VIII. The Fattening Period Flashcards
period starting from the transfer to the fattening unit until they reach the slaughter weight of about 85 kg
Fattening period
Floor space required of a pig with 20 – 45 kg bw
0.37 sq m
Floor space required of a pig with 46 – 102 kg bw
0.84 sq m
Must be done to keep fighting and stress to a mininum
Grouping the pigs by size
Behavioral vices
a. tail biting
b. ear biting
c. belly rubbing
d. fighting
Pointers to reduce stress of weaners during transport
a. add vitamins & electrolyte to the drinking water 2 – 3 days before transport
b. transport weaners during the coldest part of the day
c. piglets should not be handled roughly & allowed to walk by themselves to the transport vehicle
d. if the vehicle is long, separations are necessary to prevent crushing or overcrowding on one end
e. animals should not be fully feed before transport & drinking water should be given during long trips
Pointers to reduce stress for newly arrived weaners
- clean & disinfectant pens prior to arrival
- provided a warm environment between 21 & 24 C for the first few days after arrival
- provide enough space, group according to size & separate weak piglets
- feed & watering devices should be easily accessible
- restrict feeding after arrival to avoid upset stomach
- gradual shifting in a week period should be observed
temperature for the first days of arrival of weaners
21 to 24 C
For newly arrived weaners, in every kg of feed they will consume how many L of water
3 - 6 L
room temperature in a fattening unit should be approximately?
18 to 20 C
are key to a well- ventilated swine unit
air inlets (ventilation)
Spray cooling using a fairly coarse water sprinkler spray system at ______ per pig per hour is advised when temperature exceed _____
0.45 liters; 27 C
During transport from farm to abattoir, pigs can lose weight by _______ of the original weight due to defecation & urination
2 – 10 %
Feed represents the highest cost in producing pigs which accounts for_______ % of the total production cost
70 – 80%
Starter
15 - 20 kg
Grower
30 to 35 kg
Finisher
60 to 90 kg
3 basic feeding systems for fatteners
- Ad libitum
- Restricted feeding
- COMBINATION OF RESTRICTED FEEDING & ADLIBITUM
Choice of feeding system can be determined considering the following factors
- Genetics potential of the breed
- Quality of the feed
- Environment, housing & climatic condition
- Health status of the animal
- Availability of quality feeds & raw materials
- Influence of carcass quality on selling price
Wet feeding
a. reduce feed wastage
b. increase digestibility
c. higher feed intake
d. laborious
e. spoilage
f. attract more flies
Dry feeding
a. higher amount of feed wastage
b. lower digestibility
c. lower feed intake
d. less labor
e. less spoilage
f. needs separate feeding trough and waterer
If the genetic potential of the pig is good (fast grower), the pig can be fed with starter feed till they weight ______ kg liveweight
45 – 60
most crucial factor in the occurrence of disease among fatteners
environment changes
Diseases that affect the Digestive System
- Salmonellosis
- Swine dysentery
Abdominal breathing
pneumonia and pleuritis
rapid breathing
associated with pneumonia, cardiac insufficiency, anemia, pneumonia and pain
Grayish/crushed color of skin indicates
parasites, nutritional balance
Bluish color of the skin indicates
circulatory disturbance
white/pale color of the skin indicates
anemia
red color of the skin indicates
hyperemia, fever
avoided by pigs with heart disease; while it is favored by animals suffering from exhaustion for overeating
Lateral posture
favored by cold animals with 4 legs tucked under their body; also associated with respiratory problem if accompanied by mouth breathing
sternal recumbency
associated with respiratory disease, cardiac insufficiency, pleuritis or anemia
dog sitting
Extended head posture may indicate
animal has a respiratory problem
a nervous symptom; probably caused by an infected ear; leptospirosis
circling movement
FMD is given
2-3 months of age
Pseudorabies given
2-3 m of age
Vaccination of Pneumonia bacteria
2-3 months of age
In highly risk areas, deworming is repeated after how many days
7 days
Infectious Agents Involved in Pneumonia
- Influenza
- Actinobacillus pleuropneumonia
- Enzootic pneumonia
- Atropic rhinitis
Checking Health Condition of fatteners
- Posture
- Rapid breathing
- Abdominal breathing
- Color of the skin
3 important points should be considered for feeding of fatteners
- The lower the weight of the piglets, the higher should be the quality of the starter feed
- If the genetic potential of the pig is good (fast grower), the pig can be feed with starter fed till they weight 45 – 60 kg liveweight
- Changing feeds should be done gradually
