A
2.70 kg
3
Q
top 5 producing regions
A
- Ilocos
- southern tagalog

- northern mindanao
- western visayas
4
Q
beef production systems in the Philippines (2)
A
- ranching or extensive system
2. feedlot fattening operation
5
Q
2 operations under ranching or extensive system
A
- cow-calf operation
2. purebred program or breeder farm operation
6
Q
aim to produce stockers and feeders;
initial and most fundamental step in the beef enterprise is the production of the claves and raising it to weaning age
A
- cow-calf operation
7
Q
Aim is to produce breeder stocks to be sold to other ranchers;
highly specialized form of beef production
A
- purebred program or breeder farm operation
8
Q
the objective is to add weight to the animal and increase its value
A
- feedlot fattening operation
9
Q
three main reasons why feedlot fattening operation is important to the livestock industry of the Philippines?
A
- provides farmer extra income
- gives him year-round work and allow the use of cheap, plentiful farm by-products such as corn stovers, hay, silage, rice straw, copra meal, rice bran and sugarcane top w/c might otherwise wasted
- helps meet the urgent demand for high-protein foods in filipino diet
10
Q
percentage of backyard sector
A
92% of total cattle production
11
Q
backyard cattle raising is characterized by:
A
- 1 or 2 heads of either fattening or breeding cattle is raised on farmer’s spare time
- tethers animal to graze, then supplements this w/ farm wastes like rice straw or corn stovers/stalks
- practice of soiling and supplementing w/ ipil ipil as a source of protein, and rice bran, corn bran, or cops meal at 1-2 kg/ animal
- in batangas, force feeding (supa or supak) of feed mixture is a common practice among backyard cattle raisers

the most impact was carried through the brahman thriugh the pioneering of efforts of?
Mr. Antonio Nocom of Ansa farms of tiboli;
Tantangan in South cotabato and Lipa, Batangas;
sarangani cattle owned by the Consunji's
41
brought cattle to the new world
christopher columbus and others

43
the controlled propagation of cattle to improve qualities desirable to man
breeding
44
traits in w/c there is a sharp distinction between phenotypes;
usually, one or few pairs of genes are involved in the expression this traits.
SHOW DISCONTINOUS VARIATIONS
Qualitative traits
45
show continous variations between the extremes, because the trait is the sum of several effects caused by the gene
Quantitative traits
46
Qualitative traits examples
* coat color
* homed or polled
* certain blood characteristics (blood types, presence or absence of particular enzymes)
47
Quantitative traits examples
* growth rate
* live weight
* body measurements and maturity
* milk yield
* milk composition
48
it is possible to establish the fraction of total variation in the population that is caused by the additive effects of the genes. this fraction is known as ?
heritability
49
heritability
show that variations observed in the population of the traits is determined by genetics
1.00
50
heritability
variations observed in the population of the traits is entirely due to environment
0.00
51
heritability
variation is equally due to genetic and environment
0.50
52
are defined as several types mating to combine desirable qualititative and quantitative characteristics through mating sysytems w/c are planned or non-random
breeding systems
53
breeding systems (3)
1. random mating (or unplanned)
2. Inbreeding
3. crossbreeding
54
types of inbreeding (3)
1. close breeding
2. line breeding
3. strain breeding
55
types of cross breeding (2)
1. systematic crossbreeding
| 2. upgrading
56
this means each possible mating in a population has the same probability or occurrence
1. random mating (or unplanned)
57
mating of closely related individuals w/in a breed
2. Inbreeding
58
effects of Inbreeding (4)
1. marked decrease in fertility
2. reduces vigor
3. decrease in growth rate of offspring
4. reduces viability of the offspring
59
mating of close relatives (ex. father-daughter, son-mother, brother, sister
close breeding
60
breeding of not so close relatives (ex. cousins)
this is a form mild inbreeding designed to concentrate the genes of a certain ancestor of the genetic constitution of the progeny
line breeding
61
a very mild form of inbreeding w/c leads to increase homozygousity w/in the strain in the long term
strain breeding
62
meeting of individuals from two or more established purebreds
cross breeding
63
purpose/ benefits of cross breeding (2)
1. to increase heterozygousity
| 2. to take advantage of hybrid vigor or heterosis
64
the average quality of the 1st generation exceeding the average of the 2 parental breeds
hybrid vigor
65
is displayed mainly in the fitness traits, fertility and viability
heterosis
66
type of cross breeding w/c 2 or more breeds are involved in a breeding program lasting several yrs. this way, a crossbred w/c may eventually stabilized into a breed, (ex. Brangus (brahman x Angus); Charbray (Charolsis x brahman)
systematic breeding
67
type of crossbreeding w/c is the mating of purebred sires to nondescript or native female and their offspring generation after generation
Upgrading
68
Reproduction phenomenon
sexual maturity (bulls/heifer)
6-8 mos.
69
estrus cycle
18 -24 days (Ave. 21 days)
70
estrus duration
Exotic/ european breeds -
indigenous/ zebu breeds -
Exotic/ european breeds - 14- 18 hrs.
| indigenous/ zebu breeds - 10-12 hrs
71
ovulation
10-14 hrs after end of estrus
72
parturition
Ave. 283 days
73
Bull Ejaculate
2- 12ml of 500 or more sperm cells/ml
*Sperm cells survive the oviduct up to a maximum of 48 hrs.
74
signs of Estrus
1. mount others
2. reddening and swelling of vulva
3. mucous discharge
4. isolates herself
5. seem sickly and has no appetite
6. frequent urination, restlessness and sometime bellowing or mooing
7. standing still when mounted (the only reliable or true sign of estrus; estrus is defined as the period of sexual receptivity of the female to the male
75
breeding methods
1. natural method
| 2. Artificial Insemination
76
2 types of natural method
1. hand mating
| 2. pasture mating
77
conventional use of bull to impregnate a heifer or cow
1. natural method
78
hand mating
bull in good condition can serve 3-4x a week or one service every other day
I. 18 mos. old -
Ii. 2 yrs old -
Iii. 3yrs old -
I. 18 mos. old - 1:12-15
Ii. 2 yrs old - 1:20-25
Iii. 3yrs old - 1:40-50
79
pasture mating (2-3 mos. old)
I. 2-3 yrs. old bull -
Ii. 9 yrs old bull -
I. 2-3 yrs. old bull - 10-15 cows
| Ii. 9 yrs old bull - 20-25 cows
80
process including fertilization in female w/o the benefit of sexual contact between male and female animals
artificial insemination
81
AI guideline:
"Females observed in estrus in the morning, are inseminated late afternoon of the same day. those observed in the afternoon, are inseminated not later than noon time the next day."
82
some indicators of good breeding or Reproductive management (5)
a. conception rate (pregnancy)
b. % (90 or 120 day) non returns
c. calving rate
d. calving interval
e. 1st heat after parturition
83
% of breeding females that conceived versus the total exposed females
a. conception rate (pregnancy)
cows pregnant at end of breeding season
CR = _________________________________ x 100
cows exposed during breeding season
84
% of breeding females confined pregnant at 90 or 120 days, by pregnancy diagnosis, versus the total exposed females. this is similar to conception rate.
b. % (90 or 120 day) non returns
85
% of breeding females that give birth versus the total exposed females
c. calving rate
86
the average length of time (in days) between successive calving
* can be calculated for each cow or the entire herd
* one year is ideal. 18 mos. is common
d. calving interval
87
the uccurrence of estrus after giving birth to a young. 1st heat is related to calving interval
e. 1st heat after parturition
88
common feeds for ruminants (4)
1. forages
2. by-products forages
3. concentrate
4. use of urea in ruminant ration
89
is the natural cheapest feeds for ruminants and includes not only grasses but also legumes
1. forages
90
most of these are highly fibrous (rice, straw, corn cobs, sugar cane tops), low in CP and TDN and have poor digestibility
2. by-products forages
91
unlike in developed countries, little amount of grain is fed ruminants locally. copra meal, rice bran, wheat pollard are commonly used by-product concentrates, contain from 20% as in case of molasses to 21% in copra meal
3. concentrate
92
has a long used as partial protein source ruminants in other countries
4. use of urea in ruminant ration
93
the ffg. giudelines are recommended for safe use of urea:
add fertilizer grade urea at not more than:
a. 1% of the ration (dry matter basis)
b. 2.3% of the concentrate mixture, (air-dry basis)
c. 25.30% of the total dietary protein
94
ensures the appropriate nutrition of various age groups of the herd;
prevent premature breeding w/c seriously affect the growth of young bulls and heifers and prevent the high rate of abortion resulting from butting and fighting of animals
herd division
95
animals may be divided into the ffg. herds:
1. pregnant herd
2. breeding herd
3. heifer herd
4. steers, feeders or fattening herd
5. bull herd
96
composed of pregnant females. cows are grouped w/ the breeding herd during the breeding season
1. pregnant herd
97
consists of dry cows and heifers ready for breeding. after the breeding season, pregnant animals are transferred to the pregnant herd.
2. breeding herd
98
composed of heifers not yet ready for breeding. heifer calves are included in this herd after weaning
3. heifer herd
99
consists of growing cattle and those to be fattened for the market
4. steers, feeders or fattening herd
100
consists of mature males kept mainly for servicing the breeder cows.
5. bull herd
101
signs of pregnancy
1. cessation of estrus or heat
2. enlargement of the abdomen and udder
3. palpation 60-90 days after breeding (more reliable pregnancy test)
102
is the manual examination of the reproductive tract by way of the rectum and colon to verify pregnancy in cattle
palpation
103
should suckle colostrum milk from their mother w/in 3 hrs after calving
calves
104
are usually maintaned at the pasture w/ very little attention, they are given salt and mineral supplement
grower
105
require a shorter period to reach slaughter weight. they are generally bigger, mature, or nearing maturity.
however, one and a half - 2yr old animals weighing 200-300 kg are preferred.
fatteners
*they maybe fattened either in feedlot, on pasture or both areas
106
this practice is necessary for management purposes and to denote ownership
cattle identification
107
is the most common method of identifying cattle. the owner brand is placed on the animals left foreleg
branding w/ hot iron
108
other effective methods of identifying cattle
putting ear legs or ear notches
109
advantage of dehorning
1. they occupy less space in transit or shipment
| 2. they are more uniform in appearance
110
both effective ways of surgically removing testicles (castrating)
*slit and cap methods
111
bloodless castration
can be done w/ burdizzo pinchers or emasculators
112
tends to decrease the rate of live weight gain by 15% - 20%
castration
113
breeding stock w/ poor performance that should be culled for slaughter:
1. cow that calves every one and a half to 2 yrs
2. produces little amount of milk and raises small calf despite of good feeding and management.
3. small, weak, and unhealthy animals w/c are susceptible to diseases and may become the source of infection of the herd if not removed on time
4. heifers that do not come in heat in spite of proper age, good size, healthy condition, vigor and strength.
5. heifers that fail to meet the standard set for breeding herd
6. bull and cows w/c have undesirable heriditary defects such as inverted teats, hernia, dwarfism, bull dog, cryptorchidism, and the like
114
failure of one or both teats in descend normally
cryptorchidism
115
