... more Data on growth of bunnies born in to 112 litters of two synthetic rabbit genetic group APAU Fawn and APAU Black, were utilized for the present investigation to evaluate in uence of genetic and non-genetic factors on post weaning growth. Effect of genetic group was signi cant at 16 week of age on Body Weight (BW) and the same was observed on Average Daily Gain (ADG) at 12 and 14 week. Effect of season was signi cant on BW and ADG at most of post weaning ages studied. Litter size at birth exerted a signi cant in uence on BW at 6 week, while its effect on ADG was limited to 6 and 14 week.

Genetic group and season did not exert significant influence on litter traits except for significant (P≤0.05) genetic group effect on litter weight at birth and 1 week of age.

Endogenous L-Arginine (L-Arg) and L-Citrulline (L-Cit) are physiological amino acids in most living systems which act through NO-cGMP pathway and result vasodilation. Hence, the antioxidant property of NO donors L-Arg and L-Cit were evaluated against the vascular damage induced by cyclosporine A, along with HFD that serve as a model to induce Atherosclerosis followed by the vascular damage caused by CsA in C57BL/6J mice for 90 days. Antioxidant profiles (SOD, catalase, GSH, GSH Px and TBARS) were assessed in aorta, kidney and liver tissues at the end of experiment. L-Arginine and L-Citrulline administration resulted significant improvements in all the antioxidant parameters. The effects of L-Arginine were comparable to L-Citrulline, while the combination of L-Arginine and L-Citrulline was found superior in this study. Hence, with this present study, it could be concluded that, the ability of nitric oxide boosting substances, including L-Arg and L-Cit are having antioxidant effect and could reverse the progression of vascular disorders induced by cyclosporine along with HFD.

Rabbit domestication dates back to late middle ages, which were discovered by Phoenicians on the shore of Spain. It were Romans who spread rabbits as game animal throughout. It all started with keeping rabbits in stone walled pens or parks called as leporaria. By sixteenth century several breeds of rabbits were developed through controlled breeding. It is during the same period that rabbit rearing and breeding spread to Italy, France and England. With beginning of nineteenth century rabbit rearing in hutches sprang up all over rural Western Europe and also reached Australia and New Zealand with European colonial expansion. During its initial stage of expansion rabbits were fed on green forage, hay, beetroots and grains. They were reared in backyard along with poultry for meat and fur.

The effect of genetic group was significant limited to a particular period of study. Season of birth exerted highly significant influence on body weight gained, with winter proving to be the promising period for growth. Litter size at birth was found to exert influence on body weight gained by each bunny in a group, with smaller groups gaining more. Genetic group, Season of birth and Litter size exerted a significant influence on Average Daily Gain (ADG) of bunnies. The overall pre-weaning mean body weight at first and fourth week ranged from 51.30 ± 0.38g to 476.39 ± 5.43g, respectively, whereas the ADG ranged from 8.86 ± 0.15g to 29.52 ± 0.73 g, for the same period.

They are medium sized and dual purpose strain of goat. A study was conducted to estimate morphometry and performance traits of local Mahbubnagar goats reared under field conditions. In total, flocks (n=2657) with 44 farmers distributed throughout the native tract were studied to measure the above said traits. The average flock composition ranged from 20-130 in size, with bucks constituting 10-85%, does between 10-25% and kids ranging between 8-37.5%. Ears were pendulous. Beard was present only in males while both the sexes had wattles. Both the sexes were horned with backward orientation. Body weight at birth ranged between 1.8-3.0 kg, at weaning (3 months) 7-14 kg, at 6 months of age 17-28 kg, at adult 26-40 kg. The weight of doe at first kidding ranged between 26-40 kg. With respect to body measurements in adult goats, the chest girth ranged between 58-105 cm, body length between 55-96 cm and height at withers between 58-103 cm. The total milk yield was between 22-60 litres per lactation, while lactation length was between 60-120 days. Age at first mating in males was between 360-540 days, while the same in females was between 320-380 days. Age at first kidding was between 520-600 days, while kidding interval was between 180-280 days. The average litter size was 2, while the no. of kid's lifetime ranged between 7-11.

As per FAOSTAT, 2014 leading producers of duck meat in the world are China followed by France, Malaysia, Myanmar and Vietnam.Of the total ducks reared in India 90% are indigenous and form the second largest species contributing for egg production. As per, livestock census 2007 in India ducks constituted about 8.52% of total poultry population and counted for about 27.43 million in number.In India, West Bengal, Assam, Kerala, Andhra Pradesh and Tamil Nadu are the leading states in duck population. Ducks are reared for egg, meat and the size of egg is about 4.5% of ducks body weight whereas, that of poultry is 3.3 % of its body weight. Ducks are more prolific compared to chicken and are more adapted to free range system of rearing. Duck rearing in India is concentrated in the hands of small and marginalized sections of society and has not seen the light of industrialization as in case of poultry. The states along the coastal belt of India with inland water resources provide the required natural potential for duck rearing. Considering the hardiness, active foraging ability, adaptability of the ducks to grow in free range system and the less cost input in rearing them, these act as a reliable source of livelihood for many poor rural farmers. ADVANTAGES OF DUCK REARING: 1. They require less care, attention and lay eggs which are heavier that poultry eggs by about 15-20 gram. 2. Comparatively ducks have more economic egg laying life than poultry 3. They are hardy, more resistant to diseases compared to poultry and can grow in marshy and wet lands which are not adaptable for rearing other domestic animals. 4. They lay eggs at early hours of day, do not require extensive housing system and are free from cannibalism and other vices. 5. Ducks feed on insects, bugs, snails and for this reason integrated farming of duck with fish and duck with paddy cultivation is suggested to be economical.
