An experiment was performed to examine the effect of protein source and dietary amino acid profile on intestinal levels of C. perfringens in broiler chickens. Broiler chickens (age = 14 d; n = 192) were fed diets containing 400 g kg-1 crude protein with fish meal, meat/bone meal, feather meal, corn gluten meal, soy protein concentrate, pea protein concentrate, or potato protein concentrate as the primary protein source along with a control diet containing 230 g kg-1 crude protein. The birds were orally inoculated daily, with 1 mL (~1.0 × 108 CFU mL-1) of an overnight culture of C. perfringens between 14 and 21 d of age, killed at 28 d of age and C. perfringens numbers in ileum and cecum were enumerated. Birds fed fish meal, meat/bone meal, feather meal and potato protein concentrate had significantly higher intestinal C. perfringens counts than the birds fed corn gluten meal, soy or pea protein concentrates or the control diet (P < 0.05). The glycine content of the diets and ileal contents was significantly, positively correlated with C. perfringens numbers in ileum and cecum. Dietary glycine may be an important factor in the intestinal overgrowth of C. perfringens in broiler chickens. Key words: Clostridium perfringens, broiler chicken, amino acid, glycine, necrotic enteritis

Ottawa 1926.This bulletin presents for the first tilne in Canada a detailed review of those highly nitrogenous feeds — the output for the most part of the packing-house. Much confusion exists in respect to the meaning attached to the names under which they are sold.

The effects of supplementing the protein from wheat in diets for growing pigs with either whale meal, whale solubles, fish meal, meat and bone meal or with combinations of whale meal or whale solubles with fish meal or meat and bone meal, were studied in two experiments. The mercury concentration in the muscle and liver of pigs fed the whale products was also studied. Pigs fed diets containing whale solubles as the only protein concentrate, grew more slowly, required more food per unit of liveweight gain and tended to have less lean in their hams than pigs fed diets containing concentrate protein from whale meal and/or fish meal, whale meal and meat and bone meal, or whale solubles and fish meal. The differences in pig performance between diets containing whale meal or meat and bone meal were not significant. Whale meal and whale solubles contained 10.5 and 2.5 p.p.m. of mercury, respectively, and the concentration of mercury in the diet was correlated to the mercury concentration in the tissues of pigs fed the diet. The muscle and liver of pigs fed with protein from whale meal had higher concentrations of mercury than those of pigs fed diets with equal amounts of protein from whale solubles. All the pigs fed whale products in this experiment had a concentration of mercury in their tissues greater than the health standard for human feedstuffs.

An eight-weeks feeding trial was conducted to study the effects of dietary L-lysine and/or phytase supplementation in corn gluten meal-soybean meal (CGM-SBM) protein blend diets on the growth, apparent digestibility, whole body chemical composition and digestive enzyme activity of Pacific white shrimp Penaeus vannamei (Boone, 1931) juveniles. Five isonitrogenous and isolipidic diets were formulated viz., control diet (T0), with 20% fishmeal was compared against four CGM-SBM based diets, T1 with no supplementation, T2 supplemented with L-lysine, T3 supplemented with phytase and T4 supplemented with L-lysine + phytase. Dietary lysine supplementation had a significant effect (p<0.05) on growth performance and feed conversion ratio (FCR), while supplementation of dietary phytase had no effect on growth performance. Apparent digestibility coefficient (ADC) value for crude protein increased by 2.5 to 3% on supplementation of phytase (500 FTU kg-1 feed) in the diets. The protein digestibility increased by 8 to 11% with the addition of dietary phytase than other treatment groups with no supplementation of phytase. The amylase and lipase enzyme activity of T3 and T4 supplemented with dietary phytase was higher than the groups that were not supplemented with dietary phytase. Higher protease activity was observed in T2 diet supplemented with dietary L-lysine. L-lysine and phytase supplementation in plant based CGM-SBM protein blend diets resulted in better growth performance of P. vannamei.
