Influence of Water-Treatment on Nutritional Value of Barley.∗:

Summary The results obtained in 2 independent experiments demonstrated that a simple water treatment of pearled barley markedly improved the nutritional value of this cereal grain. Treated barley was equal to corn for chick growth. The diet containing treated pearled barley gave significantly better (P<.01) feed efficiency than the diet containing corn or untreated pearled barley.

Effect of Antibiotics on Intestinal Microflora and on Growth of Turkeys and Pigs.

Conclusions In view of the inhibitory effect of penicillin and terramycin on C. perjringens in the intestinal tract of turkeys and of terramycin in pigs, it appears possible that these antibiotics promote growth by preventing enterotoxemia. This possibility is supported by data gathered by Merchant( 16 ) which show that enterotoxemia in sheep is caused by C. perjringens.

Effect of Ethanolamine and Betaine on Perosis in Chicks.

Summary Summary. The occurrence of perosis in chicks was markedly reduced by supplementing the basal diet with betaine hydrochloride. Ethanolamine was slightly effective in one experiment in preventing perosis but not in the other. Supplementing the diet with both ethanolamine and betaine was somewhat more effective in reducing perosis than either one alone. Under the experimental conditions betaine also promoted growth and reduced mortality.

Effects of Vitamin E, N,N1-Diphenyl-Para-Phenylene Diamine, and Fish Liver Oil on Reproduction in Turkeys.

Summary Fish liver oil added to the diet greatly accentuated a deficiency of vit. E in turkey breeders. A reduction in fertility due to a vit. E deficiency was suggested. Both alpha tocopheryl acetate and DPPD counteracted the deleterious effect of fish oil on hatchability. With fish oil in the diet, tocopherol levels of the yolks of eggs were not appreciably increased by either vit. E or DPPD even though hatchability was near maximum.

Effect of vitamin B12 deficiency on chick plasma proteins

Abstract The effect of vitamin B12 deficiency upon the levels of plasma protein and its fractions in chicks was studied. At both 4 and 8 weeks, plasma protein of vitamin B12-supplemented chicks, both male and female, was significantly higher than that of deficient chicks. Plasma protein fractions were determined after treatment of plasma with differing concentrations of sodium sulfate. For both males and females, there were significant differences between B12-deficient and supplemented chicks with regard to total plasma protein and albumin. In the females, B12-supplemented and deficient chicks also differed with regard to total globulin and pseudoglobulin II; in the cockerels, euglobulin was higher in the B12-supplemented birds. Prothrombin times were higher and fibrinogen levels were lower in the vitamin B12-deficient chicks than in the supplemented chicks. It seems possible that B12 functions in protein metabolism by stimulating formation of ribonucleoprotein and plasma proteins.

The effect of terramycin on the growth of rabbits

Abstract The results obtained by feeding graded levels of terramycin to weanling rabbits failed to show any effect of the antibiotic on body weight gains during a 6-week experimental period.

The effect of vitamin B12 deficiency on erythrocyte counts and hemoglobin levels of chick embryo blood.

Abstract Experiments were conducted to investigate the effect of vitamin B 12 deficiency upon hemoglobin levels and erythrocyte counts in White Leghorn chicks and embryos. Hemoglobin and red cell counts on vitamin B 12 -supplemented embryo blood were significantly higher than on blood of B 12 -deficient embryos from the 18th to 21st day of incubation. Vitamin B 12 injected into the egg was as effective in raising embryo hemoglobin levels and red cell counts as B 12 added to the diet of the laying hens. Terramycin added to a B 12 -deficient diet for hens did not improve hemoglobin levels or erythrocyte counts in hatched chicks in spite of the fact that hatchability was markedly improved. The relation between B 12 , terramycin, and hatchability is discussed.

Black Pigmentation in Feathers of Buff Orpington Chicks Caused by Vitamin D Deficiency.

Summary In an experiment with Buff Orpington chicks. a breed normally having no black pigment in the feathers, it was found that a deficiency of vitamin U caused a widespread deposition of black pigment in the feathers. This abnormal blackening was prevented by supplenienting the diet with vitamin D. The feeding of thyroactive ioclinated casein failed to increase the deposition of black pigment in chicks fed either a vitamin D deficient or vitamin D supplemental diet.

The effect of diethylstilbestrol on mortality caused by visceral gout in chicks

Abstract It was found that treatment of chicks with diethylstilbestrol greatly reduced mortality from visceral gout. This effect was particularly pronounced with male chicks.

Effect of terramycin and vitamin B12 on hatchability.

Summary An experiment was conducted with White Leghorn pullets to determine the effect of feeding terramycin alone and in combination with vit. B12 on egg production and hatchability. The results obtained indicate that terramycin had little or no effect on egg roduction and gain in weight. In the absence of vit. B12, hatchability of fertile eggs was definitely improved by feeding terramycin. There was an indication that terramvcin fed in combination with vit. B12 further improved hatchability.
