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: 1994Dissertation note: A study was undertaken to investigate the influence of varying levels of protein and energy on the performance of broiler chicks. The performance of chicks were studied under the heading of weight gain, feed consumption, feed efficiency, dressing percentage, organs weight, abdominal fat and economics.
Nine experimental rations containing metabolizable energy 2600, 2900 and 3200 Kcal ME/kg with 18, 20 and 22% crude protein were tried on two hundred and seventy day old broiler chicks of both sexes for the period of 50 days.
The results showed that the ration containing 20% C.P. and 2600 KCal ME/kg were best in promoting weight gain, feed utilization and were economical as compared to other experimental rations.
Different energy-protein levels did not influenced the dressing percentage and organs weight, but the diet containing high energy resulted significantly more deposition of the abdominal fat.
It was concluded that low energy and high protein combination in poultry feed formulation improved the growth rate, feed efficiency, feed conversion ratio and could be economical as compared to the high energy and high protein ration.

It was concluded that low energy and high protein combination in poultry feed formulation improved the growth rate, feed efficiency, feed conversion ratio and could be economical as compared to the high energy and high protein ration.

Publisher: 1988Dissertation note: The study was conducted to determine the effect of heat treatment and lysIne supplementation on the nutritive value of sunflower meal (SFM) , through biological trial, on the broiler chicks. It also included the estimation of lysIne contents of sunflower meal processed at different temperatures.
Two research experiments were conducted on day-old broiler chicks to evaluate the nutritive value of sunflower meal processed at different temperatures and subsequently supplemented with lysine. In the first experiment SFM was subjected to various heat treatments at 90°, 10.0°,110°, and 120° for 30 minutes. The results indicated an improvement in growth rate of the chicks fed ration H containing SFM processed at 90°C, while the chicks fed ration III to V containing SFM processed at 1000,1100 and 120°C showed a proportionate depression in weight gain, which might be due to the damage or unavailability of heat labile essential amino acid lysine. There was a non-significant difference in the feed consumption of chicks fed different experimental rations. The chicks fed ration II containing heat treated SFM at 90°C showed the best cumulative feed efficiency as the processing temperature of SFM was increased. The carcase weight of trie chicks fed different experimental rations showed almost the same trend as observed in "weight gain. However, a non-significant difference was observed in the dressing percentage and weight of internal organs of the chicks.
In the second experiment, chicks fed ration I containing SFM processed at 90°C showed the maximum weight gain while chicks fed rations II, IV and VI containing SFM processed at 100°, 1100 and 120°C showed a proportionate depression in the weight gain as well as feed efficiency. It might be attributed to the damage or unavailability of heat labile essential amino acid lysine. The depression in weight gain and feed efficiency of the chicks due to feeding of heat processed SFM was alleviated when fed rations II, V and VII, containing SFM processed at 1000,1100 and 120°C and supplemented accordingly with the synthetic lysine. The carcase weight of the chicks showed almost the same trend as observed in the weight gain. However, dressing percentage and weight of Internal organs of the chicks showed a non-significant difference. The lysine estimation of sunflower meal processed at 90°, 100°, 110° and 120°C revealed that the lysine content was proportionately decreased by 10,10.9,12.15 and 14.55 percent respectively. The results were substantiated through the biological trail of feeding heat processed sunflower meal to the broiler chicks, which showed that the weight gain and fee efficiency of the chicks were significantly improved when the heat processed SFM was supplemented with the corresponding amounts of synthetic lysine.
CONCLUSION
Two experiments were conducted to determine the effect of heat treatment at 900, 100°, 110° and 1200 and lysine supplementation of heat processed sunflower meal (SFN) on the growth rate, feed consumption, feed efficiency, dressing percentage and weight of internal organs of the chicks.
The weight gain and feed efficiency were proportionately reduced when processing temperature was increased from 100°C onwards. The lysine supplementation improved the depressions significantly as was reflected in better weight gain and feed efficiency of the chicks. It indicated that heat processing made the lysine unavailable, which was confirmed through the analysis of lysine content of SFM.

Publisher: 1990Dissertation note: Although poultry industry is dynamic for having tremendous potential to produce quality protein from meat and eggs which has a significant impact on the economy of our country. Yet it is not a stable business because a slight variation in environment upsets its profit margins. Different lighting schedules play a prominent role for rearing the broiler birds. In recent years efforts have been made to develop more efficient lighting schedules so as to save the electricity expenditure and to produce cheaper broiler meat.
An experiment therefore, was designed to work out an ideal lighting pattern.
In this experiment two hundred and twenty day old chicks were reared together for the first fifteen days, then one hundred and eighty chicks were randomly selected and subjected to different lighting patterns and clours of red, green and normal lights. They were divided in to groups i.e. A,a B,b and C,c exposed to continuous and intermittent pattern of red, green and normal light.
The maximum weight gain was obtained by group subjected to green continuous lght and the lowest by group exposed to normal intermittent light. Likewise the maximum amount of feed was consumed by the group provided normal continuous light and minimum by the group exposed to red intermittent light. So far as the FCR is concerned, it was comparatively better in green continuous light group and poorest in normal intermittent light group. Another purpose of this experiment was to observe whether coloured and intermittent pattern of lights have better effects than that of the normal ones. The chicks subjected to green continuous light gave better body weight and FCR as compared to all other treatments. The results of the experiment suggest that we can save both electricity and feed by rearing broilers under continuous green lighting pattern.
