This poster describes the modern method of Weissenberg effect observation in condensed milk or whipped cream using a simplest tunable laser-based optical setup (TDLSR – «Tunable Diode Laser Spectroscopic Rheogoniometry»). The DIY method to be described here involves minimal nomenclature of low-cost or second-hand devices and accessories. We now describe only a general technique for rheometric measurements with this setup, because any variation on the specified example can be provided by the basic principle of the setup construction.

This paper is a comprehensive review of current state in lab-on-a-chip techniques for dairy product analysis including some unpublished results of our research group, which differ both in the calibration and registration principles from their foreign counterparts. The fundamental difference of those devices is the possibility of calibration using spectrophotometric or colorimetric temperature and the tuple analyte systematization in intelligent databases. The functional characteristics of our devices at the time of development were not inferior or even superior to all the known analogs. Labs-on-a-chip with a comparative analysis scheme where the main analyte parameters in a reference lab-on-a-chip were compared with those in a test lab-on-a-chip were designed in order to replace the functions of complex two-beam spectral instruments. Later a number of the above device modifications have been developed implementing or replacing the functions of colorimetry, nephelometry / turbidimetry, coagulometry and pioscopic detection of coacervating lipid inclusions. The use of specialized adapted spectroscopic software and the advanced spectral-mathematical models in the output data interpretation allows to increase the heuristic value of the control process, which can be of great interest for veterinary inspection and the feeding quality control based on chemometric milk parameters in dairy zootechnology.

Toxic levels of hydrogen sulfide (H2S) gas released from dairy manure storages have imposed risks to animal and human health. Gypsum (calcium sulfate) is a valued bedding material for cattle but has contributed to the excessive H2S emissions. This study aims to assess the effect of iron oxide as a promising additive to dairy manure storages on mitigating H2S releases. Four treatments with decreasing dosages of iron oxide will be applied to gypsum-laden dairy manure. The effectiveness of iron oxide in reducing H2S emissions will be quantified using a highly accurate gas analyzer so that an economically effective dosage of iron oxide will be identified from this study. This research will also deliver an improved understanding of mechanisms of manure gas emissions. Critical evidence from this study will guide industry, government agency and farm manager actions in reducing toxic gaseous pollutants to improve human health and animal welfare surrounding manure storages.

This project is part of a larger task pursuing the development of naturally produced, health-contributing, polyphenol-enriched milk products that are derived from byproduct plant matter from agricultural sources. Apple pomace (AP), an abundant agricultural by product in Canada has a high polyophenol content (1000-1415g gallic acid equivalent/100g dry weight). 17,36 The objective of this study is to evaluate the effects of in vitro rumen digestion on the total polyphenol content and free radical scavenging activity of AP. AP will be collected fresh and kept at -20°C until analysis. Rumen inoculum will be collected from a mature lactating cow and in vitro digestion will be performed for 24 and 48hr of digestion in an ANKOM RF Gas Production System as per manufacturer’s instructions.3 After digestion, the samples will be centrifuged at 26 940g and filtered through 0.2um polyethersulfone filters to remove bacterial cells.10 All samples (treated and untreated) will be freeze dried and ground, after which polyphenols will be extracted by solvent extraction (80% methanol at 21°C for 1hr).33 Fast Blue BB assay for total polyphenol quantification and 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity assay will be performed on all samples in triplicate with 3 technical replicates to assess the extent of polyphenol degradation in the rumen33. The fraction of polyphenols remaining after in vitro digestion will be roughly representative of the amount available for absorption into the cow’s bloodstream and subsequently the mammary gland.

Camel milk, despite its richness and significant production remains a relatively little consumed and little processed product, because insufficiently studied and developed. This milk is distinguished by a high content of Vitamin C and antibacterial molecules (lysozyme, peptidoglycan recognition proteins, lactoferrin…). These peculiarities come in most cases, from the nature of forage plants consumed by the dromedary (rangeland). In order to improve camel milk production, some breeders have been practicing for some time a semi-intensive farming (semi-stall / introduction of an "artificial" food). A preliminary investigation conducted, with a dozen farmers who practice two farming systems (extensive and semi-intensive) in the region of El-Oued, in Algeria allowed to locate production to about 3.5 l / d and 2 l / d for the two systems, respectively. The physico-chemical analysis of milk samples from two breeding camels systems was performed by measuring the pH, acidity, density, total solids, solids not fat, ash rates, lactose, calcium , proteins, vitamin C ... These analyzes showed that the transition from extensive farming system to the semi-intensive have an impact on physico-chemical and organoleptic quality.

To investigate the effects of sulfur on the nutrition value of DDGS for beef cattle, in vitro cultivation was conducted for 72 h with the rumen fluid collected from steers, setting different sulfur levels (0.346%, 0.692% and 1.038%) and various sulfur sources (Na2SO4, Na2SO3, Na2S2O3 and Na2S), monitoring the fermentation parameters (dry matter digestibility, gas production and its rate) and model predicted indicators (organic matter digestibility, metabolizable energy, net energy, microbial protein, partitioning factor and gas yield). The results showed that, high sulfur level (0.692% and 1.038%) only decreased (P<0.05) asymptotic gas production (b), while different sulfur sources resulted in various parameters, more specifically, sulfur from Na2SO4 and Na2S produced more gas (P<0.05) with faster rate (P<0.01) of gas production than those of Na2SO3 and Na2S2O3, while Na2SO3 had the highest b and inverse for Na2SO4 (P<0.01), which tended (P=0.09) to produced lower total volatile fatty acids than the others; sulfur from Na2SO4 and Na2S also had a lower (P<0.01) DMD in 24h, MCP, PF24 and a higher (P<0.01) OMD, ME, NEm, NEg, GY24 than those of Na2SO3 and Na2S2O3. These results suggest that DDGS with different sulfur content ranging from 0.346% to 1.038% have a similar feed value and dietary sulfur source exerts a great effect on its nutrition value for beef cattle.

The cattle × yak hybrids (Dimjo Chauries) have similar high altitude tolerance and have the advantages of heterosis in comparison to purebred yaks. Effects of grazing by season, the parity on milk yield as it relates to the composition of Dimjo Chauries, are unknown in the Kanchenjunga Conservation Area (KCA) of Nepal.To do so, a common transhumant route was identified at 4100 m a.s.l which was grazed both during upward (summer-July) and downward (September-early winter) herd movement. Milking Dimjo Chauries of 2nd, 4th and 6th parities each having six lactating animals selected at similarity in daily milk yield, days of parturition within each group. Daily milk yield and milk composition were analyzed for 7 days by following a 7 days long adapatation period at both measuring periods. Daily milk yield, energy corrected milk yield and fat content were significantly affected (P<0.05) by season and parity and their interactions. Highest daily milk yield was obtained from 6th parity hybrids (5 kg/day) in July and the least was observed for 2nd parity groups in September (1.5 kg/day). Milk fat content was highest at September for 4th parity hybrids (about 8%). Milk protein and lactose content higher at July (3.32% protein vs. 4.67% lactose) than at September (3.22% protein and 4.54% lactose respectively as expected due to advancing lactation and vegetation. Research results revealed that Dimjo Chauries above 4th parity could be promising for commercial herding as has been shown from their higher daily milk yield and daily outputs of milk constituents

Three crop straws (rice, corn and wheat) were chosen to study the effects of steam explosion on in vitro gas production and rumen fermentation and in Sacco NDF disappearance and bacteria attachment. The results showed that the steam explosion significantly increased the 96 h gas production (GP) (P<0.05) and the rate of GP of the three straws (P<0.05). The steam explosion also significantly increased the concentration of total volatile fatty acid (VFA) and the molar proportion of propionate (P<0.05), while significantly decreased the concentration of non-ammonia nitrogen (NH3-N) and the molar proportion of acetate and the ratio of acetate to propionate (A:P) (P<0.05). The activity of enzyme β-glucanase, avicelase and carboxymethyl cellulose (CMCase) were increased significantly following the pretreatment of steam explosion (P<0.05), which presented no significant effect on the activity of xylanase (P>0.05). The steam explosion significantly increased the neutral degradable fiber (NDF) disappearance when the straws incubated in sacco for 24, 48 and 96h (P<0.05). The value a(immediately disappear fraction)and b(potentially degrade fraction) of the model were both increased significantly when the straws pretreated by steam explosion (P<0.05). For bacteria attachments, the steam explosion significantly increased the attachment of F. succinogenes (P<0.05), but showed no effects on the attachments of R. flavefaciens and R. albus(P>0.05).Resultsin the present study indicated that the steam explosion could be widely used to enhance the nutritive value of crop straws for itsfunction of improving their digestibility, rumen fermentation and bacteria attachment (F. succinogenes).

The objective of this study was to investigate the effect of steam explosion on chemical compositions and efficient energy values of corp residues. We regarded steam-exploded crop residues (rice straw, wheat straw and maize stover) as treatment groups and untreated ones as control groups. Results indicated that the interaction between steam explosion treatment and the variety of crop residues has significant influence on chemical compositions of crop residues. Steam explosion treatment of crop residues decreased NDF significantly (P<0.01), and compare with raw material, NDF content of rice straw, wheat straw and maize stover lowered 21.46%, 32.11%, 28.34% respectively. ADL of crop residues increased significantly after steam explosion (P<0.05). The content of CP, EE and Ash increased significantly after steam explosion (P<0.05). Moreover, predicted effective energy values of each steam-exploded residue were higher than that of untreated ones. The DE, ME, NEm and NEf of steam-exploded rice straw improved 46.21%, 46.25%, 49.56% and 110.92% compared with untreated ones. Correspondingly, the energy values of steam-exploded wheat straw were 261.78%, 261.29%, 274.59% and 1014.69% greater than that of wheat straw. The energy values of steam-exploded maize stover were 109.58%, 107.71%, 122.57% and 332.64% greater than raw material. In conclusion: steam explosion treatment could significantly alter the cell wall and the other components of crop residues. There existed strong interaction between steam explosion treatment and the variety of crop straw. The efficiency of steam-explosion wheat straw was higher than the other two kinds of residues.

The dairy industry in Nigeria has passed through a tortuous and convoluted process of development and sustainability over the past 30-40 years. A mirage of limiting factors had led to this slow pace of development. Small and medium scale dairy producers are very few (50-120 dairy farmers) with an average dairy herd size of around 20 (1-600 dairy cattle). The main dairy breeds in the country are the exotic Friesian-Holstein breed (80-90%) and the Jersey (10-15%). Other breeds are crosses between the Friesian-Holstein and the local cattle breeds (mainly Bunaji and Gudali). There are very few crosses between the Jersey and the local cattle breeds. The average milk yield per cow per day is around 8 litres/cow/day (range is between 5-28 litres/cow/day). Some of these limiting factors against optimal dairy production in Nigeria are: - (i) Lack of institutional/ national policy and facilitation on profitable dairy production (ii) Suboptimal quantity and quality of feed availability all year round (iii) Harsh environmental conditions such as high ambient temperatures, high humidity, prevalence of endemic dairy diseases (iv) lack of development and enforcement of bio-security measures at farm level (v) Absence of a dairy institute in Nigeria where dairy technicians can be trained (vi) lack of an up-to-date knowledge and skills on dairy technology by veterinarians and animal scientists (vii) lack of a scientific evolution of indigenous dairy breed that is adaptable to the ecology of Nigeria. For the dairy industry in Nigeria to be profitable and sustainable, these limiting factors must be addressed squarely and urgently so that we can meet the animal protein requirement for the over 180 million inhabitants of Nigeria. This paper suggests how each of these limiting factors can be addressed in order to achieve profitability and sustainability in the dairy industry in Nigeria. Some examples of dairy farms set-ups in Nigeria will be show-case to indicate that Nigeria is already on the right path of dairy development and that she may just require a little push by her government political/economic policies and financial policies; and also by fellow foreign mega dairy farmers that will partner with small and medium scale dairy farmers in Nigeria. Some critical areas of partnership are:- (i) the provision of modern dairy technologies (modern farm tractors and implements and dairy products processing technologies), (ii) the provision of human resources in terms of dairy specialists (milk production and milk processing human resources) and the injection of financial support for local manpower training of middle cadre and executive dairy staff to ensure sustainability of the industry. This type of a multi-faceted intervention will transform our medium and small scale dairy industry into large scale commercial dairy farms with its added value downstream dairy products processing factories. This will then ensure sustainability of the dairy industry in Nigeria.
