Immunological capability shows a sexual dimorphism in diverse animal species. Females are generally more immunocompetent than males, leading to the higher susceptibility of males to infection compared to females and thus greater infection-related pathology in males. These sex-differences in...

Semen traits play the vital role in determining the fertility of a broiler breeder flock; however, it can be influenced by several factors. This experiment was carried out to assess some of these factors affecting the semen. A total of 89 male birds and 960 hens of 20-week-old broiler breeder (2215 ...

An experiment was conducted to study the effects of gender on weekly growth performance and nutrient utilization in broilers. Seventy two day old broilers were randomly allotted to 3 treatment groups, each having 4 replicates with 6 birds in each replicate. Diets were formulated as per ICAR 2013...

A study was assigned in 18 Gramasree male birds of 32nd weeks of age, randomly distributed to 3 experimental groups (G1, G2 and G3) with 6 birds in each group and housed separately in male cages for 91 days. During this experimental period, layer breeder ration (control) was prepared as per ICAR,...

Genetic selection for rapid growth in broilers has inadvertently resulted in increased susceptibility to heat stress, particularly in male birds. Increased oxidative stress associated with hyperthermia may be reduced by avian uncoupling protein (avUCP), which has been proposed to modulate free...

The gonadal activity of wild birds shows seasonal variation, and is regulated by the interaction between external environmental and internal hormonal factors. We Investigated in this short-term study, if temperature alters the stimulatory photoperiodic responses (growth-regression cycles in body...

Mycotoxins are secondary metabolites produced by pathogenic fungi under suitable environmental conditions. Moringa oleifera and vitamin E are known antioxidants and immunostimulants. In present experimental study, M. oleifera and vitamin E were administered in birds feed to mitigate the...

This study was carried out in Tando Allahyar district of Sindh, Pakistan to observe the phenotypic characterization of indigenous backyard poultry birds in Tando Allahyar. For this purpose, total 470 birds with 240 male and 230 females were brought under the study. Their phenotypic characteristics...

Both vitamin K and probiotics can promote the bone health of poultry and mammals. The present study was conducted to investigate the interactive effects between vitamin K₃ (VK₃) and Bacillus subtilis PB6 on the growth performance and tibia quality of broiler chickens with sex separate rearing. In a ...

Current experiment was planned to investigate the deleterious effects of the graded doses of aflatoxin B1 (AFB1) on white leghorn male birds. For this purpose, one-hundred birds of 8 weeks of age were divided into 4 equal groups and reared on feed contaminated with different doses of AFB1 for 10...
