“…Our results of increasing ADG of lambs with increasing concentrate level in diets are consistent with results of (29,30,31). Also, (32,33) indicated that the ADG and FCR of lambs were better in high concentrate diets than low C diets under intensive system of production. Similar types of observations were also recorded by (34) in lambs, (18,35) in kids.…”

The goal of this study was to examine the influence of feeding different concentrate roughage ratios on growth, reproductive parameters and behavior of sheep. The study design involved the use of a 30 sexually mature ewes assigned to three groups consisting of three ratios of concentrate (C) to roughage (R), Group1. 80%C: 20%R, Group2. 70%C: 30%R and Group3. 60%C: 40%R. The variables of the studies were live weight changes and Body condition score (BCS) of ewes during pregnancy and postpartum till weaning and behavior of ewes in addition to the birth weight and average daily gain of neonatal lambs and subsequent changes till weaning. The conception rate of ewes and their overall reproductive performance are under investigation. The results reveled that, different ratios of concentrate and roughage feeding had no significant effect on body weight, BCS and average dry matter intake of ewes during pregnancy and postpartum till weaning. Lambs birth weight and subsequent weights till weaning and average daily gain were significantly (P≤0.05) increased by feeding on ration contain 80%C: 20% R, followed by those feeding on 70% C: 30% R and lowest in those feeding on 60% C: 40%R. Rumination was significantly increased in Group3 lambs than other groups. Higher concentrate ratios had positive effect on reproductive performance of ewes and body weight, daily body weight gain and neonatal behavior of lambs till weaning.

“…[ 96 ] were of the same opinion that sorghum straw could be used as a sole roughage source at 60% level in complete pellet feed for intensive goat production. MS, a potential cereal crop residue hitherto unused could be incorporated as roughage component in complete rations at 50-60% level for obtaining optimum growth with better feed efficiency in growing lambs [ 97 ].…”

Effective utilization of available feed resources is the key for economical livestock rearing. Complete feed system is one of the latest developments to exploit the potential of animal feed resources in the best possible way. The complete feed is a quantitative mixture of all dietary ingredients, blended thoroughly to prevent separation and selection, fed as a sole source of nutrients except water and is formulated in a desired proportion to meet the specific nutrient requirements. The concentrate and roughage levels may vary according to the nutrient requirement of ruminants for different production purposes. The complete feed with the use of fibrous crop residue is a noble way to increase the voluntary feed intake and thus animal’s production performance. In this system of feeding, the ruminant animals have continuous free choice availability of uniform feed mixture, resulting in more uniform load on the rumen and less fluctuation in release of ammonia which supports more efficient utilization of ruminal non-protein nitrogen. Feeding complete diet stabilizes ruminal fermentation, thereby improves nutrient utilization. This feeding system allows expanded use of agro-industrial byproducts, crop residues and nonconventional feeds in ruminant ration for maximizing production and minimizing feeding cost, thus being increasingly appreciated. However, to extend the concept extensively to the field and make this technology successful and viable for farmers, more efforts are needed to be taken.

“…Rahayu et al [ 13 ] reported that Bligon goats given TMR based on Napier grass fresh forage resulted in a higher nutrient intake than TMR based on BMR or super-2 sorghum silage. This significant variation in BW was affected by the variation in concentrate level and nutrient content in the TMR [ 7 ]. Body weight gain was influenced by various factors, such as genetic and environmental factors.…”

“…Nevertheless, due to the high lignin content, sorghum has lower digestibility than maize, which restricts its use in ruminant feeding [ 5 , 6 ]. Sorghum forage can be used as roughage in small ruminant feeding at different levels without affecting intake, digestibility, and nitrogen balance [ 7 ]. Sorghum forages are usually processed into silage to remove the prussic acid content.…”

Objectives: The goal of this research was to figure out the effect of the local sorghum as silage on the performance of Bligon goats. Microbial protein synthesis, digestible nutrients, and average daily weight gain (ADWG) were measured to evaluate the goats’ performance. Materials and Methods: The study was designed in a completely randomized design with a one-way pattern. Twelve female Bligon goats with 24.33 ± 2.83 kg (mean ± SEM) initial body weight were divided into three groups of total mixed ration (TMR) treatments. Group 1 received fresh Napier grass (FNG) as a control, group 2 received imported sorghum silage (ISS) of brown midrib resistance (BMR), and group 3 received local sorghum silage (LSS) of super-2. Analysis of variance was used to analyze the data on microbial protein synthesis and feed intake during the research. On the contrary, analysis of covariance was used to analyze ADWG with initial weight as a covariate. Results: Microbial protein synthesis, feed-intake, and ADWG of goats that received TMR based on silage of two varieties of sorghum, namely BMR (ISS) and super-2 (LSS), were lower (p < 0.05) than control. However, there was no significant difference between both TMR based on sorghum silages. ISS’s feed conversion was better than LSS (p < 0.05), and FNG was the best. Sorghum silage as a basal ration in TMR had lower microbial protein synthesis but higher total digestible nutrient content than fresh forage, such as Napier grass. The sorghum varieties did not affect the microbial protein synthesis, digestible nutrients, and ADWG of Bligon goats. However, ISS treatment had higher feed efficiency than LSS. Conclusion: The local sorghum (super-2) silage can be used as ruminant feed as well as imported sorghum (BMR) offered as TMR. However, regardless of the cultivar, TMR based on sorghum silage cannot replace TMR based on fresh Napier grass.
