background & aim: medicinal plants is very potential to be used as a supplementary feed as well as feed additive in broilers.this experiment was conducted to investigate the effects of milk thistle (mt) and thyme seeds (ts) on the performance in broilers. experimental: in this study, 160 one-day-old (ross 308) male broiler chicks were divided randomly into four major groups with 4 replicate...

this experiment was conducted to investigate the effects of lactobacillus acidophilus on performance, carcass characteristics, blood parameters, and intestinal microflora of broiler chicks. the dietary treatments were: basal diet as control 1; basal diet plus 1g. kg-1 of a commercial probiotic bioplus2; basal diet plus 10 and 20 g kg-1 fermented milk that contained 2×108 cfu g-1 lactobacillus a...

Growing chicks maintained on a diet consisting of milk powder, casein, starch, yeast, cod liver oil, salts and filter paper develop ataxia, tremors, retraction or twisting of the head, clonic spasms of the legs, and stupor. These symptoms may appear suddenly, usually between the 18th and 25th day, and may end in death. If recovery takes place, the chicks may go on to normal development. Definit...

An organic compound containing 5.86 per cent phosphorus and 11.9 per cent nitrogen was isolated (1) from the tryptic digest of bovine milk casein. Further study (2) suggested that, since serine was the only hydroxyamino acid in the compound, it appeared likely that phosphoric acid was bound to the hydroxy group of this amino acid. A serine phosphoric acid was prepared directly from casein (3) a...

The ability of mothers to transfer antibodies (Abs) to their young and the temporal persistence of maternal Abs in offspring constitute important life-history traits that can impact the evolution of host-parasite interactions. Here, we examined the effects of food availability and parental immunization on the transfer and persistence of maternal antibodies in nestling pigeons (Columba livia). T...

The r61e of choline in the nutrition of the young rat has been studied extensively (14). Sure (5) has also shown the need of choline for lactation in mature animals. Its relation to the nutrition of the chick has not been studied, although Abbott and DeMasters (6) concluded that the addition of choline to a skim milk powder-polished rice ration increased egg production and decreased mortality i...

Shortly after we had demonstrated in this laboratory (1) that nutritional anemia could be induced in rabbits by a diet of cow’s whole milk, and that this anemia could not be corrected by inorganic iron unless it was supplemented with a natural food material, or a preparation from this material, we attempted to use chicks as experimental animals for anemia studies. A survey of the literature at ...
