    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

    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

    An Empirical Investigation of the Spillover Effects of Advertising and Sales Promotions in Umbrella Branding

    Get PDF
    The authors investigate and find evidence for advertising and sales promotion spillover effects for umbrella brands in frequently purchased packaged product categories. The authors also capture the impact of advertising (as well as use experience) on both utility mean and variance across two categories. They show that variance of the random component of utility declines over time on the basis of advertising (and use experience) in either category, This constitutes the first empirical evidence for the uncertainty-reducing role of advertising across categories for umbrella brands

    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.

    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.

    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)

    The Impact of Brand Quality on Shareholder Wealth

    Get PDF
    This study examines the impact of brand quality on three components of shareholder wealth: stock returns, systematic risk, and idiosyncratic risk. The study finds that brand quality enhances shareholder wealth insofar as unanticipated changes in brand quality are positively associated with stock returns and negatively related to changes in idiosyncratic risk. However, unanticipated changes in brand quality can also erode shareholder wealth because they have a positive association with changes in systematic risk. The study introduces a contingency theory view to the marketing-finance interface by analyzing the moderating role of two factors that are widely followed by investors. The results show an unanticipated increase (decrease) in current-period earnings enhances (depletes) the positive impact of unanticipated changes in brand quality on stock returns and mitigates (enhances) their deleterious effects on changes in systematic risk. Similarly, brand quality is more valuable for firms facing increasing competition (i.e., unanticipated decreases in industry concentration). The results are robust to endogeneity concerns and across alternative models. The authors conclude by discussing the nuanced implications of their findings for shareholder wealth, reporting brand quality to investors, and its use in employee evaluation

    A Dynamic Analysis of Market Structure Based on Panel Data

    No full text
    Internal market structure analysis infers brand positions in an attribute space from preference and choice data, given a market in which consumers have heterogeneous tastes for attributes. Previous market structure models have adopted a static framework (e.g., Elrod 1988, Chintagunta 1994, Elrod and Keane 1995). Furthermore, they assumed that consumer perceptions of brand attributes do not vary across consumers. Yet, these approaches may render inaccurate representations of market structure if there is state dependence in consumer choice behavior. This paper attempts to incorporate consumer choice dynamics into market structure models by specifying the source of choice dynamics explicitly. In particular, the process by which past purchases affect current choices is modeled in a framework which captures both consumer habit persistence and variety seeking behavior. More specifically, consumer preferences for brand attributes are modeled to depend on the attributes of brands bought on the previous purchase occasion. Furthermore, the modeling approach adopted incorporates heterogeneity in both consumer preferences and perceptions of brand attributes. The audience of this paper includes practitioners and academics interested in understanding consumer choice processes and inferring market structure from consumer choice data. The proposed models are estimated on Nielsen scanner panel data for margarine, peanut butter, yogurt, and liquid detergent using simulated maximum likelihood techniques. The empirical results suggest that accounting for choice dynamics improves both in-sample and out-of-sample fit. The results indicate that the average consumer is habit persistent in all the product categories studied. This result is consistent with the findings of Kannan and Sanchez (1994), who conducted an aggregate analysis of consumer variety seeking behavior across product categories. However, the results obtained in this paper suggest that consumers are heterogeneous with respect to the processes by which past purchases affect current purchases. These results provide strong evidence for habit persistence and variety seeking in brand attributes to be the behavioral source of consumer choice dynamics in food categories. Thus, consumer tastes (utility weights) seem to be affected by the attributes of the brands consumed in the past. Given the empirical result that a large proportion of consumers are habit persistent, this suggests that tastes are reinforced by the brand attributes consumed in the past. The empirical results also show that not accounting for state dependence in market structure models for panel data may produce misleading results, that is, depending on consumer behavior patterns, models that do not account for state dependence may distort the true nature of competition among brands. More specifically, the results confirm the expectation that if there is habit persistence, that is, if consumer tastes are reinforced by attributes of brands consumed in the past, models that do not capture this choice dynamics will overestimate the distance between (similar) brands. Furthermore, the policy experiments conducted suggest that (1) static models overestimate the short-run impact of a price cut on the sales of the brand on promotion, (2) price cuts hurt the sales of the more similar brands more, and (3) free samples affect relatively less similar brands the most. Finally, this paper studies variety seeking and habit persistence across brands over purchase occasions. However, variety seeking behavior may also involve the purchase of a portfolio of brands or items at a purchase occasion. Consumers may buy multiple items knowing that prior to the next trip they may want to consume different items (Simanson 1990, Walsh 1995). This type of behavior can be modeled within the context of dynamic expected utility maximization with forward-looking consumers. The development and estimation of market structure models that include forward-looking consumers who maximize expected-utility over a planning horizon, incorporating their future tastes and needs, and shopping for an inventory of brands, remain an important future research issue.brand choice, buyer behavior, econometric models, market structure
