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.

The present study was conducted to study the white blood corpuscles of Emu. The blood samples were collected from eight apparently healthy adult Emu birds and blood smears were stained with modified Wright stain for cyto-morphological studies of various white blood corpuscles. The Heterophils were round cells with lobed nucleus which was placed eccentrically. The Eosinophils often had a bi-lobed nucleus with abundant small, round, red - to - pink granules and light blue cytoplasm. The basophils cytoplasm had densely packed metachromatically stained granules. The small lymphocytes were irregularly round with round nucleus and a lacy chromatin pattern. The large lymphocytes had a homogeneous and an abundant cytoplasm which was more basophilic. The Monocytes were large cells with moderate amounts of blue - gray cytoplasm that occasionally had small discrete vacuoles. Their nuclei were pleomorphic with a lacy chromatin pattern. Deviation from the normal morphology of White Blood Corpuscles indicates disease and pathological conditions in Emu.

The morphology of the abducent nucleus of the buffalo has been described by materials collected from eight buffalos. Nissl and myelin stained serial and semi serial sections of brain stem were used for the study. The abducent nucleus in the buffalo extended from the cranial pole of the rostral cochlear nucleus to the caudal pole of the motor nucleus of the trigeminal nerve. An accessory abducent nucleus which is present in amphibians, reptiles, birds and some mammals could not be identified in the buffalo. The nucleus appeared as a rounded body in its caudal pole and was roughly triangular at rostral pole in transverse sections. The average length of motor nucleus of abducent nerve in the buffalo was 2.4 mm. The average maximum width and height of the nucleus was 1.48mm and 1.75 mm respectively.

Contamination of locally fermented cow milk (Nono) by pathogenic bacteria constitute a major public health problem. This was because contaminated milk was a good medium that can support the growth and propagation of microbial pathogens. This study was designed to assess the bacteriological quality of locally fermented cow milk consumed in Maiduguri, northeastern Nigeria. Totally, forty (n = 40) samples of fresh, locally fermented cow milk (Nono) were collected and used in this study. Ten (10) milk samples each were collected from four randomly selected selling points (Monday Market, Custom Market, Kasuwan Shanu and Tashan Bama). The bacteriological quality of each milk sample were analysed using standard procedures for isolation, identification and enumeration of pathogenic bacteria. The mean total plate count ranged from 1.44x10 8 CFU/mL to 10.31x10 8 CFU/mL, while the mean total coliform count range from 0.57x10 8 CFU/mL to 11.17x10 8 CFU/mL. Statistically, there was a significant difference (p<0.05) in the mean total plate count and coliform count of milk samples collected from the four sampling points.Bacteriological culture and biochemical identification of all the isolates revealed Escherichia coli29(72.5%), Klebsiella specie3(7.5%), Salmonella specie 2(5%), Staphylococcus aureus 14(35%) and Streptococcus specie15(37.5%) respectively. All the results were above the acceptable limits (1.0 to 3.0 x 10 5 CFU/mL for total plate count and no coliform count per 100ml of milk sample) set by NAFDAC. Therefore the Nono products consumed in Maiduguri was not safe and wholesome for public consumption. Hence, the need to ensure the maintenance of standard hygienic protocols during the collection, storage, processing and marketing of locally fermented cow milk (Nono) in order to minimize microbial contamination.

Drug interaction is the effect produced by combination of various drugs administered in a biological system which may produce beneficial or adverse effects.Due to continuous usage of antibiotics to bacterial infections, pathogenic bacteria developed resistance mechanisms which leads to reduced antibacterial activity of different antibiotics. Combination of antibiotics with phytochemicals became an alternative to enhance the efficacy of antibiotics. In this connection,in the present study, the effect of certain phytochemicals namely Quercitin, Morin, Ellagic acid,  Chloragenic acid Rutin and Naringenin in combination with antibiotics Amoxycillin and Ciprofloxacin were evaluated. Staphylococcus aures and Escherichia coli were used as test organisms. They were isolated from the mastitis milk samples and their presence was confirmed using Polymerse Chain Reaction .The antibacterial activity of the antibiotics and antibiotics in combination with phytochemicals were determined using broth dilution method and agar well diffusion assay. The MIC and zones of inhibition were used as indicators for drug interaction.

A biological trial was conducted to study the effect of multi enzyme supplementation on ileal digestibilities of dry matter (DM), crude protein (CP), ether extract (EE), phytate phosphorus (PP) and non-starch polysaccharides (NSPs) in terms of neutral detergent fibre (NDF), acid detergent fibre (ADF), hemicellulose and cellulose in broilers for a period of 0-6weeks. The broilers used in this trial were fed diets supplemented with enzyme at 0, 250, 500, 750 and 1000 g/ton of feed with a proportionate reduction in metabolizable energy (ME-1.25, 2.5, 3.75 and 5 %), crude protein (CP-0.75, 1.5, 2.25 and 3 %), methionine + cytine (0.5, 1, 1.5 and 2 %) and available phosphorus (2.2, 4.4, 6.6 and 8.8 %). The level of individual enzyme per gram of multi enzyme supplement was cellulase 146 IU, xylanase 241 IU, pectinase 98 IU, protease 74 IU, amylase 778 IU and phytase 33 IU. The ileal digestibility was conducted on 6 th week of trial. The ileal DM digestibility (%) was significantly (p<0.01) increased in 750 g and 1000 g enzyme supplemented groups than other treatment groups. The increase in ileal DM digestibility was significantly (p<0.01) higher (6.2 %) in the group fed with 750 g enzyme supplementation than control. The digestibility of ileal crude protein (%) significantly (p<0.01) increased in 500, 750 and 1000 g enzyme supplemented groups than control. The increase in ileal protein digestibility was 12.20 % in 500 g/ton, 9.90 % in 750 g/ton and 10.12 % in 1000 g enzyme supplemented groups than control. However a non significant difference was observed in ileal EE digestibility in all treatment groups. The ileal phytate phosphorus digestibility significantly (p<0.01) increased in all the enzyme supplemented groups (33.69 % in 250 g/ton, 38.75 % in 500 g/ton, 39.53% in 750 g/ton and 42.11% in1000 g/ton) than control (31.71%). A highly significant (P< 0.01) increase in ileal neutral detergent fibre (NDF) and hemicellulose was observed in 500 to 1000 g enzyme supplemented groups than control. Similarly significant (P<0.01) increase in ileal acid detergent fibre (ADF) and cellulose digestabilities (%) were observed in all enzyme supplemented groups than control. It was concluded that the multi enzyme supplementation at minimum inclusion level of 500 g per ton of feed increased the ileal digestibilities of CP, PP, NDF, ADF, hemicelluloses and cellulose by 12.20 %, 18.17 %, 13.57 %, 55.63 % 12.77 % and 52.64 % respectively than control in broiler diet than the control diet in broilers.

A three years old male pigeon weighing 400g (racing homer) was presented to Madras Veterinary College Teaching Hospital with the history of soft tissue growth on the keel region for the past six months and gradually increase in size was noticed. Physical examination revealed large tennis ball size soft tissue mass on the keel region. Cytological examination revealed the presence of inflammatory cells with serosanguineous background. Radiological examination revealed presence of soft tissue mass on the keel bone with no bony involvement. Surgical resection of tumour mass was performed under general anaesthesia. Histopathological examination confirmed liposarcoma in a pigeon. The bird recovered uneventfully on 10 th post-operative day without any complications.

The aim of this study was to evaluate two different superovulation protocols for quality embryo production. Donor animals were selected (Day 0) and a progesterone device was inserted. The superstimulatory treatment was initiated in day 7 (D7) with follicle stimulating hormone from porcine (FSHp) in eight decreasing doses each at 12 hours interval. Along with the fifth dose of FSHp, 500μg cloprostenol was administered. The progesterone device was removed 12h (Treatments P12) and 24 h after the first application of cloprostenol (Treatments P24). Twelve hours after the eighth dose of FSHp (D11) 25µg of Buserelin was administered and the inseminations were done after 12 and 24 hours. Embryos were collected in the forenoon of D18. P24 presented better results than the P12 treatment.

A survey was conducted among the small holder dairy farmers in 80 Panchayaths of 14 districts in Kerala in order to evaluate the reproductive performance of crossbred cattle population in Kerala at field level. Analysis of the data showed that the herd size of cattle in Kerala was around 3 per house during the period of 2012 and 2013. Three fertility traits, age at first calving (AFC), calving interval (CI) and number of services per conception (NSC) were studied in detail and the averages of these traits were 1093 ± 10.52 days, 551 ± 48 days and 2.02 ± 0.01 services per conception, respectively. Fixed model analysis was carried out to see the effect of some of the major factors leading to variation in AFC, CI and NSC and found that there was significant difference in reproductive performances among different genetic groups. AFC and NSC of crossbred Holstein Friesian cows and CI of Sunandini cows were lower compared to other genetic groups. Other factors significantly influencing AFC were period of birth and season of birth. Apart from genetic groups, number of services per conception was influenced by type of semen used and also the level of peak milk production.

The study was conducted on repeat breeding cows at Large Animal Gynaecology Ward, Department of Clinics, Madras Veterinary College, Chennai and some private cattle farms in and around Koduvalli region, Tiruvallur district, Tamil Nadu. In experiment I, Jersey crossbred cows (n=31) synchronized by PGF2a and inseminated on exhibited estrum. The cows were randomly divided into five groups viz. Group I (control, n=6), group II (n=7,100mg), group III (n=6, 150mg), group IV (n=6, 200mg) and group V (n=6, 250mg) and supplemented with fish meal on day 13, 14 and 15 of post insemination in addition to their routine feed. Pregnancy diagnosis was carried out by rectal palpation on day 60 of post insemination. In experiment II, twelve repeat breeding Jersey crossbred cows were selected and synchronized using PGF2a followed by timed insemination. On day 10 of post estrus, rectal examination was performed to identify the corpus luteum and randomly divided into two group viz. Group I and Group II (control). Group I cows were injected with Meloxicam @ 0.5 mg/ kg body weight through intramuscularly on day 13 to 15 post-insemination. The conception rate in experiment I as in Group I, group II, group III, group IV and group V are 16.67%, 71.43%, 66.67%, 66.67% and 50.0%, respectively. The conception rate in meloxicam treated animal was 66.7% and in control animal was 33.3%. The fish meal treatment and Cox-2 inhibitor in repeat breeding crossbred cows had improved the conception rate. Further, the supplementation of 100mg offish meal in repeat breeding cows has shown higher conception rate as compared to other groups in experiment II. Hence, it may be used in field condition for enhancement of conception rate, however, further studies in larger population is warranted.
