Environmental factors influencing milk yield and lactation length in Italian Mediterranean buffaloes in Türkiye

This study was conducted to investigate the effects of the environmental factors including, birth season, lactation number, age, and service period, on the annual average lactation milk yield and lactation period of the Italian Mediterranean Buffaloes that were milked by rotary milking systems. The research was carried out on the data of 347 buffaloes in a modern dairy farming between 2016 and 2018 years. Their annual average lactation milk yield and lactation period were found to be 1587.55 ± 33.82 L and 247.66 ± 4.39 days. It was observed that the prolonged service period had a positive effect on the total lactation milk yield and lactation period. The season did not affect the lactation milk yield, but the lactation period was longer in the buffaloes calving in winter months. The service period has a direct effect on the economic profitability, and it was observed that the service periods of buffaloes calving in winter was shorter. It was also determined that milk productivity was positively affected due to the increase in age and lactation number, but there were wide variations in the herd. In conclusion, age, lactation number, and service period were efficient on the annual average milk yield and lactation period, but, on the other hand, the season did not affect the annual average milk yield. More breeding studies are required to minimize variations in buffalo herds milked by different milking techniques.   

Environmental factors influencing milk yield and lactation length in Italian Mediterranean buffaloes in Turkiye

This preliminary study was conducted to investigate the impact of the fixed effects of calving season, parity, calving age and service period, on the annual average milk yield and lactation length of the Italian Mediterra-nean Buffaloes that were milked by rotary milking parlor. For this purpose the data of 347 buffaloes of a dairy farm (with milking parlor) was used. Their annual average milk yield and lactation length were found to be 1587.55 +/- 33.82 L and 247.66 +/- 4.39 days. It was observed that the prolonged service period had a positive effect on the total milk yield and lactation length. The calving season did not affect the milk yield, but the lactation length was longer in the buffa-loes calving in winter months. The service period had a direct effect on the economic profitability, and it was observed that the service period of buffaloes calving in winter was shorter. It was also determined that milk productivity was positively affected due to the increase of calving age and parity, but there were wide variations in the herd. In conclu-sion, calving age, parity, and service period had a positive effect on the annual average milk yield and lactation length, but, on the other hand, calving season did not affect the annual average milk yield. Further studies on breeding and herd management are required to minimize variations in buffalo herds milked by rotary milking system

Östrus senkronizasyonu uygulanan saanen keçilerinde üreme özellikleri ve oğlaklarda büyüme özelliklerinin belirlenmesi]

This study aimed to determine the reproductive characteristics of Saanen goats of Australian origin using an estrus synchronization program with hormones (MPA and PMSG) in two different mating periods (Period I and Period II) and to investigate the survival rates and growth performances of kids. According to the results of the research, it was determined that pregnancy rate and litter size were higher in the mating period I (87% and 2.16) compared to mating period II (80.5% and 2.03), and it is hypothesized that this situation is related to the length of dry period of the goats. Although the mortality rate (P0.05). These results indicate that the kidding season should be an environmental factor to be taken into account when planning the production. In addition to this, it is important to optimize the care and management conditions, especially during the kidding season, due to the high multiple birth types for the estrus synchronization program in Saanen goats

Comparison of Growth and Development Characteristics of Hair and Damascus Kids Reared under Extensive Conditions

The present study aimed to compare the growth and the development of Hair and Damascus kids reared under extensive conditions. The body weights of Damascus goats were significantly higher than that of the Hair goats during the 360 days growth period (P < 0.05; P<0.001). Body weight was influenced by birth type only at birth and on the 360th day of the growth period, and single-birth kids had higher values than twin-born kids (P < 0.05). Exceptfor the 120th day of the growth period, the body weight of kids born in dam age group III was higher than that of kids born in the other dam age groups (P < 0.05; P < 0.01; P < 0.001). The breed effect was markedly observed after the 120th day of the growth period concerning body measurements especially chest depth, rump height, and body length. Damascus goats were significantly higher than that in the Hair goats for these traits (P < 0.001). It can be suggested that comparative studies containing the entire growth period should be conducted on other indigenous goat breeds (Angora, Honamlı, Kilis, and Norduz goat breeds) and to demonstrate the growth and development characteristics of these breeds

Genetic Animal Heritage of Anatolia: Short-beaked Pigeon Genotypes

This study aimed to determine the morphological and morphometric characteristics of Bango, Mısıri and Baska pigeons, which have been preferred to breed as ornamental and diver pigeons in Anatolia. The ages of the pigeons were classified into four groups: 12-24 months of age (age group I), 25-36 months of age (age group II), 37-48 months of age (age group III), and 48 months of age and over (age group IV). These three pigeon genotypes were included in the bird group with short beak and small body structure. There were statistically significant differences among the genotypes in terms of body weight, head length-width, beak length-depth, chest depth-width, thoracic perimeter, tail and body length, wing span-length, tarsus diameter (p?0.01). Considering the body plumage color of pigeons, Mısıri and Bango pigeons show more similar appearance, however Baska pigeons has a different appearance from both genotypes. However, it is thought that it would be appropriate to evaluate morphological data together with genetic analysis. We think that these three pigeon genotypes should be taken under immediate protection in order to protect the domestic gene resources of Turkey.

The morphological and morphometric characteristics of Alabadem pigeons

This study aimed to determine the morphological and morphometric characteristics of Alabadem pigeons, which are grown as ornamental pigeons in Edirne province, and to determine mutual traits with other indigenous pigeon breeds in Turkey by comparing with previous studies. Body weight (P < 0.001), head length (P < 0.01), head width (P < 0.05), beak length (P < 0.001), and tarsus diameter (P < 0.05) of age group III were higher than those of other age groups; however, the wingspan of age group II was greater than that of other age groups in Alabadem pigeon. Compared to other indigenous genotypes in Turkey, the Alabadem pigeon is a small-sized genotype. Alabadem pigeons were similar to Edremit butterfly pigeons and Thracian tumbler pigeons in terms of crested and blackeyed pigeons. On the other hand, the irregularly shaped mark (almond) on the head in Alabadem pigeons was similar to the wide-long irregular shaped mark on the neck of Edremit butterfly pigeons. Some basic plumage colors (black, yellow, and red) and intermediate colors (chickpea and scarlet) were identical to Alabadem pigeons and Thrace roller pigeons. Since Alabadem pigeons have many mutual characteristics with Edremit butterfly pigeons and Thracian roller pigeons, genetic studies may be recommended to determine the degree of relationship among these breeds.Tekirdag Namik Kemal University Scientific Research Project Coordination Unit [NKUBAP.10, 17.138]This study was funded by Tekirdag Namik Kemal University Scientific Research Project Coordination Unit (Project No: NKUBAP.10.GA.17.138)

Türkiye?in yerli gen kaynağı, muradiye dönek güvercinlerinin morfolojik özellikleri]

This study was conducted to investigate the morphological characteristics of Muradiye Dönek pigeon. It is a local animal genetic resource and cultural heritage and has an important place among the genotypes of domestic pigeons in Turkey. The animal material of this study consisted of 100 pigeons (50 females and 50 males) from seven pigeon enterprises. In the study, morphological characteristics were evaluated and morphometric measurements were determined. Body plumage colors of pigeons were determined as black (70%), red (16%) and blue (14%) galaca. In some birds, the yellow beaks and nails may bear black spots, which pigeon breeders refer to as ‘zikir’. The term ‘biyik’ (mustache) is used when black feathers appear among the white feathers on the head, and the term ‘kemer’ (belt) is used when black feathers appear in the tail. The differences between the mean values of body weight and wingspan (P<0.001), chest depth (P<0.05) values were statically significant for age groups, which were reported to affect flight characteristics in birds. As a result, when the morphological characteristics obtained in Muradiye Dönek pigeons are compared with other researchers, it is thought that the selection of these birds were carried out by the breeders in terms of the game behavior such as rotation movement during the diving and landing. Although the data obtained in the study support the hypothesis that Muradiye Dönek pigeons should be defined as a different breed, further studies with DNA analysis are required to confirm this situation. © 2021, Chartered Inst. of Building Services Engineers.

Correlation between live weight and body measurements in certain dog breeds

The purpose of this study was to determine the correlation between live weight and body measurements in Zagar, Zerdava, and Catalburun dogs. Animal materials were obtained from various regions of Turkey. A total of 304 dogs from three breeds were used: Zagar (45 females, 59 males), Zerdava (50 females, 50 males), and Catalburun (62 females, 38 males). Live weights and certain body measurements were determined. A linear regression model was created using the parameters obtained in this study. The bodyweights calculated with the body measurements were found to be at a high or acceptable level in the Zagar, Zerdava, and Catalburun genotypes (R-2 = 0.902, 0.467, and 0.697, respectively).Scientific and Technological Research Council of Turkey (TUBITAK)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK)The authors would like to thank Scientific and Technological Research Council of Turkey (TUBITAK) and the owners of the Zagar, Zerdava and Catalburun dogs for their support to the project

Biogas Production And Utilization

Nüfus artışı, sanayileşme ve şehirleşme ile birlikte yakıt için kullanılan rezervlerinin azalması insanları farklı enerji kaynaklarını bulmaya yönlendirmiştir. Bu kaynaklardan biri olan biyogaz, insan sağlığı için tehdit oluşturan organik atıkların elektrik ve ısı enerjisine dönüştürülmesine yardımcı olmakta ve çevreye daha az zarar vermektedir. Gelişmiş ve gelişmekte olan ülkelerde tarım ve hayvancılıkta yaygın olarak kullanılan biyogaz üretim tesislerinin sayısı, Türkiye'de istenilen düzeye ulaşmamıştır. Bu tesisler, daha çok belediyelerde evsel ve gıda sanayisi atıklarının değerlendirilmesi amacıyla kurulmuştur. Bu çalışma yetiştiricilerin, sürü yönetiminde önemli bir problem oluşturan atıkların yok edilmesi ya da tekrar kullanılmasını sağlayan ve alternatif enerji kaynağı olarak görülen biyogaz üretim tesisleri hakkında bilgilendirilmesi ve bu alandaki olanakların araştırılması amacıyla yapılmıştır. Ayrıca Türkiye'deki hayvancılık işletmelerinde biyogaz ünite sayısının arttırılması ile ülke çapında karlılığın arttırılacağı düşünülmektedir.Population growth, industrialization and decline of utilizable energy reserves in the world led people to search for different sources of energy. One of this sources known as biogas. It helps to convert organic wastes that damaging human health to electricity and heat energy makes less damaging to the environment. Biogas facilities are widely used by developed countries and developing countries in agriculture and animal husbandry which is not reach the desired level in Turkey. The purpose of this facilities was utilized the household and food industry wastes in municipal governments. The aim of this study was to conduct of the breeders for biogas production facilities that seen as an alternative energy source for eradicate or reutilize the waste disposals in which constitute a major problem in herd management and to investigate of the potential opportunities in this field. Increasing the number of biogas facilities of livestock enterprises in Turkey possibly increased profitability all over the countr
