INFERTILITY IN MALE ANIMALS.pptx
This document discusses infertility in male animals. It begins by describing the normal mating behavior and duration of copulation across different species. It then discusses various causes of infertility, including conditions that prevent normal service like problems with erection or lesions on the penis. It also discusses conditions that allow for normal service but prevent conception, like issues with the testes or sperm defects. Specific diseases and defects that can cause infertility are described in detail throughout the document.
Hereditary and genetic diseases
This document discusses several genetic diseases that affect cattle, buffalo, sheep, goats, chickens and pigs. It describes the inheritance patterns and key clinical signs of various conditions like chondrodysplasia in cattle, osteogenesis imperfecta in cattle, dermatosparaxis in sheep, afibrinogenemia in goats, and splayleg in pigs. Strategies to control genetic diseases include preventing breeding of carriers, screening breeding stock, early diagnosis, and developing DNA tests to identify diseased animals.
IMPOTENTIA COEUNDI.pptx
This document discusses various causes of impotentia coeundi (inability to copulate) in male animals. It covers conditions like gonitis, coxitis, balanoposthitis, phimosis, paraphimosis, priapism, and ruptured penis that can damage joints or genitals and prevent successful mating. Surgical correction or extended sexual rest may help treat some physical issues, while others like short penis may be untreatable congenital conditions.

The congenital fetal defects in cattle and other species are described in this lecture. Useful for veterinary students, practitioners, and researchers
Spermatogenesis
Spermatogenesis is the process by which sperm are produced in the testes. It begins at puberty and takes approximately 74 days to complete. It occurs in the seminiferous tubules of the testes and involves the transformation of spermatogonia stem cells through meiosis into mature sperm. Sertoli cells provide nourishment and structural support during spermatogenesis. Hormones such as testosterone and FSH control spermatogenesis. Abnormalities in spermatogenesis can lead to male infertility.
Equine genetic disorders
The document discusses several genetic disorders that can affect horses, including both lethal and non-lethal conditions. Some lethal disorders discussed include Overo Lethal White Syndrome, Glycogen Branching Enzyme Deficiency, and Lavender Foal Syndrome. These disorders are usually fatal within the first few days or months of life. Some non-lethal conditions mentioned include Equine Juvenile Epilepsy, Guttural Pouch Tympany, and Hairless Foal Syndrome. These conditions do not always result in death but can cause health issues. The document provides details on the inheritance and symptoms of several example disorders.
Testicular feminization syndrome
This document discusses testicular feminization syndrome (TFS), also known as androgen insensitivity syndrome (AIS). TFS is caused by mutations in the androgen receptor gene that result in partial or complete inability of cells to respond to androgens. This leads to undervirilization or feminization of genetic males. The document classifies AIS into three classes based on severity of symptoms: complete AIS, partial AIS, and mild AIS. It provides details on genital embryology, expected phenotypes for each class, differential diagnoses, and epidemiology estimates.

The document provides a high-level classification of genetic disorders and summaries of common syndromes associated with chromosomal anomalies.
Pedigree presentation
Based on the information provided, here are my responses:
- The inheritance pattern shown in this pedigree is autosomal recessive. Cystic fibrosis is caused by mutations in the CFTR gene and follows an autosomal recessive pattern of inheritance.
- III-1 is likely a carrier (heterozygous for a CF mutation). His wife is unlikely a carrier.
- III-2 and II-3 are also likely carriers since they each had an affected child but are unaffected themselves.
- The odds that IV-5 would have an affected son is 25% since each parent is a carrier. There is a 50% chance they would pass on a CF mutation to each child and a 25% chance both would

Ovarian Cysts
This document discusses ovarian cysts in cattle. It begins by defining ovarian cysts as fluid-filled sacs arising from the ovary that are usually over 25mm in diameter. The two main types of physiologic ovarian cysts are follicular cysts, which form when a follicle does not rupture to release an egg, and corpus luteum cysts, which form if the corpus luteum does not dissolve after ovulation. Pathologic cysts can cause pain, infertility, or torsion of the cyst. The document then discusses various types of pathologic cysts and differences between benign and malignant ovarian cysts in cattle. Treatment options for follicular cysts in cattle include GnRH or PGF2α to induce ovulation or
SexLinkage2.ppt
The sex of an individual is determined by the sex chromosomes contributed by the sperm and egg, with the sperm determining whether an X or Y chromosome is donated. Thomas Morgan studied sex-linked inheritance in fruit flies and discovered that eye color was located on the X chromosome. Some traits are located on the sex chromosomes and their inheritance depends on the parent's sex. Many known sex-linked traits are X-linked due to the X chromosome's larger size. Examples of sex-linked disorders include hemophilia, color blindness, and Duchenne muscular dystrophy.
Genetic disorders in cattle
Genetic disorders can cause economic losses in cattle. There are two main causes of genetic disorders: environmental and genetic. Environmental causes are easier to address by removing the environmental factor, while genetic causes are more complex as they are inherited. Some common genetic disorders seen in cattle include atresia ani, umbilical hernia, hypotrichosis, alopecia anemia, epitheliogenesis imperfecta, syndactylism, arthrogryposis, osteopetrosis, arachnomelia, weaver syndrome, spinal dysmielination, and parakeratosis. The presentation provides details on the causes, clinical signs, and characteristics of each of these genetic disorders.
Klinefelters,turners,intersex- Dr.Gourav

ANAMOLOUS SECONDARY GROWTH IN DICOT ROOTS.pptx
Abnormal or anomalous secondary growth in plants. It defines secondary growth as an increase in plant girth due to vascular cambium or cork cambium. Anomalous secondary growth does not follow the normal pattern of a single vascular cambium producing xylem internally and phloem externally.
Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Nucleophilic Addition of carbonyl compounds.pptx
Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general.
Carbonyls undergo addition reactions with a large range of nucleophiles.
Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen.
Electronic effects (inductive effects, electron donation) have a large impact on reactivity.
Large groups adjacent to the carbonyl will slow the rate of reaction.
Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.

Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Lecture 6 Male infertility.pptx
- 1. Course: Andrology and Male infertility Lecture 6: Male infertility Dr. Farooz Ahmad Lone (Ph.D Gold Medalist) Assistant Professor Animal Reproduction
- 2. Male infertility Forms of infertility • Impotentia coeundi is the reduced to complete lack of sexual desire and ability of male to copulate. • Impotentia generandi is defined as the inability or reduced ability of a male to fertilize after normal service. Impotentia coeundi (causes) • Lack of libido • Failure of erection • Diseases of joints, muscles, nerve, bone, and tendons “In young bulls that are more enthusiastic for mating, the lumbo-dorsal fascia may rupture, producing the so-called condition of ‘honeymoon back’.” “Spastic syndromes (progressive hind limb paralysis)”
- 3. • Tumour of the penis and prepuce “Squamous cell carcinoma of horses, fibro-papilloma of bulls and transmissible venereal tumour TVT) of dogs.” [TVT is also called infectious sarcoma, venereal granuloma, transmissible lympho-sarcoma or Sticker tumor] • Diseases of the penis and prepuces Rupture of the corpus cavernosum penis (broken penis)- common in bulls Persistence of the penile frenulum: During erection, ventral bending of the penis occur in affected animals.
- 4. Deviation of the penis (Phallocampsis) Spiral or corkscrew (slipping of apical ligament, counter clockwise, common in bull) Ventral or rainbow deviation (ligament is thin and stretched) S-shaped deviation (short apical ligament with long penis) “Fascia lata implant technique is used for repair of both spiral and ventral penile deviation” Balanoposthitis • Balanoposthitis is an inflammation of the glans penis and the prepuce. It is common in the dog, bull and ram, occasional in the stallion, and rare in the boar and cat.
- 5. Pizzle rot, Phimosis, Paraphimosis, Diphallus, Priapism Hypospadias and epispadias Impotentia generandi With apparently normal semen a) Inherited sperm defects • Diadem defect, Knobbed sperm, Enzymatic disturbances • Chromosomal defects b) Infectious diseases With apparently abnormal semen Cryptorchidism, Inguinal hernia, Imperfect testicular descent, Testicular hypoplasia, Testicular degeneration, Testicular fibrosis, Testicular neoplasm, Epididymitis, Spermiostasis, Segmental aplasia, Pathology of accessory glands, Congenital defects, Scrotal torsion, Orchitis, Testicular calcification
- 6. Balanoposthitis • Balanoposthitis is an inflammation of the glans penis and the prepuce. It is common in the dog, bull and ram, occasional in the stallion, and rare in the boar and cat • IBR–IPV Q. No. 11: The most serious cause of balanoposthitis in the stallion is: • Dourine (Trypanosoma equiperdum) • Surra (T. Evansi) • Contagious equine metritis • Equine coital exanthema
- 7. Pizzle rot • Pizzle rot or ulcerative posthitis is principally a disease of sheep but occasionally is seen in goats and cattle. high-protein diet & Corynebacterium renale • Phimosis is the inability to protrude the penis beyond the preputial orifice. • Paraphimosis occurs when the penis protrudes from the preputial sheath and cannot be replaced to its normal position. The condition is most common in the dog and the stallion. • Most male tortoiseshell cats are infertile. Male tortoiseshell cats with the chromosome complement of 39, XXY are infertile because the extra X chromosome in spermatogonia blocks spermatogenesis and such animals are known as Klinefelter cats.
- 8. • Scrotal circumference measurement of less than 30 cm in post pubertal bull has been considered for testicular hypoplasia in the bull. Species Difference between X and Y DNA • Cattle 3.8% • Sheep 4.2% • Pig 3.6% • Dog 3.9% • Horse 4.1% • Rabbit 3.0% • Human 2.9%
