment for faeces and urine collection. Blood samples were collected via jugular vein for blood profile analysis using standard measures in a completely randomized design. The Crude protein (CP) concentrations of silage increased with the increasing level of cassava peels. Crude fiber levels of the silages also followed the same trend. The group of animals fed T4 had highest feed intake among the treatment groups. Daily weight gain of goats in T4 was better enhanced than other treatments. The apparent digestibility was significantly different (P˂0.05) among the treatment groups. There were diet effects on the parameters measured for rumen liquor of the animals fed silages. The treatments had no effects on the haematology and total protein of goats fed diets. It is therefore indicated that agro-industrial by-products ensiled with guinea grass are potential means of feed sustainability during the dry season period for goats in Nigeria without any deleterious effects on goats’ health and performance.

Poultry meat quality is controlled by muscle fiber properties associated with body weight gain in the immediate pre- or post-hatch period. This study aimed to determine the effect of administration of branched-chain amino acids blend (BCAAb, 3 L-leucine:1 L-isoleucine:2 L-valine) in the pre- or post-hatch period on the growth performance and fiber characteristics of the Pectoralis major (PM) muscle in turkey poults subjected to early or delayed feeding. Newly hatched poults from eggs injected in ovo with BCAAb or received no injection were used in a 21-d study. Poults (n=192) produced without injection of BCAAb received a starter diet supplemented (BCAA) or not (C) with the BCAAb (2 g/kg) immediately or with a delay of 48 h (48BCAA and 48C) after hatching. Poults (n=36) produced with (IOBCAA) in ovo injection of BCAAb (2 mg /ml) received the diet and water immediately. The BCAA and IOBCAA poults had higher body weight than those of the C, 48C, and 48BCAA birds. The body weight of the C poults was higher than those of the 48C and 48BCAA birds. The BCAA poults had higher PM muscle weight than those of the C and 48C poults, while that of the IOBCAA poults was higher than that of the 48C poults. The IOBCAA treatment increased the protein content of the PM muscle meat, compared with the C and 48C treatments. The 48C treatment increased the type IIB fiber area and the type I and type IIA fiber percentages but decreased the type IIB fiber, compared with other treatments. The numbers of type IIB and total fibers in the IOBCAA poults were higher than those of the 48C birds. In conclusion, administering BCAAb in ovo or in a starter diet enhanced early growth performance and improved the fiber characteristics of the PM muscle in turkey poults.

In recent years, climate change and Covid-19 pandemic have dramatically caused some attitude variation on consumers’ food consumption preferences. By measuring the impacts on their behaviors of these changes, using as a policy tool is of a great importance. This research was conducted to analyze the total effect of sensory quality and mediating effect with natural risk factor on veal consumption hedonism of consumers in Erzurum province under climate change and Covid-19 epidemic. The main data of the study was consisted of primary data obtained from 385 household in 2021. The data were used in basic effect model to measure the sensory quality effect on consumption hedonism, and then in mediating effect model to determine indirect effects of risk factor playing linking role. The results of the study indicated that sensory quality being of high total effect on consumers’ veal consumption hedonism in basic effect model explained 64% of total variance. On the other hand, it was determined that sensory quality’s direct effect on consumption hedonism in mediating effect model with risk factor was lower, but the risk factor’s indirect effect was meaningful, and had a higher explanation rate than that in basic effect model. In order to be able to increase consumption hedonism, human diets should include consumption based on alternative meat and protein sources of vegetable origin instead of veal consumption. Hygiene decisions minimizing Covid-19 infection risk, moreover, at production and marketing stages of alternative meats should be taken and implemented.

In the current study, thermal degradation and thermodynamic properties of ascorbic acid, total phenolic content, and antioxidant activity of convective dried kiwi fruits were investigated. To determine kinetic model describing thermal degradation of these parameters, zero order, first order, fractional conversion and Weibull model were used. Weibull model gave the best fitting to thermal degradation of these parameters. Moreover, the rate constant of the thermal degradation reaction increased with the increment in drying temperatures, meaning that these degradation reactions were temperature dependent. On the other hand, total phenolic content had the lowest activation energy and ∆H value indicating the lowest thermal stability in comparison to others. The degradation reactions endothermically occurred during drying process. Additionally, it was seen that the reason for the higher degradation rate at higher temperatures as the absolute values of ∆S increased. It is important to evaluate thermal degradation of bioactive compounds for the design of the thermal processes. This study will be beneficial for the convective drying process design due to these results.

Agriculture must be necessary and sustainable for the continuity of human beings. For sustainable agriculture, productive crops can be made with good irrigation in productive crops and conscious irrigation in good irrigation. A survey was conducted with 111 producers in the central district of Tokat province to determine the factors affecting conscious irrigation and conscious irrigation. In the research, first of all, the socio-demographic structure of the producers was determined: it was determined that the producers with an active working population had a low level of education. In the second part of the research, irrigation information was tried to be determined and it was observed that most of the producers were doing salman irrigation. In the third part of the research, irrigation awareness was tried to be determined by using the scoring method of the producers and it was determined that 24% of the producers were in the category with a high level of awareness. In the last part, the factors affecting irrigation awareness were determined with the help of the ordered probit model. As a result, it has been determined that there is a linear relationship between the level of awareness of the producers, their educational status and membership in the irrigation union.

Tahini is a food product that is frequently preferred both directly and as a main ingredient in various ready-to-eat food products and is consumed with interest, especially in the Middle East geography. Its reputation has recently spread across continents to countries like Canada and the United States of America. Tahini was subjected to a number of analyses to ascertain its physicochemical and microbiological quality within the context of the study since it is a highly consumed product with high consumption and demand values. In this context, tahini samples of 10 different brands were collected from producers and commercially sold markets in Balikesir and Bursa. Samples were taken from two different lot numbers for each company. As a result of the analyzes made on the tahini samples, it was determined that the total oil amount of the samples changed between 49.76-58.7%, the salt amount changed between 0.001-0.0027%, the ash amount was between 1.02%-1.28%, and the moisture value was between 1.1-1.5%; as a result of microbiological cultivations in which the presence of yeast and mold were analyzed, an average of 75 CFU/g viability was determined, while Escherichia coli, which was screened as an indicator of fecal contamination, Staphylococcus aureus and Salmonella spp, which are pathogenic microorganisms, were not found to be contaminated in all tahini samples. One of the tahini samples was not found in accordance with the Turkish Food Codex Tahini Communiqué (TFC) in terms of the amount of oil. It is concluded that 90% of the samples were manufactured in line with the TFC when the results of the chemical and microbiological analyses were combined.

Different brewing methods can lead to changes in the physicochemical properties of green tea. In this study, the physicochemical properties of green tea brewed with different amounts (5, 7.5 and 10 grams) and times (5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, and 60 minutes) were investigated. Green tea produced by Çaykur was used in the study. Mineral analysis of green tea samples was performed with ICP-OES, and color analysis was performed with Minolta Spectrophotometer. The antioxidant activity was assessed using the DPPH method and the total phenolic content was determined using the Folin–Ciocalteu method. In terms of mineral content, it was determined highest levels of mineral content (mg/kg) for Al, Ca and Mg (10 g-25 minutes); Fe, Mn and Na (10 g-25 minutes); and B (10 g-50 minutes) as 16.005, 4.099, 24.075, 0.120, 13.855, 1.320 and 0.164, respectively. It was determined lowest levels of mineral content (mg/kg) for Al, Ca, Mg, and Mn (5 g-5 minutes); B and Fe (5 g-10 minutes), and Na (5 g-15 minutes) as 2.756, 1.193, 3.324, 1.23, 0.025, 0.002 and 0.48, respectively. In terms of color, it was determined that the lowest and highest L* values are 39.97 (10 g-45 minutes) -54.23 (5 g-35 minutes), lowest and highest a* values are -2.24 (5 g-5 minutes) (-4.70) (7.5 g-35 minutes) and lowest and highest b* values are 4.91 (5 g-5 minutes)- 23.98 (10 g-60 minutes). The antioxidant activity value (inhibition %) in green tea was found to be the range of 28.51 % (5 g, 45 minutes)- 47.95 (10 g- 40 minutes), and the total phenolic content (mg GAE/mL) was found to be the range of 15.99 (5 g, 5 minutes)- 35.61 (10 g, 15 minutes). The findings determined that green tea brewed with different amounts and times showed statistical differences in terms of color, mineral content, antioxidant activity, and total phenolic content.

Purslane (Portulaca oleracea L.) is an edible wild plant that is widely grown in the world, including Türkiye. Purslane plant, which is an important component of Mediterranean cuisine, can grow spontaneously in nature. Stress conditions can directly or indirectly affect its growth and development in the environment in which it is grown. In the current study, stress conditions of soil organic matter content, irrigation water amount and irrigation water salinity were investigated in pot experiments. The experiments were carried out in a 72 m2 greenhouse established on the Dokuz Eylül University Tınaztepe Campus. From the variables, soil organic matter was applied as 1%, 1.8% (control), 3% and 5% on a dry weight basis. 15 purslane seeds were planted in each pot and left to germinate. Irrigation water amounts were chosen as 100%, 75%, 50%, 30%, 15% of the field capacity. The last variable in the application was determined as the salinity of the irrigation water; the conductivity of the applied irrigation waters were control (tap water-about 0.5 mS/cm), 4 mS/cm, 8 mS/cm, 16 mS/cm. All pots were prepared in four repetitions and the study was carried out with a total of 320 pots. Experiments were carried out for 90 days from the first planting. In the study, it was observed that the increase in organic matter increased plant germination. Statistical evaluation was also made and the effects of irrigation water amount and salinity were also evaluated according to principal component analysis. As the field capacity decreased, decreases were observed in plant growth, but this was mostly observed at 30% and 15% field capacity. The negative effects of salinity on plant growth were observed at 8 mS/cm and 16 mS/cm values.

The aim of this study was to determine the relationships of udder surface temperature (UST) with milk components, and somatic cell count (SCC) in dairy cows during the hot season. The study was carried out with 115 lactating dairy cows (Holstein, Simmental, and Holstein × Simmental) at a private dairy farm in Samsun, Turkey, with monthly visits. The UST was measured from the udder surface before cleaning and milking. At the same time, a portable cell counter and an automatic milk analyzer were used to determine the components and the SCC of the raw milk. The UST values of the cows changed significantly. Increased UST had an adverse effect on milk solids-non-fat (SNF), protein, lactose, and density levels. LogSCC values of cow groups with UST ≤35.0°C, 35.1-36.0°C, >36.0°C were found to be 4.475±0.0803, 4.774±0.1244, and 4.981±0.1491 respectively. The UST negatively correlated with SNF, protein, lactose, density, and freezing point, but positively correlated with LogSCC. As a result, performing UST measurements before milking may be beneficial to monitor udder health and to obtain high quality milk.

This study was performed to determine the effect of hatching system (house and hatcher) and egg weight (heavy and light) on pip-hatch time, hatchability and some gosling quality traits. A total of 389 eggs (fertile of candling) from 2-year-old Turkish Native Goose were used in the study. Before the incubation process, all eggs were individually numbered and weighed. Eggs were divided into heavy (≥160 g) and light (
