The Effect of Birth Weight on Fattening Performance, Meat Quality, and Muscle Fibre Characteristics in Lambs of the Karayaka Native Breed.

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 the lambs into three distinct groups based on birth weight: low birth weight (LBW), medium birth weight (MBW), and high birth weight (HBW). Throughout the fattening phase, the lambs were given access to food and water, culminating in the slaughter at the end of the study.

Review of sheep breeding and genetic research in Türkiye.

The livestock industry in Türkiye is vital to the country's agricultural sector and economy. In particular, sheep products are an important source of income and livelihood for many Turkish smallholder farmers in semi-arid and highland areas. Türkiye is one of the largest sheep producers in the world and its sheep production system is heavily dependent on indigenous breeds.

Fatty acid and conjugated linoleic acid content of Anatolian buffaloes at different muscle types and slaughter weight.

This research was performed to detect tissue fatty acid (FA) composition and conjugated linoleic acid (CLA) content in Anatolian buffaloes at different muscle types (MTs) and slaughter weights (SWs). The research was carried out on a private commercial livestock farm in Tokat. The research's animal material comprised 20 Anatolian buffalo calves with approximately 100 kg body weights, weaned at about 150 days of age.

Fatty acid profilies and some meat quality traits at different slaughter weights of Brown Swiss bulls.

This research was done to detect some meat quality traits and tissue fatty acid combination of the longissimus dorsi thoracis (LT) muscle of Brown Swiss bulls at the different slaughter weights (SW). The animal material of the study comprised 20 Brown Swiss bulls. In the study, Brown Swiss bulls were divided into two groups according to their SW as low (LSW (n = 10); 431-503 kg) and high (HSW (n = 10); 504-583 kg).

The effect of different slaughter weights on some meat quality traits of musculus longissimus dorsi thoracis of male Anatolian buffaloes.

This research was performed to examine the effects of different slaughter weights (SWs) on some meat quality traits of Anatolian Buffaloes (n = 20). Weaned 5-month-old Anatolian Buffalo calves with an average live weight of 100 kg were used as the animal material of the study. Experimental calves were randomly divided into four different slaughter weight groups 200 kg (SW-1: n = 5), 250 kg (SW-2: n = 5), 300 kg (SW-3: n = 5), and 350 kg (SW-4: n = 5).

Meat production characteristics of Turkish native breeds: II. meat quality, fatty acid, and cholesterol profile of lambs.

The study conducted a comparison of meat quality, fatty acid profile, and cholesterol amounts of longissimus dorsi (LD) and semitendinosus (ST) muscles of male lambs born to Turkish indigenous sheep breeds raised under intensive conditions. A total of 36 singleton male lambs were used as experimental animals of the Akkaraman (A), Morkaraman (M), Awassi (IW), Karayaka (KR), Kıvırcık (KV), and Middle Anatolian Merino (MAM) pure breeds. All lambs were fed the same diet until they reached a target weight of 40 kg weight.

Some gastrointestinal tract characteristics of Karayaka ram lambs slaughtered at different weights.

Thirty-one Karayaka ram lambs were slaughtered at different body weights (30 (n =  7), 35 (n =  6), 40 (n =  7), 45 (n =  6), and 50 (n =  5) kg of body weight at fast) to evaluate the growth of their gastrointestinal tract (GIT) characteristics, to determine the relationship among slaughter body weight (SBW) and empty body weight (EBW), whole GIT and segments, and the influence of slaughter weight on the pH of rumen, jejunum, and cecal contents. The effects of the SBW on GIT weight (P <  0.05), stomach (P <  0.

Estimates of (co)variance components for direct and maternal effects on birth weight of Karayaka lambs.

The purpose of this study was to estimate the genetic parameters for birth weight of Karayaka lambs by separating direct genetic, maternal genetic, and maternal permanent environmental effects. Records of 1013 Karayaka lambs born between 2005 and 2010 were analyzed. Six different animal models were examined, all including direct additive genetic variance and various combinations of genetic and environmental maternal effects.

Fattening performance, slaughter, carcass and meat quality traits of Karayaka lambs.

In order to verify the fattening performance, slaughter and carcass characteristics and to investigate the changes in some meat quality traits of Karayaka lambs weaned at 3 months of age, 39 lambs (23 males and 16 females) were used as experimental animals. The lambs were fed a concentrate mixture and alfalfa hay (120 and 168 g crude protein and 2,700 and 1,951 ME/kg, respectively) for a period of 60 days of fattening period. Male lambs were superior (p < 0.

Introducing the Karayaka sheep breed with its traits and influencing factors.

This study was planned to express the detailed traits of Karayaka sheep reared in Tokat province, also influencing factors on the traits were evaluated. While year effect was significant on 8 weeks weight, scanning weight, fat depth and muscle area, all the evaluated traits including birth weight and muscle depth were significantly affected by season (p < 0.05).
