Abstract
House sparrow is a globally adaptive bird. The way this creature adapted to all areas of the world, having different selection pressures, is interesting to understand. The present study is focused on seasonal changes, having different selection pressures and how it is adapted to these changes and whether hematological flexibility plays a role in this success. House sparrow's adaptations in the same area, during different seasons, have been studied in a sub-tropical area, Potohar, Pakistan. We used hematological parameter analysis for this purpose. Blood samples were collected from Sparrows in winter, spring, and summer and analyzed for some hematological parameters. White blood cells (WBCs) were higher in spring and summer which may relate to mating promiscuity. Sparrows were more stressed in summer. The Red blood cells (RBCs) and hematocrit (Hct) were greater in summer. Mean corpuscular volume (MCV) is lower in summer. This may have an adaptation to cope with high stress in summer as small-size RBCs increase gaseous exchange. Platelets were not affected by season or gender. Mean corpuscular volume and Mean corpuscular hemoglobin (MCH) are positively correlated with each other. Red blood cells, hemoglobin (Hb) and MCV were higher in males during the spring season perhaps as an adaptation to energetic activities during spring like mating calls and search for nesting sites. White blood cells remained the same in both genders in summer and winter, and effected in spring may be related to the mating system. Behavioral state is linked with physiological states that shows tradeoff and life history traits. This study is a small effort to know this incredible species. We can work further in different parts of the world to explore different aspects of it.

Effects of Animal Welfare-Certified Rearing Systems on the Blood Parameters and Meat Quality Characteristics of Broilers at the Farm Level in Korea. Food Sci Anim Resour 2022; 42:128-141. [PMID: 35028579 PMCID: PMC8728506 DOI: 10.5851/kosfa.2021.e68] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Revised: 11/23/2021] [Accepted: 11/30/2021] [Indexed: 11/21/2022] Open
Abstract
Compared to the conventional farms (CF) rearing of broilers, the rearing
management of animal welfare-certified farms (AF) must provide low stocking
density, perch, air regulation, and feeding plant-based protein. This study
aimed to compare the effects of rearing management in CF and AF on blood
parameters, meat quality, and bioactive compound content in Ross 308 broiler
chickens at the farm level before transportation to slaughterhouses. Blood and
meat samples were obtained at 28-35-day-old chickens from three CF and three AF.
In blood samples, low-density lipoprotein cholesterol (p<0.05),
triglyceride (p<0.001), glucose (p<0.01), total protein
(p<0.001), albumin (p<0.01), and white blood cell (p<0.001)
levels as well as the heterophil/ lymphocyte ratio [stress index (SI),
p<0.001] were lower in broilers from AF than in CF. In meat samples,
shear force (p<0.001, p<0.05), and carnosine contents
(p<0.001, p<0.05) in both breast and thigh meat from AF were
higher than those in meat from CF. The contents of linoleic acid
(p<0.001), α-linolenic acid (p<0.001), and eicosapentaenoic
acid (p<0.05) were higher in the samples from AF than those from CF. This
study reveals that such differences are influenced by the different rearing
factors in nutrition, housing, and management practices between CF and AF.
Supplementation of plant-based protein and enough space to move due to lower
stocking density accounts for the large differences between them. These results
can be used as preliminary data showing that the AF system reduces the SI and
enhances carnosine and polyunsaturated fatty acids levels in chicken meat at the
farm level before transportation.
