2018
H.H. Emeash | A.S. Mostafa | N. M. Abdel-Azem
Thirty apparently healthy lambs with average weight and age of 5.8±0.5 kg and 15±1.6 days respectively were chosen in Sids Agricultural Research Station belonging to Animal Production Research Institute in Beni-Suef governorate to investigate the effect of castration and docking on maintenance behaviour and blood cortisol level during and after such operations. Lambs were classified into castration (n=10), docking (n=10) and control (n=10) groups. The results revealed that castration and docking could significantly affect the behaviours of standing idle, recumbency, sleep, suckling and ingestion in lambs. Moreover, blood cortisol level was significantly (p<0.05) increased after operation in castrated and docked lambs as compared to the time before, at operation and 3 hours after operation.

Keskin, Nevra | Demirbas, Yasemin Salgirli
A dog was presented to Ankara University veterinary teaching hospital with 7-year history of acral lick dermatitis. History and clinical findings were consisted with Obsessive compulsive disorder/Compulsive behavior disorder (OCD/CD). Complete improvement was observed with the behavior modifications without the use of medication in the patient. The present report suggests that the correct behavioral therapeutic approach combined with the patience of the doctor and owner, play a key role to reach a successful outcome even without medication in the dogs with OCD/CD.

2018
R. A. Darwish | S. M. El-Bahr
New-born lambs have limited energy reserves and need a rapid access to colostrum to maintain homeothermy and survive. The object of this study was to investigate the importance of neonatal lamb behaviour in the maintenance of its body temperature and survival. The time taken to stand and suck after birth and rectal temperatures were determined in 72 crossbred lambs (progeny of crossing 1/2 Rhamani and 1/2 Finnish). In addition, blood samples were collected at 1, 24 and 72 h after birth. The obtained sera were assayed for thyroid hormones (T3 and T4), known to be involved in heat production and phosphorous element (ph) which is essential for energy metabolism. The obtained results revealed that, low birth weight and triplet lambs were behaviourally less active at birth and had less T3, T4, Ph and body temperatures values over the first 3 days of life than lambs of heavy or medium birth weight and single or twin lambs. Thus, light weight and triplet lambs were highly susceptible to hypothermia and were exposed to high rate of mortality (18.75 and 16.66%) during the neonatal period than other lambs (3.84, 10.00, 4.55, and 9.38 %, respectively). Therefore, the present study concludes that neonatal lamb behaviour, specifically success in standing and obtaining colostrum are extremely important for thermoregulation and survival of the neonate.

2013
Kang, M.H., Konkuk University, Seoul, Republic of Korea | Lee, C.M., Konkuk University, Seoul, Republic of Korea | Sung, H.J., Konkuk University, Seoul, Republic of Korea | Park, H.M., Konkuk University, Seoul, Republic of Korea
An 11-year-old, toy poodle dog was presented with dermatologic lesions and mammary gland tumor (MGT) evaluation. A solitary, lobulated MGT (size 2.5 × 3.5 cm) was affecting the 5th left mammary gland. Firm, oval plaque skin lesions were present on the left dorsal carpal area. The skin lesions were alopecic and salivary staining. The dog had historical separation anxiety and excessive licking of skin lesions were observed. Based on the clinical and histopathologic examinations, MGT was diagnosed with mammary complex adenoma and the skin lesions were diagnosed with acral lick dermatitis. Behavior modification treatment using oral clomipramine was effective.

2012
Minka N. Salka | Ayo J. Olusegun
The aims of this study were to determine the modulating role of ascorbic acid (AA) on rectal temperature (RT), heterophil to lymphocyte (H to L) ratio and aberrant behaviours of ostrich chicks transported by road for 4 h during hot-dry conditions. Twenty ostrich chicks aged 2.5 months, of both sexes and belonging to the Red Neck breed, served as subjects of the study. The chicks were assigned randomly to AA-treated and control groups, consisting of 10 chicks each. The AA-treated group was administered orally with 100 mg/kg body weight of AA dissolved in 5 mL of sterile water 30 min before transportation, whilst the control group was given the equivalent of sterile water only. The thermal load (TL) experienced in the vehicle during transportation fluctuated between 31 °C and 89 °C, as calculated from the ambient temperature and relative humidity. Transportation induced hyperthermia, lymphopenia, heterophilia and aberrant behaviours of pecking, wing fluffing and panting, which were ameliorated by AA administration. The relationships between the TL, journey duration and physiological variables of RT, H to L ratio and aberrant behaviours recorded during transportation were significantly and positively correlated in the control group. In AA-treated group the relationships were not significantly correlated. In conclusion, the results showed for the first time that AA ameliorated the adverse effects of stress caused by road transportation on the aberrant behaviours, RT and H to L ratio of ostrich chicks during the hot-dry season.

2005
R. A. Darwish
Survival of the neonate relies on the integrated expression of appropriate behaviours from both mother and young. In this study, the effect of birth difficulty on maternal and lamb behaviours and its influence on lamb survival was investigated in crossbred primiparous ewes (½ Finnish x ½ Rahmani). Assisted ewes spent significantly (P<0.05) less time licking (30.83±1.39 min/2 h) and nosing (24.25±1.79 time/2 hr) their lambs than unassisted mothers (38.52±2.96 min, 28.80±1.68 time/2 h) respectively. They were found to be more aggressive towards their lambs when attempt to suck (9.80±0.37, 12.90±0.84 and 10.50±0.50 time/2 h) when compared with unassisted one (8.00±0.40, 10.20±1.52 and 7.66±0.88 time/2h) respectively. Lamb behavioural development were found to be significantly (P<0.05) affected by birth difficulty with lambs that require assistance at birth even if they survive the birth process, they were slower to progress through the sequence of neonatal behaviours. These lambs were therefore at greater risk of not surviving to weaning (28.57% vs. 11.42). It could be concluded that ease ofdelivery was an important factor determining the subsequent behaviour of the lamb and ewe and hence lamb survival, thus manipulation of husbandry and breeding system to improve delivery will improve lamb survival

Various types of pain were reported by people with Plasmodium falciparum and were mostly attributed to a symptom of malarial infection. Neural processes of pain sensation during malarial infection and their contributions to malaria-related death are poorly understood. Thus, these form the focus of this study. Swiss mice used for this study were randomly divided into two groups. Animals in the first group (Pb-infected group) were inoculated with Plasmodium berghei to induce malaria whilst the other group (intact group) was not infected. Formalin test was used to assess pain sensitivity in both groups and using various antagonists, the possible mechanism for deviation in pain sensitivity was probed. Also, plasma and brain samples collected from animals in both groups were subjected to biochemical and/or histological studies. The results showed that Pb-infected mice exhibited diminished pain-related behaviours to noxious chemical. The observed parasite-induced analgesia appeared to be synergistically mediated via µ-opioid, α2 and 5HT2A receptors. When varied drugs capable of decreasing pain threshold (pro-nociceptive drugs) were used, the survival rate was not significantly different in the Pb-infected mice. This showed little or no contribution of the pain processing system to malaria-related death. Also, using an anti-CD68 antibody, there was no immunopositive cell in the brain to attribute the observed effects to cerebral malaria. Although in the haematoxylin and eosin-stained tissues, there were mild morphological changes in the motor and anterior cingulate cortices. In conclusion, the pain symptom was remarkably decreased in the animal model for malaria, and thus, the model may not be appropriate for investigating malaria-linked pain as reported in humans. This is the first report showing that at a critical point, the malaria parasite caused pain-relieving effects in Swiss mice.

2023
S. Karthikeyan | N. Narmatha | V. Uma | K. Sivakumar | G. Kumaresan
The present study was undertaken to understand the present status of adoption of TANUVAS SMART mineral mixture, viz, complete adoption, partial adoption, discontinuance and rejection and its perceived attributes, namely, relative advantage, compatibility, complexity, observability and trialability using the schedule developed for the purpose and the economic impact. Partial budgeting was done to assess the economic impact of adopting TANUVAS SMART mineral mixture. Personal cosmopolite and personal localite communication channels had contributed majorly to the awareness of the dairy farmers followed by mass media. Majority of the dairy farmers (78%) discontinued the adoption of the innovation. Sixty six per cent of them had medium level of adoption behaviour followed by high (28%) and low (6%) level of adoption behavior. The reasons attributable were that the technology was perceived relatively less advantageous and not observable. However, it was perceived as highly compatible, less complex and trialable. Net income of the dairy farmers had increased by Rs. 2,216.80 per dairy animal per lactation due to the adoption of TANUVAS SMART Mineral Mixture. The status of adoption of TANUVAS SMART Mineral Mixture, its adoption behaviour and change in net income were found to be significantly associated with land holding, area under fodder cultivation, dairy animal possession, extension agency contact and mass media exposure of the dairy farmers.
