Publisher: 1989Dissertation note: The study was aimed to find out the incidence of lameness in broilers at different age groups under different management conditions in and around Lahore.
The project was devided into two parts.
1. Research Work
2. Survey Work
Research Work
In research two hundred broilers chicks were reared in the college. They were brooded uniformly for two weeks. Then 162 birds were selected randomly and divided into three treatments i.e. A, B and C on the basis of depth of littre i.e. 1 inch, 2 inches, and 3 inches respectively. The parameters studied were weight gain, lameness and mortality from 3 weeks to 6 weeks age.
Weekly data starting from 3rd week onward revealed that the treatment C having 3 inches depth of littre gained more weight, less leg lameness and differed highly significantly (P<0.01) from B and A.
Survey Work
In Survey Work three data from types of farms I, II and III (Houses having length less than 50 feet, width less than 30 feet and window height less than one foot from the floor)(Houses having length in between 50-70 feet, width 30 feet and window height 1-2 feet from the floor) and (Houses having length more than 70 feet, width more than 30 feet and window height more than two feet from the floor were collected and analysed.
The study was based on three different age groups i.e. 3 weeks, 6 weeks and 7 weeks. The study revealed a highly significant difference (P<0.01) in three age groups. Three weeks age group showed least leg lameness. A highly significant difference was also observed between age groups of 6 weeks and 7 weeks. This difference is because broiler start gaining weight rapidly after 5 weeks.
A significant difference was also observed in all the Specification. A highly significant difference was observed between specification I and III and II and III. No Significant difference was observed between specification I and II. It was observed that as the length, width and window height from the floor increased the leg lameness also increased.
There was no mortality throughout the experimental period.

Publisher: 1991Dissertation note: R ice polishing is the finally ground powdered material obtained in the polishing of kernels of rice after the hulls has been removed. Rice polishing furnishes almost equivalent energy as other cereals and at the same time is a good source of protein and water soluble vitamin especially Thiamine and Niacin. Its fiber content is comparatively higher than the cereal grains. It also contains a considerable amount of oil which is Viable to become rancid, if stored for longer period, so its oil should be extracted to improve its quality and to store it for a longer period. Rice polishing (sol. ext.) at present is not utilized efficiently for feeding of poultry due to presence of certain growth inhibitory factor.
The present study was planned to replace maize with rice polishing (sol. ext.) at different levels in the broiler rations and to find out suitable treatments of autoclaving to reduce/remove the growth inhibitory factors. Two experiments were conducted using day old "Indian River" broiler chicks as experimental birds.
In the first experiment the replacement of maize with rice polishing (sol. ext.)at different levels was studied. Growth rate, feed comsumption, efficiency of feed utilization and dressing percentage of chicks were recorded.
There was a non significant difference in weight gain of chicks fed rations containing 0, 10, 20 & 30 percent rice polishing (so!. ext.). However, the feed utilization was reduced significantly (P < 0.01) as the level of rice polishing (so!. ext.) was increased in the rations.
In the Experiment II, effect of different treatments on the nutritive value of rice polishing (sol. ext.) was studied. Treatments included autoclaving for 30 minutes, autoclaving for 60 minutes and autoclaving for 30 minutes with 20 percent moisture. autoclaving treatments significantly (P < 0.01) improved the growth rate and feed efficiency of chicks as compared to the control ration (without autoclaving). Best weight gain and feed efficiency was found in the chicks fed ration containing rice polishing (sol. ext.) autoclaved for 60 minutes. This indicated that autoclaving had reduced/removed the antinutritional/growth inhibitory factor(s) present in the indigenous rice polishing. The autoclaving with 20 percent moisture was in effective to further improve the nutritive value of rice polishing for broilers.
CONCLUSION:
The findings indicate a significant growth depression along with poor utilization of feed by chicks fed rations containing higher levels of rice polishing (sol. ext.).
Autoclaving treatments improved the nutritive value of rice polishing (sot. ext.), as indicated by better growth rate and feed utilization of the chicks. Autoclaving with increased, moisture was ineffecting in further improving the nutritive value of rice polishing for broilers.

Publisher: 1992Dissertation note: A research project was undertaken to study the nutritive values of cotton seed meal, sesame cake and different combinations of these two on the performance of broiler chicks. The performance of chicks were studied under the headings of weight gain, feed efficiency, feed consumption dressing percentage and economics. Five starter rations containing 20,15,10,5 and 0 percent C.S.m along with 0,6,12,18 and 23.5 percent sesame cake and five finisher rations containing same proportions of C.S.m as in starter rations along with 0,5.25,10.50, 16 and 21 percent sesame cake were tried on one hundred and fifty day old broiler chicks of both sexes for period of 50 days. The starter rations were fed up to 28 days of age and remaining 22 days the finisher rations were fed. The results showed that the starter ration containing 10% C.S.m along with 12% sesame cake (Ration C) was best in promoting weight gain and feed utilization. Finisher ration containing 10% C.S.m along with 10.5% sesame cake (Ration Cl) was best in promoting weight gain, however as regard the feed efficiency, the ration containing 20% C.S.m (Ration Al) was the best. At the end of experiment dressing percentage and economic of different rations were considered. Dressing percentage value was highest of the chicks fed on ration C though statistically it was non-significant from the chicks fed on other rations. Ration E was economical as regard cost per KG live I weight.
It was concluded that the ration containing efficient proportion of both the vegetable protein supplements (10% C.S. meal and 12% Sesame Cake in starter ration and 10% C.S. meal and 10.5% sesame cake in finisher ration) was better as compared to any other ration. This was due to supplementary effect of both the vegetable protein supplements to each other deficiencies.

Publisher: 1986Dissertation note: They study was conducted on Hubbard :hicks at the Poultry Experiment Station, College of Veterinary Sciences, Lahore. The main objective of this study was to find ways and means of efficient broiler raising by using different managemental systems like floor rearing, cage rearing, transferring chicks from floor to cages and from cages to floor at different stages of rearing.
Six experimental treatments were investigated, involving 144 broiler chicks. Initially 72 chicks (treatment A) were reared in cages and 72 chicks (treatment B) on floor upto 14' days of age. On 15th day 24 birds were transferred from group A to floor (treatment C) and a similar number was shifted from group B to cages (treatment 0). on 29th day, 24 birds were again shifted to floor (treatment E) from group A. In the same way 24 birds were transferred to cages from group B(Treatment F).
The experiment continued upto 8 weeks of age. Responses measured were body weight, feed intake, FCR, Performance Index, Dressing Percentage, Breast Blisters, Mortality and Abnormalities.
The body weights at the end of 8th week were 1908,1976, 1869, 2043, 1896 and 2057g; The average feed intake was 4428, 4394, 4460, 4423, 4450 and 4521 g; the FOR was 2.318, 2.230, 2.387, 2.167, 2.350 and 2.199; The performance index was 82.312,88.810, 78.299, 94.4/4l,80.804 and 93.658; and dressing percentage was 68.89, 67.14, 67.78, 69.39, 67.75 and 68.33 for the treatment A, B, C, D, E and F respectively.
The results showed that the overall performance of caged broilers in treatments A, D, and F was comparatively better than the treatments of floor (B, C and E).
The birds that were transferred to cages (treatment D&F) gave feed conversion ratio which was significantly. (P>0.01) better than all the other groups. The caged birds gained more weight, consumed less feed, gave better FCR and produced more meat per sq. m. than the competitive groups on the floor. Among the birds reared on floor, the chicks of treatment B showed consistently better growth throughout the experiment. The figures for breast blisters and abnormalities were very similar in all treatments. The good performance of caged birds could be attributed to the better utilization of feed due to very limited movements of birds in cages.

Influence Of Various Treatments Of Rice Polishings On The Performance Of Broiler Chicks
by Abdul Majid | Prof. Dr. Nisar Ahmed Mian | Dr. Javaid Ahmed Qureshi | Dr. Muhammad.
Material type: ; Format:

Publisher: 1997Dissertation note: Increasing cost of feed ingredients and use of cereal grains in poultry feed which are also used for the human feeding, makes it imperative to look for alternative sources for feeding poultry to save grains for human consumption and reduce the cost of feed as well. Ingredients which are cheap, not utilized for human feeding and are readily available, merits consideration for poultry feeding. Rice polishing is one of such ingredient.
Rice polishings is an important by-product of rice milling industry. It is a finely powdered material obtained in polishing the rice kernels after removal of hulls and bran. It furnishes almost equivalent energy as other cereal grains and is a good source of protein and water soluble vitamins specially thiamin and niacin. It however contains certain antinutritional factors which, could be eliminated by various treatments yielding it into a useful feed ingredient for poultry feed.
Present experiment was conducted to observe the influence of rice polishings on the performance of broiler chicks after subjecting it to various treatments. Full fat rice polishings was subjected to extrusion cooking and then divided into 4 equal parts. One part was used in ration as such, second treated with 1 percent acetic acid, third treated with 1 percent calcium hydroxide and fourth treated first with acetic aid and then with calcium hydroxide. Five starter and finisher experimental rations designated as A, B, C, D, and E respectively were prepared. Ration A contained no rice polishings and was kept as control. In rations B, C, D and B treated rice polishings at 15 percent level was used substituting wheat. Starter rations were fed for 35 days and Finisher rations for 21 days to 150 Hubbard broiler chicks divided into 15 experimental units of 10 chicks each reared on floor on deep litter system. Each experimental ration was randomly allotted to 3 experimental units of chicks. Results indicated that maximum weight gain was recorded in birds fed on ration C which contained extrusion cooked rice polishings treated with 1 percent acetic acid. Lowest weight gain was recorded in birds fed on ration A (control). Second best result in weight gain was observed in birds fed on ration D which contained extrusion cooked rice polishings treated with 1 percent calcium hydroxide.
Best feed utilization per unit of gain was observed in birds fed on ration C where as poor feed conversion ratio was noted in birds fed on ration E which contained rice polishings first treated with acetic acid and then with calcium hydroxide.
Results indicated that different treatments improved the nutritional quality of rice polishings and resulted into better weight gain. Use of treated rice polishings did not show any detrimental effect on the performance of birds. Difference in feed consumed and conversion ratio towards higher side might have been due to some managemental errors or weather conditions. Extrusion cooked rice polishings treated with 1 percent acetic acid showed significantly improved growth rate and feed utilization in birds per unit of gain as compared to control and other rations containing rice polishings given other treatments.
It was concluded that various treatments improved the nutritional quality of rice polishings and it proved to be a beneficial feed ingredient for poultry feeding substituting wheat without any deleterious effect. Treatment with 1 percent acetic acid or 1 percent calcium hydroxide were equally good and potent methods to overcome the problem of antinutritional factors present in rice polishings.
