Abstract:
Sustainable dairy farming is emerging as a major alternative to wheat-rice cropping system in Punjab state which is already producing almost 10% of the milk produced with <3% of the dairy animal population in India. Evidently the milk productivity per animal is more than three times of national average in Punjab with some of the herds of progressive dairy farmers reaching milk yield of 8,000 kg/lactation, which is comparable to average lactation yield in dairy developed countries. In fact, faster development of dairy sector is essential to de-accelerate the deterioration of natural resources of sub soil water and soil health of Punjab. Thus, significant opportunities through technological innovations were created for enhancing income of smallholder and rural-based dairy systems in coming decades and hence poverty reduction. The addressed dairy farming technologies include improvement in dairy animal germplasm, cost-effective feeding strategies, shelter management, detecting safety of food of animal origin, zoonotic diseases diagnosis, development of quality meat products and value added milk products as well as tackling toxicities and deficiencies, disease diagnosis, and veterinary care. In brief, keeping in view the expected high demands for dairy products, technological innovations as well as ability to transfer technology from lab to field in dairy farming system is must for facing the challenge of increasing production without increasing the animal population, and bringing down the cost of production for greater economic returns to the farmers of Punjab state.

Title: Bovine leukemia virus in Chinese dairy and beef cattle
Time : 11:30 - 12:00
Biography:
Y Yang is a PhD student from College of Veterinary Medicine, Yangzhou University, and now he is a visiting scholar in College of Veterinary Medicine, Kansas State University. He has published 5 papers studying on cattle in reputed journals, such as Journal of Dairy Science.
Abstract:
In this study, we investigated the prevalence of bovine leukemia virus (BLV) infection in dairy and beef cattle at individual-level in 19 provinces of China, and the influence of BLV infections on complete blood counts, biochemical parameters and milk composition in cows. A fluorescence resonance energy transfer (FRET) quantitative PCR was established in this study to detect BLV proviral DNA and compared with a commercial CELISA against gp51. Our data showed that 49.1% of dairy cattle (964/1,963) from 6 provinces and 1.6% of beef cattle (22/1,390) from 15 provinces were BLV positive. In a detailed study of 105 cows (26 BLV-uninfected cows and 79 BLV-infected cows) in a dairy farm in Jiangsu province, 18 complete blood count parameters, 13 biochemical parameters and 5 parameters of milk composition were tested. Comparing BLV-infected and BLV-uninfected cows, all the biochemical parameters we studied in 105 cows did not differ significantly, while 9 of the 18 complete blood count parameters were significantly different. The BLV-infected cows had significantly higher levels in 6 parameters (white blood cell count, lymphocyte number, lymphocyte percentage, hemoglobin, hematocrit, and red blood cell distribution width) and significantly lower levels in 3 parameters (monocyte percent, granulocyte percent, and platelet count). The lactose level in milk in BLV-infected cows was significantly lower than that in BLV-uninfected cows. Taken together, our results indicate that BLV infections are widespread in the dairy farms of China, and BLV-infection may affect blood count and lactose metabolism of cows

Title: Effects of sulfur on the nutrition value of DDGS for beef cattle
Time : 12:00 - 12:30
Biography:
Liwen He is a PhD candidate of China Agricultural University, majoring in Animal Nutrition and Feed Science and specifying in Ruminant Nutrition. He has published 4 SCI papers and research subject is about efficient use of crop straw in livestock.
Abstract:
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 24 h, 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.

Title: Dairy products
Time : 12:30 - 13:00
Biography:

Abstract:
Dairy products are products derived from milk for various purposes. Dairy products ranges from edibles such as creams, milk powders, alcohol, skimmed milk, casein, whey, butter, cheese, lactose, chocolate milk, milk drinks and various traditionally produced dairy products. Non edible derivative include fabrics and plastic products. Several newer dairy products are yet to be harnessed from milk. This would create frontier for production of newer dairy products. Livestock keeping for dairy and other purposes has been since ancient times. The pastoral livestock keeping for multipurpose reasons including milk production was solely for domestic use. This period was marked with production of mostly organic dairy products with great health benefits but with extremely low shelf life. The emergence of civilization and development brought organized dairy keeping with specialized dairy breeds solely for milk production. This ushered in commercial dairy production which enhanced income generation of farmers and contributes to growth of economy of most countries. Most commercial dairy products are bedeviled with harmful substances as preservatives. The use of preservatives such as sodium tripolyphosphate in dairy products although are safe for consumption poses long time harmful effects to humans. Dairy industry should as a matter of necessity abolish the use of such substances and source for safer methods of extending the shelf life of dairy products. Future prospects in the industry would include provision of Government regulations to oversea the activities of dairy industries and dairy products available in the market.

Abstract:
Oxidative stress is the result of excess free radical production beyond the capacity of antioxidant defense of the body. Dairy cows during periparturient period experience oxidative stress, which may increase risk of developing various periparturient disorders. Over the past few decades, use of herbal drugs for treatment of various diseases in dairy cattle has gained momentum as they have high safety profile, good efficacy and do not pose drug residue problem. The present study was therefore, planned to evaluate the efficacy of herbal preparation supplementation on oxidative stress parameters during periparturient period. A total of sixteen healthy multiporous crossbred dry cows during their last trimester of pregnancy were randomly divided into two equal groups. Group I was kept as control, while Group II received herbal preparation “Stress Check” (Indian Herbs) @ 15 gram per day/ cow during last fifteen days of expected calving and up to the first fifteen days after calving. Blood samples were collected by jugular venepuncture during far off dry (FOD) period (>10 days following dry off and not < 30 days prior to calving), close up dry (CUD) period (Between 3 and 21 days prior to calving) and early milking period (3 to 30 days in milk) , for the estimation of lipid peroxidation (LPO), super oxide dismutase (SOD), reduced glutathione (GSH), total proteins, albumin, blood urea nitrogen (BUN), creatinine, glucose, Non esterified fatty acids (NEFA), Beta hydroxyl butyric acid (BHBA), calcium, magnesium, phosphorus, sodium, potassium, copper, iron and zinc. In comparison to Group I, significant (p<0.05) decrease in erythrocytic LPO along with non significant increase in the SOD and GSH levels were noticed in the Group II during early milking period. Within group, a significant decrease in the LPO levels in the early milking period as compared to the FOD period was evident. Glucose levels in Group II was significantly higher than Group I during the early milking period. The mean BUN and sodium levels were lower than the normal range in Group II, during the early milking period, while mean levels of creatinine, total protein, albumin, NEFA, BHBA, calcium, magnesium, phosphorus, sodium, potassium, copper, iron and zinc remained within the normal range, though values varied considerably. The present study revealed that the herbal preparation, “Stress Check” was effective in reducing oxidative stress in dairy cows during the periparturient period.

Abstract:
The GIT of ruminant animals harbors diverse microbes; some are pathogenic and antibiotic resistant residing as normal flora and are shed in feces. Apparently, accidental or deliberate release of feces into the environmental can cause deleterious effects. However, animal manure is viewed as a potential source of contamination and infection if not properly managed or treated. Consequently, the microbial load of manure obtained from the Fort Hare Dairy Trust was determined by the viable plate count method and selected zoonotic bacterial pathogens were isolated, identified and characterized based on cultural, morphological and biochemical properties. Confirmed isolates were subjected to antibiotic sensitivity assay by Kirby-Bauer disc diffusion method while employing a panel of thirteen commercial antibiotics. Isolates were described as sensitive or resistant based on the breakpoints of the diameter of zones of inhibition in accordance with the Clinical Laboratory Standards Institute. The levels of Escherichia coli, Salmonella/Shigella species and Campylobacter species were 3.0x105, 5.0x104 and 8.1x103, respectively. A total of 92 bacterial pathogens were isolated and comprised of 30 E. coli, 33 Salmonella sp, 16 Campylobacter sp, 4 Shigella sp and 9 Proteus sp. All the isolates belonging to the family Enterobacteriaceae were highly sensitive to Ciprofloxacin while 87.5% of the Campylobacter strains were sensitive to Chloramphenicol and Tetracycline. However, the antimicrobial resistance demonstrated ranged from 0-100%. In conclusion, the presence of resistant isolates of these zoonotic pathogens indicates that our sample is a potential reservoir of antibiotic resistance determinants in the environment which is an issue of public health importance.

Yasir Ali has completed his M.Phil in Animal products technology at the age of 27 years from Sindh Agriculture University Tandojam.
Abstract:
Present study was carried out with the aim to utilize chhana whey in beverages as soft drink and enhance the value addition in dairy products. Chhana whey beverages were prepared at the department of Animal Products Technology, Faculty of Animal Husbandry and Veterinary Sciences, Sindh Agriculture University Tandojam. Buffalo milk was coagulated by direct acidification using citric acid (0.5%) at 70 °C, and coagulum was drained into chhana whey. Under preliminary studies, the chhana whey beverages prepared by addition of two sweetening agents [i.e date extract (8%) and cane sugar (6%)] with and without apple flavour (0.15%) were more acceptable than that of prepared by addition of single sweetening agent [i.e cane sugar (6%)] with orange or apple flavour. In further study a total of three trails were conducted, and in each trial whey beverages were prepared from chhana whey with addition of two sweetening agents [date extract (8%) and cane sugar (6%)] with and without apple flavour and evaluated for physico-chemical and sensory characteristics. The mean acidity (%) of unflavoured chhana whey (group A) beverage (0.50±0.03%) and flavoured chhana whey (group B) beverage (0.51±0.03%) was not significantly different (P>0.05) from one another. Mean pH value of group B beverage (4.16±0.01) was not significantly different (P>0.05) from that of group A beverage (4.16±0.02). The mean specific gravity was found to be similar in group B beverage (1.037±0.001) compared to that of group A beverage (1.036±0.001). The average moisture content was found relatively similar (P>0.05) in group A beverage (87.32±0.14%) to that of group B beverage (87.05±0.16%). The average fat content of group B beverage (0.34±0.03%) was not statistical different from that of in group A beverage (0.37±0.05%). Average protein content was found to be slightly lower in group B beverage (1.55±0.05%) in contrast to that of in group A beverage (1.59±0.08%). The mean total carbohydrate content of group B beverage (9.98±0.2%) and group A beverage (9.57±0.23%) was not significantly different (P>0.05) from one another. Ash content was found slightly lower in group B beverage (1.12±0.02%) compared to that of group A beverage (1.16±0.03%). Chhana whey beverage with apple flavour was better (P<0.05) in odour/aroma (7.90±0.51) and taste/flavour (38.86±1.29) than that of unflavoured beverage.

Abstract:
Twelve cross bred cows which crossed transition period from close up dry (CUD) to fresh stage uneventfully based on the results of metabolic profile screening and ultrasound were selected for trial of herbal Vitamin E Selenium powder supplied by Indian Herbs. Animals were randomly divided into two groups (control and test) each containing six animals. Controls were not supplemented whereas animals in test group were supplemented with herbal Vitamin E- Sel powder @ 6gm orally for 20 days. Follow up of both groups was done after completion of trial period (≥25 days in milk). Significant decline in lipid peroxidation (LPO) levels after supplementation in test group along with non significant increase in levels of super oxidase dismutase (SOD) and reduced glutathione (GSH) as compared to fresh stage was observed. On the other hand LPO levels recorded non significant increase as compared to fresh stage in control group along with non significant decline in levels of SOD and GSH. Significant decrease was observed in total leukocyte count (TLC) in test group. There was a non significant improvement in overall biochemical parameters as compared to fresh stage in supplemented test group. Control group recorded significant decline in levels of total plasma proteins (TPP) at >25 DIM. There was a significant rise in milk fat percentage in supplemented test group as compared to unsupplemented control group.
