Weaning Age

To determine the effect of a weaning program on growth performance, nutrient digestibility, and serum parameters in Hu lambs, 48 newly born twin lambs (2.53 ± 0.13 kg; 24 male and 24 female) were randomly divided into four treatments: ewe reared (ER) or weaned at 10, 20, or 30 days post birth (EW10, EW20, and EW30) and fed milk replacer (MR). All liquid feed were eliminated at 60 days of age. Creep feed was offered ad libitum to all lambs from 15 to 90 days of age. The results indicated that lambs fed MR had higher liveweight, average daily gain, and creep feed intake (P < 0.001) than those in the ER group. There were no differences between treatments in the apparent digestibility of dry matter, organic matter, nitrogen or phosphorus (P > 0.05) from 50 to 60 days of age. The apparent digestibility of dry matter, organic matter, nitrogen and phosphorus of EW20 and EW30 groups were significantly higher (P < 0.05) than that of EW10 and ER groups from 80 to 90 days of age. Lambs in the EW10 group had higher concentration of albumin, serum urea nitrogen, and immunoglobulin G levels than those of other groups (P < 0.05). In conclusion, early weaning could improve creep intake, growth performance, and nutrient utilisation of Hu lambs. Early weaning age had a significant effect on the growth of lambs.

Insects are emerging as a sustainable alternative to fishmeal and fish oil in aquafeeds. This study assessed the effect of graded incorporation levels of defatted yellow mealworm (Tenebrio molitor) protein meal on juvenile rainbow trout (Oncorhynchus mykiss) growth performance, body composition, and apparent nutrient digestibility. The trial comprised five dietary treatments: control diet with 25% fishmeal, and four experimental diets with yellow mealworm protein meal at 5%, 7.5%, 15%, or 25%, which corresponded to a fishmeal replacement of 20%, 30%, 60%, or 100%, respectively. After 90 days, the graded incorporation of insect protein meal led to a significant stepwise increase in final body weight, and a significant improvement of specific growth rate, feed conversion ratio, and protein efficiency ratio compared to the control treatment. Regardless of the incorporation level, the insect protein meal had no effects on fish whole-body composition and apparent digestibility coefficients of dry matter, protein, fat, phosphorus, and energy. Protein, phosphorus, and energy retention significantly increased in fish fed the diets with an insect protein meal. In conclusion, the yellow mealworm protein meal could effectively replace 100% of fishmeal in the diet of juvenile rainbow trout with positive effects on its overall zootechnical performance.
