Modulation of growth performance, feed utilization, and physiological traits in redbelly Tilapia (Tilapia zillii) through environmental and sex ‐based interactions
This study explored the combined influence of tank color, stocking density, and gender onTilapia zillii's performance and well-being. In this 120-day trial, 320T. zillii, each initially weighing 10.0  ± 0.1 g/fish, were distributed among 24 tanks. The experiment included eight distinct treatment combinations, varying tank color (blue and green), stocking density (10 and 30 fish/m3)  and sex (monosexual and mixed). The results showed that blue tanks improved specific growth rate and condition factor, while green tanks were better for feed utilization. Density at 30 fish/m3 showed the highest mean values of final...

In vitro evaluation of the application of an optimized xylanase cocktail for improved monogastric feed digestibility
This study investigated the potential of an optimized binary GH10 and GH11 xylanase cocktail to mitigate the antinutritional effects of xylan on the digestibility of locally sourced chicken feed. Immunofluorescence visualization of the activity of the xylanase cocktail on xylan in the yellow corn of the feed showed a substantial collapse in the morphology of cell walls. Secondly, the reduction in the viscosity of the digesta of the feed by the cocktail showed an effective degradation of the soluble fraction of xylan. Analysis of the xylan degradation products from broiler feeds by the xylanase cocktail showed that xylotrio...

Strategies to combat heat stress in poultry production —A review
AbstractThe effects of heat stress (HS) caused by high temperatures continue to be a global concern in poultry production. Poultry birds are homoeothermic, however, modern-day chickens are highly susceptible to HS  due to their inefficiency in dissipating heat from their body due to the lack of sweat glands. During HS, the heat load is higher than the chickens' ability to regulate it. This can disturb normal physiological functioning, affect metabolism and cause behavioural changes, respiratory alkalosis a nd immune dysregulation in birds. These adverse effects cause gut dysbiosis and, therefore, reduce nutrient absorpt...

Identification of Eimeria acervulina (Apicomplexa: Eimeriidae) infecting the broiler chicken Gallus gallus domesticus through morphology and molecular analyses
This study highlighted the importance of molecular techniques to detect avianEimeria species more than the traditional morphology-based tool to optimise the appropriate anticoccidial strategies for long-term control in the studied area. (Source: Journal of Animal Physiology and Animal Nutrition)

Ketogenic diets: A systematic review of current scientific evidence and possible applicability in dogs and cats
The objective of this review was to highlight recent studies about the application of KD in dogs and cats, to describe the neurobiochemical mechanisms through which KD improves epilepsy crisis, and their adverse effects. Studies were identified by a systematic review of literature available on PubMed, Embase, and Scopus. All cohort and case-control studies were included, and all articles were exported to Mendeley ® citation manager, and duplicates were automatically removed. Seven articles and three conference abstracts conducted with dogs were included in the present study. There is evidence that the consumption of diets...

Dietary hydrolyzed soya lecithin affects feed intake, abundance of bacteria in the caecum, fatty acid composition and area of adipocytes in pre ‐mating primiparous V‐line female rabbit
In conclusion, soya lecithin at a dose of 0.5% increased feed intake and energy storage in adipocytes and improved the fatty acid profile of periovarian fat. (Source: Journal of Animal Physiology and Animal Nutrition)

Role of Eruca sativa L. seeds in boosting the reproductive performance of male Japanese quails (Coturnix c. japonica)
AbstractHerein we attempt to shed light on the potential improving effect ofEruca sativa seeds (ESS) on the reproductive aspects of male Japanese quails. To accomplish this objective, two groups of quails were supplemented with ESS powder at doses of 5 and 10  g/kg feed from 7 days to 140 days of age, in addition to the control group, which did not receive treatment. Forty males were reared singly in cages to evaluate sperm characters and 32 males were raised with 64 females to evaluate fertility and sperm penetrability. Sixty-six phytochemical compoun ds were found according to gas chromatography–mass spectrometry ana...
