In recent years, egg production has had an intense growth in Brazil, and Brazilian consumption per capita significantly increased the last decade. To reduce sanitary financial risks, decisions regarding health status of flock must be made based on objective criteria. Our aim was to determine main “input” variables for prediction performance commercial laying breeder flocks using ANN model. The ...

The tadpole shrimp, Triops cancriformis, is a freshwater crustacean listed as endangered in the UK and Europe living in ephemeral pools. Populations are threatened by habitat destruction due to land development for agriculture and increased urbanisation. Despite this, there is a lack of efficient methods for discovering and monitoring populations. Established macroinvertebrate monitoring method...

In this study, two following experiments were performed to improve post-thaw motility and viability of frozen-thawed ram spermatozoa. We examined i) the effects of different concentrations of bovine serum albumin (0, 0.3, 1, 5, 10 and 15% BSA) in semen diluents lacking egg yolk and ii) the effects of four semen diluents, fructose (F: control) and trehalose (T) in semen diluents containing egg y...

Goats are small ruminants that reared by the rural community for financial income and nutrition. This study was aimed to determine effect of vitamin C addition in tris–egg yolk extender on lifespan Sapera goat spermatozoa stored 5o C. Semen collected from 1.5 years old male goat. The ejaculates were diluted Tris-egg (T-EY) added with 0, 0.2, 0.3, 0.4 g C/mL T0, T1, T2, T3 groups, respectively. ...

objective: both the length of extra-alveolar time and type of storage media are significant factors that can affect the long-term prognosis of replanted teeth. this study aims to compare propolis 50%, propolis 10%, hank’s balanced salt solution (hbss), milk and egg white on periodontal ligament (pdl) cell survival for different time points. materials and methods: in this in vitro experimental s...

The contamination levels of Toxocara spp. eggs in soil samples from a university campus in Mexico City were evaluated and analysed according to garden size, and were related with the percentage of Toxocara spp. eggs and its viability according to the soil characteristics. A total of 1458 soil samples collected in 15 gardens (six large and nine small) were analysed by sedimentation-flotation wit...

This study aimed to analyze the effect of Alpinia purpurata K. Schum rhizome extract (APRE) supplementation into tris-egg yolk extender on sperm quality Bali bull after freezing. used experimental method with a completely randomized design (CRD), consisting five treatments, denoted as P0 (semen diluted using 100% Tris-Egg Yolk (TEY)), P1 98% TEY and 2% APRE), P2 96% + 4% P3 94% 6% P4 92% 8% APR...

The objective of this study was to evaluate quality of frozen-thawed bull semen processed with extenders containing vitamin C and E as antioxidants. Pooled semen's were collected from 5 bulls and diluted to a concentration of 30 × 106 sperm/mL with citrate –egg yolk (CEY) or Tris – egg yolk (TEY) extenders. The diluted semen was divided to 5 aliquots including control and 4 experimental groups....

The aim of this study was to evaluate the effects of dietary vitamin E on reproductive and productive parameters in Japanese quails. A total number of 240 female and 80 male Japanese quail were divided into five treatments with four replications in a completely randomized design. Experimental diets were zero control, 30, 60, 120 and 240 mg kg-1 of vitamin E. Fertility and total hatch...
