Title: PERFORMANCE RECORDING


1
PERFORMANCE RECORDING Recording
System Recording in Dairy Cattle Beef Recording
2
Performance recording is a necessary
pre-requisite to effective decision making on
breeding policy. But to choice of recording
systems and type of records will differ with the
other uses to which they are put, e.g. the
monitoring of populations or herd level
management.
Explain the important of recording program in
the breeding management
3
Nonetheless, they should all take into account
the aggregate effects of the various traits of
productive significance and should provide a
characterization of the environment under which
the production is recorded.
4
Recording for national level decisions
In many countries, a fair amount of information
from institutional and commercial herds is
already available which should be analyzed before
introducing new schemes of recording. Recording
for the purpose of national decision making
should take into consideration the ecological
zones in which livestock are kept, the farming
system, whether nomadic, settled, small-holder or
intensive.
Explain the important of recording program in
the breeding management
5
Also the role of crops in the farming system, the
breed or breeds used and the problems of disease,
adaptation and survival in each breed /production
system combination.
The initial step usually involves surveillance
studies designed to obtain baseline data on
productivity parameters and on the constrains to
increased productivity.
6
In the simple form, they consist of interviews
of chosen farmers conducted by selected personnel
to obtain approximate parameters of birth,
growth, production, mortality, etc., (Ellis,
1980).
Explain the important of recording program in
the breeding management
7
A representative sample of farms and animals in
each combination of ecological zone, production
system and breed should be chosen and, if any
development project is being implemented, the
response of traditional farmers to the
developmental process should also be recorded.
The total number of animals in the survey could
be a few thousand.
8
The next step involves the regular monitoring of
the performance of particular populations over a
given period of time. The herds chosen should
be representative of the different production
systems and the monitoring should relate to herd
structure, fertility, mortality, and disposal,
health and productivity.
9
An important aspect of the monitoring process
should be the study of livestock development
programs. Such programs area essentially
large-scale experiments which cannot be
reproduced within more conventional research
programs and can therefore provide invaluable
information on the response to environments.
Explain the important of recording program in
the breeding management
10
Where such development program do not operate, it
may be necessary to introduce improvements in
some herds as part of the monitoring program in
order to provide this information
11
Herd level recording Performance recording of
individual animals is usually associated with
selection for genetic improvement. However,
such recording may be even more important for
management decisions.
Explain the important of recording program in
the breeding management
12
In the initial stages of introduction of
recording scheme, emphasis should be on immediate
benefits that could be derived from management
changes, e.g. more surviving progeny or an
increase in saleable produce.
Explain the important of recording program in
the breeding management
13
Cooperation between the farmer and the field
recorder is a basic requirement for the
successful operation of any recording scheme.
This cooperation cans only come through an
understanding of the use of records.
Why does recording scheme should be capable of
performing educational role, not merely service
one ?
14
The recording scheme should therefore be capable
of performing educational role, not merely a
service one.
Why does recording scheme should be capable of
performing educational role, not merely service
one ?
15
Recording in the tropics The transfer of
recording systems used in temperate countries to
the tropics has in most cases proved
impracticable. No standard system of recording
can be devised that is suitable for all farming
conditions.
16
The level of recording that is possible depends
on the kind of management adopted and the stage
of development of the livestock industry.
With large flocks reared extensively under
nomadic conditions, the identification of animals
with good fertility and longevity may be all that
is possible.
17
Recording is thus an evolutionary process and
advances can be made only when there is progress
in levels of husbandry. At every stage, it is
important that no more than the essential records
are maintained.
18
This is necessary not only because of
inadequacies in the educational level of
livestock farmers in the tropics but also due to
the lack of qualified recorders to operate more
sophisticated systems. A further reason is the
inverse relationship between the rate of genetic
progress and the number of traits for which
selection is practiced.
19
Optimum deployment of recording systems therefore
requires that it be limited to traits, which can
be measured easily, and with a high degree of
accuracy and which have an economic value. In
most tropical countries, large herds are kept in
governmental and research institutes to serve as
sources of superior male breeding stock.
20
The recording done in these herds may involve
extensive written records. In privately owned
herds, the type of information that can be
extracted depends on the farming systems.
21
For example, although it is futile to attempt
recording milk yield or growth rate in nomadic
herds, they can nevertheless provide valuable
information on longevity and reproductive
performance under conditions of nutritionalstress
and disease challenge.
22
Simple procedures (e.g. ear notching) can be
adopted to place animal in different performance
categories.
This would aid in the selection of progeny that
can then be subjected to further tests in testing
stations or institutional herds. The chief
advantage of nomadic herds is their large size,
which could allow high selection intensity.
23
In contrast, sedentary herds, despite their
accessibility to recorders and the facility they
provide for recording more traits, have the
disadvantages associated with small size. Any
performance recording system in the tropics must
satisfy number criteria if it is to be effective.
24
1) The system must be simple, i.e. involve little
paper work for the farmer. It should not require
major alterations in his farming routine. 2) The
traits should be economically important and the
resulting products should be either marketable or
consumed by the producer. Their number should be
kept as low as possible. Information extracted
should also aid in management.
Explain. How is the way recording program in the
tropic will be effective ?
25
3) The system should be efficient in terms of
time and cost. 4) The records should make it
possible to identify the best and poorest animals
at the farm level and genetic differences between
populations at the national level.
Explain. How is the way recording program in the
tropic will be effective ?
26
RECORDING IN DAIRY CATTLE Milk recording
practices The usual practice in milk recording is
for milk and butterfat to be estimated from a
limited number of measurements made at-intervals
throughout the lactation. The longer the interval
between these measurements, the greater the error
of the estimates is likely to be.
27
When the interval is shorted, the expense of
recording is increased, so that in practice a
compromise is made between the needs of accuracy
and economy.
What is practical recording system in developed
countries you are suggest ?
28
Generally, milk recording in the developed
countries has involved the weighing and sampling
of the milk produced by individual cows on farms
that are visited by official recorder at
intervals of 3-4 weeks throughout the year.
Explain. How is the way recording program in the
tropic will be effective ?
29
Morning and evening milk yields are recorded and
composite samples of the two are taken for fat
(and protein) determination. With the
increasing cost of recording, there is a trend
now towards the farmer doing his own recording
(Lindhe, 1980).
Explain. How is the way recording program in the
tropic will be effective ?
30
Monthly records may not be sufficiently elastic
to meet the requirements of herd owners whose
primary interest is in using the records for
feeding and management.
Why is the monthly records may not meet the herd
owners requirements ?
31
They are therefore encouraged to make entries of
production at more frequent intervals - weekly or
even daily.
Why is the monthly records may not meet the herd
owners requirements ?
32
Problems of milk recording in the
tropics Institutional herds in the tropics can
adopt the same procedures of milk recording used
in developed countries. Similar practices can
also be used in large private herds.
What is the most problem of milk recording in the
tropics ?
33
However, a large proportion of dairy cattle in
the tropics is owned by small farmers and it is
here that the problem of milk recording lies. The
major constraints are the small average herd
size, poor communication and lack of incentives
for recording. Other possible reasons are
inadequate appreciation of the value of progeny
tested sires, low educational level of farmers
and lack of qualified recorders.
What is the most problem of milk recording in the
tropics ?
34
Where AI services are relatively undeveloped, the
value of a recording service may be questioned.
However, even in such situations, recording can
assist in the culling of unproductive females in
addition to aiding in herd management.
What is actually aid the herd management which
came from recording practice ?
35
When introducing a milk recording scheme, certain
incentives may have to be provided to encourage
farmers to cooperate, e.g. free veterinary care,
advice on management and feeding, low cost
AI. It may even be necessary to pay a fee to
farmers who cooperate in recording daughters of
bulls used in progeny testing.
36
Alternatives to official record-ing in the
tropics The main costs of milk recording are the
recorder's salary and expenses. These tend to be
high in the tropics because of the small size of
herds, their scattered distribution and the need
to include a large number of herds and cows to
facilitate progeny testing.
37
Different methods can be adopted to overcome the
financial stress of recording. There could be a
reduction in the number of visits paid to each
farmer, so that the recorder may cover more herds
and cows.
38
Recorders may also be employed on part-time basis
and could undertake other work as well. Thus, AI
personnel car be trained in recording work and
may serve as part-time recorders. This has
particular application in the tropics. In
countries with organized AI services and where AI
personnel make daily rounds it may be possible to
arrange their routine so that they call on one or
more farms daily for milk recording.
39
The technician need not do the milk recording
him-self but could provide the farmer with a
recording device and on the following collect it
from him together with the milk records. It
would of course be necessary for the technician
to be present when the recording is done for the
first time to demonstrate the procedure.
40
In situations such as the above, where it is not
possible to have the services official recorders
except perhaps in a supervisory capacity, an
owner sampling system can be introduced. Here,
the farmer does the routine weighing him-self,
periodic visits are made by the official
recorder.
41
The measuring equipment use by the farmer could
be very simple. It may be plastic buckets or
bottles pre-marked into ½ kg sections by the use
of exact measuring equipment.
42
Milk composition In many tropical countries
where milk is consumed primarily for its protein
and not for fat, testing for butterfat content
may not be necessary. However, bulk milk
samples may be tested for fat content to assess
the overall herd situation in instances where the
price of milk is determined by its fat content.
What the milk compositions are important to be
measured and why are these important to be
measured ?
43
If it is necessary to know the fat composition of
milk from individual cows, monthly testing of
samples taken during the course of the lactation
is adequate.
What the milk compositions are important to be
measured and why are these important to be
measured ?
44
Protein content is usually determined from fewer
samples -four samples taken during a lactation
being adequate (Lindne, 1980). Semi-automatic
machines for quick determination of protein
content are now available which make it possible
to analyze a large number of samples at a central
laboratory. A preservative such as potassium
dichromate should be added to the samples before
dispatches the laboratory.
45
Sample for milk composition testing should
preferably be taken by official recorders to
ensure proper sampling procedures. Usually a
composite sample proportional to the yield at
the two milkings is taken for testing purposes.
46
Testing for milk composition requires more
organization and a dependable communication
system. Be that as it may, the importance of
milk yield as a selection criterion far outweighs
that of milk composition.
Which is more important as selection criterion,
is that milk yield or milk composition ?
47
Hence, non-availability of facilities to test for
milk composition should not stand in the way of
implementing a milk recording program.
Which is more important as selection criterion,
is that milk yield or milk composition ?
48
Alternatives to month recording 1) Bimonthly
recording In this system, the recorder visits
the farm every alternate month and records the
yield obtained during a 24-hour period. The
percentage of large errors of individual cow
records in bimonthly recording is higher than
with monthly testing but its level of accuracy is
adequate for progeny testing purposes.
Explain the alternatives to month recording
49
2) A.M.-P.M. sampling. In this method, the
morning milk is weighed one month and the evening
milk the next month. It is more accurate than
bimonthly testing but less accurate than monthly
testing. Its chief advantage is that it is
cheaper than monthly testing but maintains the
same frequency of visits to the farmers.
50
3) Sampling at particular stages of lactation.
The total yield estimated from monthly records is
moderately correlated with the yield obtained on
a single day during the third to the sixth month
of lactation (Lindstrum, 1976). This has led to
the suggestion that a reasonably accurate progeny
test of bull could be retained from such records
if large progeny groups are available.
51
For example, a progeny test based on a single
day' s record of 100-150 daughters would be as
accurate as a progeny test based on about 35
daughters with complete records. However, this
system would be difficult to implement in herds
calving year round since the cows will be
indifferent stages of lactation when the recorder
visits the farm. But if the farmers provide the
data or if AI personnel are involved in the
recording, it should prove workable.
52
The methods used in estimating total lactation
yields depend on the recording system. The
centering method of calculating yields is
preferable to other methods in monthly recording.
In this procedure, the test day yield is
multiplied by the number of days in the period of
which it is the center, and these products are
summed to give an estimated lactation yield.
53
At the beginning and end of lactation, the test
day will not necessarily be the center day of the
test period the first test period runs from
four days after calving to the beginning of the
following period, and the last period runs from
the en, of the preceding period to the end of the
lactation.
54
In general, fortnightly recordings are required
for individual cow selection. Monthly recording
gives reliable information for sire proving, but
bimonthly or A.M -P.M. methods may be used if a
slight loss of accuracy is acceptable. If used
as an aid in management, particularly in deciding
on feeding levels, recording week1y or at more
frequent intervals may be required.
55
The problem of milk letdown in zebu herds Many
zebu cows do not let their milk down unless the
calf is allowed to suck This problem is partially
overcome by allowing the calf to suck for a very
short period to induce milk let-down followed by
hand milking. This process of stimulation of the
dam by the calf and milking may be repeated if
necessary until all the milk has been drawn.
56
In using this method, the calf should be
separated from the dam for the period intervening
between P.M. and A.M. is milking otherwise the
first record taken in the morning will be
erroneous.
57

Other records Apart from yield and composition,
other traits are also important in the
tropics. In most zebu breeds milk yields and
lactation length are strongly correlated
(Mahadevan, 1966).
58
Lactation length than be used as an indirect
selection trait in situations where yield is not
measured, e.g. in nomadic herds. Age at first
calving and calving interval can be readily
measured and are important indicators of
adaptability to stress conditions.
59
Records on the farm and pro-duction summaries In
most farm situations in the tropics, the
individual cow record is the only one that needs
to be kept by the herd owner. Lactation
summaries, calving and breeding records and calf
identifi-cation would be the responsibility of
the official recorder.
60
A summary based on the data collected on the test
day should be sent to the farmer shortly after
the test to enable him to take the necessary
management decisions. These should include 1)
the test-day lactation report showing each
animal's milk production and total production to
the last test day and 2) a herd summary giving
information on animals for breeding, pregnancy
checking drying and culling during the next 30
days.
61
The latter report should also give the means of
milk yield, composition and calving intervals
animals that completed lactation during the last
12 months.
