Publisher: 1990Dissertation note: The experiment was performed to study the effect of floor space and litter materials on the growth rate, weight gain, feed consumption, feed conversion ratio, dressing percentage and weight of giblets etc. of broiler chicks. One hundred and twenty, day od broiler chicks were used in this study. The experimental broilers were randomly divided into two groups Viz A and B, with each group containing 60 chicks. Both the groups were further divided into 3 sub groups viz AI, AII, AIII and BI, BII, BIII. Every sub group was randomly allotted 20 chicks each.
The experimental chicks were provided floor space of 1.0 and 0.5 sq.foot per bird in groups A and B respectively. Saw dust, rice hulls and cut wheat straw were used as litter material for sub groups AI-BI, AII-BII and AIII-BIII respectively. The chicks were provided same feed and water ad-libitum. All other managemental conditions were same except the floor space and litter materials.
During the experimental period the data for weight gain feed in take and feed conversion ratio was recorded on weekly basis. Then the data was subjected to analysis of variance using randomized complete black design. All the parameters showed non significant difference among the treatments.
However visual observations of the litter in different groups for fitness and maintenance showed, that rice hulls were superior litter as compared to saw dust and cut wheat straw due to less cake formation.
As the results of present study indicates that floor spaces of 0.5 sq.ft/bird and 1 sq.ft/bird do not have any significant effect on weight gain, feed consumption, feed conversion ratio and dressing percentage, so it is concluded that broilers can be reared at the floor space of 0.5 sq.ft/bird without any harmfull effect, in moderate climate. In hot climate sufficient ventilation should be provided to the birds when stock density is increased.
Similarly different litter materials i.e. saw dust, rice hulls and cut wheat straw also showed non significant difference for weight gain, feed consumption, feed conversion ratio and dressing percentage etc. Although cut wheat straw did not prove to be a good litter material for use in broiler houses. However rice hulls and saw dust are approved as good litters for rearing the broilers.

Publisher: 1991Dissertation note: The study was aimed to find out the effect of different photo-periods on the body weight gain, feed consumption, feed efficiency, dressing percentage and Bone; meat ratio of J. quails. Light plays a vital role in the management of quails. The adequate light for quails should be sufficient enough to enable the birds to move about, facilitating to see, eat and drink without any extra exercise. One of the main factors, which needs further exploration is to fix up the hours of light necessary for better growth and economical production.
The present study was thus under taken to determine the appropriate and economical light dark cycle for best performance of Japanese quails, under local climatic conditions. The photo-periods provided in this experiment were 24 hours continuous light, 1 hour continuous light followed by 1 hour continuous darkness alternately, 1 hour continuous light followed by 2 hours continuous darkness and 1 hour continuous light followed by 3 hours continuous darkness to groups Li, L2, L3 and L4 respectively. 192 one day old J. quails were reared upto 6 weeks of age. Groups were further sub-divided into 3 replicates (La, Lb. La) of 16 quails each. The quails of all groups reared in battery brooders, where quails were provided floor space at the rate of 25. SQ. inches per bird, throughout the experiment.
Automatic programme timers with 25 watt bulbs were used; where controlled light was required. Feeding, watering. environmental and managemental conditions were made identical for all the birds. The birds reared under one hour continuous light, followed by 2 hours darkness. Grained more body wiehgt than that of birds of other three groups There were highly significant difference (P<0.01) in body weights of various groups of quails from 3rd to 5th weeks of age.
On applying DMR test, it revealed that the highest body weight was in group L3 followed by Li, L2 and L4 groups respectively.
The results on feed consumption by various - groups were also found to be highly significant (P<0.01)
Maximum feed was consumed by the birds kept under L3 group, followed by Li, L2 and L4 groups respectively. The observations on weekly feed conversion ratio and mortality % were found to be non-significant.
The dressing percentage increased significantly with age. Li group showed better dressing percentage compared with those of other 3 groups. There were highly significant difference (P<0.01) in the dressing percentage among various groups. DMR test revealed that Li group had better dressing percentage, followed by L2, L3 and L4 groups respectively.
The values for bone; meat ratio were found to he highly significant (P<0.01). The best bone; meat ratio were of group Li followed by L2, L3 and L4 groups respectively.
However DMR test revealed that there were non- significant difference observed in bone, meat ratio of groups L3 and L4.
Thus, the fore said study claimed that better productive growth of Japanese quails were under one hour light followed by two hours continuous darkness. There were also comparatively better results of 24 hours continuous light as compared to be L2 and L4 groups in our study.

print
Publisher: 1993Dissertation note: The present study was under taken to investigate the effects of substitution of fish meal which is comparatively costly protein supplement with the soybean oil meal on the performance of Broiler chicks. One hundred and eighty day old (Male and Female) hubbard chicks were purchased from local market and were reared on four experimental rations A, B, C, & D upto fifty days of age. The starter rations were fed upto 28 days of age and the finisher rations were fed from 29th to 50 days of age.
Results revealed non-significant difference among weight gain and feed consumption of chicks fed on different experimental rations.
Apparently better feed utilization was noticed by the chicks fed on ration C (8 percent soybean oil meal and 4 percent fish meal. Statistically non significant difference were observed in the feed efficiency value of chicks fed on different experimental rations.
The present result revealed that chicks fed on ration C (8% soybean oil meal and 4% fish meal) apparently showed increased growth of broiler chicks, required less amount of feed per unit weight gain and were economical as compared to birds fed on other experimental rations.

Publisher: 1996Dissertation note: The present study was undertaken to investigate the effect of different levels and sources of fish meals on the performance of broiler chicks. One hundred and eighty day-old hubbard chicks were randomly divided into 18 experimental groups of 10 chicks each. The chicks of two commercially available fish meals with three levels of Gwadar and Sindh fish meals were compared in this study. The chicks were assigned to 6 experimental rations in such a way that there were three groups of 10 birds each under each ration. Th starter rations were fed upto 0-28 days of age while the finisher rations from 29-42 days of age. At the end of experiment three birds from each replicate were taken at random and slaughtered to find out the dressing percentage.
The average weight gain of chicks fed on Rations A, B, and C (containing Gwadar fish neal) were 1879.2, 1770.65 and 1712.82 gms respectively. The maximum weight (1879.52 gms) was observed in ration A (containing 8 percent fish meal). The average weight gain of chicks fed on rations D, E and F (containing Sindh fish meal) were 1697.78, 1644.5 and 1677.9 gms respectively. The maximum weight gain (1697.78 gms) was observed in ration D (containing 8 percent fish meal). The average weight gain by chicks fed on two different sources of fish meals; i.e. Gwadar and Sindh were 1787.844 and 1673.411 gms respectively.
Results revealed significant differences between the two sources and non-significant difference among the various levels of fish meals for weight gain data which showed that Gwadar fish meal was better as compared to Sindh fish meal and apparently 8 percent level was better than 11 and 14 percent levels of fish meals.
The average feed consumption of chicks fed on rations A, B, and C (containing Gwadar fish meal) were 3560.1, 3540.16 and 3373.49 gms respectively. The maximum feed consumption (356b.1)was observed in ration A (containing 8 percent fish meal). The average feed consumption of chicks fed on rations D, E and F (containing Sindh fish meal) were 3535.6, 3374.3 and 3462.73 gms respectively. The maximum feed consumption (3535.56 gms) was observed in ration D (containing 8 percent fish meal). The average feed consumption by chicks fed on two different sources of fish meals i.e. Gwadar and Sindh were 1929.74 and 18&6.777 gms respectively.
Feed consumption of chicks fed on rations containing two sources of fish meal were non-significant. On the other hand there was significant differences in feed consumption of chicks fed on rations containing various levels of fish meals. Apparently better feed consumption was observed in Gwadar fish meal as compared to Sindh fish meal.
Statically non-significant difference was observed in the feed efficiency value for both different sources and various levels of fish meals. Apparently Gwadar fish meal had better feed efficiency than Sindh fish meal while in case of levels 8 percent had better feed efficiency as compared to 14 and 11 percent respectively.
