Imoleayo Sarah Oladeji | Muyiwa Adegbenro | Innocent Bamidele Osho | Olumuyiwa Joseph Olarotimi
Over the years, the growing concerns about the negative impact of anti-microbial growth promoters has triggered researches into the use of phytogenic feed additives in poultry production in order to ascertain better performance of birds as well as safety in the food chain. Phytogenic feed additives are compound derived from varieties of plants, its parts, extracts and essential oils which possess active substances that are of significant importance. Some of its functions include anti-microbial and anti-oxidative effects on the poultry feeds and carcass as well as enhancement of flavour of feeds. Despite the beneficial influences of PFAs, numerous controversial issues have emerged on the appropriate dosage to be used in poultry production. This may be due to the differences in edaphic and climatic actions on plants available in various part of the world and stage of harvesting of plants which makes standardizing inclusion levels of phytogenic feed additives in poultry diet seemingly difficult. However, it is crystal clear that phytogenic feed additives qualify as a better substitute to anti-microbial growth promoters as it is safe and ecologically friendly.

This research was conducted to determine forage yield, chemical composition, milk yield and milk composition in dairy cattle grazing on pasture established with species and mixtures of Perennial ryegrass (Lolium perenne, Bastion,PR), Orchardgrass(Dactylis glometata, Pizza,OG) and White clover(Trifolium repens, Huia,WC). In this research conducted for two years, the grazing experiment was carried out according to a change over trial design. For this purpose, a total of 6 Holstein Friesian cows (at the 2nd lactation and with an average of 520 ± 26 kg live weight) were used for two periods, each of which consisted of 30 days (8 days of adaptation and 22 days of the basis period). The milk nutritional composition of the animals (dry matter, fat and protein content) was determined in the last three days in the last five consecutive days of each lactation period. The acid detergent fiber (ADF) content of pasture obtained from Perennial ryegrass + White clover mixture (PRWC) was found to be lower than that obtained from the other two (PR and OG) pasture and Net Energy Lactation (NEL) content was found higher in the first grazing period in the first year. However, the effect of the investigated pastures on milk yield was not significant, but it was found that the effects on milk protein yield in the first year and dry matter of milk in the second year were significant. In the first year of grazing period, milk yield, milk fat yield and protein yield were found to be significant. The results of this study showed that under these operating conditions, the botanical composition of the pasture had no effect on the amount and composition of the milk, but the milk yield decreased as the vegetation period advanced.

β-thalassemia major is severe hemolytic anemia which requires repeated blood transfusion and for survival, which leading to iron overload. Serious complications due to iron over load are recognized in the thalassemia patients. objectives Vitamin D and calcium are important factors for homeostasis of calcium in this study. This study was conducted for a period of two year including from patients with β- thalassemia major from Duhok Thalassemia Centre between 2014 -2015. Thirty eighth β- thalassemia major patients and thirty eighth persons with age- matched as control group were enrolled in the study. Serum concentration of 25- hydroxy vitamin D and calcium were estimated by enzyme linked fluorescent assay and colorimetric method, respectively. In patients, the level of serum 25- hydroxy vitamin D was significantly lower 11.11±4.36 ng/mL compared with control group (14.03±5.96ng/mL). Vitamin D deficiency is observed about 94.73% in patients. The mean level of serum calcium in patients group is 7.9±0.47mg/dL and 8.98±0.77 mg/dL in control group. There was a statistically significant difference in serum calcium value between patients and control group. 44.73% of patients have hypocalcaemia. This study demonstrated a high prevalence of Vitamin D deficiency and low total serum calcium levels in thalassemia patients with a significantly lower than healthy group. Hypocalcemia and vitamin D deficiency may be results from the negative effect of the repeated blood transfusion and malnourishment.

Pothohar region of the Punjab, Pakistan is rain-fed with undulating topography. Soils of the area are predominantly loose with low water retention capacity and are vulnerable to erosion. Erratic and high intensity rainfall causes land erosion in the area producing gullies and gorges. Therefore, agriculture in the area faces twin menace of soil erosion and moisture stress. On-farm water control structures are among the important measures to control soil erosion and conserve moisture to enhance agriculture productivity. Present study was designed to evaluate the impact of these structures on soil moisture conservation and physio-chemical characteristics of soil in wheat growing fields. Wheat was sown in the fields, with and without structures during 2009 to 2013. It has been found that construction cost of such structures is about one-fourth that of conventionally used structures in the area whereas reduction in soil erosion has been observed up to 10% with 21% soil moisture conservation as compared to control. Soil fertility level improved significantly as a result of reduced run off and nutrient loss. A substantial improvement in wheat yield up to 15% due to increased fertility and moisture content was also recorded. These structures facilitated a safe disposal of surplus rain water which minimized the gully development, improved the soil structure, checked fertility loss and improved soil moisture retention.

İsmail Özaşık | Mehmet Demir Kaya | Engin Gökhan Kulan
Seed viability and vigor have been influenced by several factors including soil and climatic conditions, plant nutrition, fertilization, irrigation, plant population and post-harvest storages. The study was conducted to determine the appropriate plant density for vigorous seed production in safflower. The effects of row spacing (14 and 28 cm) and seeding rate (40, 80, 120, 160 and 200 seeds m-2) on yield, yield components and seed quality of safflower were detected in the study. The results showed that increased seeding rates resulted in enhanced seed yield and the highest seed yield was obtained from 14 cm and 200 seed m-2 with 3320 kg ha-1. The row spacing and seeding rate did not cause a significant difference in oil and protein contents. Laboratory emergence, germination after accelerated ageing (AA) and electrical conductivity tests were suitable for determining seed quality among the seed lots, while standard germination, cool and cold tests were not appropriate. The highest laboratory emergence percentage and germination after AA were determined in 80 seed m-2 but field emergence percentage in 120 seed m-2. It was concluded that the 14 cm row spacing and seeding rate of 120 seed m-2 should be advised for high yielding seed production regardless of seed vigor in safflower.
