Effects Of Dietary Inclusion Of Clinoptilolite In Colostrum And Milk On Certain Haematological Parameters Of Calves, Konstantinos Pourliotis, Maria Karatzia, Efterpi Christaki, Panagiotis Katsoulos, Harilaos Karatzias`

Turkish Journal of Veterinary & Animal Sciences

The administration of a natural zeolite, clinoptilolite, in newborn calves via colostrum and milk has been proven to be beneficial in enhancing the intestinal absorption of immunoglobulins and in reducing the incidence and the severity of diarrhoea syndrome. The aim of this study was to investigate whether a 2-month-long supplementation at 2 levels (1 g/kg body weight (BW) and 2 g/kg BW) of clinoptilolite in the colostrum and milk of dairy calves had any effect on their haematological parameters. A total of 84 clinically healthy Holstein calves were assigned to 1 of 3 groups immediately after calving. Group A (n …

Determination Of Optimum Temperature And Photoperiod For Mass Production Of Oxya Hyla Hyla (Serville), Mousumi Das, Arijit Ganguly, Parimalendu Haldar

Turkish Journal of Zoology

Insects are natural food for many vertebrates. Being nutritionally rich, acridids can be used to produce high quality feed for livestock industries. For a sustainable supply for the feed manufacturing companies, a huge acridid biomass must be obtained on a regular basis. Therefore, for successful acridid farming, a laboratory rearing system in semi-controlled conditions is proposed to produce a huge acridid biomass. Experiments were conducted to determine a favorable temperature and photoperiod for rearing the chosen multivoltine species, i.e. Oxya hyla hyla. For this purpose nymphal mortality, growth rate, fecundity, fertility, and adult dry weight were determined. The results revealed …

Turkish Journal of Zoology

A total of 44 molluscan species belonging to 5 classes were identified in 3 transects (including depths of 10, 25, 50, 75, 100 and 200 m) located in Kumkuyu, Limonlu, and Erdemli. Overall, no significant difference in community parameters such as diversity index, evenness index, and species richness was found among transects. The species abundance showed seasonal and depth-wise variations. The highest species richness (6-16 species) was encountered between depths of 10 and 100 m in winter and spring, whereas the molluscan population increased in warm seasons due to the high abundance of Corbula gibba and Nucula nitidosa. Bivalves and …


Growth Performance And Body Composition Of Kutum Fingerlings, Rutilus Frisii Kutum (Kamenskii 1901),In Response To Dietary Protein Levels, Ghaffar Ebrahimi, Hossein Ouraji Jan 2012

Growth Performance And Body Composition Of Kutum Fingerlings, Rutilus Frisii Kutum (Kamenskii 1901),In Response To Dietary Protein Levels, Ghaffar Ebrahimi, Hossein Ouraji

Turkish Journal of Zoology

A feeding trial was conducted to determine the optimal dietary crude protein requirement for Rutilus frisii kutum fingerlings. Five isoenergetic experimental diets were formulated to contain graded levels of protein (32%, 37%, 42%, 47%, and 52%). Triplicate groups of 80 kutum (average weight 0.5 g) were stocked in 250-L tanks and fed to apparent satiation 3 times a day for 8 weeks. The results indicate that the growth performance and feed utilization of kutum were significantly (P < 0.05) affected by dietary protein level. The second polynomial regression of weight gain against protein level yielded an estimated optimal dietary protein requirement of 41.6%. Weight gain, specific growth rate, and feed efficiency increased with increasing the dietary protein level from 32% to 42%, but decreased significantly (P < 0.05) with further increases in dietary protein. The protein efficiency ratio was inversely correlated with dietary protein level. Feed intake was not affected (P > 0.05) by dietary protein level. No significant difference was found in the whole-body protein, lipid, moisture, or ash contents of fish fed the …

Two experimental diets containing either 10% or 20% DDGS with supplemented amino acids (lysine, methionine, isoleucine, and histidine) and phytase were compared to a fish meal-only control diet. Tanks of trout receiving diets containing either concentration of DDGS weighed significantly less at the end of the trial and had significantly poorer feed conversion ratios than tanks of fish being fed the fish mealonly control. There was no significant difference in individual fish length, weight, condition factor, or any fish …


Influence Of Weaning Date And Prepartum Nutrition On Cow-Calf Productivity, Kelsey M. Rolfe, L. Aaron Stalker, Terry J. Klopfenstein Klopfenstein, Richard N. Funston Jan 2012

Influence Of Weaning Date And Prepartum Nutrition On Cow-Calf Productivity, Kelsey M. Rolfe, L. Aaron Stalker, Terry J. Klopfenstein Klopfenstein, Richard N. Funston

Nebraska Beef Cattle Reports

October weaned cows had greater average BCS and BW compared to December weaned cows; however, the level of supplementation on winter range did not impact BCS or BW. Subsequent pregnancy rates (96.5% - 98.5%) were not influenced by weaning date or any winter treatments. Steer progeny showed no differences in feedlot entry BW, final BW, DMI, ADG, or carcass characteristics; and there were no differences in percentage cycling before breeding or in pregnancy rates of heifer progeny.

Beef Heifer Development And Profitability, Matthew C. Stockton, Roger K. Wilson, Richard N. Funston Funston

Nebraska Beef Cattle Reports

The determination of the ideal breeding size of beef replacement females is traditionally centered on maximizing pregnancy rate. Relevant physical and economic relationships were combined into a bioeconomic systems model that identified key profit factors. This system-wide approach encapsulated the physical relationships with relevant costs and revenues, including annual and seasonal variations and measures relative to profitability through the application of an incomplete or modified profit function. Optimaloutcomes were relative to heifer size and management regime.


Statistics Used In The Nebraska Beef Report And Their Purpose Jan 2012

Statistics Used In The Nebraska Beef Report And Their Purpose

Nebraska Beef Cattle Reports

The purpose of beef cattle and beef product research at UNL is to provide reference information that represents the various populations (cows, calves, heifers, feeders, carcasses, retail products, etc.) of beef production. Obviously, researchers cannot apply treatments to every member of a population; therefore, they must sample the population. The use of statistics allows researchers and readers of the Nebraska Beef Report the opportunity to evaluate separation of random (chance) occurrences and real biological effects of a treatment. Following is a brief description of the major statistics used in the beef report. For a more detailed description of the expectations …


Evaluation Of Single Nucleotide Polymorphisms Associated With Fertility And Production Traits In Holstein And Multi-Generational Angus Females, Rebecca Ann Hill Jan 2012

Evaluation Of Single Nucleotide Polymorphisms Associated With Fertility And Production Traits In Holstein And Multi-Generational Angus Females, Rebecca Ann Hill

LSU Master's Theses

The objective of this study was to test the association of single nucleotide polymorphisms (SNPs) with fertility in two populations consisting of Holstein cows and multi-generational Angus cows. The candidate gene approach was utilized and previously described SNPs were tested for possible associations with fertility. Single nucleotide polymorphisms on three genes were evaluated including leptin receptor LEPR, calpastatin CAST, and DGAT1. Fertility traits were evaluated in conjunction with production traits for Holstein females and growth traits for Angus females. One SNP was significantly associated with birth weight (P < 0.05) in Angus females while a trend (P < 0.10) was observed for two markers influencing birth weight performance and three markers influencing weaning weight performance. An association of two SNP for birth weight and back fat thickness in Angus females was identified.!A trend (P < 0.10) was observed for one marker within LEPR influencing average services to conception, two markers within CAST influencing average days open, two markers within CAST and one marker within DGAT1 influencing average protein production, and one marker within CAST and one marker within DGAT1 influencing average milk production. One SNP within LEPR was significantly associated with average milk production (P < 0.05) in Holstein females. An association of one SNP within CAST and one SNP within DGAT1 for average protein production and average milk production in Holstein females was identified. An association of one SNP within CAST for average days open and average protein production in Holstein females was also identified. The association of these markers indicates that the evaluated quantitative trait loci (QTL) region may harbor causative mutations responsible for the variation observed in fertility and production traits. Further evaluation of SNP in these regions is necessary in order to identify mutations accounting for the largest degree of variation for fertility and production traits.


A Novel Immunomodulatory Subunit Vaccine To Combat The Involvement Of Bovine Respiratory Coronavirus Infections In Shipping Fever, Genevieve Elizabeth Lum Jan 2012

A Novel Immunomodulatory Subunit Vaccine To Combat The Involvement Of Bovine Respiratory Coronavirus Infections In Shipping Fever, Genevieve Elizabeth Lum

LSU Doctoral Dissertations

Bovine respiratory coronavirus (BRCoV) is a group 2a coronavirus expressing both hemagglutinin-esterase and spike (S) envelope glycoproteins. The S glycoprotein is a primary coronavirus virulence factor responsible for both receptor specificity and membrane fusion-mediated entry into host cells. In addition, the S glycoprotein serves as a major antigen targeted by both the cellular and humoral immune responses and, as such, is an important target for antibody-facilitated virus neutralization. The objective of this research was the design of a safe and effective vaccine against BRCoV using a “prime-boost” vaccination approach. This method utilized an initial DNA vaccine encoding either the soluble …

The Effect Of Different Extenders On The Motility And Morphology Of Ram Sperm Frozen Or Stored At 4 °C, Recai̇ Kulaksiz, Çi̇ğdem Çebi̇, Ergün Akçay

Turkish Journal of Veterinary & Animal Sciences

This study was conducted to evaluate the effects on sperm motility and abnormality in ram semen extended with skimmed milk (M), sodium citrate (SC), Tris (T), and Bioxcell® (B) after storage in liquid form at 4 °C and in frozen form. Ejaculates were collected from 3 Akkaraman rams by artificial vagina twice a week during the non-breeding season. After pooling, each pooled ejaculate was split into 4 equal aliquots and diluted with skimmed milk (M), sodium citrate (SC), Tris (T), and Bioxcell® (B) extenders. Sperm motility was significantly higher (P < 0.05) in M compared with B, SC, and T on the first and second days (48 h) of storage. With regard to the percentage of total abnormal spermatozoa, the results in M were different from (P < 0.05) from those of SC and T on the first day (24 h) of storage but no different from B. Differences among extenders were found to be significant post-thawing for spermatozoa motility and the percentage of total abnormal spermatozoa. The total abnormality of semen diluted with M was significantly lower than that observed in the other extenders. Consequently, it was found that skimmed milk was better than the other extenders in terms of the sperm parameters evaluated during liquid storage and post-thaw.

Predator-Prey: Interactions Between The Spiny Waterflea (Bythotrephes Longimanus) And Pumpkinseed Sunfish (Lepomis Gibbosus), Jaime F. Leduc

Dissertations, Master's Theses and Master's Reports - Open

Small pumpkinseed sunfish ( Lepomis gibbosus), were found to be capable of removing the spine of Bythotrephes longimanus, an invasive cladoceran. Because fish consumption may be important in the dispersal or control of Bythotrephes, aquarium feeding experiments were conducted to 1) establish if the spine removal behavior of the pumpkinseeds was locally unique; 2) quantify how frequently pumpkinseeds exhibit the behavior; 3) determine if pumpkinseed handle Bythotrephes more quickly than other species of fish; and 4) verify if Bythotrephes' resting eggs pass through the digestive systems of pumpkinseeds in viable condition. The experiments revealed that pumpkinseeds (45-70 mm TL) from …
