“…Broadly speaking, knobs tend to be more sizable in males compared to females, and they consistently exhibit greater dimensions in adults than in juveniles. ( Lee, 2021 ). Knob is not only a sign of sexual maturity of geese, but also one of the important packaging traits concerned by consumers.…”

The knob serves as both a sexual indicator of a goose’s maturity and a significant packaging attribute that garners consumer attention. However, studies regarding the morphological, anatomical and histological traits of different breeds and ages on the on knob in goose are lacking. In this study, six breeds with typical goose knob types were selected, and their knob size, morphological, anatomical and histological traits were characterized. The results showed that: Knob was more prominent in gander than in female goose, and the difference was the most obvious in Magang goose. Wanxi white goose and Shitou goose had the largest knob bulge, while Magang goose and Sichuan white goose were smaller. The total knob volume of Wanxi White goose and Shitou goose was significantly higher than that of other breeds, regardless of male or female (p < 0.05). The beak volume of Wanxi White goose and gander was significantly higher than that of other goose breeds (p < 0.05). Furthermore, the observation revealed that the “knob” primarily consisted of skin-derived tissue and bony protrusions. As age advances, the knob of both male and female geese undergoes synchronous development, with the knob of male geese typically surpassing that of their female counterparts during the same period. The growth rate of knob in male goose was the fastest from 70 to 120 days of age, and slowed down from 300 to 500 days of age. The growth rate of knob in female goose was slower than that in male goose. There were essential differences in the composition of Yangzhou goose knob and Magang goose knob. The subcutaneous tissue of Magang goose was rich, and the thickness of epidermis, dermis and various layers was significantly smaller than that of Yangzhou goose (p < 0.05). With the growth of goose knob, the cells of the epidermal spinous layer became denser and gradually condensed into an overall structure, and there was a clear boundary between the dermis and epidermis after adult. In adulthood, the fiber fascicle network was staggered and dense, with greater toughness and elasticity, and the stratum corneum, epidermis, reticular layer, dermis and other skin structural layers became thicker.

“…The offspring obtained from crossing those breeds surpassed the parental breeds in productivity and viability. In addition, they indicate the influence of interbreeding on the exterior features of poultry, affecting its meat productivity (Honka et al, 2022; Ivanov et al, 2021; Lee, 2021). A group of scientists working with Lalev et al (2014), obtained similar results.…”

Productive qualities of geese when crossing breeds and using hepatoprotective complex

et al. 2023

The study was on a one‐way cross between Wanxi male and Lindov female geese, and tested the effects of a hepatoprotective compound on growth and other traits in the parental and one‐way cross involving male and female progeny. The hybrids obtained from crossing had high viability and productivity; their level was also positively affected by giving a hepatoprotective complex. Female parents were the Lindov breed's geese, and male parents were 120 geese of the Chinese Wanxi breed. During the growing period, hybrid young birds were receiving a hepatoprotective complex in the amount of 1.0 mL per 1 L of water for 7 days. The research took into account geese' safety indices, live weight, and absolute and average daily gain. The interbreeding results prove that the resulting hybrids' safety index is 2.38%–4.54% higher than the parent forms' safety index. The hybrids' live weight increased by 8.4% due to a higher increase in live weight by 16.5%–22.1% allowing us to conclude the positive effect of crossing and using a hepatoprotective complex when breeding geese. The research made it possible to improve geese' productive qualities through hybridization and the use of a hepatoprotective complex. This information can contribute to the genetic improvement of body size in current breeding programs.

“…Biotechnology considerably influences the poultry industry to identify pathogens variants, diagnose infected birds, produce live recombinant vaccines and produce antibiotics (Burt, 2002; Havenstein et al , 1992). Other areas such as genetic development, feed nutrition and probiotic use for disease management can be helpful through biotechnology (Lee, 2021; Kabir and Islam, 2021). Proper poultry nutrition is one of the areas for implementing biotechnology concepts and increasing meat and egg production efficiency.…”

Purpose Second-order system-dynamics engineering (SOSDE) involves constructing and running enterprise manufacturing simulation models with new proposals for operational processes, byproducts, supply chain and/or downstream marketing designs. This paper aims to describe sustainability the principal lessons from enacting SOSDE research for achieving goals in large manufacturing firms. Design/methodology/approach This study is a case research commentary in the agricultural industry that contributes abductively derives six principal lessons from SOSDE research on introducing sustainability-focused manufacturing and product innovations. Operational processes in large-scale poultry processing plants in an emerging market represent the specific industry and firm domain of this case study. Alternative SOSDE simulation models of decisions, materials flow and outcomes with versus without operational innovations were constructed following one-to-one interviews with experienced farm managers and entrepreneurs. Findings The principles demonstrate how large farms in a developing nation (i.e. Bangladesh) go about adopting radically innovative manufacturing, supply chain and marketing operations to improve traditional operations. This study confirms and expands on the general observation that SOSDE can help achieve sustainability and environmental, social and governance goals, contribute new value outcomes by converting unused production wastes into valuable byproducts and introduce design efficiencies in production, supply chain and marketing processes. SOSDE complements, while being a revolutionary departure from, “six sigma management programs” that focus on achieving exceptional and near mistake-free manufacturing operations. Both represent distinct philosophies and sets of actions that sometimes can conflict with one another. Embracing both successfully in the same enterprise is a goal that may appear unreachable, seemingly impossible to achieve and yet represents a manufacturing/marketing epitome that is observable in exceptional enterprises. Research limitations/implications This paper may generate controversy as well as advance interest in applying SOSDE in introductions of improved manufacturing, supply chain and marketing operations aiming to accomplish radical improvements in sustainability goals. Practical implications This commentary describes how using SOSDE and running alternative production simulations with versus without including superior, radically new, process innovations enable the firm to find and eliminate glitches in system changes and reduce the fear associating with breakdowns and financial losses due to inadequate knowledge of operating new industrial procedures and outcomes. Social implications Introductions of superior radically new innovations in industrial manufacturing and marketing via SOSDE frequently include manufacturing firms embracing new environment sustainability objectives and additional marketable byproducts from the firm's main productions lines. This commentary offers details on how this process is enacted in poultry manufacturing in an economically emerging nation. Originality/value Running simulations in SOSDE research offers a low-cost, fast and in-depth method to test “what-if” impacts of enhanced and radical innovations into product/service manufacturing operations – benefits supporting the recommendation to apply systems dynamics in business and industrial marketing.
