The effect of cassava peel (CPL) incorporation (0,5, 10 and 15%) in the diets of growing snails  (average initial weight  66.0 ± 0.15 g) on the growth performance, shell morphological changes, digestibility of nutrients, carcass yield and mineral element composition of the meat was investigated. The nutritional trial adopted four T1 (0%), T2 (5%), T3 (10%) and T4 (15%) almost isocaloric and isonitrogenous diets. Two hundred and forty growing snails were randomly allotted at 60 snails/treatment, while each treatment was replicated three times. The digestibility of nutrients was evaluated at the 12th of the fourteen-week trial. Data collected were analyzed in a complete randomized design using (ANOVA), a significant difference among the means was separated using Duncan's multiple range test. Cassava peel is rich in NFE (70.0%), low in crude protein (3.94%), while the four diets held almost equal proximate composition. Feed intake increased (P<0.05) from T1 to T4 and T1 (control) had the best (P<0.05) carcass yield. Survivability of snails at all levels was 100%. Highest dry matter digestibility (70.01%) was obtained in T1; the digestibility of other nutrients also reduced (P< 0.05) with CPL incorporation. Meat mineral composition was not compromised by the treatments. Cassava peel based diet was favourably utilized at 15% CPL incorporation without any adverse effect on feed intake, growth, meat quality and carcass yield, farmers should adopt it.

Enzyme supplementation in diets based on corn and soybean meal can improve the productive performance of broilers. Thus, we aimed to evaluate the effect of the inclusion of different levels of an enzyme complex consisting of phytase, protease, xylanase, ?-glucanase, cellulase, amylase, and pectinase, for diets based on corn and soybean meal, on the parameters of carcass yield and meat quality of broilers. Six hundred broiler chicks were used, and the animals were females with one day of age, from the Cobb 500 strain, and distributed in a completely randomized design, with five levels of inclusion of the enzyme complex (0, 100, 200, 300 and 400), and six repetitions, with twenty animals each. The carcass yield and meat quality were evaluated at 35 and 42 days of age. We evaluated the characteristics of weight loss by cooking (WLC), shear force (SF), water holding capacity (WHC), pH, lightness (L*) and color (a* and b*). The parameters of performance, carcass yield and carcass parts, and meat quality were not affected by the enzyme supplementation of diets fed to broiler chickens (P >0.05), except for the performance characteristics of the breast and the wings at 42 days of age (P < 0.05).

This study aimed to evaluate the Texel lambs’ meat quality fed with increasing levels of crude glycerin (0, 7, 14, and 21% of dry matter) in the diet. Thirthy-two-two non-castrated male Texel lambs were used, with initial weight of 15.9 ± 4.1 kg, using a completely randomized design with four treatments and eight repetitions, per treatment. Upon reaching the average weight of 35 kg, the animals were slaughtered. The meat chemical composition was similar among treatments (P>0.05) and total lipids and crude protein presented averages of 3.47 and 20.05 g 100g -1, respectively. No changes in pH, marbling, color, and water loss under pressure were observed. The shear force did not change among treatments and the texture can be considered soft, with average values of 5.48 kgf. There was a linear (P0.05) were observed for the attributes flavor, tenderness, juiciness, and overall acceptance among treatments. Fatty acids in higher proportions in the meat lamb were to C18:1n-9 (1298.90 mg 100g-1), C16:0 (709.07 mg 100g-1) and C18:0 (433.30 mg 100g-1), with percentages of 42.72, 23.07 and 14.35%, respectively. Significant difference according to the glycerin level in the diet was observed only for the margaric acid (C17:0) with an increasing linear effect, reaching 58.95 mg 100g-1 muscle to the group with 21% crude glycerin, corresponding to 1.77% of total fatty acids. The other fatty acids did not change, and provided a satisfactory result for conjugated linoleic acid (CLA), totaling about 6.1 mg 100 g-1 muscle, corresponding to 0.21% of total lipids. The use of glycerin in the diet for finishing lambs does not alter the characteristics of the meat, maintaining the product quality for consumption.

The research was conducted to study the effect of heat stress on carcass characteristics and meat quality in indigenous sheep. Nine sheep were divided into three groups which were almost similar in age, sex and weight. Three groups were divided as zero hour (T0), four hours (T4) and eight hours (T8) heat exposure to direct sunlight. During experimental period temperature–humidity index (THI) value was calculated as 27.09 which indicated T4 and T8 groups were subjected to heat stress condition for at least four hours and eight hours respectively every day. Slaughter weight, body length and heart girth had no significant difference among the treatment groups. Dry matter, ash and ether extract had no significant difference (p>0.05) among the treatment groups but crude protein were increased with the increase of heat stress from T0 to T8 group (p<0.05). Drip loss was increased (p<0.05) in non-exposure group than treated groups but there is no significant result (p>0.05) found in pH and cooking loss. Carcass weight and eye muscle area had no significant difference (p>0.05) among the treatment groups but dressing percentage was decreased with the increase of time in heat treated groups (p<0.01). Significant difference (p<0.05) were found in weight of heart, kidney, lung + trachea and pluck between control and heat treated groups. The significant difference (p>0.05) in empty gut was found in gut with content and gut fill in heat treated groups. It can be concluded that heat stress had significant changes on carcass characteristics and meat quality of indigenous sheep.DOI: http://dx.doi.org/10.3329/bjas.v43i2.20717 Bang. J. Anim.

Recycled paper products were evaluated as litter material for broilers; parameters were growth performance, carcass quality, and footpad problems. One hundred sixty-eight broiler chicks were raised to market age (42 d) in an open-sided poultry house located at the Lajas Agricultural Experiment Station Small Animal Research Farm. Birds were assigned to 12 floor pens bedded with either rice hulls (RH) as control; a 50:50 mix of RH and shredded white paper (SWP); or a 50:50 mix of RH and shredded newspaper (SNP) according to a completely randomized design replicated four times. Traits measured were body weight, feed intake, feed conversion, carcass yield, breast blister score, footpad burn score, and mortality. Litter moisture percentage was assessed at 14, 28, and 42 d of age. Litter material had no influence on body weight, breast blister score, or bird mortality. However, birds raised on SWP had lower feed intake and higher body weight than those raised on RH and SNP. No significant differences in feed conversion were observed among treatments from 7 to 28 d of age. At 35 and 42 d, birds raised in SWP had significantly lower feed conversion than controls, whereas feed conversion of birds raised in SNP did not differ from that of the other treatments. No differences were found for carcass yield among treatments. At all sampling times, litter moisture percentage was significantly higher in SNP than in the control. No litter caking problems were observed in any of the treatments. Significant differences in footpad burn scores were observed among all treatments, with birds raised on SNP having higher scores (severer lesions), than those on SWP and RH.The results suggest that recycled paper products could be an excellent alternative bedding material for broilers. The use of SWP as litter appears to improve broiler performance and reduce the incidence of footpad problems.

The study examined the effect of cooling on the reproductive performance of gilts using 27 Large White Experimental Gilts on a Completely Randomized Design (CRD) with 3 systems of cooling, namely Wallow Cooling (WC), Sprinkler Cooling (SC) and Zero Cooling (ZC). Gilts were weighed at the commencement of the experiment and thereafter fed ad libitum from service to farrowing. Feed intake till farrow, feed cost, gilt weight at farrow, date of farrow, litter size and weight were recorded. The feed/piglet weight, feed intake/litter, feed cost/litter and birth weight/piglet were derived. The results showed that feed intake per litter and feed per piglet weight were highest for gilts placed on WC(P< 0.05), followed by SC and least for sow placed on ZC; gilt weight before farrow was highest for sow placed on SC (69.78±0.92), followed by ZC (69.33±0.94) and least for gilts placed on WC (67.33±0.87); litter sizes of gilts placed under the WC and SC systems were similar (5.6±0.41) while that under the ZC system was comparatively smaller (5.4±0.40);while the date of farrow was lowest in the ZC system (113.8±0.32) followed by SC (114.0±0.33) and highest under the WC (114.1±0.33). However, the feed intake per litter, feed per piglet weight, litter sizes of gilts, birth weight per piglet of gilts and the average date of farrow among gilts placed on WC, SC and ZC were not statistically different at 5% level of significance. Though, there is no significant difference in the performance among gilts placed on WC, SC and ZC, temperature regulation through provision of efficient cooling system in piggery would help to increase litter size, improve feed intake per litter and reduce the average cost of feeding gilt per day in maximizing reproductive performances in pigs.Keywords: Cooling, gilts, service, farrow, piggery, litter size, piglet and birth weight

Maggot black soldier fly (Hermetia illucens) is a protein source of feed which is highly favored by poultry, especially ducks and chickens. However, it is feared that the provision of live maggot in ducks will affect the organoleptic quality of the egg, especially its taste and aroma. Therefore this study aims to determine the organoleptic quality of duck eggs fed Hermetia illucens maggot feeds in a living state. The study used 120 alabio ducks which were placed in a postal cage. The design used was a completely randomized design, each treatment using six replications. Each replication is taken egg sample to be tested panelists. The panelists used were 67 panelists who were somewhat trained. The data obtained were analyzed of variance and Duncan's multiple range test. The treatments that were tried consisted of P1: low protein rations without live maggot, P2: low protein rations with live maggot administration 40 g/bird/day, P3: high protein rations without live maggot administration, and P4: high protein rations with live maggot administration 40g/bird/day. The results showed that the treatment affected the texture, flavor, and aroma of boiled eggs. Ducks fed with high protein ration coupled with the provision of live maggot 40 g/bird/day produce softer textures, tastes quite good, and aroma more fishy. Keywords: Maggot, duck eggs, organoleptics
