Two hundred and forty unsexedd broiler birds of Anak breeds af one week of age were used to study the utilization of potash treated shrimp waste meal (SWM) in broiler diets fed as mash or pellet form in a 2x2x2 factorial experiment. The birds used were randomly allotted to eight treatment groups with three replications. SWM used was either polash treated or untreated, plate willed or hammer milled. Growth performance, muirient utilization, and carcass characteristics were measured. Potash treatment of SWM led to a significant increase (P<0.05) in final live weight of the birds at starter phase, but such effear was not noticed at finisher phase. Starter broilers fed mash diets had a significantly (P<0.05) higher mean final live weight (579.08), than those seed pellet diet (493.12). but the difference at fisher phase was not significant. The processing methods did nor significantly (P>0.05) improve the performance of the birds or finisher phase, though slight improvement was noticed in bird's fed pelleted diets. The processing methods did not significantly (P>0.05) influence the protein retention, ash and ether extract digestibility at starter phase. Crude fibre digestibility was significantly (P<0.05) improved by plate milling and pelleting of the diets, and the interactions of the processing methods. Dry marier digestibility and crude protein retention of finisher broilers were significantly (P<0.05) improved by the dietary treatments. It was concluded that the treatments employed yielded no commendable performance in broilers. Pelleting of SWM based diets slightly improved iis utilization by finishing broiler chickens.

Effect of toasted jackfruit (Artocarpus heterophyllus) seed meal (TJSM) on performance of 120 2 weeks old broiler chickens was investigated. The birds were divided into four dietary treatments having 3 replicates and 10 birds per replicate in a completely randomized design. Diet one (T) was soybean based while toasted JFSM meal was added to diets 2 (T), 3 (T) 1 2 3 and 4 (T) at 5, 10 and 15% levels of inclusion, respectively. Growth performance was 4 generally depressed with increased inclusion of toasted JFSM in the diets. Feed conversion ratio of birds fed T and T were the same and significantly better (P>0.05) than those of the 1 2 remaining treatment groups. Birds fed T had significantly higher values of live weight, 1 dressed weight and dressing percentage followed by birds fed T. The prime cut parts were 2 similar in all the treatment groups. Organ proportions showed no significant differences across the treatment groups except the spleen. Cost per kg feed decreased with increased inclusion of TJSM. The cost of feed consumed was higher (P>0.05) in T (531.29) but 1 decreased with increased inclusion of TJSM. The cost per kg weight gain, cost of production and revenue were similar across the treatment groups with birds fed T significantly higher 1 (P>0.05) than the remaining treatment groups. The gross margin obtained for birds fed T 1 and T are comparable and higher than other treatment groups. From the foregoing TJFSM is 2 a potential feed resource and could be included in the diet of broiler chickens up to 5% inclusion level.

Dietary Treatments

The influence of insect protein origins on broiler chicken meat parameters were studied using 135 day old Arbor acre birds subjected to three dietary treatments: Diet A comprised of a standard feed of the brand name ‘vital feed’ containing fishmeal as the major protein source (control), while Diet B and Diet C contained insect meal from African palm weevil larvae (Rhynchophorus phoenicis), respectively, winged termite (Macrotermes bellicosus) as replacement for fishmeal. Forty five broiler chicks were randomly assigned to each of the dietary treatments at the rate of fifteen chicks per replicate making three replicates per treatment in a completely randomised design. The experiment lasted for eight weeks. During this period, the birds were housed in similar cages and subjected to similar husbandry and sanitation practices, such that the only source of variation was the dietary treatments. After eight weeks of the experiment, carcass quality and organ weight measurements were analysed using appropriate statistical analysis. The result obtained showed that the broiler chickens fed insect meals performed significantly (P<0.05) better in terms of live weight gain (2,200.85±64.23 g and 2,046±58.40 g for Diet B and Diet C) compared to control. Carcass quality relating to defeathered weight and eviscerated weight also followed a similar trend with Diet B (2,187.74±62.72 g and 1,788.93±70.70 g), Diet C (2,015.83±74.62 g and 1,466.97±100.05 g), and Diet A (control; 1,526.47±47.40 g and 1,240.30±64.53 g). The records of cut-up parts and organ weight measurements were also significantly different (P<0.05) for the birds on insect meal (Diet B and Diet C) than those on fishmeal based diet (Diet A). The result showed that insect meal can effectively serve as a major source of protein in poultry feed formulation.

The study was undertaken to investigate the effects of concentrate supplementation with different protein levels on intake, digestibility and growth performance of Red Chittagong (RC) heifers fed urea molasses straw (UMS) based diet. Twelve RC heifers having average live weight of 124.83±43.15 kg and aged between 8 to 14 months were selected for 90 days feeding trial. Animals were divided into four groups having three animals in each and were randomly assigned to four dietary treatments in a Randomized Block Design (RBD). The experimental diets were formulated using urea molasses straw (UMS), German grass (Echinochloa grousgalli) with or without concentrate mix (having different levels of protein). All the animals received UMS ad libitum and German grass at the rate of 20% of total DM intake. In addition to UMS and German grass of control diet T0, animals on diets T1, T2 and T3 were supplied with concentrate mixture at the rate of 10% of DM intake containing 15, 20 and 25% CP, respectively. Average daily DM intake was 2.65, 3.06, 2.62 and 2.86 kg/100 kg LW for diets T0, T1, T2 and T3, respectively and the difference was non significant (P>0.05). The digestibility of DM, CP, EE, NFE and digestible nutrients (DCP, DEE and DNFE) for diets T1, T2 and T3 was significantly higher than those for diet T0. The daily average liveweight gain of RC heifers fed diets T0, T1, T2 and T3 were 100, 275, 333 and 291 g respectively (P<0.01). Concentrate mixture having 20% crude protein may be supplemented at the rate of 10% of DM intake per day for optimum growth of Red Chittagong heifers.

This study sought to assess the effect of dietary crude fibre – energy relationships onthe blood profile of unsexed Obamarshal strain of broiler chickens fed different levels of dietary crude fibre (CF) each at three levels of metabolisable energy (ME) in multi-fibre source-based diets from day-old to 56 days of age. Results indicated that neither CF nor ME and their interaction had significant effect on hematological indices measured at 50 days of age. The values of hematological indices obtained for the treatment groups fell within the standard values for normal chickens. Except for the blood cholesterol, there was no significant effect of varying levels of CF or ME on other serum metabolites and likewise their interaction effect. While increasing CF level tended to reduce significantly (P<0.05) blood cholesterol, incremental levels of ME tended to increase (P<0.05) blood cholesterol and also their interaction effects. The values of serum cholesterol in the birds ranged from 106 mg/dl for diet B to 181 mg/dl for diet D, which were within the range for normal chicken. Conclusively, the findings showed that blood profile was not adversely affected even at 12% CF and 3000 ME (Kcal/kg) diet.

Control Study

Infectious bovine keratoconjunctivitis (IBK) caused by Moraxella bovis is commonly seen in the summer months spread by face flies. This trial investigated the difference in incidence of IBK cases from natural exposure between two groups of animals, one treated with Cypermethrin pour-on preparation (PON, n = 98) and one with Cypermethrin impregnated ear tags (TAG, n = 99). Daily Live Weight Gain (DLWG) difference was investigated between animals with cases and those without and between treatment groups. A randomised positive control study, enrolled 197 animals split into two treatment groups. Cases of IBK and DLWG were recorded over the grazing season (April–November 2018). Fifty-four cases of IBK were recorded. There was no association between the two treatment groups (p = 0.362) and case status. Breed and under 12 months old were significant factors for having a case; (OR 2.3, p = 0.014 and OR 3.5, p < 0.001 respectively). There was no difference in DLWG between animals that had a case and animals that had not (p = 0.739) or between the two treatment groups (p = 0.215). Based on our results, there is no significant difference between PON or TAG preparations in the prevention of IBK. Younger animals and white-faced breeds are significantly more likely to suffer with IBK.

1. The four systems of rearing dairy heifer calves, described in Part 1 of this series are now studied for their effect on absolute and relative growth rates to maturity.2. Data on live-weights and measurements and the percentages of mature size attained by these at 44, 80, 104, 132, 182, 260 and 312 weeks of age are tabulated.3. In all groups the measurement to reach maturity earliest was circumference of metacarpus followed in order by length of back, height at withers and width of hooks.4. By 6 years of age all groups had attained approximately the same body size. Maturity in the LL group in terms of four skeletal measurements was delayed by only 9 months, and in the case of HL and LH animals by 5 and 4 months respectively.5. All groups showed the same general pattern of relative growth but the effect of restricted feeding was to increase at the younger ages the difference i n percentage of mature size between early and late maturing measurements. After 44 weeks of age the rate of growth was most rapid in those measurements which were furthest from maturity then.6. The rate of tissue deposition was markedly increased in high plane animals during early pregnancy compared with low plane. Evidence is presented to show that much of this was lost during lactation.7. At first oestrus, animals in all four treatment groups had reached the same percentage of mature size for each body dimension (except for length of back in the LL group).8. From data on 5 animals it is shown that although growth in height at withers and length of back ceased by 6 years of age there was slow but continuous growth in live-weight, middle and heart girths and width of hooks to 9 years of age.

trial to determine the bactericidal effect of lemon juice on feed bacterial load and its dietary effect on growth and apparent nutrient digestibility of broiler chickens. There were five dietary treatments (T1 – T5) containing lemon juice 0.0, 10, 15, 20 and 25mL/kg diet, respectively. Each treatment was replicated three times with 10 birds each, giving 30 birds per treatment. The experiment was arranged in completely randomized design (CRD). Starter diet was fed ad libitum for 3 weeks and finisher diet for 4 weeks. Water was given also ad libitum throughout the experimental period. Citric and ascorbic acids content of the lime and the pH were determined. At the end of the experiment, results showed that the juice contained ascorbic acid (2.76), citric acid (4.23) with low pH (3.87) and exhibited antibacterial action. Above 10mL/kg inclusion level, apparent nutrient digestibility of crude protein, ether extract, crude fibre, ash and energy utilization were improved. At the starter phase 20 and 25mL/kg improved final live weight and protein efficiency ratio. Final live weight was improved by 15, 20 and 25mL/kg at the finisher phase. In conclusion, addition of 15mL/kg lemon juice in broiler diets could be a good practice and is recommended.

This study, aimed to determine the effects of different light regimen and day/night feeding on some performance criteria of 1104 broiler chickens during summer season. At the beginning of second week they were separated according to their sexes, and experiment had 2 × 6 replications. The 1st group, as control, received continuous lighting (daylight + lightening during night) and fed ad-libitum. The 2nd group was treated with continuous lighting too, but they had no access to feed between10:00 and 16:00 o’clock during the last three weeks. The 3rd group was also exposed to continuous lighting but had no access to feed between10:00 am and 16:00 pm. Fourth group received continuous lighting but had no access to feed between 24:00 pm and 06:00 am. Fifth group received continuous lighting, but they were not fed between 24:00 pm and 06:00 am during the last three weeks of experimental process. Sixth group had no access to feed box during 24:00 pm and 06:00 am, when they had not been exposed to light as well. There were no notable differences in live weight gain of male and female birds for all treatment groups, and similarly differences among feed consumption and feed conversion ratios were not remarkable statistically regardless of the sexes of chickens. There were significant differences in hot-cold carcass yields of the 3rd and 6th treatment groups for male birds and 6th treatment group for female birds. The differences for carcass weights of male birds were statistically significant and 3rd and 6th treatments groups were tend to be relatively higher than the other treatment groups. The differences among treatment groups for carcass weights of female birds, however, were not significant and similarly the effects of the treatments on the mortality rate was found to be in significant for same birds. Lightning (24h) and feeding ad - libitum affected the performance of the birds adversely, whilst restricted feeding and lightning process reduced the yield-loss the animals during the summer season.

Three hundred 21-day-old broiler chicks were reared using a 3 x 3 factorial model in a completely randomized design with 10 treatment groups having 3 replicates of 10 birds each. The birds were raised on a commercial starter diet at the starter phase before being allotted into dietary groups in a 21-d feeding trial at the finisher phase. The interaction between treatment and varying inclusion levels of processed-fermented Jatropha curcas (L) kernel meals (JKM) on the performance of broiler chicks was investigated. Jatropha curcas kernels were subjected to three different processing methods, namely: raw defatted fermented meal (RDFM), cooked defatted fermented meal (CDFM) and lye treated defatted fermented meal (LDFM). Each meal was included at varying inclusion levels of 2.5%, 5.0% and 7.5% such that diet 1 (control) contained 0% JKM while diets 2, 3, 4 contained 2.5%, 5.0% and 7.5% RDFM, diets 5, 6, and 7 contained 2.5%, 5.0% and 7.5% CDFM and diets 8, 9, 10 contained 2.5%, 5.0% and 7.5% LDFM. Feeding differently processed-fermented JKM to these broilers did not (p>0.05) compromise the feed conversion ratio. The results indicated an improvement (p<0.05) in the weight gain of broiler chicks fed CDFM and LDFM at 2.5 and 5.0% inclusion levels respectively. There were significantly (P<0.05) elevated levels of alkaline phosphatase and creatinine in their blood serum. The kidney, lungs and proventriculus of birds fed CDFM showed significant differences (p<0.05) among the treatments. Therefore, finisher broilers could tolerate up to 5.0% inclusion level of LDFM.

This experiment was designed to determine the meat quality and lipid profile of broiler chickens fed diets containing turmeric (Curcuma longa) powder (Tur) and cayenne pepper (Capsicum frutescens) powder (Cay) as antioxidants. Two hundred and forty three (two-week old) Abor Acre broiler chicks were randomly allotted to nine treatment groups of 27 birds each, consisting of three replicates of nine birds each in a completely randomised design. Three levels of Tur (0, 2 and 4 g/kg) and three levels of Cay (0, 1 and 2 g/kg) were used to provide nine dietary treatments.  Meat quality indices such as cook and refrigerated losses, water absorptive power, etc were measured and determined at the 8th week. Broiler Chickens fed the basal diet had highest meat dry matter, protein content and least (p<0.05) meat pH, cook and refrigeration loss values. Meat triglyceride and meat malondialdehyde value was best (p<0.05) in treatments fed dietary 2 g/kg Cay, while chickens fed 2 g/kg Cay, 2 g/kg Tur + 1 g/kg Cay and 2 g/kg Tur + 2 g/kg Cay had better meat lipoprotein values. For meat sensory characteristic, meat flavour of broiler chickens fed diets containing 2 and 4 g/kg dietary Tur, were  moderately liked while overall flavour was best (p<0.05) in groups fed the basal diet with no dietary additive. It was evident in the study that the dietary inclusions of the test ingredients limited lipid oxidation, thus improved storage duration and meat flavor.
