The field experiments were conducted at Nematology field, ICR Farm, AAU., Jorhat during 2016 and 2017 to know the efficacy of bioagent, P. fluorescens and biofertilizer, Azotobacter sp. for that P. fluorescens and Azotobacter sp. were enriched in the substrates like farmyard manure, vermicompost and enriched compost. After enrichment of P. fluorescens and Azotobacter sp. were applied singly and in combination at the rate of 1% per hectare (ha). These treatments were compared with untreated control. It was recorded that the combined application of P. fluorescens and Azotobacter sp.

The study was conducted in eighteen NARI Suwarna ewes with the objectives to establish an effective liquid semen sperm concentration for laparoscopic AI and to study the conception rates with natural and laparoscopic AI method in ewes. The ewes in estrus were detected using vasectomized ram and external signs of estrus and were randomly allotted to three equal sized Groups of six each (n=6) namely, natural mating (Group I), laparoscopic AI with 20 million sperm dose (Group II) and laparoscopic AI with 40 million sperm dose (Group III).

In India, rice, wheat and maize yields per hectare of land have increased three to four fold between 1950 and 2010, mainly due to the adoption of improved agronomic practices. Egg production now ranges between 310–320 per annum per bird. Similarly, feed conversion efficiency in broilers is also at par with developed nations and Indian poultry farmers are now more conscious of the need to increase profits by cutting costs and improving productivity. Balancing of nutrients in poultry rations along with improved mineral supplementation has led to this improved productivity.

Within the 2001–7 period, the poultry industry reached its peak in 2003; meat yield was 372 700 metric tonnes and egg production was 4 852 million eggs. Poultry live weight per capita per year was 4.5 kg (equivalent to 2.94 kg carcass weight per person). The number of eggs per capita is 60 eggs, or 3.4 kg of eggs per person (Statistical Yearbook of Viet Nam, 2004), which is lower than in China (6.5 kg), Thailand (15.3 kg), Malaysia and the United States of America (49.6 kg) (author’s calculations). In December 2003, poultry industries in Viet Nam became strongly...

Sperm cells are highly specialized cells that are able to move. Each sperm cell must be able to deliver a haploid set of chromosomes from the male to an egg cell in the female reproductive tract. The structure of a mature sperm cell is well adapted to its function. Almost the entire head of the sperm is the haploid nucleus, the all-important genetic information that is delivered to the egg. Attached to the head of the sperm is a long tail that propels the sperm along.
