Testing of Two Varieties of Lupin Seeds as Substitutes for Soya Extracted Meal in Vegetable Diets Designed for Young Broilers

The main aim of this experiment was to verify the suitability of two Polish varieties of dehulled lupin seed (the low-protein SONET variety and the high-protein JUNO variety) as protein components to replace 50% of soya extract meal in feeding mixtures designed for the feeding of young broilers. The results of this experiment demonstrate that suitable treatment of lupin seed (dehulling) may significantly increase its nutritional value. Dehulling provides a product (core) in which the level of nitrogen-containing substances is by 27% higher than that in the original seed, providing an important protein component to be added in feeding mixtures for chickens. The experiment has also shown that production performance depends on the particular Lupinus variety used. Chickens fed on the JUNO variety seed (Group E1) reached a live weight of 2.332 kg on Day 40, which is comparable with the control group of chickens (2.337 kg; Group C). However, chickens in Group E2 fed on the SONET variety seed had a conclusively lower average weight (2.280 kg) (P Lupinus genus is a major source of the amino acid arginine, which is often deficient in the feeding mixtures

The aim of this study was to determine and evaluate the chemical composition of the seeds of the genus Lupinus and soybeans. The chemical analyses were carried out in frequently grown lupi

DIFFERENCES IN MEAT NUTRITIONAL COMPOSITION OF SIX WILDFOWL VARIETIES

Na temelju analize mišićne mase prsa i bataka šest vrsta pernate divljači (divlji puran / Meleagris gallopavo, biserke / Numida meleagris, jarebice kamenjarke-čukare / Alectoris chucar, japanske prepelice / Coturnix japonica, običnog fazana / Phasianus colchicus i trčke skvržulje / Perdix perdix) može se zaključiti da je njihovo meso vrlo kvalitetno za prehranu ljudi. Zbog visokog sadržaja bjelančevina i niskog sadržaja masti posebno je kvalitetno meso čukare, biserke i običnog fazana. Mišićna masa, kao što proizlazi iz rezultata analiza, predstavlja i značajan izvor mineralnih tvari, posebice kalcija (Ca), fosfora (P) i magnezija (Mg). Rezultati analiza ukazali su na značajnu razliku u nutritivnoj vrijednosti mišićne mase prsa i bataka. Razlika je uzrokovana znatno višim sadržajem bjelančevina, nižim sadržajem masti i većom količinom ukupnih minerala (pepela) u prsnom mišićju u odnosu na mišiće bataka. Kod mišićne mase prsa utvrđen je veći sadržaj Mg, pa i P (osim čukare). Sadržaj Ca međutim, bio je ovisan više o vrsti pernate divljači nego o anatomskom porijeklu mišićne mase.Based on the muscle mass analysis of breast and drumstics of six wildfowl varieties (Wild turkey / Maleagris gallopavo, Guinea fowl / Numida meleagris, Greek partridge- chukar / Alectoris chukar, Japanese quail / Cotumix japonica, Common pheasant / Phasianus colchicus and Grey partridge / Perdix perdix) a conclusion can be made that their meat is very good for human consumption. Due to the high protein and low fat content particularly good is the meat of choker, Greek partridge and Common pheasant. Muscle mass, according to the analysis, is a significant source of minerals, particularly calcium (Ca), phosphorus (P) and magnesium (Mg). Analysis results indicate a significant difference in nutritional value of muscle mass of breast and drumstics.The difference is the result of a much higher protein and lower fat content, as well as a higher amount of total minerals (ash) in the breast muscle as compared to the muscle of drumsticks. In the breast muscle a higher Mg and P (except in chukar) was determined. The Ca amount, however, depended more on the wildfowl variety than on the anatomical origin of muscle mass

BREWERS YEAST IN BROILER FEED MIXTURES AS A SUBSTITUTION FOR FISH MEAL

Istražena je upotreba pivskog kvasca kao bjelančevinastog krmiva u hranidbi muških i ženskih pilića u tovu. Istraživanje je provedeno na 12 tovna hibrida linije Ross 08. Pilići su bili podijeljeni po spolu i po vrsti hrane, odnosno bjelančevinastog dijela hrane, na kontrolne i pokusne skupine. Pokusne skupine su hranjene smjesama koje su kao izvor bjelančevina sadržavale pivski kvasac, a kontrolne skupine hranjene su uobičajenim smjesama koje su sadržavale riblje brašno (ali samo u početnoj smjesi za tov) kao izvor bjelančevine. Tijekom 42 dana pokusa pili_i su hranjeni po volji i držani su u kontroliranim zoohigijenskim uvjetima. Pored razlike u podrijetlu bjelančevina smjese su bile podjednake po sadržaju bjelančevina, energije i ostalih komponenti. Praćeni su prirasti tjelesne mase, utrošak hrane, zdravlje i mortalitet pilića. Rezultati istraživanja su pokazali da nema statistički značajnih razlika (P>0,05) između pokusne i kontrolne skupine istoga spola. Ovakvi rezultati nam govore u prilog zaključku da se bjelančevine životinjskog podrijetla uspješno mogu zamijeniti bjelančevinama pivskog kvasca.The influence of brewers yeast on production results was investigated on 162 Ross 308 broilers Chickens were divided according to sex and according to protein source in feed. Control groups were fed commercial feed mixtures containing fish meal, soybean meal and sunflower meal in starter and soybean meal and sunflower meal in finisher. Experimental groups were fed commercial feed mixtures containing brewers yeast, soybean meal and sunflower meal in starter and finisher as a protein source. Body mass, body mass gain, feed conversion ratio, health status, mortality and carcass characteristics were investigated during 42 days of the experiment. Results showed that there were no significant differences between control and experimental group of the same sex. We concluded that brewers yeast could replace protein of animal origin in feed mixtures for fattening chickens

Effects of cimetidine on broiler fattening and on stress-induced gizzard erosion in chicken

The work describes the effects of cimetidine on stress-induced gizzard erosions (Experiment A) and the influence of the long-term application (42 days) of the same drug on weight gain and feed consumption during broiler fattening (Experiment B). For Experiment A, 60 male, three-day-old chicks were divided into two groups: C (n = 30) - control chicks treated with 0.5 ml saline; CIM (n = 30) - chicks treated with cimetidine in a dose of 5 mg/kg body weight (b. w.) in-tragastrically. All chicks were stressed using a modified water-immersion stress method according to which the chicks, after 24 h of feed deprivation, were immersed in tap water (17 °C) for a few seconds. Under chloroform anaesthesia ten chicks from each group were killed 1, 2 and 3 h after the stressing. The morphometric analysis of gizzard erosion (GE) and histopathological examinations of gizzards were performed for each chick. In Experiment B, 32 one-day-old broilers of both sexes were used. The control group was untreated (n = 16) while the CIM group (n = 16) was fed the same diet supplemented with 10 mg of cimetidine per kilogram of feed throughout the fattening period (42 days). The results of Experiment A showed decreased mean length of the GE in the cimetidine-treated birds as compared with the GE lesions of the controls. In Experiment B, the treated chicks had reduced liveweight (1835.1 g), carcass weight (1474.6 g) and increased feed consumption (2115 g of feed per kilogram of weight gain) compared to the controls in which the same parameters were 1898.5 g, 1574.2 g and 1797 g, respectively. The results show that while stress-induced GE of chicks can be medicated pharmacologically, long-term application of the same substance impairs the results of fattening
