Abstract:

Records on four bulls and 96 of their progeny born from 2005 to 2011 with pedigree information were used to estimate the impact of bull performance on progeny early growth and the genetic relationships between traits of bull and their progeny. Traits included in this study were metabolic body weight, feed intake and residual feed intake (RFI) for bull performance and birth weight and average daily gain for progeny performance. The variance and covariance components were estimated by the REML method with the VCE computer program. The metabolic body weight of breeding bulls ranged from 92.88±1.2

Abstract:

Yearling bull fertility, measured as pregnancy rate, percentage of calves born during the first 4 and 6 wk of calving and mean and median of calving date distribution, were studied in 109 single-sire breeding herds of two breed groups over a 10-yr period. The breed groups were Herefords bulls mated to purebred and crossbred Hereford cows, and Beef Synthetic bulls mated to Beef Synthetic cows. The bulls averaged 14 mo old at the start of breeding. The average bull-to-cow ratio was approximately 1:22, and the breeding season started on 1 July each year and extended for 60 d. Two out of 109 bulls

Abstract:

Abstract The Cal Poly Bull Test has been offering valuable information for genetic improvement via a performance test of yearling beef bulls across the western United States since 1951. Growth and reproductive performance phenotypes were measured and collected over time. Therefore, the objective of this study was to determine the relationship between growth traits and semen quality traits. Performance records and semen samples of Hereford and Angus bulls were collected over a 12-year span from 2001–2013. A total of 1,982 records from Angus (n = 1692) and Hereford (n = 290) bulls were analyzed.

The size of the SC population established before puberty is one of the major factors determining DSP in the bull. Fine needle aspiration (FNA) is a technique used for diagnostic purposes in many species but its application to determine the size of the SC population remains unexplored.

Abstract:

AbstractCereal grains are the most commonly grown crops in the world. Wheat and rice are important commodities which contribute to 50% of the world’s food-calorie intake (McKevith Nutr Bull 29(2): 111–142, 2004). These two cereals are critical to food security in the developing regions. In this context, crop-mapping services can be used for detailed monitoring of the cultivated areas; it can also provide the area statistics of specific crops and the data on their intensity across the landscape. This mapping process is also valuable for government agencies since it provides them with critical information that can be used to manage their stocks (for imports and exports). This chapter dwells on a crop-mapping service developed under the SERVIR-HKH program. In this regard, the needs assessment was carried out with the assistance of the governments of Bangladesh and Afghanistan through a consultation workshop. Wheat mapping in Afghanistan and rice mapping in Bangladesh were the top priorities for the respective governments. Here, we discuss two particular mapping exercises that were undertaken in these two countries: wheat mapping in Afghanistan at a national level and the mapping of Boro rice in selected districts of Bangladesh.

<i>Abstract</i>.—To track individuals in situ, over 12 million salmon and trout have been marked with passive integrated transponder (PIT) tags in the Columbia River Basin, USA. However, few studies have examined long term tag retention as well as tag effects on juvenile salmon and trout. We marked juvenile coho salmon <i>Oncorhynchus kisutch</I> (<I>N</I> = 207), steelhead (anadromous rainbow trout) <i>O. mykiss</I> (<I>N</I> = 221), cutthroat trout <i>O. clarkii</I> (<I>N</I> = 202) and bull trout <i>Salvelinus</I> <i>confluentus</I> (<I>N</I> = 180) with 12, 19, or 23 mm PIT tags and examined tag retention, survival, growth, and physiological performance over a six month period in a laboratory environment. PIT tag retention rates were high for coho salmon (100%), steelhead (95%), cutthroat trout (97%), and bull trout (99%), regardless of tag size. Survival was also high for coho (99%), steelhead (99%), cutthroat trout (97%), and bull trout (88%) and did not vary among tag sizes. Short term individual growth rates for coho salmon marked with 12 mm tags were significantly higher than those marked with 19 mm and 23 mm PIT tags. Likewise, steelhead trout individual growth rates were lower for fish marked with 23 mm PIT tags followed by 19 and 12 mm tags. Conversely, long-term growth rates were positive and not affected by tag size. There were no significant effects of tag size or marking on coho gill Na+, K+, -ATPase activity (μmol ADP x mg protein<sup>–1</sup> h<sup>–1</sup>) and plasma osmolality (μmol kg<sup>–1</sup>) or bull trout hepatosomatic indices. Our study suggests that marking juvenile salmonids with PIT tags results in high retention with little effect upon their survival, growth, and important physiological indicators regardless of tag size in a laboratory environment.

Abstract:

Social media companies have increasingly used global stock exchanges to raise fresh capital needed to expand and commercialise their business models. Despite the soaring proliferation of social media interactions and improving economic fundamentals, many of the high-profile IPOs have underperformed on debut and in secondary trading. This chapter seeks to identify success and failure factors of social media stock market flotations from the operational, industrial and financial perspectives. The research features flagship social media IPOs comprised by the most representative social media Exchange Traded Fund (ETF), the Global X Social Media Index ETF (SOCL), which replicates the price and return performance of the globally recognised Solactive Social Media Total Return Index. The analysis sums up the early evidence of IPO organisation with regard to social media issuers and posits three decisive factors in this process related to: flotation timing, pricing and pre-IPO business integration. The research offers some practical recommendations for future social media IPOs as well as directions for further academic studies at the interface of social media industrial, economic and capital market activity. The following takeaways concerning social media IPOs emerge from the study: 1) Staging and timing: social media companies should mull flotations when a clear-cut path toward cash generation and accrual profits is observable (chronically cash deficient and unprofitable social media tend to underperform on debut and in post-IPO trading) and amid protracted bull markets so as to raise the odds of a propitious IPO climate; 2) Organisation and management: the success of social media going public decisions is a function of seamless IPO organisation (including conservative pricing, share dilution tied to envisaged liquidity and capital expenditure as well as trading and clearing system reliability); 3) Issuer characteristics: social media IPOs are facilitated by businesses commanding a dominant position on the home market, having a diversified core business (including exposure to non-media operations), coming on the stock market either as industry trendsetters or in the wake of successfully executed IPO benchmarks; 4) Factor coalescence: no isolated factor discussed in this chapter can fully explain the performance of a social media IPO – it is rather their combination and interconnectivity that can comprehensively attest to the success or failure of a going public strategy employed by a social media company. From the investment standpoint, the case study analysis demonstrates that a case-by-case (rather than sectoral) approach needs to be adopted for investors seeking to derive gains from social media IPOs, as passive exposure to the entire industry (e.g. via index tracking) is not per se a guarantor of market competitive investment performance.

Abstract:

The results of studying the characteristics of the use of substrates in energy metabolism at different levels of metabolizable protein (8.0 g and 8.3 g per 1 MJ of metabolizable energy) in the diets of 9-month-old Charolais meat bulls with an initial live weight of 260 kg are presented. Based on the data obtained on the energy balance and gas-energy metabolism by the mask method, the ratio of the contribution of the metabolizable energy of the diet to body weight gain and heat production of bulls during the period of intensive growth was determined.

Abstract:

The aim of this study was to explain the birth season effect on Hereford bulls fattening results. The research was made within the project ‘Baltic Grassland Beef’ framework in years 2015 and 2016. Data about 41 Herford purebred bull was used in the research, grown in different farms of Latvia. Bulls were slaughtered in certified slaughterhouse ‘Agaras’ (Lithuania). The average birth weight of the Hereford breed bulls was in border from 42.9 – 45.0 kg. The lowest birth weight was on spring season born bulls – 42.9 kg, but the highest on winter season born bulls - 45.0. Average realization age o

Abstract:

Reconnaissance experiments were conducted to evaluate the productive effect of diets for young cattle. The diets consist of silage prepared from peas and barley in the ratio of 50: 50 and 25: 75, as well as from crushed grain these crops. Mixed crop cultivation is recommended for use in feed production. The average daily gain in live weight of gobies grown on such diets is 927–996 g, slaughter yield is up to 58.8%, and the protein content in the longest muscle of the back is 21.93–23.63%.

Abstract:

Material failure on the microstructural level is important in determining macroscale behavior. When a material is subjected to dynamic (shock) loading conditions, damage and deformation patterns due to spall failure can provide a basis for connecting micro- to macroscale behavior. By analyzing deformation patterns at and around interfaces and boundaries that are representative of those found in engineering materials at high strain rates, we can develop stronger structures that can withstand impact collisions and rapid crack propagation. The addition of surface perturbations to one side of the

Abstract This article describes a preliminary study of an on-going ARPA-E (Advanced Research Projects Agency-Energy) MARINER Phase I project. The hydrodynamic load and dynamic response of an innovative offshore macroalgae cultivation system, Nautical Offshore Macroalgal Autonomous Device (NOMAD), under extreme environmental conditions is examined. The high strength, extremely durable, recyclable carbon fiber (rCF) free-floating long-line is applied with polyculture (Nereocystis luetkeana (bull kelp) and Saccharina latissima (sugar kelp)) in the NOMAD system. This novel macroalgal farming syste
