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.

A Value

The effect of varying dietary protein and calorie levels on the growth, survival and nutrient utilization of 540 brackish water catfish (Chrysicthys walkeri) fry average liveweight of 0.14g was investigated in a 3x3 factorial experiment with 3 calorie levels ( 2800, 3000 and 3200 Kcal ME/Kg diet) and 3 levels of crude protein (36%, 39% and 42%) giving a total of 9 diets, fed to the fish for a period of 56 days. Mean weight gain, specific growth rate, feed conversion ratio, survival and protein productive value were significantly higher (P<0.05) in fish fed diet 6 (3000 Kcal ME/Kg and 42% crude protein) when compared to other diets. Weight gain was highest in diet 6 with a value of 0.64g and lowest (significantly P<0.05) with a value of 71.67% and lowest in diet 1 (2800Kcal ME/Kg and 36% crude protein) with a value of 53.34%, while protein productive value was higher in diet 6 (78.40) and lowest in diet (2800Kcal ME/Kg, 39% crude protein) with a value of value of 64.33%. Thus, C. walkeri for survived and performed best when fed on 42% crude protein and 3000Kcal ME/kg diet.

Milk Component

This study was conducted to evaluate the effect of protein supplementation at 12%, 14% and 16.41% crude protein (CP) levels on the milk yield of West African dwarf dams. A total of twelve lactating dams, which were intensively managed and hand-milked on weekly basis were used for the study. Feed intakes, weight gain, feed conversion ratio (FCR) and protein efficiency ratios (PER) were monitored. Milk and blood samples were taken. The udder morphometry and milk composition were determined. Result showed that the dry matter and crude protein values ranged between 89.7 and 90.1% and 11.51 and 14.88% respectively. Dams on 12% protein supplemented feed recorded the highest daily dry matter intake (DMI) of (203.63 g/day) while, 16% protein supplemented feed had the least DMI (195.54 g/day). The value of crude fiber ranged between 9.98 and 13.31% while the value of ash ranged between 6.23 and 9.99%. Also, the values of ether extract ranged between 2.88 and 6.65%. Dams on 16% protein diet gained significantly (p<0.05) more weight (106.19g/day) and had the least feed conversion ratio (1.88). Milk component and nutrient digestibility did not vary among diets except for ether extract that was least in dams on 16% CP level. Dams on 14% and 16% protein diet supported the highest calcium concentration. Udder parameters and blood indices were not significantly (p>0.05) influenced by dietary protein levels. The rectal, espiratory and pulse rate were within the normal range. Pulse rate was more normal in dams on 12% and 16% dietary protein level. It can therefore be concluded that 16% crude protein level could be used for lactating West African dwarf dams to improve milk production and health condition of lactating dams.

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.

The objective of this work was to evaluate the effect of sustained swimming and dietary protein levels on growth and hematological responses of juvenile pacu (Piaractus mesopotamicus). A completely randomized design was used in a 3x2 factorial arrangement, with three levels of dietary protein (24, 28, and 32% crude protein), two rearing conditions (sustained swimming or motionless water), and 15 replicates. Fish were subjected to sustained swimming at the velocity of two body lengths per second (2 BL s-1), for 45 days. The level of dietary protein and the swimming conditions affected the performance, growth, and hematological profile of pacu. Swimming conditions influenced nutritional factors, increasing daily weight gain, specific growth rate, number of erythrocytes, mean corpuscular volume, and mean corpuscular hemoglobin. Fish under sustained swimming and fed with 24% crude protein showed better growth performance, with higher specific growth rate (4.11±0.88) and higher daily weight gain (2.19±0.47 g per day). Sustained swimming can increase the productive performance of pacu and simultaneously reduce dietary protein levels.

The use of Silkworm (Anaphe infracta) pupae as a protein source was investigated for its ability to replace fishmeal in the diet of Clarias gariepinus, African cat fish. Five dried diets formulated at 40% crude protein were fed to fingerlings of an average initial weight of 14.33g at 0 (control diet), 25, 50, 75 and 100% inclusion levels of silk worm meal. The experiment was conducted for 84 days were measured. Mean weight gain (MWG), specific growth rate (SGR), feed conversion ratio (FCR). The five inclusion levels of silk worm pupae supported the growth of Clarias gariepinus fingerlings, the growth and feed utilization were favoured by high inclusion level of silk worm meal. Significant differences (p<0.05) were observed among the treatments, although there were no significant differences (p>0.05) in the growth parameters between 50% and 75% inclusion levels. The 100% silk worm pupae meal inclusion gave the best final mean weight gain of 10.29g specific growth rate of 0.93%, feed conversion ratio of 2.18 and protein efficiency ratio (PER) of 0.012. The carcass protein and lipid contents increased compared to the levels of both at the beginning of the experiment. Even though, there were no significant differences (p>0.05) among proximate composition of the fish groups fed 25, 50 and 75%. The results showed that diet consists of 100% silk worm meal could be used as a complete replacement for fish meal in the diet formulation for Clarias gariepinus fingerlings.

Abstract Appreciative dietary desires and fabrication of fish nourishment is vital to the progress, sustainability of aquaculture and for the advanced feed mill rehearsal. Organizing fish feed includes choosing the exact feed, using an acceptable feeding technique, work out the feed charge and ensuring the cost efficiency of fish farm. The purpose of our present study was to feed the fishes with four different feeds and assessment of growth performance by length weight relationships. The growth analysis was executed by measuring FCR and related indices in gift tilapia oreochromis niloticus. Four feed composition was selected without any chemical contamination. In the present study fishes were collected from the golden farm, Neyyattinkara, Thiruvananthapuram district, South India. Fishes were introduced into four different tanks of well oxygenated good quality water. In each experimental tank, 20 fishes were introduced. For each experimental container a specific feed was fixed from 4 different diets. Every day feed was given to the fishes. They were fed two times for the period of 3 months. They were maintained to assess their growth performance. Four types of feeds used for the present study were control diet, diet 1, diet 2 and diet 3. Length and weight were measured on every 15 days interval for growth estimation. Based on the length-weight data, growth analysis was carried out by calculating relative growth (RG), relative growth rate (RGR), specific growth rate (SGR), feed conversion ratio (FCR) and the Fulton’s condition factor. The results of mean length in diet3proved the highest length of 6.455±0.46cm and diet one contain lowest length of 5.03±0.68cm. Highest weight of 96.8 ± 0.37g was recorded in diet3 and lowest weight obtained for the control diet (3.645 ± 0.306 g). In growth analysis the relative growth of fish was estimated in diet 3 having high relative growth (11.91). Relative growth rate was elevated in diet 3(1.5597). The upper limit of specific growth rate was 1.9146% noticed in diet 3. The feed conversion ratio was maximum in diet 3 (58.06) and minimum in control diet (36). The highest k value in Fulton's condition factor was noticed in diet 3(88.32).All experimental results proved that live Azolla [D3] was a superior feed for the present trials.

This study aimed to evaluate the impact of plant-based food additives on growth performance, body composition and survival of Nile tilapia. Four isonitrogenous (25% CP) and isolipidic (13% CL) experimental diets were prepared and designated as R1, R2, R3, and R4. R1 contains (3% Cymbopogon citratus), R2 contains (3% Ocimum basilicum), R3 contains (3% Mentha spicata) and R4 (control or 0% additive). 180 Nile tilapia fry with an initial average weight of 0.2g were distributed in 12 plastic tanks (50 L/tank) at the stocking density of 15 fish per tank in an isolated system. Fish were fed with experimental diets 3 times per day (8:00 am, 1:00 pm and 5 :00 pm) for 3 months. After 90 days of experiment, the results revealed that the final average weight ranged from 2.62g to 8.00g, the absolute average weight gain (AAWG) from 2.42 to 7.8g, the feed conversion ratio (FCR) from 1.31 to 2.67 and specific growth rate (SGR) from 3.06 to 4.36%/d. The survival rate (SR) varied between 64 and 100%. Of the parameters studied such as the absolute average weight gain (AAWG), the specific growth rate (SGR), the feed conversion ratio (FCR), and the survival rate, the best were obtained by the group of fish fed with the R2 diet containing 3% Ocimum basilicum. The results of the analysis of the flesh showed that the addition of 3% O. basilicum does not modify the contents of dry matter, crude protein, and ash but slightly increased the fat content. Based on the results, the inclusion of natural plant-based food additive (3% Ocimum basilicum) in the diet of Nile tilapia improved the parameters of growth, feed efficiency, and survival.
