Abstract This study evaluated the effect of different sources of nitrogen [soybean meal (SM); cottonseed meal (CM); cottonseed + urea (CU); and urea (U)] associated with spineless cactus on intake, digestibility, performance, carcass characteristics and meat quality of confined lambs. Forty male Santa Inês sheep, uncastrated, with initial body weight of 23.00 ± 1.66 kg were distributed in random blocks design and slaughtered after 58 days of confinement. Dry matter (DM) intake (1.16 ± 0.19 kg/day) did not differ (P > 0.05) between nitrogen sources, but the intake of crude protein (CP) and non-fibrous carbohydrates (NFC) was lower (P < 0.05) for sheep consuming CU. Sheep fed with diets containing U had lower digestibility of DM, CP and NFC (P < 0.05). The average daily gain (0.15 ± 0.04 kg/day) and the slaughter body weight (32.07 ± 2.86 kg) did not differ between nitrogen sources, but the cold carcass and loin weight was lower (P < 0.05) for sheep fed with U. The water retention capacity and meat protein content were greater (P < 0.05) for animals fed with SM. Soybean meal or cottonseed meal associated with spineless cactus-based diets for sheep meat production are recommended because it allows greater DM digestibilityand improves carcass characteristics and physicochemical composition of the meat.

A study was conducted to examine how lupin grains (LUPs) feeding affected nutritional intake, digestibility, growth, and carcass characteristics in kids. A total of 24 growing black kids (initial body weight (BW) = 16.4 ± 0.49 kg) were allocated to one of three diets at random. Lupin was included in the diet at a rate of 0 (control; CON), 100 (LUP100), or 200 g/kg (LUP200) of total dry matter (DM). The trial lasted for 91 days divided into 7 and 84 days to be used for adaptation and data collection, respectively. Feed intake was evaluated daily throughout the study. At the commencement and the end of the study, each kid’s body weight was measured to determine its average daily gain (ADG). On day 70, 5 kids were chosen at random from each group to investigate nutrient in vivo digestibility and N balance. At the end of the study, all of the kids were slaughtered to examine carcass features. Nutrient intakes (neutral detergent fiber, acid detergent fiber, and ether extract) were higher (p ≤ 0.01) in LUP-containing diets than in the CON diet. The average daily gain was greater (p ≤ 0.03) in diets containing lupin grains than in the CON diet. Cost of gain ($US/kg growth) was lower (p = 0.004) in kids fed diets containing lupin than the CON diet. Dry matter and CP digestibility rates were greater (p ≤ 0.03) in lupin diets. Retained N was higher (p = 0.04) in lupin-containing diets than in the CON diet. Cold carcass weight was higher (p < 0.05) for kids consuming the LUP100 diet than the CON diet. In lupin diets, carcass cut weights were higher (p < 0.05). Results of the current study indicate that feeding black kids diets containing lupin grains at 100 or 200 g/kg DM basis is cost effective and would increase profitability.

Ingestive Behaviour

Context The water buffalo (Bubalus bubalis) is a valuable species in part because it is a multipurpose animal; its milk, horns and skin are all useful, and its meat is rich and nutritious. However, water buffalo meat still suffers many marketing restrictions. Aims The present study evaluated performance, ingestive behaviour, carcass characteristics and meat quality. Methods We examined the meat of 24 Murrah water buffaloes that weighed 287.8±1.8 kg and were divided into four groups that received 0, 250, 500 or 750 g/kg dry matter (DM) of a 3:2 blend of spineless cactus–cottonseed (henceforth, referred to as the blend) for 125 days in a completely randomised design. Key results The inclusion of the blend resulted in diets with increased moisture and crude protein intake at 250 g/kg inclusion and reduced intakes of non-fibrous carbohydrates and total digestible nutrients per kilogram DM, which led to an increased DM intake, but significantly lower (P&lt;0.001) final bodyweight, average daily gain, and hot carcass weight, thus resulting in a significantly lower (P&lt; 0.001) growth efficiency. Moreover, there was a reduction in the ammonia-nitrogen concentration and time spent drinking (P≤0.05). The ruminal pH and time spent feeding, chewing and defecating increased (P≤0.05), the fat content and colour parameters of the water buffalo meat increased, and the shear force decreased (P≤0.05) in response to the inclusion of the 3:2 blend of spineless cactus–cottonseed in the diet. The time spent on both rumination and urination, most of the physicochemical properties, and the consumer appeal of the meat, were not affected by the inclusion of the blend (P&gt;0.05). Conclusion The 3:2 blend of spineless cactus–cottonseed is not an effective replacement for corn bran and soybean meal in buffalo diets because, despite improving the rumen pH, the blend reduces the performance and carcass characteristics of the water buffalo. However, the fat content, coloration and softness of the meat improved, which is of commercial importance. Implications The inclusion of the spineless cactus–cottonseed blend in place of the high-concentrate diet did not affect the consumer appeal of the meat. The meat characteristics were scored as ‘like moderately’ (6–7 on a 9-point hedonic scale). On the basis of the scores of the panellists, all of the meats were well accepted.

The objective was to evaluate the effect of partial or total replacement of Tifton 85 hay with fresh or dehydrated spineless cactus on performance and body weight components of sheep. Thirty hair lambs, with 19 kg ± 0.35 kg initial weight, were randomly divided into five treatments, namely: Tifton 85 Hay (HA); Tifton 85 Hay + fresh spineless cactus (HAFC); Tifton 85 Hay + dehydrated spineless cactus (HADC); fresh spineless cactus (FC); dehydrated spineless cactus (DC). In addition to the spineless cactus and hay, the complete mixture contained soybean meal, mineral salt and limestone in all treatments. Animals were confined for 75 days and then slaughtered. The weight of body components was recorded. Dry matter intake, total digestible nutrients intake and voluntary water intake were higher (p < 0.05) for the DC and HADC treatments. The average daily gain was 118 g day-1 and body weight at slaughter of 25.8 kg were not influenced (p > 0.05) by treatments. The cold carcass weight, rib eye area, weight and yield of the skin, liver, kidney and large intestine were higher (p < 0.05) for the DC and HADC treatments. Partial or total replacement of Tifton 85 hay with fresh or dehydrated spineless cactus, in complete diets for sheep, increases the weight of the cold carcass and non-carcass components.

Objective: The aim of this study was to determine the effect of pineapple cannery by-product (PCB) level on the growth performance and carcass characteristics of finishing Hanwoo steers.Methods: The feeding stage was divided into early and late finishing stages. A total of 60 castrated Hanwoo steers (13.9±0.8 months old, 418.8±36.5 kg initial body weight [BW]) were blocked by initial BW and then randomly allotted into 12 pens (five head/pen). The pens were randomly assigned to control (CONT), low PCB (LPCB), or high PCB (HPCB) treatments. These diets contained 0%, 1.5%, or 3.0% of PCB (on a dry matter [DM] basis; as-fed basis was 0%, 10.6%, or 21.2%), respectively.Results: For the early finishing stage, body weight gain (BWG) and average daily gain (ADG) of the CONT and LPCB feeding groups were greater (p<0.05) than those of the HPCB feeding group. In addition, there were linear and quadratic effects on BWG and ADG with increasing dietary PCB level (p<0.05). The gain to feed (G:F) ratio tends to quadratically decrease with an increasing PCB level in the early finishing stage (p = 0.076). Growth performances of late finishing stage were not affected by PCB level. The marbling score of the LPCB feeding group was similar to that of the CONT feeding group. However, there was a linear decrease (p< 0.05) in marbling score and quality grade among treatments as PCB was increased in the diet. In the <i>longissimus</i> muscle free amino acid profile, histidine composition increased linearly (p<0.05) with an increasing level of PCB.Conclusion: The level of PCB 1.5% DM in diet can be used for finishing steers without any adverse effects on growth and carcass performances. However, there were some negative effects on growth and carcass performance in the HPCB feeding group.

Background: Mineral deficiencies are considered to be one of the nutritional constraints to sheep performance. An experiment was conducted to evaluate the role of bole soil on feed intake, live weight change and carcass characteristics of Arsi-Bale sheep fed natural grass hay and concentrate supplement and its cost-benefit analysis of bole soil supplementation. Result: Total DM, OM, CP, NDF, ADF intake and ADL were higher (p less than 0.0001) for T3 than for T1, T2 and T4. Final weight, body weight change, average daily gain and feed conversion efficiency were greater (p less than 0.0001) for T3 and T2 than for T1 and T4. There were no differences (p greater than 0.05) between T3 and T2 whereas T4 was greater than T1 in these variables. Slaughter weight (SW) was heavier (p less than 0.0001) for treatment two and treatment three than for treatment four and treatment one, hot carcass weight, foreleg weight and dressing percentage on empty body weight basis were greater (p less than 0.0001) for T3 and T2 than for T1and T4. Conclusion: Bole soil supplementation had potentially highest effect on feed intake, live weight change and carcass characteristics of Arsi-Bale sheep than non-supplemented groups. The present study also revealed that supplementation of minerals improved the total weight gain of sheep over the control treatment.

ABSTRACT: This study evaluated the effect of dietary net energy (NE) levels on growth performance and carcass characteristics of barrows from 30 to 70 kg of body weight (BW). Sixty barrows with initial body weight (IBW) of 31.94 ± 3.54 kg and final body weight (FBW) of 71.98 ± 5.99 kg were allotted to one of five dietary NE levels (2.40, 2.45, 2.50, 2.55, and 2.60 Mcal kg-1), using a completely randomized block design with six replicates and two barrows per replicate. The experimental period was divided into phase I: 30 to 50 kg and phase II: 50 to 70 kg. The variables analyzed were average daily feed intake (ADFI), net energy intake (NEI), digestible lysine intake (LysI), average daily gain (ADG), feed conversion (FC), FBW, digestible lysine conversion:gain (LysI:G), Cost:Gain (C:G), loin eye area (LEA), muscle depth (MD), first backfat layer (BF1), second backfat layer (BF2), total backfat (BFt), lean meat percentage, and carcass bonus index (BI). In phase I, there was a linear increase (P < 0.05) in FBW, ADG, NEI, and LysI with increasing NE levels in the diet. In phase II, increasing dietary NE levels also increased (P < 0.05) FBW, ADG, NEI, LysI, and FC linearly. Overall, there was a linear increase (P < 0.05) in ADG, NEI, LysI, and FC with increasing NE levels in the diet. The other performance variables were not affected (P > 0.05) by the NE levels. There was an increase (P < 0.05) in BF2 with increasing NE levels, but the other carcass characteristics were not altered (P > 0.05). We recommended 2.60 Mcal of NE kg-1 in the diet for growing barrows from 30 to 70 kg.

Background and Aim: The rearing of quails can have a stronger attraction for the breeders if we lower the cost prices by introducing by-products in their feed formulas. The aim of this study was to evaluate the effects of the partial substitution of soybean meal by apricot kernel cake (AKC) in the diet of quails, applied either sequentially or during all phases of rearing, on their growth performances, carcass characteristics, and meat physicochemical composition. Materials and Methods: A total of 600 one-day-old quails (Coturnix coturnix japonica), with equal sex ratio and weighing on average 7±0.2 g, were randomly distributed in one control group and three experimental groups, the latter being designed according to the rate of application of AKC in either sequential or non-sequential mode in different rearing phases. Each group was divided into five replicates of 30 quails, randomly distributed according to either substitution rate of soybean meal by the AKC (0%, 10%, 20%, or 30%) or farming phase. Results: The average daily gain from the 1st to 45th days (average daily gain1–45d) was found to be the highest (4.24 g/d/subject, p=0.021) for the 30% AKC-supplemented feed lot in either starter or finish incorporation (DFTAA), having an optimum final live weight of 193.4 g (p=0.028), a lowest feed conversion ratio of 3.08 (p=0.001), and a daily feed intake of 860 g (p=0.01). Carcass yield was recorded the highest (74.4%, p=0.02) with an optimum meat protein level (30.6%, p=0.024) and the lowest fat content (2.26%, p=0.001) for the same group as well. Conclusion: The partial substitution of soybean meal by AKC in the quails' fattening feeding, during the finishing phase and for all rearing phases, led to a better growth performance, a better carcass yield, and an improved chemical composition of meat.

Aim: This study was aimed to evaluate dietary crude protein (CP) level on performance of body weight (BW) gain, carcass production, and nitrogen emission on lambs. Materials and Methods: A total of 12 male thin-tailed lambs (15.2±1.8 kg initial BW and aged 3-4 months) were assigned to completely randomized design for 84-day feeding trial. The animals were divided into three different levels of CP (i.e., 14%, 16%, and 18% with isocaloric diets and 60% total digestible nutrients) with four replications. Results: Increasing CP level was not significantly affected on average daily gain (ADG), carcass production, N and N2O emissions, and efficiency of emissions related to the productions. The average of ADG, carcass production, meat production, meat protein production, N emission, and N2O emission was 141.4 g, 11.6 kg, 6.8 kg, 0.9 kg, 53.1 g/day, and 0.3 g/day, respectively. The efficiency of ADG, carcass production, meat production, and meat protein related to N emissions were 119.7 g/kg, 4.4 g/kg, 2.5 g/kg, and 56.6 g/kg, respectively, while N2O emissions related to ADG, carcass production, meat production, and meat protein were 2.4 g/kg, 0.027 g/kg, 0.36 g/kg, and 0.34 g/kg, respectively. Conclusion: It can be concluded that the increase of CP level up to 18% did not affect productivity, N emissions, and efficiency of emissions per unit product because the increase of CP was not balanced by energy content in feed.

Abstract A feedlot study was conducted comparing a natural feed additive (essential oils blend) at varying silage inclusions on receiving and finishing performance. The study utilized 480 crossbred steers (initial shrunk BW 296 kg ± 7.72 kg) in 48 pens with 10 steers/pen and 8 pens per treatment. Treatments were designed as a 2 × 3 factorial with 3 inclusions of corn silage [14, 47, 80 %; dry matter (DM) basis] with or without (+, -) the inclusion of an essential oils (EO) blend. All treatment diets contained 16% modified distillers grains plus solubles and 4% supplement with dry-rolled corn replacing corn silage (CS) on a DM basis. Steers were fed at 80% CS inclusion and adapted to 47% and 14% CS over a 10 and 24-d period, respectively. Cattle fed 80% CS were fed for 238 days, 47% CS for 195 days, and 14% CS were fed for 168 days to a common backfat of 1.28 cm (P > 0.59). There were no interactions for corn silage inclusion and the inclusion of essential oils on final body weight (FBW), dry matter intake (DMI), average daily gain (ADG), gain to feed ratio (G:F), hot carcass weight (HCW), longissimus muscle (LM) area, marbling, or calculated yield grade (CYG; P > 0.15). There was no significant difference for FBW, DMI, ADG, G:F, HCW, LM area, marbling, or CYG for cattle fed EO or no EO. However, there was a quadratic response for FBW, ADG, G:F, HCW, marbling and CYG with increased inclusion of corn silage (P < 0.04). Feeding corn silage at greater inclusions decreased animal performance but increased final body weight when fed to an equal fatness. Essential oils did not affect animal performance or carcass characteristics. However, feeding greater amounts of corn silage can be an economical way to finish cattle.
