The Effect Of Yucca Schidigera Powder Added To Lamb Feed On Fatteningperformance, Some Blood Parameters, The Immune System, And Theantioxidative Metabolism Of The Hepatic Tissue, Recep Gümüş, Hali̇t İmi̇k

Turkish Journal of Veterinary & Animal Sciences

In this study, Yucca schidigera powder (YSP) added to lamb feed was investigated for its effects on performance, some blood parameters, the immune system, and the antioxidative metabolism of the hepatic tissue. Throughout a 10-week fattening period, twenty-four 2.5-month-old male Akkaraman lambs were used. Three groups were established, including a control group © and groups YSPI and YSPII, which received a basal ration alone, a basal ration + 100 ppm YSP, and a basal ration + 200 ppm YSP, respectively. The groups did not differ for performance parameters (P > 0.05). While 100 ppm YSP increased serum NH3 levels (P < 0.05), 200 ppm YSP significantly decreased serum cholesterol, HDL, LDL, and Mg levels (P < 0.05). The groups did not differ for antibody titers against the Brucella melitensis vaccine (Rev 1). In groups YSPI and YSPII, hepatic CAT activity and LPO levels were significantly lower than those of Group C (P < 0.01). While the GSH levels of group YSPI were significantly higher than those of groups C and YSPII, the SOD activity of group YSPII was significantly lower than those of groups C and YSPI (P < 0.01). As a result, while YSP did not affect the performance parameters or immune system, it significantly affected NH3 levels, lipid metabolism, and the antioxidant system.

Cla And Epa Inhibit Lps-Induced Prostaglandin Release From Bovine Endometrial Cells Through An Nf-?B-Dependent Signaling Mechanism, Lokenga Badinga, Mehmet Şükrü Gülay, Alan Ealy

Turkish Journal of Veterinary & Animal Sciences

Although their action in antagonizing arachidonic acid metabolism is a key antiinflammatory effect of conjugated linoleic acid (CLA) and omega-3 polyunsaturated fatty acids (n-3 PUFA), these molecules have other antiinflammatory effects that might occur upstream of altered eicosanoid production. We examined the effects of two CLA isomers (c9,t11 and t10,c12 isomers), n-3 PUFA (EPA and DHA), and ΚNF-ΚB inhibitor (ammonium pyrrolidine dithiocarbamate (PDTC)) on lipopolysaccharide (LPS)-induced secretion of prostaglandins (PGE2 and PGF2a) by bovine endometrial (BEND) cells. LPS increased PGE2 and PGF2a concentrations in BEND cell-conditioned media in a concentration- and time-dependent manner. The c9,t11 CLA isomer and EPA decreased …

Effects Of Full-Fat Soybean Diet On Performance, Carcass Characteristics,And Fatty Acid Composition Of Hanwoo Steers, Sungil Kim, Jihong Lee, Sungkwon Park Jan 2016

Effects Of Full-Fat Soybean Diet On Performance, Carcass Characteristics,And Fatty Acid Composition Of Hanwoo Steers, Sungil Kim, Jihong Lee, Sungkwon Park

Turkish Journal of Veterinary & Animal Sciences

The effect of dietary full-fat soybean on performance and carcass characteristics of Hanwoo steers was investigated. Thirty steers (653 ± 52.96 kg) were allotted to control and full-fat soybean groups with a 210-day comparative feedlot trial. Steers were fed either the basal finishing diet (control) or control plus 5% full-fat soybean, using Calan gates for individual intake measurement. There was no difference in BW, feed intake, carcass weight, backfat thickness, loin muscle area, or meat color between groups. The average daily gain was greater (P < 0.05) in the soybean group compared to the control group. Steers fed soybean showed a lower feed conversion ratio than the controls. Marbling in the soybean group was greater (P < 0.05) than that in the control group. Supplementary full-fat soybean increased (P < 0.05) crude fat but decreased (P < 0.05) crude protein content in the longissimus muscle. Full-fat soybean increased (P < 0.05) total unsaturated fatty acids, including the levels of oleic, linoleic, and linolenic acid but, consequently, decreased (P < 0.05) total saturated fatty acids. Levels of conjugated linoleic acid, and its major precursor trans-vaccenic acid, were significantly increased by soybean supplementation. Our results demonstrate that full-fat soybeans may offer a better way to produce healthier beef with increased unsaturated fatty acids.

Gross Responses And Apparent Ileal Digestibility Of Amino Acids And Minerals In Broiler Chicken Fed Vegetable-Based Starter Diets Supplemented With Microbial Enzymes, Mohammad Abul Hossain, Paul Ade Iji, Al-Farooq Mohammad Fakhrul Islam

Turkish Journal of Veterinary & Animal Sciences

This study was conducted to investigate the effects of diet and exogenous enzymes on growth responses and micronutrient digestibility of broilers. Day-old broilers (n = 256) were distributed into a 2 x 2 factorial design and were fed on two basal diets: soybean (T1) or canola (T2) meals as such, or supplemented with enzymes up to 21 days. Feed intake (FI) and live weight (LW) to 21 days on the T2 diet was higher (P < 0.001) than that on T1. Feed conversion ratio (FCR) was better (P < 0.01) on T1 than on T2 at 21 days. Enzymes generally improved (P < 0.001) FI, FCR, and LW. The digestibility of histidine was higher (P < 0.05) on T2, but lysine digestibility was higher (P < 0.01) on T1 at 21 days. Histidine, threonine, lysine, valine, isoleucine, and phenylalanine digestibility was improved (P < 0.05) in the supplemented diets. Mineral digestibility was unaffected (P > 0.05) by diet, but enzymes increased (P < 0.05) digestibility of P, K, Mn, and Cu at 21 days. The digestibility of Cu, Zn, and Mg was higher (P < 0.05) on T2, whereas Ca digestibility was greater (P < 0.05) on the T1 diet. Broilers' growth responded positively to enzyme diets, probably due to improvement in nutrient digestibility.

Turkish Journal of Veterinary & Animal Sciences

Bovine milk, a rich source of proteins and fatty acids, has a beneficial impact on physicochemical and organoleptic properties. The current study was planned to identify oxytocin's effects on protein and fatty acid profiles of cow milk (the Sahiwal breed) at various lactation stages (early, middle, and late) under a controlled atmosphere and feeding inputs. Examination of milk protein and fatty acid profiles by urea polyacrylamide gel electrophoresis and gas chromatography-mass spectrometry respectively revealed the significant effect (P < 0.01) of oxytocin during the cow's lactation stages. In electrophoretic patterns, casein (αs1-CN, αs2-CN, β-CN, and k-CN) and whey protein fractions (Ig, BSA, β-Lg, and α-La) appeared as low-intensity bands in oxytocin-injected milk when compared to the control. Reductions in concentrations of fatty acids C16:0 (25.00%) and C18:1 (21.60%) were observed in oxytocin-treated milk as compared to the control group (29.30% and 29.10%, respectively) at late lactation.

The Nutritional Value Of Fecal Sacs: Testing The Parental Nutrition Hypothesis, Amanda W. Burns Jan 2016

The Nutritional Value Of Fecal Sacs: Testing The Parental Nutrition Hypothesis, Amanda W. Burns

College of Graduate Studies: Theses & Dissertations

Nest sanitation is an important aspect of parental investment in birds with altricial nestlings. Passerine nestlings produce fecal matter that is encased in a mucous membrane for easy disposal. These fecal sacs are either removed from the nest and transported a distance away or they are ingested by the adult. A decline in fecal sac ingestion rates as nestlings age has been observed in several species. The parental nutrition hypothesis posits that this pattern can be attributed to increasing digestive efficiency as nestlings age. The parental nutrition hypothesis makes three predictions: fecal sac consumption rates should decrease as nestlings age, …

Seasonal Habitat Selection Of The North American Porcupine (Erethizon Dorsatum) In A Coastal Dune Forest, Cara L. Appel

Cal Poly Humboldt theses and projects

Wildlife-habitat relationship studies are important for understanding the factors that determine where species occur in space and time. Habitat selection by generalist species should be studied on fine spatial and temporal scales to avoid masking important differences between seasons, localities, or orders of selection. I conducted the first study of habitat use and general ecology of North American porcupines (Erethizon dorsatum) in a coastal dune environment. Specifically, I assessed changes in body mass, home range size, and habitat selection in relation to the potential for seasonal nutritional and survival bottlenecks as reported elsewhere. Although they are considered generalists, …

Why Fish Do Not Feel Pain, Brian Key Jan 2016

Why Fish Do Not Feel Pain, Brian Key

Animal Sentience

Only humans can report feeling pain. In contrast, pain in animals is typically inferred on the basis of nonverbal behaviour. Unfortunately, these behavioural data can be problematic when the reliability and validity of the behavioural tests are questionable. The thesis proposed here is based on the bioengineering principle that structure determines function. Basic functional homologies can be mapped to structural homologies across a broad spectrum of vertebrate species. For example, olfaction depends on olfactory glomeruli in the olfactory bulbs of the forebrain, visual orientation responses depend on the laminated optic tectum in the midbrain, and locomotion depends on pattern generators …

Key (2016) claims fish that fish do not feel pain because they lack the necessary neuronal architecture: their responses to noxious stimuli, according to Key, are executed automatically without any feelings. However, as pointed out by many of his commentators, this conclusion is not convincing. Plants might provide some clues. Plants are not usually thought to be very active behaviorally, but the evidence suggests otherwise. Moreover, in stressful situations, plants produce numerous chemicals that have painkilling and anesthetic properties. Finally, plants, when treated with anesthetics, cannot execute active behaviors such as touch-induced leaf movements or rapid trap closures after localizing …

A Life Cycle Analysis Of Land Use In Us Pork Production, Greg Thoma, Marty Matlock, Ben Putman, Jasmina Burek

Food Systems

The goal of this study was to analyze land use in the production of US pork using Life Cycle Assessment (LCA). LCA is a comprehensive methodology for quantitatively analyzing potential environmental impacts associated with complex systems. Identification of processes contributing to high environmental impacts often highlights opportunities for gains in efficiency, which can increase the profitability and sustainability of US pork. The environmental impact category analyzed in this assessment was land use. After reviewing existing information regarding land use in agriculture and livestock production, analysis for US pork production was performed at two scales: cradle-to-grave and cradle-to-farm gate. The cradle-to-grave …
