ArticleItem Open Access Assessment of Losses in Sheep and Goat During Pre-Slaughter Transportation(New Delhi Publishers, 2018-06) Vignesh, P; Babu, Narendra R; Abraham, Robinson J.J.; Gnanaraj, Tensingh; Govind, V; Rao, Appa V; TANUVASA study was conducted to estimate the different types of losses in sheep and goat during transport from shandy to slaughter house both in summer and winter seasons. Pre-slaughter losses were documented and different practices adapted in two different types of short (about 20 kms) and long (about 150 kms) distance transportation in the present study. A weight loss of 0.95 and 0.98 per cent was recorded in winter and summer seasons during short distance. A weight loss of 3.02 and 3.18 per cent was recorded in winter and summer seasons respectively during long distance transport of 150km which were lesser than earlier findings. There is no significant difference in total injuries, per cent actual weight loss in live animals, dead animals on arrival, weight loss due to excreta, total weight loss during winter and summer seasons in both types of transport. Some other observations also made like time of transit, average feed withdrawal time and average age of animals. Further, study revealed no significant difference in temperature and relative humidity observed in shandies and in transport vehicle between winter and summer seasons which might be due to transportation of animals in early morning hours in both the seasons. The lower losses in weight and mortality rate observed in this study may be correlated to the fact that the temperature and relative humidity of the transport environment were within the comfort zone of the animals.ArticleItem Open Access Economic loss due to live weight shrinkage and mortality during broiler transport in summer and winter season in Chennai city(Akinik Publications, 2018-01) Ramakrishnan, C; Babu, Narendra R; Rao, Appa V; Abraham, Robinson JJ; Gnanaraj, Tensingh P; Ruban, Wilfred S; Bhaskar, Kanchi; TANUVASThe aim of the study is to determine the economic impact of live weight losses and mortality due to transport of broilers from farm to wholesale/retail outlets in summer and winter season in Chennai city. Data concerning 24 visits from different farms of integration to wholesale/retail outlet in winter and summer season were collected for the purpose of study. Data were classified into two seasons were winter and summer in that the total number of chickens transported in winter and summer season were 2225.83 ± 82.75, 2246.37 ± 98.88 the live weight shrinkage was 2.36%, 3.01% and mortality percentage were 0.43%, 0.53% and average weight loss per bird (gram) is 55.42 ± 5.65, 70.98 ± 6.01 respectively. The results of the study shows that the average marketing age of transported chickens are 39 days old, average density of the broilers were 2236.25 per truck. The results revealed no significant difference in loss of weight, dead on arrival, types of injuries, tissue shrinkage and duration of transport between summer and winter season. Wetting of birds was practiced and the frequency was higher during summer compared to winter season.ArticleItem Open Access Effect of calcium propionate and coated sodium butyrate as an alternative to antibiotic growth promoters on the serum profile of commercial broiler chicken(AkiNik Publications, 2018-01) Naveenkumar, S; Karthikeyan, N; Babu, Narendra R; Veeramani, S; Krishnani, Sivarama; Srinivasan, G; TANUVASAn experiment was conducted with 240 day old commercial broiler chicks to evaluate the effectiveness of replacing antibiotic growth promoters with organic acid salts on the serum profile. Treatment diets were supplemented with lincomycin HCl (4.4 ppm), bacitracin methylene disalicylate (BMD; 50 ppm), each two levels (ppm) of calcium propionate (1000, 2000) and coated sodium butyrate (500, 1000) either alone or in combination (1000+500) with control. The results showed that there was no significant difference in kidney & liver function tests, serum protein and mineral profile among the treatment groups. And in case of lipid profile OAs supplementation showed significantly beneficial impact. The levels of serum profile parameters were in normal range, that suggesting good nutritional status of the birds in all the treatment groups. Salts of organic acids (OAs) could be safely supplemented as an alternative to antibiotic growth promoters (AGPs) in the commercial broiler diet to lower the risk of residues in the meat and to avoid the antibiotic resistance (if any) to the consumers without impair the serum profile and birds health.
