An Exploration Of The Effects Of An Early Postpartum Intravenous Infusion With Carnosic Acid On Physiological Responses Of Transition Dairy Cows, Tainara Michelotti Jan 2021

An Exploration Of The Effects Of An Early Postpartum Intravenous Infusion With Carnosic Acid On Physiological Responses Of Transition Dairy Cows, Tainara Michelotti

Electronic Theses and Dissertations

The transition period is commonly defined as the last 3 wk before parturition to 3 wk after parturition. It is the most critical stage of the lactation cycle of high-producing dairy cows. The period consists of a complex interplay of metabolic and hormonal adaptations, inflammation, and immune activation. During the transition period, dairy cows commonly face oxidative stress, an underlying factor for dysfunctional immune response and enhanced inflammation, which can further increase the susceptibility of dairy cattle to health disorders and decrease productivity. In the last few decades, there has been an increased interest in studying alternative natural compounds with …


Search For New Fertility Markers In Bull Sperm, Saulo Menegatti Zoca Jan 2021

Search For New Fertility Markers In Bull Sperm, Saulo Menegatti Zoca

Electronic Theses and Dissertations

Sperm are stored for extended periods of time in the epididymis, but upon ejaculation motility is increased and lifespan is decreased. After insemination, sperm must traverse the female barriers and undergo capacitation to complete fertilization; however, there are differences in fertility even among bulls that successfully pass a breeding soundness exam. For any potential marker of fertility, there must be variability expressed among animals. The series of studies in this dissertation had the objective 1) to evaluate differences between epididymal and ejaculated sperm and respective fluids proteins to understand increased longevity of epididymal sperm; 2) to evaluate the potential of …

Southern Ocean ecosystems are globally important. Processes in the Antarctic atmosphere, cryosphere, and the Southern Ocean directly influence global atmospheric and oceanic systems. Southern Ocean biogeochemistry has also been shown to have global importance. In contrast, ocean ecological processes are often seen as largely separate from the rest of the global system. In this paper, we consider the degree of ecological connectivity at different trophic levels, linking Southern Ocean ecosystems with the global ocean, and their importance not only for the regional ecosystem but also the wider Earth system. We also consider the human system connections, including the role of …

Training Improves The Reliability Of Temperament Assessment In Cattle, Jamie T. Parham, Jessica J. Schmidt, Ronald M. Lewis

Nebraska Beef Cattle Reports

Accurate and precise measurement of docility in cattle is paramount when including temperament as a criterion for selection. The value of training individuals in assigning a docility score was evaluated by comparing the reliability of individual assessments of temperament in beef cattle before and after various instructional methods. Preceding training, participants’ assessment of cattle behavior, videoed while each heifer was restrained in a chute, was not impacted by age, gender, or pre- existing cattle handling experience. Groups of participants that received additional training were more accurate and precise in evaluating temperament, regardless of training method, compared to those without. No …

Power Of Body Live Weights In Differentiation Physiological Growth Of Goat Breeds, Raed Alatiyat, Amani Al-Dawood Jan 2021

Power Of Body Live Weights In Differentiation Physiological Growth Of Goat Breeds, Raed Alatiyat, Amani Al-Dawood

Turkish Journal of Veterinary & Animal Sciences

We assumed that live body weight (LBW) would be useful to be utilized as informative categorical variable in differentiation goat performance towards better assignment into breeds. One-day old goat kids of both sexes were separately allocated as 3 breeds: Baladi, crossbreds and Shami. The kid LBW was recorded weekly until the 12th week of age. Weekly LBW showed a significant increase (p < 0.05) for both males and females of the 3 breeds and highly significant (p < 0.0001) between breeds. The high phenotypic correlation between most of the studied measurements encouraged us to investigate their efficiency in breed differentiation at early life age. Results showed that only LBW of the week 1, 2, 5, 9, and 11, and week 1, 2, 3, 11, and 12 were efficient in discriminating male and female kids, respectively. These results were better presented by showing significant genetic distances (p < 0.0001) between the breeds using the Unweighted Pair Group Method with Arithmetic mean (UPGMA) dendrogram. It is inferred that the phylogenetic tree lengths of the three breeds were 29.02 and 222.13 for male and female kids, respectively. Baladi and crossbred kids of both sexes grouped into one cluster closer than Shami kids. The canonical discriminant analysis was proved its successfulness for identifying breed based on LBW measurement.

In this study, maize and legume intercropping were evaluated in terms of silage yield and quality. Maize (Zea mays L.''M'') was intercropped with soybean (Glycine max L. ''S'') and cowpea (Vigna unguiculata L. ''C'') as binary mixtues (maize + legume), and the seed rates were as follows: 100 + 0%, 75 + 25%, 50 + 50% and 25 + 75%. The harvested plants were chopped with the particle size of < 2, ensiled in 2 kg plastic jars and left fermentation at 25 ± 2 °C for 45 days. In this study, silage yield, dry matter ratio, pH value, crude protein ratio, acid detergent fiber, neutral detergent fiber, digestibility of dry matter, dry matter intake, total digestibil nutrient relative feed values, lactic acid, acetic acid, butyric acid, malic acid, citric acid, succinic acid, oxalic acid, potassium, phosphorus, calcium, and magnesium contents were determined. All the M + S mixtures showed high performance in terms of Flieg score and lactic acid content. The highest relative feed quality value was determined in the sole cowpea (156.4) and 25M + 75S% (148.5) mixture. As a result, intercropping maize with legumes resulted in superior silage quality without a reduction in yield.

In Vitro Gas Production And Fatty Acids Biohydrogenation Of Diets Containing Different Unsaturated Fatty Acids Sources Plus Crude Glycerin, Arturo Samuel Gomez Insuasti, Yury Tatiana Granja-Salcedo, Julian Andres Castillo Vargas, Juliana Duarte Messana, Ana Paula De Oliveira Sader, Telma Teresinha Berchielli

Turkish Journal of Veterinary & Animal Sciences

An in vitro trial was conducted to evaluate the effects of different unsaturated fatty acids (UFA) sources plus crude glycerin (CGL) on gas production and rumen biohydrogenation (RBH). Incubated diet corresponded to diets containing corn silage (30%) and concentrate (70%) composed of corn, urea, mineral salts, CGL, and different UFA sources as follows: no additional fat (NAF), rumen protected fat (RPF), soybean oil, linoleic acid (LA) or alpha-linolenic acid (LN). Methane concentrations in LA and LN were lower compared to NAF (p < 0.001), but when CH4 was expressed as a proportion of total gas, NAF and RPF showed the greatest values among evaluated UFA sources (p = 0.001). 18:1 t11 concentration showed a faster increase from 0 to 1 h and a slower decrease from 1 to 36 h of incubation, irrespective of UFA source. A higher C18:1 t11 production rate was observed from 1 h to 5 h of incubation, where LA and LN have higher values compared to NAF and RPF diets (p < 0.001). Diets with a high content of LA may be efficient as a nutritional approach to reduce methane production and RBH, resulting in positive effects on vaccenic acid concentrations.
