Abstract Spike fertility index (SF) is a trait easily measured at maturity and strongly associated with the number of grains per unit area. In order to identify genomic regions involved in SF control, biparental (Baguette 10 × Klein Chaja) population 80 recombinant inbred lines (RIL) was used. Seven field trails were conducted determine BLUP value RIL. RILs genotyped using commercial chip (Axio...

background: phenol is an estrogenic and toxic compound and people are widely exposed to it, in different ways.  objectives: the aim of this study was to determine  the  negative effects of phenol on the fertility of male mice, by investigating sperm parameters including viability, motility, fertility rates and daily sperm production (dsp). methods: a total of 106 adult nih mice were divided int...

A genome wide scan was performed on a total of 2093 Italian Holstein proven bulls genotyped with 50K single nucleotide polymorphisms (SNPs), with the objective of identifying loci associated with fertility related traits and to test their effects on milk production traits. The analysis was carried out using estimated breeding values for the aggregate fertility index and for each trait contribut...

The influence of previous sexual experience and subsequent differential housing on the epididymis and fertility index was studied for male Swiss albino cc mice. Among animals with previous sexual experience those having a high epididymal beta-glucuronidase activity showed a high fertility index and vice versa. The reproductive potential of animals without previous sexual experience was reduced ...

The percentage of population below age 6 years is an indirect indicator of the fertility level. In general, a large proportion of population under age 6 is symbolized with higher fertility norms. In other words, its higher proportion leads to young age-structure, i.e., a higher level of young dependency ratio. Therefore, lower the proportion of population below age 6, higher will be the index v...

Summary Fertility estimates from the 1973 Indonesian Fertility Mortality Survey are presented and compared with estimates from the 1971 population census. Although there are some differences, on the whole the two sources are remarkably consistent, indicating the same regional differentials: highest fertility in Sumatra (T.F.R. in rural areas around 7.0), followed by West Java and Sulawesi, Ba...

Background: Phenol is an estrogenic and toxic compound and people are widely exposed to it, in different ways.  OBJECTIVES: The aim of this study was to determine  the  negative effects of phenol on the fertility of male mice, by investigating sperm parameters including viability, motility, fertility rates and daily sperm production (DSP).

Milk production in Thailand has been growing into an important agricultural sector, but it still faces numerous difficulties in environmental constraints. The main intention of this study was to identify significant environmental effects on production and fertility traits to give advices for farm management. Additionally, adjusting records for environmental impact is essential to define appropr...

This paper presents an empirical study of population growth and environmental change using cross-sectional district-level data from South, Central and West India. Environmental change is measured using a satellite-based “greenness” index. Unlike prior work, the analysis treats population and environmental change as jointly determined, distinguishes between rural and urban populations, and ident...
