ABSTRACT The study evaluates the influence of environmental enrichment on behavior, leucometry, and performance of commercial pigs. Thirty-two hybrid pigs (Landrace × Large White × Pietran), at 69 days of life, were divided into four groups and subjected to different environmental stimuli: concrete floor, with no enrichment (C); floor bedding with wood chips (CM); concrete floor, with mobiles (MO); floor bedding with wood chips and the presence of mobile (CM + MO). The study collected behavioral data of the animals […]

ABSTRACT The objective of this study was to assess the effect of Suanzaoren decoction on stress response of horses in transportation. A total of six male Ili horses were equally divided into Suanzaoren decoction treatment group (n = 3; basal diet supplemented with Suanzaoren decoction, three times/day) and control group (n = 3; basal diet, three times/day). After feeding for five days, all horses were transported for 8 h to simulate stress. Blood and serum samples were obtained before transport […]

ABSTRACT The objective of this study was to identify differentially expressed genes (DEG) between females and males in early bovine embryos. Superovulated cattle (n = 4) in the age span of 16–18 months were artificially inseminated with semen from the same bull that has been proven to be fertile. Blastocysts were collected by routine non-surgical uterine flushing on day 7 after insemination. This study determines the sex of embryos using a micro-injection pipette to collect a few blastomeres through the […]

ABSTRACT This study aimed to evaluate the effects of sunflower meal (SFM) inclusion on the performance, nutrient digestibility, and respirometric parameters in sheep. Twenty-four Dorper × Santa Inês uncastrated males, with an average age of 5 mo and initial body weight (BW) of 27.91±6.0 kg, were distributed in a randomized block design with four treatment diets containing 0, 100, 200, and 300 g of SFM/kg of total dry matter, replacing soybean meal. Intake, weight gain, ingestive behavior, and in vitro […]

ABSTRACT The objective of this study was to investigate the effect of cottonseed peptides from in vitro degradation with protease, Enterococcus faecalis ( E. faecalis ), or both on the growth performance, nutrient digestibility, and health status of pigs. We used four diets containing non-degraded, protease-degraded, E. faecalis -degraded, or both-degraded cottonseed meal at 20% for growing phase (6 wk) and 16% for finishing phase (7 wk), corresponding to barrows, with six replicates of six pigs each. Results showed that […]

ABSTRACT The objective of this study was to spatially estimate the technical efficiency of sheep farms and explore the factors affecting the technical efficiency. Research data were collected randomly from 328 selected sheep farms in Ankara, Antalya, Diyarbakir, Konya, Mersin, and Sanliurfa provinces in Türkiye. The meta-frontier technical efficiencies (MTE) were estimated by using a stochastic meta-frontier production model. The meta-frontier technology ratio (MTR) was used to calculate the distance from the individual frontier to the meta-frontier. The determinants of […]

ABSTRACT The objective of this study was to determine the impact of metabolic changes occurring in induced subclinical gestation toxaemia in ewes on metabolic parameters and vigour in the first 72 h of their lambs’ life. Fifty-one adult Corriedale ewes of known gestation date and fed on a natural pasture were randomly divided into four groups at day 145 of gestation. Group A (ewes with single pregnancies) and group C (ewes with twin pregnancies) were fed on a natural pasture […]

ABSTRACT The objective of this study was to evaluate the effects of cocoa meal in feed concentrate on the spermatogenesis in sheep. Twenty-five uncastrated males were divided into four groups and fed concentrated feed, supplemented with 0, 10, 20, and 30% cocoa meal, respectively, for 150 days. At the end of this period, the animals were slaughtered, the testicles were collected for histological slides, and testicular morphometric assessments were conducted, including cell type quantification in the seminiferous epithelium, intrinsic spermatogenesis […]

ABSTRACT The objective of this study was to evaluate whether the addition of different levels of capsaicin in the diet of female turkeys has beneficial effects on growth performance and the antioxidant and oxidant status in serum and meat. A total of 150 female turkeys were distributed in a completely randomized design with three treatments with five replicates per treatment and ten birds per experimental unit. Treatments were identified as control (without additive); T400 – basal diet containing 400 mg/kg […]

ABSTRACT The objective of this work was to assess the performance of two aeration types, splash and blower, used on a commercial biofloc technology (BFT) farm of red tilapia, Oreochromis sp., and their effect on growth performance and water quality parameters. For this, red tilapia juveniles were randomly distributed into twelve tanks. Each tank had an independent aeration system, and two experimental groups were characterized: six tanks used splash aerators (SPL group; one per tank, 1 hp), and the remaining […]
