Dairy cows enter the negative energy balance in the early post-partum period, which negatively affects milk yield, health status and reproduction. This study aimed to determine if milk yield (MY) and fat/protein (F/P) ratio could be used as reliable indicators for predicting the quality of aspirated oocytes and their further use for in vitro fertilisation. A secondary goal was to compare different periods before oocyte aspiration to determine which period had the most significant impact on the oocyte development in donor cows. All tested Holstein cows were at their first lactation (n = 68). The first ultrasound-guided follicular aspiration...

The aim of the study was to evaluate the effect of feeding regime (FR) and the combination of FR with pasture on the carcass composition and meat quality parameters of fast-growing chickens. Ross 308 chickens were split into three groups: Group 1 was fed ad libitum, and Groups 2 and 3 had a restricted diet. The chickens were feed-restricted at a rate of 70% ad libitum from 8 to 14 days of age. In Group 3, after restriction at the age of 21 days, chickens were kept on a pasture until the end of the experiment at 35 days of age. The chickens were fed ad libitum prior to and following restriction. Feed restriction and the combination...

Effect of thermal management on vitellogenesis and maturation in indoor-reared pikeperch (Sander lucioperca)Original Paper

Czech J. Anim. Sci., 2024, 69(1):18-28 | DOI: 10.17221/136/2023-CJAS  

The present study aimed to assess the effects of thermal manipulation on the vitellogenesis and final oocyte maturation (FOM) in pikeperch. Two groups of fish were stocked in two separate tanks of the climate chamber. One group was stocked at 10-month age (THERMAL), while the other was continually kept under stable photothermal conditions until 19-month-age (CONTROL) and then transferred to a climate chamber. The progress of vitellogenesis was assessed via evaluation of the oocyte diameter at the mid- and late-autumn phases, and the gonadosomatic index (GSI) at the late-autumn phase. Finally, females from the CONTROL group were hormonally stimulated...

Protective effects of green tea (Camellia sinensis) extract against cypermethrin-induced neurotoxicity in rainbow trout (Oncorhynchus mykiss) brain tissuesOriginal Paper

Corrigendum in: Czech J. Anim. Sci. 2024 May 31;69(5):209. doi: 10.17221/83/2024-CJASThis study was conducted to evaluate the protective impacts of green tea extract (GT) against cypermethrin-induced (CYP) neurotoxicity parameters such as acetylcholinesterase activity, oxidative stress, immune response, histopathology, apoptosis, and DNA damage in the brain tissues of rainbow trout (Oncorhynchus mykiss). The trial was divided into four groups (group 1, 2, 3 and 4). Group 1 was the control, while group 2 was treated with 0.1 mg/l of CYP, group 3 was treated with 0.1 mg/l of CYP + 100 mg/l of GT and group 4 was treated with...
