- PREFERENCES FOR FRESH AND FRESH-CHILLED PORK
- REFERENCES FOR PARTS
- EMERGENCE OF SMALL ENTERPRISES TYPE OF SWINE PRODUCTION SYSTEM
What are the strengths of swine production?
a. Relatively large, stable & continuously increasing pig population tat is well distributed throughout the country
b. Large & continuously increasing domestic market for pork
c. High utilization of pork, relative to other animal products
d. Well organized private industry players
e. Easy access to good genetics & state-of-the-art technologies on swine production, feed milling & other related activities from both local & foreign sources
f. Technically equipped entrepreneurs, farm managers & practitioners
Weaknesses of Swine Production
a. Generally low purchasing power of pork consumers
b. High cost of feeds & other production inputs
c. Heavy independence on imported feed ingredients
d. Inadequate national program for disease prevention and control
e. Inefficient & inadequate technical & market information services
f. High overhead costs both in swine production & feed milling
g. Presence of FMD in some major swine-producing regions of the country
This is the period between weaning & the next service. after weaning, a sow is expected to come into heat within 3 to 7 days.
dry period
gestation period of sow
114 days or 3 months 3 weeks and 3 days
normal lactation period is between?
28 to 42 days
rearing period of weaners days?
30-40 days
The rearing period take another 30 – 40 days. At the end, they will be ready for sale, fattening or rearing as replacement breeders. By then their weight will be?
15 – 20 kgs
growing and finishing of fatteners takes how many months
3 - 5 months
What are the threats in swine production?
a. Flooding/dumping of cheap pork & other meat products from other countries
b. Increasing control of trader & butchers on pricing of live slaughter hogs
c. Irrational implementation of rules & policies on environment protection
d. Industrialization & urbanization of current swine producing areas
What are the opportunities in swine production?
a. Growing domestic market, increasing demand to meet increasing per capita consumption of a continuously growing human population
b. Export of live hogs &pork carcasses to other ASEAN countries
c. Availability of certified breeder pigs will be assured by the operationalization of the Swine Breeder farm Accreditation Program of the DA
d. Continuously improving swine productivity & production efficiency
e. Improved feed efficiency & dressing percentage by increasing slaughter weights
Rearing period of replacement stocks no. of days/months
150 - 180 days (5 - 6 months)
produce & nourish large litters of healthy pigs
prolificness
active; good disposition; easy to handle
temperament
high in lean cuts & low in fat cuts
carcass quality
some breeds perform better when crossbred
nicking ability
What are the factors in selecting a breeding herd?
- Availability of good stocks
- prolificness
- growth ability
- temperament
- carcass quality
- efficient use of feeds
- nicking ability
- market demands
- disease resistance
- availability of feeds
- personal likes and dislikes
group that has specific traits or characteristics in common
breed
performance of a pig is influenced by its ______ which includes nutrition & feeding, housing, health care etc. comprising 70% of the totality of the animal
ENVIRONMENT
comprising 30% thus it is important to look into the bloodline of the animal
genetic potential
Breeding of closely related animals
inbreeding
done to purity the blood line of the animals since the similarity of the animals within the group is increased. Strong & weak points of the animal will be exposed under this system
inbreeding
not recommendable due to its negative effect on the production performance of the animal. It usually decreases vigor because it brings together the recessive genes with undesirable effects in the resulting crossbreed
continuous inbreeding
Effects of inbreeding, if not properly done:
- Reduction in the strength & vigor of piglets
- Decrease in the number of pigs born & weaned
- Decrease in the weight of piglets at birth & weaning
- Sterility & abortions
- Retardation of physiologic maturity
- Occurrence of abnormalities (hernia, cryptorchidism)
A system of breeding wherein animals of the same breed are mated to each other.
Purebreeding
Breeding of 2 animals from different breeds
crossbreeding
done to maintain the production supply of the breed & to acquire the best available genetic material at reasonable prices
purebreeding
2 reasons crossbreeding system is recommended for production of market hogs
a. To obtain hybrid vigor or heterosis (the superiority exhibit by the crossbreed individuals over the average of the parental breeds);
b. To bring together the desirable characteristics of the parental breeds
Advantages of crossbreed over purebred animals
- Superior in terms of litter & weight at birth & at weaning
- Sows are better mothers
- Fast growing
Advantages of crossbreeding
- Increased vigor & growth rate of litters
- Large litters
- Increased production efficiency to about 5 – 10%
- Increased disease resistance
LARGE WHITE x LANDRACE or
PIETRAIN x DUROC
Two-way cross mating with the use of 2 different breeds
LARGE WHITE x LANDRACE (1st cross)
DUROX x LARGE WHITE/LANDRACE (2nd cross)
DUROX/LARGE WHITE/LANDRACE (progeny)
Three-way cross mating with the use of three breeds
A system of breeding wherein an inferior breed is improved by continued crossing.
upgrading
Commonly used among native breeds crossed with exotic breeds of swine to improve the common stock.
In this procedure, selected female pigs are bred to purebred boars of any preferred breed. The female progenies are bred to boars of the same breed. The procedure is repeated until the resulting offspring’s approach the characteristics of the purebred.
upgrading
It can lower the quality of the whole herd. The most common are hernias, atresia ani and cryptorchidism.
abnormalities
few of the diseases commonly associated with abortion and usually transmitted by an infected boar
leptospirosis and brucellosis
a vital source of nourishment for the piglets. It is highly susceptible to infection especially during lactation because of the presence of milk which is a very good medium for multiplication of infectious microorganism
udder section
A sow is must profitable if she produces more than 2 litters a year or else she is considered as?
profit eater
Some sows have cannibalistic tendency during and after farrowing especially the first-farrowed sow
poor maternal instincts
Pointers in Culling
- Reproductive failures
- Poor maternal instincts
- Feet and leg problem
- Poor milkers
- Poor litter size
- Long dry period
- Damaged udder section
- Diseases
- Abnormalities
the beginning of the reproductive capability or sexual maturity of the animal
puberty
Requirements for judging and selecting sows
- Good production of the sow
- long life
- good ADG for the offspring
- good FCR of the offspring
- good carcass quality of the offspring
