Effects of dietary fat, vitamin E and zinc supplementation on tibia breaking strength in female broilers under heat stress

The objective of this experiment was to characterize the relationship between dietary fat and antioxidant supplementation, on tibia breaking strength (TS) and performance parameters in broiler chickens under heat stress. The chicks with a similar body weight were equally assigned to one of the two controlled-environment chambers from 21 to 56 days of age. The birds were fed diets as follows: 1) basal diet supplemented...

A field study on negative energy balance in periparturient dairy cows kept in small-holder farms: Effect on milk production and reproduction

Impact of negative energy balance (NEB) and its consequences on milk production and reproduction were studied in 51 dairy cows. All cows were randomly selected from 11 small-holder farms according to their calving date during December 2006 to May 2007. Body condition score and milk yield were recorded. Blood samples were collected from all cows at 2 weeks before expected calving date and at 2 and 4 weeks after calving...

Raising Trissolcus basalis for the biological control of Nezara viridula in greenhouses of Almería (Spain)

The reduction in use of crop protection products in recent years has led to the appearance of new phytophage pests such as Nezara viridula (L.) in the greenhouses of Almería (Spain). Its biological control is, however, possible, and involves the deliberate release of the wasp Trissolcus basalis (Woll.), which parasitizes the pest’s eggs. The aim of the present study was to help meet peak...

Nondestructive detection of moldy chestnut based on near infrared spectroscopy

Chestnut is one of the important agricultural products, especially in Asia. However, a large number of chestnuts are lost due to mildew after harvest. A critical method for preventing and reducing large-scale mildew is to identify and remove moldy chestnuts. Additionally, this procedure plays a significant role in the processing of chestnut-based food product. In this work, we identified moldy chestnuts by near infrared...

Land suitability classification of choice of trees species in District Rahim Yar Khan, Punjab, Pakistan

Pakistan especially in Province Punjab has a narrow forest resource. More than 90% of the fuel wood and almost 50% of timber requirements are being met from trees being growing on the private farm lands, based on agroforestry as compared with the state forests. It is obvious that trees have to be grown in conjunction with agricultural crops on private farm lands. The main objectives of the study pertain to prepare the...

Effect of different harvest methods on olive yield and work capacity

In this research, olives were harvested by four different methods (wood rake, wood stick, mechanical bough shaker + wood stick and electronic harvesting rake + wood stick) and an effort was made to determine their effect on olive yield. From the data obtained during a two year period, the method with the highest work capacity was determined to be the third method (mechanical bough shaker +wood stick), and the...

Effectiveness of phosphorus application in improving regional soybean Yields under drought stress: A multivariate regression tree analysis

Scarcity of water often reduces the regional production of soybean (Glycine max (L.) Merr.) in many areas where it is grown. Contemporary climate change is characterized by increase in frequency and intensity of drought, yet little is known about the successful strategies of soybean cropping systems to drought stress at the regional scale. An effective way to improve the understanding is how to reduce the yields...

Evaluation of agricultural wastes and food supplements usage on growth characteristics of Pleurotus ostreatus

As agricultural wastes are easily accessible and quite free sources, re-use of them could be considered as a break through in production management, especially if it sustains the production efficiency as standard materials do. In this study, we evaluated combination usage of substrates including wood chips, boll, Sugar Beet Pellet Pulp (SBPP) and palm fiber along with wheat bran, rice bran, soya cake powder, Soya Cake...
