    Evaluation of housing and summer management practices adopted by buffalo farmers in Namakkal District, Tamil Nadu
    (2024) Boopathi, V; TANUVAS
    A study was conducted to examine the housing and summer management practices of buffalo farmers in the Namakkal district of Tamil Nadu. A random sample of 120 farmers was selected for this study. The findings revealed that 75% of the farmers housed their buffaloes in thatched roof sheds with mud flooring, accounting for 91.66% of the cases. Additionally, 16.66% of the respondents provided cement concrete mangers for their buffaloes. Most farmers were found to heap dung in manure pits, which was later utilized as farmyard manure. The buffalo sheds generally had proper ventilation. The study suggested that enhancing the knowledge of housing management among buffalo farmers in the Namakkal district could lead to improved buffalo management and subsequently better livelihoods.

    A field study was conducted with different silvi-pastoral systems established at Livestock Farm Complex, Veterinary College and Research Institute, Namakkal during the year 2022 and 2023. There were combination of seven treatments replicated thrice in randomized block design. The treatment consist of productive performance of different silvipasture systems T1 - Cenchrus ciliaris + Stylosanthus scabra (3:1 ratio), T2 - Hardwickia binata with understorey of Cenchrus ciliaris, T3 - Hardwickia binata with understorey of Cenchrus ciliaris + Stylosanthus scabra (3:1 ratio), T4 - Hardwickia binata with understorey of natural pastures, T5 - Azardiracta indica with understorey of Cenchrus ciliaris, T6 - Azardiracta indica with understorey of Cenchrus ciliaris + Stylosanthus scabra (3:1 ratio) and T7 - Azardiracta indica with understorey of natural pasture. In the existing 10 years old Hardwickia binata and Azardiracta indica with a tree to tree spacing of 6 m x 6 m was taken up for the study. In the existing trees of Hardwickia binata and Azardiracta indica with fodder crops viz., Cenchrus ciliaris and Stylosanthus scabra and trees along with natural pastures were compared. The parameters of density, dry matter, biomass yield (Cenchrus equivalent yield) and proximate composition (Dry matter basis) of fodder crops, trees and natural pastures were recorded. The observations were recorded in three times during a year viz, Last week of July, First week of October and First week of January. The pooled data in two year experiment revealed that, T3 - Hardwickia binata with understorey of Cenchrus ciliaris + Stylosanthus scabra (3:1 ratio) recorded higher density, dry matter and biomass yield followed by T6 - Azardiracta indica with understorey of Cenchrus ciliaris + Stylosanthus scabra (3:1 ratio) recorded higher biomass yield when compared to other treatments. The nutrient content particularly crude protein content was recorded higher in T3 - Hardwickia binata with understorey of Cenchrus ciliaris + Stylosanthus scabra (3:1 ratio) and T6 - Azardiracta indica with understorey of Cenchrus ciliaris + Stylosanthus scabra (3:1 ratio).

    Ultrasonographic evaluation of fetal echo biometry and serum progesterone changes in normal and aborted pregnancies in bitches
    (2024) Umamageswari, J; Deepanshi, K; Anil Kumar, R; et al.; TANUVAS
    Thirty bitches of different breeds, weighing 5 to 40 kg and aged between 2 to 6 years presented to the Small Animal Gynaecology unit of Madras Veterinary College, Chennai for pregnancy diagnosis (after 30-35 days of mating) and were divided into three groups of 10 bitches each as Group I (Abortion), II (Foetal Resorption) and III (Normal pregnancy). Foetal echo biometry and serum progesterone estimation were done. Fetal heart rate from the 5th week of pregnancy was significantly lower in abortion (235.2±9.75) and resorption (203±5.49) groups. As gestation age advances, a significant reduction in the fetal heart rate was observed in group I. Gestational sac diameter during the 7th week of gestation was significantly higher (p<0.05) in normal pregnancy (G-III) bitches (4.02±0.41 cm) than in G-II and G-I. During 5th week of gestation, bitches with normal pregnancy (G-III) had significantly higher (p<0.01) placental diameter (0.49±0.03 cm) than the bitches in abortion and resorption groups. Progesterone concentration in the abortion group was (8.81 ng/ml) found to be significantly lower than that of the normal pregnancy group (10.32 ng/ml). In conclusion, it was found that the bitches in abortion and resorption groups had significantly lower fetal heart rates and lower progesterone concentration than normal pregnant bitches indicating fetal/maternal stress in bitches.

    Prostatic abscess and feminization associated with bilateral seminoma in a cryptorchid dog
    (2024) Leka Devi, S; Ravi, R; Gopikrishnan, D; et al.; TANUVAS
    A ten years old bilateral cryptorchid male German shepherd dog was presented to Small Animal Gynaecology and Obstetrics Unit, Veterinary College and Research Institute, Namakkal with the history of reduced appetite, stranguria, weight bearing lameness, staggering gait and pyuria for past five days. On physical examination, the dog was emaciated with bilateral alopecia and enlargement of udder and teats and digital rectal palpation revealed enlarged prostate. Ultrasonography revealed sediments in the bladder, enlarged prostate with hypoechoic contents inside prostate and undifferentiated mass in the both side of abdominal cavity caudal to the kidney. The case was tentatively diagnosed as bilateral testicular tumour with prostate abscess. Haematology revealed thrombocytopenia, leucocytosis with neutrophilia and serum biochemistry revealed no pathological changes except hypoglycaemia. Serum hormonal evaluation revealed elevated estrogen and reduced testosterone concentration suggesting testicular tumour. Coeliotomy was performed and removed the two enlarged polymorphic retained testicles. Prostate was exteriorized and 20 ml of pus was aspirated from the prostate and flushed with metronidazole. Animal was treated post-operatively with Ringer’s lactate (10 ml/kg) Amoxycillin and sulbactum (15 mg/kg), pantaprazole (1 mg/kg), metronidazole (15 mg/kg) twice daily and Tramadol (2 mg/kg) for 3 days.
