Great channel...
Indeed it should be a paid content at youtube, I have learned a lot of new things out of this lecture may ALLAH mian bless you more success ...
Ameen!!
classify feeds into
(1) roughages (2) concentrates
Roughages contain a high percentage of fibers.
Concentrates are the energy-rich grains and molasses, the
protein- and energy-rich supplements and byproduct feeds,
vitamin supplements, and mineral supplements.
19-arid-2252
Functions of feedstuff
Provide protein lips vitamin carbohydrates minerals water energy and also emulsify fats provide bulk reduce oxidation and also give flavor
In classification mainly fiber content provide business and recommend for ruminents while the chemical/digestible nutrients provide amount of nutrients that can be digested
Additives include non nutritive used to improve nutirent utilization like antibiotics harmonic plants falvouring agents.
19-Arid-2181
1- The main objective of classification of feed stuff is to avoid confusion in Identification as some feed stuff have different names in different countries so classification helps to identify feed stuff easily.
2- Main functions of feed stuff is to provide nutrients such as carbohydrates, lipids, proteins etc and also it modifies characteristics of diet.
19-Arid-2263
1. Learn about basis of classification includes botanical, autonomic, special purpose and others etc.
2. Learn about functions of feedstuff such provides nutrients as proteins, lipids, energy etc.
Modify characteristics of diet as emulsification, redox oxidation etc.
19-ARID-2285
1) roughages contain more fiber about 18% crude fiber. Mositur content in succulent roughages are about 60% while in dry roughages only 15%.
2) concrete stuff provide energy and protein to animals. Additives are used to enhance the nutritional worth of stuff.
19-arid-2200
1) Feed stuff gives the one or more than one nutrients or properties i.e proteins, carbohydrates, minerals, water
2) Feed stufff modify the characteristics of the diet i.e the emulsification of the fats, provide the flavours.
19-Arid-2202
1)In mineral /vitamin supplement in animal feed stuff we usually formulate diet the amount of minerals/vitamin available from feef stuff is excluded from the required value and rest is fulfilled by natural or commercial vitamin/mineral source.
2) Additive like harmone, antibiotics, pre and probiotics are non nutriative, they help in feed digestion , absorption and growth of individual etc. 19-ARID-2268
Additives are the non nutritional feedstuff that can be used to improve the growth, improve the worth of nutrition and keeping the quality of diet. It plays an important role in protecting the animals from diseases. For example antibiotics, hormones, probiotics and prebiotic etc.
19-ARID-2205
Feed stuff also provides one or more nutrients like protein, lipid, carbohydrates and minerals.
It also modify characteristics of diet. 19-Arid-2229
✓Additives are non- nutritive feedstuff but they're used to improve the nutrition worth of diet.
✓ The feedstuff that have high TDN (Total digestible nutrient value) they're considered as Energy feed stuff and good quality stuff.
✓ The aim for the feed classification is that they made identification easier and restricts confusion regarding names because sometimes the same feedstuff have different meanings in different countries.
19-Arid-2254
1- Classification for animal feed stuff used mainly depends upon the fiber content that are not utilized by the monogastric animal so it is suitable for ruminanat. It also depends on the chemical neutrients in the feed stuff that contains high TDM value.
2 - Succulent roughage contains 60% or more moisture while the Dry roughage contains 15% or less moisture.
19-arid-2182
Feed additives are non nutritive feedstuff used to improve nutrient utilization, feed intake of the animal and to improve shelf life the animal. Such additives include vitamins, hormones, mendicants etc.
Protein supplements are feedstuffs additives which are giving protein content of more than 20% to the feedstuff.
19-ARID-2198
1) Mode of propagation is also one of the basis of classification of feed stuff
2) Forages and roughages are low in net energy per unit weight usually bcz of high cell wall content .
19-Arid-2286
1) The total digestible nutrients present in the feed stuff also forms the basis of classification of animal feed stuff. The feed stuff with high TDN value will be highly digestible feed thus, proving to be a feed stuff high in energy and good in quality.
2) The main objective which lies behind the classification of animal's feed stuff is to make its identification easy by just knowing its assigned number.
19-ARID-2248
1.In pakistan crops are classified on the basis of seasons i.e karif and Rabi crops
2. Succulent roughages have moisture content above 60% whereas dry roughages have moisture content below 15%
20-ARID-381(A)
1. The high fibrous diet is usually not recommented for monogastric species while this high fibrous feedstuff is suitable for ruminants.
2. The chemical or nutrient composition indicates the Total Digestible Nutrients(TDN) in feedstuff.
19-Arid-2196
#1) Botanical classification means the classification that is done on the basis of the structure of feedstuff. This includes four classes, Tallophyta, Bryophyta, Pterido, and Spermatophyta.
#2)Pasture, green forages are the most used feed for the ruminants and it is either not cut or cut and fed fresh.
19-arid-2246
1.Additives are Used as growth promoters.example enzyme antibiotics etc .
2. We classify the feedstuff because it helps to identify the various crops
16-arid-2813morning extra enroll
19-ARID-2195
1. Forages like hay and roghages like PODS are low in energy because of low cell wall content.
2. Chemical composition shows the total digestible contents in animals while bulkness describes the fiber content which are mainly in ruminents.
Roughages have more than 18% crude fiber while concentrate have less than 18% crude fiber.
Additives are non nutritive feed stuff as they don't provide nutrition to animal but help in growth of individual and protect animal from different diseases.
19-Arid-2290
1.Mineral supplements and vitamin supplements are obtained either from the diet or given in pure element form to the animals.
2.Internationally every feedstuff has given a particular number which is used to determine which feedstuff is present in animal diet.
19-ARID-2239
Different feedstuffs have different names in different areas of the world...
The nutritional value of the feedstuff determines the energy quantity and quality of the feed.
There are about 8 classes of the feedstuff in the international scenario.
19-ARID-2309
Forages and roughages are low in net energy per unit weight usually because of high cell wall content. For example Hay,straw and stover.
19-Arid-2267
1. Botanical classification is done on the basis of structural characteristics of feedstuff which has 4 types i.e. Thallophyta (algae,fungi), Bryopyta (Mosses), Pteriphyta (Ferns), Spermatophyta (produce seeds).
2. Roughages have more fiber as compared to concentrates.
19-ARID-2240
✓ Feedstuff provides nutrients, proteins, lipids, minerals, vitamins etc. Moreover it also improves the nutrient utilization, improves feed intake, improves keeping quality of the stuff.
✓ Animal feedstuff is classified into 5 basic classes; Roughages (high in fiber, contains more than 18% of crude fiber), Concentrate (high in total digestible nutrients, contains more than 60% TDN while fiber is less than 18%), Mineral Supplements, Vitamin Supplements and Additives (non-nutritive feedstuff).
19-ARID-2187
Feed stuffs provide one or more nutrients or properties e.g. protein, lipids, carbohydrates etc. or it modifies characteristics of diet i.e. improve utilization of nutrients, improve feed intake and quality of stuff that are called food additives which can emulsify fats, reduce oxidation, provide bulk/flavors.
Feed stuffs can b rougages which conatin fibers which are of two types succulent fibers having above 60% moisture content while dry rougages have less than 15% moisture content. Concentrates are high in total digestible nutrients, fibers are less than 18%, energy concentrates are full of energy while protien suppliers called protien supplement concentrates having protien content more than 20%.
19-arid-2206
Feedstuffs, in addition to nutrition, also provide certain properties such as oxidation to the diet.
Feedstuffs can be classified as roughages, concentrate, vitamin supplements, mineral supplements, and additives
19-ARID-2257
1- Feed stuff also modifies characteristics of diet and improves nutrient utilization, feed intake, keeping quality of stuff and increases animal's shelf life.
E.g : fat emulsifiers and antioxidants etc.
2- Roughages are rich in fiber content and contains 18% crude fibers. On the basis of mositure, roughages are of two types :
i- Succulents (moisture content above 60 % )
ii-Dry (moisture content less than 15 %)
19-Arid-2287
Feedstuff provide nutrients such as proteins,lipids, carbohydrates,minerals,vitamins, water and energy.The modify characteristics of the diet are emulsify fats, reduce oxidation, provide bulk, and flavors etc.
Hamza Nazir
19-ARID-2282
Refugees are high in fiber and contain more than 18 percent crude fiber.
Additives are non-nutritive feed, they do not provide nutrition but they are used to improve the nutritive worth of diet.
19- Arid-2280
For nutritional point of view we classify Animal feed stuf into two main catogries
i) crude fiber contents
ii) total digestible nutrients
19-Arid-2284
1 animal feed have 5 classes
2 dry roughage have water less than 15 percent
19-arid-2208

All feed materials which are included in the animal ration or diet are referred to ad feeding stuffs. Classification of Livestock Feed. Animal feeds can be grouped into: Concentrates and Supplements: These are feeds for animals from which optimum production is expected, usually in a short time.
TDN (Total Digestible Nutrients) is a measure of the amount of energy that can be obtained from a unit quantity of the feed. ... - DCP (Digestible Crude Protein) is a measure of the amount of protein in the feed that can be digested and absorbed by the animal.
19-Arid-2204
DVM Morning Section A
Foodstuff helps in emulsification of fats. It also provide bilulk and flavor.
Various nutrients are also given by foodstuffs like protein, carbohydrates etc .
19-arid-2197
1.Classification is very necessary as it helps to indicate various plants as like food ,fiber etc.
2.Classification involves in the animal use feedstuff depends on the nutrient composition and fiber contents .
Reg No : 19-Arid-2318
3rd Evening ,Section :B
Feedstuff provided major nutrients like vitamins, minerals, water,
They also emulsify fats, reduces oxidations and also provides bulk, favor...
19_ARID_2209
Basis of classification
*we can classify feed crops on the basis of plants like annual, biannual and perennial and on the basis of photoperiod, climate.
*In Pakistan mostly feed crops are classified on the basis of their growing season like kharif crops are summer crops and Rabi crops are winter crops.
19-Arid-2251
1. Classification of feed stuff helps in the identification of related crop plants used for various purposes such as food,fiber etc that makes identification easier and their essential for orderly reference,and to avoid confusion in identification because sometimes the same feed stuff have different names in different countries i.e: the common example is "corn" or in some countries it is known as "maize".
2. There are different basis of classification of feed stuff:Botanical classification,Agronomic use classification,Special purpose classification.
19-Arid-2186
Classification for animal used food stuff
The fiber contents basically inficates the bulkniess of the diet and this is mainly recommended for ruminants animal feeding ...
19_Arid_2184
Those feeds they have high fiber content they are recommended for polygastric animals ...
19-Arid-4427 Morning
Function of feedstuff :
Feedstuff provides a large amount of nutrients E.g. proteins,lipids,minerals and carbohydrates to animal and majorily act as Energy source.
It usually modify characteristics of the diet for instance emulsify the fats and provides bulk.
Arslan Ahmad 19-ARID-2273 Evening.
Additives are not concerned with supply of nutrients but they improve the process of assimilation and digestion, hence increase in digestibility.
19-ARID-2272
1. Kharif and Rabbi crops are important crop classification in Pakistan along with botanical and agronomic classification method.
2. Roughages are widely used feedstuff due to cheap cost, easy availability, but has low energy value.
19-ARID-2264
DVM 3rd semester Evening
Section: B
The main purpose of classification of feed stuff is the identification of different crops used for feed purpose that is their fiber or protein content.
These feed stuffs may be classified on the basis of their structure, life cycle, season, climate, or special purposes such as silage, cover, green chops etc.
19-Arid-2224
1) Feedstuff have further classification .i.e. roughages , concentration , mineral supplement , vitamin supplement and additives .
2 )Feed ,in addition to the fulfill the nutrition requirements , also help in the oxidation of food etc.
19-arid-2276
Evening
1)-Protein supplements consist of product s which contain 20 percent of protein from animal origin.
2)-Classification of feedstuff for animals is based upon 1-Bulkiness (Fiber contents) and 2-Chemical/Nutrient composition.
19-Arid-4425
The function of feed stuff is:
To modify the characteristics of diet, improve nutrient utilization and feed intake etc.
To provide the body with one or more nutrients.
19-Arid-2290 (Evening-A)
Feedstuff provides one or more nutrient.
They modify the character of diet
Ansar Abbas
18-arid-4463
Morning A
Feed supplement is a feed that is rich in some specific nutrient, and fulfills the deficiency of that nutrient like vitamin supplements is fed to overcome vitamin deficiency whereas Feed additives are non nutritive feed stuff that fortify basic feed with essential nutrients like enzymes, hormones, pre-biotics and probiotics or other coloring flavors etc.
19-ARID-2236 (A)
The less fibre good having more concentration
The proper diet is assenctial for the growth of animal
19-arid-2227
Muhammad Moawiz
19-arid-2222
The main objective of classification of feed stuff is to avoid confusion in identification as some feed stuff have different names in different countries so classification helps to identify feed stuff easily.
1) Concentrates have 60% digestable nutrients.
2) Botanical classification is the most important basis of classification of feedstuffs.
19-arid-2192
Energy feeds: This includes the products with less than 20% proteins and less than 18% crude fiber or less than 35% cell wall( e.g Grain,mill by product ,fruit, nuts, roots and tubers. These are classified as energy feeds if these feeds are ensiled.
M. Ramzan(19-ARID-2307)
1-Feed additives are basically not nitrients but are used to enhance the energy of supplied nutrients and protect animal from different diseases....
2- More than 18 % of crude fiber is present in the roughes and are not useful for animal. Fibrous feed is not an energy source for monogastric animals because they contain high protein content not digested by animal....
19-Arid-2278...
There are five classes of animals feed.
Animals feed stuff depends upon the nutrients Composition.
Mujahid Fareed 19 arid 2235
There are five classes of animal feed.
Proper diet is essential for growth of animal.

Evening (3rd Semester)
Good feed is important for the better functioning of animals.
Identifying the feed which is more beneficial is another task.
19 Arid 2271
Function of foodstuffs :
(1)provides nutrients like proteins ,lipids carbohydrates and minerals
(2)Modify characteristics of the diet.
Animal used foodstuffs are classified into two
International feed classes have 8 more classes .
19-ARID-2319
Animal feedstuffs are classified on two basis a) bulkiness b)chemical nutrients
Internationally feed is classified into 8 classes.
19-Arid-2217 (morning-A)
The classification of feedstuff for the animal depends on the nutrient composition and fiber content.
Different foodstuffs has different names in different countries.Roughages has more than 18 percent crude fibers.
M.Shahbaz 19-Arid-2311
DVM Eve section A
Proper and balanced diet is important for the growth of animals.The animals should be provided with roughages, carbohydrates,proteins etc.
Rafia Bibi 19-Arid-2316
DVM Eve section A
Functions of feedstuffs include. 1- It provides more amount of nutrients for animals. 2- It increases the characteristics of the diet that is given to the animals. Basis of feedstuffs are. 1- Bullkiness or fibers content. 2- Chemicals or nutrients contents. 19-ARID-2262
1) Crude Fibers are high in fibers and are useful for ruminants.Not suitable for monogastric species.
2) Roughages have more than 18 Percent crude Fibers.
Energy Concentrates has less than 18 Percent crude Fibers and less than 20 percent protein content.
Protein Supplements have 20 or more than 20 percent protein (dry basis).
#19 Arid 2288
1-Roughage are fiber rich feedstuffs i.e. 80% fiber.
2-Concentrate has less amount of fibers.
19-ARID-2283
Indentification of different feed stuff helps to avoid confusion as same feed stuff has different name in differnet countries like corn is also known as maiz.
There are different sort of calssification of feed stuff on the basis of season, life cycle and on the structural basis.
19-arid-2292
The proper diet is essential for growth of animal
Main objective for classification of feed stuff is to avoid confusion
19-arid-2237
Feed stuff provides biochemical components like lipid protein and carbohydrates
Propagation of feed depend upon the feed stuff quality
19-arid-2211
The common of classfying the feed on the base of season.
1. Rabee crops
2. Khareef cropp
Function of feedstuff is to provide one or more nutrient..
19-Arid-2301
1. To identify the crops there are 6 types of classification. Botanical classification is the most important which based on the structural characteristics. In Pakistan most crops are classified on the basis of season.
2. Animal used feedstuffs are classified as:
* Bulkiness or fiber composition
* Nutrient composition
NOTE:
Feed which has high fiber components are more digestible and used for monogastric species or ruminants.
19-arid-2219
Feedstuffs can be classified on the basis of life cycle of the plant, season, climate, photoperiod,growing habit, mode of pollination, mode of propagation, mode of photosynthesis, nutrients uptake e.t.c
19-Arid-2183
Section: Morning (A)
1_ Main function of feed stuff is to improve the feed intake by adding flavours.
2-. in Pakistan the classification of feed stuff is mostly done by considering season .
19_arid_2212
We classify feedstuff because it helps us in the identification of related crop plants used for various purposes such as fibers, food.
2) it is also helpful for avoiding confusion in idenfication of feedstuff.
19-arid-2312
DVM evening
Section A
Classification for animal used foodstuffs:
1) The fiber contents basically indicates the bulkiness of the diet and this is mainly recommended for ruminant animal feeding.
2) Chemical or nutrient composition, that basically describes the amount of total digestible nutrients in a feed stuff.
19-Arid-2265
Life cycle of crops may be annual , Biennial & preannieal .
2. Their variety depends upon season like in pakistan i : Khari ...it is in Summer like from march to july .
ii :RABI :..winter & many others
19-Arid-2216
Energy feeds are rich in energy and the protein supplements are rich in protein as their content is 20% more protein.
19-Arid-2315
Fiber content in feed decides the bulkiness of the diet.
More concentration less fiber.
19-Arid-2261
Non nutritive additives are not of worth nutritional value but they help to improve utilization of nutrients in animals,or protect them from diseases or for various other purposes.
19-ARID-2199
Suitable feed is good for normal functionality of animals.... Fibre material shows diet bulkiness.
Less Fibre having more concentration
19-arid-2185
This practical is based on identification of feed stuff which will helps in identification of different plants used for different purposes. The identification can be based on botonical,agronomical and special purpose classification.
19-arid-4423
The stuff which contains high nutrient value they are termed as energy feed stuff or good feed quality stuff.
International feed classes are divided into 8 different claases
