Supplementation programs for prepartum beef cows are usually adopted because the nutritional status of the cows upon calving is a main factor impacting reproductive performance of the next production cycle. This study evaluated the effects of 60-d pre-partum energy-protein supplementation on performance, metabolic and hormonal responses during the peripartum phase of grazing beef cows.

Inflammatory diseases of reproductive tract in bitches are a common problem in veterinary practice. The inflammation can lead to serious health problems. Research to determine the correlation between the health status of females, phase of the cycle, age and bacterial flora of the genital tract has been ongoing for years, but the results obtained by individual authors are often contradictory.

SQUAMOSA promoter binding proteins (SBPs) genes encode a family of plant-specific transcription factors involved in various growth and development processes, including flower and fruit development, leaf initiation, phase transition, and embryonic development. The SBP gene family has been identified and characterized in many species, but no systematic analysis of the SBP gene family has been carried out in sugarcane.

Flagella have been lost in the vegetative phase of the diatom life cycle, but they are still present in male gametes of centric species, thereby representing a hallmark of sexual reproduction. This process, besides maintaining and creating new genetic diversity, in diatoms is also fundamental to restore the maximum cell size following its reduction during vegetative division. Nevertheless, sexual reproduction has been demonstrated in a limited number of diatom species, while our understanding of its different phases and of their genetic control is scarce.

The goat is an important farm animal. Reproduction is an important process of goat farming. The ovary is the most important reproductive organ for goats. In recent years, an increasing number of long non-coding RNAs (lncRNAs) have been implicated in the regulation of mammal reproduction.

During initial characterization, we observed significant reproductive cycle-based variation in infection outcome. When uterine infection occurred in the diestrus phase, there was significantly greater pathology than during estrus phase. The aim of this study was to evaluate transcriptional profiles of infected uterine tissue from mice in either estrus or diestrus phase in order to elucidate possible mechanisms for these differences.

PhasiRNAs (phased secondary siRNAs) play important regulatory roles in the development processes and biotic or abiotic stresses in plants. Some of phasiRNAs involve in the reproductive development in grasses, which include two categories, 21-nt (nucleotide) and 24-nt phasiRNAs.

Improving sow fertility is extremely important as it can lead to increased reproductive efficiency and thus profitability for swine producers. There are considerable differences in fertility rates among individual animals, but the underlying molecular mechanisms remain unclear.

Baby corn is the ear and diversified product of maize plant harvested young, especially when the silks have either not emerged or just emerged, and no fertilization has taken place. Field experiments were conducted during October-March, 2012-13 and 2013-14to study the impacts of thermal regime on phenology and yield of baby corn. Thermal environment during reproductive phase of baby corn contributed more towards the yield formation process, as compared to that during vegetative phases.

A two year field study was conducted at Agricultural Research station, Ragolu to study the efficacy of selected agrochemicals on the development of diseases (sheath rot, brown spot and grain discolouration) during reproductive phase in paddy. Treatments were imposed for two times, once at 50% panicle emergence and 15 days subsequently.

The inductive response of H2O2 scavenging enzymes was studied in leaves of twenty rice cultivars when the plants were exposed to elevated temperature 55 days after transplanting (DAT). High temperature stress preferentially enhance the activities of ascorbate peroxidase (APX) and non-specific oxidase (POX), catalase (CAT) activity decreased with continuous exposure to heat stress although it was higher than control upto 15 days of stress (DAS) treatment.

The present study was carried out in sixteen genotypes having different aptitude for tolerance to stress. Drought stress was imposed at early reproductive phase of growth. Despites of reduction in plant height and number of tillers, genotypes have shown least reduction in the grain yield under drought stress.

Banana is a highly exhaustive crop which requires large quantities of mineral nutrients for rapid growth and development, thus it readily responds to applied nutrients. Major nutrients like nitrogen, phosphorus and potassium play an important role in the vegetative and reproductive phases of crop growth, depending on the cultivar.

Dairy farmers prefer different floor type like rubber, stones, gravels, bricks, concrete, mates and mattress etc. for providing comfort to the animals according to their own status. Poorly designed stall and bedding facilities cause an increased risk of productive, reproductive performance and lameness in dairy animals including decrease in there resting phase (Cook et al., 2009). Depth and height of bedding materials is also an important factor for dairy cows comfort.

Thirteen rabi sorghum genotypes were studied for root traits in rabi 2013-14 at All India Sorghum Improvement Project, Mahatma Phule Krishi Vidyapeeth, Rahuri in Phule Root Box Structure under receding soil moisture. The genotypes were sown on exclusively receding soil moisture under rainout shelter. The results of soil moisture status revealed that the soil moisture gradually decreased from sowing till the harvest of crop. The moisture depletion was less at vegetative phase as compared to reproductive phase. The sharp decrease with increasing depth was observed at reproductive phase.
