Summary1. The growth rate, feed-conversion ratio and blood composition of 14 twin calves were compared with those of 14 contemporary singletons.2. The growth rate and feed-conversion ratio from weaning to 3 months were similar for twin and singleton calves.3. The twin calves weighed significantly less at birth, weaning and 3 months of age but differences in weight were not significant at 1 year of age.4. The mean packed cell volume (PCV) and the mean concentrations of blood glucose and haemoglobin, serum albumin, urea nitrogen, calcium, inorganic phosphate, magnesium, potassium, sodium, copper, iron and total iron binding capacity, at 11, 12 and 13 weeks of age were similar in the two groups. Concentrations of globulin were significantly lower in the serum of twin calves than those in the serum of singletons.5. There was significantly less variation between twin calves than among offspring from different dams for PCV and concentrations of blood haemoglobin and serum potassium and calcium.6. The results did not reveal any overall disadvantage in twins as compared with singletons.

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.

ABSTRACTTwo temperature regimes were compared in relation to the growth and feed conversion ratio of groups of cage-reared pigs between 10 and 38 days of age. The treatments were: 27°C at 10 days reducing by 1°C every 4 days to 20°C at 38 days; and 27°C at 10 days reducing by 1°C daily to 20°C at 17 days and then remaining constant. Twelve replicates using 244 pigs were completed, the group size varying between 9 and 12 pigs. The mean growth rates on the two temperature regimes were respectively 234 and 243 g/day, and in both cases feed conversion ratio (kg DM/kg gain) averaged 1·03. It is concluded that temperatures lower than those currently recommended for pigs weaned at 14 to 16 days into controlled-environment houses would support satisfactory performance with direct savings in heating costs under winter conditions.

Eighty black Nera cockerel chicks were randomly alloted to four dietarey treatmants containing 0, 10, 20 and 30% kolanut husk meal (KHM) for twelve weeks. Significant differences (P<0.05) in feed intake, weight gain and feed conversion ratio were observed. Dietary inclusion of KHM depressed (P<0.05) growth rate feed conversion ratio and nutrition uilization of cockerels birds. There were linear reduction (P>0.05) in nitrogen retention and apparent crude fibre digestibility (ACFD) of  cockerels birds at each incremental KHM dietary levels. This indicated that KHM could be effeciently utilized by cockerels up to 205 dietary level above which the depression in growth rate occurs.
