Cotton being the most important fiber crop in Pakistan plays an important role in economic stability of Pakistan. Better quality and high yielding cotton varieties are needed to meet the demands of the national and international markets. An insight into the genetic diversity and correlation among the various traits related to yield is helpful in this regard. Results of path coefficient analysis revealed that petiole length, number of bolls per plant, boll weight, number of seeds and seed index played a pivotal role towards the seed cotton yield of plant as these traits exerted direct positive effect on yield while the traits viz; plant height, number of monopodia, number of sympodia, nodes on 1st fruiting branch, leaf length per width ratio, number of locks per boll, 1000-seed weight, fiber length, fiber strength, fiber fineness and GOT were found to have deleterious role towards the yield per plant as these exhibited direct negative effect on seed cotton yield.

Cyanide is widely distributed in the ecosystem and has been linked with lethal effects in animals as well as humans. Cyanide toxicity may be the result of intake from food sources, environmental pollution, intentional ingestion, chemical warfare, occupational exposure, homicide, and sometimes through the use of drugs like nitroprusside and laetrile.Cyanide intake has been linked to central nervous system syndromes and thyroid in animals as well as humans. This book covers the following aspects. 1) cyanogenic potential of various sorghum species. 2) cyanide levels in blood samples of cattle, buffaloes, sheep and goats feeding on cyanogenic plants. 3)new simple, reliable and inexpensive assay to determine CN levels in blood samples. 4)efficacy of various antidotes against cyanide toxicity. 5) effects of cyanide toxicity on hematological and biochemical panel. 6) postmortem lesions and histopathological changes associated with cyanide toxicity in various organs. 6) alterations in tissue oxygenation and metabolic variables during acute cyanide toxicity."

Donkeys are extremely valuable animals in Pakistan because they are increasingly used in transportation of goods, cultivation of lands and are one of the cheapest sources of labour. Donkeys are extremely important as their use is much more in transportation and labour as compared to horses. Donkeys have a major socio-economic importance in many areas. Despite the advancement in mechanization, donkeys are still the "beasts of burden." Under smallholder farming system, donkeys are the most precious, suitable and economical animals, because they can be used in areas with coarse topography and underdeveloped roads. Strongylosis is one of the most important diseases of equines. Diarrhoea, anorexia, weight loss and marked anaemia are the clinical signs in infected animals resulting in huge mortality. The mixed strongyle infections are common in donkeys with clinical signs including anaemia, diarrhea and unthriftness.
