Could anybody suggest me a medicine for prolapse problem in deep litter of bovans breed which are in 23 week and the weigtht is 1.500kg of bovans breed kindly suggest me the lighting program. I am incurring daily mortality of 5 birds per day. Please help me.
To solve prolapse in your layers you have to start early at the rearing period by enhancing your layer chicks to grow and getting the optimal body conformation with large abdominal cavity and good muscles distribution over body bones before 6 weeks of age and your target body weight.
Must be over or on standard before 12 weeks age this may come from good feed components and texture, feed space, light duration birds density good debeaking if it's done.
Don't over stimulate your layer by light to push them to lay early and use warm light source in the production period and if you want to increase light duration or intensity do it gradually also don't change time of feeding or lighting, or eggs collection.
calcium % = 3.6 to 3.9 may reach 4.0 depends on feed intake per bird per day each layer need around 4000 mg calcium per day to produce good shelled eggs
p available from 0.38 to 0.42 % in the complete feed and this decrease by age may reach 0.35 % for more than 70 weeks age layers
yes. unfortunately prolapse cause death for layer in most cases
Kudos to my all the contributors!!!
The issue of infectious bronchitis can also cause prolapse due to shrinkage/occlussion of the ovipositor and abdominal layer(egg in the abdominal cavity) this makes bird strain to lay which is abortive leading to
...protrusion of the uterus
...shrink and pale comb
It is important to have efficient vaccination
Verify the density or otherwise actual floor space is provided or not
Check salt and fiber content of the diet
Methionine level should checked and rectified
Check the calcium and phosphorus level in the diet
We are practicing as follows
1 Maintain ca:p ratio 8.11
2 Maintain protein 18%
3.space 1.66 square feet
4. Light 20 lux
5 Light is calculated as(area in sq ft/ 10.765*300)/300 This is for 9 watt led light or 25 watt cfl or 60 watt fillament bulb
Maintain methionine 0.42%
7 light hour day lenghth plus required hour=16:30
Review lighting intensity 5-10 lux avoid picking feed may include zeralenone toxins -low choline level or high energy problem in uniformity of body weight leading to egg impaction vitamin B+K3+CHOLINE liver enhancer &detoxifier product
A bodyweight of 1.50 kg at 23 weeks indicates that your hens are too light and small, causing the prolapse to occur as soon as laying commences. This is a carry over problem of underweight pullets. You should upgrade the specs of your Pullet Starter (0 - 5 weeks old) and Pullet Grower (5 - 10 weeks old) feeds to help your pullets achieve the standard bodyweight curve. Once your pullet bodyweight is on the standard and the uniformity is good at 10 weeks old, the prolapse problem will disappear.
There several reasons which contributes to the prolapse in commercial layers. Nutrition is one among the major factors which leads to the prolapse such as high energy and protein ratio at early stage of laying might lead to the production of large eggs before prior complete skeletal development eventually uterine prolapse; improper calcium/phosphorous ratio may hinder absorption of calcium whilst impair skeletal development and limit passage of eggs and eventually prolapse; Deficiency calcium, phosphorus, protein particularly with essential amino acids such as lysine and methionine, vitamin in B complex, vitamin D, Vitamin E the diet may lead to prolapse. Other factors are associated with management such supply of light for more than 16 hours will stimulate birds to early laying before complete skeletal and muscular development lead to the prolapse.
In addition to the above points mentioned prolapse in laying birds is related to several factors: breed, nutrition, housing system, management practices, lighting regime, photostimulation, effective weight management and microclimate, among the factors
Hi to all: I agree with Mr Robert that basically prolapse is because of management topics but to analyse the causes and to solve it must look at which age it occurs? 1- Just after start of production 2- in the middle age whiteout observe it before that time 3- in aged flocks for example more than 60 weeks age?
In start of production it is the very bad kind and is due to bed management in rearing, specially in first 6 weeks of age and not uniform flocks before start of production. In middle age more often is due to sudden increase in egg size or calcium and phosphor deficiency or incorrect ratio. And in age flocks it is due to loss of body weight and natural moult of some percent of flock.
Birds below target weight (under weight) specially from week 8 to 16 are more susceptible to prolapse. Also these birds will not peak and have higher non specific mortality after week 55.
All under weight birds are segregated at rearing and provided enough feeder space and feed to recover body weights.
Water restriction during rearing for about 1-1.5 hours in the morning helps feed to stay in intestine for longer period reducing reverse peristalsis. This will reduce the prolapse incidence. (Care is excersised to avoid heatstress. Water restriction followed till egg production)
One herbal supplement available to reduce the incidence and anyone interested do let me know.
