Title : Additional Details of the Life History, Morphology and Pathogenicity of EIMERIA NECATRIX TYZZER Material Type: printed text Authors: Bhurtel, Rama, Author Publication Date: 1982 Languages : English (eng) Abstract: Eimeria necatrix of the chicken is redescribed. The
isolate used was obtained from Sterwin laboratories, Inc.,
Opelika, Alabama. This species is primarily a parasite of
the small intestine and cecal pouches, but the middle portion
of the small intestine is involved most. Durinq the course
of severe infection the mid inteztine was swollen, the wall
was dull, reddish in color and was thickened to about l-4
times normal size depending on the degree of infection.
Petechiae were present throughout the small intestine, giving
it a spotted appearance. Intestinal contents varied in
character according to the degree of infection, from clear,
gelatinous, to yellowish clots, which w~re intermingled with
blood clots. The first siqn of infection was evident at the
end of the fourth day postinoculation. On the fifth day siqns were more prominent and birds passed bloody mucoid feces.With severe infections fresh smears of the bldody feces on
7 and 8 days postinoculation contained many blood cells,
excessive mucus, s1uffed pieces of small intestine, a few
schizonts, gametocytes and oocysts. The infection caused
mortality, morbidity, growth depression, poor feed efficiency
and depigmentation. Sudden death was a striking feature of
E. necatrix infection.
Severe infection (300,000 oocysts/layer) caused a sharp or significant
drop in egg production, shell weight and poor egg
shell quality, but not egq weight. The first evidence of a
drop in egg production was on the eighth day postinoculation.
With severe infection (300,000 oocysts/hen), hens ceased to
lay eqqs during the second week after inoculation. Hens
commenced to molt by the eighth day but began to come back
into production by the end of the third week.Link for e-copy: http://elibrary.narc.gov.np/?r=1626 Additional Details of the Life History, Morphology and Pathogenicity of EIMERIA NECATRIX TYZZER [printed text] / Bhurtel, Rama, Author . - 1982.

Title : Effect of pullorum disease on chicks mortality a case study Material Type: printed text Authors: Bhurtel, Rama Publisher: Kathmandu : Nepal Animal Science Association (NASA) Publication Date: 1997 Pagination: 44-48 .p Keywords: Animal production; Pasture; Feed crops; nutrition; breeding; Fisheries; Livestock Abstract: This study was undertaken to find out the duration and percentage mortality of the chicks produced by infected flocks carrying Salmonella Pullorum organism. Pullorum is a highly contagious disease among the young chicks and is also an egg born disease. Rapid blood tests were done 4 times for breeder hens of government farm of Khumaltar, which was handed over to the Avian Research Program. Hens which showed positive reaction to the test were discarded and eggs of the rest of the hens were collected and hatched. Two hatches of three thousand eight hundred and fifty nine chicks were kept in Khumaltar. Replacement stocks kept on 1996-4-6 (2053/12/24) having 1778 chicks had 77% percent mortality and second replacement stock kept on 1996-6-14(2054/3/1) having 2081 chicks had 50% mortality. Death losses started from the first day of hatching but increased from the third day onward. Maximum mortality was within first two weeks. Infected chicks huddled together, and seemed chilled and had ruffled feathers. Some of the chicks had pasted vent, inflamed hock joints and difficulty in breathing. Unabsorbed yolk was found in some of the dead chicks. Salmonella Pullorum was identified by the Animal Health Research Program of Tripureswor through the cultures taken from the organs as liver, ovary heart and spleen of the dead chicks.

Title : Effect on production performance of layer type chickens on pellet vs mash feed of same feed composition Material Type: printed text Authors: Osti, N.P. ; Dhaubhadel T, Author ; Bhurtel, Rama, Author ; Koirala P.K, Author Publisher: Kathmandu : Nepal Animal Science Association (NASA) Publication Date: 1997 Pagination: 103-107 .p Keywords: Animal production; Pasture; Feed crops; nutrition; breeding; Fisheries; Livestock Abstract: The effect on production performance of layer type chickens on pellet vs. mash feed of same feed composition was observed. The New Hampshire chickens were involved in the experiment for the period of 12 months. Five months old pullets consisting of 209 pullets and 109 cockerels were fed pellet feed and housed in hall 1 and same number of pullets and cockerels fed on commercial mixture (mash feed) and housed in hall 2.The differences was not significant between performances of two feeding systems, in the percentage of laying (33 and 29 eggs/days/1OOhens), in the feed intake of hens (81.18 and 83.69 g/d/h and in the feed efficiency. The minimum feed required per dozen egg production was found in pellet feeding group (1.8 kg/dozen eggs), where as mash feeding group consumed 2.8 kg feed for same number of eggs.
