Evaluation of minimally invasive estrus synchronization protocols in brown brocket deer (Subulo gouazoubira)
This study aimed to evaluate minimally invasive protocols for estrus synchronization in the brown brocket deer (Subulo gouazoubira). Females were submitted to Latin square design, in different treatments. All females received 0.25 mg of estradiol benzoate on the first day of treatment, concomitant with one of the following sources of progesterone: (1) DIP: an intravaginal progesterone releasing device for eight days, (2) MGA1x: once a day (in the morning) oral dose of 1 mg melengestrol acetate for eight days, (3) MGA2x: twice a day (morning and afternoon) oral doses of 0.5 mg of MGA for eight days, (4) P4LA: a single i.m. ...

Effect of endo ‐1,4‐beta‐xylanase supplementation to low‐energy diets on performance, blood constituents, nutrient digestibility, and gene expressions related growth of broiler chickens
AbstractThe presence of soluble and insoluble non-starch polysaccharides (NSP) was reported to reduce nutrient utilisation, and adversely impact the broilers ’ growth performance; accordingly, NSP-degrading enzymes are essential supplements to cereal-based diets. Therefore, the current trial was conducted to characterise the impacts of supplemental xylanase (Xyl) to diets with low-ME levels on performance, carcass traits, blood parameters, nutrient dig estibility and some genes expressions in broiler chickens. A total of 600 1-day-old Ross 308 male broiler chicks were randomly assigned to 6 treatments with 10 replication...

The role of phytogenic feed additives in stress mitigation in broiler chickens
AbstractThe increase in global temperature and consumers' welfare has increased the use of phytogenic feed additives (PFA) to mitigate the negative effects of heat stress on chickens in recent years. Various bioactive compounds capable of improving the thermotolerance of broiler chickens during exposure to thermal challenges have been identified in different plant species and parts. This review is an overview of the roles of bioactive compounds of different PFA, such as polyphenols and flavonoids, antioxidants, growth-promoting and immune-modulating agents, in heat stress management in broiler chickens. Common PFA in use, ...

Third-party intervention and post-conflict behaviour in agonistic encounters of pigs (Sus scrofa)
Third-party interference in agonistic contests entails a deliberate intervention in an ongoing fight by a bystanding individual (third party) and may be followed by post-conflict social behaviour to provide su... (Source: Frontiers in Zoology)

Body mass is associated with hibernation length, body temperature, and heart rate in free-ranging brown bears
Despite centuries of research, debate remains on the scaling of metabolic rate to mass especially for intraspecific cases. The high variation of body mass within brown bears presents a unique opportunity to st... (Source: Frontiers in Zoology)

Integrating Complex Life Cycles in Comparative Developmental Biology
Annu Rev Genet. 2023 Aug 16. doi: 10.1146/annurev-genet-071719-020641. Online ahead of print.ABSTRACTThe goal of comparative developmental biology is identifying mechanistic differences in embryonic development between different taxa and how these evolutionary changes have led to morphological and organizational differences in adult body plans. Much of this work has focused on direct-developing species in which the adult forms straight from the embryo and embryonic modifications have direct effects on the adult. However, most animal lineages are defined by indirect development, in which the embryo gives rise to a larval bo...

Ovary organization and ultrastructure in six species of Amynthas and Metaphire earthworms (Annelida, Crassiclitellata, Megascolecidae)
We present the ultrastructural details of germline and somatic cells. We propose the term "Amynthas" type of ovaries for this ovary organization. We suppose that such ovaries are characteristic of other megascolecids and related families.PMID:37586295 | DOI:10.1016/j.zool.2023.126109 (Source: Zoology)

A systematic review of mammary gland inflammations in queens (Felis catus)
Anim Reprod Sci. 2023 Aug 12;256:107318. doi: 10.1016/j.anireprosci.2023.107318. Online ahead of print.ABSTRACTMastitis is a rare condition that can be diagnosed in female cats of all breeds and ages. It is usually caused by bacterial agents and is frequently encountered secondarily in feline mammary fibroepithelial hyperplasia (FEH). If left untreated, it can peril both the queen and her kittens. Therefore, a reliable and quick diagnosis is the primary key to successful treatment. Conventional diagnosis consists of a clinical and ultrasound evaluation of the queen's mammary glands. However, there is a lack of literature s...
