ABSTRACT Prediction of body weight (BW) using biometric measurements is an important tool especially for animal welfare and automatic phenotyping tools that needs mathematical models. In this study, it was aimed to predict the BW length (BL), chest girth (CG) width waist (WW) rabbits maternal form Hyla NG. The standard rabbit‐raising practices were applied animals. A highly efficient gradient‐boosting decision tree (LightGBM), eXtreme (XGBoost) support vector machine (SVM) algorithms...
The aim of this study is to evaluate the model performance in classification FAMACHA© scores using Support Vector Machines (SVMs) with a focus on estimation scoring system used for early diagnosis and treatment management parasitic infections. are color-based visual assessment determine parasite load animals, study, accuracy was investigated. model's rate analyzed detail metrics such as sensitivity, specificity, positive/negative predictive values. results showed that had high sensitivity...
The study conducted a comparison of meat quality, fatty acid profile, and cholesterol amounts longissimus dorsi (LD) semitendinosus (ST) muscles male lambs born to Turkish indigenous sheep breeds raised under intensive conditions. A total 36 singleton were used as experimental animals the Akkaraman (A), Morkaraman (M), Awassi (IW), Karayaka (KR), Kıvırcık (KV), Middle Anatolian Merino (MAM) pure breeds. All fed same diet until they reached target weight 40 kg weight. After feeding period,...
Maternal nutrient intake during early- and mid-gestation can alter fetal growth development with long-term consequences on the postnatal productivity health of offspring. The aim this study was to investigate effects maternal nutrition level rate, carcass composition, muscle fibre characteristics meat quality in lambs. Ewes were fed from Days 30 80 gestation as follows: 100% (control group, C), 50% (undernutrition, UN) or 175% (overnutrition, ON) their daily requirement. During rest...
Anatolian buffalo is an important breed reared for meat and milk in various regions of Türkiye. The present study was performed to estimate body weight (BW) from several measurements, such as tail length (TL), shoulder height (SH), withers (WH), (BL), chest circumference (CC), shank diameter (SD) birth (BiW). data set taken Muş Province In this respect, 171 buffaloes were used. To the BW, different proportions training test sets used with MARS algorithm. optimal determined at a proportion...
The current study aimed to predict final body weight (weight of fourth months age select the future reproducers) by using birth weight, type, sex, suckling at weaning and for Romane sheep breed. For this purpose, classification regression tree (CART), multivariate adaptive splines (MARS), support vector machine (SVR) algorithms were used training (80%) testing (20%) sets. Different data mining learning 393 (238 female 155 male animals) with different artificial intelligence algorithms. best...
The aim of the present study was to determine effect estrus synchronization programmes on parturition time and some reproductive characteristics Saanen goats. Estrus goats synchronized as follows: by use intravaginal sponges containing 30 mg flugestone acetate for 11 days following IM injection 500 IU PMSG (group PP; n = 80) or only P; natural (control; C, 50). Forty-eight hours after removing sponges, all were introduced bucks. Kidding rate litter size in PP group higher than those C P...
Placental characteristics are the most important indicators of fetal growth and development that influence kid vitality. The aim this study was to examine effect maternal parity on placental birth-related traits in Saanen goats. experiments were conducted 41 singleton-bearing does, ranging from 1 4 years age classified according first, second, third parities. Birth weight, efficiency, cotyledon density influenced by (P < 0.05). First-parity does had kids with significantly 0.05) lower birth...
The effect of maternal nutrition level during the periconception period on muscle development fetus and maternal-fetal plasma hormone concentrations in sheep were examined. Estrus was synchronized 55 Karayaka ewes either fed ad libitum (well-fed, WF, n=23) or 0.5×maintenance (under-fed, UF, n=32) 6 days before 7 after mating. Non-pregnant (WF, n=13; n=24) carrying twins n=1) female n=1; n=3) fetuses removed from experiment. singleton male well-fed (n=8) under-fed (n=5) collected day 90...
There is little knowledge about the carcass potential of Turkish native goat breeds raised under different rearing conditions. It necessary to compare characteristics these minimize effect Therefore, this study aims growth, slaughter, and male kids at weaning age eliminate impact Kids born Angora (n = 6), Hair Honamlı Kilis 6) breeds, ranging in from 2-3 years, were slaughtered 90 days determined immediately. differences (p < 0.05) among terms birth weight (BW) daily gain (DWG) age. had...
This investigation aimed to assess the influence of birth weight on post-weaning fattening performance, meat quality, muscle fibre characteristics, and carcass traits in Karayaka lambs. The study categorized lambs into three distinct groups based weight: low (LBW), medium (MBW), high (HBW). Throughout phase, were given
Objective The aim of this study was to compare the effects 36.5°C and 38.5°C incubation temperatures on maturation bovine oocytes developmental competence embryos. Methods In experiment 1, were maturated in bicarbonate-buffered TCM–199 for 22 hours a humidified atmosphere 5% CO2 air at either or nuclear status determined. 2, vitro fertilized allocated randomly into synthetic oviductal fluid medium with without mixture 1 mM L-glutathione reduced 1,500 IU superoxide dismutase cultured CO2, O2,...
Abstract. The aim of this study was to determine growth performance, carcass and meat quality Karayaka female lambs born in different seasons. Winter (breeding season; n=15) autumn (out the breeding singleton were used study. Birth slaughter weights both groups similar, but weaning weight higher (P<0.05). had lower yield, lung, spleen gastrocnemious muscle (P<0.05), liver, kidney, empty reticulo-rumen, small intestine, internal fat, suprarenal fat a thickness over longissimus dorsi...
Selection of dairy cattle for higher milk yield, without considering important non-production traits, has decreased reproductive efficiency. Thus, low performance is a major problem in high yielding cattle. Previous studies showed that dietary manipulation to improve fertility holds much promise and fats have positive effects on functions Positive due the fatty acids, which are precursors progesterone prostaglandins. Progesterone prostaglandins hormones most factors play role control...
In the current paper direct additive and maternal genetic effects on birth, weaning (at 90 days of age), scanning 20 weeks age) weights muscle fat depths ribeye area in Karayaka lambs were investigated. Analyses carried out by restricted maximum likelihood approach, fitting 6 animal models with various combinations effects. The best model was chosen after testing for improvement log-likelihood values. Direct heritability (h2d) all traits decreased when included models. (h2m) ranged from 0.15...
The aim of the study was to evaluate body condition score (BCS) and somatic cell count (SCC) milk in Turkish Saanen goats. Data were obtained from 95 goats during morning milking. While a 1–5 scale used assess BCS, direct microscopy performed analyse SCC. Effect stage lactation (SL) number kids at birth (NK) evaluated three subgroups. SL has not affected parameters, with single kid had significantly higher BCS (P < 0.05) than twins. Correlation coefficient between parameters estimated as...
Sheep farmers’ perceptions of climate change and its impacts the adaptation strategies they consider to address these risks are great importance in ensuring resilience farming practice. This study focused on sheep perception actions taken mitigate impacts. A total 68 surveys were carried out among farmers (39 transhumance 29 semi-intensive farmers) by two different representative production systems Türkiye. Variables regarding socio-economic profile, impacts, identified analyzed. Principal...
The aim of this study was to classify placental characteristics Akkaraman, Morkaraman, Karayaka, Awassi, Malya, and Bafra sheep breeds using the hierarchical clustering method. In total, 240 individual data records were used as experimental material. Placental such total cotyledon surface area, small large length, depth, etc. explanatory variables breeds’ characteristics.
