Raising animals for fiber : producing wool from sheep, goats, alpacas, and rabbits in your backyard
Get a feel for fiber farming! Welcome to a \"wool\" new world! The perfect starting point, this book focuses on four different fiber animal species to tackle all of your questions and curiosities. Understand the basics of keeping livestock for fiber, then progress into detailed information on raising sheep, Angora goats, alpacas, and Angora rabbits to discover which could be the best fit for you. Learn tips for grooming, housing, feeding, shearing, breeding, and more for each animal, plus get ideas on how to use the fiber you harvest. Author and Californian fiber farmer Chris McLaughlin began from a simple curiosity that converged with her existing hobby of raising and showing rabbits. The same can go for you, too! An essential introduction to raising livestock for fiber ; Focuses on four main wool-producing animals: sheep, Angora goats, alpacas, and Angora rabbits ; Provides insight on each animal's fiber, as well as health, grooming, housing, breeding, shearing, and other special considerations ; Shares ideas on how to use and market the fiber you harvest ; Bonus fiber farming resources guide you to further research, such as national clubs, books, magazines, websites, and more. -- back cover.

Suspected Japanese Pieris
An alpaca housed in a zoo was suddenly found unable to stand, salivating heavily, and showing signs of distress. Despite receiving emergency medical care, including fluids and activated charcoal, the animal’s condition rapidly worsened and it died within a few hours. A detailed examination after death showed serious damage to the lungs and other organs. Plant material found in the stomach included leaves identified as Japanese pieris (Pieris japonica), a known toxic plant. Shrubs of this plant were also found inside the alpaca’s enclosure. This case highlights the risk of accidental poisoning from ornamental plants and the importance of careful environmental management in zoo settings.

Characterization and Evaluation of The Mechanical Properties of Blended of Yarns Based on Alpaca and Milk Protein Fibers
Purpose: The purpose of this study was to characterize and evaluate the mechanical strength of individual yarns as a blend of alpaca fiber and milk protein fiber. In addition, to obtain a product with a comfort factor suitable for textile applications.
Method: Different alpaca fiber diameters were used, such as alpaca huarizo fiber (AHF), alpaca superfine fiber (ASF) and alpaca baby fiber (ABF), and then mixed with milk protein fiber (MPF) to perform tests and methods, including the optical fiber diameter analyzer 4000 (OFDA 4000), tensile strength testing, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and Fourier transform infrared spectroscopy (FTIR).
Results and Discussion: In SEM observation, MPF showed a smooth morphology with areas of irregular grooves and protrusions, while AHF, ASF and ABF fibers showed a smooth surface with thin flakes. EDAX analysis revealed a chemical composition of C, N, O, Na and Si for MPF, while AHF, ASF and ABF presented C, N, O and S. By FTIR, specific chemical groups were identified. MPF showed amide I groups at 1647 cm-1 and amide II group at 1540 cm-1, confirming the presence of protein. AHF, ASF and ABF fibers presented at 1624 cm-1 the amide I band due to contributions from the C=O stretching vibration of the peptide skeleton, and at 1514 cm-1 the amide II group, arising from N-H bending and C-N stretching vibrations. The results of the comfort factor (CF) of AHF is significantly lower than that of MPF. Specifically, the CF of AHF was 38.15%, while that of MPF reached 99.69%. This indicates that, in terms of comfort, AHF does not equal MPF. Furthermore, when combining these fibers, the addition of MPF increases the CF, while reducing the diameter and the variability of the coefficient of variation (CV). Finally, in single yarn tensile strength tests, AHF demonstrated higher tensile strength, with a value of 63.3±4.9 MPa and a % strain of 6.98±1%, compared to ASF and ABF. However, MPF exhibited a maximum tensile stress of 67.2±4.9 MPa and a % strain of 11.71±1.3%, far exceeding AHF. In mixtures, the MPF-50%_AHF-50% combination showed a maximum tensile stress of 64.9±4.8 MPa, but with a low % strain, compared to the MPF-70%_AHF-30% mixture, which had a % strain of 10.39±1%.
Research Implications: The synergy between both fibers (alpaca yarns, blended with other natural fibres) not only seeks to improve the tactile experience of the garment, but also to contribute to the manufacture of more sustainable and environmentally friendly garments.
Originality/Value: This study contributes to the field of the textile industry by providing an alternative to the processing of textile fibers from the mixture of milk protein fibers and alpaca fibers. offering important knowledge for industry and academia.

Assessing the Longitudinal outcomes of Piperacillin/tazobactam versus ceftriAxone and metronidazole for Children with perforated Appendicitis
Acute appendicitis is the most common indication for emergency surgery in children. In cases of perforation, patients require post-operative intravenous antibiotics in hospital. However, some children fail to respond adequately, resulting in prolonged hospitalization. The optimal antibiotic regimen for perforated appendicitis remains uncertain. We propose a double-blind, randomized controlled pilot trial comparing two commonly used antibiotic strategies. Eligible participants include children <18 years undergoing laparoscopic appendectomy for perforated appendicitis. Following surgery, participants will be randomized to receive either: (1) piperacillin/tazobactam; or (2) ceftriaxone and metronidazole. The sample size for the pilot study is 16 participants (i.e., 8 per group). Feasibility outcomes include recruitment rate, protocol adherence, loss to follow-up, and cost per participant. This pilot study will assess the feasibility of conducting a blinded randomized controlled trial of postoperative antibiotic therapy in children with perforated appendicitis. To date, only one randomized trial has addressed this question, but it was limited by its single-center design, lack of blinding, and susceptibility to ascertainment bias and other methodological concerns. Findings from this pilot will inform the design of a larger, multicenter study with rigorous blinding and standardized outcome assessment to determine whether piperacillin-tazobactam or ceftriaxone and metronidazole provides superior outcomes.
