(IF 1.8) Pub Date : 2023-12-14 Muhammad Shakeel Khaliq, Mobeen Sarwar, Farhat Nazir Awan, Halima Sadia, Aamir Saleem, Syed Abdul Khaliq, Muhammad Hassan Mushtaq, Mamoona Chaudhry, Abdul Rehman
Foot and Mouth Disease (FMD) is a transboundary animal disease that causes major economic losses to the livestock industry in developing countries like Pakistan. In this cross-sectional study, a total of n = 315 serum samples were collected from 92 FMD unvaccinated sheep and goats flocks among three districts (Chakwal, Dera Ghazi Khan, and Jhang) of Punjab province, Pakistan. These serum samples were

Bovine amniotic membrane stem cell-conditioned medium improves the culture conditions for in vitro produced ovine embryos Small Rumin Res. (IF 1.8) Pub Date : 2023-12-10 Mahura Nikoobin, Ebrahim Ahmadi, Naser Shams-Esfandabadi, Hassan Nazari, Najmeh Davoodian
Despite the progress in in vitro embryo production technology, the quality of embryos produced in vitro remains inferior to that of embryos produced in vivo. There have been reports highlighting the beneficial impacts of stem cells and their conditioned medium on the in vitro maturation of oocytes and the in vitro culture of embryos. In this study, we investigated the effects of adding bovine amniotic

Electrocardiographic, clinical and haematological evaluation of propofol and xylazine-ketamine anaesthesia in Goat Small Rumin Res. (IF 1.8) Pub Date : 2023-12-05 Mrigakshi Yadav, Sunil Kumar Rastogi, Arun Kumar Madan, Arup Kumar Das, Ruokuobeinuo Huozha, P. Manjari, Sudheer Kumar
Limited information is available to ascertain the quality of intravenous anaesthetic regime predominantly practised in goats for short term surgical interventions. Clinical, electrocardiographic and haematological studies were conducted on twelve female Barbari crossbred goats, aged 2–4 years to assess the anaesthetic quality of propofol and xylazine-ketamine combination. Onset, duration and recovery

Saanen and Alpine goats experience neophobia when offered novel feeds Small Rumin Res. (IF 1.8) Pub Date : 2023-12-05 Angélique Favreau-Peigné, Ophélie Dhumez, Cécile Ginane, Hans W. Erhard
Feed neophobia is a reluctance to eat a novel feed that can last from minutes to days. While it can prevent animals from ingesting toxins, it may also have negative effects on growth and animal welfare. In ruminants, feed neophobia has mainly been studied in sheep and cattle, and only a few studies have focused on goats. This study assessed feed neophobia in goats and aimed to determine whether this

Investigation of the effects of pulmonary adenomatosis on oxidative dna damage, inflammation, apoptosis, and autophagy in lung tissues in sheep Small Rumin Res. (IF 1.8) Pub Date : 2023-12-05 İsmail Bolat, Serkan Yildirim, Yavuz Selim Sağlam, Selim Çomakli, Metin Kiliçlioğlu, Esra Dereli
Pulmonary adenomatosis infections are an infectious and neoplastic disease that affects the respiratory system in sheep. Although the existence and prevalence of this disease have been revealed in studies, there is no definitive treatment today. Diagnosis of the disease; It can be detected by clinical, macroscopic, microscopic, and immunohistochemical methods. Although there are studies reporting the

Bottlenecks analysis using analytic hierarchy process (AHP) throughout the value chain of small ruminants in India Small Rumin Res. (IF 1.8) Pub Date : 2023-12-03 Akshita Chadda, Jaswinder Singh, R.K. Sharma, Ravi Kant Gupta, S.K. Kansal
Bottlenecks are the obstacles that impede the accomplishment of an intended purpose and consequently, endure a dampening effect on the chain's effectiveness and profitability. This study was aimed to explore the bottlenecks confronted by small ruminant farmers in the value chain in India. A total of 385 small ruminant farmers from 11 districts of Punjab were selected purposively, proportionate to the

Effect of the addition of platelet-rich plasma to Boer buck semen on sperm quality and antioxidant activity before and after cryopreservation and in vivo fertility Small Rumin Res. (IF 1.8) Pub Date : 2023-11-30 Maha S. Salama, Ahmed M. Shehabeldin, Mohey A. Ashour, Muath Q. Al-Ghadi, Basma H. Marghani, Ismail El-kon, Mustafa Shukry
The current study aimed to investigate the effects of incorporating platelet-rich plasma (PRP) into Boer buck semen at different stages of cryopreservation (dilution, equilibration, and post-thawing) on sperm quality, functionality, antioxidant activity, and in vivo fertility. One hundred sixty ejaculates were collected from eight Boer goat bucks over ten weeks during the breeding season. The semen

Anti-Mullerian hormone profile and its association with ovarian parameters in the Chaugarkha goat Small Rumin Res. (IF 1.8) Pub Date : 2023-11-29 Nitish Singh Kharayat, Madhusoodan Aradotlu Parameshwarappa, Gurav Amol Ramdas, Deepika Bisht, Siddharth Gautam, Sanjay Kumar Singh, Narayanan Krishnaswamy, Karam Chand, Ajayta Rialch, Pradeep Chandra, Brijesh Kumar
Circulating anti-Mullerian hormone (AMH) is a potential predictor of ovarian reserve in the woman and livestock. Only two such studies are reported in the goat. Accordingly, we investigated the effect of age, estrous cycle and early pregnancy on the serum AMH and its correlation with the ovarian parameters in the Chaugarkha goat. In experiment-1, a random blood sample was collected from the goats (n = 62)
