We Are Entering a “Golden Age” of Animal Tracking     Golden Age  Animal Tracking       font style='font-size:12px;'> 2015/6/18
Animals wearing new tagging and tracking devices give a real-time look at their behavior and at the environmental health of the planet, say research associates at the Smithsonian Tropical Research Ins...
The results of a study assessing the level of airborne contamination in intensive broiler breeding facilities are presented. The content of corpuscular particulates of various origin (dust, bacteria, ...
Age at first calving is an important trait for achieving earlier reproductive performance. To detect quantitative trait loci (QTL) for reproductive traits, a genome wide association study was conducte...
This study was performed to estimate the effect of age at first calving and first two calving intervals on productive life and life time profit in Korean Holsteins. Reproduction data of Korean Holstei...
An experiment was carried out to determine the effect of age and caponization on the development blood and bone characteristics development in male country chickens in Taiwan. A total of two hundred 8...
Analysis for back fat thickness (BFAT) and daily body weight gains from birth to the end of a performance test were conducted to find an optimal method for estimation of weaning age effects and to asc...
ooth wear and dental pathology related to diet and lifestyle were investigated in the human dental remains unearthed from three archaeological sites of Bronze Age and Iron Age in Xinjiang of northw...
Age, growth, length-weight relationship and reproduction were investigated for striped seabream (Lithognathus mormyrus L., 1758) collected from Beymelek Lagoon (Antalya, Turkey) between February 2006 ...
In this project, ovarian size and activity during the peak (November-April) and the low (May-October) breeding seasons in young and adult camels were studied. Ovaries of 92 camels (Camelus dromedarius...
The aim of this study was to calculate the basic population parameters of Trachurus mediterraneus off the coast of the Eastern Black Sea. Average total length was estimated as 13.52 ± 1.884 cm for the...
In this study, the age and growth of Himri Barbel (Barbus luteus Heckel, 1843) were determined based on specimens collected from Orontes River-Turkey, during the period from February 2004 to January 2...
Totally 189 poor cod (Trisopterus minutus Linn., 1758) specimens were collected by trawling in the central Aegean Sea between April 2001 and March 2002. The relationship of the otolith length and weig...
This study was based on 57 beech marten (Martes foina) specimens collected in Turkey between 1994 and 1998. The specimens were divided into 3 age classes as young, juvenile, and adult on the basis of ...
Leptin is produced by adipocytes and its role in the regulation of lipid metabolism, feed intake, productive and reproductive performance of domestic animal species has been greatly stressed and exten...
This study aimed at targeting fixed increases in body weight (100 g/wk) by quantitatively regulating energy allowances (ME) in broiler breeders from 5 to 20 wks of age. Four energy regimes were tested...
