Recent intercontinental spread of highly pathogenic avian influenza (HPAI) A(H5N1) among kept and wild birds and transmission to mammalian hosts, including cattle and humans has heightened the need to review public health risk assessments. Biosecurity is essential for limiting disease spread, but how widely practices are implemented is not fully kn...

The Avian Contact Study is a cross-sectional questionnaire of poultry workers and other individuals who have contact with domestic and/or wild birds in the UK. The questionnaire was launched online in May 2024 and in-person responses were gathered at the British Pig and Poultry Fair in Birmingham on 15 and 16 May 2024. This Data Note documents ques...

White radish root is rich in phytochemicals with high antioxidant properties, which are needed for the amelioration of heat stress in tropical rabbit production. This study investigated the effect of oral administration of white radish root juice (WRRJ) on growth performance, physiological response, and blood profile of rabbit bucks in a hot humid...

This review summarizes the available information on the adaptation and the performance of White Fulani cattle in tropical environments. White Fulani cattle is an indigenous breed of cattle widely distributed in the humid tropical regions of Africa and plays significant roles in meat and milk production, as well as draught purposes. Poor management...

This study investigated the effect of sweet orange peel powder (SOPP) supplemented water on the rectal temperature (RT), respiratory rate (RR) and blood profile of broiler chickens raised in a hot humid environment. Day-old Ross broiler chickens (n = 96) were randomly allotted into four treatment groups: Control-without SOPP, 2 g SOPP, 4 g SOPP and...

The problem of heat stress (HS) in hot regions of the world is further complicated by climate change and the ensuing global warming. Goats have been a means of sustenance for rural dwellers and people found in resource-poor regions. Goats possess some phenotypic adaptive features that portray them as hardy with ecological adaptability based on anat...

Effects of egg storage length and orientation on hatching traits and spread of hatch were determined in Transylvanian naked neck chicken. Eggs (n=640) stored in a cold room (16±1.5oC, 75±1.5% RH) in batches of 160 eggs each, for 1, 3, 5 or 7d were used. Half of each batch was stored with a broad end up (BEU) and the other in a narrow end up (NEU)....

Ageing in roosters come with several welfare issues such as reduced sexual activity and semen quality. For good productivity, roosters need to be sexually active and produce good quality semen to fertilize eggs produced by the hens. Spices like onion have been reported to enhance feeding and comfort behaviour in broilers, while a combination of oni...

Eggs from Transylvanian naked neck (TN) chickens (n = 560) were stored in cold room (at 16 ± 1.5 o C) in daily batches of 80 eggs each, for 1, 2, 3, 4, 5, 6 or 7d either with broad (BEU) or narrow end up (NEU). Additional day in storage caused significant (P < 0.001) loss in egg weight. Dead in germ (DIG) followed (P < 0.001) the pattern: 5d < 6d <...

In bridging the knowledge gap on stress physiology of Nigerian indigenous chickens, this study investigated the effect of exogenous corticosterone (eCORT) as stress inducing agent on the testicular function and mating behavior of Nigerian indigenous cocks. Twenty-four (24) cocks and one hundred and forty four (144) hens (mating ratio of 1 cock: 6 h...

Genetic improvement of goats requires the selection of superior breeding stock and the application of artificial insemination technique. The successes of artificial insemination in goats generally depend on knowledge of semen preservation and insemination techniques. In this study, the preservative effects of cysteine in Tris-pumpkin seed milk base...

Cryopreservation is a viable reproductive technique but still have detrimental consequences on sperm quality and fertility. This study compared the sperm cryotolerance among different breeds of chickens in hot humid environments. Semen samples were collected from thirty (30) cocks comprising 10 Funaab alpha normal feathers, Arbo acre and dominant b...

Goat plays a vital role in the rural village economy and are critical for food security and livelihood. The contributions of goats to the economy of millions of rural people notwithstanding are hindered by severe heat stress due to the global climate change. Prediction of climate change impact indicate that heat stress is the overriding factor infl...

Tropical environments are characterized by persistently high temperature and relative humidity and the harsh environmental conditions pose a serious limitation on the optimal performance of the animals raised in this region. Heat stress causes deleterious effects on welfare, immunology and physiology of farm animals with a resultant impact on their...

The effect of supplementing drinking water with sweet citrus peel powder (SCPP) on the performance, ileal microbial count, and relative weight of organs of broiler chickens reared in a tropical environment was investigated. Ninety-six (96) 1-day-old Ross broiler chickens, after brooding, were randomly allotted into four treatment groups: T1 (contro...
