Empirical Analysis of Productivity among Broiler Farmers
2022
Godfrey Onuwa
Broiler production supplements income of smallholder farm households. Profitability and productivity and analysis are important considerations in measuring efficiency or performance of a farm business; hence, improved output and income are not only a function of increase in the scale of production, but also how efficiently the resources are being utilized. This study therefore estimates the profitability and level of productivity among broiler farmers in Jos North, Plateau State, Nigeria. Multistage sampling technique was employed to select respondents for this study. Primary data collected were analysed using descriptive statistics, farm budgeting model and Total Factor Productivity (TFP) analysis. The study revealed that the net farm income of broiler production was ₦96,900/flock size; suggesting a relatively profitable venture with prospects for improved economic potentials. The estimated percentage profit margin was 45.6%; indicative of the percentage net margin accruable to the farmer from the estimated gross margin and benefit-cost ratio was 0.84. Furthermore, most (54.3%) of broiler farmers were sub-optimally productive as their TFP indices were below the optimal scale; attributable to sub-efficient input mix and cost of production inputs. In addition, constraints of broiler production in the study area included the following; high cost of feeds (92.9); high cost of chicks (85.7%); financial constraints (80%); high cost of poultry equipment (55.7%); high cost of medication (35.7); disease outbreak (28.6%) and inefficient market system (21.4%). Improving access to and subsidy of poultry feeds, chicks, production inputs and credit, extension, medical services and cooperative formation for market linkages are strongly recommended.

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.

The experiment was conducted in one of the unheated plastic polyethylene (PE) greenhouses of Ege University- Bayındır Vocational Training School -TURKİYE during the winter-early spring of 2019-2020. The goal of the trial was to evaluate the effects of liquid vermicompost (LVC) on Iceberg (Head salad) and Lolo rosso (Lactuca sativa) lettuce in a floating hydroponic system. Two types of growing pools were used as the growing media, one was made of galvanized steel and the other plastic polyethylene. Both pools were covered with a polyethylene at a height of 1 meter from the ground. Lettuce seedlings were transplanted into pools filled with water and a week later Liquid Vermicompost (LVC) and Hoagland Nutrient Solution (HNS) were added to the growing media according to the treatments. The trial was set up in a Randomized Block Design (RBD) with 3 treatments and 3 replications in both of the lettuce varieties. 1. Application: HNS +LVC; 2. Application (HNS); 3. Application (LVC). Lettuce leaves were harvested 84 days after the LVC and HNS applications and prepared for analysis. In this research, in order to determine the impact of liquid vermicompost on Iceberg and Lolo rosso lettuce varieties total yield, marketable yield, the number of leaves discarded, root length and root weights were determined after harvested plants. In both of the lettuce varieties, results indicated that the highest marketable yields were obtained in the first treatment (HNS+LVC). The highest root length and root weight were also determined in the first treatment. It can be concluded that adding liquid vermicompost (100 ml / 100 L water ratio) to the growing solutions of Iceberg (Head lettuce) and Lolo rosso (Lactuca sativa) lettuce varieties, high performances can be obtained.

Gökçen Yakuboğlu | Şebnem Köklü Ardıç | Yakup Cuci | Ahmet Korkmaz
The purpose of this study was to explore the possibilities of improving chilling stress tolerance of eggplant seedlings through exogenous melatonin (MEL) application. Eggplant (Hadrian F1) seedlings were treated with various concentrations (0, 1, 5 or 25 μM) of MEL via soil drench after which they were subjected to chilling stress at 5°C/10°C (night/day) for 3 days. Following stress imposition, the efficacy of MEL applications on enhancing chilling stress tolerance was determined by several physical and physiological measurements and biochemical analyses. The results demonstrated that exogenous application of MEL alleviated the adverse effects of chilling stress in eggplant seedlings. Among the MEL concentrations tested, 5 µM was determined as the most effective concentration since antioxidant enzyme (CAT, POX and APOX) and photosynthetic activities increased while visual and membrane damage decreased in 5 µM MEL-treated seedlings. Also, these results are the first experimental evidence that exogenous application of MEL could improve chilling stress tolerance in eggplant, but further detailed studies are necessary to better understand the mechanism in acquiring chilling tolerance.

Chestnut is an economically important tree because of wood and nut production, which is usually found in warm-temperate species, especially Mediterranean region. The fruit of chestnut is a good antioxidant source besides being rich in vitamin C. Anatolian chestnut (Castanea sativa Mill.) is a natural chestnut species in Türkiye. This study aimed to determine the most appropriate grafting time and grafting method for two chestnut cultivars (Marigoule and Erfelek) collected from the Western Black Sea region. Two different varieties (Marigoule and Erfelek) and three different grafting methods (chip budding, tongue, and cleft) were applied in different environments (in the hoop house and open field) for six months (December, January, February, March, April, and July). Analysis of variance was used for the grafting trials which was established and applied in the factorial trial design. Results showed that grafting success in the hoop house was twice as high in the open field, and the tongue was the most successful grafting method in all months except July. However, chip budding was observed as the most successful method in July. The highest grafting success was achieved in February, followed by July. According to the obtained results, Marigoule (C. crenata x C. sativa) cultivars were more successful than Erfelek cultivars. Marigoule cultivar’s success rate was 86% for the tongue method in February at hoop house. In July, 83% grafting success was achieved.

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.

Free radicals or highly reactive oxygen species are capable of inducing oxidative damage to the human body Plants containing phenolic compounds have potent antioxidant capacity. The present study was undertaken to investigate the in vitro antioxidant activities of Myrtus communis L. (Myrtaceae), a plant widely used as natural remedy for digestive disorders in folk medicine. Total polyphenol contents were determined using Folin Ciocalteu's reagent; flavonoids were quantified employing the AlCl3 Method. EAE extract showed the highest polyphenolic and flavonoids contents (358.37±2.28 GAE/g of dry extract and 105.44±3.48 QE/g of dry extract) respectively. The EAE had the highest antioxidant activity as measured by DPPH radical and hydroxyl radical scavenging activity. EAE and ME extracts exhibited the highest reducing power. EAE possess an IC50 close to BHT (0.074 mg/ml) as reference drug All extracts exhibited antioxidant activity in the linoleic acid emulsion system (76.81% -86.93 %). EAE showed an inhibition ratio of (86.93 %) close to that of BHT (94.9±1.52 %). These findings provide evidence that Myrtus communis L. berries are a potential source of antioxidant which have many benefits towards human health.
