Bezerra AS, dos Santos MAS, Lourenço-Júnior JDB. Technologies Used in Production Systems for Santa Inês Sheep: A Systematic Review. Front Vet Sci 2022; 9:896241. [PMID: 35711795 PMCID: PMC9195131 DOI: 10.3389/fvets.2022.896241] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Accepted: 05/02/2022] [Indexed: 11/13/2022] Open
Abstract
This study identifies the number of publications that presented technologies used in the production systems of Santa Inês sheep in the last 5 years (2017–2021) carried out in Brazil. Therefore, the objective was to identify where we are in terms of knowledge about technologies in different fields (health, reproduction, animal breeding, behavior and welfare, nutrition and feeding, forage and pasture, carcass and meat quality, and economics and management of livestock systems). After rigorous selection, 114 studies were appointed and classified by knowledge field, and the main approaches within each theme were evaluated, pointing out research gaps. Most technologies have been in northeastern states. However, government agencies should develop public policies to disseminate techniques in rural areas because the production system in this region is still subsistence. This study highlighted the need for works that present management practices and tools that impact the improvement of animal welfare. Agro-industrial by-products have been widely used as an alternative for sheep feeding. However, economic feasibility analyses are recommended with these foodstuffs to substantiate their use as an option to reduce production costs. There is a lack of research allusive to the management of production systems, especially those related to estimates of economic feasibility indicators.

Viana PT, de Carvalho GGP, Viana MCP, de Assis DYC, de Figueiredo MP, Cirne LGA, Figueredo JS, Sousa LS, de Santana Júnior HA, Pina DDS, Alba HDR. Effect of high-concentrate diets with calcium lignosulfonate and cottonseed processing method on quantitative traits and non-carcass components of feedlot cull ewes. Arch Anim Breed 2021; 64:355-363. [PMID: 34514082 PMCID: PMC8428082 DOI: 10.5194/aab-64-355-2021] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Accepted: 08/03/2021] [Indexed: 12/02/2022] Open
Abstract
This study examined the effects of cottonseed processing form and
the inclusion of calcium lignosulfonate in high-concentrate diets for
feedlot cull ewes on carcass traits and non-carcass components. Thirty Santa
Inês cull ewes with an average body weight of 44.2 ± 5.2 kg and an
average age of 50 months were distributed into collective stalls in a
completely randomized design. The treatments consisted of diets including
whole cottonseed, crushed cottonseed, whole cottonseed treated with
lignosulfonate (100 g/kg, as fed), crushed cottonseed treated with
lignosulfonate (100 g/kg, as fed), and a control diet without cottonseed.
The experimental diets did not influence (P>0.05) average daily
weight gain (0.195 kg/day), slaughter weight (51.74 kg), or in vivo biometric and
on-carcass measurements. There was no difference (P>0.05) in
loin-eye area or subcutaneous fat thickness as evaluated in vivo by ultrasound.
There was no diet effect on hot carcass weight and yield (24.8 kg and
47.8 %), cold carcass weight and yield (24.2 kg and 46.8 %), or chilling
loss (2.1 %). Non-carcass components did not differ in response to the
diets (P>0.05). Dietary inclusion of calcium lignosulfonate
increases the proportions of udder and liver relative to empty body weight
(P<0.05). Neither the cottonseed processing method nor the
inclusion of calcium lignosulfonate in high-concentrate diets for cull ewes
affects their performance, biometric or morphometric measurements,
non-carcass components, or qualitative traits of their carcass.

Seankamsorn A, Cherdthong A, So S, Wanapat M. Influence of chitosan sources on intake, digestibility, rumen fermentation, and milk production in tropical lactating dairy cows. Trop Anim Health Prod 2021; 53:241. [PMID: 33811551 DOI: 10.1007/s11250-021-02697-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Accepted: 03/29/2021] [Indexed: 11/27/2022]
Abstract
The aim of study was to compare the influence of chitosan sources (commercial chitosan vs chitosan extract) on rumen fermentation, methane (CH4) emission, and milk production in tropical lactating dairy cows. Six lactating Holstein-Friesian crossbreeds (410 ± 5 kg, 120 ± 21 day-in-milk) were arranged in a 3 × 3 replicated Latin square design. In addition to control, a 2% chitosan extract supplement and a 2% commercial chitosan supplement of dry matter intake were the treatments. The results denoted that no significant differences on daily dry matter, nutrients, or estimated energy intake were noted when cows received different sources of chitosan. Nutrient digestibility was not influenced differently by extraction-based or commercial chitosan supplements. The pH, temperature, ammonia nitrogen, blood urea, and microbial count were similar among treatments. The different sources of chitosan supplements did not change the totals of volatile fatty acids, acetate, and butyrate; in contrast, different chitosan sources influenced (P<0.05) propionate content. The ruminal acetate to propionate ratio was markedly (P<0.05) reduced with chitosan supplement, but no change appeared between sources of chitosan. At 4 h after feeding, the methane estimation significantly decreased with the addition of chitosan supplementation (P<0.05) compared to the control group. The purine derivatives and microbial protein synthesis were not altered by the treatments. No significant differences existed on milk yield, milk composition, or milk urea nitrogen when cows received different sources of chitosan (P>0.05). In summary, supplementing extracted chitosan showed more potential than did the commercial chitosan for enhancing economic efficiency and recycling shrimp residues, therefore, reducing environmental waste.
