This study was carried out to assess the effect of different cage stocking densities on the production
performance of Nandanam quail III reared up to 42 days. Three hundred day old Nandanam quail
III were randomly assigned to 2.5 x 1.5 ft cages and distributed with 3 treatments (20, 25 and 30
quails per cage or 0.17, 0.14 and 0.11 sq. ft per quail, respectively) and 4 replicates. There were
significant differences among treatments for bi-weekly body weight, feed consumption, feed
conversion ratio and net profit per bird. There was a reduction (P>0.05) in body weight with the
increase in stocking density and the 4th and 6th week body weight were 144.17±3.84, 128.55±3.63
and 108.03±2.69 g; and 216.86±5.95, 207.76±4.01 and 197.27±3.81 g, respectively. The feed
consumption per bird (g) up to 42 days were 665.69±0.01, 532.19±0.01 and 443.23±0.01
respectively. Better feed conversion ratio (2.57 and 2.25) and net profit per bird (Rs. 4.48 and 7.15)
were observed where the birds reared at the cage stocking density of 0.14 sq.ft and 0.11 sq.ft per
bird, respectively. This study concluded that the cage stocking density between 0.11 and 0.14 sq.ft
per bird will be more economical for rearing Nandanam quail III in cage system of rearing up to
42 days of age.
The biological experiment was conducted to study the effect of feeding garlic (Allium sativum) and nilavembu (Andrographis paniculata) in broiler chicken (Vencobb 400) for a period of 6 weeks on various parameters, viz. biweekly body weight, gain in body weight, feed conversion ratio, livability and the cost effectiveness of feeding garlic and nilavembu. A total of 300 day-old, unsexed, broiler chicken were utilized for this study. The treatment groups were fed with diets containing garlic and nilavembu at different levels, such as control (T1), 5 g garlic + 1 g nilavembu (T2), 10 g garlic + 1 g nilavembu (T3), 5 g garlic + 2 g nilavembu (T4) and 10 g garlic + 2 g nilavembu (T5), respectively. Biological experiment revealed that there was highly significant (P<0.01) difference in body weight and body weight gain and feed conversion ratio. No significant difference was observed in feed consumption and livability. The cost effectiveness of the broiler chicken fed with various levels of garlic and nilavembu showed increased net profit per kg live weight in the group fed with 10 g garlic and 2 g nilavembu (T5).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
