The response of Japanese quail to supplementation of Morinda citrifolia truit juice with reference to growth, production and immune response was studied. The Japanese quail were fedMorinda citrifolia ITuitjuice @5% from 0-7 weeks during growing period and from 8-14 weeks during laying periods. The body weight gains, feed conversion ratio, performance index and immunity status were recorded in both control and treated groups. The result revealed better growth performance in theMorinda fed groups compared to the control group. Overall performance index of Morinda group was also better than control group. The humonil immune response ofthe Morinda group was significantly better than control group. The Morinda fed birds produced 30.90 eggs / hen housed during 8-14 weeks of age. While only 20.9 eggs/hen housed produced by control groups. The overall analysis of the growth and production performance of both the groups revealed that supplementation of M. citrifolia crude truit juice @ 5% daily enhanced the body weight gain and egg production performance in the Japanese quail.

The experimental trial of six weeks was undertaken on 90 broiler chicks divided into three groups. Control (To) group was fed standard broiler diet and T1 and T2 groups were provided same broiler diet supplemented with 300 and 500 mg of Spirulina per kg feed, respectively. Mean live body weight of six weeks of the experiment and live weight at the end of experiment were found to be significantly (P0.05) higher in Spirulina supplemented T1 and T2 groups of broilers than that of control (To) group. Comparatively better mean weekly weight gain and feed efficiency were also observed in Spirulina supplemented groups (T1 and T2)with decreased feed consumption as compared to control (To) group of broilers.

An experiment (97 days) was conducted to investigate the dietary lauric acid (LA) supplementation on performance, digestibility and faecal microflora counts in Large White Yorkshire cross piglets. A basal diet was (BD) prepared as a negative control without supplementation and a positive control with an antibiotic (chlortetracycline at 0.05%) supplementation (BDA). Another two diets were prepared by supplementing LA at 0.2 and 0.4% levels to the basal diet. Dietary inclusion of LA or antibiotic significantly (P<0.01) improved the body weight and feed efficiency and recorded highest (P<0.01) body weights with 0.4% LA, while lowest (P<0.01) weight gain with control group. Significantly higher FCR (P<0.01) was observed in LA fed animals and the lowest (P<0.01) was recorded in the BD and BDA groups. The improved (P<0.05) digestibility of organic matter, crude fiber, ether extract and nitrogen free extract was observed with 0.4% LA. The faecal total bacterial count and E.coli count were lowered (P<0.01) with LA supplementation, while highest count was observed in control group. Hence, it was concluded that, supplementation of LA at 0.2 to 0.4 % in the diets of LWY piglets showed increased weight gain, feed efficiency and nutrient digestibility by reducing faecal microflora count in LWY piglets.

 The experiment was conducted to assess the effect of replacement of maize by wheat bran on growth and feed conversion efficiency in Large White Yorkshire (LWY) pigs. Thirty weaned piglets were randomly divided into three groups and were allotted to the three dietary treatments, T1 (control ration as per NRC, 1998), T2 (50 per cent of maize of control ration replaced by wheat bran) and T3 (100 per cent of maize of control ration replaced by wheat bran) and maintained for 70 days. The daily feed intake, fortnightly body weight were recorded and average daily gain and feed conversion efficiency were calculated. The average daily gain and feed conversion efficiency were 813.00, 769.86, 678.43 g and 2.80, 2.88, 3.08, respectively for three dietary treatments. There was no significant difference in the performance between pigs belongs to T1 and T2 treatments but had higher average daily gain and feed conversion efficiency than that of T3 treatment. This study reveals that pigs fed diet with 50 per cent of maize replaced by wheat bran performed in a similar way to that of control fed group and was better than those fed diet with 100 per cent replacement of maize by wheat bran.

Multicut fodder sorghum Co (FS) 29 was evaluated for its growth and yield performance with the application of different sources of irrigation and nutrients. The experiment was conducted in split plot design with three replications. Main plot consists of treatments with application of irrigation through ground water (I1), domestic sewage water (I2) and ground and domestic sewage water alternatively (I3). The sub plots consist of no fertilisers (control) (N1), application of farm yard manure alone (FYM alone) (N2), farmyard manure + NPK (FYM + NPK) (N3) and NPK alone (N4). The application of domestic sewage water along with FYM + NPK nutrients as per the treatment schedule resulted in higher plant height, leaf length, number of leaves, biomass production, dry matter and biomass yield of multicut fodder sorghum. However, pertaining to nutrient application, nitrogen uptake was higher with application of FYM +NPK but found on par with the application of NPK alone and application of FYM alone.

An experiment was conducted on 18 un-castrated crossbred (Beetal x Assam local) kids of 3-4 months of age to study the effect of shed roof colour and bedding materials on growth performance during winter season. Three groups of six kids in each were housed in three sheds: T1 (shed roof painted with black colour on top and white colour inside and paddy straw bedding material mixed with hydrated lime, T2 (shed roof painted with black colour on top only and paddy straw without any treatment and T3 (shed roof without any colour and bedding material). The shed T1 and T2 were covered with hessian clothes except the ventilators. The roof shed painted with black colour on top and white colour inside along with hydrated lime mixed bedding material (T1) might have provided better and comfortable micro environment both in terms of optimum temperature and hygienic condition that resulted in significantly (P<0.010) higher body weight in kids (9.59 ± 0.20 kg) than T2 (9.15 ± 0.17 kg) and T3 (8.96 ± 0.0.33kg) respectively.
