ArticleItem Open Access Effect of Dietary Protein and Fibre on the Hematological, Biochemical and Thyroid Profile of the Obese Dogs(Veterinary Association, 2022-05) Abinaya, A.; Karu, Pasupathi; Karunakaran, R.; Joseph, Cecilia; Chandirasekaran, V.; TANUVAS24 Labrador obese dogs were selected based on their body condition score and body weight. The animals were randomly divided into four treatment groups with six animals in each treatment. T1 was kept as control and fed with normal diet (AAFCO, 2014) andT2, T3, T4 were fed with high-protein high fibre, high-protein medium-fibre and control diet supplemented with choline chloride, respectively, for a trial period of four months. The blood samples were collected and analysed for the hematological, biochemical and thyroid profile of these obese dogs. No significant difference (p>0.05) found in the hematological and biochemical parameters of the dogs except in the concentration of glucose and blood urea nitrogen. The values of glucose were lowest in T2with 75.83 ± 2.66 mg/dl and highest in control with 92.16±3.55mg/dl. Also the thyroid profile was not altered by the weight-loss in obese dogs.ThesisItem Open Access EFFECT OF DIETARY PROTEIN, FIBRE AND LIPOTROPIC FACTOR ON THE MANAGEMENT OF CANINE OBESITY(2018) Abinaya, A; Karu, Pasupathi; Karunakaran, R; Joseph, Cecilia; Chandirasekaran, V; TANUVASA study was carried out to formulate different therapeutic diets for the management of canine obesity and to evaluate the effect of prepared therapeutic diets in obese dogs. Four different dietary formulations namely, control diet (T1) (based on AAFCO, 2014), high protein high fibre diet (T2), high protein medium fibre diet (T3) and the control diet supplemented with choline chloride (T4) were prepared by extrusion. The percentage of crude protein and crude fibre of T1, T2, T3 and T4 diet were 15.74 ± 0.04, 21.90 ± 0.18, 21.73 ± 0.25and 15.72 ± 0.04 and 4.09 ± 0.06, 11.28 ± 0.16, 8.23 ± 0.17 and 3.99 ± 0.12, respectively.ArticleItem Open Access Effect of In Ovo Supplementation of Amino Acids and Nanoselenium on Small Intestine Histomorphometry(Indian Veterinary Association, 2017-11) Chandiranathan, T.; Karu, Pasupathi; Valli, C.; Omprakash, A.V.; TANUVASSix hundred and twenty five Vencobb-400 fertile eggs were randomly divided into five treatment groups, each with five replicates to study the effect of in ovo supplementation of amino acids combination with nano form of selenium on small intestine histomorphometry. The treatments T1,T2,T3,T4 and T5 were injected with normal saline (0.5 ml), amino acids (Glycine-3.22 mg + Proline-3.24 mg), amino acids (Lysine-5.16 mg + Arginine-5.04 mg + Glutamine-12.10 mg), amino acids in T2 with nano form of selenium (0.3 μg) and amino acids in T3 with nano form of selenium (0.3 μg), respectively in ovo on 18th day of incubation. Intestinal histomorphology revealed that supplementation of amino acids in combination with nano form of selenium influenced villus length and width of duodenum, jejenum and ileum. Based It was concluded that in ovo supplementation of amino acids and nano selenium improves (P<0.01) small intestinal villus length and duodenal villus width in broilers in comparison to control treatment.ArticleItem Open Access Effect of Macroalgae Supplementation on Growth Performance of Japanese Quails(Excellent Publishers, 2018-02) Karu, Pasupathi; Selvan, ST; Gopi, H; Manobhavan, M; TANUVASAn experiment was conducted to assess the growth performance of quails on supplementation of seaweeds. 600 numbers of day old quail chicks were randomly divided into four groups with five replicates and 25 chicks in each replicate. Seaweeds viz., Chaetomorpha antennina, Sargassum wightii and Gracilaria corticata were collected from Gulf of Mannar region and was dried and included in the ration @ 3 % level and treated as group - 2, 3 and 4, respectively. Quail on normal ration was kept as control (Group -1). The trial was conducted for six weeks period. Daily feed intake and weekly changes in body weight were recorded. Analyzing the data revealed that there is no significant differences in body weight and FCR @ 3 % level of seaweeds supplementation compared to control group.ArticleItem Open Access Evaluation of in vitro digestibility of high protein and fibre diet in obese dogs(2022-04) Abinaya, A; Karu, Pasupathi; Karunakaran, R; Joseph, Cecilia; TANUVASFour different therapeutic diets viz., T1 (control - 15.7% CP and 4.09% CF) T2, T3 and T4 of high protein (21.90% CP) high fibre (11.28% CF), high protein (21.73% CP) medium fibre (8.23% CF), and control diet supplemented with choline chloride (15.72% CP and 3.99% CF) were prepared and subjected to in vitro enzymatic hydrolysis and in vitro fermentation characteristics, in which in vitro dry matter digestibility and gas production were estimated. The dry matter digestibility was significantly higher (p<0.05) in T1 (84.30 ± 0.97) and T4 (84.80 ± 0.41). Gas production were significantly higher in T2 (16.82 ± 0.88 ml/g DM) followed by T3 (10.76 ± 0.64) was observed. The overall DM digestibility of all the diets was more than 75%, which showed overall higher digestibility of all nutrients in the prepared therapeutic diets.ArticleItem Open Access Growth performance of rabbits on Mangifera indica tree fodder(2020) Karu, Pasupathi; Gopu, P; Balasubramanyam, D; TANUVASA research trial was conducted to assess the growth performance of rabbits on Mangifera indica tree leaves partially (25 %) replacing the Desmanthus virgatus green fodder. 20 New Zealand White rabbits of 7 weeks old were randomly divided into two groups with 10 rabbits in each. Group – I rabbits were kept as control, fed with concentrate (70 % DMI) and Desmanthus virgatus (30% DMI) and group-II animals were fed with concentrate (70 % DMI) and 22.5% Desmanthus virgatus green fodder and 7.5 % Mangifera indica tree fodder. The trial was conducted for three months. The parameters studied are daily feed intake, bi-weekly weight gain and FCR. The result revealed that there is no significant difference in bodyweight gain between the treatment groups. Hence, Mangifera indica tree fodder can be safely included without affecting growth performance in rabbits up to 7.5 % of the dry matter intake.ThesisItem Open Access IN OVO SUPPLEMENTATION OF AMINO ACIDS AND NANO SELENIUM ON COMMERCIAL BROILER CHICKEN PERFORMANCE(TANUVAS, 2016) Chandiranathan, T; Karu, Pasupathi; Valli, C; Omprakash, AV; TANUVASA research was carried out in two phases to study the effect of in ova supplementation of amino acids in combination with nano form of selenium on hatchability, post hatch performance, small intestine histomorphology and immune status of chicks. In phase-l of the study, stable nano form of selenium was prepared by wet chemical method (water solution phase method) with a mean yield of 62.07 ± 2.52 per cent. The size of the nano form of selenium obtained was 79.43 ± 1.32 nm and zeta potential of -27.03 ± 0.28 mV. In phase-ll of the study, six hundred and twenty five Vencobb-400 fertile eggs were purchased and randomly divided into five treatment groups.ArticleItem Open Access Influence of Estrus Synchronization Protocols on Serum Protein during Reproductive Cycle in Kilakarsal Ewes(2020-06) Sundara Vinayaki, M; Gomathi, S; Logaathasamy, K; Karu, Pasupathi; TANUVASA research work was undertaken to induce estrus synchronization in Kilakarsal ewes, using chitosan nanoconjugated GnRH and to assess its efficacy and economic feasibility under semi intensive farming conditions by comparing the same with various drug protocols. Ewes in the control were not given any treatment. The group I ewes were treated with CIDR alone. The group II ewes were treated with CIDR and GnRH. The group III ewes were treated with CIDR and PGF2α. The group IV ewes were treated with CIDR, PGF2α and GnRH. The group V ewes were treated with CIDR and Nanoconjugated GnRH. The group VI ewes were treated with CIDR, PGF2α and Nanoconjugated GnRH. The serum total protein level during the off season on the day of CIDR insertion, CIDR removal, day of estrum, day of mating and on the 70th day of pregnancy in control and different treatment groups ranged from 7.23±0.17 to 7.45±0.11, 6.71±0.10 to 7.06±0.11, 8.00±0.22 to 8.88±0.14, 7.29±0.19 to 7.55±0.11 and 6.53±0.26 to 6.88±0.22 g/dL, respectively. The values observed in groups II and III were significantly higher (P<0.05) when compared with that of the other groups on the day of CIDR removal. On the day of estrum the serum protein values were found to be significantly (P<0.05) lowest in control group when compared with that of the other groups on the same day sampling. It was concluded that the novel protocol of combining CIDR with or without PGF2α and nanoconjugated GnRH was very safe and effective to induce intense estrus synchronization, achieve better % of reproductive performance and may be adopted in the field to increase sheep production.ArticleItem Open Access Influence of Organic Manures on Fodder Yield and Nutrient Composition of Dolichus trilobus in Punica granatum Based Hortipastoral System(2020) Mynavathi, V.S.; Karu, Pasupathi; Ramachandran, M.; Valli, C.; Balasubramanyam, D.; TANUVASLivestock play a significant role in countries economy. Livestock production is mainly limited by insufficient fodder and poor nutrition. Effective utilization of organic manures plays an effective role in proper nutrition and increasing the green fodder production of fodder crops. In this context an experiment was conducted to study the effect of different organic manures on the green fodder yield of Dolichus trilobus in Punica granatum based hortipasture system with different organic manure practice. Pillipesara (Dolichus trilobus) was grown on a degraded wasteland under Punica granatum based hortipasture system in North Eastern Agroclimatic zone of Tamil Nadu during 2017. The experiment was laid out in Randomized Complete Block Design (RCBD) with four treatments replicated thrice. Treatments consisted of three different manures on N equivalent basis viz., cattle manure, goat manure, swine manure and a control (without manure). Manures were incorporated as per the treatment as basal application. Fodder was harvested on 60th day at different places and fresh weight was recorded and Dry matter production (DMP) was estimated. Harvested plant material was weighed, dried and the ground subsamples were taken for analysis of crude protein (CP) and crude fibre (CF) as per AOAC, (2000) method. The growth performance of Dolichus trilobus revealed that application of 100% cattle manure on Nitrogen equivalent basis performed better in terms of fresh fodder yield (17.58 MT/ha) and dry fodder yield (3.52 MT/ha) under Punica granatum based hortipasture system. Higher crude protein of 16.52 % and crude fibre content of 21.24 % was observed with the application of 100% cattle manure on Nitrogen equivalent basis treatment. Hence, application of 100 % Cattle manure on N equivalent basis can be effectively utilised as a source of nutrient for the crop to enhance the nutrient composition of the fodder crop grown in the system.ArticleItem Open Access Integrated Fish Farming (Ostrich And Cattle Cum Fish) in an Organized Livestock Farm in Tamil Nadu(TANUVAS, Chennai, 2021-05) Chandrasekar, T.; Sivakumar, K.; Gopu, P.; Karu, Pasupathi; Senthilkumar, K.; Balasubramanyam, D.; TANUVASIntegrated Farming System (IFS) is an efficient way of recycling farm waste or farm by-products. In present study the fishes (Catla, Common carp, Grass carp, Rohu and Silver carp) were cultivated through ostrich feed wastages and cattle manure in six month period. The average fish survival of 86% was observed and it was varied from 84% to 88%. The total weight of fishes harvested was 50.95 kg, 43.71 kg, 42.58 kg, 54.95 kg and 53.76 kg for individual varieties such as Catla, Common crap, Grass crap, Rohu and Silver carp respectively. The average weight of fish at harvesting was 386.0 g, 502.5 g, 507.0 g, 426.0 g and 632.5 g with 64.33 g, 83.75 g, 84.50 g, 71.00 g, 105.42 g average weight gain of fish per month in Catla, Common carp, Grass carp, Rohu and Silver carp respectively. The benefit cost ratio was observed as 2.35 with the net profit of Rs.21,247.50 for 6 months culture period in 0.06 Ha pond area. It was concluded that ostrich and cattle cum fish integration was a suitable and economically viable integrated system in Tamil Nadu.ArticleItem Open Access Stool Characteristics of Obese Dogs Fed on Therapeutic Diets with Altered Levels of Protein and Fibre(2022) Abinaya, A; Karu, Pasupathi; Karunakaran, R, et al.,; TANUVAS24 Labrador retriever obese dogs of more than 3 years age were put in four different treatment groups. The percentage of crude protein and crude fibre of T1, T2, T3 and T4 diet were 15.74 % and 4.09 %; 21.90 % and 11.28 %; 21.73 % and 8.23 %; 15.72 % and 3.99 %, respectively. Including high fibre in the diet affects the stool characeristics. This study aimed to find out the safe level of fibre to promote weight loss without affecting the stool characteristics. The stool score was lowest in dogs in T2 (2.16 ± 0.16 to 2.83 ± 0.16). The frequency of defecation had no significant difference among the treatments. The frequency of defecation was higher in T2 with mean frequency of 1.66 ± 0.21 to 1.83 ± 0.16, when compared with other groups. The pH of the stools was significantly different between the treatments. Higher acidic pH was noticed in T2 (4.91 ± 0.20 to 5.25 ± 0.17) followed by T3, T4 and T1.The present study showed no incidence of diarrhea throughout the trial period in any group.
