Егоров И.А., Егорова Т.В., Шевяков А.Н., Клейнерман Ю.Е КЛЮЧЕВЫЕ СЛОВА: РЫБНАЯ МУКА, ЦЫПЛЯТА-БРОЙЛЕРЫ, АМИНОКИСЛОТЫ, ЗООТЕХНИЧЕСКИЕ ПОКАЗАТЕЛИ, ИСПОЛЬЗОВАНИЕ ПИТАТЕЛЬНЫХ ВЕЩЕСТВ, КОНВЕРСИЯ КОРМА, КАЧЕСТВО МЯСА АННОТАЦИЯ: Исследования выполняли на 2 группах бройлеров селекции СГЦ «Смена» с 1- до 35-суточного возраста, при клеточном содержании птицы. Контрольная группа бройлеров получала полнорационный комбикорм растительного типа, сбалансированный по всем питательным веществам, а опытная - полнорационный комбикорм аналогичной питательности с включением изучаемой рыбной муки в количестве 5% до 21 суток и 3% - с 22 до 28 суток. С 29 суток рыбная мука исключалась из рациона. Рыбная мука содержала 3,66% влаги, 76,70% сырого протеина, 7,97% сырого жира. При этом содержание кальция составило 4,51% , фосфора - 2,62%, натрия - 1,10%; уровень лизина составлял 7,09%, а метионина + цистина - 3,36%. Живая масса бройлеров в возрасте 35 суток в опытной группе достоверно повысилась на 7,54% (р<0,001), а конверсия корма снизилась на 6,84%. Рыбная мука не оказала существенного негативного влияния на вкусовые качества мяса; содержание сырого протеина в грудных мышцах в опытной группе было на 3,35% выше, сырого жира - на 1,09% ниже, чем в контроле. Сделан вывод, что ввод высокопротеиновой рыбной муки в комбикорма позволяет получить хорошую сохранность, живую массу и приросты живой массы бройлеров за счет лучшего использования питательных веществ, причем улучшение продуктивности и меньшее использование синтетических аминокислот полностью окупает затраты на рыбную муку. PROTEIN-RICH FISHMEAL IN COMPOUND FEEDS FOR BROILERS EGOROV I.A.1, EGOROVA T.V.1, SHEVYAKOV A.N.1, KLEINERMAN YU.E.2 1 Federal Scientific Center “All-Russian Research and Technological Institute of Poultry” of Russian Academy of Sciences 2 Vetsnab, LCC The chemical composition of protein-rich fishmeal (produced by Vetsnab, LCC ) and its efficiency as protein additive for broilers were studied. The fishmeal contained (%): moisture 3.66; crude protein 76.70; crude fat 7.97; calcium 4.51; phosphorus 2.62; sodium 1.10; lysine 7.09; methionine+cystine 3.36. Two treatments of broilers (cross Smena-9, 1-35 days of age, 70 birds per treatment) were fed similar vegetable diets with equal nutritive value and reared in similar management conditions; in the experimental diets soybean meal was partially substituted by fishmeal at the levels 5% of total diet since 1 to 21 days of age and 3% since 22 to 28 days; since 29 days the treatments were fed similar vegetable finisher diets. Live bodyweight at 35 days of age in the experimental treatment was significantly higher by 7.54% in compare to control (p<0.001), feed conversion ratio lower by 6.84%. Sensory evaluation of breast and thigh meat evidenced the absence of negative impact of the fishmeal on the taste; concentration of crude protein in breast muscles was higher by 3.35%, crude fat lower by 1.09% in compare to control. The conclusion was made that supplementation of starter and grower diets for broilers with protein-rich fishmeal results in better productive performance and digestibility of dietary nutrients in compare to entirely vegetable diets without the deterioration of meat quality; better productivity in broilers and lower use of the synthetic amino acids in the diets entirely compensate for the fishmeal related expenses.

The eight-week feeding trial was conducted to evaluate the nutrient digestibility and growth performance of broiler chickens fed raw or processed Senna obtusifolia seed meal (SOSM). Six experimental diets were compounded to contain 0% SOSM and 20% each of the raw, boiled, soaked, sprouted and fermented SOSM respectively. Two hundred and sixteen (216) broiler chicks were randomly allotted to six (6) dietary treatments in a randomised complete block design with three (3) replicates containing 12 chicks each. Data were collected on nutrient digestibility, feed intake, weight gain, feed conversion ratio and mortality. The result of productive performance indicated that feed intake, weight gain and feed conversion ratio were significantly (P<0.05) depressed in broiler chickens fed raw, soaked and sprouted Senna obtusifolia seed meal. However, broiler chickens fed fermented SOSM showed better (P<0.05) productive performance that was close to those fed the positive control diet (0% SOSM). The mortality rate did not reveal any particular trend. However, the low mortality rate recorded in the different treatments indicated broiler chicken can tolerate up to 20% of either raw or processed SOSM. Broiler chickens fed raw SOSM recorded lower values for dry matter (63.06%), crude protein (52.46%), ether extract (53.88%), crude fibre (30.72%) and nitrogen-free extract (46.11%) digestibility than those fed the other processed SOSM. The nutrient digestibility of broiler chickens fed fermented SOSM was significantly (P<0.05) better followed by those fed boiled Senna obtusifolia seed meal. For instance, broiler chickens fed fermented Senna obtusifolia seed meal recorded the highest crude protein and ether extract of 69.91 and 70.03% compared to the other processing methods. It can be concluded that 20% fermented SOSM can be incorporated in the diets of broiler chickens with acceptable depreciation in biological performance. Slightly lower levels of boiled SOSM can be included in the diet of broiler chickens but the levels should be ascertained in further studies.

SUMMARY1. Weanling male rats were used in three experiments to evaluate the sequence of limiting amino acids for maximum growth with diets based on wheats containing 10, 13 or 17% crude protein (N×5·71).2. Lysine was the first-limiting, threonine the second-limiting, and valine or methionine the third- or fourth-limiting amino acid for growth rate and feed-conversion ratio of rats offered the diet based on wheat containing 10% crude protein. A further four amino acids (isoleucine, histidine, tryptophan and tyrosine) were limiting for feed-conversion ratio only.3. For the diet based on wheat containing 13% crude protein the sequence of limiting amino acids was lysine, threonine and methionine.4. Only lysine was limiting in the diet based on wheat containing 17% crude protein.5. Plasma-free amino-acid concentrations were found to be a valuable criterion for prediction of the first-limiting amino acid in diets.6. Improvement of growth and feed-conversion ratio was observed with diets based on wheat containing 17 or 13% crude protein when the limiting amino acids were supplemented to provide the recommended allowance. Further improvement in feed-conversion ratio was obtained when lysine and threonine were provided in excess of the recommended allowances.7. There was a lysine-threonine interaction affecting growth rate and feed-conversion ratio, and a lysine-me.thionine interaction affecting feed-conversion ratio.

This article describes a new idea about using Bifidobacteriumsp isolates as an alternative to antibiotic growth promoters, based on the ability of Bifidobacteriumsp isolates, which have the potential as a probiotic in laying hens. This study aims to prove that Bifobacteriumsp could improve production performance, including feed conversion ratio, feed efficiency, and nutrient intake (feed intake, crude protein intake, crude fiber intake, lipid intake, and organic matter). A total of 150 laying hens at 25 weeks of age were divided into three groups (P0: control, P1: 0.1% antibiotic growth promoters, P1: 0.05% Bifidobacterium spp. probiotic) and fed on a basal diet containing 2750 kcal/kg metabolizable energy and 18% crude protein for four weeks. The different supplementation to the basal diets showed significant differences (p<0.05) on feed conversion ratio, feed efficiency, feed intake, crude protein intake, crude fiber intake, lipid intake, and organic matter intake among the treatments. However, feed intake, feed conversion ratio, crude protein intake, crude fiber intake, lipid intake, and organic matter intake were lowest in the group fed with 0.5% of Bifidobacterium spp. The highest feed efficiency was obtained from the groups fed with 0.5% of Bifidobacterium spp, compared with the control and supplemented antibiotics growth promoters group. 0.5% of Bifidobacterium spp. supplementation to the diet of laying hens is beneficial for increasing feed efficiency and improving feed conversion ratio. The practical and theoretical significance of the results is that Bifidobacterium spp. can be used to improve production performance in laying hens.

Abstract The purpose of the study was to obtain preliminary data on the effect of dietary protein on the growth of the thick-lipped grey mullet (Chelon labrosus) juveniles reared in net sea-cages. The juveniles (6.2 ± 0.61 g) were obtained from the wild and were stocked into net sea-cages at a stocking rate of 100 juveniles per cubic meter and fed with experimental diets including 25, 30, or 35% crude protein for 87 days. The highest mean weight and specific growth rate (SGR) were 39.5 g and 2.13% day−1, respectively, at protein levels of 30%. The diet also resulted in the most efficient feed conversion ratio of 1.61.

This study was conducted to compare productive performance between purebred Thai indigenous black-bone chickens and their reciprocal crossbreds. Four different genetic groups were studied: 2 purebreds (Chee Fah and Fah Luang) and 2 crossbreds (Chee Fah ´ Fah Luang and Fah Luang ´ Chee Fah). The results showed that Fah Luang ´ Chee Fah had the significantly highest body weight at birth and 20-week of age, while the lowest values were found in Chee Fah ´ Fah Luang (p less than 0.05). For feed conversion ratio, Fah Luang ´ Chee Fah had greater potential than purebreds and Chee Fah ´ Fah Luang (p less than 0.05). Additionally, Fah Luang ´ Chee Fah grew faster than the others (p less than 0.05). The productive performance of crossbred chickens was more favorable than purebreds. Considering crossbreds, Fah Luang ´ Chee Fah showed greater performance than Chee Fah ´ Fah Luang. Therefore, Fah Luang had more potential for using as a sire than Chee Fah.

The objective of the study was to evaluate the effects of expanded diets on growth performance, meat quality, and carcass characteristics in finishing pigs. A total of 80 finishing pigs [(Landrace × Yorkshire) × Duroc] were randomly allotted to two dietary treatments: 1) unexpanded corn-soybean meal diets; 2) expanded corn-soybean meal diets. Each treatment consisted of ten replicate pens with four pigs (2 gilts and 2 barrows) per pen. There were no differences in daily feed intake and daily gain throughout the experiment (P less than 0.05). However, expanded diets decreased feed conversion ratio compared with unexpanded diets (P less than 0.05). Expanded diets had no effect on carcass characteristics and meat quality with the exception of increased sensory evaluation (color) of meat compared with unexpanded diets (P less than 0.05). In conclusion, expanded diets can improve feed conversion ratio but have no effect on daily gain and daily feed intake and sensory evaluation of meat color.

Two experiments were conducted to examine the nutritive value of yellow lupins for weaner pigs. Using a completely randomised block design, Experiment 1 was conducted to determine the optimum inclusion level for yellow lupins (cv. Wodjil) in the diet of weaner pigs (6.14 kg ± 0.278). Experiment 2 was conducted using a 2 × 2 factorial design to examine whether supplementation of an enzyme preparation (VegPro) either in a soybean meal-based diet (0 g/kg yellow lupins) or in a yellow lupin-based diet (150 g/kg) improved performance of piglets (6.17 kg ± 0.317). In Experiment 1, the feed conversion ratio significantly increased at week 1 (linear effect, P = 0.040) and at week 3 (quadratic effect, P = 0.010) as the concentration of yellow lupins increased in the diet. In Experiment 2, supplementation with the enzyme preparation improved the feed conversion ratio in the pigs fed the lupin-based diet only but not in the pigs fed the soybean meal-based diet in week 2 (interaction P = 0.001). The results indicate that the optimum inclusion levels of yellow lupins for piglets immediately after weaning was 150 g/kg, and supplementation of a multi-enzyme preparation to a yellow lupin-based diet for the weaner pigs improved performance relative to the soybean meal-based diet.

The effect of fermentation of cassava tuber followed by its gelatinization was evaluated as a method of processing cassava for use as source of energy in broiler diets. Peeled and unpeeled cassava tubers were separately fermented in water for 4 days, dried in the sun and then milled to produce fermented peeled and unpeeled cassava tuber meals, respectively. The dusty meals were then gelatinized by mixing with water in pots seated over fire at the rate of 1kg of cassava tuber meal to one litre of water and stirred until they gelatinized into fufu. The gelatinized pastes were then taken bit by bit and flattened on polythene sheets and dried in the sun. The resultant fermented and gelatinized peeled and unpeeled cassava tuber cakes were then milled to produce fermented and gelatinized unpeeled cassava tuber meal (UFGC), a brownish-looking non-dusty product and fermented and gelatinized peeled cassava tuber meal (PFGC), an ash-looking non-dusty product. Three broiler diets were made such that diet 1 (control) contained maize as source of energy, while in diets 2 and 3, the maize in the control diet was completed replaced with UFGC and PFGC, respectively, both in the starter and finisher diets. One hundred and twenty (120) broiler chicks were divided into 3 groups of 40 birds each and each group assigned to one of the diets, using completely randomized design, and fed for 4 weeks with the starter diets and finisher diets for another 4 weeks. At the starter phase, the UFGC diets gained significantly (P < 0.05) less weight and consequently had poorer feed conversion ratio. There were no significant differences in feed intake (P < 0.05). At the finisher phase, the group on UFGC gained significantly (P < 0.05) more body weight. The groups on cassava diet tended to consume less feed and so had better feed conversion ratio. There were no differences (P > 0.05) in dressed weights and weights of internal organs but the group on PFGC diet accumulated significantly (P < 0.05) more abdominal fat.
