Possible involvment of carbohydrate and lipid metabolism in the incidence of sudden death syndrome in broiler chickensAttamangkune, Seksom 29 October 1992 (has links)
Seven experiments were carried out to investigate the
involvement of carbohydrate and lipid metabolism on the
incidence of Sudden Death Syndrome (SDS) in broiler
chickens.
Hepatic arachidonate level decreased after 1 h postmortem.
The decreased level of hepatic arachidonate
previously observed in SDS birds was, therefore, associated
with the post-mortem aging.
Broiler chickens fed diets high in glucose monohydrate
(cerelose) were more susceptible to SDS mortality than
broilers fed diets high in corn starch or corn-soy. Feeding
broilers a high cerelose diet increased the levels of plasma
calcium, total protein, triacylglycerol, and uric acid
compared to broilers fed corn starch diet. Broilers fed
cerelose diet also showed the higher incidence of leg
abnormality than broilers fed corn starch or corn-soy diets.
Daily intraperitoneal injection with 0.25 ml of L(+)
lactic acid solution (100 mg lactic acid/ml) to broilers
over a 7-d period failed to reproduce the SDS incidence,
whereas intravenous injection of 40% lactic acid solution
(200 mg lactic acid/kg body weight) resulted in 100%
incidence of SDS-type mortality. No SDS-type mortality was
observed with the intravenous injection of 40% sodium
lactate solution (200 mg sodium lactate/kg body weight).
Disturbance of physiological acid-base balance might be a
factor in the SDS-type mortality.
Suboptimal thiamin level in broilers fed cerelose diets
was observed. Thiamin supplementation to cerelose diet
improved the thiamin status of the broilers. Mortality due
to SDS was decreased when thiamin hydrochloride was
supplemented to cerelose diet at the level of 0.6 and 2.8 mg
thiamin hydrochloride/kg diet, respectively. Thiamin
supplementation, however, did not change the liver pyruvate
dehydrogenase activity and the proportion of pyruvate
dehydrogenase in the active form.
Disturbance of acid-base balance was postulated to be
associated with the incidence of SDS. Other genetic,
nutritional, and environmental factors are likely to modify
the incidence by affecting the acid-base status of the
chicken. / Graduation date: 1993

Nutritional implications in broilers fed single or a combination of feed ingredients during feed shortages in the Republic of YemenModhish, Abdulmalek M. 07 February 1991 (has links)
Most of the feed required for poultry production in
the Republic of Yemen is imported from Europe. Sometimes,
feed shipments arrive later due to lack of hard currencies
to pay for the feed or to pay the freight charges. Yemeni
broiler producers in such cases feed their birds a single
feed ingredient or a mixture of ingredients until feed
arrives.
Five experiments were conducted to simulate feed
shortage situations. As a single ingredient, barley is the
grain of choice in case of feed shortages. When broilers
were switched to corn-soy after the single ingredient
diets, the compensatory growth was correlated with the
severity of reduced growth.
Feeding diets with a mixture of faba beans + sorghum
grain with or without 7% herring meal for 21 and 49 days,
respectively, reduced significantly (P<.05) mean body
weight, total feed consumed, feed efficiency and apparent
protein efficiency ratio.
Feeding wheat bran at 10-15% with adjustment for protein
and energy from day-old to 49 days of age resulted in
significantly (P<.05) improved mean body weights compared to
the control broilers. Increasing wheat bran levels further
gradually reduced body weight and feed consumption.
Abdominal fat increased significantly (P<.05) when wheat
bran inclusion exceeded 20 percent.
Cellulase supplementation did not show any significant
interaction with wheat bran in all the measured parameters.
Supplementing protease to wheat bran diets significantly
(P<.05) reduced mean body weight, feed consumption and the
feed conversion in broilers. These dramatic effects were
proportionally ameliorated by increasing the levels of wheat
bran. / Graduation date: 1991
