Indian Council of Agricultural Research (ICAR) initiated the Field Progeny Testing (FPT) scheme for cross-bred bulls in Kerala in 1985-86 at the Centre for Advanced Studies in Animal Genetics and Breeding (CASAGB), Mannuthy, Kerala. Since 2002, ICAR has incorporated Fr…

Feed cost was the major limiting factor affecting profitability in goat production systems, particularly under smallholder conditions. The present study evaluated the effect of partial replacement of concentrate mixture with hedge lucerne (Desmanthus virgatus) and mulb…

Understanding herd demographic structure is fundamental for evaluating productivity, disease dynamics, and management interventions in dairy systems. This study developed a dynamic production subsystem to represent the progression of female cattle through key physiological and production stages …

The cerebral form of theileriosis with nystagmus, opisthotonus and circling as the predominant clinical signs, is rarely reported in small ruminants. Fifteen goats with many or all of the following neurological signs like circling, head pressing, ataxia, incoordination…

Accurate estimation of the post-mortem interval (PMI) in avian species remains challenging due to rapid post mortem changes and the limited availability of validated external indicators. The present study evaluated the progression of rigor mortis and feather plucking r…

The present study was undertaken to evaluate uteroplacental artery haemodynamics, combined thickness of the uterus and placenta (CTUP) and serum progesterone concentrations in bitches with dystocia. A total of twelve (n = 12) pregnant bitches presented at the time of p…

Ticks are among the most important ectoparasites affecting cattle health and productivity in tropical regions, with chemical acaricides being the primary control strategy. However, indiscriminate and prolonged use of acaricides has resulted in the emergence of resistan…

The prevalence of both neoplastic and non-neoplastic pulmonary masses in rabbits is considered low. Gross examination alone is insufficient to reliably differentiate between these lesions. This study evaluated necropsy cases presented to the Department of Veterinary Pa…

The effect of Gallium–Arsenide laser therapy on burn wounds grafted with decellularised bovine omentum was evaluated in Wistar rats. Sixty rats with experimentally induced third-degree burns and grafted with decellularised bovine omentum were divided into four gr…

The study compared haematological and serum biochemical parameters in bitches with complete primary uterine inertia (PUI) and obstructive dystocia (OD), and evaluated a non-invasive method for monitoring uterine contractions using M-mode ultrasonography. Twelve full te…

Caprine abortion is an important cause of economic loss and may be associated with several zoonotic bacterial pathogens. The present study investigated the occurrence of selected zoonotic bacterial abortifacients among goats in Kerala, India. Aborted materials from 25 …

This study evaluated the effects of different durations of intermittent suckling on weight loss, reproductive hormone profiles, and post-weaning reproductive performance of sows. Sixteen lactating Large White × Landrace sows were randomly allotted to four treatme…

Critical-sized bone defects remain a major challenge in orthopaedic reconstruction because they lack the intrinsic capacity for complete regeneration, while many synthetic grafts fail to achieve optimal bioactivity, biodegradation, and host integration. This study eval…

The findings underscore the importance of region-sensitive strategies for integrating ethnoveterinary knowledge into contemporary livestock health programmes, as adoption patterns differ across the Southwestern states of Nigeria. Of the 12 plants being used, brimstone …

A feeding trial of 120 days was conducted to assess the effect of replacement of paddy straw by shredded arecanut spathe in total mixed ration for crossbred calves on nutrient digestibility and rumen fermentation. Eighteen weaned female crossbred calves of eight to twelve months of age were sele…

Infectious canine hepatitis caused by Canine Adenovirus type 1 (CAV-1) is a systemic disease of domestic and wild canids. Despite the availability of effective vaccines, sporadic infections continue to occur, while information on the molecular epidemiology of CAV-1 in Kerala remains limited. The…

Accurate normalisation of quantitative real-time PCR (qPCR) data depends critically on the use of a stably expressed reference gene. Hence reference genes traditionally assumed to be constitutively expressed can show considerable tissue- and condition-specific variabil…

The kidneys are the essential organ in domestic animals performing major functions namely ultrafiltration, excretion, electrolyte balance, blood pressure and pH regulation and reabsorption of glucose and amino acids. The aim of the study was to investigate the histoarc…

The present study aimed to investigate the presence of Bacillus spp. in chicken waste dumping sites and poultry farms in the Thrissur district to produce extracellular protease. Thirty soil samples were collected from chicken waste disposal sites, as well as from poult…

Newcastle disease (ND), caused by Newcastle disease virus (NDV), is a major viral disease affecting poultry production worldwide. The present study aimed to analyse the comparative expression of prostaglandin-endoperoxide synthase 2 (PTGS2) in embryonated chicken eggs of Gramasree and Tellicherr…
