[PMID: 38107133 PMCID: PMC10724579 DOI: 10.1002/fsn3.3687] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 08/28/2023] [Accepted: 08/30/2023] [Indexed: 12/19/2023] Open
Abstract
The productivity of small ruminants in Ethiopia is low due to a shortage of feed supply throughout the year, both in terms of quality and quantity. This problem leads to the utilization of locally available lignocellulose by-products, which encompass high cellulose, hemicellulose, and lignin. It is known that the nutritive value of these lignocellulose by-products can be improved through biological, chemical, or a combination of both treatments This study was aimed at evaluating body weight change, carcass characteristics, and economic efficiency of rams fed a total mixed diet containing biologically treated rice husk (RH) or sugarcane bagasse (SCB). Thirty-six sheep, weighing an average initial body weight of 18 ± 1.8 kg were used. Two feeds (SCB and RH) and three biological treatments (Control, Trichoderma viride [Tv], and effective microbes [EM]) were used with a randomized complete block design (RCBD) in 2 × 3 factorial arrangements. Ram fed on RH containing diets had higher dry matter intake (DMI) (g/h/day), DMI (% of BW), DMI (g/kg BW0.75), average daily gain (ADG) (106 vs. 53 g/day), and feed conversion efficiency (FCE) (0.107 vs. 0.076) than SCB containing diets. Ram fed diets containing biologically treated roughages had significantly higher (p < .05) DMI (g/h/day), DMI (% of BW), DMI (g/kg BW0.75), ADG, and FCE. However, no significant differences were observed between sheep fed diets containing EM and Tv in DMI (g/h/day), DMI (% of BW), DMI (g/kg BW0.75), ADG, and FCE. This study also revealed that significantly (p < .05) higher carcass weight, dressing percentage (DP), rib eye muscle area, total non-carcass fat, and total edible offal components had been recorded for rams fed diets containing RH as roughage source related to rams fed diets containing SCB. While other parameters were unaffected by treatments, sheep fed diets containing biologically treated feed had a higher hot carcass weight plus DP. However, no significant (p > .05) difference was found between diets based on biologically treated roughage. Profitability analysis indicated that sheep fattening on a diet containing RH and by-products treated with Tv and EM showed greater profitability than untreated SCB. The authors had concluded that fattening sheep on diets containing RH results in higher feed intake, better body weight gain, more carcasses and higher profits, but optimum inclusion levels need further research, for either treated or untreated SCB.

Mekonen T, Tolera A, Nurfeta A, Bradford BJ, Yigrem S. Effects of substituting noug seed cake with pigeon pea leaves or desmodium hay on performance of male dairy calves. Trop Anim Health Prod 2023; 55:155. [PMID: 37041315 DOI: 10.1007/s11250-023-03538-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Accepted: 03/06/2023] [Indexed: 04/13/2023]
Abstract
This experiment was conducted to evaluate the effects of substituting 50% of noug seed cake (NSC) in a concentrate mixture with pigeon pea leaves (PPL) or desmodium hay (DH) on feed intake, digestibility, body weight gain, carcass composition, and meat quality of crossbred male dairy calves. Twenty-seven male dairy calves at 7-8 months of age with an average initial body weight of 150 ± 31 kg (mean ± SD) were assigned to 3 treatments in a randomized complete block design with 9 replications. Calves were blocked based on their initial body weight and assigned to the 3 treatments. All calves were fed native pasture hay ad libitum (at ⁓10% refusal) supplemented with a concentrate containing 24% NSC (treatment 1) or supplemented with a concentrate where 50% of NSC was replaced with PPL (treatment 2) or a concentrate where 50% of NSC was replaced with DH (treatment 3). Feed and nutrient intake, apparent nutrient digestibility, body weight gain, feed conversion ratio, carcass composition, and meat quality (except texture) were similar (P > 0.05) among treatments. Treatments 2 and 3 had more (P < 0.05) tender loin and rib meat than treatment 1. It can be concluded that 50% of NSC in the concentrate mixture can be replaced with either PPL or DH in growing male crossbred dairy calves to achieve similar growth performance and carcass characteristics. Since the substitution of 50% NSC either with PPL or DH resulted in similar outcomes in almost all responses measured, it is recommended to evaluate the complete substitution of NSC either with PPL or DH on the performance of calves.

Effect of feeding different proportions of pigeon pea ( Cajanus cajan) and neem ( Azadirachta indica) leaves on feed intake, digestibility, body weight gain and carcass characteristics of goats. Vet Anim Sci 2020; 8:100079. [PMID: 32734096 PMCID: PMC7386697 DOI: 10.1016/j.vas.2019.100079] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2018] [Revised: 06/18/2019] [Accepted: 09/25/2019] [Indexed: 11/28/2022] Open
Abstract
Supplementation of sole neem leaf meal instead of concentrate mix and pigeon pea leaf meal resulted in similar performance of goats. Neem and pigeon pea leaf supplementation has a significant effect on dressing percentage on the basis of slaughter weight and empty body weight was higher. Based on economic benefit the use of sole neem leaf meal instead of concentrate mix and pigeon pea leaf meal was displayed reduction of feed cost and increase of net return.
A 90-day experimental trial was conducted to investigate the growth performance and carcass parameters of goats supplemented with dry pigeon pea (PP) and neem leaves (NL). Thirty six yearling intact male Gumuz goats with initial mean body weight of 14.1 ± 1.5 kg (means ± SD) were allotted through a randomized complete block design to 6 treatments and 6 replicates. The supplement was given at 300 g DM/(animal·d). The experimental treatments were 300 g concentrate mix (CM), 300 g PP, 75 g NL + 225 g PP, 150 g NL + 150 g PP, 225 g NLM and 75 g PP and 300 g NL supplement. Total DM intake and basal feed DM intake were not significantly (P > 0.05) affected by supplementary diets. Intake of supplement and apparent DM digestibility were higher (P < 0.05) in goats supplemented with 300 g NL. Average daily gain, final body weight and feed conversion efficiency were not different (P > 0.05) among treatments. Dressing percentage on the basis of slaughter weight and empty body weight was higher (P < 0.05) in goats supplemented with 300 g NL than other treatments, but not differ with goats supplemented with 300 g CM. In conclusion, supplementation of sole NL instead of concentrate mix and PP resulted in similar performance of goats, and all supplements used in this study induced favorable average daily gain and thus can be employed in feeding systems depending on their availability and relative cost.

Abstract
An in vivo digestibility trial was conducted to evaluate the digestibility of six forages. These were selected indigenous browse species and groundnut haulms in Lawra and Jirapa Districts of the Upper West Region of Ghana. Groundnut haulms served as a control due to its known good digestibility in small ruminants. Thirty West African Dwarf (WAD) young castrated billy goats with a mean age of 8 months were used. The average live body weight was 8.9 ± 0.1 kg. The animals were randomly assigned to the six treatments and replicated five times in a completely randomized design. They were confined in metabolism cages. The adaptation period was 3 weeks after which data was taken for 10 days. The treatments were the leaves and tiny twigs of T1 Annona senegalensis, T2 Ficus gnaphalocarpa, T3 Pericopsis laxiflora, T4 Pterocarpus erinaceus, T5 Afzelia africana, and T6 (control) Arachis hypogaea. Feed intake, faecal matter and urine output were measured. The results indicated that dry matter (DM) contents of the feedstuffs were less than 50% but crude protein (CP) contents were higher than the minimum required for sustaining ruminants. Neutral and acid detergent fibre contents were high, and F. gnaphalocarpa, in particular, contained a higher level of phosphorus (P). The amounts of feed intakes were typical of most fodder species with the exception of P. laxiflora and P. erinaceus, which were lower (P < 0.05). The apparent digestibility values were also typical of most fodder species but the digestibility of A. africana fibre appeared to be lower. Nitrogen retention was positive for all test species with the exception of P. laxiflora, which was negative. Mortality was recorded in animals on P. laxiflora, and the rate was high. Pericopsis laxiflora leaves, even though morphologically similar to the leaves of P. erinaceus, were not a suitable fodder. Ficus gnaphalocarpa appeared to be the overall best fodder species in terms of nutrient uptake.

Abstract
Abstract In recent years sheep, farming has emerged as an alternative production system especially in dry areas. The use of leaves and fruit from some trees has become an alternative for feeding for ruminants; however, studies on these species are scarce. The objective of this study was to evaluate the effect of S. spectabilis fruit meal on in vivo and in vitro digestibility, blood metabolites, and ruminal kinetics in hair lambs. This study was carried out at Las Brisas farm, University of Tolima - Colombia. Twelve male hair lambs with body weight of 20.3 ± 2.5 kg were used. Animals were distributed in an experimental 4x4 Latin square design. The treatments consisted of diets based on Dichanthium spp hay with different inclusion levels of S. spectabilis fruit meal (15, 30, and 45%). A linear increasing effect (P <0.05) was observed for in vivo and in vitro digestibility of dry matter, organic matter, and crude protein; likewise, plasma urea and ruminal degradability increased as the level of supplementation of S. spectabilis increased. The meal of S. spectabilis improves digestibility, protein intake, and ruminal kinetics in hair lambs; therefore, it is suggested as a promising alternative for ruminants feeding in dry tropic regions.

Abstract
The study was conducted to evaluate the effect of feeding different levels of sun-dried Ziziphus spina-christi (ZC) leaves on feed intake and live weight gain of local male goats. Twenty-five male local breed of goats at 1 year of age (body weight; BW = 20.7 ± 0.72 kg) were randomly allocated to five treatments and five replications. Treatments were as follows: T1 (grass hay only; control group); T2 (75% grass hay + 25% ZC leaves); T3 (50% grass hay + 50% ZC leaves); T4 (25% grass hay + 75% ZC leaves), and T5 (100% ZC leaves). The study lasted for 90 days. During this period, feed intake, BW change, and average daily gain were evaluated. There was a significant difference in total dry matter intake of goats fed on different levels of ZC leaves compared with the control group. Mixing of the pasture grass hay diet improved (P < 0.05) goats feed intake from 440 to 592 g/head/day at the minimum proportion of 25% ZC and natural pasture mixture. However, there was no significant difference (P > 0.05) in feed intake among the supplemented groups (T2-T5) as ZC leaves proportion increased. Goats in the control group and in the 25% ZC treatment diet gained 31.4 and 46.7 g, which was not different (P > 0.05). The highest average daily BW was gained (P < 0.05) in goats supplemented with the highest level (100%) of ZC leaves. T5 (100% ZC leaves supplementation) showed a significant increment (P < 0.05) in body weight gain of goats over other treatments and the control. Feed conversion ratio was increased (P < 0.05) with increased inclusion level of ZC leaves. Goats on supplemented treatments 1 and 2; treatments 4 and 5 had no significant difference (P > 0.05) in feed conversion efficiency while there was a significant (P < 0.05) difference between treatments 2 and 3 diets which had higher (P < 0.05) feed conversion ratio than the control groups. Generally, the results of the current study showed that supplementation of goats with above 50% level of dried ZC leaves in their diet significantly increased feed intake and body weight gain by improving feed conversion efficiency of goats.

Abstract
The objective of this study was to determine the effect of supplementing increasing levels of dried tagasaste (Chamaecytisus palmensis) leaf on the nutrition and performance of sheep fed a basal diet of barley straw. The study had four treatments, which involved supplementation of dried tagasaste leaf at 100, 200, 300, and 400 g/day. Twenty-four yearling Menz sheep (weight 17 ± 0.83 kg) were assigned to one of the four treatments in a randomized complete block design. The experiment comprised a feeding trial lasting for 90 days, a digestibility trial, and carcass evaluation using all animals. Samples of the feed consumed, refused, and feces were analyzed for nutrients. Intake and digestibility of dry matter (DM) and nutrients increased linearly (P < 0.001) as tagasaste supplementation increased from 100 to 400 g/day. Similarly, average daily body weight gain increased linearly (P < 0.001) from 20 to 73 g/day, feed conversion efficiency from 0.04 to 0.10, and dressing percentage from 40 to 48%, as the supplementation increased from 100 to 400 g/day. Proportion of tagasaste leaf in the diet increased from 20 to 50%, while the ratio of neutral detergent fiber (NDF) to crude protein (CP) decreased from 7.9 to 5.3, as the level of supplementation increased. It was thus concluded that supplementation of dried tagasaste leaf up to 50% of the diet DM, resulting in a NDF:CP ratio of 5.3, produces no deleterious effects on the performance of sheep, and inclusion to this level can be applied for superior growth performance and carcass yield in sheep fed crop residue-based diets.

Abstract
The effects of feeding graded levels of dried moringa (Moringa stenopetala) leaf on intake, body weight gain (BWG), digestibility and nitrogen utilization were studied using male sheep (BW of 13.8 ± 0.12 kg). Six sheep were randomly allocated to each of the four treatment diets: Rhodes grass (Chloris gayana) hay offered ad libitum (T1), hay + 150 g moringa leaf (T2), hay + 300 g moringa leaf (T3), hay + 450 g moringa leaf (T4) were offered daily. A 7-day digestibility trial and an 84-day growth experiments were conducted. Dry matter (DM), organic matter (OM) and crude protein (CP) intakes increased (P < 0.05) with increasing levels of moringa leaf in the diets. Sheep fed T2, T3 and T4 diets gained (P < 0.05) 40.2, 79.1 and 110.1 g/head/day, respectively, while the control group (T1) lost weight (-13.3 g/head/day). The apparent digestibilities of DM, OM, neutral detergent fibre and acid detergent fibre were similar (P > 0.05) among treatments. The digestibility of dietary CP increased (P < 0.05) with increasing levels of moringa leaf, but there was no significant difference between T2 and T3 diets. The nitrogen (N) intake and urinary N excretion increased (P < 0.05) with increasing levels of moringa leaf. The N retention was highest (P < 0.05) for 450 g moringa leaf supplementation. The control group was in a negative N balance. Supplementing a basal diet of Rhodes grass hay with dried moringa leaves improved DM intake, BWG and N retention. It is concluded that M. stenopetala can serve as a protein supplement to low-quality grass during the dry season under smallholder sheep production system.

Abstract
The replacement value of dried Erythrina brucei leaf for cotton seed meal (CSM) on growth performance and carcass characteristics was evaluated. Twenty-five yearling buck goats (15.8 ± 1.4 kg) were assigned into five treatments in a randomized complete block design: natural grass hay alone (T1) or supplemented with 100% CSM (T2), 67% CSM + 33% E. brucei (T3), 33% CSM + 67% E. brucei (T4), and 100% E. brucei (T5) on dry matter (DM) basis. Supplemented goats consumed more (P < 0.05) total DM and organic matter (OM) than the non-supplemented group, but the intakes were not influenced (P > 0.05) by the proportion of the supplements. The highest (P < 0.05) crude protein (CP) intake was observed in goats supplemented with CSM alone, whereas the lowest intake was observed in the non-supplemented group. Total CP intake decreased (P < 0.05) with increasing levels of E. brucei in the supplement mixture. The supplemented goats gained more (P < 0.05) weight than the control group. Apparent DM and OM digestibility was higher (P < 0.05) in supplemented goats than in the non-supplemented ones, but similar (P > 0.05) among the supplemented group. The digestibility of CP was higher (P < 0.05) for supplemented goats, except in those goats fed E. brucei alone, than the non-supplemented group. Slaughter weight, empty body weight, hot carcass weight, dressing percentage, rib eye muscle area, and total edible offals were higher (P < 0.05) for supplemented goats than for the non-supplemented ones. It could be concluded that E. brucei could be used as a substitute to CSM under smallholder production systems.
