A twelve week feeding trial was conducted to investigate the effect of air-dried mucuna (Mucuna pruriens) leaf meal (MLM) in the diets of grower rabbit bucks. Mucuna leaf meal was included at 0%, 5%, 10%, 15% and 20% for T1, T2, T3, T4 and T5 respectively. Thirty grower rabbits bucks were assigned to five experimental dietary treatments denoted T1, T2, T3, T4 and T5 respectively in a completely Randomized Design (CRD). Each treatment had six rabbits with each serving as a replicate. Results of performance showed that there were no significant differences in final body weight, daily weight gain, daily feed and protein intake. Protein efficiency ratio and feed conversion ratio were significantly higher at T1. Nutrient digestibility by rabbit indicates significant different (p<0.05) in ether extract (EE), crude fibre (CF), and crude protein (CP). EE and CF were significantly higher at T4, and CP was highest at T1. There was no significant difference (P>0.05) in NFE across the treatments. There was also no significant difference (P>0.05) for cost per kg gain. Cost of feed consumed, total cost and percentage feed cost were significantly higher (P<0.05) at T1, T2, and T3. Percentage drug cost was significantly better (P<0.05) at T4 and T5, percentage cage cost and animal were statistically depressed (P<0.05) at T1, T2 and T3 and highest at T5. It was concluded that mucuna (Mucuna pruriens) leaf meal has potentials as a valuable unconventional leguminous feedstuff. The use of Mucuna pruriens leaf meal in the diets of rabbit bucks promoted growth best at 5% and thus carcass yield. Rabbit farmer can incorporate Mucuna pruriens leaf meal at 5% for growth performance.

Aims: The effects of high fibre diet fed to broilers chicken on growth, carcass performance sensory evaluation, primal cuts and meat characteristics were carried out in a eight weeks feeding trials.

Methodology: A total of two hundred and forty, day old broiler chicks of Arbor Acer breed obtained from a commercial hatchery was used for the trial. An average (33±0.12 g body weight) were weighted individually and randomly divided into three (3) Treatment with ten replicate per treatment and eight birds per replicate using a completely randomized design. The diet contained T1= 8.70% fibre; T2= 13.10% with enzyme and T3= 13.10% fibre without enzyme. Parameters measured are daily feed consumption, weekly body weights, weight gain and feed conversion ratio were properly recorded. Carcass performance parameters were measured and recorded for both the external and internal organs, primal cuts, sensory evaluation, cooking loss and yield using a standard procedure. Data were analysed using descriptive statistic and ANOVA at α0.05.

Results: There were no significant difference (P<0.05) for weight gain and feed conversion ratio while Treatment 3 had the highest daily feed consumption and weekly body weights with least daily feed consumption, and weekly body weights in Treatment 1. The result shows that there was no differs in carcass performance, external organs weight as well as internal organs weight. There was no significant difference (P<0.05) observed in the primal cuts and sensory evaluation. The cooking loss was significantly higher (P>0.05) in Treatment 1 (control with 8.7% fibre) 33.36% with least cooking loss in Treatment 3 containing 13.10% (21.54%). Treatment 3 had the highest cooking yield (78.46%) compared to other treatment.

Conclusion: Broiler chicken can be fed with 13.10% fibre diet without enzyme without any adverse effect on the growth, carcass performance, enhances better cooking yield and lower cooking loss.

Eight weeks feeding trails were conducted with 120 broiler chickens at poultry production unit of the Department of Animal Science, Usmanu Danfodiyo University Sokoto. The aim is to determine performance characteristics of broilers fed termite supplemented diet (Macrotermes bellicosus) at starter and finisher stage. A commercial diet was compared with two other diets; fishmeal diet and termite supplemented diet. Each of the three treatments was replicated four times, with ten chicks per replicate in a Complete Randomized Design (CRD). Broilers were fed regularly throughout the period of the experiment. Results of Carcass evaluation showed significant (P˂0.05) difference in weight of broiler parts like; breast, drum stick and liver, but there was no significant (P˃0.05) difference in back, thigh, wings and gizzard in all treatment diets. Other parts; feet, head, and spleen showed significant (P˂0.05) difference. But neck, heart, lungs, intestine and crop shows no significant (P˃0.05) difference in their weights. Proximate analysis showed no significant (P˃0.05) difference in nutrient composition in all the treatment diets, only ash showed significant (P˂0.05) difference in fishmeal. Mineral composition showed significant (P˂0.05) difference in almost all treatment diets except in phosphorus, copper and zinc. It was concluded that termite supplemented diet can successfully and economically replace fishmeal as protein source in the diets of broilers without deleterious effect on their health and carcass quality.

Asian Journal of Research in Animal and Veterinary Sciences, Page 1-11

The main objectives of the study were to determine the consumers’ awareness regarding the effect of antibiotics used in animal feed on human health and to explore relationship between the selected characteristics of the respondent consumers and their awareness. The study was conducted at Mohammad Nagar residential area under Batiaghata upazila of Khulna district and Nirala residential area of Khulna City Corporation, Khulna, Bangladesh following descriptive and diagnostic type of research design. Forty respondents from each of the residential areas were interviewed as the sample of the study and data were collected through personal interview method using an interview schedule by the researcher between January–February, 2019. Most (80%) of the respondents were highly aware while only one fifth (20%) of the respondents had medium awareness about the effect of antibiotics used in animal feed on human health. Consumers were highly aware that resistance is grown in pathogenic organisms causing diseases in human body against antibiotics that were used in patient treatment; thus, resulting in treatment failure. However, consumers were less aware about allergic reaction and painful rash, which are possible with many antibiotics. The mean awareness score of the consumers residing at Nirala was higher than that of Mohammad Nagar residential area but it did not differ significantly. This might be due to proximity of the two residential areas. Among ten selected characteristics of the respondents; education, family education, annual family income, exposure to communication media, nutritional knowledge, animal protein consumption behavior and attitude showed positive significant relationship with their awareness regarding the effect of antibiotic used in animal feed on human health. Consumers in the study area are concerned about the effect of antibiotics used in animal feed on human health.

Asian Journal of Research in Animal and Veterinary Sciences, Page 1-8

The study was carried out to estimate the effect of year of calving on reproductive performance traits of Holstein Friesian cows that calved between 2006 – 2017. Five hundred and thirteen (513) calving records obtained from Integrated Dairy Farm Vom were collated for the study. Data was analyzed using the general linear models of SAS 2001 (version 8.0). Results revealed that the overall mean of Age at First Calving (AFC), Calving Internal (CI) and Days Open (DO) were 30.36±0.23 months, 379.70±13.34 days and 93.67± 9.74 days respectively.  All the reproductive traits in the study have significant effect (P<0.05) on year of birth of dam. The first, third, fourth and fifth calving interval has significant effect (P<0.05) on year of birth while the second and sixth calving interval had no significant influence (P>0.05) on year of birth. The observed reproductive performance of Holstein Friesian cattle under Vom condition was generally commendable. This may be attributed to improved management practices (such as high quality feed), maternal gene effect, accurate heat detection, timely insemination and adaptation of Holstein Friesian breed to the climatic condition of the study area (due to lower temperature).
