The semen, which is deposited into the cow, has been previously harvested or collected from a donor bull. The semen is then prepared and placed in liquid nitrogen for storage until use

Why do dairy farmers use artificial insemination?

Farmers aim to use a balanced breeding method to improve the productivity, health qualities, fertility, and lifespan of their dairy cattle. Dairy farmers benefit from artificial insemination (AI) in a variety of ways, including access to the best genetics, improved animal health, and the safety of farm workers.

How can artificial insemination be used to improve fertility of bulls?

Good sires that have lost the capacity to breed naturally can be made to donate semen. Oversized or short bulls can also be exploited for their genetic potential through AI. The female genitalia can be examined and then AI can be done to ensure fertility. Sexual health can be guarded.

What are the pros and cons of artificial insemination for cows?

When farms relied on bulls for the majority of their reproduction, the bulls were actually milked alongside the cows in the milking parlor. This means milkers had close contact with an animal twice a day, which could kick them in the head at any time. This risk is entirely eliminated using artificial insemination. 2. Cow Safety

Can you do AI through the cervical rings?

A properly timed procedure should allow for relative ease in manipulating through the cervical rings. However, young or maiden does will prove markedly more difficult and are not advised for the beginning technician. Even well seasoned does, if stressed or made uncomfortable due to rough handling or poorly designed or ill-used equipment, can become so tense as to constrict the muscular canal of the cervix rendering its penetration past the os nearly, if not totally, impossible. It cannot be overstressed that AI should be performed with a slow, determined, but gentle approach with adequate time allowed to follow proper protocols.

Some indicators of breeding readiness are age, breed, nutrition and management , displaying signs of heat and reproductive tract maturity.

How to know if an animal is ready to breed?

Signs of heat could include mounting, vaginal discharge, pacing, use of a detection patch just to name a few. When these signs are recognized, the animals are exhibiting that they are ready for breeding. Cattlemen should ride their herds at least twice a day for heat signs. When signs are recognized, those animals should be bred 12 hours later. The AM/PM rule follows this philosophy. If you see an animal in heat in the morning you should breed in the afternoon and vice versa.

Syntactic Analysis

The first question that is bound to be asked by everyone is, What exactly is Syntactic Analysis? Syntactic analysis is described as the study of the logical meaning of specific phrases or portions of sentences.

About Parser

We already know parsers are used to implement parsing, but what is the definition of a parser? It is described as a software component meant to take input text data and provide a structural representation of the data after validation for correct syntax using formal grammar.

About Grammar

Parsing is done to analyze the grammar of a sentence, so we must have a basic idea about the concept of grammar. To explain the syntactic structure of well-formed programs, grammar is highly significant. They imply syntactical norms for dialogue in natural languages in the literary sense.

Syntactic analysis vs Lexical analysis

The main difference between syntactic analysis and lexical analysis is that lexical analysis is concerned with data cleaning and feature extraction with techniques like stemming, lemmatization, correcting misspelled words, and many more.


NLP is getting more and more popular every day as it has many applications like chatbots, voice assistants, speech recognition, and many more. Syntactic analysis is a very important part of NLP that helps in understanding the grammatical meaning of any sentence.

How can AI help?

Using the correct techniques when performing artificial insemination (AI) can help ensure success while minimizing risk of injury to the technician and the animal. Becoming proficient at performing AI takes adequate training, knowledge, and repetition.

Can AI catheters be moved?

It does not take much force to move the AI catheter through the reproductive tract. Avoid applying too much forward pressure with the catheter, as this should be unnecessary and could cause irritation or injury. Vaginal folds will often cause resistance and prevent the catheter from proceeding easily into the tract. If you believe the catheter is stuck in a vaginal fold, manipulate the reproductive tract with your palpating hand as described below while readjusting the direction of the catheter.

What is artificial insemination?

Introduction. Artificial Insemination (AI) is an Assisted Reproductive Technology (ART) used worldwide to deposit stored semen directly into a cow or heifer’s uterus. It is a tool for improving reproductive performance and genetic quality of livestock.

What is needed for an insemination kit?

The basic insemination kit should contain a stainless-steel AI gun, straw cutter or scissors, tweezers, non-spermicidal lubricant, thermometer, and thaw unit (water bath or wide-mouth thaw thermos). In addition, disposable supplies like split plastic sheaths, sanitary covers, plastic palpation gloves, and paper towels (Figure 1). The AI kit must be stored in a dry, dust-free, clean place. It is important to clean the kit before and after performing AI.

How did genetic improvement affect dairy bulls?

This led to the use of good bulls for upgrading and crossbreeding. Further, the AI made it possible to assess the bull in a very rigid situation and pick up a few outstanding bulls for propagation.

What should a technician know about semen?

The technicians should be good at evaluating the semen and should know the importance of temperature, pH, etc. Genetical problems: The introduction of AI has put into use sires that pass dairy traits especially those associated with the quantity of milk and certain qualities.

How is milk regulated?

Dairy industry: Research in the areas of genetics and breeding indicated that quality and quantity of milk can be regulated by selective breeding and inter-se mating. Through AI these can be scientifically followed, quickly propagated, and properly evaluated. Bulls have been evaluated not only for confirmation and total milk yield but also for the percentages of fat and protein.

Is AI in heat bad?

AI at early and late heat is unfruitful. It causes infections in cervix and uterus, and puts animals on repeat breeders list AI in post-insemination period should be done after a very careful examination or else one risks infections, early embryo mortality or abortion (this is known to occur when AI is done in the gestational heat).

Is heat detection needed for AI?

Heat detection: Very efficient heat detection is required to make AI a success. Though anyone symptom or more than one (that is useful to track a female) is employed, still man is a poor detector of heat than the male of the species.

Is AI good for dams?

Breeding difficulties: AI gives a good scope to use a sire for many dams, but it does not serve to solve many breeding problems. Poor collection, preservation, transport, and error in judging the heat before insemination upset any such advantage offered by the sire fertility. Hence overall gain is as good as natural service or in certain cases lower than that.
