Probiotics are beneficial bacteria that had been used in poultry industry as alternative sources for antibiotic. The aim of this study was to determine the effect of probiotic mixed with cassava leaves (Manihot esculenta) on Cherry Valley Duck (Anas platyrhynchos domesticus) growth performance, carcass characteristics and meat quality. Lactobacillus spp. was used in this experiment to see its effectiveness in enhancing quality of cassava leaves as potential feed towards optimum growth performance of ducks like body weight gain, feed intake and feed conversion ratio, carcass characteristics and meat quality. 34 tails of Cherry Valley ducks aged 14 days with average weight of 500 g were randomly assigned to four treatments in triplicates. Treatments for the 35 days feeding trial were T1 at 0% probiotic + 75% commercial diet + 25% cassava leaves (control), T2 (0.15% probiotic + 75% commercial diet + 25% cassava leaves), T3 (0.30% probiotic + 75% commercial diet + 25% cassava leaves) and T4 (0.45% probiotic + 75% commercial diet + 25% cassava leaves) respectively. Proximate analysis was also conducted to determine nutritional content like protein, lipid, moisture, ash and fiber. Results show that supplementation of probiotic at 0.15% Lactobacillus spp. into 25% of cassava leaves and 75% commercial pellet gave highest body weight gain (BWG), low feed conversion ratio (FCR), highest carcass yield and good meat quality. It can be concluded that inclusion of probiotic at 0.15% in cassava leaves as duck’s diet gives good growth performance and may become an alternative super diet for duck in future.

Using black soldier fly (BSF, Hermetia illucens) larvae as a novel protein source substituting fishmeal (FM) in animal feeds is globally gaining momentum. BSF can be reared on agro-industrial residues. However, incorporating BSF larval meal (BSFLM) into finisher pig diets has received inadequate attention. This study evaluated the effects of replacing dietary FM with BSFLM on growth, carcass traits and meat quality of finisher pigs. A control diet (including FM: 0% BSFLM) was compared with four dietary levels of replacement of FM with BSFLM at 25, 50, 75 or 100%. Forty hybrid pigs (crossbreeds of purebred Large White and Landrace) were randomly allocated to the five different dietary treatments. Feed intake, body weight gain and feed conversion ratio were measured. After 98 days of feeding, all pigs were slaughtered for the evaluation of carcass and nutritional content of the organ and muscle tissues. Diet significantly affected pig growth performance. Carcass weight of pigs fed diets with BSFLM replacing FM by 50, 75 or 100% (w/w) was higher than for pigs fed control diet with 100% FM as protein source. Crude protein content of pork tissues was high (65-93% on dry-matter basis) across all dietary groups. Therefore, BSFLM can replace FM in pig feed. This is relevant for commercial pig feed production and provides for the first time a nutritional analysis of pork derived from pigs raised on BSFLM.

Fish with average initial body weight of 33,61 g were reared in hapa (2×2×1 m<sup>3</sup>) at density of 30 ind/hapa. Fish were hand-fed with experimental diet to satiety twice daily for 60 days. Experimental design was set in completely randomized design. Each treatment was done in triplicates. Experimental diets were a commercial diet to contain four differennt levels of protein; i.e. diet A (18%), diet B (23%), diet C (28%), and diet D (32%). Specific growth rate (SGR), feed conversion ratio (FCR), protein (RP) and lipid (RL) retention, hepatosomatic index (HSI), lipid and glycogen content of liver, protein and lipid content of meat, edible portion, and fillet textural were calculated. The results of the experiment showed that the highest weight gain and SGR, lowest FCR and meat protein were obtained in the group of fish fed 23%–32% protein diets.

Aims: An experiment was conducted to investigate the comparative efficacy of two probiotics of different origins (yeast and bacterial based) on the growth performance and carcass characteristics of broilers chicken. Place and Duration of Study: The study was conducted at Krishi Vigyan Kendra, Purnea between January, 2020 to March, 2020. Methods: Two hundred and forty, day old chicks were kept and were randomly divided into 4 groups (A, B, C and D) and each group had 2 replicates of 20 chicks. Four (A, B, C and D) iso-caloric and iso-nitrogenous (ME 3000 kcal/ kg and CP 21.56%) broiler starter and finisher (ME 3000 kcal/ kg and CP 18.75%) diets were formulated containing Saccharomyces cerevisiae, Bacillus cereus toyoi and mixture of both @ 0.2% except group A which was control. Birds were raised for first week on commercial diet. Broiler starter and finisher diets were fed from 8-28 and 29-42 days, respectively. Results: A significant (P<0.05) effect was observed on overall performance of the birds fed diet containing probiotics. Probiotics in feed at 0.2% Saccharomyces cerevisiae supplementation improved body weight gain (+12.7%), feed intake (3.8%) and feed conversion efficiency (-8.7%) compared with the control diet. Among groups, no significant differences were observed in carcass traits but highest dressing percentage was recorded in group-B followed by group-C than group-D and lowest in control group. Conclusion: The result indicated that the addition of probiotics in feed containing 0.2% Saccharomyces cerevisiae improved broiler growth performances and it is beneficial to be used as supplement in feed of broiler chickens.

The aim of the present study was to investigate the effects of induction hypothyroidism by propylthiouracil (PTU) on the growth performance and meat quality of fat-tailed Lori-Bakhtiari lambs. Eighteen Lori-Bakhtiari male lambs were randomly assigned to one of three groups (n = 6) and received daily treatments (gavage) consisting of 0 (Control: C), 10 (Low: L) or 20 (High: H) mg PTU/kg bodyweight/day for 60 days. PTU decreased plasma triiodothyronine and thyroxine concentration in both L and H (P < 0.0001). Lambs treated with PTU (L and H) had lower feed intake (P < 0.004), feed conversion efficiency (P < 0.003), and greater intramuscular fat than C lambs (P < 0.035). Meat from the L and H lambs had lower cooking loss and shear force, and also higher L* (lightness) than C lambs (P < 0.004, P < 0.015 and P < 0.025, respectively). The meat of H and L lambs was more tender than C lambs (P < 0.032). However, the meat of H lambs required fewer chews before swallowing than C lambs (P < 0.041). Generally, induction of mild hypothyroidism appeared to improve feed conversion efficiency and meat quality of lambs.

The purpose of the present study was to assess the effect of diets for market pigs with 20% inclusion of lupine seeds, cv. Amiga, on the performance, health status, carcass characteristics, fatty acids (FA) profile of meat lipids and nutritional and sensory parameters of meat. Another purpose was to increase the nutritional value of a cereal-lupine diet (E1) by supplementation with lysine, methionine, threonine (E2) or fat (E3) and to perform a comparison with control diets containing animal protein (C1) or soy (C2). The experiments were performed on 50 pigs (50% males, 50% females) with initial body weights of 35.6 &plusmn; 2.2 kg, fed isonitrogenic and isoenergetic diets partly <i>ad libitum</i> for 90 days. Feed intake was not adversely affected by lupine inclusion. The daily body weight gain (BWG) was significantly higher (<i>P</i> < 0.05) in group E3 in comparison with the cereal-lupine diet group (E1) and the other groups by 12.6 to 15.9% during the initial 30 days of experiment. The highest BWG (0.88 &plusmn; 0.07 kg/kg) during the entire experimental period was obtained with the fat containing diet (E3); that was non-significantly higher by 2.3 to 10.0% in comparison with the other diets. The feed conversion rate was reduced in groups E3 and E2 (2.55 and 2.58 kg/kg BWG) by 3.1 to 7.6% in comparison with groups C1, C2 and E1. No adverse effect of the lupine containing diet was observed on the carcass characteristics or the nutritional quality of the meat. Optimum content of linolenic acid in lupine seeds had a favourable effect on n-6/n-3 polyunsaturated FA ratio in meat lipids of group E3 in comparison with groups C1 and E1 (<i>P</i> < 0.05). By sensory meat analysis, significantly better characteristics were found for texture, juiciness (<i>P</i> < 0.01, <i>P</i> < 0.05) and taste in E3 in comparison with groups C1, C2 and E1. The obtained results indicate that animal and soy protein may be replaced with lupine, tested in the present study, in case a diet is supplemented with amino acids and fat.
