Performance of Crossbred (Landrace × Local Indian) Finisher Barrows Fed Maize or Wheat Bran Based Diets: Short Note

Bhar, R.,Pathak, N.N.,Paul, S. Asian Australasian Association of Animal Productio 2000 Animal Bioscience Vol.13 No.10

Three groups of 7, 8 and 8 barrows (22 weeks age; 35 kg body weight), reared on grower diets were fed ad libitum on three isonitrogenous finisher diets containing 50, 71 and 92% wheat bran by replacing maize grain till the attainment of about 74 kg slaughter weight. Growth pattern, average daily gain, feed intake, feed/gain ratio and carcass traits were similar in all the groups. The digestibility of DM, OM, CF, NFE total carbohydrate and energy (DE) decreased (p<0.01) with the increased level of wheat bran in the diet. However, CP digestibility was comparable among all the diet and the digestibility of EE was significantly (p<0.01) higher in grainless diet ($FD_3$). It appears that maize grain may be completely replaced with wheat bran in the diet of crossbred pigs without any adverse effect on their performance with respect to feed intake, body weight gain and carcass characteristics.

Analysis of Mean and Volatility Spillovers Using BRIC Countries, Regional and World Equity Index Returns

( Ramaprasad Bhar ),( Biljana Nikolova ) 세종대학교 경제통합연구소 (구 세종대학교 국제경제연구소) 2007 Journal of Economic Integration Vol.22 No.2

This paper analyses the degree of integration of the BRIC countries on a regional and global basis, achieved by using daily equity index level data. The paper concludes that a high degree of integration exists between the BRIC countries and their respective regions, and to a lesser extent, the rest of the world. Regional trends are found to have a much greater influence than world trends upon the stock return process of the BRIC countries. The world index returns, and most likely the US equity market returns, have a significant influence upon the variance of returns seen across Brazil, Russia and India. China is the only country where there exists a negative relationship between volatility spillover effects on a regional and global basis. This suggests existence of diversification opportunities for investment managers. Global portfolio managers can still add value from investments in these countries, however the increased levels of integration of these economies highlight the need for portfolio stock selection strategies as well as investment in specific growth areas within these economies, rather than taking a position in the country index.

Utilization of Energy and Protein in Local Indian Crossb red Gilts Fed Diets Containing Different Levels of Rice Bran

Soren, N.M.,Bhar, R.,Chhabra, A.K.,Mandal, A.B. Asian Australasian Association of Animal Productio 2004 Animal Bioscience Vol.17 No.5

Fifty four crossbred gilts of 26.38${\pm}$0.85 kg body weight and 25 weeks of age were randomly divided into three groups, having six replicates of three animals each and were assigned to one of the three dietary treatments containing corn, wheat bran and rice bran (RB) at 35, 47 and 0% in $R_1$; 17.5, 23.5 and 41% in $R_2$ and 0, 0 and 82% in $R_3$. Soybean meal and fishmeal were used as source of protein at 10 and 6%, respectively, in all the rations. Average daily CP, DCP, DE and ME intake per kg $W^{0.75}$ and body weight gains were lowest (p<0.01) in gilts fed 82% RB ($R_3$), followed by $R_2$ and R1. Utilization of protein with respect to nitrogen balance and DCP conversion efficiency did not differ (p>0.05) between the treatment groups. All the gilts were in positive nitrogen balance. However, the excretion of dietary nitrogen and energy through faeces was higher (p<0.01) in gilts fed RB. However, the DE and ME conversion efficiency were higher (p<0.01) in gilts fed RB. Therefore, it can be concluded that the digestibility of energy and protein in diets containing rice bran goes on decreasing with the increasing level of fat and fibre, but the metabolizability of the energy and protein was better in pigs fed RB in the diet.

Role of Dietary Zinc as a Nutritional Immunomodulator

Goswami, T.K.,Bhar, R.,Jadhav, S.E.,Joardar, S.N.,Ram, G.C. Asian Australasian Association of Animal Productio 2005 Animal Bioscience Vol.18 No.3

Zinc is ubiquitous in all living cells. Structural and catalytic properties of cellular enzymes are zinc dependent. Zinc deficiency leads to a variety of pathological abnormalities with immune impairment. It is an established fact that nutritional status contributes to overall immune response of individuals. Outcome of zinc deficiency on immune system is so drastic that it is difficult to conceive at the first instance. Zinc supplementation has been advocated to prevent diarrheal disease in children with poor nutritional status. The bioavailability of zinc depends upon its sources. Moreover it varies between monogastrics and ruminants. Controversy still prevails between inorganic and organic sources of zinc with respect to their superiority in bioavailability. Zinc exerts immunostimulatory effects in various laboratory and farm animals. Animals having congenital zinc deficiency diseases like A46 lethal trait usually die due to impairment of the immune system unless treated with zinc. The immune mechanism of zinc and its effect on animals and man are discussed. Zinc has been considered as extremely safe at higher therapeutic doses, but does not provide any beneficial effect but rather may cause immunosuppression. More recently, zinc has been prescribed for immunodeficient hosts, to modulate the immune system so that to a certain extent it can combat against opportunistic pathogens.

Priority-based queuing and transmission rate management using a fuzzy logic controller in WSNs

Imen Bouazzi,Jamila Bhar,Mohamed Atri 한국통신학회 2017 ICT Express Vol.3 No.2

Wireless sensor networks (WSNs) operate under challenging conditions, such as maintaining message latency and the reliability of data transmission and maximizing the battery life of sensor nodes. The aim of this study is to propose a fuzzy logic algorithm for solving these issues, which are difficult to address with traditional techniques. The idea, in this study, is to employ a fuzzy logic scheme to optimize energy consumption and minimize packet drops. We demonstrated how fuzzy logic can be used to tackle this specific communication problem with minimal computational complexity. In this context, the implementation of a fuzzy logic in the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) mechanism is achieved through filling the queue length and the traffic rate at each node. Through simulations, we show that our proposed technique has a better performance in terms of energy consumption compared to the basic implementation of CSMA/CA.

Performance of Crossbred Gilts Fed on Diets with Higher Levels of Fat and Fibre through Addition of Rice Bran

Soren, N.M.,Bhar, R.,Chhabra, A.K.,Mandal, A.B. Asian Australasian Association of Animal Productio 2003 Animal Bioscience Vol.16 No.11

Crossbred gilts (n=54) of about $26.38{\pm}0.85kg$ body weight and 25 weeks of age were randomly divided into 18 groups of 3 animals each. Three dietary treatments viz., $T_1$, $T_2$ and $T_3$ were formulated. The treatment $T_1$ containing maize grain (35%) and wheat bran (47%) along with soybean meal and fish meals served as control diet. Rice bran (RB) was selected as a single source of fat (13.02%) and fibre (17.12%), which was gradually increased in diets $T_2$ (41%) and $T_3$ (82%) replacing maize grain and wheat bran of $T_1$ at 50% and 100% in the diets $T_2$ and $T_3$, respectively. The fat and fibre levels of the diets were thus 3.46 and 5.24, 9.31and 9.69 and 11.61and 13.26% in $T_1$, $T_2$ and $T_3$, respectively. All the diets, however, contained almost similar concentration of CP (18.35${\pm}0.29%$). Each dietary treatment was offered to six replicated groups of 3 piglets in following completely randomized design and feeding was continued for 112 days during the growing phase. Growth, feed utilization, reproductive performance, nutrient utilization and different blood biochemical parameters were studied. Growth rate, feed intake and feed conversion were lower (p<0.01) in $T_3$ in comparison to $T_1$ or $T_2$. Digestibility of all the nutrients except EE was reduced significantly (p<0.01) in $T_3$. Serum glucose level decreased (p<0.01), whereas the urea and cholesterol concentration in the blood increased (p<0.01) in $T_3$. The duration of estrus of pigs fed diet containing 82% RB ($T_3$) was highly variable within the group, but all the groups showed statistically similar duration of estrous. Feed cost per unit gain was found to be comparable between control ($T_1$) and $T_2$ group. The results indicated that RB can be included up to 41% in swine diets replacing 50% of maize and wheat bran. Higher concentrations of ether extract and fibre beyond 9.31 and 9.69% in diet had detrimental effect on growth, nutrient utilization and reproductive performance.

M. Kumar,A. Kannan,R. Bhar,A. Gulati,A. Gaurav,V.K. Sharma 아세아·태평양축산학회 2017 Animal Bioscience Vol.30 No.4

Objective: An experiment was conducted to determine the nutrient intake, digestibility, microbial protein synthesis, haemato-biochemical attributes, immune response and growth performance of Gaddi kids fed with oat fodder based basal diet supplemented with either tea seed or tea seed saponin (TSS) extract. Methods: Eighteen male kids, 7.03±0.16 months of age and 19.72±0.64 kg body weight, were distributed into three groups, T0 (control), T1, and T2, consisting of 6 animals each in a completely randomized design. The kids were fed a basal diet consisting of concentrate mixture and oat fodder (50:50). Animals in group III (T2) were supplemented with TSS at 0.4% of dry matter intake (DMI), and group II (T1) were supplemented with tea seed at 2.6% of DMI to provide equivalent dose of TSS as in T2. Two metabolism trials were conducted, 1st after 21 days and 2nd after 90 days of feeding to evaluate the short term and long term effects of supplementation. Results: The tea seed (T1) or TSS (T2) supplementation did not affect DMI as well as the digestibility of dry matter, organic matter, crude protein, neutral detergent fibre, and acid detergent fibre. Nutritive value of diet and plane of nutrition were also comparable for both the periods. However, the average daily gain and feed conversion ratio (FCR) were improved (p<0.05) for T1 and T2 as compared to T0. The microbial protein supply was also higher (p<0.05) for T1 and T2 for both the periods. There was no effect of supplementation on most blood parameters. However, the triglyceride and low density lipoprotein cholesterol levels decreased (p<0.05) and high density lipoprotein-cholesterol level increased (p<0.05) in T2 as compared with T0 and T1. Supplementation also did not affect the cell mediated and humoral immune response in goats. Conclusion: Tea seed at 2.6% of DMI and TSS at 0.4% DMI can be fed to Gaddi goats to improve growth rate, FCR and microbial protein synthesis.

S.K. Chaudhary,A. B. Mandal,R.Bhar,M. Gopi,A. Kannan,S. E. Jadhav,J.J. Rokade 아세아·태평양축산학회 2019 Animal Bioscience Vol.32 No.1

Objective: This study investigated the effects of soapnut (Sapindus mukorossi) shell powder (SSP) on serum hormone level, egg quality, semen characteristics and reproductive performance of broiler breeders fed with a maize-soybean meal based diet. Methods: Ninety six female and twenty four male CARIBRO-VISHAL broiler breeders, 38-week old, were individually caged and randomly allocated to four treatment groups (24 female breeders/treatment and 6 male breeders/treatment): an un-supplemented control (T1) and three groups with 0.0176% SSP (group T2), 0.026% SSP (group T3) and 0.0528% SSP (group T4), to have supplementary saponin at 0, 50, 75, and 150 ppm, respectively, for 42 days. Results: The results indicated that serum (p<0.001) and seminal plasma (p<0.05) testosterone level, semen volume (p<0.001), mass motility (p<0.001), and live spermatozoa count (p<0.001) was increased in groups T3 and T4 compared to T2 and control groups. Compared with control group, total sperm count was increased (p<0.001) and dead spermatozoa count was decreased (p<0.001) in SSP supplemented groups. Supplementation of SSP did not affected the quality of egg lay. Compared with control group, fertility (p<0.01) and hatchability (total eggs set and fertile eggs set) (p<0.001) were significantly improved in SSP supplemented groups with the highest improvement in T3 treatment group. Embryonic death was decreased (p< 0.001) in SSP supplemented groups compared to control; lowest embryonic death was recorded in T3 treatment group. Conclusion: Thus, it was concluded that dietary supplementation of 0.026% SSP (saponin equivalent 75 ppm) improved the reproductive performance of broiler breeders.

Mehra, U.R.,Khan, M.Y.,Lal, Murari,Hasan, Q.Z.,Das, Asit,Bhar, R.,Verma, A.K.,Dass, R.S.,Singh, P. Asian Australasian Association of Animal Productio 2006 Animal Bioscience Vol.19 No.5

Sixteen adult male buffaloes (average body weight $443{\pm}14kg$) were equally distributed into four groups in an experiment to study the effect of supplementary protein sources on energy utilization efficiency in buffaloes fed a wheat straw-based diet. The animals in the control group were offered a basal diet composed of 700 g deoiled ground nut cake and ad libitum wheat straw. Animals of other groups were offered 1.8 kg of soyabean meal (SBM), linseed meal (LSM) or mustard cake (MC) along with the basal diet. Protein supplementation increased the digestibility of DM (p<0.01), OM (p<0.01) CP (p<0.01) and CF (p<0.05). Maximum CP digestibility was observed on SBM, followed by LSM and MC when compared to the control. Total DMI and DOMI was significantly (p<0.01) higher in protein supplemented groups with no differences between treatment groups. Digestible crude protein (DCP) intake and N balance were significantly (p<0.01) different between the groups; maximum response was obtained with SBM supplementation, followed by LSM and MC. Faecal energy was significantly (p<0.01) lower in SBM and LSM groups in comparison to other groups. Methane production (% DEI) was significantly (p<0.05) lower on the SBM treatment. Metabolizable energy (ME) intake increased significantly due to protein supplementation. Metabolizable energy intake (MEI) of animals in the MC group was less than LSM and SBM. Energy balance was increased significantly (p<0.01) due to protein supplementation and within supplement variation was also significant with maximum balance in SBM followed by LSM and MC groups. Protein supplementation significantly (p<0.05) increased the digestibility and metabolizability of energy from whole ration. Metabolizable energy (ME) content (Mcal/kg DM) of SBM, LSM and MC was 4.49, 3.56 and 2.56, respectively. It was concluded that protein supplementation of wheat straw increased intake, digestibility and metabolizability of energy and maximum response could be obtained when soybean meal was used as a supplement.
